Hi,       SER cannot listen on private IP addresses, the listen address should be the public address of the interface on which SER is running. The address(es) should not be 127.* or 192.* To eliminate this problem, use either of the two simple approaches; 1. EITHER use the command line “ser –l xxx.xxx.xxx.xxx” where xxx.xxx.xxx.xxx is the public ip of the machine 2. OR, insert the line “listen= xxx.xxx.xxx.xxx” on top variable declarations sections of your ser.cfg file. This approach is a better one. Hope that helps.

Hi I'm new to Linux and SER so bear with me :) Yesterday I installed FC4 and SER (tar.gz). SER runs OK and I was able to capture some packets with Ethereal. However, this morning SER is not working. I didn't change anything in the config file. The line 'fifo=/tmp/ser_fifo' still in the config file. What should I do to make SER run again? And please explain what 'Segmentation fault' in ser -c means. Thank you.
