Hello.

Which .rhosts file are you talking about? These files are per-user. The generic configuration file is hosts.equiv (see the man page).

Did you check if rcp works at all - i.e., even if you specify exact host/username pair and test with that?

Once you set up .rhosts for one user, you can just copy it, provide you only have machines listed and not with the optional username.

(Basically users who don't want to set up their own .rhosts files don't deserve to use rcp. :-)

Thx replies ,

Now my case is the server can rcp files to each other but need to add all users to .rhost file .

How to make it can rcp file but no need to update .rhost again ?

Thanks.

The .rhost file allows the usage of wildcards '+', however a lot of deamons ignore this out of security reasons.

In fact the whole rcp thing is one huge security risk!

How about using scp instead?

If you really insist on using this, you may add the configuration to the /etc/skel. That means that all new created users will receive the config from this template.

Another solution would be to create a shell script that may be invoked by cron to assemble the config by scanning all available users from "getent passwd".
