protocol error, string closed connection

Cause

rlogin(1) fails on SunOS machine.

Action

1. Check the permissions on in.rlogind on the machine you are trying to connect to. The permissions should look like this:

-rwxr-xr-x  1 root     staff       16384 Jan 20  1994 /usr/etc/in.rlogind

2. Check the login line in the /etc/inetd.conf file. It should look like the following:

login	stream	tcp	nowait	root	/usr/etc/in.rlogind	in.rlogind

3. Check /etc/passwd to see if an invalid login shell has been substituted in the entry for the login id.
