  • Have to dhclient each restart to access internet

    - by Zeophlite
    So each time I restart my ubuntu server (virtual 10.04, via Xencenter), I have to call dhclient before I can access the internet: http://img813.imageshack.us/i/dhclient.png/ What do I need to change to get internet access automatically? Apologies for posting images, I'm using Xencenter, so I can't copy/paste the console output EDIT:: daniel@workwork:~$ cat /etc/network/interfaces # This file describes the network interfaces available on your system # and how to activate them.

  • How to troubleshoot a PHP script that causes a Segmenation Fault?

    - by johnlai2004
    I posted this on stackoverflow.com as well because I'm not sure if this is a programming problem or a server problem. I'm using ubuntu 9.10, apache2, mysql5 and php5. I've noticed an unusual problem with some of my php programs. Sometimes when visiting a page like profile.edit.php, the browser throws a dialogue box asking to download profile.edit.php page. When I download it, there's nothing in the file. profile.edit.php is supposed to be a web form that edits user information. I've noticed this on some of my other php pages as well. I look in my apache error logs, and I see a segmentation fault message: [Mon Mar 08 15:40:10 2010] [notice] child pid 480 exit signal Segmentation fault (11) And also, the issue may or may not appear depending on which server I deploy my application too. Additonal Details This doesn't happen all the time though. It only happens sometimes. For example, profile.edit.php will load properly. But as soon as I hit the save button (form action="profile.edit.php?save=true"), then the page asks me to download profile.edit.php. Could it be that sometimes my php scripts consume too much resources? Sample code Upon save action, my profile.edit.php includes a data_access_object.php file. I traced the code in data_access_object.php to this line here if($params[$this->primaryKey]) { $q = "UPDATE $this->tableName SET ".implode(', ', $fields)." WHERE ".$this->primaryKey." = ?$this->primaryKey"; $this->bind($this->primaryKey, $params[$this->primaryKey], $this->tblFields[$this->primaryKey]['mysqlitype']); } else { $q = "INSERT $this->tableName SET ".implode(', ', $fields); } // Code executes perfectly up to this point // echo 'print this'; exit; // if i uncomment this line, profile.edit.php will actually show 'print this'. If I leave it commented, the browser will ask me to download profile.edit.php if(!$this->execute($q)){ $this->errorSave = -3; return false;} // When I jumped into the function execute(), every line executed as expected, right up to the return statement. And if it helps, here's the function execute($sql) in data_access_object.php function execute($sql) { // find all list types and explode them // eg. turn ?listId into ?listId0,?listId1,?listId2 $arrListParam = array_bubble_up('arrayName', $this->arrBind); foreach($arrListParam as $listName) if($listName) { $explodeParam = array(); $arrList = $this->arrBind[$listName]['value']; foreach($arrList as $key=>$val) { $newParamName = $listName.$key; $this->bind($newParamName,$val,$this->arrBind[$listName]['type']); $explodeParam[] = '?'.$newParamName; } $sql = str_replace("?$listName", implode(',',$explodeParam), $sql); } // replace all ?varName with ? for syntax compliance $sqlParsed = preg_replace('/\?[\w\d_\.]+/', '?', $sql); $this->stmt->prepare($sqlParsed); // grab all the parameters from the sql to create bind conditions preg_match_all('/\?[\w\d_\.]+/', $sql, $matches); $matches = $matches[0]; // store bind conditions $types = ''; $params = array(); foreach($matches as $paramName) { $types .= $this->arrBind[str_replace('?', '', $paramName)]['type']; $params[] = $this->arrBind[str_replace('?', '', $paramName)]['value']; } $input = array('types'=>$types) + $params; // bind it if(!empty($types)) call_user_func_array(array($this->stmt, 'bind_param'), $input); $stat = $this->stmt->execute(); if($GLOBALS['DEBUG_SQL']) echo '<p style="font-weight:bold;">SQL error after execution:</p> ' . $this->stmt->error.'<p>&nbsp;</p>'; $this->arrBind = array(); return $stat; }

  • htaccess on remote server issues - password prompt not accepting input

    - by pying saucepan
    EDIT: I will contact the university about my problem after labor day weekend, but I thought if someone knew a quick fix that I haven't tried, or if the problem has an obvious fix then I could hope to try my luck here, thanks! TLDR: Sorry its a long post, I thought I should be... thorough. I am having a common issue (found a dead thread through google with no solution to the same problem) with the prompt to enter in a username and password via htaccess rights, but this prompt will keep popping up asking for a username and password when trying to access my home directory on my university's server which has the .htaccess and .htpasswd files. It does not matter if I enter in correct or incorrect credentials, the prompt will keep asking me for input without displaying my home directory. Ever since I have included these ht files I have never once been able to get past the username/password no matter what I have tried, save for removing them from the directory I am trying to access (my top level directory that I own). This kind of served my original goal of making the top level directory inaccessible to casual users, but if I wanted to use this method on other places, I would want it to work as intended. And I also like it when computers do what I wish they would, so any help is appreciated. Some things I have tried: Changing the file/directory access rights: they told me to try these commands if people can't access my files cd ~/public_html find ./ -type d -exec chmod 755 {} \; find ./ -type f -exec chmod 644 {} \; enter in the single character name/pw at least twenty times in a row, no cheddar. so I changed directory with cd ~ in hopes that this would be my home directory, since my home directory contains the "public_html" directory, so logic tells me that the ~ tilde symbol is the top level directory that I have ownership of. Then I did those two commands to change the rights on the files inside, I am still having no luck. How I got to this point: I have been following the instructions given to me through my university's website for setting up my little directory. A link on how they describe how to password protect the home directory is given below: "Protect Web Directories" instructions I have everything in order except for one small detail that I feel probably does not matter. I am on windows and so I am using winSCP to remote control my allocated server space. The small detail is that as the instructions indicate (on step 3) that I should use the command htpasswd -c .htpasswd {username} where {username} is my folder that holds my allocated server space. But this command requires further input through the terminal, and unfortunately winSCP does not offer this kind of functionality. So I looked up some basic instructions on using htaccess and it is formatted correctly such that the .htaccess file appears as follows: AuthType Basic AuthName "Verify" AuthUserFile /correctpath/.htpasswd require valid-user and this file is in the root directory for my server space as well as the .htpasswd file which has only this data inside: username:password I know for sure that these two files must be formatted correctly, at least according to their tutorial, because before my path was incorrectly formatted via including some curly { braces } without knowing the correct way to do this at first. And the password prompt that shows up when accessing my directory responded by loading an error page indicating to contact OSU admin or something not important. But now that I have everything like it 'should' be. I know this because when I enter in my credentials "username and password" the prompt pops up for my username and password again and again whether or not I enter in correct information. The only exception is that if I click cancel it will direct me to a page saying that I need to enter in a username and password. Note that I am very inexperienced at server-related buisness, two days ago I couldn't have told you what a website actually consists of. So, if you use some technical jargon I may or may not need to look it up and get back to you before I actually understand what you mean, but I am a quick learner and it probably wont matter.

  • Raid 1 array won't assemble after power outage. How do I fix this ext4 mirror?

    - by Forkrul Assail
    Two ext4 drives on Raid 1 with mdadm won't reassemble after the power went out for an extended period (UPS drained). After turning the machine back on, mdadm said that the array was degraded, after which it took about 2 days for a full resync, which completed without problems. On trying to remount the array I get: mount: you must specify the filesystem type cat /etc/fstab lines relevant to setup: /dev/md127 /media/mediapool ext4 defaults 0 0 dmesg | tail (on trying to mount) says: [ 1050.818782] EXT3-fs (md127): error: can't find ext3 filesystem on dev md127.

Could someone explain why it would resync after the powerout, only to seemingly nuke the drive? Thanks for reading. Any help much appreciated. I've tried everything I can think of, including booting and filesystem checking with SystemRescue and Ubuntu liveboot discs.

  • Site-to-site VPN using MD5 instead of SHA and getting regular disconnection

    - by Steven
    We are experiencing some strange behavior with a site-to-site IPsec VPN that goes down about every week for 30 minutes (Iam told 30 minutes exactly). I don't have access to the logs, so it's difficult to troubleshoot. What is also strange is that the two VPN devices are set to use SHA hash algorithm but apparently end up agreeing to use MD5. Does anybody have a clue? or is this just insufficient information? Edit: Here is an extract of the log of one of the two VPN devices, which is a Cisco 3000 series VPN concentrator. 27981 03/08/2010 10:02:16.290 SEV=4 IKE/41 RPT=16120 xxxxxxxx IKE Initiator: New Phase 1, Intf 2, IKE Peer xxxxxxxx local Proxy Address xxxxxxxx, remote Proxy Address xxxxxxxx, SA (L2L: 1A) 27983 03/08/2010 10:02:56.930 SEV=4 IKE/41 RPT=16121 xxxxxxxx IKE Initiator: New Phase 1, Intf 2, IKE Peer xxxxxxxx local Proxy Address xxxxxxxx, remote Proxy Address xxxxxxxx, SA (L2L: 1A) 27986 03/08/2010 10:03:35.370 SEV=4 IKE/41 RPT=16122 xxxxxxxx IKE Initiator: New Phase 1, Intf 2, IKE Peer xxxxxxxx local Proxy Address xxxxxxxx, remote Proxy Address xxxxxxxx, SA (L2L: 1A) [… same continues for another 15 minutes …] 28093 03/08/2010 10:19:46.710 SEV=4 IKE/41 RPT=16140 xxxxxxxx IKE Initiator: New Phase 1, Intf 2, IKE Peer xxxxxxxx local Proxy Address xxxxxxxx, remote Proxy Address xxxxxxxx, SA (L2L: 1A) 28096 03/08/2010 10:20:17.720 SEV=5 IKE/172 RPT=1291 xxxxxxxx Group [xxxxxxxx] Automatic NAT Detection Status: Remote end is NOT behind a NAT device This end IS behind a NAT device 28100 03/08/2010 10:20:17.820 SEV=3 IKE/134 RPT=79 xxxxxxxx Group [xxxxxxxx] Mismatch: Configured LAN-to-LAN proposal differs from negotiated proposal.

  • apache webserver unresponsible with server-status showing all child processes waiting for connection

    - by Jeff
    My setup: i have 3 nearly identical webserver machines serving the same high loaded dynamic website with simple load balancing over dns. The service has been working for over two ears with the same apache config. apache2, php5, ubuntu 8.04 linux 2.6.24-29-server My problem: since about two weeks i'm experiencing problems with this config. Nearly every day i have one small moment about 5 minutes, in which the website is unreachable. I'm still able to login to the servers over ssh. If i run htop, i see the machine simply doing nothing. i have about 1000 apache processes running, but no cpu activity. i've used the apache mod_status to debug this situation. the process scoreboard looks like this: _C.___K_______________________R._______.__K_K____K___C_______.__ _______C__________.___________________________________.________C _.____K__________K___K_WK_____._K_____________________________._ W______K__________K________.____________________._______C_______ _C_.__K__K____.._.._____________________________________C_______ _R___________K___.______C________.C_________.______._____C______ ____________KKC____K_____K__WC_________________C_____.__.____.__ _____________________C_________K______.____C______._____________ _.___C____.___.___________________________.K______.____K________ W__.___________________C.__.____K________K_______R_._.__._______ __C__C_.__________C__C_______._____W______________C_.___C_______ ____.______C_____________C________.____C____________.________._K __.__________.K_____________K_________._____C____.K__________KW_ __K.W________R_________._______.___W___________.____.__K_____W__ W___.___..________W____K Scoreboard Key: "_" Waiting for Connection, "S" Starting up, "R" Reading Request, "W" Sending Reply, "K" Keepalive (read), "D" DNS Lookup, "C" Closing connection, "L" Logging, "G" Gracefully finishing, "I" Idle cleanup of worker, "." Open slot with no current process So the most of the processes are just waiting for connection. after about 5 minutes the situation will return to normal: i have lot least processes on every machine, the most workers have the "."-status (meaing they are open to process a request) and of course the website is reachable! so i'm trying to find something in the logs, but there is simply nothing... the apache access log is silent for about 4 minutes, the same is for the error log. i also can not figure out anything wrong in other system logs. the situation is the same on all 3 webservers (all of them have this load peak and unresposibility at the same time), so i do not thing this is hardware related. but i think, this might be related to some network (tcp) issue. any ideas? EDIT: some more information, that i have just discovered: it has just happened again. and i was able to verify that i'm also not able to connect locally when this problem occurs. i have made some connection statistics with the following command after it happend netstat -an|awk '/tcp/ {print $6}'|sort|uniq -c 109 CLOSE_WAIT 2652 ESTABLISHED 2 FIN_WAIT1 11 LAST_ACK 12 LISTEN 91 SYN_RECV 1 SYN_SENT 16 TIME_WAIT If i execute the same command some time later, i have something like this: 4 CLOSING 108 ESTABLISHED 18 FIN_WAIT1 182 FIN_WAIT2 37 LAST_ACK 12 LISTEN 50 SYN_RECV 11276 TIME_WAIT So in the normal situation i have only 100-200 open connections by clients beeing handled by apache in this moment. when i have this "crash", i have a lot more connections. what is the best way to analyse this? EDIT2: the important lines in apache2.conf are: KeepAlive On MaxKeepAliveRequests 20 KeepAliveTimeout 1 <IfModule mpm_prefork_module> ServerLimit 920 StartServers 30 MinSpareServers 80 MaxSpareServers 120 MaxClients 920 MaxRequestsPerChild 700 </IfModule> it is an apache2 prefork with php_mod. the server has 8GB ram and a 4gb swap partition.

  • Connection Timed Out - Simple outbound Postfix for PHP Contact form

    - by BLaZuRE
    Alright, so I only got Postfix for a PHP contact form that will send email to a single . I only want it to send out mail to a single external address ([email protected]). I have domain sub1.sub2.domain.com. I installed Postfix out of the Ubuntu repo, with minimal config changes. I cannot get Postfix to send mail externally (though it succeeds for internal accounts, which is unnecessary). The email simply defers if I generate an email using PHP mail(). If I try to form my own in telnet, right after rcpt to: [email][email protected][/email], I get a postfix/smtpd[31606]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 550 5.1.1 <[email protected]>: Recipient address rejected: example.com; from=<root@localhost> to=<[email protected]> proto=ESMTP helo=<localhost> when commenting out default_transport = error and relay_transport = error lines, I get the following: Jun 26 14:33:00 sub1 postfix/smtp[12191]: 2DA06F88206A: to=<[email protected]>, relay=none, delay=514, delays=409/0.01/105/0, dsn=4.4.1, status=deferred (connect to aspmx3.googlemail.com[74.125.127.27]:25: Connection timed out) Jun 26 14:36:36 sub1 postfix/smtp[12225]: connect to mta7.am0.yahoodns.net[98.139.175.224]:25: Connection timed out Jun 26 14:38:00 sub1 postfix/smtp[12225]: 22952F88208E: to=<[email protected]>, relay=none, delay=655, delays=550/0.01/105/0, dsn=4.4.1, status=deferred (connect to mta5.am0.yahoodns.net[67.195.168.230]:25: Connection timed out) My main.cf # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

  • How to stop Apache from crashing my entire server?

    - by CyberShadow
    I maintain a Gentoo server with a few services, including Apache. It's fairly low-end (2GB of RAM and a low-end CPU with 2 cores). My problem is that, despite my best efforts, an over-loaded Apache crashes the entire server. In fact, at this point I'm close to being convinced that Linux is a horrible operating system that isn't worth anyone's time looking for stability under load. Things I tried: Adjusting oom_adj for the root Apache process (and thus all its children). That had close to no effect. When Apache was overloaded it would bring the system to a grind, as the system paged out everything else before it got to kill anything. Turning off swap. Didn't help, it would unload memory paged to binaries of processes and other files on /, thus causing the same effect. Putting it in a memory-limited cgroup (limited to 512 MB of RAM, 1/4th of the total). This "worked", at least in my own stress tests - except the server keeps crashing under load (basically stalling all other processes, inaccessible via SSH, etc.) Running it with idle I/O priority. This wasn't a very good idea in the end, because it just caused the system load to climb indefinitely (into the thousands) with almost no visible effect - until you tried to access an unbuffered part of the disk. This caused the task to freeze. (So much for good I/O scheduling, eh?) Limiting the number of concurrent connections to Apache. Setting the number too low caused web sites to become unresponsive due to most slots being occupied with long requests (file downloads). I tried various Apache MPMs without much success (prefork, event, itk). Switching from prefork/event+php-cgi+suphp to itk+mod_php. This improved performance, but didn't solve the actual problem. Switching I/O schedulers (cfq to deadline). Just to stress this out: I don't care if Apache itself goes down under load, I just want the rest of my system to remain stable. Of course, having Apache recover quickly after a brief period of intensive load would be great to have, but one step at a time. Right now I am mostly dumbfounded by how can humanity, in this day and age, design an operating system where such a seemingly simple task (don't allow one system component to crash the entire system) seems practically impossible - or at least, very hard to do. Please don't suggest things like VMs or "BUY MORE RAM". Some more information gathered with a friend's help: The processes hang when the cgroup oom killer is invoked. Here's the call trace: [<ffffffff8104b94b>] ? prepare_to_wait+0x70/0x7b [<ffffffff810a9c73>] mem_cgroup_handle_oom+0xdf/0x180 [<ffffffff810a9559>] ? memcg_oom_wake_function+0x0/0x6d [<ffffffff810aa041>] __mem_cgroup_try_charge+0x32d/0x478 [<ffffffff810aac67>] mem_cgroup_charge_common+0x48/0x73 [<ffffffff81081c98>] ? __lru_cache_add+0x60/0x62 [<ffffffff810aadc3>] mem_cgroup_newpage_charge+0x3b/0x4a [<ffffffff8108ec38>] handle_mm_fault+0x305/0x8cf [<ffffffff813c6276>] ? schedule+0x6ae/0x6fb [<ffffffff8101f568>] do_page_fault+0x214/0x22b [<ffffffff813c7e1f>] page_fault+0x1f/0x30 At this point, the apache memory cgroup is practically deadlocked, and burning CPU in syscalls (all with the above call trace). This seems like a problem in the cgroup implementation...

  • Static route works on one computer, not the other

    - by Dan
    I have been struggling with this for a couple days now, maybe I just need some people with a fresh perspective to figure out what the issue is. Basically I have a bunch of computers that are being routed through a specific gateway in order to access a web page that is hosted internally on a separate subnet. I set up static routes on all of the computers, and they all work... except one. Here's what a route print -4 looks like for a working computer (Windows 7): =========================================================================== Interface List 14...xx xx xx xx xx xx ......Broadcom 802.11n Network Adapter 11...xx xx xx xx xx xx ......Realtek PCIe GBE Family Controller 1...........................Software Loopback Interface 1 12...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter 13...00 00 00 00 00 00 00 e0 Microsoft 6to4 Adapter 17...00 00 00 00 00 00 00 e0 Teredo Tunneling Pseudo-Interface =========================================================================== IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 10.xxx.xxx.230 10.xxx.xxx.94 20 10.zzz.zzz.0 255.255.255.0 10.xxx.xxx.147 10.xxx.xxx.94 21 10.xxx.xxx.0 255.255.255.0 On-link 10.xxx.xxx.94 276 10.xxx.xxx.94 255.255.255.255 On-link 10.xxx.xxx.94 276 10.xxx.xxx.255 255.255.255.255 On-link 10.xxx.xxx.94 276 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 10.xxx.xxx.94 276 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 255.255.255.255 255.255.255.255 On-link 10.xxx.xxx.94 276 =========================================================================== Persistent Routes: Network Address Netmask Gateway Address Metric 10.zzz.zzz.0 255.255.255.0 10.xxx.xxx.147 1 =========================================================================== And here's a route print -4 from the station that doesn't work (also Windows 7): =========================================================================== Interface List 10...xx xx xx xx xx xx ......Realtek PCIe GBE Family Controller 1...........................Software Loopback Interface 1 12...00 00 00 00 00 00 00 e0 Microsoft 6to4 Adapter 14...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter #2 16...00 00 00 00 00 00 00 e0 Teredo Tunneling Pseudo-Interface =========================================================================== IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 10.xxx.xxx.230 10.xxx.xxx.132 276 10.zzz.zzz.0 255.255.255.0 10.xxx.xxx.147 10.xxx.xxx.132 21 10.xxx.xxx.0 255.255.255.0 On-link 10.xxx.xxx.132 276 10.xxx.xxx.132 255.255.255.255 On-link 10.xxx.xxx.132 276 10.xxx.xxx.255 255.255.255.255 On-link 10.xxx.xxx.132 276 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 10.xxx.xxx.132 276 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 255.255.255.255 255.255.255.255 On-link 10.xxx.xxx.132 276 =========================================================================== Persistent Routes: Network Address Netmask Gateway Address Metric 10.zzz.zzz.0 255.255.255.0 10.xxx.xxx.147 1 =========================================================================== Both of these stations are running Windows 7. So essentially what I am trying to do here is route all traffic to the 10.zzz.zzz.0 subnet through the 10.xxx.xxx.147 gateway. Everything else should go through the 10.xxx.xxx.230 gateway. This is the intended behavior, and again it is working everywhere but that one station. I noticed that the Active Route metric costs differ between the two stations, but I am new to the routing table and I am not sure how that is impacting the behavior. I hope I have been able to explain the situation clearly. Any help would be much appreciated. I can provide any additional information if needed!

  • Unison synchronization problem. Roots are not identical after synchronization.

    - by binary255
    Hi. When I synchronize two folders using Unison, only one of the roots seems to be affected. Below are all the information I would think is necessary to figure out why it is working like it is. I'm using $ unison -version unison version 2.27.57 From the Ubuntu repositories. My work laptop: $ echo $UNISONLOCALHOSTNAME worklaptop $ pwd /home/userfoo $ ls -lAR .unison* .unison: total 8 drwxr-xr-x 2 userfoo userfoo 4096 2010-04-26 11:39 backups -rw-r--r-- 1 userfoo userfoo 231 2010-04-26 11:38 default.prf .unison/backups: total 0 .unisonroot: total 0 $ cat .unison/default.prf # Roots of the synchronization root = /home/userfoo/.unisonroot root = ssh://devel//home/userbar/.unisonroot path = * backuplocation = central backupdir = /home/.unison/backups backupprefix = $VERSION.bak $ mkdir .unisonroot/aDirectoryFrom-$UNISONLOCALHOSTNAME $ echo something >.unisonroot/aFileFrom-$UNISONLOCALHOSTNAME $ ls .unisonroot/ aDirectoryFrom-worklaptop aFileFrom-worklaptop And the Ubuntu server I want to synchronize with: $ echo $UNISONLOCALHOSTNAME workcmpuserbardevel $ pwd /home/userbar $ ls -lAR .unison* .unison: total 4 drwxr-xr-x 2 userbar userbar 4096 2010-04-26 11:38 .unison .unison/.unison: total 0 .unisonroot: total 0 $ mkdir .unisonroot/aDirectoryFrom-$UNISONLOCALHOSTNAME $ echo something >.unisonroot/aFileFrom-$UNISONLOCALHOSTNAME $ ls .unisonroot/ aDirectoryFrom-workcmpuserbardevel aFileFrom-workcmpuserbardevel I perform the unison synchronization: $ echo $UNISONLOCALHOSTNAME worklaptop $ unison Contacting server... Connected [//worklaptop//home/userfoo/.unisonroot -> //workcmpuserbardevel//home/userbar/.unisonroot] Looking for changes Warning: No archive files were found for these roots, whose canonical names are: /home/userfoo/.unisonroot //workcmpuserbardevel//home/userbar/.unisonroot This can happen either because this is the first time you have synchronized these roots, or because you have upgraded Unison to a new version with a different archive format. Update detection may take a while on this run if the replicas are large. Unison will assume that the 'last synchronized state' of both replicas was completely empty. This means that any files that are different will be reported as conflicts, and any files that exist only on one replica will be judged as new and propagated to the other replica. If the two replicas are identical, then no changes will be reported. If you see this message repeatedly, it may be because one of your machines is getting its address from DHCP, which is causing its host name to change between synchronizations. See the documentation for the UNISONLOCALHOSTNAME environment variable for advice on how to correct this. Donations to the Unison project are gratefully accepted: http://www.cis.upenn.edu/~bcpierce/unison Press return to continue.[<spc>] Waiting for changes from server Reconciling changes local workcmps... dir ----> aDirectoryFrom-worklaptop [f] file ----> aFileFrom-worklaptop [f] Proceed with propagating updates?

The desired result would have been that the two folders would have ended up being identical, holding the union of the contents of the two roots.

  • Alternative Methods of Sharing Folders in Windows?

    - by Blaenk
    Hey guys. I'm running Windows 7 and as of now I simply share folders as one usually does in Windows. I then have a MacBook with Leopard (Now Snow Leopard) which I use to connect to my computer to mount the shares by going to Finder, then CMD + K and typing smb://BlaenkPC (The name of my PC) into the address box. This consequently connects to my computer and mounts all of the shares. The problem is that sometimes, if for example I close my MacBook (Which makes it go to sleep) or sometimes even without doing that, the connection somehow drops. Sometimes I close the MacBook and upon re-opening it, everything still works; it's random. It still shows the computer as being connected, but it just shows 'loading' indefinitely. If I hit 'eject' with the intention of re-connecting to the computer, it disappears from the sidebar (The Computer Icon) in Finder, but I cannot re-connect. Activity Monitor (or ps aux, whichever) both show hung instances of umount; one for each share that was mounted. I cannot kill these processes with kill or killall (Yes, even with sudo, and sending signal -9). This has happened to me before, and here is another person who has experienced this. My question boils down to this: Is there an alternative method of sharing folders in Windows, that my Mac can read/understand, that is possibly more reliable and preferably just as fast? I usually use the mounted shares to watch television episodes off my computer, or movies, etc. (In other words, I open them in VLC and they automatically stream from my computer). As far as I can tell, this is a problem with the Samba protocol. I have heard of NFS, but I am not sure if I would have to re-format my drives, or what. I don't mind running a service or daemon to allow the sharing of the folders, I just want it to be done and hopefully in a better way than typical Windows shares through Samba. Usually when I encounter this problem, which is often (read: every day), I have no other option but to restart the MacBook. As I stated in the first question I linked to, shutting down and restarting don't work; I have to manually force the shutdown by holding the power button. I have not modified my installation of Mac OS X in any hackish way, so I doubt it's something with the Operating System, but worst come to worst, I might end up reformatting and doing a clean install to see if that fixes anything, as I am at a complete loss as to what may be causing the problem, and no one else seems to have any idea or care, despite there being quite a few people suffering from this problem, as my research has shown. Any pieces of information that can help are extremely appreciated. You don't have to answer every question on here, but maybe even some insight as to why it might not be possible to kill those hung umount instances for example, or why I may not be able to reconnect using samba (Is it something regarding the way the protocol works?). One thing to note is that I have another computer in the home network that doesn't seem to have this problem. However, it is also running Windows 7 (Note though that I am not using the homegroup feature, but the typical windows sharing feature). My only deduction is that the problem is being caused by the way the Mac (Or Samba implementation, whichever) is handling things. Perhaps it is a limitation.

  • what is the best mid/high-end class audio/music creation audio sound card?

    - by Chris
    Hello, I have a computershop myself, and I repair computers. But one of the things I really don't know (yet) is the performace od audio cards for music creation with midi. I have searched and searched and came up with some good reviews, but after browsing for a couple of hours I could't see the trees trough the forrest :-D (it's a dutch expression) At one moment I thought the M-Audio - Delta 1010LT would be a good PCIe card, later on I read that this card was released years ago. (but that could be false information) Also any personal expierence would be great, but not necessairy. I have searched a few cards, and I hope someone can help me make a choice for a friend of mine. He's buget is between $100 and $350 I know there are audio cards from $ 500 - $1850,- this is just too expensive.

  • LDAP object class violation: attribute ou not allowed in suffix?

    - by Paramaeleon
    I am about to set up a LDAP directory. It is used as a tool to communicate user permissions from a web application to WebDav file system access, e.g. adding a user to the web platform shall allow login to the file system with the same credentials. There are no other usages intended. Following this German tutorial which encourages the use of the attributes c, o, ou etc. over dc, I configured the following suffix and root: suffix "ou=webtool,o=myOrg,c=de" rootdn "cn=ldapadmin,ou=webtool,o=myOrg,c=de" Server starts and I can connect to it by LDAP Admin, which reports “LDAP error: Object lacks”. Well, there aren’t any objects yet. I now want to create the root and admin elements from shell. I created an init.ldif file: dn: ou=webtool,o=myOrg,c=de objectclass: dcObject objectclass: organization dc: webtool o: webtool dn: cn=ldapadmin,ou=webtool,o=myOrg,c=de objectclass: organizationalRole cn: ldapadmin Trying to load the file runs into an error, telling me that ou is not allowed: server:~ # ldapadd -x -D "cn=ldapadmin,ou=webtool,o=myOrg,c=de" -W -f init.ldif Enter LDAP Password: adding new entry "ou=webtool,o=myOrg,c=de" ldap_add: Object class violation (65) additional info: attribute 'ou' not allowed I am not using ou anywhere except in the suffix, so the question: Isn’t it allowed here? What is allowed here? Here is my answer. I am not allowed to post it as answer for 8 hours, so don’t mind that it is part of the question by now. I will move it outside some day, if I don’t forget to do so. There are numberous dependencies for the creation of elements, and error messages are rather confusing if you don’t know of the concept. The objectclass isn’t necessarily dcObject for the databases’ root node, as it is likely to guess when you read several tutoriales. Instead, it must correspond to the object’s type: Here, for a name starting with ou=, it must be organizationalUnit. I found this piece of information in these tables [Link removed due to restriction: Oops! Your edit couldn't be submitted because: We're sorry, but as a spam prevention mechanism, new users can only post a maximum of two hyperlinks. Earn more than 10 reputation to post more hyperlinks. Link is below]. Further on, the object class dictates which properties must and can be added in the record. Here, organizationalUnit must have an ou: entry and must not have neither dc: nor o: entry. The healthy init.ldif file looks like that: dn: ou=webtool,o=myOrg,c=de objectclass: organizationalUnit ou: LDAP server for my webtool dn: cn=ldapadmin,ou=webtool,o=myOrg,c=de objectclass: organizationalRole cn: ldapadmin Note: The page also states: “While many objectClasses show no MUST attributes you must (ouch) follow any hierarchy […] to determine if this is the really case.” I thought that would mean my root record would have to provide the must fields for c= and o= (c: and o:, respectively) but this isn’t the case. Link in answer is (1): http :// www (dot) zytrax (dot) com/books/ldap/ape/ "Appendix E: LDAP - Object Classes and Attributes"

  • vconfig created virtual interface and trunking - is the the interface untagged or tagged for that VLAN ID?

    - by kce
    I am trying to setup an additional VLAN on our Debian-based router/firewall (which exists as a virtual machine on Hyper-V), our core switch (an HP Procurve 5406) and a remote HP ProCurve 2610 that is connected via a WAN Transparent Lan Service (TLS) link. Let's work backwards from the network edge: The Debian server has an external connection attached to eth0. The internal interface is eth1, which is connected directly from our Hyper-V host to the 5406. The port that eth1 is attached to is setup as Trk12. The 2610 is attached to Trk9 (which trunks a whole slew of VLANs - Trk9 is our TLS head). I can successfully ping the management IP addresses for my VLAN from both switches but I cannot ping, from either switch, the virtual interface for my new VLAN on the Debian-base router and firewall. The existing VLAN works fine. What gives? The port eth1 is attached to is a trunk, the existing VLAN (ID 98) is untagged on the trunk, the new VLAN (ID 198) is tagged. VLAN 198 is tagged on Trk9 on the 5406 and on the 2610. I can ping the other switch's management IP (10.100.198.2 and 10.100.198.3) from the other respective switch. That leg of the VLAN works - however I cannot communicate with eth1.198's 10.100.198.1. I feel like I'm missing something elementary but what it is remains illusive to me. I suspect the issue is with the vconfig created eth1.198. It should pass the tagged VLAN 198 packets correct? But they cannot seem to get any further than the 5406. Communication on the existing VLAN 98 works fine. From the Debian box: eth1: eth1 Link encap:Ethernet HWaddr 00:15:5d:34:5e:03 inet addr:10.100.0.1 Bcast:10.100.255.255 Mask:255.255.0.0 inet6 addr: fe80::215:5dff:fe34:5e03/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:12179786 errors:0 dropped:0 overruns:0 frame:0 TX packets:20210532 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1586498028 (1.4 GiB) TX bytes:26154226278 (24.3 GiB) Interrupt:9 Base address:0xec00 eth1.198: eth1.198 Link encap:Ethernet HWaddr 00:15:5d:34:5e:03 inet addr:10.100.198.1 Bcast:10.100.198.255 Mask:255.255.255.0 inet6 addr: fe80::215:5dff:fe34:5e03/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1496 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:72 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:3528 (3.4 KiB) # cat /proc/net/vlan/eth1.198: eth1.198 VID: 198 REORDER_HDR: 0 dev->priv_flags: 1 total frames received 0 total bytes received 0 Broadcast/Multicast Rcvd 0 total frames transmitted 72 total bytes transmitted 3528 total headroom inc 0 total encap on xmit 39 Device: eth1 INGRESS priority mappings: 0:0 1:0 2:0 3:0 4:0 5:0 6:0 7:0 EGRESS priority mappings: # ip route 10.100.198.0/24 dev eth1.198 proto kernel scope link src 10.100.198.1 206.174.64.0/20 dev eth0 proto kernel scope link src 206.174.66.14 10.100.0.0/16 dev eth1 proto kernel scope link src 10.100.0.1 default via 206.174.64.1 dev eth0 # iptables -L -v Chain INPUT (policy DROP 6875 packets, 637K bytes) pkts bytes target prot opt in out source destination 41 4320 ACCEPT all -- lo any anywhere anywhere 11481 1560K ACCEPT all -- any any anywhere anywhere state RELATED,ESTABLISHED 107 8058 ACCEPT icmp -- any any anywhere anywhere 0 0 ACCEPT tcp -- eth1 any 10.100.0.0/24 anywhere tcp dpt:ssh 701 317K ACCEPT udp -- eth1 any anywhere anywhere udp dpts:bootps:bootpc Chain FORWARD (policy DROP 1 packets, 40 bytes) pkts bytes target prot opt in out source destination 156K 25M ACCEPT all -- eth1 any anywhere anywhere 215K 248M ACCEPT all -- eth0 eth1 anywhere anywhere state RELATED,ESTABLISHED 0 0 ACCEPT all -- eth1.198 any anywhere anywhere 0 0 ACCEPT all -- eth0 eth1.198 anywhere anywhere state RELATED,ESTABLISHED Chain OUTPUT (policy ACCEPT 13048 packets, 1640K bytes) pkts bytes target prot opt in out source destination From the 5406: # show vlan ports trk12 detail Status and Counters - VLAN Information - for ports Trk12 VLAN ID Name | Status Voice Jumbo Mode ------- -------------------- + ---------- ----- ----- -------- 98 WIFI | Port-based No No Untagged 198 VLAN198 | Port-based No No Tagged

  • I need to understand why my server turned off

    - by Dema
    Our organization was robbed and definitely it was inside job. I was set up. I work as a manager and as system administrator in this organization and everything goes against me. The only clue I have is that someone accidentally or intentionally turned of a server that is in the office indicating that some one was inside at the time that no one should be. This is the only evidence I have that can justify me.  I looked the log files and they show that the Power button was pressed. Can you help me to find out that that was not a bug or systems overheat? I will post the log files and if you will ask more I will gladly provide the information.

  • Choice and setup of version control

    - by Peter M
    I am about to set up an new laptop and in the process transition to a new version control system as part of a general cleanup. Currently I use a centralized version control system (yes it is VSS, and yes I know all the pro's and con's of that system, but as a single user system it works well for me). I have very little requirements for a new system and I am free to choose among any of the current mainstream players, but cost constraints will push me towards oss. Some of my requirements are: Runs on a single machine (ie the laptop in question) under windows I am not sharing things with other developers or workers - this is more for my own historical benefits. I want to version source code, documentation and binary files I have a large hierarchy of projects that are unrelated (see below) I have files within the hierarchy that don't need to be controlled (but could be) Some projects use Visual Studio, so some integration there could be nice. There could be some sharing of files between jobs. I generally only need a small about of branching in code files The directory hierarchy that I have at the moment is somewhat like: Root | |--Customer #1 | | | |--Job #1 | | | | | |--Data files received from Customer for Job (not controlled) | | |--Documentation files (controlled) | | |--Project information files (not controlled - but could be) | | |--Software Project Files (controlled) | | |--Scratch dir for job (not controlled) | | | |--Job #2 | | (same structure as above) | |--Customer #2 | |.. | |--Cusmtomer #n |.. Currently I have about 22 customers with differing numbers of projects underneath them. At the moment I have a single VSS repository based at the root of the directory structure. If I kept with a centralized system (ie SVN) I believe that I should keep the same approach and continue with a single repository based from the root dir. Is this a valid approach? However if I move to a distributed tool then I am unsure of how I should handle the situation. My initial guess is that I should not have a repository based on the root of my entire directory structure - but that is a guess so I really don't know how valid it is. Should I pitch a distributed approach at the Root, Customer, Job or sub-Job directory level? Also what I am not clear on with distributed tools (and perhaps with SVN as well), is if I can branch parts of a repository. For example, I can see branching source code in software projects as being useful, but branching my documentation as not being useful. So if I pitch a repository at the Job level, can I just branch the Software Project Files? Or would all files in that Job be branched? Every time I look at distributed tools I get a nagging feeling that they are not suited to my style of setup. I am uncomfortable with idea of having to manually set up something like 50 to 80 separate repositories (if I pitch at the Job level, or 20+ if at the Customer level) within my directory hierarchy. This feeling also extends to having all those repositories scattered around as well - however I do have a backup strategy that I trust, so this latter feeling is pretty well unfounded. So what advice can you all give me? Thanks in advance!

  • Proliant server will not accept new hard disks in RAID 1+0?

    - by Leigh
    I have a HP ProLiant DL380 G5, I have two logical drives configured with RAID. I have one logical drive RAID 1+0 with two 72 gb 10k sas 1 port spare no 376597-001. I had one hard disk fail and ordered a replacement. The configuration utility showed error and would not rebuild the RAID. I presumed a hard disk fault and ordered a replacement again. In the mean time I put the original failed disk back in the server and this started rebuilding. Currently shows ok status however in the log I can see hardware errors. The new disk has come and I again have the same problem of not accepting the hard disk. I have updated the P400 controller with the latest firmware 7.24 , but still no luck. The only difference I can see is the original drive has firmware 0103 (same as the RAID drive) and the new one has HPD2. Any advice would be appreciated.

  • Cannot open simple script application on mac

    - by streetpc
    Mac OS X 10.6 I created a very simple app, which is only a wrapper of a shell script (so that I can select this script in application selectors, like startup apps). I try to launch it and yesterday it worked, but today I changed the executable script's content and name (with something that perfeclty works in a shell script launched in the Terminal) and it will only display a Finder-iconed dialog saying Cannot open the application because it is not supported on this kind of Mac. I restored the previous script (content/name) but I still get the error! Same when re-bundling the app from scratch, or completely changing the bundle identifier… If I try to open it in the Terminal using open My.app, I get The application cannot be opened because it has an incorrect executable format. But when I executes directly the Contents/MacOS/Script, it allways works (iwth both contents). Also, it is displayed with correct icon and meta-information in the Finder (so I guess the Info.plist is understood). The app's file tree is: Contents/ Info.plist MacOS/ Script (executable bit set, works when launched directly) PkgInfo Resources/ AppIcon.icns Here is the Info.plist content: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CFBundleExecutable</key> <string>Script</string> <key>CFBundleIconFile</key> <string>AppIcon</string> <key>CFBundleIdentifier</key> <string>asdf.ScriptApp</string> <key>CFBundleInfoDictionaryVersion</key> <string>6.0</string> <key>CFBundleName</key> <string>My script</string> <key>CFBundlePackageType</key> <string>APPL</string> <key>CFBundleShortVersionString</key> <string>1.0</string> <key>CFBundleSignature</key> <string>????</string> <key>CFBundleVersion</key> <string>1</string> <key>LSMinimumSystemVersion</key> <string>10.4</string> </dict> </plist> And the PkgInfo file only contains APPL????. I tested the Script with a simple echo "ok" and echo "ok" >/tmp/test (plus #!/bin/sh header). So my questions are: Is there some kind of validity caching for applications ? based on what ? how do I flush it ? Where does this message come from ? I tried to google it but all I get is a page talking about 32/64 bits Java…

By if I try to sync from flags 'domhier', it wont resync; I get the error message The computer did not resync because no time data was available. I can only think that it is not querying the pdc. I also tried setting the registry as shown here (http://support.microsoft.com/kb/193825). But no luck (I have not restarted the server, I am hoping I wont have to since it is the pdc) If you would like any further information on my config, please let me know. Edit 1: I have set the w32time service config AnnouceFlags to 0x05 as documented here www.krr.org/microsoft/authoritative_time_servers.php and a number of other places. The PDC syncs to an external time source (ntp). I can get the stripchart on the client from the pdc no problems. The loginserver for the host I am trying to configure is shown as the pdc. Edit 2: The packet capture has revealed something interesting. The client is contacting the correct server, and getting a valid response but I still get the same error message. Here is the NTP excerpt from the client to the server Flags: 11.. .... = Leap Indicator: alarm condition (clock not synchronized) (3) ..01 1... = Version number: NTP Version 3 (3) .... .011 = Mode: client (3) Peer Clock Stratum: unspecified or unavailable (0) Peer Polling Interval: 10 (1024 sec) Peer Clock Precision: 0.015625 sec Root Delay: 0.0000 sec Root Dispersion: 1.0156 sec Reference Clock ID: NULL Reference Clock Update Time: Sep 1, 2010 05:29:39.8170 UTC Originate Time Stamp: NULL Receive Time Stamp: NULL Transmit Time Stamp: Nov 8, 2010 01:44:44.1450 UTC Key ID: DC080000 Here is the reply NTP excerpt from the server to the client Flags: 0x1c 00.. .... = Leap Indicator: no warning (0) ..01 1... = Version number: NTP Version 3 (3) .... .100 = Mode: server (4) Peer Clock Stratum: secondary reference (3) Peer Polling Interval: 10 (1024 sec) Peer Clock Precision: 0.00001 sec Root Delay: 0.1484 sec Root Dispersion: 0.1060 sec Reference Clock ID: 192.189.54.17 Reference Clock Update Time: Nov 8,2010 01:18:04.6223 UTC Originate Time Stamp: Nov 8, 2010 01:44:44.1450 UTC Receive Time Stamp: Nov 8, 2010 01:46:44.1975 UTC Transmit Time Stamp: Nov 8, 2010 01:46:44.1975 UTC Key ID: 00000000 Edit 3: dumpreg for paramters on pdc Value Name Value Type Value Data ------------------------------------------------------------------------ ServiceMain REG_SZ SvchostEntry_W32Time ServiceDll REG_EXPAND_SZ C:\WINDOWS\system32\w32time.dll NtpServer REG_SZ bhvmmgt01.domain.com,0x1 Type REG_SZ AllSync and config Value Name Value Type Value Data -------------------------------------------------------------------------- LastClockRate REG_DWORD 156249 MinClockRate REG_DWORD 155860 MaxClockRate REG_DWORD 156640 FrequencyCorrectRate REG_DWORD 4 PollAdjustFactor REG_DWORD 5 LargePhaseOffset REG_DWORD 50000000 SpikeWatchPeriod REG_DWORD 900 HoldPeriod REG_DWORD 5 LocalClockDispersion REG_DWORD 10 EventLogFlags REG_DWORD 2 PhaseCorrectRate REG_DWORD 7 MinPollInterval REG_DWORD 6 MaxPollInterval REG_DWORD 10 UpdateInterval REG_DWORD 100 MaxNegPhaseCorrection REG_DWORD -1 MaxPosPhaseCorrection REG_DWORD -1 AnnounceFlags REG_DWORD 5 MaxAllowedPhaseOffset REG_DWORD 300 FileLogSize REG_DWORD 10000000 FileLogName REG_SZ C:\Windows\Temp\w32time.log FileLogEntries REG_SZ 0-300 Edit 4: Here are some notables from the ntp log file on the pdc.

Ok so I was reading about people with similar problems, some mentioned w32time server settings applied by GPO, but I tested this early on and there were no settings applied to this service by gpo. Others said that the reporting software may not be picking up some old gpo settings applied. So I searched the registry for all w32time instaces. I came across an interesting key that indicated there may be some other ntp software running on the server. Sure enough, I look through the installed software list and there the little F*&%ER is. Uninstalled and now working like a dream. FFFFFFFUUUUUUUUUUUU

  • SmartOS reboots spontaneously

    - by Alex
    I run a SmartOS system on a Hetzner EX4S (Intel Core i7-2600, 32G RAM, 2x3Tb SATA HDD). There are six virtual machines on the host: [root@10-bf-48-7f-e7-03 ~]# vmadm list UUID TYPE RAM STATE ALIAS d2223467-bbe5-4b81-a9d1-439e9a66d43f KVM 512 running xxxx1 5f36358f-68fa-4351-b66f-830484b9a6ee KVM 1024 running xxxx2 d570e9ac-9eac-4e4f-8fda-2b1d721c8358 OS 1024 running xxxx3 ef88979e-fb7f-460c-bf56-905755e0a399 KVM 1024 running xxxx4 d8e06def-c9c9-4d17-b975-47dd4836f962 KVM 4096 running xxxx5 4b06fe88-db6e-4cf3-aadd-e1006ada7188 KVM 9216 running xxxx5 [root@10-bf-48-7f-e7-03 ~]# The host reboots several times a week with no crash dump in /var/crash and no messages in the /var/adm/messages log.

We do not have physical or virtual access to the server console - no KVM, no iLO or anything like this. So, the only way to debug is to analyze crash dumps/log files. I am not a SmartOS/Solaris expert so I am not sure how to proceed. Is there any equivalent of Linux netconsole for SmartOS? Can I just redirect the console output to the network port somehow? Maybe I am missing something obvious and crash information is located somewhere else.

  • All my sites are 403 but the server is running. Errors on startup

    - by Craig
    We gave access to a contractor to install a firewall and somehow while he was doing it he fracked something up. Everything went off-line about 24 hours ago and we are effectively out of business until I solve this and the person who messed up the thing is not returning calls. I found a few errors. First, I'm not a server guy - I can look at log files and normally everything runs fine. All 'services' are running according to 1and1 server monitoring and mail is being delivered just fine. The whole thing was off-line until I (probably stupidly) updated the kernel from 6.2 to 6.3 this morning and I got everything back except the http access. All the domains (~200 of them) are returning a 403 error and nothing is recorded in the access log. On every restart I see this error in the messages log file: init: Failed to spawn ttyS0 main process: unable to execute: No such file or directory and a little later these: kernel: WARNING: at kernel/sched.c:5914 thread_return+0x232/0x79d() (Not tainted) kernel: Hardware name: X9SCL/X9SCM kernel: Modules linked in: xt_iprange iptable_filter ip_tables ip6t_REJECT nf_conntrack_ipv6 nf_defrag_ipv6 xt_state nf_conntrack ip6table_filter ip6_tables ipv6 ext4 jbd2 serio_raw i2c_i801 i2c_core sg iTCO_wdt iTCO_vendor_support e1000e ext3 jbd mbcache raid1 sd_mod crc_t10dif ahci dm_mirror dm_region_hash dm_log dm_mod [last unloaded: scsi_wait_scan] kernel: Pid: 367, comm: md3_raid1 Not tainted 2.6.32-220.2.1.el6.x86_64 #1 kernel: Call Trace: kernel: [<ffffffff81069997>] ? warn_slowpath_common+0x87/0xc0 kernel: [<ffffffff810699ea>] ? warn_slowpath_null+0x1a/0x20 kernel: [<ffffffff814eccc5>] ? thread_return+0x232/0x79d kernel: [<ffffffff8126a4d9>] ? cpumask_next_and+0x29/0x50 kernel: [<ffffffff813e9c05>] ? md_super_wait+0x55/0x90 kernel: [<ffffffff81090a10>] ? autoremove_wake_function+0x0/0x40 kernel: [<ffffffff813ebf46>] ? md_update_sb+0x206/0x3f0 kernel: [<ffffffff813ee922>] ? md_check_recovery+0x3f2/0x6d0 kernel: [<ffffffffa005b129>] ? raid1d+0x49/0x1050 [raid1] kernel: [<ffffffff814ed985>] ? schedule_timeout+0x215/0x2e0 kernel: [<ffffffff814ef447>] ? _spin_unlock_irqrestore+0x17/0x20 kernel: [<ffffffff813eb336>] ? md_thread+0x116/0x150 kernel: [<ffffffff81090a10>] ? autoremove_wake_function+0x0/0x40 kernel: [<ffffffff813eb220>] ? md_thread+0x0/0x150 kernel: [<ffffffff810906a6>] ? kthread+0x96/0xa0 kernel: [<ffffffff8100c14a>] ? child_rip+0xa/0x20 kernel: [<ffffffff81090610>] ? kthread+0x0/0xa0 kernel: [<ffffffff8100c140>] ? child_rip+0x0/0x20 And something is wrong with the Named/BIND resulting in the same error for all domains: zone DOMAINEXAMPLE.com/IN: loading from master file DOMAINEXAMPLE.com failed: file not found zone DOMAINEXAMPLE.com/IN: not loaded due to errors. _default/DOMAINEXAMPLE.com/IN: file not found I'm pretty sure this is not enough information to solve the problem, but I'm willing to engage someone who can work this out for me. Any help would be greatly appreciated.

  • How to diagnose computer lockups and freezes?

    - by Scott Mitchell
    I built a desktop computer a couple years back with the following specs: CPU: Intel Core 2 Quad Q9300 Yorkfield 2.5GHz 6 MB L2 Cache LGA 775 95W Quad-Core Processor BX80580Q9300 Motherboard: EVGA 122-CK-NF68-T1 LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard Video Card: Two EVGA 256-P2-N758-TR GeForce 8600GT SCC 256 MB 128-bit GDDR3 PCI Express x16 SLI Supported Video Card PSU: SeaSonic S12 Energy Plus SS-550HT 550W ATX12V V2.3 / EPS12V V2.91 SLI Certified CrossFire Ready 80 PLUS Certified Active PFC Power Supply Memory: Two G.SKILL 4 GB (2 x 2 GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model F2-6400CL5D-4GBPQ Since its inception, the machine has periodically locked up, the regularity having varied over the years from once a day to once a month. Typically, lockups happen once every few days. By "lockup" I mean my computer just freezes. The screen locks up, I can't move the mouse. Hitting keys on my keyboard that normally turn LEDs on or off on the keyboard (such as Caps Lock) no longer turn the LEDs on or off. If there was music playing at the time of the lockup, noise keeps coming out of the speakers, but it's just the current frequency/note that plays indefinitely. There is no BSOD. When such a lockup occurs I have to do a hard reboot by either turning off the computer or hitting the reset button. I have the most recent version of the NVIDIA hardware drivers, and update them semi-regularly, but that hasn't seemed to help. I am currently using Windows 7 x64, but was previously using Windows Server 2003 x64 and having the same lockup issues. My guess is that it's somehow video driver or motherboard related, but I don't know how to go about diagnosing this problem to narrow down which of the two is the culprit. Additional information re: cooling Regarding cooling... I've not installed any after-market cooling systems aside from two regular fans I scavenged from an older computer. The fan atop the CPU is the one that shipped with it. One of the two scavenged fans I added it located at the bottom tower of the corner, in an attempt to create some airflow from front to back. The second fan is pointed directly at the two video cards. SpeedFan installation and readings Per studiohack's suggestion, I installed SpeedFan, which provided the following temperature readings: GPU: 63C GPU: 65C System: 76C CPU: 64C AUX: 36C Core 0: 78C Core 1: 76C Core 2: 79C Core 3: 79C Update #3: Another Lockup :-( Well, I had another lockup last night. :-( SpeedFan reported the CPU temp at 38 C when it happened, and there was no spike in temperature leading up to the freeze. One thing I notice is that the freeze seems more likely to happen if I am watching a video. In fact, of the last 5 freezes over the past month, 4 of them have been while watching a video on Flickr. Not necessarily the same video, but a video nevertheless. I don't know if this is just coincidence or if it means anything. (As an aside, each night before bedtime my 2 year old daughter sits on my lap and watches some home videos on Flickr and, in the last month, has learned the phrase, "Uh oh, computer broke.") Update #4: MemTest86 and 3DMark06 Test Results: Per suggestions in the comments, I ran the MemTest86 overnight and it cycled through the 8 GB of memory 5 times without error. I also ran the 3DMark06 test without a problem (see my scores at http://3dmark.com/3dm06/15163549). So... what now? :-) Any further suggestions on what to check? Is there some way to get a stack trace or something when the computer locks like that? Resolution I have never did figure out the particular problems, but based on the suggestions here and elsewhere, I'm presuming it was a motherboard issue. In any event, I recently upgraded my system, buying a new motherbeard, PSU, CPU, and RAM, and that new rig has been working splendidly the past several weeks. I am using the same graphic cards as in the old setup, so I think it's safe to reason that they weren't the cause of the problem.

  • FTP Upload works from local command line / remote GUI client but not from PHP script

    - by MrOodles
    I originally posted this question at StackOverflow, but I'm beginning to think it's more of a server question. I have installed ProFTPd on an EC2 instance running Ubuntu 10.10. I have managed my proftpd.conf file as well as my server permissions to be able to connect and upload/move files using FTP both remotely using Filezilla, and on the server itself when connecting to 127.0.0.1. The problem I'm running into is when I try to upload/install a file using Joomla's interface. I give Joomla the same login information that I give to Filezilla, and the connection is made in the same fashion. The ftp.log file actually shows that Joomla is able to login to the server: localhost UNKNOWN nobody [17/Jan/2011:14:09:17 +0000] "USER ftpuser" 331 - localhost UNKNOWN ftpuser [17/Jan/2011:14:09:17 +0000] "PASS (hidden)" 230 - localhost UNKNOWN ftpuser [17/Jan/2011:14:09:17 +0000] "PASV" 227 - localhost UNKNOWN ftpuser [17/Jan/2011:14:09:17 +0000] "TYPE I" 200 - localhost UNKNOWN ftpuser [17/Jan/2011:14:09:17 +0000] "STOR /directory/store/location/file.zip" 550 - But it fails when attempting the STOR command. I have traced the problem in the Joomla code to the PHP FTP module. The code (with my trace statements added): if (@ftp_put($this->_conn, $remote, $local, $mode) === false) { echo "\n FTP PUT failed."; echo "\n Remote: $remote ; Local: $local ; Mode: $mode - Either ASCII: ".FTP_ASCII." or Binary: ".FTP_BINARY; echo "\n The user: ".exec("whoami"); JError::raiseWarning('35', 'JFTP::store: Bad response' ); return false; } Trace ouputs: FTP PUT failed. Remote: /directory/store/location/file.zip ; Local: /tmp/phpwuccp4 ; Mode: 2 - Either ASCII: 1 or Binary: 2 The user: www-data And in case you were curious, here is an example of the FTP log when using Filezilla: my_client_ip UNKNOWN nobody [17/Jan/2011:16:45:55 +0000] "USER ftpuser" 331 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "PASS (hidden)" 230 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "OPTS UTF8 ON" - - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "PWD" 257 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "TYPE I" 200 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "PASV" 227 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:45:55 +0000] "MLSD" 226 3405 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:06 +0000] "CWD location" 250 3405 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:06 +0000] "PWD" 257 3405 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:06 +0000] "PASV" 227 3405 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:07 +0000] "MLSD" 226 3757 my_client_ip UNKNOWN nobody [17/Jan/2011:16:46:37 +0000] "USER ftpuser" 331 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "PASS (hidden)" 230 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "OPTS UTF8 ON" - - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "CWD /location" 250 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "PWD" 257 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "TYPE I" 200 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:37 +0000] "PASV" 227 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:39 +0000] "STOR file.zip" 226 125317 my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:39 +0000] "PASV" 227 - my_client_ip UNKNOWN ftpuser [17/Jan/2011:16:46:39 +0000] "MLSD" 226 497

  • Email forwarding from my domain to gmail - FAIL

    - by pitosalas
    [There are numerous similar questions on ServerFault but I couldn't find one that was exactly on point] Background: I use Gmail for my email client. My email is [email protected]. However the email that people communicate to me with is [email protected]. I run the server that hosts www.example.com and other domains, at ServerBeach. Up to yesterday, I had SENDMAIL painlessly just forward emails to [email protected] to [email protected] and everything was fine, for several years in fact. Suddenly my email stopped working - that is, my gmail account stopped receiving emails via the forward from my server. Looking into it I found a bunch of emails sitting on my server with content like this: ... while talking to gmail-smtp-in.l.google.com.: RCPT To: <<< 450-4.2.1 The user you are trying to contact is receiving mail at a rate that <<< 450-4.2.1 prevents additional messages from being delivered.

But I don't know really what's going on nor do I see whatever emails might be involved. I've read stuff on zoneedit.com that sounds like they might have a solution in their service for what I am trying to do. I also read a lot about admining DNS and SENDMAIL and tried various things, but nothing works. Can you tell from my description what is going on that caused GMail's server to stop accepting email from my server and is there a way to stop it? What is the 'correct' way to configure things so that emails to [email protected] behave as if they were sent to [email protected]? Thanks so much!

  • Installing .NET Framework 4 Client Profile breaks Windows Update

    - by Richard
    I have a Samsung NC-10 netbook with a fresh install of Windows 7 Home Premium 32-bit (it only had 2GB). If Microsoft .NET Framework 4 Client Profile is installed on it, Windows Update will always return error code 8024402F ("Windows Update encountered an unknown error"). As soon as I uninstall it, Windows Update works just fine again. Out of the four computers in this house, only this netbook has the problem. My question is: How can I get the .NET Framework 4 Client Profile installed on my netbook and continue to have a functioning Windows Update? ----- More information ----- The hard-drive recently died on my netbook so I replaced it with a nice new SSD and did a fresh installation of Windows 7 Home Premium (SP1) - along with all the updates. At some point I found that, when I ran Windows Update, I was greeted with error code 8024402F ("Windows Update encountered an unknown error"). Looking in C:\Windows\WindowsUpdate.log, I saw the following issue: WARNING: ECP: Failed to validate cab file digest downloaded from http://download.windowsupdate.com/msdownload/update/software/dflt/2012/02/4913552_4a5c9563d1f58c77f30d0d5c9999e4b8bff3ab21.cab with error 0x80091007 WARNING: ECP: This roundtrip contained some optimized updates which failed. New Update count = 0, Old Count = 3 FATAL: ProcessCoreMetadata did not return any update to be committed WARNING: Sync of Updates: 0x8024402f WARNING: SyncServerUpdatesInternal failed: 0x8024402f When I downloaded the CAB from the URL listed and opened it, it contained a file called 4913552.txt. A search on Google suggested that it's related to Microsoft .NET Framework 4 Client Profile. Other people had reported problems with it breaking Windows Update, but they were running Windows XP. I tried the steps outlined on the Microsoft site for this error code, but it reported that there was nothing wrong. I also found this superuser question, I tried all the answers listed but none of them made any difference. My router doesn't block ActiveX, changing my internet settings in IE made no difference, assuming it was a corrupted update repository didn't do anything (except wipe my update history), my date and time was correct, switching to Google's DNS didn't work and neither did disabling IPv6. Figuring that this update was corrupted, I repaired it and nothing changed. In desperation I un-installed it and Windows Update started working again! Brilliant! I then downloaded the full version from the Microsoft website, installed it and, thankfully, Windows Update continued to work just fine. A week later I turn on my netbook and Windows Update is broken again with exactly the same error message and log entries as before. Repairing .NET Framework 4 Client Profile did nothing, removing it entirely solved the problem again. Thinking this might be some odd Windows installation issue, I formatted the hard-drive and re-installed Windows. Same problem as before - as soon as .NET Framework 4 Client Profile ended up on the netbook, Windows Update stopped working and reported error 8024402F. As soon as it was un-installed, everything worked just fine again. There are three other machines in this house and all of them have working Windows Update and this Client Profile. Does anyone know why it causes this netbook to break and, more importantly, how I can fix it?
