Can I ask for some advice? We've just set up two Slink machines in a graduate student lab. They have ethernet connections; there is no firewall. Some of the students want to do all their work in a regular way on these machines and those students have user accounts. But a number just want to be able to telnet or ssh to another machine quickly and check email. Is there a safe way to set up a `guest' user-account with a publicly known password? Jim
