using rcp commands

Juan Pena_1 — Tue, 16 Jan 2001 22:05:53 GMT

Hi all,

I have an SCO/Unix Box and HP-UX box I would like to do remote copies. What are the steps that I should take, so it can work?

Thanks Juan

You will need to either set up a .rhosts (man rhosts) file, in the users home directory, for each user that will need to use rcp or set up /etc/hosts.equiv (man hosts.equiv) If they are going to be executing rcp on the HP box going to SCO, then .rhosts or /etc/hosts.equiv will have to be defined on the SCO box.

If they are going to be executing rcp, or similar command, on the SCO box, then .rhosts or /etc/hosts.equiv will have to be set up on the HP box.

Hi:

You need to setup an /etc/hosts.equiv or $HOME/.rhosts file. See the man pages for the following:

# man 4 hosts.equiv
# man rcp

...JRF...

I created the .rhosts and even hosts.equiv
and I get the following error :

remshd: Login incorrect.

I'm on my SCO/Unix Box and I want to rerieve a file from my HP-UX Box everytime I execute a specific script on my SCO/Unix Box.

Make sure that the hostname is fully qualified in your .rhosts or hosts.equiv.

For example:

host
host.domain.org

I include hostname and the host.domain.org in my files. I had the same problem at one point and adding the fully qualified host.domain.org fixed the problem for me.

Hi,

If the SCO box is where the rcp command is issued, it is the HP box that will have to have the .rhosts file. Some things to check:

Make sure that the accounts on both boxes have the exact same login name.

Check the /etc/inetd.conf file on the hp box for the following entry: shell stream tcp nowait root /usr/lbin/remshd remshd. Make sure that there is NOT a -l option after remshd and that the line is not commented out.

Verify that the /var/adm/inetd.sec file on the HP box does not disallow the shell service from the SCO box.

Ensure that there is a shell entry in the /etc/services file on the HP box. (I don't know what the port number should be - I'm on a windows machine and can't look it up.)

Read the remshd(1m) man page.

Hope this helps,

Hi,
As Bruce mentionned, the .rhosts should be on the HP box, I just tried to rcp on an SCO a file from an HP...

Everyting works fine, only with "root" how can I make this work with a user named "juan".

one thing to check is juan's .rhosts file should have permissions of r-- --- --- i.e. chmod 400 ./.rhosts

Re: using rcp commands

Juan Pena_1 — Wed, 17 Jan 2001 14:51:22 GMT

juan's .rhosts file permissions of rw- r-- r--
so that not the problem

Re: using rcp commands

Is the ~/.rhosts file on the HP box for the user juan in that users home directory? The user juan does exist on the HP box and the SCO box?

The permissions of the ~/.rhosts file really should be READ ONLY for the owner of the file. Having that file so that it is readable by the group and world is a major security no-no.

Hi again,

If you are sure that juan's .rhosts file is correctly configured and that the permissions are correct, check the remshd entry in /etc/inetd.conf. If remshd is invoked with a -l option, only root will be allowed to use .rhosts - juan will not.

You may want to also see if the following works: replace the contents of juan's .rhosts file with two plus signs - + +. This will set up equivalency for everyone from any host. If you can log in, then it is not an inetd.conf problem. If you can't, check inetd.conf and /var/adm/inetd.sec.

Don't forget to remove the + + from .rhosts since it is a major security hole; ANYONE will be able to login to juan's account without a password.

you might try:
rcp juan@remotehost:/path /localpath

Juan, you said:"juan's .rhosts file permissions of rw- r-- r--
so that not the problem "
...Well rw- r-- r-- does not equal r-- --- ---.
I could never get the bugger to work until it was r-- --- ---. That's up to you. I'm probably not reading your response right. But, I would take the whole 10 seconds to change the mode of the file and try it. (I'm scratching my head at this time).
