strace

I was recently stumped by an odd incoming network connection hang problem on a linux server. This is a writeup of how I troubleshot the issue and eventually fixed it.

Programming a UNIX® system can be fun as well as educational. With the UNIX strace tool and GDB, the GNU Project Debugger, you can really dig deep into the functionality of your system and learn a lot about the various programs that comprise it. Using both tools in concert can be a rewarding experience as you look under the hood of your UNIX machine.
