Re: Telnet escape character and error display

The usual reason for such delays is a DNS
problem, where address-to-name look-ups fail.

> Error: Can't open display:

Look at your shell start-up script(s)
(.login, .profile, and/or whatever) to see
which command is actually failing here.
(This could also be DNS-related, but it's
hard to say much with no actual information.)

Re: Telnet escape character and error display

the "Can't open display" message coms from the unix-hosts wich tries to open a (X-)terminal window on your workstations xserver.
wich could mean
- either your workstation isn't running an x-server
- or the unix-host cannot find this (name resolution issue ).
- or there may be an entry in the host-file and the entry of this workstation do not match.
- Or your local xserver does not accept these connections (try "xhosts +" to temporarily allow any host to open a window).
- as in the previous post a command in the loginscript prevents is faulty or cannot execute correctly.

Or the DISPLAY variable is set to some
nonsense, or not set at all, or any number of
other things. "Can't open display:" invites
the obvious question, "Which display?"
