You have the following options:
1) You could get cray to compile you a version of their telnetd with out the
%$# KLUDGELINEMODE support! The %$# KLUDGELINEMODE support is the
real problem. It is a real KLUDGE!!!! It breaks the older
telnet clients.
If they cannot not figure out how to make you a version with out the
%$# KLUDGELINEMODE support then send me a note and I can send you a 5
line mod that does this.
You may see a little more cpu overhead, I saw at most .025% increase
in a YMP/864, but not enough to worry about. You may swap more but
no more then those users that are using rlogin. Some user that
are coming overy a busy network will see echoing delays, if this
is a problem I would get those user to use the newer version telnet the
does the real telnet LINE MODE.
2) Always use rlogin.
3) Install a version of telnet the does the real telnet LINE MODE on
all your non cray hosts.
4) Always turn on the "extproc" stty option on the cray. The turns off telnet
line mod processing completely off both the %$# KLUDGELINEMODE and the
real telnet LINE MODE.
It's a cray problem!
