Hi,

I got a problem with my linux box. When I execute the soldatserver binary, I just get the word "Killed" on the console. Nothing else.

The OS is Gentoo Linux. Since it's a server, I'm using a hardened-kernel and some other security enhancements.

I tried to start the server on another gentoo box, with a typical workstation configuration, and it works.

I already added a password parameter to the line, which changes nothing. I also turned ASE_Register Off, no success.
Didn't really thought that would change anything, because on the other machine it worked without these changes, but someone mentioned it on the forums.

Can anyone help me to find out why it crashes on that machine?

Greets,
Max

"I only get "Killed" in a new line"
That doesnt make sense... please rephrase

Changed it.

Well, I type in "./soldatserver" (and I'm in the right directory) and it prints "Killed" like this:

max@server ~/soldat/ $ ./soldatserver
Killed
max@server ~/soldat/ $

This is an ordinary user, I also tried it as root - same result.

No ideas? Anyone?

Only guess is that it's either due to the server configuration not allowing Soldat to run because it's accessing something it doesn't have permission to, or a bug in the server is triggering a security check. Pretty much all you can do in that case is either: 1) Change the server configuration to be more lax on security, or 2) wait, and see if it gets fixed eventually.

My only suggestion is to check the permissions for Soldat, and any files it uses.

Hm well I checked all file permissions, tried 777 on all, but no change.

I also used the same "fresh" archive from soldat.pl as I used on the other machine (on which I had no problems getting it running).

I would appreciate the server would tell me what's wrong :P

Is this a server you own, or what? It sounds like you're running it on a server where you're not supposed to run your own programs.

Give us some background on the circumstances around this server ;)

Sure, it's a machine here at home, which is running as a file, www and some more - server.

I wanted to have it running more secure than just basic security configuration, so I use a hardened system with pax and grsecurity ('cause i found a nice guide for exactly that configuration...). And I never had that kind of problems running any programs.

I think the security addons are the reason for soldat crashing ... but is there a way to find out what exatly is the problem without try & error? I really don't want to recompile the whole kernel, mainly because the system has been running really trouble-free yet.

Maybe an option or something to make the server show me more information? Or is there a documentation telling what action can cause "Killed" as error message?

If you need more details, tell me please!

It's quite obviously the security that is causing your problems.

'Killed' is the message you receive when certain processes are sent kill signals. Usually 9 / KILL, but sometimes 15 / TERM.

The only diagnostic tool I can think off to help you is to learn how to use the tool strace. Strace will allow you to see every system call the soldat binary makes and hopefully narrow down what is causing the problem.

what user are you trying to run the soldat server as?

Thanks for the hint. Will try it, when I'm back home from vacation...

Or maybe I just give it up and wait for another version, which runs :P

The problem is most likely not the server program

What do you think, is it possible to emulate another virtual linuy system on this box to run the soldat server in?

If you are using X or some other GUI for your linux, than you can get VMWare for Linux to emulate any other operating system your heart desires.

Very good software, I use it to run my server; works like a charm.

No, I managed to run it without any GUI yet ... Will try something "console-only". Maybe it works ;-)
