 Posted: Sun Apr 14, 2013 8:02 pm Post subject: Eggdrop crashes on telnet connection |
 |
|
I can't find anything about this type of problem online, so I figured I'd have a go here. I'm running an Ubuntu server (12.04.2 - GNU/Linux 3.2.0-40-generic x86_64).
Everything is up to date.
I compiled Eggdrop 1.6.21 (I also tried 1.8-dev with same results) with MegaHAL 2.7 (I also tried 3.5 with same results).
It compiles successfully, and starts up successfully, I can /msg botname hello successfully, and I can /msg botname pass password successfully.
BUT every time I try to connect via telnet, eggdrop crashes with the following:

I figured I'd disable telnet and try connecting via DCC and CTCP and I can't (in fact I can't connect via DCC or CTCP with telnet enabled either, even after changing NAT hostname values).
Any clues as to what might be happening? |

Tell us more informations like how you start your eggdrop, if you added a listen port for the eggdrop and if you tryed starting the eggdrop without megahal and used /ctcp botnick chat

I start it from the install directory using ./eggdrop wilbot.conf (after the user file has been made).
I did add a listen port, the default 3333.
I've tried it without loading the megahal module (and once without even compiling it), same buffer overflow.
When using /ctcp to chat, I get an Accept/Ignore prompt. When I select accept I get:
| Quote: | DCC Chat session
-
Client: Wilbot (IP ADDRESS HERE)
Time: Sun Apr 14 22:24:18 2013
-
Acknowledging chat request...
DCC Chat connection established
-
DCC session closed |
and eggdrop crashes again.
So it appears as long as I have telnet enabled, I can reach it via CTCP but not DCC, but it still crashes like it does with telnet. |

Have you tryed installing the same version of eggdrop and megahal version on another unix machine? It could be a problem with you version of server.
I always had craches on my machine when loading tcl scripts that had problems.
