ettercap0.7.4.1_debug.log debug_dump.pcap

[wacs]

This happens on Ubuntu 11.04

[wacs]

Something was written about the ec_packet.c:
"#1 0x0000000000423fcb in packet_disp_data (po=0x7ff4a59a9c30, buf=0xffffffffabfa4088

, len=48) at ec_packet.c:67"
Then was removed.
IIf there is an issue with that, how to fix it? Read a similar bug here, but same response is gone.

[Gianfranco Costamagna]

Could you please describe what were you doing when you hit the bug?

[wacs]

This happened after doing a scan for hosts:

ettercap 0.7.4.1 copyright 2001-2011 ALoR & NaGA
Ooops !! This shouldn't happen...
Segmentation Fault...
===========================================================================
To report this error follow these steps:

1) set ec_uid to 0 (so the core will be dumped)

2) execute ettercap with "-w debug_dump.pcap"

3) reproduce the critical situation

4) make a report :
"tar zcvf error.tar.gz ettercap0.7.4.1_debug.log debug_dump.pcap"

5) get the gdb backtrace :

 - "gdb ettercap core"
 - at the gdb prompt "bt"
 - at the gdb prompt "quit" and return to the shell
 - copy and paste this output.

6) mail us the output of gdb and the error.tar.gz

Core dumping... (use the 'core' file for gdb analysis)

[Gianfranco Costamagna]

Seems to be the same bug as https://bugs.launchpad.net/ubuntu/+source/ettercap/+bug/588007

could you please build the latest ettercap from http://ettercap.sourceforge.net/downloads.html and tell if the problem persists? maybe updating to a new ubuntu version could help too, your version is going to EOL very soon.

thanks

[Gianfranco Costamagna]

Hi wacs, could you please try the latest ettercap_rc from git?

This issue should be fixed there.

[Emilio A. Escobar]

Problem fixed in 0.7.4.1 and ettercap_rc branch.
