  • Setting up Virtual Host in Fedora Core 15 using apache

    - by Roland
    I'm trying to setup a couple of Virtual Host files on my Localhost PC running Fedora Core 15. Now I get this working, but now onloy one Virtual Host site works, and if I type in 127.0.0.1/test/testApp.php which is not related to the Virtual Host site , I get redirected to the Virtual Host site. Here's what I did. I created a new folder called virtualhosts in /etc/httpd/ where all my host files are stored in the following format site.conf In /etc/conf/httpd.conf I enabled NameVirtualHost *:80 and included the host files at the bottom of the config page like this Include virtualhosts/*.conf In /etc/hosts I added the line 127.0.0.1 website No when I run sudo httpd -t I get Syntax OK I restart apache and then the Virtualhost works, but as soon as I add other hosts and only use 127.0.0.1 as above it still links to the original host. Am I doing anything wrong here or left out something? An example of my Virtual Host file looks like this <VirtualHost *:80> ServerAdmin [email protected] DocumentRoot /var/www/html/website/ ServerName website ServerAlias website ErrorLog logs/dev-error_log CustomLog logs/dev-access_log common Alias /blog /var/www/html/blog/ <Directory /var/www/html/website/> Options FollowSymLinks Allow Override All Order allow,deny allow from all </Directory> #php_value error_reporting E_ALL & ~E_NOTICE & ~E_DEPRECATED php_flag display_errors On php_value date.timezone Europe/London </VirtualHost>

  • Korean characters not appearing in Korean Windows XP computer

    - by user13267
    I am using a Korean software (with a partial English interface) in a Korean Version of Windows XP SP 3 However, in parts of the software, even when I change the interface to Korean, Korean letters show up as random characters, as shown here: This is happening at others parts of the software as well, and I am not sure what is the difference between the places where this is happening, and places where this is not happening. For example, a command button where Korean letters are showing up properly is shown below: This software is a video conferencing software and has a chat feature as well. When I type into the chat box, i can see the Korean letters appear properly at my side, but when I press Enter and send the message, it changes into random characters as shown above in the chat box. What could be the issue here? Could it be a missing font in my computer? Since this is a Korean Windows installation I was hoping everything would work properly by default. What can be done here? EDIT 1: I asked some other people who are using this software, and they think that the problem is at my end, and playing around with the Regional and Language Settings might solve the problem. Also, they suggested I install all the language packs related to Korean display. But it looks like all the language packs have been installed, and my location is set to Korea in Regional and Language Settings in Control Panel, and I still have this problem. Also, I have had similar problems with displaying Korean on an English Windows XP computer. This answer suggested some solutions, but I still do not quite understand exactly what I have to do (at that time I had not fixed the problem, as I later on changed the computer). If I follow that answer, what fonts exactly do I need to install?

  • Sql Server 2005 Connection Unstable When Sharing Connection

    - by intermension
    When connecting to a customers hosting service via Sql Server Management Studio on an internet connection that also has other activity on it, the Sql Server connection to the hosting service is often dropped. An obvious work around to this problem is to NOT have additional traffic on the connection but it still begs the question "Why the Sql Server connection is so unstable?". If there is, for arguments sake, 100kb of bandwidth and a couple of downloads running that are being serviced at 35kB each then there is 30kB bandwidth spare capacity. If a 3rd download is started, that can be serviced at 35kB by the server, it will top out at 30kB and leave zero spare capacity. This is fine and all downloads get along nicely. However it seems that with Sql Server connections it doesn't matter if there is spare bandwidth. Sql Server regularly times out if there is any additional activity on the connection even if i have 1024kB spare bandwidth capacity. This has been experienced across different customer hosting providers over the years and so the assumption is that it's Sql Server related. Why does Sql Server (apparently) require exclusive access to the internet connection in order to maintain a connection... even if that connection has plenty of spare capacity over and above any additional activity on the connection?

  • How could I embed formatted XML source in WORD documents?

    - by eckes
    I'm writing a documentation with WORD that contains XML source code (whole files) as examples. The way I'm embedding the currently XML is quite cumbersome and doesn't seem to me as really maintainable: I'm finishing the editing of the document in WORD and create a PDF from it using Acrobat next, I open my XML files (2x input files, 2x generated output files) with IE and print them with the PDF printer supplied by Acrobat now, I open up Acrobat Pro and attach the four XML-PDF files to my original document The problem with that work flow for me is that it involves too much manual labor in order to get the documentation done. What I've tried up to now is not really satisfying for me: converting each XML to PDF and appending them like described above opening the XML files with SCiTE, copy as RTF and paste into Word playing around with the LaTeX packages minted, pygments and listings (I could write the docs with LaTeX too) but found some unsolvable problems in each of these packages I'm searching for a way that produces my documentation more automatic. For example embedding the XML files including formatting of IE (which I find quite readable). The files should be included by reference so that I don't have to paste the XML sources manually every time the XML changes.

  • What hardware would I need (approx) to run ESXi server?

    - by mr.b
    Hi, I am considering to purchase off-the-shelf commodity hardware in order to build server that will host virtual machines using ESXi server. Intended purpose for this server is NOT mission critical tasks. It will have to run perhaps 20-50 Windows XP/Vista/7 virtual machines (in total, but closer to 20 figure). Each guest would have to have 1-2 GB of ram, and probably two-three times more disk space than guest OS needs with clean install and all updates applied (that would be around 6-8 GB for XP, and i believe closer to 10-15 for win7). Those guests will act as a test ground for a new product that is network management software, thus guests will idle most of their time once initially loaded, but if I give them some task to complete, they should be able to perform reasonably well. Now, from what I have learned... CPU is usually not much of an issue (6 cores would do it), memory should not be lacking, but doesn't have to be sum of all guests, because of overcommitment... That leads me to IO, which is, as it seems, the bottleneck. Since I have very little experience with ESXi (and ESX, too) server, I'd like to ask: How much memory could I save by overcommitment, and how does it affect performance? Is 6-core cpu enough to run above described system? Would it be possible to run entire server off two (or even one) SSD drives (to host system virtual disks, with few additional HDDs (2-3) in RAID 0 to be used as secondary storage? I read somewhere that ESXi allows having something like "master image", essentially virtual machine that is "deployed" many times, so that disk space can be saved by having only differences stored by specific guests, instead of copying around whole virtual disks. Is this true, and how can this help me? Are there any other things I need to take into consideration when building this off-the-shelf solution? I should probably mention here that I'm fully aware of issues like SPOF regarding power supply, raid 0, etc, but since it's only a testing ground and not a production system, it's not so important for me. Thanks, B.

  • How can I fill (not replace) TAB with Spaces in MSWord?

    - by Morteza
    How can I fill (not replace) TAB with Spaces in MS Office Word? In other word, have a look at the following pic: 1 -> 222 -> 3 111 -> 2 -> 333 11 -> 22 -> 33 11 -> 2222 -> 3333 Suppose that - is indicated one TAB. As you see, each column is justified from left. I need to fill each TAB with Spaces, so that the justification not be confused. If I use 'Find & Replace' option to change each TABs to a specific number of Spaces, justification will be confused because each column have its own character number. In other word, if I change each TAB with 6 Spaces, the above will be changed to the follow: 1 222 3 111 2 333 11 22 33 11 2222 3333 My need is as follow (each dot indicate a Space): 1......222......3 111....2........333 11.....22.......33 11.....2222.....3333

  • How to boot XBMC 10.1 ISO on USB via grub?

    - by Shi
    I am trying to boot the XBMC Live image (http://xbmc.org/download/) as ISO from USB via grub 1.98. I have a Kubuntu 11.04 image there as well already and it works using the following configuration: menuentry "Kubuntu 11.04 64bit" { loopback loop /boot/iso/kubuntu-11.04-desktop-amd64.iso linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/boot/iso/kubuntu-11.04-desktop-amd64.iso noeject noprompt initrd (loop)/casper/initrd.gz } However, if I try to boot XBMC in an analogue way, I always get an error "Unable to find a medium containing a live file system". I found different approaches to install XBMC, but they all are about installing the distribution on USB, or using grub4dos, or unetbootin. I already found out that XBMC 10.1 is based on Ubuntu 10.04.2 LTS, so I tried those settings - even though they are quite similar to Kubuntu 11.04. Finally, the ISO contains a grub configuration as well in boot/grub/grub.cfg, but even with those parameters, I get the error above. My current configuration is the following one: menuentry "xbmc 10.1" { loopback loop /boot/iso/xbmc-10.1-live.iso linux (loop)/live/vmlinuz video=vesafb boot=live iso-scan/filename=/boot/iso/xbmc-10.1-live.iso xbmc=autostart,nodiskmount splash quiet loglevel=0 persistent quickreboot quickusbmodules notimezone noaccessibility noapparmor noaptcdrom noautologin noxautologin noconsolekeyboard nofastboot nognomepanel nohosts nokpersonalizer nolanguageselector nolocales nonetworking nopowermanagement noprogramcrashes nojockey nosudo noupdatenotifier nouser nopolkitconf noxautoconfig noxscreensaver nopreseed union=aufs initrd (loop)/live/initrd.img } Any more ideas or any more information I should supply?

  • Solutions on how to use an OS X calendar as a more perfect time tracking solution for 5-10 users in a small agency?

    - by jnthnclrk
    I really like OS X's iCal. Entering events is easy with the mouse and it also gives you a very real visual sense of how long tasks take to complete. We often work remotely in our organisation, so we use a few shared calendars between key individuals to provide us with an overview of hours worked, availability & schedule conflicts without too much disruption to our various, hectic workflows. It really is a neat solution, especially on shared tasks. How many times have you tasked a remote colleague and then lost the thread on whether that task was completed or not? With shared calendars you get a much clearer idea of what your people are working on without having to pick up the phone or compose a chat. However, there are a few areas where this approach fails... iCloud syncing often needs to be re-jiggered The "view only" option on shared calendars does not seem to work, which makes all shared calendars editable by others There is no decent reporting with this workflow There is no task categorisation or tagging Things get very busy in iCal when working with more than 2 shared calendars I've looked at a few task management apps like Basecamp and Harvest, but nothing appears to let me edit my calendar natively and then sync with a 3rd party. Interested in solutions to improve the above workflow and enable us to elegantly increase the amount of users.

  • How to troubleshoot Linksys E4200 Remote Management

    - by Jordan
    My Linksys E4200 is configured for Remote Management, but the router is not accepting the connections. Here's the configuration under Administration Management Remote Management Access: Remote Management: Enabled Access via: HTTP Remote Upgrade: Disabled Allowed Remote IP Address: Any IP Address Remote Management Port: 8080 The router is setup to use 192.168.10.41 as its static Internet IP address, and 192.168.35.1 as its LAN IP address. I can access the router just fine via its LAN IP address, but I can't make a connection using http://192.168.10.41:8080. I've tried variations of the settings above (enabled HTTPS, enabled Remote Upgrade, set an IP range of 192.168.10.1-254) but nothing has worked yet. Hoping someone can at least point me in the right direction. Thanks. Update: To clarify, I have a wired router that connects straight to the T1 modem. It's configured to use 192.168.10.1-254 as its internal LAN range. The E4200 wireless router in question is on that LAN using 192.168.10.41 as its WAN IP address. The E4200's internal LAN range is 192.168.35.1-254. I'm not trying to access the E4200 from the Internet, I'm just trying to access it from its WAN IP address. Thanks.

  • Linux Centos 6 becomes unavailable from time to time - OS&network issue

    - by adoado0
    I am encountering following problem. There is one server (DL160 G5) running Centos 6.3 with default kernel 2.6.32-220.2.1.el6.x86_64 - at this point I'd like to add that issue appeared also at older version - 6.1 and older kernel (do not remember exactly which version). There is cPanel installed and from time to time it becomes unavailable (network connection). What I've checked is (via KVMoIP): load average is completely normal it does not lack memory or disk space when problem occurs no console notifications checked all access logs and there is no sign that it can be caused by a client script cannot even access local interface (127.0.0.1) or main IP address running tcpdump I can only see packets arriving to server - no responses all services seem to be running properly (mail,sql,http,ssh) checked crontab and all clients' crontabs too network port utilisation is low ( up to several Mbits) arriving packet rate is low - hundreds per second (according to tcpdump) console (via kvmoip) works fine, no lags there is no conntrack at this server there is no ipv6 at this server flushing iptables, unloading modules does not resolve problem restarting network does not resolve problem, no errors appear it also occurs when two sepearate networks are configured (and multiple gateways) as well as one IP, one default gw and one network is configured - so it seems network configuration independent it seems to repeat randomly (load,packet rate,bandwith usage,load independent) checked server with different rootkit detection tools - it seems to be clean server has been rebooted, it did not change anything there are no interface errors it apperas randomly can be once a week or several times per day It usually works fine after 1-15 minutes. What I can also check? It is definitely OS issue - there is traffic at interface only in one direction when problem occurs, can not even ping loopback. Any ideas? Recommended checks? Anything I did not checked above.

  • Are email addresses mandatory for Windows 8 login names?

    - by Cedric Martin
    I've got a computer running Windows 8 and in the user accounts I can see four accounts (they're in french, here's a rough translation): [email protected] / administrator Veronique YYY / [email protected] ASP.NET Machine Account / local account guest account / the guest account is desactivated I've got several questions but they're all related to email addresses and login names / accounts. Are email addresses mandatory for Windows 8 login names? Can you mix live and non-live user accounts on a Windows 8 system? Is it possible to have a live Windows 8 user account which is not using a @live.xx email address? Is it possible to have a non-live Windows 8 user account which is using a @live.xx email address? If the gmail.com email address of the admin is not a live Windows 8 account, does this mean I can create a "fake" email and use that as the email of a new Windows 8 account? Basically I don't understand very well why there are email addresses displayed on the login screen and why there are both @live.xx and @gmail.com email addresses on the same system and answer to the questions I asked above may help me understand a bit better what is going on (I'm coming from a Linux / OS X background. I literally haven't used Windows in more than a decade).

  • Master File Table Corrupt, any way to save data?

    - by domen
    hi. I've used search, but none of the results match my problem so I didn't have to ask separate question. I've Installed Windows 7 RTM recently and since then partitions located on one of my HDDs have gone "crazy". They used to "freeze" and didn't open in explorer for some time (minute or two, usually), sometimes all partitions of the drive wouldn't show until reboot and finally, one of those partitions started showing "disk structure is corrupted and unreadable" warning, it appeared in Disk Management window as RAW and chkdsk showed "mft corrupt". There were no important data on the partition and I didn't have enough time to analyze the problem at the moment, so I just reformatted it and ran antivirus scan on system. After that problem settled for some time, but yesterday the problematic HDD vanished again from the system. After reboot chkdsk identified mft of four partitions corrupt and now they are all in same conditions as the above mentioned one. But the difference is that the files stored in them are extremely important. and just for info: I upgraded from Win7 build 7077, but had some performance issues, so I reformatted system drive and installed fresh Win7 RTM on it. I've downloaded TestDisk and it shows all the partitions marked as NTFS (not RAW) and my knowledge of the program wasn't sufficient to obtain any other info from it :-) and the images that could help describe the problem (sorry, I'm not allowed to post images and more than one hyperlink): http:// img22.imageshack.us/img22/5909/chkdskz.jpg http:// img198.imageshack.us/img198/5576/computeray.jpg I'm interested, is there a way to let me restore the MFT or just access files so I can backup them before reformatting the drive. Thanks for your time. :) P.S. my reformatted drive is showing no problems, could there be a problem with windows 7 itself? I googled, but with no results.

  • What can inexperienced admin expect after server setup completed seemingly fine? [closed]

    - by Miloshio
    Inexperienced person seems to have done everything fine so far. This is his very first time that he is the only one in charge for LAMP server. He has installed OS, network, Apache, PHP, MySQL, Proftpd, MTA & MDA software, configured VirtualHosts properly (facts because he calls himself admin), done user management and various configuration settings with respect to security recommendations and... everything is fine for now... For now. If you were directing horror movie for server admin above mentioned what would you make up for boogieman that showed up and started to pursue him? Omitting hardware disaster cases for which one cannot do anything 'from remote', what is the most common causes of server or part-of-server or server-related significant failure when managed by inexperienced admin? I have in mind something that is newbie admins very often missing which is leading to later intervention of someone with experience? May that be some uncontrolled CPU-eating leftover process, memory-related glitch, widely-used feature that messes up something unexpected on anything like that? Newbie admin for now only monitors disk-space and RAM usage, and number of running processes. He would appreciate any tips regarding what's probably going to happen to his server over time.

  • Script to mirror MS SQL Server databases between 2 servers

    - by David W
    Hi I have about 200 sites each of which have 2 servers running MSSQL (2k5 at some sites, 2k8 at others) One server is production and the other is primarily there as a backup. We're rebuilding all of these servers this year and as part of that we will have to set up mirroring for ... a lot ... of databases. Some of these sites have 45 databases so mirroring them manually is going to be a huge pain. I was going to write a batch script which uses SQLCMD to backup the database and log, copies to the secondary server, restores the backup and log with norecovery, creates the endpoints and sets the partner. This in itself isn't too complicated, but i'd love to see what other people have done as i'm not very confident in catching errors using the process i've outlined above. I've seen Tools to manage sql 2008 database mirroring? Which looks really good, but the formatting is jumbled and I can't get it to work. If anyone has any other scripts they've written and are willing to share I'd be eternally grateful. Ideally I'd love to be able to use a script to ensure there are matching endpoints (same ports) on both servers, backup the database, backup the log, copy the backups to second server, restore database and log with norecovery, set the partners on both servers, and somehow confirm that the databases are linked and synchronized. Well, thanks for reading :)

  • Deploying multiple identical copies of a virtual machine for compute tasks

    - by Reid
    I have a compute task which has a large number of library dependencies. I would like to deploy it on some of my company's large Linux clusters, where I do not have root. I could probably track down, compile, and install the right versions of all the libraries, but this looks to be quite tedious and would have to be repeated if I deployed it again somewhere else. On the other hand, it's pretty easy to install on current Ubuntu. This led me to wonder about a virtual machine approach. Could I put together a virtual machine which booted up, ran the computation (with parameters from and results to the host), and then shut down? In other words, I'd like a command like this that I could run on the host: $ ./run-vm --ram N --task /path/on/host/foo.sh --results /another/host/dir/ This would boot the VM, run foo.sh, and put the (relatively small) results of the computation in /another/host/dir/. It's important to start up many instances of the VM simultaneously, both on a single node and multiple nodes of the cluster. So it would be nice if I didn't have to make many copies of the VM virtual disk and metadata. As the task instances are completely independent, the VMs would not need any network support once deployed, or any outside communications beyond reading and writing the host filesystem. Is this possible, and if so, how might I go about doing it? Are there assumptions I've made above which are bogus?

  • Fill down in Excel, but based on multiple values

    - by Jenn D.
    I have spreadsheets (not created by me) that have blank entries in one column where they should really have data. I want to take every empty cell and fill it with the nearest value above it. I'm looking for as little manual intervention as possible, because I'll have to do it repeatedly. I thought some previous version of Excel, or maybe another spreadsheet from the distant past, would do this by default -- that is, if you selected the column with foo and bar, and chose the equivalent of "fill down", you would get what's in the WANT column. What I actually get in Excel is the GET column. HAVE: WANT: GET: foo 1 foo 1 foo 1 2 foo 2 foo 2 bar 1 bar 1 foo 1 2 bar 2 foo 2 3 bar 3 foo 3 I'm worried that this might need a macro to be done properly. I used to be a whiz with Excel macros, and then suddenly they were all in VB. My fallback position will be to dump the whole thing to CSV and write a Python script, but if there's any way to do it in Excel that would be much preferable. Even if it involves a couple of different manual steps, that's fine; just not one step per group of lines. That is, a process of "copy the column, do X to it, cut and paste it back" would work, but "do X for each occurrence of foo or bar" won't. The files are too big for that. Any thoughts are appreciated!

  • Diagnosing Random Network Lag

    - by uesp
    I'm having trouble diagnosing some random lag on a 6 server LAMP cluster serving a MediaWiki site. While we're serving some 100 pages/sec the servers themselves are running fine with less than 0.5 load, no locked processes, no paging, no errors being logged, etc.... Lag is present on all servers and is random: one minute its fine the next it's there. DNS lookups on the servers are randomly slow. For example time nslookup google.com varies randomly from a few milliseconds to several seconds and sometimes times out entirely. While we use IP addresses internally on the cluster this may be a symptom of the root issue. We are not running our own DNS server. The Apache server-status pages randomly lag or time out. Benchmarking using ab between servers shows a few loads sometimes take 3000 ms (almost exactly). Benchmarking server-status on the local server itself usually shows no issue (it showed a lag only once among a few hundred tests). The servers are sitting behind a switch and a firewall which I don't have any access to so I don't know their setup or status. While we are under heavier than normal load a 2 Mbps incoming and 20 Mbps outgoing traffic shouldn't be stressing the switch or firewall should it? My feeling is that it is the switch/firewall or something above them in the ISP like their DNS but can't confirm it. I need some other tests or methods of diagnosing this lag to try and narrow down the ultimate cause.

  • What is the risk of introducing non standard image machines to a corporate environment

    - by Troy Hunt
    I’m after some feedback from those in the managed desktop or network security space on the risks of introducing machines that are not built on a standard desktop image into a large corporate environment. This particular context relates to the standard corporate image (32 bit Win XP) in a large multi-national not being suitable for a particular segment of users. In short, I’m looking at what hurdles we might come across by proposing the introduction of machines which are built and maintained by a handful of software developers and not based on the corporate desktop image (proposing 64 bit Win 7). I suspect the barriers are primarily around virus definition updates, the rollout of service packs and patches and the compatibility of existing applications with the newer OS. In terms of viruses and software updates, if machines were using common virus protection software with automated updates and using Windows Update for service packs and patches, is there still a viable risk to the corporate environment? For that matter, are large corporate environments normally vulnerable to the introduction of a machine not based on a standard image? I’m trying to get my head around how real the risk of infection and other adverse events are from machines being plugged into the network. There are multiple scenarios outside of just the example above where this might happen (i.e. a vendor plugging in a machine for internet access during a presentation). Would a large corporate network normally be sufficiently hardened against such innocuous activity? I appreciate the theory as to why policies such as standard desktop images exist, I’m just interested in the actual, practical risk and how much a network should be protected by means other than what is managed on individual PCs.

  • Skipping nginx PHP cache for certain areas of a site?

    - by DisgruntledGoat
    I have just set up a new server with nginx (which I am new to) and PHP. On my site there are essentially 3 different types of files: static content like CSS, JS, and some images (most images are on an external CDN) main PHP/MySQL database-driven website which essentially acts like a static site dynamic PHP/MySQL forum It is my understanding from this question and this page that the static files need no special treatment and will be served as fast as possible. I followed the answer from the above question to set up caching for PHP files and now I have a config like this: location ~ \.php$ { try_files $uri =404; fastcgi_cache one; fastcgi_cache_key $scheme$host$request_uri; fastcgi_cache_valid 200 302 304 30m; fastcgi_cache_valid 301 1h; include /etc/nginx/fastcgi_params; fastcgi_pass unix:/var/run/php-fastcgi/php-fastcgi.socket; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /srv/www/example$fastcgi_script_name; fastcgi_param HTTPS off; } However, now I want to prevent caching on the forum (either for everyone or only for logged-in users - haven't checked if the latter is feasible with the forum software). I've heard that "if is evil" inside location blocks, so I am unsure how to proceed. With the if inside the location block I would probably add this in the middle: if ($request_uri ~* "^/forum/") { fastcgi_cache_bypass 1; } # or possible this, if I'm able to cache pages for anonymous visitors if ($request_uri ~* "^/forum/" && $http_cookie ~* "loggedincookie") { fastcgi_cache_bypass 1; } Will that work fine, or is there a better way to achieve this?

  • Is it possible to use rsync over sftp (without an ssh shell) ?

    - by Tom Feiner
    Rsync over ssh, works great every time. However, trying to rsync to a host which allows only sftp logins, but not ssh logins, provides the following error: rsync -av /source ssh user@remotehost:/target/ protocol version mismatch -- is your shell clean? (see the rsync man page for an explanation) rsync error: protocol incompatibility (code 2) at compat.c(171) [sender=3.0.6] Here's the relevant section from the rsync man page: This message is usually caused by your startup scripts or remote shell facility producing unwanted garbage on the stream that rsync is using for its transport. The way to diagnose this problem is to run your remote shell like this: ssh remotehost /bin/true > out.dat then look at out.dat. If everything is working correctly then out.dat should be a zero length file. If you are getting the above error from rsync then you will probably find that out.dat contains some text or data. Look at the contents and try to work out what is producing it. The most com- mon cause is incorrectly configured shell startup scripts (such as .cshrc or .profile) that contain output statements for non-interactive logins. Trying this on my system produced the following in out.dat: ssh-dummy-shell: Command not allowed. As I thought, the host is not allowing ssh logins. The following link shows that it is possible to accomplish this task using fuse with sshfs - however it is extremely slow, and not fit for production use. Is there any chance of getting rsync sftp to work?

  • Howto get exit code of a script started in screen session

    - by Bettina
    Hi folks, I am currently creating a backup script which uses screen to start a backup job with rsync inside a screen session. The backup jobs are started as follows. screen -dmS backup /usr/bin/rsync ... As soon as the rsync job is finished, the screen session is terminated automatically. To make sure, that the backup was successful, I would like to check the exit code of the rsync job but unfortunately I really don't know how to get the exit code after the screen was terminated. Does someone have a good idea how to automatically check, if the rsync job was successful or not? Would be great if someone does. I already thought about using a temp file but like this: screen -dmS myScreen "rsync -av ... ; echo $? /tmp/myExitCode" but this unfortunately does not work. Then I thought about using stderr like in the example below: screen -dmS myScreen "rsync -av ... 2 /tmp/rsync-sterr None of my ideas worked out so far, since stderr is not written when I use the command above. :-( ? Would be great if someone has a good idea or even a solution. Cheers, Bettina

  • PHP-FPM processes holding onto MongoDB connection states

    - by Brendan
    For the relevant part of our server stack, we're running: NGINX 1.2.3 PHP-FPM 5.3.10 with PECL mongo 1.2.12 MongoDB 2.0.7 CentOS 6.2 We're getting some strange, but predictable behavior when the MongoDB server goes away (crashes, gets killed, etc). Even with a try/catch block around the connection code, i.e: try { $mdb = new Mongo('mongodb://localhost:27017'); } catch (MongoConnectionException $e) { die( $e->getMessage() ); } $db = $mdb->selectDB('collection_name'); Depending on which PHP-FPM workers have connected to mongo already, the connection state is cached, causing further exceptions to go unhandled, because the $mdb connection handler can't be used. The troubling thing is that the try does not consistently fail for a considerable amount of time, up to 15 minutes later, when -- I assume -- the php-fpm processes die/respawn. Essentially, the behavior is that when you hit a worker that hasn't connected to mongo yet, you get the die message above, and when you connect to a worker that has, you get an unhandled exception from $mdb->selectDB('collection_name'); because catch does not run. When PHP is a single process, i.e. via Apache with mod_php, this behavior does not occur. Just for posterity, going back to Apache/mod_php is not an option for us at this time. Is there a way to fix this behavior? I don't want the connection state to be inconsistent between different php-fpm processes.

Just over write? Options to merge (format etc for 7zip) ? Or I must use I tried to keep the 3 files with the other unetbootin files but get an error msg Files I have on my USB 06/30/2013 11:44 PM 2,835,648 ubnkern 06/05/2013 12:14 AM 3,998,007,296 debian-7.0.0-amd64-DVD-1.iso 06/04/2013 03:30 PM 4,696,872,960 debian-7.0.0-amd64-DVD-2.iso 06/05/2013 01:25 AM 4,698,955,776 debian-7.0.0-amd64-DVD-3.iso 06/30/2013 11:45 PM 6,530,278 ubninit 06/30/2013 11:46 PM 155 syslinux.cfg 06/30/2013 11:46 PM 60,928 menu.c32 also i can only copy above files if i format my USB as NTFS On FAT32 says too large to copy .iso How do I get around that? My internet needs a login so cannot do net install

  • Can't ssh from CentOS 6.5 to SUSE LINUX 10.1

    - by Pavel Tankov
    We have a quite old installation of SUSE LINUX 10.1 (i586) in the office. The problem shortly: I can successfully ssh to it from machines in the same LAN (192.168.1.0) and not from others (that are in 10.23.0.0). The SuSE has SSH server openssh-4.2p1-18.12. I have ruled out the firewall and hosts.allow and hosts.deny files. When my ssh login attempt fails, here is what the logs say: on the client: $ ssh -vvv 192.168.1.5 OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug2: ssh_connect: needpriv 0 debug1: Connecting to 192.168.1.5 [192.168.1.5] port 22. debug1: Connection established. debug1: identity file /home/nbuild/.ssh/identity type -1 debug1: identity file /home/nbuild/.ssh/identity-cert type -1 debug1: identity file /home/nbuild/.ssh/id_rsa type -1 debug1: identity file /home/nbuild/.ssh/id_rsa-cert type -1 debug1: identity file /home/nbuild/.ssh/id_dsa type -1 debug1: identity file /home/nbuild/.ssh/id_dsa-cert type -1 on the server: Aug 21 16:34:25 serverhost sshd[20736]: debug3: fd 4 is not O_NONBLOCK Aug 21 16:34:25 serverhost sshd[20736]: debug1: Forked child 20739.

I feel I've tried everything already.
