Well, haven't been able to get a core from my server. I did
the echo '1' > ... now and also added these lines
if (prctl(PR_SET_DUMPABLE,1, 0, 0,0) == -1) {
syslog(...);
}
to my server after calling setgid and setuid.
After echoing 1 to /proc/sys/fs/suid_dumpable, I stopped
my server with systemctl and then restarted it with systemctl.
/proc/sys/kernel/core_pattern is set to this:
core.%e.%s.%t
So I'm hoping to get the core in the current working
directory of the server, but don't seem to get it there or
anywhere else. The server is able to write regular files
to that current working directory. Any more ideas?
