Performing the Initial Setup
Setting Up KerberosV5 2-43
X To enable or disable accepting and sending of
Forwardable Tickets
Use the kerberosv5 forward credentials enable
command to enable the accepting and sending of forwardable
tickets. This is so you do not have to enter your password
multiple times when SSHing from the LX. This applies only to
ssh/sshd/sftp session established from the LX outbound to
another host with KerberosV5 enabled. The default is
disabled. The authentication type on the LX interface has to
be KerberosV5 to establish an SSH KerberosV5 session to the
LX’s IP address. You can check the authentication type by
looking at the show screens for the show interface
<interface_number> characteristics and show port
<port_number> characteristics commands.
Example AAA:0 >> kerberosv5 forward credentials enable
Use the no kerberosv5 forward credentials command to
disable the accepting and sending of forwardable tickets.
Example AAA:0 >> no kerberosv5 forward credentials
X To remove KerberosV5 Credentials
Use the zero kerberosv5 credentials command to remove
your KerberosV5 credentials:
Example InReach:0 > zero kerberosv5 credentials
X To set KerberosV5 Authentication on Port Async
Use the authentication kerberosv5 enable command to
set KerberosV5 authentication:
Example Async 1-1:>> authentication kerberosv5 enable
X To enable KerberosV5 Authentication on the interface
To enable server-based authentication for an IP interface, the
authentication method must be configured for the LX unit. To
enable KerberosV5 authentication on the IP interface:
Example Intf 1-1:>> authentication kerberosv5 enable
Intf 1-1:>> authentication kerberosv5 enable
