no core file

hi,
A C binary is not generating core file on segmentation fault.
ulimit -c command is giving output unlimited.Please suggest, I need to debug the program.

"Segmentation fault (core dumped)" is showing on exiting.

regards
Pawan Kumar

Have you tried the generate-core-file and the core-file commands?

Try:

ulimit -c unlimited

generate-core-file and the core-file commands are not on Linux system.

Thanks
Pawan

"serving the same" means what? Whatever, if the problem is solved, mark the thread solved (top right of this page)

is it a suid binary?
do you have write permissions in the directory the corefile will be dumped to?
check /proc/sys/kernel/core_pattern and see.
