• swapping or trashing with vast amounts of unmapped pagecache

  - by Marco

  I'm using kubuntu jaunty (i386 32bit), kernel 2.6.28-13-generic. I've 4Gb of RAM, of which only 3317Mb are seen by the system (I guess because of the 32bit system). I'm seeing that the pagecache utilization is continually growing, up to the point that the system is unusable (after a few days). This happens also when I don't do anything (all user applications closed and the bare minimum of services enabled). If enabled, the system starts to use swap space (using it all in the end). Even if swap is disabled, disk activity becomes continuous, with the system unresponsive. For example, right now the system is working (albeit a tad slow), with only firefox and wing ide running, and I have 2Gb cached with only 45Mb mapped: $ free total used free shared buffers cached Mem: 3346388 3247328 99060 0 8416 2117980 -/+ buffers/cache: 1120932 2225456 Swap: 2144668 519448 1625220 $ cat /proc/meminfo MemTotal: 3346388 kB MemFree: 97128 kB Buffers: 7872 kB Cached: 2120224 kB SwapCached: 413860 kB Active: 2304596 kB Inactive: 865984 kB Active(anon): 2279168 kB Inactive(anon): 830236 kB Active(file): 25428 kB Inactive(file): 35748 kB Unevictable: 32 kB Mlocked: 32 kB HighTotal: 2492940 kB HighFree: 5456 kB LowTotal: 853448 kB LowFree: 91672 kB SwapTotal: 2144668 kB SwapFree: 1625244 kB Dirty: 84 kB Writeback: 0 kB AnonPages: 629304 kB Mapped: 45768 kB Slab: 45600 kB SReclaimable: 21756 kB SUnreclaim: 23844 kB PageTables: 4468 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 3817860 kB Committed_AS: 3735020 kB VmallocTotal: 122880 kB VmallocUsed: 9352 kB VmallocChunk: 66600 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 4096 kB DirectMap4k: 16376 kB DirectMap4M: 888832 kB If I try to drop the caches, little happes: # sync ; echo 3 > /proc/sys/vm/drop_caches ; free total used free shared buffers cached Mem: 3346388 3220580 125808 0 3020 2100600 -/+ buffers/cache: 1116960 2229428 Swap: 2144668 519356 1625312 Right now I've vm.swappiness = 5, but I've tried also with 0 and 1 (without noticeable differences).

• How to troubleshoot web server lock-up (Debian Squeeze)

  - by Ryan

  Every once in a while, my web server slows so significantly, it seems locked up. Can't SSH in, no sites being served. It's a VPS that started out as Debian 5 which I upgraded to testing (squeeze). It's a typical LAMP set-up with the sole purpose of running a couple of wordpress sites. One time when it locked up, I got to one of the sites, but it was wordpress complaining it couldn't establish a database connection. So it seemed as if something was really chewing up the CPU and mysqld either timed out, or possibly failed and couldn't restart. But since I couldn't SSH in I feel more inclined to attribute it to CPU. But the only processes running now, aside from OS and kernel stuff: apache mysqld python (for fail2ban) sshd exim4 It has 512M of RAM and 1.5 GB of swap. Every time I check on it, it has plenty of free memory and is using virtually no swap (usually 2-3M). And since I am running fail2ban I don't think I'm getting ddosed. I did find this in my logwatch email this morning (it locked up late last night, when there would have been very little traffic): 6 Time(s): [<ffffffff810a0ebc>] ? oom_kill_process+0x7e/0x23d 6 Time(s): [<ffffffff810a1505>] ? __out_of_memory+0x12a/0x141 6 Time(s): [<ffffffff810a1586>] ? out_of_memory+0x6a/0x94 I didn't find anything else suspicious. It can't be my provider's host because I can SSH in and restart the VM, and everything seems fine. Anybody know which logs I should start poring through to find the core of my problem? Thanks guys.

• Have set Expiration time: Still getting "Query string present but no explicit expiration time"

  - by oligofren

  I have one local Apache instance running with mod_cache (+ disk & mem) enabled, and it seems to cache content from my appserver fine. My app server sets Expiration headers and Last-modified. Yet, when deploying on a production server with the same modules enabled, I am getting the following error in my logs: blablabla not cached. Reason: Query string present but no explicit expiration time Any clues on why Apache is not caching content? The only difference is the Apache version. Locally I am running 2.2. This is from my config CacheRoot "/var/cache/apache2/" CacheEnable disk / This is example output < HTTP/1.1 200 OK < Date: Mon, 19 Nov 2012 16:09:13 GMT < Server: Sun GlassFish Enterprise Server v2.1.1 < X-Powered-By: Servlet/2.5 < Expires: Tue Nov 20 05:00:00 CET 2012 < Last-Modified: Mon Nov 19 17:09:13 CET 2012 < Cache-Control: no-transform < Content-Type: application/x-javascript < Transfer-Encoding: chunked

• How to import certificate for Apache + LDAPS?

  - by user101956

  I am trying to get ldaps to work through Apache 2.2.17 (Windows Server 2008). If I use ldap (plain text) my configuration works great. LDAPTrustedGlobalCert CA_DER C:/wamp/certs/Trusted_Root_Certificate.cer LDAPVerifyServerCert Off <Location /> AuthLDAPBindDN "CN=corpsvcatlas,OU=Service Accounts,OU=u00958,OU=00958,DC=hca,DC=corpad,DC=net" AuthLDAPBindPassword ..removed.. AuthLDAPURL "ldaps://gc-hca.corpad.net:3269/dc=hca,dc=corpad,dc=net?sAMAccountName?sub" AuthType Basic AuthName "USE YOUR WINDOWS ACCOUNT" AuthBasicProvider ldap AuthUserFile /dev/null require valid-user </Location> I also tried the other encryption choices besides CA_DER just to be safe, with no luck. Finally, I also needed this with Apache tomcat. For tomcat I used the tomcat JRE and ran a line like this: keytool -import -trustcacerts -keystore cacerts -storepass changeit -noprompt -alias mycert -file Trusted_Root_Certificate.cer After doing the above line ldaps worked greate via tomcat. This lets me know that my certificate is a-ok. Update: Both ldap modules are turned on, since using ldap instead of ldaps works fine. When I run a git clone this is the error returned: C:\Tempgit clone http://eqb9718@localhost/git/Liferay.git Cloning into Liferay... Password: error: The requested URL returned error: 500 while accessing http://eqb9718@loca lhost/git/Liferay.git/info/refs fatal: HTTP request failed access.log has this: 127.0.0.1 - eqb9718 [23/Nov/2011:18:25:12 -0600] "GET /git/Liferay.git/info/refs service=git-upload-pack HTTP/1.1" 500 535 127.0.0.1 - eqb9718 [23/Nov/2011:18:25:33 -0600] "GET /git/Liferay.git/info/refs HTTP/1.1" 500 535 apache_error.log has nothing. Is there any more verbose logging I can turn on or better tests to do?

• mod_perl loses STDOUT in middle of request

  - by puzzled72

  Hi, I have been having this weird issue where mod_perl seems to lose STDOUT in the middle of the request. So far I have eliminated everything I could think of. You might have seen this bug related to the following errors in error_log : Apache2 IO flush: (103) Apache2::RequestIO::read: (104) Software caused connection abort They are all the same error. It happens when the perl script running under mod_perl loses STDOUT when trying to print the result back to apache. I only notice this error on my servers running the following: (centos5.4) Perl 5.8.8-27 mod_perl 2.0.4-6 httpd 2.2.3-31 kernel-2.6.18-164.15.1 It's not the code This code has been working for months It's not network related The browser gets the error response from apache. It's not time related I get the error 15 or so seconds after I restart httpd It's not idle httpd related I have tried reducing the min/max SpareServers to 1 It's not load related I get the error even if there are only 10 sessions on httpd It's not related to the "fd < PERLIO_MAX_REFCOUNTABLE_FD" perl 5.8.8 bug I recompiled perl-5.8.8 with the patch mentioned here : https://bugzilla.redhat.com/show_bug.cgi?id=559832, same error. It appeared sometime between December 2009 and February 2010 sorry I cannot be more specific Anyone has any idea ? Anything that I have not tested ? Really Puzzled!

• Linux AMD-FX 8350 temperature monitoring

  - by HyperDevil

  I’m trying to get the CPU temperature for my AMD-FX8350 on Debian Squeeze. I ran sensors-detect and then sensors, but I only get my motherboard sensors (it8720-isa-0228). There are three temperature values there but I assume those are not for the CPU. it8720-isa-0228 Adapter: ISA adapter in0: +1.36 V (min = +0.00 V, max = +4.08 V) in1: +1.50 V (min = +0.00 V, max = +4.08 V) in2: +3.38 V (min = +0.00 V, max = +4.08 V) in3: +2.93 V (min = +0.00 V, max = +4.08 V) in4: +3.07 V (min = +0.00 V, max = +4.08 V) in5: +4.08 V (min = +0.00 V, max = +4.08 V) in6: +4.08 V (min = +0.00 V, max = +4.08 V) in7: +2.93 V (min = +0.00 V, max = +4.08 V) Vbat: +3.01 V fan1: 3375 RPM (min = 10 RPM) fan2: 0 RPM (min = 0 RPM) fan3: 1730 RPM (min = 10 RPM) fan5: 0 RPM (min = 0 RPM) temp1: +27.0°C (low = +127.0°C, high = +127.0°C) sensor = thermistor temp2: +53.0°C (low = +127.0°C, high = +127.0°C) sensor = thermal diode temp3: +65.0°C (low = +127.0°C, high = +90.0°C) sensor = thermal diode cpu0_vid: +0.000 V Is there anything I am missing?

• CloneZilla PXE Boot Without NFS

  - by John

  I am trying to setup CloneZilla to be bootable via PXE without using NFS. I do not have NFS running on our PXE server and would like to keep it that way. However, most of the information that I have found online indicates that you need to setup NFS in order to PXE boot CloneZilla. I believe that I am pretty close in getting it to work, but am not sure where to go next. Listed below are the different PXE menu option configurations that I have used so far. LABEL Clonezilla Live MENU LABEL Clonezilla Live KERNEL utilities/clonezilla/vmlinuz APPEND initrd=utilities/clonezilla/initrd.img boot=live live-config noswap nolocales edd=on nomodeset ocs_live_run="ocs-live-general" ocs_live_extra_param="" ocs_live_keymap="" ocs_live_batch="no" o$ I have also tried the following append lines, without success: APPEND initrd=utilities/clonezilla/initrd.img boot=live union=aufs noswap noprompt vga=788 fetch=tftp://10.130.155.23/filesystem.squashfs APPEND initrd=utilities/clonezilla/initrd.img boot=live union=aufs noswap noprompt vga=normal nomodeset nosplash fetch=tftp://10.130.155.23/filesystem.squashfs Each of them have resulted in a no go with the following error: "Unable to find a live file system on the network". It looks like it gets to the point of trying to load the filesystem.squashfs file, hangs, and then throws the error. Any help would be greatly appreciated.

• Cisco ASA Act as a Hardware Security Module?

  - by Derek

  Hello, We have a partner that is requiring us to get a HSM for a web application that we host for them. This is something new for us, we've always installed our SSL certificates on our web servers and never needed a hardware device. We currently have 2 Cisco ASA 5510 firewalls in an active/standby configuration. Both ASAs have a ASA-SSM-10 security module installed in them. The web application is a standard HTTPS webpage with no authentication required. I was wondering if we could use our Cisco ASAs to meet this requirement or if we'll have to buy another device. I was doing some searching and read about Cisco's clientless webvpn feature. It sounds like it might work, but I'm not sure. We basically want the ASA to handle the SSL and proxy the connection to our web servers. We do not want to prompt for a username or password to connect or show any portals, just display the web page. If the ASA cannot do this, does any one have any recommendations for network attached hardware security modules? We are using VMware vCenter, so we'd rather have an external device attached to the network, rather than buying HSM cards for every ESXi host. Thanks, Derek

• Problems during an update of cPanel / WHM

  - by haron

  I ordered a Master WHM account with the couple CentOS / cPanel. whm-cpanel.eu.pn The installation is a fresh update of the basic services was necessary (had: WHM 11.15.0 cPanel 11.17.0 WHM X v3.1.0, Apache 1.3.37, PHP 4.4.7, MySQL 4.1.22). 1 / I started to update cPanel / WHM via the command: / scripts / upcp. Everything went well until the middle of installing the server stopped responding (or ping, or ssh). The installation appears to have continued alone to the end and after some time everything is back to normal (I do not know if there was a reboot) and my interface was updated (cPanel 11.24.4-R36167 - WHM 11.24.2 - X 3.9). 2 / Then I updated via the MySQL interface tweak this in WHM then the command: / scripts / mysqlup. Here everything went fine, no problem. 3 / Finally, I wanted to upgrade Apache 2.2 / PHP 5 and I used this command: / scripts / easyapache. After selecting all the packages and modules installation is started but the same as for point 1: the server did not answer more and this time the installation did not go through. Apache 2.2 is well spent (after the second try) but PHP has remained at 4. I tried several times the same operation without success. I do not think this is a memory problem, a free-m shortly before losing communications gave nothing alarming. By cons CPU time seemed to rise up. I reinstalled the machine again the trick, same problem! Whether via the WHM interface or by Shell, the installation stops short, for 15 minutes the machine is not responding and then everything returns to normal, but no update is done in PHP. Is there a known bug in this version of cPanel / WHM? Someone he met the same problem? If I compile Apache / PHP manually, without using the script easyapache is what I might encounter problems with cPanel later? Thank you!

• Webmin / Virtualmin running php as www-data, is locked out of viewing .htaccess and writing

  - by Kirill

  I've asked this on the virtualmin forums, but haven't had any help from there. Recently, "something" happened and it seems that the apache service has gone a bit weird. What it does: it runs all apache traffic as www-data and sometimes spawns the php5-cgi process as www-data, this is a problem because all the domain users own their directories and default permissions don't let www-data write to these folders (file uploads are dead) or read .htaccess (permalinks are broken in wordpress). I've googled this for about a week straight now, tried pretty much everything I could find and achieved nothing. The only thing that I think might actually be the cause of all this is this page: http:// - i.imgur.com/NYW3x.png (got shut down by the spam filter) So I figured if I set it to "default", this might magically start working again, but all it does is "crash" apache (all websites timeout). I figure it's something to do with the "mpm" module or something, but I can't find anything relevant in the settings to modify for it to work. Can someone please point me in the right direction? System info: Webmin version 1.580 Kernel and CPU Linux 2.6.35.4-rscloud on x86_64 Virtualmin version 3.90.gpl GPL Ubuntu 10.04 LTS (Lucid) A couple screenshots of top http://i.imgur.com/U2DTK.png http://i.imgur.com/sNPKs.png

• Reverse proxy for mailserver (SMTP + HTTP for web client)

  - by gaqzi

  I'm looking at doing some reverse proxy work for a mail server with corresponding web client. Both servers are running on the same machine, this is not a server with a high load. :) The solution I've discussed with friends is having the mail server/web client on our internal network. Then to put a reverse proxy on the DMZ to service both SMTP and web client HTTP-traffic to the mail server on the internal network. From what I understand this is the recommended secure solution? So far I've thought for the SMTP-proxy part of using postfix which will receive mail, do some spamhause and similar anti-spam measures and if it all checks out, send the mail to the mail server on the inside. The mail server on the inside will send all outgoing mail to the proxy which will then send it out on the Internet. For the web client I'm not sure exactly which software I should be running on the proxy machine, I've been thinking about using Squid -- but that's basically based on the fact that I know squid is a http proxy. The web client data will be sent out over SSL. Reading around some here on Serverfault I've seen other people using Apache with mod_proxy+mod_security for similar situations. Am I thinking correctly for this solution? What software would you guys use and with which modules? Thanks in advance for the help! :)

• ICMP Redirect Theory VS. Application

  - by joeqwerty

  I'm trying to watch ICMP redirects in a lab using Cisco Packet Tracer (version 5.3.2) and I'm not seeing them, which leads me to believe that either my lab configuration isn't correct or my understanding of ICMP redirects isn't correct or that Packet Tracer doesn't support/use ICMP redirects. Here's what I believe to be true regarding ICMP redirects: Routers send ICMP redirects when all of these conditions are met: The interface on which the packet comes into the router is the same interface on which the packet gets routed out. The subnet or network of the source IP address is on the same subnet or network of the next-hop IP address of the routed packet. The datagram is not source-routed. The router kernel is configured to send redirects. I have the lab set up in Cisco Packet Tracer as displayed in the image and would expect to see an ICMP redirect from Router1 when pinging from PC1 to PC3. I'm not seeing the ICMP redirect and it looks like Router1 is actually routing all of the packets via Router2. I have IP ICMP debugging enabled on Router1 (and Router2) and I'm not seeing any ICMP redirect activity in either console. I'm also not seeing a route to the PC3 network in the routing table on PC1, which I think confirms that the ICMP redirect is not occurring. I'm using only static routing on Routers 1 and 2. Is my understanding of ICMP redirects incorrect, or is there a problem with my lab configuration or does Packet Tracer not support/use ICMP redirects?

• APC + FPM memory fragmentation without a reason

  - by palmic

  My setup @ debian 6-testing is: nginx 1.1.8 + php 5.3.8 + php-fpm + APC 3.1.9 Because i use automatic deployment with apc_clear_cache() after deploy, my target is to set up APC to cache all my project (up to 612 php files smaller than 1MB) without files changes checking. My confs: FPM: pm.max_children = 25 pm.start_servers = 4 pm.min_spare_servers = 2 pm.max_spare_servers = 10 pm.max_requests = 500 APC: pc.enabled="1" apc.shm_segments = 1 apc.shm_size="64M" apc.num_files_hint = 640 apc.user_entries_hint = 0 apc.ttl="7200" apc.user_ttl="7200" apc.gc_ttl="600" apc.cache_by_default="1" apc.filters = "apc\.php$,apc_clear.php$" apc.canonicalize="0" apc.slam_defense="1" apc.localcache="1" apc.localcache.size="512M" apc.mmap_file_mask="/tmp/apc-php5.XXXXXX" apc.enable_cli="0" apc.max_file_size = 2M apc.write_lock="1" apc.localcache = 1 apc.localcache.size = 512 apc.report_autofilter="0" apc.include_once_override="0" apc.coredump_unmap="0" apc.stat="0" apc.stat_ctime="0" The problem is i have my APC memory fragmented into 5 pieces at 14,5MB loaded into memory which capacity is 64M. My system memory is 640MB, used about 270MB at most. The http responses lasts about 300ms - 5s. When i switch on apc.stat="1", the responses are about 50ms - 80ms which is quite good, but i cannot understand why is apc.stat="0" so much whorse. The APC diagnostic tool shows "1 Segment(s) with 64.0 MBytes (mmap memory, pthread mutex Locks locking)" in general cache information window so i hope i am right that it's mmap setup which allows tweaking APC shm onto upper values than shows system limit in /proc/sys/kernel/shmmax (my shows 33MB).

• Is anyone using KVM in production?

  - by Andy Shellam

  I've been trying to set up a pair of servers utilising KVM on Ubuntu 9.10 to host 8 virtual machines between them and ended up with various issues from the VMs freezing, to not powering on. I had one virtual server set up and running and was setting up a second, when any operation involving OpenSSL would cause the VM to lock up in a weird way - all network traffic would cease, it wouldn't process logins on the console, but it wasn't taking any CPU time off the host. The first virtual server was identical and worked perfectly. Another VM I tried to setup had installed Ubuntu fine then refused to reboot, throwing kernel exceptions to do with XFS. I've now installed Citrix XenServer 5.5 on both hosts, and am now setting up my third VM with absolutely no issues. I also had the same experience when I tried VMware, but I preferred Xen as it appears to give more features on the free license. My question is am I just unlucky with KVM, or is KVM as unstable as it appears? Are you using, or planning on using, KVM in production, and how successful have you been?

• Cygwin - Repo with Separate Git/Working Dir Doesn't Work

  - by Kyle Lacy

  Since I've switched to OS X and Vim, I've found it easiest to manage all of my 'dotfiles' (all of my configuration files and miscellaneous scripts) with Git. Having already set up my dotfiles in a repo following this tutorial, I figured it would also be easy enough to migrate all of my settings into my Cygwin setup on my Windows partition. Already having the repo setup on Github, I simply clone'd the repo, and moved all of the files over to my home directory, making it a mirror of my OS X home directory. Unfortunately, I cannot seem to use the actual repo any further within Cygwin. The problem is that I cannot use my dotfiles repo with git within Cygwin. The setup is unique from most normal git repos, in that the working directory and the git directory are in different locations. Specifically, the working directory is $HOME (/Users/kyle on OS X, /home/kyle in Cygwin), and the git repo is $HOME/.dotfiles.git. So, if I wanted to get the status of the repo, for example, I would type the following command (which I alias to reduce typing, of course): git --work-tree=$HOME --git-dir=$HOME/.dotfiles.git status -uno While this works fine on OS X, this refuses to work within Cygwin. Regardless of whether or not I use my alias, or whether or not I substitute $HOME by hand, I get the following git error: fatal: Not a git repository: /home/Kyle/dotfiles/.git/modules/.build/git I don't understand where this error comes from, but the path /home/Kyle/dotfiles was the original location of the git repo when I initially cloned it. Additionally, it's important to note that the repo relies heavily on submodules. If specifics are necessary, the repo in question can be found on GitHub. The commands I ran to setup the repo in Cygwin can also be found within the Readme file.

• Understanding Linux SCSI queue depths

  - by Troels Arvin

  I'm experimenting with the effects of different SCSI queue depth values on a Dell server running CentOS Linux 5.4 (x86_64). The server has two QLogic QLE2560 FC HBAs connected via multipathing to a storage system. The storage system has allocated two LUNs to the server, each connected through four paths in an active-active-active-active round-robin configuration. All in all, the two LUNs exist as eight /dev/sdX devices, represented by two devices in /dev/mpath. I currently adjust the queue depth values in /etc/modprobe.conf and check the result (after rebooting) by looking in the seventh column of /proc/scsi/sg/devices. Two questions related to that: Is there a way to adjust queue depths without rebooting or unloading the qla2xxx kernel module? E.g., can I echo a new queue depth value into some /proc or /sys-like file to update the queue depth? If I set the queue depth to 128, is that 128 in total for all devices handled by the qla2xxx module?, or 128 for each HBA? (256 in total), or 128 for each of the eight /dev/sdX devices (1024 in toal)?, or 128 for each of the two /dev/mpath/... devices (256 in total)? This is important for me to know so that my server doesn't flood the storage system, affecting other servers connected to it.

• X11 performance problem after upgrading from Centos3 to Centos5 with an ATI Rage XL

  After upgrading a computer from Centos3 to Centos5 an application that does a lot of scrolling took a very high performance hit. top tells me that X is using a lot of CPU and that was not happening before.

• ClearOS - how to create a site to site VPN between two ClearOS boxes?

  - by Scott Szretter

  I plan on setting up some ClearOS boxes at several sites, and would like to set up site-to-site VPN between the remote sites and a main site (all running ClearOS enterprise 5.2sp1 / latest version). I have found references for how to set up ClearOS to VPN in to devices such as cisco for IPSEC, and others with PPTP. But for these methods it did not mention how you might configure 2 ClearOS boxes to talk to each other ipsec or pptp. I also saw documentation on installing OpenVPN and using the OpenVPN client software to VPN in to the ClearOS box. I will probably use this for individual users to VPN in, but I have some small sites ( 1 to 10 users) that will have their own ClearOS box and need to create a site to site VPN link back to the main site's OpenVPN box. Is this possible, can you point me to docs, or other info or basically, how? A couple updates: I did find a thread that asks the same basic question, where the user has a vpn set up between the two clearos machines (after installing ipsec vpn modules), just not transporting traffic between the LANS - and the very last post claims you have to edit some files (/etc/ipsec.conf) and set leftnexthop rightnexthop values to %direct. After that, it's supposed to work. Could it be that simple? I also posted to clear foundation, and they pointed me to some documentation for setting up ipsec unmanaged vpn. This looks pretty good, but, I will most likely need to figure out how to handle a dynamic dns type setup at least on one end. Also, what does it mean by multi-wan? Finally, what happens when a vpn connection goes down exactly - someone has to reboot the box or ?

• SSI includes not working on Debian with Apache

  I'm trying to get SSI to work on Debian running Apache, however the .shtml files are not being parsed. From a PHP file with phpinfo() I can see that the following show up in the loaded modules section: mod_mime_xattr mod_mime mod_mime_magic In /etc/apache2/mods-enabled/mime.conf I have (among other things): AddType text/html .shtml AddOutputFilter INCLUDES .shtml In /etc/apache2/sites-enabled/domain.com.conf (for the virtual host in question) I have: <Directory /home/username/public_html> Options +Includes allow from all AllowOverride All </Directory> and for good measure, I added the following as well: <Directory /> Options +Includes </directory> In the user's .htaccess file, I tried adding: Options +Includes AddType text/html shtml AddHandler server-parsed shtml Nothing seems to work. How can I even debug this?

• URL Rewriting on GoDaddy Virtual Server

  - by Aristotle

  I migrated a Kohana2 application from a shared-hosting environment over to a virtual dedicated server. After this migration, I can't seem to get my .htaccess file working again. I apologize up front, but over the years I have never experienced so much frustration with anything else as I do with the dreaded .htaccess file. Presently I have my project installed immediately within a directory in my public folder: /var/html/www/info.php (general information about server) /var/html/www/logo.jpg (some flat file) /var/html/www/somesite.com/[kohana site exists here] So my .htaccess file is within that directory, and has the following contents: # Turn on URL rewriting RewriteEngine On # Installation directory RewriteBase /somesite.com/ # Protect application and system files from being viewed # This is only necessary when these files are inside the webserver document root RewriteRule ^(application|modules|system) - [R=404,L] # Allow any files or directories that exist to be displayed directly RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d # Rewrite all other URLs to index.php/URL RewriteRule .* index.php?kohana_uri=$0 [PT,QSA,L] # Alternativly, if the rewrite rule above does not work try this instead: #RewriteRule .* index.php?kohana_uri=$0 [PT,QSA,L] This doesn't work. The initial controller is loaded, since index.php is called up implicitly when nothing else is in the url. But if I try to load up some other non-default controller, the site fails. If I place the index.php back within the url, the call to other controllers works just fine. I'm really at my wits end, and would appreciate some direction here.
