Troubleshooting using strace

Hi,

Today I faced some issues on bind9, as I was unable to start the bind service using service command. I just went through the logs /var/log/syslog. But didn't get any information about this issue. Finally I used strace which was very usefull to troubleshoot.


strace -f /usr/sbin/named -u bind

It will trace the whole process . Then I was able to find permission denied error for /usr/lib/ssl/openssl.cnf. I fixed the permission issue and then I was able to start the bind.

Cheers
