Not a very detailed description of anything.

You tried to add what to _what_? A ".rhosts"
file in a user's home directory is good for
only that user, not for all users.

I don't use it, but you might look at:

man hosts.equiv

I mean I added + + to ~edp_user/.hosts , my intended result is all user can rcp file to this server via the user ~edp_user , but it is not work , I tried other server is ok , only this serer is not ok .

Thanks

Do you mean ".hosts" or ".rhosts"?

Still true.

Still true.

Huh?

As usual, showing actual commands with their
actual output can be more helpful than vague
descriptions or interpretations.

the reply ,

man hosts.equiv do not show how to setup all user can do rcp without adding all user to .rhosts.

the command I use is rcp file edp_usr@remoteserver:/tmp

Thanks

Really? Normally that's _exactly_ what it
shows.

This is called trust relationships which can expose server security...

edit file /etc/hosts.equiv

hp01 user1
+ user2

This will allow user1 from hp01 remote machine and user2 from all remote machines.

Now chmod 600 /etc/hosts.equiv to prevent other users from modifying it.

Wouldn't it be faster and easier to try it
than it is to ask? Which method would be
more reliable?

man hosts.equiv

What does it say there?
