I keep getting the response 130; obviously an error. Where can i find a
list of error codes on linux?
Unfortunately there is no such thing. Exit code 0 for success, non-0
for failure. Some programs have documented exit codes other than 0
and 1.
Here is some information from the BASH man.page:
EXIT STATUS
For the shell's purposes, a command which exits with a zero exit
status
has succeeded. An exit status of zero indicates success. A
non-zero
exit status indicates failure. When a command terminates on a
fatal
signal N, bash uses the value of 128+N as the exit status.
This would indicate that your program terminated on a fatal signal 2,
since 128+2 = 130.
From "man 7 signal":
SIGINT 2 Term Interrupt from keyboard
Interrupt from keyboard is what normally happens when you type <ctrl> C.
If this isn't what happened, and you wrote the program yourself, maybe
it doesn't have a proper exit() statement. Or somebody else wrote it
without a proper exit() statement.

I am trying out Kubuntu to see if I want to use it. Everything is
working well. The only problem (so far) is I cannot ssh into my other
computer from kubuntu. THe command hangs and I have to Ctrl-c to get
out; thus the error code 130. I can ssh from the other computer into
kubuntu; so I assume everything is configured correctly there, and the
problem is in the config in kubuntu. THe ssh_config files are exactly
the same in both. I was hoping the error code would give a clue as to
the problem.

OpenSSH_4.2p1 Debian-7ubuntu3, OpenSSL 0.9.8a 11 Oct 2005

debug1: Connecting to main [192.168.1.50] port 22.
In the past with other distros if ssh cannot connect I usually get some
error message like connection refused, or cannot locate.
Thanks for you clear explanation. I read that part of the bash manual
but the 128 + 2 did not register with me.
