Lamboot
 

I have setup my work cluster with password less rsh. This works fine when I was rsh or rlogin to anynode; however, when I try to execture lamboot, it prompts me for passwords.

I have given this command:
lamboot -ssi boot-rsh-agent rsh hosts.lam
-and this one-
lamboot -ssi boot-rsh-agent rlogin hosts.lam
-and this one-
lamboot -ssi boot-rsh-agent "rsh" hosts.lam

but they all get prompted for a password.

Any ideas?

i do not know about RSH but u can setup SSH easily.

$ssh-keygen -t dsa -f ~/.ssh/mykey
$cd ~/.ssh
$mv mykey identity
$cp mykey.pub authorized_keys

at this point u can login urself without password.

check
$ssh YOURIPADDRESS.

if it works u can use SSH for CLUSTERING.
but you should export LAMRSH variable.
$export LAMRSH=ssh

so u can login ??

My only concern with passwordless SSH is: what about multiusers? Does every user have to issue the commands to create the SSH Key? Also, if they do, is there an easy way to create them when a new user is being created? Also, does every user have to execute the same commands on every node?

If that's the case, it might become very tedious very quickly.

my only idea is just acreate a single .ssh directory and put it in all the users directory.
so that every user can ssh without password.
or else u can just create an script whenever the user is added just kept the .ssh
dir to my home folder through root permission.
