Admin Mod Issues On Linux

haven · November 2002

<div class="IPBDescription">Admin Mod Issues on linux</div> Hi, not sure if anyone can help but here goes:

I run two linux natural selection servers. I used to run cstrike and so I'm used to running admin mod on both machines.
With the release of NS 1.03 I thought I would install admin mod for NS since it is supposed to work.

Using a default install of AdminMod (no tweaks at all other than editing users.ini) I get the following error:

./hlds_run: line 83: 24971 Segmentation fault (core dumped) $HL $*
Add "-debug" to the ./hlds_run command line to generate a debug.log to help with
solving this problem

I have had this same error on both servers and both servers have been independantly installed i.e. they are not mirrors of each others files.

I ran debug and got the output shown below:

I have emailed this to sdk@valvesoftware.com although I don't expect a response.

If anyone could offer some suggestions on what might be causing this ? Once I disable Admin Mod the servers are fine again. Having heard reports of others successfully running Admin Mod on their linux boxes I puzzled.

If you need any further information then please request it - I'll be happy to post it up.

Many thanks in advance

Well I installed adminMod as soon as I installed ns v1. had no problems whatsoever. Now this might simple be an ommision in your post. But you mentioned all you did was edit the users.ini.

Now according to your core-dump, adminmod and metamod libs where loaded, So I would assume its a simple setting error. Did you go through and edit the adminmod.cfg? I assume you did. What I'm wondering is if you edited the plugins.ini file. As this seems more like its trying to load a plugin for cs or tfc and its seg faulting the server.

ie;
#2 0x436f428e in __dynamic_cast (from=0x4374ec74 <CTimer type_info function>,
to=0x4338e514 <CBaseDoor type_info function>, require_public=1,
address=0x8114b28, sub=0x43373150 <CBaseEntity type_info function>,
subptr=0x8114b28) from /usr/lib/libstdc++-libc6.1-1.so.2

Pherhaps your could paste your adminmod.cfg & plugins.ini files into a post and let me look them over.

Recompile your admin_amx.so

I've given instructions how in this post:

WOW, I've never heard of the plugin lib causes any type of problems, And I've been useing adminmod for years now. But it wouldent truly shock me if that is the problem. It most certainly seens tobe in the plugin system anyways. Ither a bad plugin,(actually quite common) or a plugin that shouldent be loaded and is causeing conflicts with ns and seg faulting the server. Or as you seem to have, a problem with the plugin lib and the rh7.3 libc6 libs. But personally I would update the RH7.3 libs to current libs before I'd bother recompiling the plugin lib.

I had a quick check of the plugins.ini file - both the TFC and CS plugins were commented out by default so I left it at that and didn't edit any further. I've since deleted the lines entirely and re-launched the server with the same error

My plugins.ini file now reads as follows:

addons/adminmod/scripts/plugin_message.amx
addons/adminmod/scripts/plugin_retribution.amx
addons/adminmod/scripts/plugin_fun.amx
-------------------------------------------------

As for the adminmod.cfg - I left it as default to test the server so it was not edited before launch. I've since gone through and made some changes to see if it made any difference - it didn't unfortunately.

If you spot any plugins that you think should be omitted in the above list then feel free to point them out - personally I don't see why any of them would cause problems, but I'm not as familiar with admin mod as I would like to be and their exact functions are not completely clear.

The redhat libs are completely up to date - in order to get NS working I do however, have to create a symlink i.e.
ln -s libstdc++-libc6.2-2.so.3 libstdc++-libc6.1-1.so.2

It seems NS doesn't recognise the newer lib without this link <img src='http://www.unknownworlds.com/forums/html/emoticons/sad.gif' border='0' valign='absmiddle' alt='sad.gif'>

I think this is my next course of action - I'll have a go and let you know if it works or not. Thanks for all the responses.

I was running Mandrake and could not get AM to work. Switched to RH7.3 and all problems went away...

Let me get this straight, you would change the librarys that the system is dependant on before you recompiled a simple little library? OKAY...

Besides that, the binary seems to work fine with ALL my CS servers, it just AdminMod wouldn't work at all until i recompiled that one library...

And just so you know, the libc6 RH7.3 has are a version above the one required by adminmod.

None the less, it's really not hard, you download the cvs, type make in a directoy, and copy a file over to the proper location.

What its taboo to keep your system libs upto date? And yes, if I was havening a problem, and I hadent already for some reason updated to the newest released libs. I would use the problem as an excuse to update them. Then I would look into recompiling the admin_mod libs.

Now i only recently changed over to redhat, as for years I've always ran slackware. But A few of my friends who work for RH kept harping on me to try ver8 out. So i changed over. That being said, I'm not sure if pre RH8.0 has the up2date command access. But I'm sure it has something similar. And it makes keeping your system up-to-date so easy, that they're is no reason why you shouldent be keeping all your system and its libs up-to-date.

All the same I find it strange that you would think upgradeing your OS is such a bad idea. Regardless of the problems your havening. You update hlds when they release a new version don't you? And I assume you would also update adminod and metamod libs as new bug and optimized versions come out? So why wouldent you also keep your system libs (that are most important libs on your os) upto date as well? First step I take whenever I have a problem is updateing my OS, to ensure its not a problem with outdated, or a bug in the system libs.

And if the AM lib your haveing a problem with was compiled useing the newer libc6 libs, It would stand to reason it might conflict with an older lib that has bugs in it the newer libc6 doesn't. But I wasn't sayining its BAD to recompile the AM plugin lib. I just said personally, I would update my system libs to the newest before I starting recompiling AM libs.

And to fix the problem with NS starting and not finding the proper link to the libc6 libs. Rather then creating a link to patch it to the older lib system. I just updated the libstdc libs.

IE>
up2date compat-libstdc++

And then NS ran fine, as it created the proper links and libs NS was looking for. See how easy updateing your system makes life.

DrGiggles · November 2002

Either way, for me, it required that I recompiled the admin_amx.so lib. Not the whole adminmod_MM_i386.so, just the amx interperator. The compile was very easy and took about a minute, and suddenly it worked.

I don't understand why everyone feels the need to discredit the fact that a recompile of a simple library would fix anyones problems. Adminmod is an open source project, the source is free, it's not hard to attain, and if recompiling a small part of it makes it work on some systems without having to dink around with the system too much, right on.

btw, up2date has been around for a while, and it's run automatically on my system in question via a cron job.

haven · November 2002

Well, I've just spent two hours "playing" with adminmod and metamod to no avail unfortunately. All my servers still core dump as soon as someone joins while Admin Mod is running. I've followed DrGiggles suggestions and I've followed a few thoughts of my own, none of which worked for me.

I think I've spent enough time on this one so I'll be going without adminmod on my servers for the forseeable future.

Heres hoping that an easy and workable installation appears at some point in the future.

Thanks for all the advice. If anyone does come up with a foolproof (and idiot proof for the benefit of yours truly) installation solution to the admin mod problems then please post them up as I'm sure lots of people could benefit.

The conclusion I have come to is that adminmod is simply not very compatible with natural selection - after all it runs on all my servers fine with other mods - just not this one <img src='http://www.unknownworlds.com/forums/html/emoticons/sad.gif' border='0' valign='absmiddle' alt='sad.gif'>

HtNickoli · November 2002

I never used it myself, but I understand clanmod is almost just as good as adminmod. maybe give that a try.

DrGiggles · November 2002

I used clanmod for about a week before adminmod would work for me, it was pretty nice. Menus were a little hard to get used to, but now I'm using menus in adminmod because I liked them so much <img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' valign='absmiddle' alt='smile.gif'>

Thanks for the advice - just installed clanmod and it works like a charm - I see what you mean about the menus, they are very handy.
