Hello, I have 3 computers that I want to be able to ssh and rsh to each other with out needing to use their uses password. I'm running slackware 9.0 on the first 2 computer and slackware 9.1 on the 3rd, I can ssh to them normally with out problems when i do rsh i get this:

arnie@t800:~$ rsh t1000 -n echo $SHELL
t1000.skynet: Connection refused

I want them to be able to talk with out passwords so i can use lam 7.0 on them (www.lam-mpi.org)

Here are the files i have on each machine

my /etc/hosts.equiv:

localhost
t800.skynet arnie
t1000.skynet rpatrick
tx.skynet kloken

my /etc/host:

127.0.0.1 localhost
192.168.0.201 t800.skynet t800
192.168.0.202 t1000.skynet t1000
192.168.0.203 tx.skynet tx

my /home/[username]/.rhosts:

t800.skynet user=arnie
t1000.skynet user=rpatrick
tx.skynet user=kloken


I think I'm meant to add something to the /etc/passwd file but im not sure what. Any help will be appreciated.
thanks

1) Perform login without a password promt from "remotehost" to "thishost".

- open a shell
- ssh remotehost -l user
- cd .ssh
- ls
-> if id_dsa, id_rsa etc exists,
skip the next two steps!
- ssh-keygen -t rsa
- ssh-keygen -t dsa
- scp *.pub user@thishost:~/
- exit
- cat id_rsa.pub >> .ssh/authorized_keys
- cat id_dsa.pub >> .ssh/authorized_keys
- rm id_rsa.pub id_dsa.pub

You should now be able to connect from "remotehost" to "thishost"
without a password promt.

thanks, It works for ssh but not rsh. I still get the conenction refused.

rsh is insecure (really !!!), but ....

rsh solution:

add host A to /etc/hosts.equiv on host B and vice versa
now you should be able to rsh from A to B and vice versa without password
( user XXX on host A can log on as user XXX on host B )

yea, and so is allowing ssh without a password!! lol

i'll swap 1 ssh session with required keys for 100 rsh sessions any day (security wise )

*G*

Thanks, im not really worried about security though :P
