I'm ssh'ing from my linux machine to a Solaris network with the following command: ssh -lusername remotemachine I can logon just fine and run any unix commands fine (i.e. ls, cd, etc). However, I cannot execute any programs I know are on the remote unix machine. For example, there is a program on the remote unix machine called foo that I know exists (and I can see it if I do and ls and the file permissions are rwxrwxrwx), however when I type foo on the command line to execute it, I get "Command not found." Am I missing a flag on the ssh command or a configuration file somewhere? Thanks for your help

How about if you change to where "foo" is and run ./foo Lawrence

What Lawrence is saying is that for security reasons the current directory is not included in your path. If it was some intruder my place a malicious executable with the same name as a system executable in a directory other than what is in your path and you could be tricked in to running it. Don't change your path. If you need to execute something outside of the normal directories ./executable .
