Installing the Linux Client System

The Linux client systems can be installed locally by using the

distribution media, or remotely using the Installation Server for UNIX.

See http://www.openview.com/products/omniback/specifications/ for

details about supported Linux platform versions.

NOTE OmniBack II uses the default port number 5555. Therefore, this

particular port number should not be used by another program. This is

possible on some versions of Linux (such as 6.4). If the port number 5555

is already in use, you should make it available for OmniBack II or you

can change this value to an unused port number. See Appendix B ,

“Changing the Default Port Number,” on page B-11.

environment, you have to perform local installation from the distribution

media, that is the OmniBack II CD-ROM for UNIX. See “Local Client

Installation on the non-HP-UX Platforms” on page 87 for instructions.

At this point you should have Installation Server for UNIX already

installed on your system. See “Installing the OmniBack II Cell Manager

(CM) and Installation Servers (IS)” on page 16.

You remotely install a Linux client system by distributing the OmniBack

II components from the Installation Server for UNIX to the Linux

system, using the OmniBack II graphical user interface. For the

step-by-step procedure for distributing the software, refer to

“Distributing the OmniBack II Software to Clients” on page 34. Before

that, note which components you select when distributing the OmniBack

II software to the Linux system:

Disk Agent Select the Disk Agent component to be able to back up filesystem data

with OmniBack II.

OmniBack II command-line interface on the client system.

backup device connected.

For information on other OmniBack II components, refer to “OmniBack

II Components” on page 38.

As soon as the client components have been installed, the target system

automatically becomes a member of the OmniBack II cell.

system, ensure that root account has rights to access the system either

by using exec or shell services. To achieve this, do the following:

1. Edit the /etc/xinetd.conf. Find the definitions for exec and shell

services and add the following line to the definition of these two

services:

server_args = -h

For example:

service shell

{

socket_type = stream

wait = no

user = root

server = /usr/sbin/in.rshd

server_args = -L -h

}

service exec

socket_type = stream

protocol = tcp

wait = no

user = root

server = /usr/sbin/in.rexecd

server_args = -h

}

NOTE Some Linux distributions have these services configured in separate files

in /etc/xinetd.d directory. In this case locate the appropriate file

(/etc/xinetd.d/rexec and /etc/xinetd.d/rsh) and modify it as

described above.

2. Kill inetd process with the HUP signal:

kill -HUP $(ps ax|grep inet|grep -v grep|cut -c1-7)

3. Create a ~root/.rhosts file with the entry:

That will allow administration access from the Installation Server.

After you have installed OmniBack II, you can remove the entry from

~root/.rhosts file, -h flag from the /etc/inet.conf (/etc/inetd.conf for

RedHat 6.1) file and repeat the kill command from the step 2.

For more information, see rexecd(8), rexec(3), rshd(8), rsh(1) or pam(8)

manpages. If this fails, refer to “Local Client Installation on the

non-HP-UX Platforms” on page 87 for instructions.
