sudo and core dump

vladimir gershman — Thu, 03 Apr 2003 19:54:30 GMT

Hello,

I am using sudo to run a program that is supposed to generate a core file. However, if I use "-b" option, the core file is NOT dumped. Without "-b" I do get a message about "Segmentation fault", but I cannot find the core file. Is this a sudo issue?

Thanks,

Vlad

Does the effective id of the running process allow the process to dump core in the current directory?

check the permissions of the current directory and then try to run the sudo command once again.

I don't think this is a problem of sudo.

Hi

I agree that this is a permission fault.

As owner of tyhe directory do
touch core
chmod 777 core

Then try again.

Beware the the program started with sudo may well chdir before dumping core :)

so maybe better first do a 'su' to the user and start the process manually, maybe it gives more info about the process' whereabouts.

Enjoy, have FUN! H.Merijn

Actually, the problem was that the version I use, 1.6.6, uses setrlimit to set coredump size to 0. It is fixed by commenting out a line below in the config.h file of sudo.
#define HAVE_SETRLIMIT 1

Thank you all.
