Segfault while linking bots

AXB · Post by **AXB** » Thu Jun 12, 2008 2:13 pm

Hello,

I need your help for a problem with my eggdrop.

I've got 2 bots linked with a botnet and it works fine on my gentoo 32 bit with ssl patch.
But now i'm trying to make this work on a new server using gentoo 64 bit, to replace the old server.

I installed tcl 8.4.18, compiled the eggdrop with the ssl patch of rootie, everything went fine.
I run the bots, add them to reconize each other, link the bots together and then a segfault occurs !

I've seen that without the ssl patch it doesn't segfault, but I really need it

The gdb output and the debug message aren't very useful for me and seems very vague :
See http://pastebin.ca/1046223 and http://pastebin.ca/1046224

Ssl patch found here

Same problem with eggdrop 1.6.18 and eggdrop 1.6.19 (with its own ssl patch of course).

Compiling on this :

Code: Select all

Linux 2.6.24-gentoo-r8-ipv4-64 #1 SMP Mon Jun 9 16:07:50 CEST 2008 x86_64 Intel(R) Core(TM)2 Duo CPU E6550 @ 2.33GHz GenuineIntel GNU/Linux

In my /etc/make.conf

Code: Select all

CHOST="x86_64-pc-linux-gnu"
CFLAGS="-march=nocona -O2 -pipe"

Perhaps I could try to compile it in 32 bits but I don't know how.
I also tried to use the latest CVS of eggdrop1.9 just in case, but I doesn't get anything in the install path (just two empty dirs "lib" and "include").

Does anyone knows how to fix this problem ?

I also get a segfault with one of my bots when it should talk on the channel, perhaps a problem with unicode or something ?

Have you attempted to compiling eggdrop from the source code? an not the os distro version of the software.

AXB · Post by **AXB** » Fri Jun 13, 2008 4:19 am

Yes of course, I downloaded the sources, patched it and compiled it.

I never use the distro's package for eggdrops, though gentoo is a source distro, because I modify the "msgrate" value from 2 to 0 in the source code of "src/mod/server.mod/server.c" (then the bot can send a lot of msg without any delay).

I also tried to load the bots without any .tcl script loaded and the result is the same.

Last thing, my openssl versions differs a little between the 2 servers, I've installed the same as the old server (0.9.8g instead of 0.9.8g-r2) to see if it comes from here, but same problem, segfault again

Well, finally gentoo rox !

I installed an eggdrop with emerge and tried : it works fine

For the little modification in the code I always do :
I extracted the tar.bz2 of eggdrop that emerge use (located in /usr/portage/distfiles/), modified the file and recreated the archive. Then I type the following command into /usr/portage/net-irc/eggdrop/ :

Code: Select all

ebuild eggdrop-1.6.18-r3.ebuild digest

Then emerge with the SSL use and all went fine.

I hope it will be useful for anyone experiencing the same problem, but still it should be patched in the official release...

You compiled eggdrop the proper way (not using apt)?

If so, and you had no joy, the equivalent to ebuild in Debian is 'dpkg --build'.

Code: Select all

man dpkg
