rcp 'permission denied'

I've followed suggestions as mentioned in this thread


& I can now rcp a file to one of our servers, however there is another one which I still cannot contact, I just get the error 'permission denied'.

I've checked & doublechecked the contents of /.rhosts & /etc/hosts on both systems and they seem ok.

Any suggestions as to what could be causing this?

I'm on Sco 5, using my root login to rcp.

I got this from the man page. You must have read and exe permission on all directories that are involved on both boxes. If you don't, your rcp will fail.

man rcp

" The rcp command copies files, directory subtrees, or a combination of files and directory subtrees from one or more systems to another. In many respects, it is similar to the cp command (see cp(1))."

" To use rcp, you must have read access to files being copied, and read and search (execute) permission on all directories in the directory path. Note that there are special requirements for third-party transfers which are described in the Third-Party Transfers section below. "

All the permissions are set as drwxrwxrwx or -rwxrwxrwx on both machines. Ones for development & the other is a off-site test system (I'm looking into releasing software over an ISDN link instead of what happens now, where an engineer goes in with a tape)

I have an idea it might be to do with the receiving machine (skipton) not allowing the sending one (gozo) to excecute the command, but the file I believe controls this (/etc/hosts.equiv) has an entry as

gozo root

There is another server (malta) that I can rcp to, which I've compared to skipton & can't see any differences. Would it help you for me to post all the relevant /.rhosts, /etc/hosts & /etc/hosts.equiv?

You might see if the r* commands are disabled on that box.

I am assuming you have root on this box...

Sorry, I'm not a system adminstrator, how can I tell if they've been disabled? I can see /usr/bin/rcp on each server, is that enough?

By the way, the files when copied onto malta end up with permissions of ' -rwx------ root sys' if that's any help

You would have to ask your SA.

Read the Man page for rcp. Here is another excerpt.

" The rcp routine does not prompt for passwords. The current local user name or any user name specified via ruser must exist on rhost and allow remote command execution via remsh(1) and rcmd(3N). remshd(1M) must be executable on the remote host."

Read the Man page for rcmd and remshd as well.

It may be that your user doesn't have the same privileges on that other box, like you do on malta.

Sorry I can't be more help. rcp is usually reserved for Root user. At least it is with my company. We implement a Secure form of FTP for my users/DBAs to transfer files.

Thanks for the advice, we don't have a dedicated unix expert/SA - I'll just have to keep muddling through.

I'll post the answer when (if?) I find out what the problem was.

Great site by the way, I've learnt loads from reading other threads.
