Appendix E. AIX tips 841

Adding additional IP addresses to an interface

When aliasing for Network Dispatcher, the ndcontrol cluster configure

command (or GUI) will do this for the cluster address.

1. Type

smitty tcpip.

2. Select further configuration.

3. Select Set network interfaces.

4. Select network interface selection.

5. Select Configure aliases. Add an IPV4 network alias.

6. Select the network interface in use (ex. en0).

7. Enter the new IP address and network mask.

If the wrong gateway is specified, you need to flush the routing table before it can

be reset.

Installing OpenSSH on AIX 5.1

In order to use Secure Shell (SSH) programs such as Secure FTP (SFTP), SSH

needs to be installed on all machines and the SSH daemon started. The IBM AIX

Toolbox for Linux Applications includes a port of OpenSSH 2.9.9p2. However,

OpenSSH (found at

http://www.openssh.org) is under continuous development,

and newer versions are available.

1. Download the following packages to a temporary directory (if you have not

previously done so, you will need to register with the IBM Web site):

– IBM AIX Toolbox Cryptographic Content

(

http://www6.software.ibm.com/dl/aixtbx/aixtbx-p)

• openssh-2.9.9p2-6.aix4.3.ppc.rpm

• openssh-clients-2.9.9p2-6.aix4.3.ppc.rpm

• openssh-server-2.9.9p2-6.aix4.3.ppc.rpm

• openssl-0.9.6b-2.aix4.3.ppc.rpm

– Pseudo Random Number Generator Daemon

(

ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/

prngd

/)

• prngd-0.9.23-1.aix4.3.ppc.rpm

2. AIX 5L includes the Red Hat Package Manager (RPM) utility by default. As

the root user, install the packages from the command line, in the following

sequence:

rpm -ihv openssl-0.9.6b-2.aix4.3.ppc.rpm

rpm -ihv prngd-0.9.23-1.aix4.3.ppc.rpm

The pseudo random number generator daemon starts up automatically.

rpm -ihv openssh-2.9.9p2-6.aix4.3.ppc.rpm

842 WebSphere Commerce V5.4 Handbook, Architecture and Integration Guide

rpm -ihv openssh-server-2.9.9p2-6.aix4.3.ppc.rpm

The SSH daemon starts up automatically.

rpm -ihv openssh-clients-2.9.9p2-6.aix4.3.ppc.rpm

The SSH programs are now available in /usr/bin.

Note: For increased security, you may not wish to install the openssh-server

component on all machines. For example, you can install the openssh-clients

on a machine in the DMZ to permit it to make sftp connections to the secure

network. However, that machine itself could not accept sftp connections

without the server component.
