[comp.sys.dec] rlogin problem

srid@eatdust.uswest.COM (11/14/90)

 Hello
	Netters

	Can any knowledgeble soul tell me why does rlogin from

	DEC Ultrix 4.0 to Sun OS 4.1 ( sun4 architecture ) does not work?

	Earlier version Ultrix 3.1 or 3.2 this was working.


	Gopal Sridhara srid@uswest.com
	PS : This was noticed on dec station 3100 ( RISC). The problem
	I am facing is typical to Sun 4 SunOS 4.1. Other combination
	works fine.

I don't know, why rlogin/rsh doesn't work, but here is a Workaround for csh,
that works for me.

Just put the command into the background, and get it to foreground.

	rsh machine & fg %rsh

Limitations: The fg command will only work, if no other rsh is active in
		the jobs list.

May be, someone knows, why this works and will find the bug. Thinking about
the difference to a simple rsh-command, it must be a signal-handling or
filedescriptor (select ?) problem.

	I reported this to DEC several months ago, and they have verified
that a problem exists.

	Wow, that is so WEIRD!  I tried:

		rlogin sun &
		[2] 4358
		[2]  + Stopped (tty output) rlogin sun
		fg

and it works!
