Question

Installing openssh 5.8

Answer

Here are instructions on how to install or upgrade to openssh 5.8

1) Download openssl and openssh from the following link

https://www14.software.ibm.com/webapp/iwm/web/preLogin.do?source=aixbp
You will have to register at the site if you do not have an account.

openssh
select 5.8
Download: OpenSSH_5.8.0.6102.tar.Z
openssl
select 9.8.X
continue
Download: openssl-0.9.8.1801.tar.Z
On your AIX system.

2) Create directory to hold openssl and openssh

# mkdir /tmp/newopenssh5.8

ftp the openssh compressed tar file to the above directory

3) Prepare the software for installation

# cd /tmp/newopenssh5.8
# gunzip *.Z
# tar -xvf OpenSSH_5.8.0.6102.tar
# tar -xvf openssl-0.9.8.1801.tar
# cd openssl-0.9.8.1801
# ls
# openssl.base openssl.license openssl.man.en_US
# mv openssl.* ..
# cd ..
# mv *.tar /tmp

4) Backup the /etc/ssh directory if it exists

NOTE: If you have an existing ssh configuration please make a copy of the /etc/ssh directory before installing the new ssh to preserve the ssh host keys. If this is a new installation there's no need to back up /etc/ssh.

# cp -pr /etc/ssh /etc/ssh-backup

5)Installation

# smitty install_all
* INPUT device / directory for software [.] (note a period)
SOFTWARE to install []
select filesets using F7
openssh.base, openssh.license, openssh.man.en_US,
openssl.base ,openssl.license, and openssl.man.en_US filesets.
Enter yes to accept license agreement

6) Verify that sshd is active

The sshd daemon should automatically start after installation has
completed.

# ps -ef|grep sshd
sshd should be running.
# lssrc -g ssh
ssh should be active.

7)Post-installation-Configurations

NOTE: After the ssh upgrade, perform the following steps only if you had an initial working ssh configuration:

# cd /etc/ssh
# mv ssh_config ssh_config.orig
# mv sshd_config sshd_config.orig
# cd /etc/ssh-backup
# cp -pr * /etc/ssh/
# cd /etc/ssh
# mv sshd_config.orig sshd_config
# mv ssh_config.orig ssh_config
# stopsrc -g ssh
# startsrc -g ssh
# lssrc -g ssh
sshd should be active
