[comp.sys.apollo] Rlogin locks up

danny@idacom.uucp (Danny Wilson) (12/23/89)

After installing SR10.1 we are experiencing strange problems
with rlogin locking up.

This problem only happens if you rlogin 'two deep', which means in our
case:

	apollo1 --rlogin->  sun1  --rlogin-> sun2

If you do this, after the rlogin to 'sun2', no characters are
echoed on the original apollo.  Keystrokes are properly passed
to 'sun2' and commands can be executed if you terminate the command
with a LINEFEED instead of a CR.  

When you press LF, the command is echoed 'in toto' and the output
from the command is visible.

This problem does not happen with:


	sun0 --rlogin->  sun1  --rlogin-> sun2
or,
	apollo0 --rlogin->  apollo1  --rlogin-> apollo2

Anyone know what is is going on??

PH (Possible Hint) #1
When you rlogin to 'sun1' first a '!' character is printed;
a second later, the login message from the Sun is printed.
This does not happen in any other circumstance

PH#2
After connected to sun2, 'stty sane', 'reset' or 'tset' commands
do not fix the problem any.

    It sounds like your pseudo-ttys ("/dev/?typ?") are messed up.
I've seen some strange problems caused by messed up device files.
Try deleting all the pseudo-tty files and then using "/etc/crpty"
to recreate a fresh batch.
    I had one case where a sour OS install messed up lots of the
stuff in /dev. None of the user processes knew what their "TTY"
was. (IE you'd do a "ps agux" and ALL the processes had a "?"
in their "TTY" field.) I had to delete everything out of /dev
and use /etc/mkdev to recreate it all.
