Hi,

can any one give an example for configuring .rhosts file so that
i can allow some trusted computers in my LAN to access my ubuntu 8.04
machine via telnet,ssh without having to enter password

BTW there is no /etc/hosts.equiv file in my machine, so will i have to
create it ...????

Easy enough, FQDN space user name per line or ip_addy user name.


$ cat ~/.rhosts
wb.home.invalid bittwister

Be sure to chmod 600 ~/.rhosts

It is a bad idea to use telnet. Too many systems have had passwords stolen.
That the remote computers (or local computers) are trusted is irrelevant.
You also have to trust every inch of lan as well.
On ssh, use the authorized-key mechanism. Place the contents of
..ssh/id_rsa/pub into the other computer's .ssh/authorized_keys file to
allow you to log onto their system without a password. That replaces teh
notion of .rhosts or /etc/hosts.equiv

Yes, you would have to create it if instead of listening to everyone you
decided to go that route.

and rlogin.

If you use rlogin, then anyone on the remote computer can pretend to
be anyone else on your system.

In other words, the application on the remote machine says "The user is fred"
even if it really is joe. Joe can pretend to be fred.

That's why I use ssh/scp.

Many wrote about telnet.

If you want to log in using SSH, look at
