• Unable to access network resources through VPN

  - by fbueckert

  I'm currently attempting to connect one of our computers in the office to a client VPN. My development machine is running Windows 7, and can connect and see resources just fine. The problem computer is running Windows XP. They're both within the same network. Using the same credentials at both computers, the VPN connection (using the built in Windows network connections) works just fine. So far, so good. An IP address is assigned, and comparing both machines shows they're still in the same subnet. The problem is that the XP machine cannot see ANY of the computers in the client network. I tried a tracert to a target machine on the Windows 7 box, and the first item that comes up is the .0 address. Pinging it gives responses. Trying it on the Windows XP machine, however, comes up with just timeouts. Trying to trace to www.google.com allows the address to resolve (probably part of the cached resolutions), but results in just timeouts. I double-checked to make sure that the Windows firewall was not on, and trying to open the settings brings up a notification that the firewall service wasn't running, which leads me to believe that it's definitely not on. From my best guess, I've managed to connect the XP machine to a black hole of some sort. There's obviously something strange going on, but I'm not sure where I should be looking.

• How should I configure nginx caching headers for a "baked" static file blog? (Octopress)

  - by Doug Stephen

  I recently deployed an Octopress blog (which is a blogging platform built around Jekyll). It's a static-site blog generator, with no dynamic content or databases to muck about with. It's being served up by nginx. My question is, what is the appropriate expires directive or Cache-Control header that I should set to make sure that visitors get the most up-to-date version of the site when they visit without having to manually refresh? Since the site is just .html files it seems to get cached pretty aggressively. I've tried a million different combinations of expires modified + xxxx and even straight up expires off but I can't seem to wrap my head around it. I'm very new to dealing with caching like this, specifically, on static files that change frequently, and obviously if the site hasn't been changed then I'd like for it to be served up out of the cache. Update (still not solved though): I found open_file_cache, tweaked that. Still no dice. It seems like what I might want to do is use nginx as a proxy cache and use Apache with ETags? Is there really no convenient way to make nginx play nicer with conditional requests from the client? TL;DR: I'm running a static-file blog and I'd like to set up nginx to only serve from the cache if the blog hasn't been updated recently, but I'm too stupid to figure it out myself because I'm relatively new to web servers.

• User authentication -- username mismatch in IIS in ASP.NET application

  - by Cory Larson

  Last week, an employee's Active Directory username was changed (or a new one was created for them). For the purposes of this example, let's assume these usernames: Old: Domain\11111 New: Domain\22222 When this user now logs in using their new username, and attempts to browse to any one of a number of ASP.NET applications using only Windows Authentication (no Anonymous enabled), the system authenticates but our next layer of database-driven permissions prevents them from being authorized. We tracked it down to a mismatch of usernames between their logon account and who IIS thinks they are. Below are the outputs of several ASP.NET variables from apps running in a Windows 2008 IIS7.5 environment: Request.ServerVariables["AUTH_TYPE"]: Negotiate Request.ServerVariables["AUTH_USER"]: Domain\11111 Request.ServerVariables["LOGON_USER"]: Domain\22222 Request.ServerVariables["REMOTE_USER"]: Domain\11111 HttpContext.Current.User.Identity.Name: Domain\11111 System.Threading.Thread.CurrentPrincipal.Identity.Name: Domain\11111 From the above, I can see that only the LOGON_USER server variable has the correct value, which is the account the user used to log on to their machine. However, we use the "AUTH_USER" variable for looking up the database permissions. In a separate testing environment (completely different server: Windows 2003, IIS6), all of the above variables show "Domain\22222". So this seems to be a server-specific issue, like the credentials are somehow getting cached either on their machine or on the server (the former seems more plausible). So the question is: how do I confirm whether it's the user's machine or the server that is botching the request? How should I go about fixing this? I looked at the following two resources and will be giving the first one a try shortly: http://www.interworks.com/blogs/jvalente/2010/02/02/removing-saved-credentials-passwords-windows-xp-windows-vista-or-windows-7 http://stackoverflow.com/questions/2325005/classic-asp-request-servervariableslogon-user-returning-wrong-username/5299080#5299080 Thanks.

• Sync desktop Mac environment to laptop

  - by Andrew Vit

  I spend the majority of my time working at my desktop Mac, which I have configured for my web development environment. My spouse has a MacBook for casual use, and I occasionally steal it back when I need to work off-site, or when travelling. The question is how to best synchronize the two so I can switch between them more readily. I've solved a few obvious things by using online services: Email is hosted on IMAP. Working files are in Dropbox. Source code is managed in git. However, the following are things I always miss when jumping on the laptop: Installed Applications (current versions) Installed libraries & utilities (/usr/local) Apache VirtualHosts & other configurations (/etc) Disk image files for VMs My current method is to connect the MacBook via Firewire target mode and rsync the /Users/me home directory, and then cherry-pick the other items I need from Applications, /etc and /usr/local. The problem with this method is that it can be very time consuming due to things like my virtual machine image files, cached emails, etc. How can I make this faster & easier? Can you recommend a solution for configuration management (so I can repeatably install & configure the same software on both), or synchronization (so I can bring the MacBook up to date nightly, over our home network)?

• Why cache static files with Varnish, why not pass

  - by Saif Bechan

  I have a system runnning nginx / php-fpm / varnish / wordpress and amazon s3. Now I have looked at a lot of configuration files while setting up the system, and in all of them I found something like this: /* If the request is for pictures, javascript, css, etc */ if (req.url ~ "\.(jpg|jpeg|png|gif|css|js)$") { /* Remove the cookie and make the request static */ unset req.http.cookie; return (lookup); } I do not understand why this is done. Most of the examples also run NginX as a webserver. Now the question is, why would you use the varnish cache to cache these static files. It makes much more sense to me to only cache the dynamic files so that php-fpm / mysql don't get hit that much. Am I correct or am I missing something here? UPDATE I want to add some info to the question based on the answer given. If you have a dynamic website, where the content actually changes a lot, chaching does not make sense. But if you use WordPress for a static website for example, this can be cached for long periods of time. That said, more important to me is static conent. I have found a link with some test and benchmarks on different cache apps and webserver apps. http://nbonvin.wordpress.com/2011/03/14/apache-vs-nginx-vs-varnish-vs-gwan/ NginX is actually faster in getting your static content, so it makes more sense to just let it pass. NginX works great with static files. -- Apart from that, most of the time static content is not even in the webserver itself. Most of the time this content is stores on a CDN somewhere, maybe AWS S3, something like that. I think the varnish cache is the last place where you want to have you static content stored.

• Secure data from a server to a workstation using jumper hosts

  - by apalsson

  Hello. I have a WWW-server, my problem is that the content is sensitive and should not be accessible for people without proper credentials. How can I improve the ease of use but still maintain security following scenario; The Server is accessed through a "jumper host", i.e. the client connects to the jumper using VPN-connection and uses RemoteDesktop to access the jumper. From the jumper he uses RemoteDesktop again to access the Server. Finally on the Server the user can access content using a WWW-browser. All the way from the VPN-client to the WWW-browser requires authentication using a SmartCard-token. This seems quite secure to me. Content only gets mirrored on the RemoteDesktop between Server and jumper, no cached files to worry about. Connection between jumper and client is protected using VPN(ssl), so no eavesdropping. But it is quite cumbersome for the clients with many steps and connections to open. :( So, how can I improve the user experience accessing my server without compromising security? Thanks.

• Debian x86_64 + Nginx + PHP5-FPM optimization

  - by user55859

  I used to have a VPS (512MB) from Linode and I was running nginx + php5-fpm (which comes with php5.3.3) on Debian Lenny (i686). The total memory usage was about 90-100MB. Now I have another VPS (different hosting company) and I also run nginx + php5-fpm on Debian Lenny (x86_64). The system is 64-bit, so the memory usage is higher now, about 210-230MB, which I think is too much. Here is my php5-fpm.conf: pm = dynamic pm.max_children = 5 pm.start_servers = 2 pm.min_spare_servers = 2 pm.max_spare_servers = 5 pm.max_requests = 300 That's what top command tells me: top - 15:36:58 up 3 days, 16:05, 1 user, load average: 0.00, 0.00, 0.00 Tasks: 209 total, 1 running, 208 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 0.0%sy, 0.0%ni, 99.9%id, 0.1%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 532288k total, 469628k used, 62660k free, 28760k buffers Swap: 1048568k total, 408k used, 1048160k free, 210060k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 22806 www-data 20 0 178m 67m 31m S 1 13.1 0:05.02 php5-fpm 8980 mysql 20 0 241m 55m 7384 S 0 10.6 2:42.42 mysqld 22807 www-data 20 0 162m 43m 22m S 0 8.3 0:04.84 php5-fpm 22808 www-data 20 0 160m 41m 23m S 0 8.0 0:04.68 php5-fpm 25102 www-data 20 0 151m 30m 21m S 0 5.9 0:00.80 php5-fpm 10849 root 20 0 44100 8352 1808 S 0 1.6 0:03.16 munin-node 22805 root 20 0 145m 4712 1472 S 0 0.9 0:00.16 php5-fpm 21859 root 20 0 66168 3248 2540 S 1 0.6 0:00.02 sshd 21863 root 20 0 66028 3188 2548 S 0 0.6 0:00.06 sshd 3956 www-data 20 0 31756 3052 928 S 0 0.6 0:06.42 nginx 3954 www-data 20 0 31712 3036 928 S 0 0.6 0:06.74 nginx 3951 www-data 20 0 31712 3008 928 S 0 0.6 0:06.42 nginx 3957 www-data 20 0 31688 2992 928 S 0 0.6 0:06.56 nginx 3950 www-data 20 0 31676 2980 928 S 0 0.6 0:06.72 nginx 3955 www-data 20 0 31552 2896 928 S 0 0.5 0:06.56 nginx 3953 www-data 20 0 31552 2888 928 S 0 0.5 0:06.42 nginx 3952 www-data 20 0 31544 2880 928 S 0 0.5 0:06.60 nginx So, the question is there any way to use less memory?

• Poor performance on IIS7, only on Windows Server 2008, fine on Windows 7?

  - by user32005

  Hi, I'm new to IIS7 but have experience with other versions. I've been working on an application that works great in a dev environment (as always) but when I push it to a windows server 2008/IIS7 box performance takes a noticeable hit. The dev environment is Windows7/IIS7. The configuration in IIS is the same on the dev box as the server. I've tried all sorts of things to try and find a reason for this but I cant come to any conclusion. I've ruled out database problems on the live box as all data is cached after the first request. I've confirmed this to be true and made sure there is no additional database traffic. I've ruled out network issues with a combination of monitoring requests with fiddler and local debugging on the server. Whenever the code runs on the server there seems to be a performance issue. The server: Intel Core 2 Quad CPU Q6600 @ 2.40ghz with 2gb RAM. I know this is not fantastic but I was expecting it to at least perform as well as my dev environment (which is running much more on a lower spec). The CPU using peaks at under 60%, and memory usage is less than half of the available. I've enabled failed request tracing and most of the time is spent in a custom HttpModule, this module works to handle every request, I cant get any more detail as to what within the module may be causing the problem. Any ideas, I've been pulling my hair out for days now. Thanks

• Outlook 2010 not resolving SMTP address to Display Name

  - by Ben

  I have a weird problem where a user (director, naturally) has an odd problem with the way the to field shows in his Outlook. We are using Outlook 2010 (with RPC/HTTP) and Exch 2003 at the back end. Most of his mail shows in his mailbox with the To: field as normal. (e.g. Fred Bloggs in the to field.) However, some mails come in showing in the To: field as [email protected]. (Apparently this is an issue!) For example, most show as: but a few come in as: There doesn't appear to be a pattern to this. I have tried to replicate by: Sending from any specific senders to see if it recurs (it doesn't) Typing his full name in my Outlook and sending (it resolves as normal) Sending programatically (e.g. from script) - (it still resolves OK) Forcing a "[email protected]" entry in my Outlook. It resolves as soon as I hit enter Sending in cached mode Sending disconnected Anyone got any ideas how I can either replicate the problem or fix it! I can't tell at the moment whether it is a problem at his end or the sender's. EDIT This seems to be a global issue, following some more digging. Most people seem to have a few emails in their inbox addressed to their smtp address, rather than display name.

• TOR Proxy / Vidalia "New Identity" button not working

  - by Yisman

  I need to hide my ip from time to time. In Vidalia, I click on "New Identity". Ihen I check http://myip.ozymo.com/ to see if my IP address has changed. But, no, it hasn't. Why is that? And how can this be fixed? I tried waiting till the button gets re-enabled to make sure that its done processing the command, but still the IP address is the same. In Fiddler each request is tracked, so it's not a cached response. It's re-requested, but simply does not change. Fiddler though does show one thing interesting. Here is the raw response of many of the requests: HTTP/1.1 200 OK Content-Length: 13 Date: Mon, 23 May 2011 12:02:57 GMT Server: Apache X-Powered-By: PHP/5.2.14 Content-Type: text/html; charset=UTF-8 Age: 1 Connection: keep-alive **Warning: 110 localhost:8118 Object is stale** 26.32.120.106 What is this warning? And is this the cause?

• S.M.A.R.T. broken sectors

  - by Jeffrey Vandenborne

  Recently I received my hard drive (LaCie) that I've sent away for warranty, my disk failed, and I used Palimpsest Disk utility to check if anything was wrong in the S.M.A.R.T Status. And it said that there were a few broken sectors. So the next day, I went to the store and told the story. 4 weeks later I actually got my drive back. The first thing I did was plugging it in and starting the disk utility, and weirdly it showed me pretty much the exact same things, even the values of most tests were the same as they were before when my drive broke. The serial number is different though, but it does show a very peculiar value. Now I'm wondering, I'm almost sure it's the exact same drive and it still says I've got broken sectors, does it just say that because it has been cached in the drive somewhere while LaCie DID actually fix it? Or should I run the extended self test (which seems to take hours) first? Also I've tried the smartctl command tool, it says the drive has smart support, but it doesn't show anything, it says that it's enabled, but then it says that it's disabled, picture below The picture of the Disk utility: Thanks in advance

• Browsing \\computer\share fails, but net use \\computer\share works?

  - by JMD

  I've had mixed results with using Windows Explorer to browse remote file shares. The setup: I'm at work on Windows XP SP3 Files are at home on Windows XP SP3 Two separate VPNs are available to access my PC at home corporate OpenVPN (10.1.2.3) a Hamachi/LogMeIn connection (5.1.2.3) With respect to my problem, it doesn't matter which IP I use. They both perform exactly the same way: I expect that if I open Windows Explorer and type in \\10.1.2.3\Shared I should be interrupted with a challenge for credentials, and then be able to interact with the files in the share. However, I just get that annoying dialog, "Windows cannot find '\10.1.2.3\Shared' Check the spelling and try again, or try searching for the item ..." However, I can take that exact same computername/sharename and with net use I can: net use * \\10.1.2.3\Shared * /user:homecomputername\username with this result: Type the password for \\5.69.83.158\C$: Drive Z: is now connected to \\5.69.83.158\C$. The command completed successfully. I can then access the files in Z: in Windows Explorer which was my original intent. Even after Z: is already mapped and the credentials are cached I still cannot bring up \\10.1.2.3\Shared in Windows Explorer. Why does the latter work, but not the former? Edit: Other services work fine, such as RDP. (I have a problem in which I can't SSH home, but I'll consider that separately.)

• Having trouble keeping a 1GB RAM Centos server running

  - by Josh

  This is my first time configuring a VPS server and I'm having a few issues. We're running Wordpress on a 1GB Centos server configured per the internet (online research). No custom queries or anything crazy but closing in on 8K posts. At arbitrary intervals, the server just goes down. From the client side, it just says "Loading..." and will spin more or less indefinitely. On the server side, the shell will lock completely. We have to do a hard reboot from the control panel and then everything is fine. Watching "top" I see it hovering between 35 - 55% memory usage generally and occasional spikes up to around 80%. When I saw it go down, there were about 30 - 40 Apache processes showing which pushed memory over the edge. "error_log" tells me that maxclients was reached right before each reboot instance. I've tried tinkering with that but to no avail. I think we'll probably need to bump the server up to the next RAM level but with ~120K pageviews per month, it seems like that's a bit overkill since it was running fairly well on a shared server before. Any ideas? httpd.conf and my.cnf values to add? I'll update this with the current ones if that helps. Thanks in advance! This has been a fun and important learning experience but, overall, quite frustrating!

• Server 2003 and SSL Certificates

  - by Keith Stokes

  I have a Windows 2000 domain with dozens of Windows 2000 servers and a few 2003 servers. Each server runs a custom app talking to a 3rd party utilizing self-signed certificates. To help troubleshooting we've created a custom test app. The 2000 servers are able to talk within seconds. The 2003 servers take anywhere from 10-30 seconds using a domain account and much less, usually under 5 seconds using a local account. The only exception to the local account performance is a new account, which is slow initially then faster. If you leave the test app open and reconnect repeatedly it talks in seconds. If you leave it open for sometime between 1 and 2 hours, it reverts back to the previous 10 seconds, so obviously something is caching. Installing the destination certificates in the local 2003 server store makes no difference. I've installed the certificates in AD and that apparently makes domain accounts work in 9-12 seconds, vs 30 seconds that was regular before. Manually clearing the certificate store on the 2003 server makes no difference. I'm at a loss as to where the certs might be cached and if I'm using some sort of domain certificate store that's hiding from me.

• How can I use wildcards in an Nginx map directive?

  - by Ian Clelland

  I am trying to use Nginx to served cached files produced by a web application, and have spotted a potential problem; that the url-space is wide, and will exceed the Ext3 limit of 32000 subdirectories. I would like to break up the subdirectories, making, say, a two-level filesystem cache. So, where I am currently caching a file at /var/cache/www/arbitrary_directory_name/index.html I would store that instead at something like /var/cache/www/a/r/arbitrary_directory_name/index.html My trouble is that I can't get try_files, or even rewrite to make that mapping. My searching on the subject leads me to believe that I need to do something like this (heavily abbreviated): http { map $request_uri $prefix { /aa* a/a; /ab* a/b; /ac* a/c; ... /zz* z/z; } location / { try_files /var/cache/www/$prefix/$request_uri/index.html @fallback; # or # if (-f /var/cache/www/$prefix/$request_uri/index.html) { # rewrite ^(.*)$ /var/cache/www/$prefix/$1/index.html; # } } } But I can't get the /aa* pattern to match the incoming uri. Without the *, it will match an exact uri, but I can't get it to match just the first two characters. The Nginx documentation suggests that wildcards should be allowed, but I can't see a way to get them to work. Is there a way to do this? Am I missing something simple? Or am I going about this the wrong way?

• How can I avoid permission denied errors when attempting to deploy a rails app with capistrano?

  - by joshee

  Total noob here. I'm attempting to deploy an app through Capistrano. I'm getting relentless permission denied errors when I attempt to run cap deploy:update. Seemingly at least some of these errors are due to missing directories that trigger a "Permission Denied" error.

• Caching/preloading files on Linux into RAM

  - by Andrioid

  I have a rather old server that has 4GB of RAM and it is pretty much serving the same files all day, but it is doing so from the hard drive while 3GBs of RAM are "free". Anyone who has ever tried running a ram-drive can witness that It's awesome in terms of speed. The memory usage of this system is usually never higher than 1GB/4GB so I want to know if there is a way to use that extra memory for something good. Is it possible to tell the filesystem to always serve certain files out of RAM? Are there any other methods I can use to improve file reading capabilities by use of RAM? More specifically, I am not looking for a 'hack' here. I want file system calls to serve the files from RAM without needing to create a ram-drive and copy the files there manually. Or at least a script that does this for me. Possible applications here are: Web servers with static files that get read alot Application servers with large libraries Desktop computers with too much RAM Any ideas? Edit: Found this very informative: The Linux Page Cache and pdflush As Zan pointed out, the memory isn't actually free. What I mean is that it's not being used by applications and I want to control what should be cached in memory.

• High fan speed with no reason

  For a few weeks, the fans of my Lenovo B590 laptop, running on Xubuntu 14, turn to high speed a few minutes after it is turned on. The fans won't speed down until I turn the computer off. This is quite strange, since This didn't happen before The temperatures are quite low (are they ?) $sensors Adapter: Virtual device temp1: +36.0°C (crit = +88.0°C) temp2: +30.0°C (crit = +126.0°C) coretemp-isa-0000 Adapter: ISA adapter Physical id 0: +37.0°C (high = +72.0°C, crit = +90.0°C) Core 0: +34.0°C (high = +72.0°C, crit = +90.0°C) Core 1: +31.0°C (high = +72.0°C, crit = +90.0°C) thinkpad-isa-0000 Adapter: ISA adapter fan1: 0 RPM pkg-temp-0-virtual-0 Adapter: Virtual device temp1: +37.0°C $sudo hddtemp /dev/sda /dev/sda: ST500LT012-9WS142: 33°C The computer is under low load: top - 08:30:15 up 16 min, 2 users, load average: 0.28, 0.23, 0.23 Tasks: 197 total, 1 running, 196 sleeping, 0 stopped, 0 zombie %Cpu(s): 0.8 us, 0.5 sy, 0.0 ni, 98.7 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st KiB Mem: 3607944 total, 1973956 used, 1633988 free, 99660 buffers KiB Swap: 3744764 total, 0 used, 3744764 free. 789936 cached Mem The BIOS is up to date (and there are no fan settings in it) The fan is clean and dust-free Why would the BIOS turn the fans to high speed where there seem to be no reason for that ? It seems that we cannot control the fan manually with this model, so I guess the only solution is to understand why this happens.

• VPS Memory Exchausted Even With Light Settings

  - by user101570

  Linux noob here. I have a 256MB VPS on Ubuntu 11.04 server and when I run "free -m" the result shows all memory being used (including the second line re: buffers/cache). I found this very strange, considering I only have 5 Apache processes running each chewing up about 20MB each. MYSQL is taking up 30MB. To my knowledge, and according to "top", I have no other memory hogs operating. Settings that may be relevant: PHP memory_limit = 32M MYSQL key_buffer = 16M Prefork MPM Maxclients = 10 So when I reviewed these settings, I naturally thought maxclients was too high, so I tried switching it to 5. Now not only does my memory still show as being 100% used, my website loads much, much slower, despite not getting any traffic aside from mine at the moment. I don't understand this. I thought a single Apache process handles all requests from a client received within the "KeepAliveTimeout" window, which I've set to 2 seconds. With my initial config. of 10 maxclients, my page load times are around .3ms, so a single process should handle that no problem, correct? So next I went to an extreme level of 1 for maxclients. My memory is still at 100% usage and my site loads painfully slow. I'm a noob at a complete loss here. According to the many tutorials I've read on basic server setup, I should be good to go. Help! Please! Edit: total used free shared buffers cached Mem: 256 256 0 0 0 0 -/+ buffers/cache: 256 0 Swap: 0 0 0

• Nginx + WordPress + HHVM: Why isn't Batcache working? Would Varnish help even more?

  - by javipas

  I've heard great things about HHVM, so I've setup a copy of WordPress blog (on another domain) with Nginx (with the Pagespeed module) and HHVM. Right now the benefits are obvious: on the same config, load times are between two and three times faster. I'm trying to speed up things a little bit, and I've also installed Memcached and Batcache. I've installed the memcached package, copied object-cache.php (Pastebin) onto the root folder of the WordPress blog, and after that I've installed the Batcache plugin and copied the advanced-cache.php (Pastebin) file onto the wp-content folder. Also, I've included the line define('WP_CACHE', true); in the wp-config.php file. It seems it doesn't work, though. If I quickly reload the page several times Batcache should show the cached page, but it doesn't. It's easy to check that by reloading (Cmd+R on Chrome on OS X) the page several times and then viewing the page's code. Under the <head> section I should see some batcache stats, but they aren't there. I wonder if someone could give me some hint on this. On a side note, I don't know if I could add some other component in order to help the performance be even better. I'm thing about Varnish, but I'm not sure if it's just useless and it's just another way to the same I'm currently doing. Any other component there? (I'll test CDN for images, minifying js, etc and some other tricks as well, but I'm talking from the server perspective).

• Centos 6.2 postfix install dependency issues

  - by Mishari

  I am administrating a VPS running cPanel and I'm trying to install postfix. Redhat-release says the version is CentOS release 6.2 (Final) and uname -a says: Linux server.mydomain.com 2.6.32-220.el6.i686 #1 SMP Tue Dec 6 16:15:40 GMT 2011 i686 i686 i386 GNU/Linux This is how I'm installing postfix (I had tried to solve the problem earlier by installing epel). # yum install postfix Loaded plugins: fastestmirror, security Loading mirror speeds from cached hostfile * epel: mirror.cogentco.com Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package postfix.i686 2:2.6.6-2.2.el6_1 will be installed --> Processing Dependency: mysql-libs for package: 2:postfix-2.6.6-2.2.el6_1.i686 --> Finished Dependency Resolution Error: Package: 2:postfix-2.6.6-2.2.el6_1.i686 (centos-burstnet) Requires: mysql-libs You could try using --skip-broken to work around the problem Attempts to install mysql-libs tells me several files conflict with "MySQL-server-5.1.61-0.glibc23.i386" I'm not sure why or how this is happening, does anyone know how to resolve this? Surely Centos 6.2 could not have shipped with a broken postfix.

• Why is my cron daemon is being killed every few minutes?

  - by user113215

  As of about a week ago, my cron daemon refuses to stay running. I'm using Debian 6 x64 on an OpenVZ virtual machine. Running something like pgrep cron shows that the daemon isn't running. I start the service with service cron start or /etc/init.d/cron start and it launches, but it disappears from the running process list after a few minutes (varying anywhere between 1 - 30 minutes before the process is killed again). Using strace -f service cron start, I can see that the process is being killed for some reason: nanosleep({60, 0}, <unfinished ...> +++ killed by SIGKILL +++ There's nothing relevant in /var/log/syslog, /var/log/messages, /var/log/auth.log, or /var/log/kern.log to explain why the the process is dying. The system has at least 800 MB of free memory, and cat /proc/loadavg returns 0.22 0.13 0.04 so resources shouldn't be the issue. With cron running, free -m reports: total used free shared buffers cached Mem: 1024 211 812 0 0 0 -/+ buffers/cache: 211 812 Swap: 0 0 0 I also tried removing and reinstalling the cron package using apt-get. Update: I initially thought the problem was a resource issues. I erased my entire VPS and started from a fresh Debian image. There is now nothing else running on the system, but even from a clean install my cron daemon is still being killed at random. What else should I check? How do I find out what's killing my crond?

• nginx giving of 404 when using set in an if-block

  - by ba

  I've just started using nginx and I'm now trying to make it play nice with the Wordpress plugin WP-SuperCache which adds static files of my blog posts. To serve the static file I need to make sure that some cookies aren't set, that it's not a POST-request and making sure the cached/static file exist. I found this guide and it seems like a good fit. But I've noticed that as soon as I try to set something inside an if my site starta giving 404s on an URL that isn't rewritten. The location block of the configuration: location /blog { index index.php; set $supercache_file ''; set $supercache_ok 1; if ($request_method = POST) { set $supercache_ok 0; } if ($http_cookie ~* "(comment_author_|wordpress|wp-postpass_)") { set $supercache_ok '0'; } if ($supercache_ok = '1') { set $supercache_file '$document_root/blog/wp-content/cache/supercache/$http_host/$1/index.html.gz'; } if (-f $supercache_file) { rewrite ^(.*)$ $supercache_file break; } try_files $uri $uri/ @wordpress; } The above doesn't work, and if I remove all the ifs above and add if ($http_host = 'mydomain.tld') { set $supercache_ok = 1; } and then I get the exact same message in the errors.log. Namely: 2010/05/12 19:53:39 [error] 15977#0: *84 "/home/ba/www/domain.tld/blog/2010/05/blogpost/index.php" is not found (2: No such file or directory), client: <ip>, server: domain.tld, request: "GET /blog/2010/05/blogpost/ HTTP/1.1", host: "domain.tld", referrer: "http://domain.tld/blog/" Remove the if and everything works as it should. I'm stymied, no idea at all where I should start searching. =/ ba@cell: ~> nginx -v nginx version: nginx/0.7.65

• OpenVZ: Choosing right MySQL-Server depending on host

  - by Scheintod

  What I have: Two servers running Wheezy/OpenVZ with One MySQL container on each host master/master replicated (mysql1/mysql2) Replicated DNS on each host (dns1/dns2) different web-containers on each host but regulary backuped to the other. What I want: Each container should use the "local" MySQL-Server (the one which runs on the same hardware-node). I'd like to be able to move the web-containers between the to hosts. Each container should choose the MySQL-Server (semi) automatically. This scheme should continue working if one host is down. What I tried: Currently I'm keeping track on which container should run on which host by DNS entries which are queries by scripts e.g. for questions like: "Which container should be backuped on/to which host." For choosing the right MySQL server I have one extra entry like "mysql.container_abc" which resolves to either mysql1/mysql2. So in the applications in the container I can use "mysql.container_abc" for e.g. mysql_connect and if I want to move the container around I just need to change the dns. Now I notices one problem with this approach: Every mysql_connect generates one DNS query because the dns is not cached and this slows the request down unnecessarily. What I would like better: Some way of passing the information on which host we are running to the container and using it directly instead of using DNS. E.g. some way of setting a custom /etc/hosts entry in the container. Or any other great idea. Doesn't have to include DNS but shouldn't require to much special "magic" inside the container.
