Getting Started Guide

12
When you install from a source system that is also an installation target, also
add the local system id_dsa.pub key to the local authorized_keys file. The
installation can fail if the installation source system is not authenticated.
To add the local system id_dsa.pub key to the local authorized_keys file,
enter the following command:
system1 # cat /.ssh/id_dsa.pub >> /.ssh/authorized_keys
13
Run the following commands on the source installation system. If your ssh
session has expired or terminated, you can also run these commands to renew
the session. These commands bring the private key into the shell environment
and make the key globally available to the root user:
system1 # exec /usr/bin/ssh-agent $SHELL
system1 # ssh-add
Identity added: //.ssh/id_dsa
This shell-specific step is valid only while the shell is active. You must execute
the procedure again if you close the shell during the session.
To verify that you can connect to a target system
1
On the source system (system1), enter the following command:
system1 # ssh -l root system2 uname -a
where system2 is the name of the target system.
2
The command should execute from the source system (system1) to the target
system (system2) without the system requesting a passphrase or password.
3
Repeat this procedure for each target system.
Enabling remsh
Remote shell functionality is enabled automatically after installing HP-UX.
Typically, the only requirement to enable remote installations is to modify the
.rhosts file. A separate .rhosts file is in the $HOME directory of each user. You
must modify this file for each user who remotely accesses the system using remsh.
Each line of the .rhosts file must contain a fully qualified domain name or IP
address for each remote system that has access to the local system. For example,
if the root user must remotely access system1 from system2, add an entry for
system2.companyname.com to the /.rhosts file on system1.
# echo "system2.companyname.com" >> $HOME/.rhosts
