I have to be able to use rsh, beause I am setting up a Linux cluster and the cluster software needs rsh (this is why I am not using ssh)

I have 2 computers : cserver , node01 . On both I have created the ~\.rhosts and the \etc\hosts.equiv files.
However it just seems not to work. If I do this from cserver:

[username@cserver username]$ rsh node01 pwd
node01: Connection refused - is the error I get

If I do the same command from node01:

[username@node01 username]$ rsh cserver pwd
poll: protocol failure in circuit setup - is the error I get

I have just installed RH 9 on both computers and as far as I know they are setup completely the same. I know that they are connected in the network because I am able to ping from one to the other . I just dont know why my rsh does not work.

Please give me an advise
Thank you for your time and help

rsh is a xinetd service. did you change the configuration files on the machine? they are disabled by default

check
/etc/services

and depending on your distro,
/etc/inted.conf
or
/etc/xinted.d/<rsh>or<rlogin>? ;)


But really, you should rather be using
ssh anyway.

is it redhat?

if so use this

chkconfig rsh on

and you should definately use ssh instead

Thanks guys. I could not make rsh work, but I followed your advise to switching to ssh. I turns out that the software I am using (LAM) can also be configured to use ssh. Thanks

you may try to runt these commands

chkconfig rlogin on
chkconfig xinetd on
