gdb:

1. find the pid of the unresponsive ssh process using "ps auxww | grep
ssh"

2. attach to it using gdb "gdb /path/to/ssh" then "attach PID" (using
the pid you found in step (1).

3. Capture a backtrace "where". 

The others depend on which platform you are on. Generally it is a
matter of running "strace -p PID" (or similar for the others). ktrace
is a little different, because you need to start the trace (using
ktrace) then dump the output using kdump later. Check the manpage for
the tool for your system.
