• High load on X3220 Quad Core Linux Apache server

  - by John Templar

  I'm seriously in need of help. My sites are now nearly impossible to use because of massive loads on my server. I'm already a month late on my mortgage and this really isn't helping my situation. I've been working on fixing this intermittent load problem for months (never this bad). I'm suspecting some kind of attack since I'm under DDOS attack a lot! I've been trying to figure out what is causing the load but I'm afraid I just don't have the experience or knowledge to understand all the data I've been looking at. I don't even know where to begin or how to test for the large array of attacks out there. Here's some data you might find useful... Server: Xeon X3220 Quad Core 2.4 GHz - Linux, FreeBSD 500 GB HD and 8 Gig of Ram. Runs Centos release 5.7 Server Version: Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 mod_qos/9.74 Warning: All sites are softcore adult sites - mostly fantasy art like elves and amazons. 1) Sites may run fine for weeks or just days at less than 10 load then start jumping to 40-80 load - no idea why. Same sites, same mods, same amount of traffic - just WHAM! 2) I get an email almost every day that says: "Large Number of Failed Login Attempts from IP (different each time)". My webhost (who almost never helps me) told me it was a udp flood or something. 3) I've changed the port for MySQL from the default. If I ever put it back to the default - I get Loads of over 100 from what must be a constant mysql port flood. 4) I've reconfigured MYSQL. Link: http://www.deadlyamazons.com/logs/mycnf.txt 5) I have 3 Joomla Jomsocial networks. I've spent a couple weeks turning all the mods/plugins off, waiting a day and then turning them back on the next day or later if there isn't any change (there hasn't been). For example, on Thursday I'll turn off videos, on Friday I'll turn off chat.. etc and nothing changes the load appreciably. 6) Joomla info: All SEF turned off - sh404sef completely disabled and removed. Components: Joomla 1.5.22, Jomsocial 2.0.5, Kunena 1/31/2011, HWDMediashare 11/22/2010 and JBolo Chat 2.7.3, Comet Chat or Envolve Chat. Page Compression is on, Cache is on 15 mins. Please click on this forum to see links to all my reports: http://forum.joomla.org/viewtopic.php?f=433&t=706035&p=2777500#p2777500 Any help would be highly appreciated.

• VBA + Polymorphism: Override worksheet functions from 3rd party

  - by phi

  my company makes extensive use of a data provider using a (closed source) VBA plugin. In principal, every query follows follows a certain structure: Fill one cell with a formula, where arguments to the formula specify the query the range of that formula is extended (not an arrray formula!) and cells below/right are filled with data For this to work, however, a user has to have a terminal program installed on the machine, as well as a com-plugin referenced in VBA/Excel. My Problem These Excelsheets are used and extended by multiple users, and not all of them have access to the data provider. While they can open the sheet, it will recalculate and the data will be gone. However, frequent recalculation is required. I would like every user to be able to use the sheets, without executing a very specific set of formulas. Attempts remove the reference on those computers where I do not have terminal access. This generates a NAME error i the cell containing the query (acceptable), but this query overrides parts of the data (not acceptable) If you allow the program to refresh, all data will be gone after a failed query Replace all formulas with the plain-text result in the respective cells (press a button and loop over every cell...). Obviously destroys any refresh-capabilities the querys offer for all subsequent users, so pretty bad, too. A theoretical idea, and I'm not sure how to implement it: Replace the functions offered by the plugin with something that will be called either first (and relay the query through to the original function, if thats available) or instead of the original function (by only deploying the solution on non-terminal machines), which just returns the original value. More specifically, if my query function is used like this: =GETALLDATA(Startdate, Enddate, Stockticker, etc) I would like to transparently swap the function behind the call. Do you see any hope, or am I lost? I appreciate your help. PS: Of course I'm talking about Bloomberg... Some additional points to clarify issues raise by Frank: The formula in the sheets may not be changed. This is mission-critical software, and its way too complex for any sane person to try and touch it. Only excel and VBA may be used (which is the reason for the previous point...) It would be sufficient to prevent execution of these few specific formulas/functions on a specific machine for all excel sheets to come This looks more and more like a problem for stackoverflow ;-)

• Ubuntu 12.04 crash analysis - strange binary data on all open files at the moment of crash

  - by lanbo

  A couple of hours ago we got a system crash on Ubuntu 12.04. We checked all the log files and there is nothing suspicious to blame to. Last stuff that was logged was some dovecot activity. There are no kernel panic messages. Nothing. It is a new server (new hardware) we are testing before production. And because it is new hard, I'm suspicious the problem may be due to some faulty hardware. We already run memtester with no problem detected. I'll be happy to hear from other hardware testing tools (the machine has SSD). Anyway, the thing I wanted to ask you is a different one. The strange thing is on every open file at the moment of the crash we found the next sequence of symbols was written into them: "@^@^@^@^@^@^@...". For example, on the syslog log file we got: Apr 16 15:53:56 odyssey dovecot: pop3-login: Aborted login (auth failed, 1 attempts): user=<info>, method=PLAIN, rip=46.29.255.73, lip=5.9.58.177 ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^ [these continues for about 1000 chars...] ^@^@^@^@Apr 16 15:55:12 odyssey kernel: imklog 5.8.6, log source = /proc/kmsg started. We got all these symbols in all open files. These include: syslog, mail.log, kern.log, ... But also on some logs that are output by php scripts run in CRONs from user accounts (not root). So, any idea why all open files got these characters written during the crash? This is pretty bad since the crash corrupted many files (we don't even know which other ones may be affected). We are suspicious that all open files (in write mode maybe) at the moment of the crash got all these symbols inserted. Why is that? BTW [in case it helps], the system automatically rebooted after the crash but Apache did not start. There were not traces in /var/apache2/*log why apache did not start. After running a "service apache2 start" it started with no problems. Also, we rebooted the machine manually and Apache also started on reboot. But it did not start after the crash and no errors were reported. Thanks guys!

• Active Directory Corrupted In Windows Small Business Server 2011 - Server No Longer Domain Controller

  - by ThinkerIV

  I have a rather bad problem with my Windows SBS 2011. First of all, I'll give the background to what caused the problem. I was setting up a new small business server network. I had my job about finished. The server was working great, all the workstations had joined the domain, and I had all my applications and data moved to the server. I thought I was done. But then it happened. I tried adding one more computer to the domain, and to my dismay the computer name was set to the same name as the server. Apparently when a computer joins a domain with the same name as another machine that is already on the domain, it overrides the first one. For normal workstations, this is not a big deal, you just delete the computer from AD and rejoin the original computer to the domain. However, for a server that is the domain controller it is a whole different story. Since the server got overridden in AD, it is no longer the domain controller. The DNS service is not working and all kinds of other services are failing also. So the question is, what are my options? I am embarrassed to admit it, but since this is a new server one thing I did not have setup yet was backup. So I have no backups to work from. I am worried that things are broken enough that I might need to do a reinstall. However, I already have several days worth of configuration into this server, so I would obviously prefer if there was a fix that would prevent me from needing to do a reinstall. All the server components are there and installed correctly, but they are misconfigured (I think it is basically just Active Directory). So I have the feeling that if I did the right thing I could solve the issue without a reinstall. Is there anyway to rerun the component that installs the initial configuration to "convert" the base windows server 2008 r2 install into a SBS? In other words in the program files folder there is an application called SBSsetup.exe, is there anyway to rerun this and have it reconfigure AD, etc. to work with SBS? Any insight will be greatly appreciated. Thanks.

• OS X server large scale storage and backup

  - by user135217

  I really hope this question doesn't come across as trolling or asking for buying advice. It's not intended. I've just started working for a small ad agency (40 employees). I actually quit being a system administrator a few years ago (too stressful!), but the company we're currently outsourcing our IT stuff to is doing such a bad job that I've felt compelled to get involved and do what I can to improve things. At the moment, all the company's data is stored on an 8TB external firewire drive attached to a Mac Mini running OS X Server 10.6, which provides filesharing (using AFP) for the whole company. There is a single backup drive, which is actually a caddy containing two 3TB hard drives arranged in RAID 0 (arrggghhhh!), which someone brings in as and when and copies over all the data using Carbon Copy Cloner. That's the entirety of the infrastructure, and the whole backup and restore strategy. I've been having sleepless nights. I've just started augmenting the backup process with FreeBSD, ZFS, sparse bundles and snapshot sends to get everything offsite. I think this is a workable behind the scenes solution, but for people's day to day use I'm struggling. Given the quantity and importance of the data, I think we should really be looking towards enterprise level storage solutions, high availability and so on, but the whole company is all Mac all the time, and I cannot find equipment that will do what we need. No more Xserve; no rack storage; no large scale storage at all apart from that Pegasus R6 that doesn't seem all that great; the Mac Pro has fibre channel, but it's not a real server and it's ludicrously expensive; Xsan looks like it's on the way out; things like heartbeatd and failoverd have apparently been removed from Lion Server; the new Mac Mini only has thunderbolt which severely limits our choices; the list goes on and on. I'm really, really not trying to troll here. I love Macs, but I just genuinely don't know where I'm supposed to look for server stuff. I have considered Linux or FreeBSD and netatalk for serving files with all the server-y goodness those OSes bring, but some the things I've read make me wonder if it's really the way to go. Also, in my own (admittedly quite cursory) experiments with it, I've struggled to get decent transfer speeds. I guess there's also the possibility of switching everyone off AFP and making them use SMB or NFS, but I understand that this can cause big problems with resource forks and file locks. I figure there must be plenty of all Mac companies out there. If you're the sysadmin at one, what do you use? Any suggestions very gratefully received.

• How to keep group-writeable shares on Samba with OSX clients?

  - by Oliver Salzburg

  I have a FreeNAS server on a network with OSX and Windows clients. When the OSX clients interact with SMB/CIFS shares on the server, they are causing permission problems for all other clients. Update: I can no longer verify any answers because we abandoned the project, but feel free to post any help for future visitors. The details of this behavior seem to also be dependent on the version of OSX the client is running. For this question, let's assume a client running 10.8.2. When I mount the CIFS share on an OSX client and create a new directory on it, the directory will be created with drwxr-x-rx permissions. This is undesirable because it will not allow anyone but me to write to the directory. There are other users in my group which should have write permissions as well. This behavior happens even though the following settings are present in smb.conf on the server: [global] create mask= 0666 directory mask= 0777 [share] force directory mode= 0775 force create mode= 0660 I was under the impression that these settings should make sure that directories are at least created with rwxrwxr-x permissions. But, I guess, that doesn't stop the client from changing the permissions after creating the directory. When I create a folder on the same share from a Windows client, the new folder will have the desired access permissions (rwxrwxrwx), so I'm currently assuming that the problem lies with the OSX client. I guess this wouldn't be such an issue if you could easily change the permissions of the directories you've created, but you can't. When opening the directory info in Finder, I get the old "You have custom access" notice with no ability to make any changes. I'm assuming that this is caused because we're using Windows ACLs on the share, but that's just a wild guess. Changing the write permissions for the group through the terminal works fine, but this is unpractical for the deployment and unreasonable to expect from anyone to do. This is the complete smb.conf: [global] encrypt passwords = yes dns proxy = no strict locking = no read raw = yes write raw = yes oplocks = yes max xmit = 65535 deadtime = 15 display charset = LOCALE max log size = 10 syslog only = yes syslog = 1 load printers = no printing = bsd printcap name = /dev/null disable spoolss = yes smb passwd file = /var/etc/private/smbpasswd private dir = /var/etc/private getwd cache = yes guest account = nobody map to guest = Bad Password obey pam restrictions = Yes # NOTE: read smb.conf. directory name cache size = 0 max protocol = SMB2 netbios name = freenas workgroup = COMPANY server string = FreeNAS Server store dos attributes = yes hostname lookups = yes security = user passdb backend = ldapsam:ldap://ldap.company.local ldap admin dn = cn=admin,dc=company,dc=local ldap suffix = dc=company,dc=local ldap user suffix = ou=Users ldap group suffix = ou=Groups ldap machine suffix = ou=Computers ldap ssl = off ldap replication sleep = 1000 ldap passwd sync = yes #ldap debug level = 1 #ldap debug threshold = 1 ldapsam:trusted = yes idmap uid = 10000-39999 idmap gid = 10000-39999 create mask = 0666 directory mask = 0777 client ntlmv2 auth = yes dos charset = CP437 unix charset = UTF-8 log level = 1 [share] path = /mnt/zfs0 printable = no veto files = /.snap/.windows/.zfs/ writeable = yes browseable = yes inherit owner = no inherit permissions = no vfs objects = zfsacl guest ok = no inherit acls = Yes map archive = No map readonly = no nfs4:mode = special nfs4:acedup = merge nfs4:chown = yes hide dot files force directory mode = 0775 force create mode = 0660

• DVD playback with Windows Media Player 11 works fine, but when copied to HDD and then played back, t

  - by stakx

  I have several DVDs with short documentaries on it. Since the notebook I'm using (a Dell Latitude E6400) has only one DVD drive, and I might play back those short movies very often, I thought of copying them to the HDD and playing them back from there. However, I've run into a problem, namely stuttering audio. Problem description: When I play back these movies directly from DVD (with Windows Media Player 11 under Windows Vista), everything works fine. Smooth video, no significant audio problems (only the occasional click). But as soon as I copy any of these DVDs to the HDD and try to play them back from there (e.g. using the wmpdvd://drive/title/chapter?contentdir=path protocol, I get stuttering audio — audio playback sounds like a machine gun for a third of a second or so, approx. every 8 seconds. I have tried converting the VOB files from the DVD to another format (ie. ripping), but that resulted in a noticeable downgrade of picture quality. Therefore I thought it best to keep the files in their original format, if possible. Still, I suspect that the stuttering audio is due to some (de-)muxing problem, and that changing the file format might help. (After all, video playback is fine; therefore I don't think that the hardware is too slow for playback.) Only thing is, I don't know how to convert the VOB files to another Windows Media Player-compatible format without quality loss. I hope someone can help me, or give me further pointers on things I could try out to get HDD playback to work without the problem described. Some things I've tried so far, without any success: VOB2MPG, in order to convert the .vob file to a .mpg file. But that changes only the A/V container, not the content. No re-encoding takes place at all. Re-encoding with MPlayer/MEncoder. Lots of quality loss there, and I frankly haven't got the time to test all possible settings combinations available. Disabling all plug-ins, equalizers, etc. in Windows Media Player. Disabling all hardware acceleration on the audio playback device. Further info on the VOB files I'm trying to playback: The video format is MPEG ES, PAL 720x576 pixels @ 24/25 frames per second. The sound stream is uncompressed PCM, 16-bit stereo @ 48kHz. (Might it help if I somehow re-encoded the sound stream at a lower resolution, or as an MP3? If so, how would I do this without changing the video stream?) P.S.: I am limited to using Windows Media Player (11). (I previously tried MPlayer btw., but the video playback quality was surprisingly bad.)

• Hot-swap drive got new name, can I change it on-the-fly?

  - by T.J. Crowder

  One of the HDDs in my server's RAID config failed, so I took it out of the array and had the data center hot-swap it. They've done that, but now the new drive is /dev/sdc rather than /dev/sda. I suspect — correct me if I'm wrong — that if I reboot the server, it will be /dev/sda again, so I'm hesitant to add it back to the array as /dev/sdc because I don't want to lay a trap for myself to fall into on the next reboot. I'd just as soon not reboot the server if I don't need to (if I do need to, well, too bad for me). Is there a way I can change the device name from /dev/sdc to /dev/sda without rebooting? This is on Ubuntu 10.04 LTS. It's an md array ("Linux Software RAID"), where currently one of the devices (there are a couple of them) looks like this ("degraded" because I've removed the old /dev/sda from it): # mdadm --detail /dev/md0 /dev/md0: Version : 00.90.03 Creation Time : Sun Oct 11 21:07:54 2009 Raid Level : raid1 Array Size : 97536 (95.27 MiB 99.88 MB) Used Dev Size : 97536 (95.27 MiB 99.88 MB) Raid Devices : 2 Total Devices : 1 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Thu Jun 30 09:31:16 2011 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 UUID : 496be7a5:ab9177ed:7792c71e:7dc17aa4 Events : 0.112 Number Major Minor RaidDevice State 0 8 17 0 active sync /dev/sdb1 1 0 0 1 removed Thanks, Update: Reading through the kernel md documentation, I suspect that if the name changes on reboot, it won't matter. (Good design, that.) Here's why: Boot time autodetection of RAID arrays When md is compiled into the kernel (not as module), partitions of type 0xfd are scanned and automatically assembled into RAID arrays. This autodetection may be suppressed with the kernel parameter "raid=noautodetect". As of kernel 2.6.9, only drives with a type 0 superblock can be autodetected and run at boot time. The kernel parameter "raid=partitionable" (or "raid=part") means that all auto-detected arrays are assembled as partitionable. I do have md compiled into the kernel, so I'm rebuilding the array now and will do the reboot to see what happens. Even if it works, the above doesn't answer the question I actually asked, so unless someone comes along and answers that question in the meantime (I'd be interested, even if it's not necessary for what I'm doing this very moment), I'll just delete the question to keep noise down.

• Nginx Proxying to Multiple IP Addresses for CMS' Website Preview

  - by Matthew Borgman

  First-time poster, so bear with me. I'm relatively new to Nginx, but have managed to figure out what I've needed... until now. Nginx v1.0.15 is proxying to PHP-FPM v.5.3.10, which is listening at http://127.0.0.1:9000. [Knock on wood] everything has been running smoothly in terms of hosting our CMS and many websites. Now, we've developed our CMS and configured Nginx such that each supported website has a preview URL (e.g. http://[WebsiteID].ourcms.com/) where the site can be, you guessed it, previewed in those situations where DNS doesn't yet resolve to our server, etc. Specifically, we use Nginx's Map module (http://wiki.nginx.org/HttpMapModule) and a regular expression in the server_name of the CMS' server{ } block to 1) lookup a website's primary domain name from its preview URL and then 2) forward the request to the "matched" primary domain. The corresponding Nginx configuration: map $host $h { 123.ourcms.com www.example1.com; 456.ourcms.com www.example2.com; 789.ourcms.com www.example3.com; } and server { listen [OurCMSIPAddress]:80; listen [OurCMSIPAddress]:443 ssl; root /var/www/ourcms.com; server_name ~^(.*)\.ourcms\.com$; ssl_certificate /etc/nginx/conf.d/ourcms.com.chained.crt; ssl_certificate_key /etc/nginx/conf.d/ourcms.com.key; location / { proxy_pass http://127.0.0.1/; proxy_set_header Host $h; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } } (Note: I do realize that the regex in the server_name should be "tighter" for security reasons and match only the format of the website ID (i.e. a UUID in our case).) This configuration works for 99% of our sites... except those that have a dedicated IP address for an installed SSL certificate. A "502 Bad Gateway" is returned for these and I'm unsure as to why. This is how I think the current configuration works for any requests that match the regex (e.g. http://123.ourcms.com/): Nginx looks up the website's primary domain from the mapping, and as a result of the proxy_pass http://127.0.0.1 directive, passes the request back to Nginx itself, which since the proxied request has a hostname corresponding to the website's primary domain name, via the proxy_set_header Host $h directive, Nginx handles the request as if it was as direct request for that hostname. Please correct me if I'm wrong in this understanding. Should I be proxying to those website's dedicated IP addresses? I tried this, but it didn't seem to work? Is there a setting in the Proxy module that I'm missing? Thanks for the help. MB

• Error: Multilib version problems found

  - by Kovács Ákos

  What causes this error? Error: Multilib version problems found. This often means that the root cause is something else and multilib version checking is just pointing out that there is a problem. Eg.: 1. You have an upgrade for glibc which is missing some dependency that another package requires. Yum is trying to solve this by installing an older version of glibc of the different architecture. If you exclude the bad architecture yum will tell you what the root cause is (which package requires what). You can try redoing the upgrade with --exclude glibc.otherarch ... this should give you an error message showing the root cause of the problem. 2. You have multiple architectures of glibc installed, but yum can only see an upgrade for one of those arcitectures.

• Hard freeze on new computer

  - by mphair

  OCZ Gold 3x2GB 240-Pin DDR3 SDRAM PC312800 Palit NE5T240SFHD01 GeForce GT240 1GB 128-bit GDDR5 ASUS P7P55D-E LGA 1156 P55 SATA 6Gb/s USB 3.0 ATX Intel Motherboard Intel Core i7-860 Lynnfield 2.8GHz 8MB L3 Cache LGA 1156 95W Quad-Core Processor SAMSUNG 22X Optical drive (DVD+-R/RW) CORSAIR CMPSU-620HX 620W ATX12V V2.2 Windows 7 Ultimate x64 Brand new system (got it from newegg two days ago) and it booted up and installed windows and ran for a day just fine. Yesterday, I boot it up in the afternoon and run various games at full graphics for most of the day. I turn on WoW and play for a few hours and it hard stalls. No numlock switching, no mouse feedback but nothing going wrong on the screen. No BSOD. I wait a bit to see if the stall is just a temporary one, but then force shutdown the computer. Upon reboot, everything seems fine, windows sees that it didn't shut down properly but I go into normal boot and restart WoW. I'm able to load it up and start running around when it freezes again. This time when I restart, it doesn't even get to BIOS. It starts (power goes on) and it just hangs with no output to the monitors. I shut it off and went to bed. This morning, I turned it on and went into BIOS setup. I'm not terribly experienced with messing with BIOS settings but I checked over them the best I could. Everything seems fine so I boot into windows and browse the internet for a bit looking for a solution, hard freeze within 10 minutes. I restart and go into BIOS and check the CPU temperature, 40c. I'm kinda stumped here. Some people say it might be a memory issue, but why would it take so long for it to come up? Could it have been slowly accessing one memory stick at a time and then it just got to a bad one and that's what is causing it to fail? It seems odd that I don't get a BSOD from a hardware failure. Having the screen just halt with no input or output change seems like a software thing to me. Any thoughts?

• Looking for Fiddler2 help. connection to gateway refused...just got rid of a virus?

  - by john mackey

  I use Fiddler2 for facebook game items, and it's been a great success. I accessed a website to download some dat files I needed. I think it was eshare, ziddu or megaupload, one of those. Anyway, even before the rar file had downloaded, I got this weird green shield in the bottom right hand corner of my computer. It said a Trojan was trying to access my computer, or something to that extent. It prompted me to click the shield to begin anti-virus scanning. It turns out this rogue program is called Antivirus System Pro and is pretty hard to get rid of. After discovering the rogue program, I tried using Fiddler and got the following error: [Fiddler] Connection to Gateway failed. Exception Text: No connection could be made because the target machine actively refused it 127.0.0.1:5555 I ended up purchasing SpyDoctor + Antivirus, which I'm told is designed specifically for getting rid of these types of programs. Anyway, I did a quick-scan last night with spydoctor and malware bytes. Malware picked up 2 files, and Spydoctor found 4. Most were insignificant, but it did find a worm called Worm.Alcra.F, which was labeled high-priority. I don’t know if that’s the Anti-Virus Pro or not, but SpyDoctor said it got rid of all of those successfully. I tried to run Fiddler again before leaving home, but was still getting the "gateway failed" error. Im using the newest version of firefox. When I initially set up the Fiddler 2.2.8.6, I couldn’t get it to run at first, so I found this faq on the internet that said I needed to go through ToolsOptionsSettings and set up an HTTP Proxy to 127.0.0.1 and my Port to 8888. Once I set that up and downloaded this fiddler helper as a firefox add-on, it worked fine. When I turn on fiddler, it automatically takes my proxy setting from no proxy (default) to the 127.0.0.1 with Port 8888 set up. It worked fine until my computer detected this virus. Anyway, hopefully I've given you sufficient information to offer me your best advice here. Like I said, Spydoctor says the bad stuff is gone, so maybe the rogue program made some type of change in my fiddler that I could just reset or uncheck or something like that? Or will I need to completely remove fiddler and those dat files and rar files I downloaded? Any help would be greatly appreciated. Thanks for your time.

• In search of a good audio player for Ubuntu 9.10

  - by Joe Casadonte

  If this should be marked Community Wiki, please let me know. I'm switching from XP to Ubuntu, and I have been very disappointed with the selection of media players available. I'm primarily interested in an audio player, but integrated video and library management is OK, too. My criteria: Must be able to play audio CDs (I'm shocked how many apps this does away with, right away) Must be able to play MP3 & WAV; OGG, SHN, FLAC are all bonuses Repeat and Shuffle modes are a must FreeDB / GraceNote through a proxy is a must (if it can read a PAC file, that would be awesome) It needs to be really small, e.g. skinnable or an applet Ability to execute a playlist is a plus Gapless MP3 playback a plus I'm running Gnome, but I'm not totally adverse to a KDE app. Command-line only is also a viable option. Some that I've tried: RhythmBox - probably the best of the lot that I've tried; I don't like its mini mode (doesn't show the song being played) and I can't figure out how to get it to hit FreeDB/GraceNote through a proxy Songbird - can't play CDs, playlist management is atrocious Banshee Jajuk Maybe a couple of more. Thanks! UPDATE I tried out VLC, Amarok and Songbord (again). VLC I eventually got to work (I had some kind of bad configuration). It seemed way more involved than I was looking for out of a music player, and in general more geared to video than audio. I couldn't fathom its library management, which I think it has; maybe it doesn't, and that's why I couldn't figure it out. Amaork looked very promising but the library management was not to my liking, and the way it handled a playlist with both MP3 and WAV is inexplicable at best. I did like some aspects of the UI, but not enough to keep it. Songbird is very finicky, but I like the library management. Sort of. It kept telling me my Watch folder was invalid, even thought it clearly was accessible. Playlist management is bizarre, and the message that it was deleting source files whenever I deleted a playlist had me too worried to keep using it. Had it been able to play CDs, maybe I would have persevered. Audacious, while a bit odd at times, does seem to do what I want. If it had a library manager, I wouldn't have bothered trying any of the others. Thanks for the help, everyone!

• Dell PowerEdge R720 - Corrupted RAID

  - by BT643

  Apologies in advance for the lengthy question. We have a Dell PowerEdge R720 server with: 2 x 136GB SAS drives in RAID 1 for the OS (Ubuntu Server 12.04) 6 x 3TB SATA drives in RAID 5 for data A few days ago we were getting errors when trying to access files on the large RAID 5 partition. We rebooted the server and got a message about the raid controller has found a foriegn config. We've had this before, and just needed to use Dell's RAID configuration utility to import foreign config on the RAID. Last time this worked, but this time, it started doing a disk check then we got this: FSCK has returned the following: "/dev/sdb1 inode 364738 has a bad extended attribute block 7 /dev/sdb1 unexpected inconsistency run fsck manually (i.e without -a or -p options) MOUNTALL fsck /ourdatapartition [1019] terminated with status 4 MOUNTALL filesystem has errors /ourdatapartition errors where found while checking the disk drive for /ourdatapartition Press F to fix errors, I to Ignore or M for Manual Recovery" We pressed F to try and fix the errors, but it eventually errored with: Inode 275841084, i_blocks is 167080, should be 0.

We replaced the drive with a spare, and tried "F" to repair it again, but we keep just getting the same error as above. In the RAID configuration utility, all drives show as "online" and "optimal". We do have this data on another replicated server, so we're not worried about "recovering" anything, we just want to get the system back online asap. The server has 64 or 32GB memory, can't remember off the top of my head, but either way, with a 14TB RAID, I think it may still not be enough. Thanks EDIT - I checked the memory usage while fsck was running as suggested and after 2 or 3 minutes, it looked like this, using up nearly all of our servers memory: When it failed after 5 minutes or so with the error in my post, the memory immediately freed up again:

• Why can't I connect to remote Microsoft SQL Server through SSH tunnel?

  - by Alexander

  I have at home a D-Link DIR-615 C1 router with DD-WRT. I set up the SSH server on the router, and log on through an SSH2-RSA passphrase-protected key. That router is the gateway between the local network and the internet. One of the computers on that network has Microsoft SQL Server 2008 installed, with TCP/IP protocol enabled through port 1433. I've set up port forwarding on the router, so that remote connections are possible and are, in fact, working (some developers log on remotely without problems). I am part of another network, that has internet access through a proxy server, which only has ports 80 and 443 opened. I can't connect to that MSSQL server on that remote server because 1433 port is closed on this network. I connected (using Putty) through 443 port to my router's SSH server, and set up 2 tunnels. One is for RDP (3389), and it's working. The other is for 1433 port, to connect to the server. I can't connect through the SSH tunnel to the MS SQL Server, neither through telnet, or through GUI clients. Am I missing something? Additional details: on connect, I get this error from SQL Server Management Studio: TITLE: Connect to Server Cannot connect to localhost:14330. ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 3) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=3&LinkId=20476 BUTTONS: OK The tunnel is configured like this: L14330 192.168.0.103:1433 192.168.0.103 is the permanent address of the SQL Server on the LAN. I also successfully forwarded TCP traffic of 3389 port to that IP, so tunneling is working to that IP address. When connecting without tunnel, through Microsoft SQL Server Management Studio, using the same method the connection establishes. Too bad my proxy doesn't allow 1433 port traffic, I wouldn't have this headache.

• How can I change how OS X's 'say' command pronounces a word?

  - by jwhitlock

  OS X's say command is useful for some tasks (such as Skype's 'notify me when a contact comes online), but it is pronouncing some names incorrectly. Is there a way to teach say to pronounce a word differently? For example, try: say "Hi, Joel Spolsky" The 'ol' sounds like 'ball' rather than 'old'. I'd like to add an exception that say "Pronounce Spolsky like this", rather than try to teach new linguistic rules. I bet there is a way since it can pronounce "iphone" as Apple wants. Update - After some research, here's what I've learned: Text-to-speech is split between turning the text to phonemes, and then the phonemes are turned into audio using a voice. Changing the voice doesn't effect the phonemes. The Speech Synthesis Manager has some functions for turning text to phonemes, and a method for registering a speech dictionary that will add new text-phoneme maps. However, Apple's speech dictionary must be in a binary form - I didn't find any plist XML. Using dtrace while running say, I found some interesting files opened in /System/Library/PrivateFrameworks/SpeechDictionary.framework/Resources. This is probably the speech dictionary, but they are all binary, except for Homophones, which is XML. Adding entries to Homophones does nothing - it is probably used in speech-to-text. They are also code signed by Apple - changing them may prevent some programs from working. PrefixDictionary CartNames CartLite SymbolDictionary Homophones There are ways to add text versions of application interface elements so VoiceOver works, a lot of which a developer gets for free, but there are tricky bits. The standard here appears to be to use a phonetic spelling as needed. My guesses are: say is a light layer of code on top of the Speech Synthesis Manager. It would be easy for the Apple devs to add a command line option to take the path to a speech dictionary plist for alternate phoneme mapping, but they didn't. It may be a useful open-source project to write a better say. Skype probably uses Speech Synthesis Manager directly, leaving no hooks to change the way my friend's names are pronounced, other than spelling them phonetically, which is silly. The easiest way to make a command line version of say is how JRobert suggested. Here's my quick implementation, using Doug Harris's spelling suggestion: #!/bin/sh echo $@ | tr '[A-Z]' '[a-z]' | sed "s/spolsky/spowlsky/g" | /usr/bin/say Finally, some fun command line stuff: # Apple is weird sqlite3 /System/Library/PrivateFrameworks/SpeechDictionary.framework/Resources/Tuples .dump # Get too much information about what files are being opened sudo dtrace -n 'syscall::open*:entry { printf("%s %s",execname,copyinstr(arg0)); }' # Just fun say -v bad "Joel Spolsky Spolsky Spolsky Spolsky Spolsky, Joel Spolsky Spolsky Spolsky Spolsky Spolsky" echo "scale=1000; 4*a(1)" | bc -l | say

• SQL Clustering on Hyper V - is a cluster within a cluster a benefit.

  - by Chris W

  This is a re-hash of a question I asked a while back - after a consultant has come in firing ideas in to other teams in the department the whole issue has been raised again hence I'm looking for more detailed answers. We're intending to set-up a multi-instance SQL Cluster across a number of physical blades which will run a variety of different systems across each SQL instance. In general use there will be one virtual SQL instance running on each VM host. Again, in general operation each VM host will run on a dedicated underlying blade. The set-up should give us lots of flexibility for maintenance of any individual VM or underlying blade with all the SQL instances able to fail over as required. My original plan had been to do the following: Install 2008 R2 on each blade Add Hyper V to each blade Install a 2008 R2 VM to each blade Within the VMs - create a failover cluster and then install SQL Server clustering. The consultant has suggested that we instead do the following: Install 2008 R2 on each blade Add Hyper V to each blade Install a 2008 R2 VM to each blade Create a cluster on the HOST machines which will host all the VMs. Within the VMs - create a failover cluster and then install SQL Server clustering. The big difference is the addition of step 4 whereby we cluster all of the guest VMs as well. The argument is that it improves maintenance further since we have no ties at all between the SQL cluster and physical hardware. We can in theory live migrate the guest VMs around the hosts without affecting the SQL cluster at all so we for routine maintenance physical blades we move the SQL cluster around without interruption and without needing to failover. It sounds like a nice idea but I've not come across anything on the internet where people say they've done this and it works OK. Can I actually do the live migrations of the guests without the SQL Cluster hosted within them getting upset? Does anyone have any experience of this set up, good or bad? Are there some pros and cons that I've not considered? I appreciate that mirroring is also a valuable option to consider - in this case we're favouring clustering since it will do the whole of each instance and we have a good number of databases. Some DBs are for lumbering 3rd party systems that may not even work kindly with mirroring (and my understanding of clustering is that fail overs are completely transparent to the clients). Thanks.

• "log on as a batch job" user rights removed by what GPO?

  - by LarsH

  I am not much of a server administrator, but get my feet wet when I have to. Right now I'm running some COTS software on a Windows 2008 Server machine. The software installer creates a few user accounts for running its processes, and then gives those users the right to "log on as a batch job". Every so often (e.g. yesterday at 2:52pm and this morning at 7:50am), those rights disappear. The software then stops working. I can verify that the user rights are gone by using secedit /export /cfg e:\temp\uraExp.inf /areas USER_RIGHTS and I have a script that does this every 30 seconds and logs the results with a timestamp, so I know when the rights disappear. What I see from the export is that in the "good" state, i.e. after I install the software and it's working correctly, the line for SeBatchLogonRight from the secedit export includes the user accounts created by the software. But every few hours (sometimes more), those user accounts are removed from that line. The same thing can be seen by using the GUI tool Local Security Policy > Security Settings > Local Policies > User Rights Assignment > Log on as a batch job: in the "good" state, that policy includes the needed user accounts, and in the bad state, the policy does not. Based on the above-mentioned logging script and the timestamps at which the user rights are being removed, I can see clearly that some GPOs are causing the change. The GPO Operational log shows GPOs being processed at exactly the right times. E.g.: Starting Registry Extension Processing. List of applicable GPOs: (Changes were detected.) Local Group Policy I have run GPOs on demand using gpupdate /force, and was able to verify that this caused the User Rights to be removed. We have looked over local group policies till our eyes are crossed, trying to figure out which one might be stripping these User Rights to "log on as a batch job." We have not configured any local group policies on this machine, that we know of; so is there a default local group policy that might typically do such a thing? Are there typical domain policies that would do this? I have been working with our IT staff colleagues to troubleshoot the problem, but none of them are really GPO experts... They wear many hats, and they do what they need to do in order to keep most things running. Any suggestions would be greatly appreciated!

• I have been told to accept one error with Memtest86+

  - by DustByte

  Bought a new computer back in August with 4x4 GB RAM. Had problems with the RAM. They sent me four new sticks, which also generated errors. Singled out four sticks (from the eight I now had) that didn't generate any errors. Discovered by coincident a new RAM error last week (this time no BSOD). Contacted the company. According to them there have been issues with a bad stock from last summer so I got two tested 8 GB sticks sent to me. Been running Memtest86+ over the weekend. After 20 hours I got an error (see attached photo). The test has now been running for 37 hours but so far only this one error. I contacted the company where I bought the computer. They wrote back: I wouldn't worry about hat one fail. We have had similar situations here whereby it passes numerous times but then fails once. We think it's an issue with memtest, after all memory is faulty or it isn't so you can't really have it pass a few times, fail the next time around and then pass again! Please trust me on this and continue with the memory we sent you and if your problems continue we'll look at getting it replaced again. I gather from other forum posts that many people do not accept a single error. What could this single error signify, faulty RAM or a glitch in the MEMTEST program (or other)? Update: From the helpful comments below I conclude that an occasional (and rare) "random" error could occur and be acceptable, but repeated errors at the same address would indicate malfunction. Memtest has now run for 45 hours and I still have only one error. For everyone's information, I will keep running the test. In less than two days I am going away for a month. I will most likely leave Memtest running. As I do not have a UPS there is a risk that a power outage will ruin the experiment. The computer is a desktop so I cannot bring it with me (which would curiously have exposed it to more cosmic rays as I will be flying ;)).

• How to Remove Extensions From, and Force the Trailing Slash at the End of URLs?

  - by Kronbernkzion

  Example of current file structure: example.com/foo.php example.com/bar.html example.com/directory/ example.com/directory/foo.php example.com/directory/bar.html example.com/cgi-bin/directory/foo.cgi I want to remove HTML, PHP and CGI extensions from, and then force the trailing slash at the end of URLs. So, it could look like this: example.com/foo/ example.com/bar/ example.com/directory/ example.com/directory/foo/ example.com/directory/bar/ example.com/cgi-bin/directory/foo/ I've searched for solution for 17 hours straight and visited more than a few hundred pages on various blogs and forums. I'm not joking. So I think I've done my research. Here is the code that sits in my .htaccess file right now: RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.html -f RewriteRule ^(([^/]+/)*[^./]+)/$ $1.html RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]|/)$ RewriteRule (.*)$ /$1/ [R=301,L] As you can see, this code only removes .html (and I'm not very happy with it because I think it could be done a lot simpler). I can remove the extension from PHP files when I rename them to .html through .htaccess, but that's not what I want. I want to remove it straight. This is the first thing I don't know how to do. The second thing is actually very annoying. My .htaccess file with code above, adds .html/ to every string entered after example.com/directory/foo/. So if I enter example.com/directory/foo/bar (obviously /bar doesn't exist since foo is a file), instead of just displaying message that page is not found, it converts it to example.com/directory/foo/bar.html/, then searches for a file for a few seconds and then displays the not found message. This, of course, is bad behavior. So, once again, I need the code in .htaccess to do the following things: Remove .html extension Remove .php extension Remove .cgi extension Force the trailing slash at the end of URLs Requests should behave correctly (no adding trailing slashes or extensions to strings if file or directory doesn't exist on server) Code should be as simple as possible I would very much appreciate any help. And to first person that gives me the solution, I'll send two $50 iTunes Store gift cards for US store. If this offend anyone, I am truly sorry and I apologize. Thanks in advance. And sorry for such a long post.

• What the best way to achieve RPO of zero and lowest possible RTO (less than 15 minutes) with SQL 2008 R2?

  - by Adrian Hope-Bailie

  We are running a payments (EFT transaction processing) application which is processing high volumes of transactions 24/7 and are currently investigating a better way of doing DB replication to our disaster recovery site. Our current and previous strategies have included using both DoubleTake and Redgate to replicate data to a warm stand-by. DoubleTake is the supported solution from the payments software vendor however their (DoubleTake's) support in South Africa is very poor. We had a few issues and simply couldn't ever resolve them so we had to give up on DoubleTake. We have been using Redgate to manually read the data from the primary site (via queries) and write to the DR site but this is: A bad solution Getting the software vendor hot and bothered whenever we have support issues as it has a tendency to interfere with the payment application which is very DB intensive. We recently upgraded the whole system to run on SQL 2008 R2 Enterprise which means we should probably be looking at using some of the built-in replication features. The server has 2 fairly large databases with a mixture of tables containing highly volatile transactional data and pretty static configuration data. Replication would be done over a WAN link to a separate physical site and needs to achieve the following objectives. RPO: Zero loss - This is transactional data with financial impact so we can't lose anything. RTO: Tending to zero - The business depends on our ability to process transactions every minute we are down we are losing money I have looked at a few of the other questions/answers but none meet our case exactly: SQL Server 2008 failover strategy - Log shipping or replication? How to achieve the following RTO & RPO with logshipping only using SQL Server? What is the best of two approaches to achieve DB Replication? My current thinking is that we should use mirroring but I am concerned that for RPO:0 we will need to do delayed commits and this could impact the performance of the primary DB which is not an option. Our current DR process is to: Stop incoming traffic to the primary site and allow all in-flight transaction to complete. Allow the replication to DR to complete. Change network routing to route to DR site. Start all applications and services on the secondary site (Ideally we can change this to a warmer stand-by whereby the applications are already running but not processing any transactions). In other words the DR database needs to, as quickly as possible, catch up with primary and be ready for processing as the new primary. We would then need to be able to reverse this when we are ready to switch back. Is there a better option than mirroring (should we be doing log-shipping too) and can anyone suggest other considerations that we should keep in mind?

• Unknown problem causing major computer failure, Booting problem with windows 7, mainly with 0x0000000A

  - by ken

  Where do I begin? OS=Windows 7 I think it all started when I ran an installation file. I suspect it may have been a virus (even though AVG scan didnt pick anything up). The installation failed, computer crashed then restarted. In the middle of the reboot, I get BSOD. Normal boot up doesnt work so I use safe mode. Method 1: Not a problem I thought cos I will do what I normally do and that was to recover from my image file. Unfortunately, my Acronis software cant recover in safe mode. Method 2: I created a bootable disc for the Acronis recovery software. Managed to boot to Acronis and started the recovery from image file. This fail with some error message (did not manage to record). Something to do with not be able to copy to $AVG folder. Method 3: At this stage, assumed it was still a virus causing the problem so decided to format that partition to remove everything and hopefully the virus too. Had a lot of problems trying to bypass the system to allow me to format but (i think- more on this later) I managed to do that. Image was recovered, thought problem was resolved. Tried to boot windows but new error: Boot Manager is missing. Read up on this and managed to copy the Boot Manager from my Laptop's Manufacturer's partition (partition contains factory setup image file). Windows loaded but new BSOD with 0x000000A problem. Method 4: Attempted to reinstall factory settings but this failed cos i suspect by formating the partition, I may have removed the recovery software. Tried to create a bootable dvd of factory setting but machine is so bad it continues to crash. Bootable dvd method failed. Method 5:Spent alot of time reading up on this error, even installed a software to help scan and fix the problem. Scan failed and software required money! Anyway, lots of BSOD with different error message like 0x00000001A and 0x0000000D1. Error message changes with some reboots. Method 6: Found a hotfix from the windows site to fix 0x0000000A problem, great I thought! In safe mode, I cant install the file cos of error:0x8007043c. Tried to then install the fix in normal mode but installation just hangs. Returned to safe mode and followed advice to bypass 0x8007043c by changing the BITS status (read here: http://www.vistaheads.com/forums/microsoft-public-windowsupdate/181931-error-number-0x8007043c-windows-update.html). However, my machine at this time is so flaky that it hangs everytime i right mouse click the computer icon. I am at my wits end. Ya help or ideas? Cheers

• Nginx - basic http authentication on PHP-script

  - by half_bit

  I added a PHP-Script that serves as "cgi-bin", Configuration: location ~^/cgi-bin/.*\.(cgi|pl|py|rb) { gzip off; fastcgi_pass 127.0.0.1:9000; fastcgi_index cgi-bin.php; fastcgi_param SCRIPT_FILENAME /etc/nginx/cgi-bin.php; fastcgi_param SCRIPT_NAME /cgi-bin/cgi-bin.php; fastcgi_param X_SCRIPT_FILENAME /usr/lib/$fastcgi_script_name; fastcgi_param X_SCRIPT_NAME $fastcgi_script_name; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param GATEWAY_INTERFACE CGI/1.1; fastcgi_param SERVER_SOFTWARE nginx; fastcgi_param REQUEST_URI $request_uri; fastcgi_param DOCUMENT_URI $document_uri; fastcgi_param DOCUMENT_ROOT $document_root; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; fastcgi_param REMOTE_USER $remote_user; } PHP-Script: <?php $descriptorspec = array( 0 => array("pipe", "r"), // stdin is a pipe that the child will read from 1 => array("pipe", "w"), // stdout is a pipe that the child will write to 2 => array("pipe", "w") // stderr is a file to write to ); $newenv = $_SERVER; $newenv["SCRIPT_FILENAME"] = $_SERVER["X_SCRIPT_FILENAME"]; $newenv["SCRIPT_NAME"] = $_SERVER["X_SCRIPT_NAME"]; if (is_executable($_SERVER["X_SCRIPT_FILENAME"])) { $process = proc_open($_SERVER["X_SCRIPT_FILENAME"], $descriptorspec, $pipes, NULL, $newenv); if (is_resource($process)) { fclose($pipes[0]); $head = fgets($pipes[1]); while (strcmp($head, "\n")) { header($head); $head = fgets($pipes[1]); } fpassthru($pipes[1]); fclose($pipes[1]); fclose($pipes[2]); $return_value = proc_close($process); } else { header("Status: 500 Internal Server Error"); echo("Internal Server Error"); } } else { header("Status: 404 Page Not Found"); echo("Page Not Found"); } ?> The problem with it thought is that I cannot add basic authentication. As soon as I enable it for location ~/cgi-bin it gives me a 404 error when I try to look it up. How can I solve this? I thought about restricting access to only my second server where I then add basic authentication over a proxy, but there must be a simpler solution. Sorry for the bad title, I couldn't think of a better one.
