Saving the Changes to Flash

Once you have completed the setup and test, change the file system back to
read-only and save the changes to flash. (Note that on the system shown below,
NIS was running. NIS was used for both the login authentication of “kerrym” and
to obtain the permissions for the serial port.)

root@km3210 /var/tmp$ exit
exit
sysadmin@km3210 /var/tmp$ exit

Listening for an NIS domain server: quasar.lci.net
system SAVE complete
sysadmin>

Final Testing

Reboot the SCS to verify that the test procedures above operate. If not, return to
the appropriate section above and verify your setup. From the command-line
shell of the sysadmin login, command a reboot:

sysadmin>reboot

Once the console server reboots, attempt to access the ports from your Telnet
client workstation or machine. Access from a Unix workstation is similar to that
shown below:

kerrym@quasar $ Telnet 192.168.202.11
