Need help in debugging daemons with GDB

[Shiladitya (শিলাদিত্য)]

 There is a simple way to get around that. Create a shell script by the same
 name as the daemon that you intend to debug and replace the daemon by
 the script. Let us say you daemon is called "shriek". Rename it to
 "shriek_real"  and name your shell script as "shriek". shriek will
 look like this :

 "
 #! /bin/sh
 /usr/bin/xterm -e gdb -x {full_path}/gdb_script
 "
 and your gdb_script will look like this:
 "
 file {full_path}/shriek_real
 b addr
 r
 "
 You will be able to get control of the daemon right at its entry point
 when you restart the daemon "script".
 Hope that helps
