RE: Permit root login for telnet..



 Shekhar,

	I don't remember how to turn on telnet.

	That said, *ANY* comuter that can access the netowrk this server
is on can be used to sniff a clear-text password sent through telnet.  I
understand that in your specific case, this may be OK, but are you
absolutely sure that *every* employee accessing one of these computers
can be trusted not to set up a sniffer?  And any future employees?
There is no point in having a server if no one's computer can access it.

plays harp for food,
