check_by_ssh does not initiate a full login shell when executing commands. In fact, it is a simple but intelligent wrapper for 'ssh [EMAIL PROTECTED] somecommand' so as such, the ssh command on the remote host is going to see only the environment variables available for a non-login process and those that ssh specifically sets. 'man ssh' and search for 'ENVIRONMENT'. That section of the man page will detail the limited number of environment variables that ssh will set on it's own and how to add others via $HOME/.ssh/environment. check_by_ssh doesn't modify or limit the remote environment in any way. -- Marc ------------------------------------------------------------------------- Using Tomcat but need to do more?
