Hello,
The system is not here yet, but i was told it's going to be RedHat Linux
Enterprise 5.1.

Ok, that's the very latest version of RHEL.  You'll need to use fairly
recent versions of the client software.  You should check the software
compatibility matrix, but I think either the 7.3.3 client or the 7.4
client would be best.

You shouldn't have to do anything special as far as installing the
client software, although you will need to make sure dependencies are
satisfied.  If you want to be able to use the GUI parts of the client,
you'll need to have quite a few X11-related libraries installed.  As
others have commented on the list, the "openmotif" package is also
required, if you go with the 7.4 client.  If these systems have a
Red Hat Network subscription, doing something like

        yum -y install openmotif

should get you openmotif plus most of the needed X libraries.

"If /etc/hosts.allow and /etc/hosts.deny is being used, you will need to
make sure that the portmap entry allows connections from your server"
Can you give me an example how this is configured ?

portmap is compiled with tcp_wrappers support.  Look in /etc/hosts.deny.
If there is nothing in there but comments and blank lines, nothing is
being denied, so you don't need to do anything.  If there's something
like

        ALL : ALL

in there, then anything that's not explicitly allowed by /etc/hosts.allow
would be denied.  If that's the case, you need to make sure that there's
an entry in /etc/hosts.allow for portmap, with your backup server's
hostname or IP address, e.g.

portmap:        10.1.1.1

"If iptables is enabled, you will need to make sure that the firewall
isn't
blocking connections from your server."
How do i query Linux system to know if iptables are enabled or not ?

        iptables -L

shows you what rules are active.  Just running

        chkconfig --list iptables

will show you if it's on.

"If SELinux is in place, you're on your own.  ;-) "
Is this part of RedHat or a different variant of Linux

It's part of most Linux distributions that use the 2.6 Linux kernel.
