Verify Network Configuration
If you have made changes to your network configuration using netconfig, you should
shutdown the Tempus Cntp and re-boot it. There are two ways to do this:
1. Cycle power to the Tempus Cntp.
2. Issue the shutdown with re-boot command at the shell prompt:
Tempus Cntp-> shutdown –r now
If you are using the RS-232 serial I/O port to communicate with the Tempus Cntp,
you will be able to see the kernel generated boot messages when the unit re-boots. You
should note the line
Configuring eth0 as 192.168.1.245...
if you have set up a static IP address, or this line
Attempting to configure eth0 by contacting a DHCP server...
if you are using DHCP. It appears near the end of the kernel generated boot messages.
If you are using DHCP and are not using the RS-232 serial I/O port, you will have to
check the DHCP configuration information maintained by your DHCP server to determine the expected IP address and log in to the Tempus Cntp using telnet or ssh
to verify successful DHCP configuration. Refer to the subsequent topics in this section
Using Telnet and Using SSH, for details on logging in to the Tempus Cntp that way. Once
you have logged in, you may perform the following checks.
If you are not using DHCP, the IP address shown should match the static IP address
which you entered during the netconfig procedure. If so, log in as “root” at the login
prompt and check the other configuration parameters using ifconfig:
Tempus Cntp-> ifconfig
eth0
