Hi All, I'm wondering if you know any pros and cons of running OTRS on Linux vs running it on Windows? Apart from obvious differences that come from OS, are there any benefits for the application whan it's run on Linux (eg. is it more stable, better tested etc)? I'm just about to choose the platform so any info would be useful. Thanks a lot -- Robert

Hi Robert, We have started running OTRS on Windows Server 2008 R2. We are currently investing in how to migrate to Linux because we have unstable performance, more need for windows updates (and necessary repoobts) and the system log for OTRS which is only enabled for linux. Also we want to save the costs to purchase the Windows license. So if you are familiar with Linux I would recommend to go for Linux. Also the large amount of installations seems to be on Linux which is the impression I got when browsing many forum entries in order to solve issues and questions. I am also new to OTRS and therefore am looking for further inputs by the community. Regards, Jan On Sat, Jan 29, 2011 at 12:07 PM, Robert Poreba < poreba.robert@googlemail.com> wrote:

Thank you Jan,
That's very helpful.
I'm installing OTRS on 2 systems today, Windows Server 2008 R2 and SLES11.
We'll see how it goes.
I'm familiar with linux, however my colleagues are not. They would prefer it
to be on Windows in case I leave the company or break my leg ;)
I'm going to suggest them that if worst comes to worst, they can always
migrate it to Windows..
Anybody else had any issues with OTRS on Windows (or Linux)?

I've run OTRS 2.x and now 3.x on Windows 2003 as well as 2008 for a couple of years with relatively few problems, certainly nothing like what Jan experienced. Our biggest problem has been growth of the database in MSSQL 2005.

We have been using 2.4.x on Windows with no issues for about a year now.
I tested with both Windows and linux at the time. The linux system
was noticeably faster when dealing with system parameters, but I
couldn't get the active directory authentication working correctly under
linux at the time (even with same config information from working
windows box), so ended up on Windows since AD authentication was a very
important requirement.

Hi All,
Thanks a lot for all your comments and information.
Based on that, I think we will go for linux in that case, although I will
also need to find a way to set up single signon with it.
Thanks again,

Let me know how you get it working. Maybe I'll take another stab at it
on linux as well. We run mostly windows anyway, so it hasn't been an
issue. I only noticed the speed difference when editing the system
configuration.

Hi All, Just in case it's helpful to anybody. This is how I implemented SSO witn NTLM authentication on SLES. I know there is a howto about it on wiki but it was missing few bits in my case. 1) Installed Apache2::AuthenNTLM module by running: # perl -e shell -MCPAN cpan[1]> install Apache2::AuthenNTLM 2) Edited /etc/apache2/httpd.conf and added KeepAlive On 3) Edited /otrs Location in /etc/apache2/conf.d/otrs.conf and added PerlAuthenHandler Apache2::AuthenNTLM AuthType ntlm,basic AuthName Basic require valid-user PerlAddVar ntdomain "DOMAIN dc1 dc2" PerlSetVar defaultdomain DOMAIN PerlSetVar ntlmdebug 0 where: DOMAIN - name of our NT domain (just the first bit of the name, before the first dot) dc1, dc2 - names of our domain controllers (just the hostname, without domain bit). Make sure you can ping those names 4) Edited Config.pm file and added $Self->{'AuthModule'} = 'Kernel::System::Auth::HTTPBasicAuth'; $Self->{'AuthModule::HTTPBasicAuth::Replace'} = 'domain\\'; where domain - name of our domain again 5) Added to /etc/hosts IP_ADDR DOMAIN DOMAIN.CO.UK where IP_ADDR is the IP address of my primary domain controller 6) And the final bit (that took me few hours to work out btw) is to addmod_perlto APACHE_MODULES in /etc/sysconfig/apache2 7) Restart apache and otrs Once this is all done, I'm logged in automatically when going to OTRS login page. The only thing is that it only works when: - I'm using Internet Explorer and the site is in 'Local Intranet' zone - I'm on the local company network, ie. it doesn't work over vpn so it's not perfect. -- Kind Regards, Robert

I'm wondering if you know any pros and cons of running OTRS on Linux vs running it on Windows?
I was wondering about this as well. In this (or was it the german OTRS list? I forgot!) I'm getting the impression that quite a few people are actually using OTRS on Windows. Some seem to use IIS, some are using Apache. With varying success. Given that OTRS (unlike some other trouble ticket systems like the one we're using) is *TRULY* a browser-agnostic solutions, I fail to see why anybody would use a Windows Server unless one has to. You can use it from a windows system with IE, Firefox, Chrome, just pick a damn browser :) OK, one might have profound experience with Windows Server systems, but profound knowledge of running these mixtures of open source and closed source software? Ususally I'd go the path of least resistance and go for the homogenous system! Stuff like (mod_)perl + Apache have been tested and USED in production for ages (on Unix and Linux), while I have the feeling that the userbase of "mix-n-match" setups like IIS and (whatever-name)Perl or Apache on Windows + (whatever-name)Perl is smaller -- and thus the resulting systems are somewhat less well tested. Maybe the OTRS makers can shed some light on this by e.g. statistics from their bugtracker? (although this sampling would only represent people having PROBLEMS, not people NOT having problems with their setup).
Apart from obvious differences that come from OS, are there any benefits for the application whan it's run on Linux (eg. is it more stable, better tested etc)?
Personally, I'm running 3.0.5 (and 2.4.x prior to this) on Ubuntu and it has been rock solid. No reboots, no hangs, no performance issues; it just worked. I'm not using an OTRS package, I installed from source. Upgrades (of both OTRS and the OS) just worked. OK, I've been doing stuff like this for 16 years now, but you wouldn't let just anybody setup your ticket system, would you? -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebrandt@charite.de | http://www.charite.de
