As for root's login -you have to add the following lines to /etc/securetty
pts/0
pts/1
pts/2
and so on.. add at least 30 so the last line will be pts/30
however it's very unsecure.You can use ssh instead...

I would suggest that you implement SSH as suggested in the earlier post. Its free and you don't have to pay for it :-)

The '/etc/securetty' way around not being able to rlogin as root is to put 'rsh' in it.

remove the '+' from the .rhosts entiries. Make sure .rhosts has 600 permissions (-rw-------), and is owned by root.

ensure that the 'rlogin' service is started.

After checking all of that, show us the error messages in the log files (usually /var/log/mssages or /var/log/secure).

Is /root/ your root user's home directory?

grep root /etc/passwd Are you getting 6th field as /root?

If okie then,

hostB
/root/.rhosts
hostA root

hostA
/root/.rhosts
hostB root

Else

Put .rhosts file on / as /.rhosts with the same settings in the above

It will allow the rlogin from hostB <--> hostA on root user only.

Change the permission of them to 600 so that others can not access it.

Check is your rlogind (eamon) running?

You will get some log informations on /var/log/messages.
