Cisco IR829 Integrated Services Router
Chapter 5 Guest Operating System (Guest OS) Installation and Configuration
Configuring NAT
Note Ensure that the PermitEmptyPasswords parameter is set to no.
PermitRootLogin yes
PasswordAuthentication yes
PermitEmptyPasswords no
Step 3 Restart SSHD:
[GOS]# /etc/init.d/sshd stop
Stopping sshd: [ OK ]
[GOS]# /etc/init.d/sshd start
Starting sshd: [ OK ]
[GOS]#
Step 4 From the IOS command line, enter the following:
IR800#iox host exec enablessh IR800-GOS-1
ssh enabled successfully.
You now have remote SSH access to Guest OS.
Configuring NAT
The following example configuration uses NAT for Guest OS network connectivity, where:
• 9.1.1.0 is the externally reachable subnet.
• 9.1.1.131 is the external IP address made available for Guest OS access.
• 192.168.1.0 is the private subnet created for Guest OS to Cisco IOS connectivity. This is not directly
reachable outside the IR829.
• The IP address acquired by Guest OS through IOS local DHCP pool is 192.168.1.2. This address
can be obtained using show iox host list details command from IOS.
