  • Handling expected supervisord exit codes

    - by Mulkave
    I am using supervisord inside a Docker container to manage my running processes and would like to also use it to trigger certain commands - run them once and expect them to exit with 0. Here's one example: [program:central-seed-posts] command = /usr/bin/php /var/www/app/artisan post autostart = false autorestart = false startsecs = 3 startretries = 0 exitcodes = 0 stderr_logfile=/tmp/central/posts-stderr-supervisor.log stdout_logfile=/tmp/central/posts-stdout-supervisor.log And I'm using nsenter's docker-enter with supervisorctl start central-seed-posts to trigger it but I would also like to handle a successful exit instead of supervisor telling me ERROR (abnormal termination) Does it have to do with supervisor events ?

  • ErrorDocument 404 not found in non-existent subdomain

    - by Question Overflow
    I am trying to get the apache server to issue a custom 404 error for invalid subdomains. The following is the relevant part of the httpd configuration: Alias /err/ "/var/www/error/" ErrorDocument 404 /err/HTTP_NOT_FOUND.html.var <VirtualHost *:80> # the default virtual host ServerName site_not_found Redirect 404 / </VirtualHost> <VirtualHost *:80> ServerName example.com ServerAlias ??.example.com </VirtualHost> What I get instead is this: Not Found The requested URL / was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. I don't understand why a URL to non-existent-subdomain.example.com produces a 404 error without custom error as shown above while a URL to eg.example.com/non-existent-file produces the full custom 404 error. Can someone advise on this. Thanks.

  • Setting Up Customer-Specific Domains

    - by GregT
    I can go to Fog Creek's web site, setup a new account, and they will instantly assign me a URL such as 'mycompany.fogbugz.com' (where 'mycompany' is something I make up, as opposed to some value assigned by Fog Creek). I can do the same type of thing with Beanstalk and many other vendors. I have been Googling around trying to figure out exactly how this works. 1: In the above example, is 'mycompany.fogbugz.com' set up in DNS in some special way other than how one would setup a vanilla 'www.foo.com' domain? 2: Assuming Fog Creek uses Tomcat (which I am sure is NOT true, but pretend it is) would they be likely to have created a tomcat/webapps/mycompany subdirectory on their server? Or is there some simpler way to handle this? I'm obviously not a DNS or TC wizard. Any insight appreciated. Happy New Year!

  • why is 64 bits version called AMD64 and 32 bits version called i386?

    - by ajsie
    I have never understood this. This is what i know: 64 bits OS if you want to handle more than 2GB RAM. Else, 32 bits OS. So on Ubuntu's homepage you can download either 64 bits or 32 bits. But the 64 bits is called amd64 and the 32 bits is called i386. So i have to have a AMD processor to run amd64? And intel to run i386? And if someone codes a software (lets say Apache). Does he have to code one 32 bits and one 64 bits? Do some softwares only exist for 32 and not 64 and vice versa? Thanks in advance!

  • Forward Request to Multiple Servers

    - by cactuarz
    We have 2 servers. One is old server and another is the new one. Currently we about doing a migration because the old server is not capable enough to handle everyday requests. The specs are: Old server Ubuntu 10.04 Nginx as Reverse Proxy Apache WSGI Python/Django New Server Ubuntu 10.04 Nginx Gunicorn Python/Django Celery+Redis Our manager asked us to research if the old server can perform multiple forwarding to all incoming request, for example, set Nginx of old server to forward all request to both old and new server. The purpose is to perform unit testing to new server using old server as comparer, see if the new server is ready to take over the role. Please help, if there is an idea, or must install some engine, or what we do is impossible. Many thanks.

  • 5 x 3GB drives and 4 x 1500GB drive best raid setup?

    - by Zen_Silence
    Hello, I am building a file server my plan is the have the Operating system on one raid partition and the data storage on another partition. I currently have 5 x 3GB IDE drives that i would like to put the operating system on theses drives are old but that doesnt matter to me at the moment i have a ton of them so for this raid partition i would probably want to be able to pull out dead a drive and rebuild the array. My file partition is going to consist of 4 x 1.5TB SATA drives I would like the maximum storage with some redundancy. Any suggestions to which Raid level i should use would be greatly appreciated and if you could also suggest a PCI or PCI-e raid controller to handle theses arrays. Thanks in Advance, Zen_Silence

  • snmptrap and snmptt - authcommunity not found

    - by sabs6488
    I am trying to configure snmptt to translate the snmp traps received and handle them as passive checks in icinga monitoring server as described here . after doing the changes to the snmptrapd.conf . I am trying to restart the service and I see authcommunity : command not found, traphandle : command not found . my understanding is the authcommunity and traphandle are just configuration directives which will tell snmptrapd about the community string to use and the traphandle script to be called. It would be helpful if someone can help me understand better. Thanks, sabs

  • Force snmptrapd to log only v2c traps

    - by dare2be
    Hello, I am in the middle of writing new network management software for my University. However, I need to implement a quickie solution to handle specific traps. Right now, my snmptrapd is configured to accept any traps, i.e.: # /etc/snmp/snmptrapd.conf authCommunity log publicString logOption f /var/log/snmptrapd.log format1 "" format2 "%02.2h:%02.2j %b %N\n" What I basically want to do is to log ONLY v2c traps. I intended to do it with setting the format for v1 traps to null (format 1 "") but snmptrapd keeps sending "" to its log. Does anybody know a workaround for this?

  • Help looking before I leap! I need expert guidance...

    - by Ellen Reddick
    27" iMac running win7 under bootcamp (slick! ). I have Access 2003 program with files linked through ODBC used by 4 installations (all with Access 2003 installed). I want to buy Access 2010 and try it under virtual PC (under Bootcamp). Will it work (since I have to install the ODBC drivers)? If I decide after this trial that I like what it does, can I then install it under the Windows 7 bootcamp partition (with or without uninstalling the virtual PC) without using up the 2nd allowed installation? Also, I see that MS allows an Office Pro 2010 trial download good for 60 days. Would this work in Windows 7 Virtual PC and would it be a better way to go, followed by a legitimate purchase of Access 2010 for the Windows 7? This is not an Access programming question--I realize there may be some tweaks necessary in the program to run it under 2010 and I can handle that part.

  • Sharepoint 2010 reacts very badly to having it's IP address changed. How do I fix it?

    - by Jeff Sacksteder
    I have Sharepoint 2010 set up on a virtual host for prototyping various projects. If I restart the host, the IP changes. Afterwards, SP complains that it can't find it's configuration database. I can't find where it might be storing an IP. To clarify, the URL remains the same - I have a dynamic dns solution in place to handle that. I can't see anything in the web.config files or the database connection strings that would indicate a hardcoded IP. How can I fix this up in less time than re-installing every time I need to do a project?

  • Amazon and bandwidth limits

    - by Dave
    This question may sound weird to some of you but I have never really used cloud and above all I'm still beginner in the web development and would be really thankful if someone could answer few of my question though they may sound weird So I would like to deploy simple website to Amazon, however, I'm concerned about bandwidth as they charge 0.12GB and I'm not able to set budget limit. My problem is that I wouldn't like to pay for 1000GB of bandwidth if someone for some reason decides to download one file constantly So could some of you, who have experience with amazon, tell what happens if my app is able to handle (say 50 req/sec 30kb/page) does that mean that in the worst case I would have to pay req * sec * min * hours * days * page size 50 * 60 * 60 * 24 * 30 * 30kb = 3888GB

  • Tracing what program is making a network connnection? (CentOS)

    - by Airjoe
    I was wondering if it is possible to find out which process is trying to make a specific network connection. On a server I support which hosts websites for about 200 users, the iptables firewall keeps blocking, as it should, a connection to 212.117.169.139 on port 80. Firefox reports this as an attack page (and at the least is obvious spam, if not malicious). It seems something on this server is trying to access this site for some reason, and although it's being blocked successfully, the requests seem to be going through every two to sixty seconds and I'd like to be able to find what process or script is doing this so I can handle it appropriately. Besides doing a grep to try and find if this IP is in some file (which probably won't even work because it may be working by hostname or it may be encoded), is there any way to find out some more information? Thanks!

  • Use a media player in Linux just to play files from an iPod device (no sync, no manage, just play)?

    - by Somebody still uses you MS-DOS
    I have an ipod classic 160gb, that I sync with my machine at home. I use Linux at work, and want to just plug my ipod and just listen to the tracks, with all the playlists and such. I don't want to sync nothing, I just want to listen to the tracks as if I was using the ipod itself. Why? Because this way I can use the usb port. So, I don't want to manage my ipod in Linux, I just want to listen to the tracks on it in Linux, like it was a local library but it's instead in my ipod. (I've tried gtkpod, it works to show my files, but I can't play, shuffle, etc. It would be interesting to have a complete audio software to handle everything like it was a local library)

  • Super simple high performance http server

    - by masylum
    I´m building a url shortener web application and I would like to know the best architecture to do it in order to provide a fast and reliable service. I would like to have two separate servicies in different machines. The first machine will have the application itself with a apache, nginx, whatever.. The second one will contain the database. The third one will be the one that will be responsible to handle the short url petitions. For the third machine I just need to accept one kind of http petition (GET www.domain.com/shorturl), but it have to do it really fast and it should be stable enough. Which server do you recommend me? Thank's in advance and sorry for my english

  • Specific cron at time point [closed]

    - by ARTI
    I have a very specific task, but can't handle it. I am not a programmer and totally n00b on bash scritps. So the question is, how to create a cron job like this: Script A.sh could be called at any time by hands, and it should create cron job to run script B.sh once at the nearest time point. For example I will have 4 time points: 10.00pm, 10.15pm, 10.30pm, 10.45pm. So if trigger a script A.sh at 10.07pm it should creat cron job to run ONCE script B.sh at 10.15h, because 10.15h is the nearest time point in future. Is it possible? How can I write such script A.sh? I use Centos 6 It is very important and urgent for me. Thank you very much.

  • Can I use Veritias Storage Manager to provide HA storage using server-local storage?

    - by Paul
    I have a need to provide an high-availability ftp/http file repository. Upload will happne to one server, but the uploaded file must be immediately visisble on all other servers I can handle the failover of the servers themeselves using load balancers. But in the event of failure of one server, the other servers must see the same contents of the repository. Normally, I'd use a SAN for this, but in this case the data centre standards do not allow SAN/external storage - all storage will be local to the servers. Cam I use Veritas Storage Manager (or any other product) to manage mirroring hte contents between servers in this way? Or does that require a SAN? I couldn't tell either way from a quick look at the data sheets etc.

  • Cannot delete movie on iTunes for iPhone 4?

    - by Jian Lin
    I was on vacation and took some videos, and now the iPhone 4 memory is near full. So I tried to delete other experimental movies I made using Handbrake, so that I can take more video or photos, but if I plug the iPhone 4 into my Notebook computer, I can seem to delete it on iTunes? Maybe because the computer I sync with the iPhone 4 is at home (a desktop), but not with me on vacation. I can't delete it on iTunes, can't delete it on iPhone itself. I am stuck during the vacation, or is there a way to handle it?

  • How are suspected DoS attacks handled by webservers?

    - by Jan Kuboschek
    I rent a server somewhere out in Canada or so that I'm using to host a website of mine. That website has close to 400,000 pages that I wanted to index today. For that, I wrote a crawler a while back (see JCrawler on Stackoverflow.com). Now, I'm greedy and didn't want it to take too long so I ran multiple threads resulting in some 60+ requests per second from my IP. A couple minutes later, my server locked me out. I can still FTP into it, but I can't HTTP it. As server administrator or user, do you have any idea how servers usually handle these situations? Is it common to place a permanent or temporary ban on the IP or what is typically done? Naturally, I'll re-run my software with fewer requests once I'm back on.

  • Failing SSHFS connection drags down the system

    - by skerit
    From time to time my sshfs mount fails. All programs using the mount freeze when it happens. I can't even ls anything or use nautilus. Is there a way to find out what's the cause and how to handle it? I've noticed regular SSH sessions to the server get their fair share of Write failed: broken pipe disconnects, too. If I wait long enough (and I'm talking about 20-ish minutes, here) it will auto reconnect and things start working again.

  • How to block null/blank user-agents in IIS 7.5

    - by Jeremy
    We are going through a large scale DDOS attack, but it isn't the typical bot-net that our Cisco Guard can handle, it is a BitTorrent attack. This is new to me, so I am unsure how to stop it. Here are the stats IIS is processing between 40 and 100 requests per second from BitTorrent clients. We have about 20% of the User Agents, but the other 75% are blank. We want to block the blank user agents at the server level. What is the best approach?

  • What is a good solution for an intranet video portal (YouTube-like) site?

    - by Ken Pespisa
    I would like an easy-to-setup site to handle videos to be viewed internally by my company. YouTube is essentially the perfect solution except for its being public. I'm looking for a place where a few people can upload videos, and the system will return a page where they can watch that video in a browser. I figure this would involve a dedicated Web server to run the Web application and process the videos. I've searched and I don't think such a system exists, but I perhaps there's one out there in its infancy that doesn't rank high on Google yet. Essentially the site I'm looking for is what MediaWiki is to Wikis, or what StackExchange is to Q&A sites, but for videos. Thanks in advance!

  • Possible to load entries into hosts.deny from text file?

    - by Tar
    I have around 96 million IP addresses that I have collected and routinely validate to be VPN providers, proxies, etc. I want these blocked. Currently, I am including the list formatted like deny ip; in nginx and that works perfectly. I want to use this list on another server, but nginx isn't an option, and I don't trust apache to handle this without slowing down. Is there a way to load this list into hosts deny via some command like aclexec or something? Are there other alternatives like setting up a DNSBL or using hosts.deny in conjunction with one?

  • Controlling TV Channel Through Computer

    - by killianmcc
    I'm passing my TV input through my computer so that I can use the video stream in an application I'm creating which then outputs to my TV. E.g. Sky Digibox/FreeView box - Laptop - TV Where on my laptop I'll be using the stream in a WPF application so I can overlay XAML objects onto it. My question is, what would be the best way for me to send the signal back to the box to say change the channel for example? I don't want to have to use the remote, I want the computer to handle everything. Is there a standard cable these boxes have that could take what would normally be a remote control signal and use that as input instead? Or would I have to go down the route of looking at some sort of Infared LED to send the signal recreating the remote? Apologies if this is not clear enough, let me know and I'll try and be more precise.

  • Ubuntu (desktop) server needed for school

    - by Dave Moody
    I need to build an ubuntu server for school, but I hate with a passion command line interfaces. I need a server with a desktop, like the current win server 2003 (which has crashed, ugh). This server needs to host the school lan domain, have an active directory, and handle the roaming profiles that the students and staff access through WinXP workstations. It also needs to work as a file server, maybe a print server. Can anyone advise me on how to create an Ubuntu server starting with Ubuntu Desktop edition? Much thanks if you respond... Dave.
