During lunch I grabbed your code and it compiled cleanly. accept() didn't work (on Linux) because intlen wasn't initalized to sizeof(struct inaddr_in).
The way you have keepsake temporarily hold onto the head of the list and iterate using descr_list is odd. So I changed descr_list to be descr_head. It always is the head of the list (Then no need wasting struct space on a list pointer in each and every descr). Then iterate with:
Removed some dead code and it worked.
I think somehow you're getting descr_list to be NULL and trying to reference descr_list->next. Not sure, might look later at the original code but it was easier this way for me.

I looked again at fixing your implimentation and couldn't. I can't wrap my head around where descr_list may be at any given moment since it's a global and changed in a function (initalize_descr) called from main().... here's snipplets of my changes

Hi,
I would like to write a program to receive the GPS data and then send the data via network to other program.
All of the program is not write yet(include host and sender)
All of the server OS is unix or linux
Could you mind to give me some idea to do this?
Thanks so much!

in a single main() function,so need signal handling. Use Posix Message Queue IPC mechanism , can ignore the priority and other linked list message,to implement the scenario:
