Thanks, Sven >From the Xsession(5) man page: "Administrators unfamiliar with the Bourne shell will likely find the Xsession.options(5) configuration file easier to deal with than Xsession itself." No doubt true, but I fancy myself to be a reasonably adept, all be it slow, reader of Bash (making frequent use of 'man bash'.) I likely will resurface in a few days/weeks with further questions. And you are right about /etc/init.d/ssh . Its name is a misnomer. It should be called /etc/init.d/sshd but maybe not... Maybe the maintainer of the ssh init script could introduce a comment about ssh-agent into the script giving the information that you have just given here. I think this might be done without wider ramifications to the overall installed code of Debian, as would surely be entailed by changing the name of the script. Just a few lines of comment where almost everyone who is curious this will look. Especially if the misnomer is preserved. -- Paul E Condon pecon...@mesanetworks.net -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
