    NSA backdoor. World President Barrack Obama wrote Adam personally a very concerned letter about how they can't see any of our connections and urged us to get openSSL since they have so very many backdoors in that piece of software. Adam, scared of the consequences, obviously urged the team into complying.

    If former versions were statically linked, I'm not sure why 5.0 wasn't as well because it's causing everyone grief.
    Security reasons. A dynamically linked library is the responsibility of the server admin to keep updated.

    Re: Linux Dedicated Server for 5.0 Guide

    So anyone got an update on this? Currently I'm running my server through Wine on Linux.. Not the best way and especially not with the lag it sometimes causes due to not being able to multithread properly.

    EDIT:

    To clarify I meant the performance/crashing issues.

    @Metal

    libcurl3:i386 is needed too. I had a crash complaining it's missing. Maybe it was because metamod/amxmodx stuff, but it does not hurt to include it in the dependencies to install in your op post.

    Re: Linux Dedicated Server for 5.0 Guide

    On SOME Debian installations (64 bit) the i386 architecture is DISABLED (this usually happens with netinst).

    YOU NEED THIS!

    So, if you're STILL getting a libssl1.0.0 error, AND you have errors via the command previously stated, do this first!

    Code:
    sudo dpkg --add-architecture i386
    sudo apt-get update
    THEN run the command
    Code:
    sudo apt-get install libssl1.0.0:i386

    This is what needs to go on the front page of this post!

    I had added the new arch but forgotten to refresh apt, as soon as I did an apt update the package installed and svends launched correctly!

    Many thanks

    PS: I am running on Debian 8 64

    Now I am getting Segmentation Fault as soon as a client connects, I tried installing the package suggested on the previous page, but it complains about other packages.

    Probably similarly related to my crashing in this thread: http://forums.svencoop.com/showthrea...andom-crashing

    Same here. I have everything set up with a VPS running Ubuntu 14.04 x86. If it will help, here's a dump...

    Re: Linux Dedicated Server for 5.0 Guide

    Based on the errors i've seen, it looks like the Linux servers are crashing because it can't load a library. The server tries to access it, but since no function addresses have been loaded, it calls a null pointer. Since it happens when clients connect, it's related to the donor lookup code. It might be failing to load the SSL library.

    Re: Linux Dedicated Server for 5.0 Guide

    Did not the team try to set up a server on a freshly installed os before releasing it to public?
    Everyone is getting errors. Most common is Segmentation Fault.

    Re: Linux Dedicated Server for 5.0 Guide

    We tested the game on both Windows and Linux servers for several months. Some of our beta testers even ran servers. We didn't encounter these crashes. We simply couldn't test large player counts.

    All my servers are set to 8 slots and it crashes 20 or more times daily.

    Re: Linux Dedicated Server for 5.0 Guide

    Those errors appear to be happening in the same general location in memory. This could be a single bug in the engine causing crashes.

    I have no idea why the sven devs insist on using SSL to communicate donor perks, it's dumb; Especially when it's causing game breaking issues like server crashes. Natural-Selection had a system for assigning scoreboard icons for constellation, guides, devs and pro players which used regular HTTP communication just fine.

    Are you worried someone is going to man in the middle donator benefits or something? Because it's easy enough to use IDA on the server binary and give anyone you want benefits.

    Crash dumps are at SvenDS folder.

    This one is from "std::bad_alloc" crash. And adding -heapsize 512M won't let my server produce any crash dumps.

    Code:
    # mkdir /path/to/your/webroot/svendl
    # mount --bind /path/to/svencoop_adddon /path/to/your/webroot/svendl
    In server.cfg:
    Code:
    sv_downloadurl "http://your/webroot/svendl"
    To make the mount permanent:
    Code:
    # echo "/path/to/svencoop_adddon /path/to/your/webroot/svendl none bind 0 0" >> /etc/fstab
    Fastdl pitfalls on Linux:

    Make sure the case in the mapfilenames and maps/*.res files match the actual files on disk, otherwise the file is not served as Linux uses case sensitive filesystems. A resource specified as "sound/example/Hello.ogg" can't be downloaded if the actual file on disk is named "sound/example/hello.ogg". This can be a bit of a pain to correct as some maps released are a wild mix of upper and lowercase letters and often the bundled .res files don't match the actual files. This needs to be corrected manually. In the best case everything is lowercase and does not use special chars (besides - or _) or spaces in filenames. Files with spaces in their names or folders won't get served either.


    Protip for soundcache fastdl:

    Code:
    $ mkdir /path/to/svencoop_adddon/maps/soundcache
    # mount --bind /path/to/svencoop/maps/soundcache /path/to/svencoop_adddon/maps/soundcache
    To make the mount permanent:
    Code:
    # echo "/path/to/svencoop/maps/soundcache /path/to/svencoop_adddon/maps/soundcache none bind 0 0" >> /etc/fstab

    Protip for generating .res files:

    Use resguy


    Protip to fix permissions and remove empty files (empty files cause a never ending "validating/precaching resources" on connect):

    Code:
    $ find /path/to/svencoop_adddon -type d -exec chmod 755 {} +
    $ find /path/to/svencoop_adddon -type f -exec chmod 644 {} +
    $ find /path/to/svencoop_adddon -type f -size 0 -exec rm '{}' \;

    How about using symbolic link?

    # ln -s /path/to/svencoop_adddon /path/to/your/webroot/svendl

    If your webserver is not misconfigured, it should per default deny any access to that directory. You have to configure apache to 1. FollowSymlinks and 2. to allow access to /path/to/svencoop_adddon. This means you have to touch the config, if you touch the config you can just serve /path/to/svencoop_adddon or use an alias plus the allow statement. With the bind mount you don't need to touch your webserver config, it is more logical and does not involve complications like symlinked stuff outside of the document root (ugh).

    Why complicated when it can be simple?

    YOU NEED THIS!

    So, if you're STILL getting a libssl1.0.0 error, AND you have errors via the command previously stated, do this first!

    Code:
    sudo dpkg --add-architecture i386
    sudo apt-get update
    THEN run the command
    Code:
    sudo apt-get install libssl1.0.0:i386

    Re: Linux Dedicated Server for 5.0 Guide

    After a long search for a solution the problem of the map names, I found my way how to solve this. You need to add in the main configuration file (/etc/apache2/apache2.conf - Ubuntu 14.04) this:
    Code:
    CheckCaseOnly on
    CheckSpelling on
    But first make sure you enabled 'mod_spelling' module:
    Code:
    a2enmod speling
    service apache2 restart
    It makes force redirect from uppercase URL's to real filename (http://balls.com/GearsOfWar.wad --> http://balls.com/gearsofwar.wad) so all files with uppercase will be downloaded through fastdl http as well. However files with specific symbols still will be unable to download and you will see some black-pink textures and error models.
    p.s. you can enable this function not only using main config but .htaccess file and virtualhost config file as well.
