HP-UX Secure Shell Getting Started Guide

# cat /opt/ssh/etc/ssh_host_dsa_key.pub ssh
root@RemoteMachine ’cat >> /opt/ssh/etc/ssh_known_hosts’
Or
# cat /opt/ssh/etc/ssh_host_rsa_key.pub ssh
root@RemoteMachine ’cat >> /opt/ssh/etc/ssh_known_hosts’
For SSH-1:
# cat /opt/ssh/etc/ssh_host_key.pub ssh root@RemoteMachine
’cat >> /opt/ssh/etc/ssh_known_hosts’
You can view the /opt/ssh/etc/ssh_known_hosts file on the server and verify that
the public host key of the client is added to this file.
6. In the server system, add the fully qualified host name of the client at the beginning of the
key in the /opt/ssh/etc/ssh_known_hosts file, as shown in the following example:
client.abc.com ssh-dss ssh-dss AAAAB3NzaC1kc3MAAACBAKCJJv/D2

bK6Hobu2qI= root@client
In this example, client.abc.com is the fully qualified host name of the client that is
appended to the key in the /opt/ssh/etc/ssh_known_hosts file.
7. To connect to the remote server, run the following command from the client system:
# ssh <server_name>
Where:
<server_name> specifies the name of the remote system to which you want to connect.
The HP-UX Secure Shell client connects to the HP-UX Secure Shell server.
Using User-Specific Configuration
To configure host-based authentication for non-superusers using user-specific configuration,
follow the steps specified in “Using Systemwide Configuration” (page 43). However, the host
configuration files that you need to update are user-specific files, not the systemwide files.
Table 4-4 describes the systemwide configuration files and the corresponding user-specific
configuration files.
Table 4-4 Host Configuration Files
Systemwide FilesUser-Specific Files
/opt/ssh/etc/shosts.equiv$HOME/.shosts
/etc/hosts.equiv$HOME/.rhosts
/opt/ssh/etc/ssh_known_hosts$HOME/.ssh/knownhosts
Configuring Host-Based Authentication for Superusers
To configure host-based authentication for superusers, follow the steps described in “Using
Systemwide Configuration” (page 43). For the superuser, HP-UX Secure Shell uses the information
specified in the $HOME/.shosts and $HOME/.rhosts files. It does not use the information
specified in the systemwide configuration files /opt/ssh/etc/shosts.equiv or /etc/
hosts.equiv.
