Special Procedures
Note Be sure you enter the redirect operator twice, with no space (>>). If you enter it only once
(>), you will overwrite the existing file rather than appending to it. If you make a mistake, enter the
command cp /.rhosts.bak /.rhosts to recover the original file.
Step 6 On the remote node, examine the file /usr/etc/hosts to verify that there is an entry for
distribution-node in it. You can use the grep command for this (enter the name of the
distribution node in place of distribution-node):
bash# grep distribution-node /usr/etc/hosts
Step 7 If there is no entry for distribution-node, create one:
bash# cp /usr/etc/hosts /usr/etc/hosts.bak
bash# echo ” Primary_IP_address distribution-node ” >> /usr/etc/hosts
Enter the IP address of the distribution node in place of Primary_IP_address, and the name
of the distribution node in place of distribution-node. (You can use the vi editor in place of
the echo command. See the LightStream 2020 NP O/S Reference Manual for information
about the vi editor.)
Note Be sure you enter the redirect operator twice, with no space (>>). If you enter it only once
(>), you will overwrite the existing file rather than appending to it. If you make a mistake, enter the
command cp /usr/etc/hosts.bak /usr/etc/hosts to recover the original file.
Step 8 Log out of the remote node and repeat Step 1.
If the test fails again, contact Cisco Customer Support at 1-800-553-NETS (6387) or
1-800-553-2447.

Remote Nodes”).
Special Procedure E, Backing Up the Distribution Diskettes
To protect the software distribution diskettes, you can back them up before proceeding with the
upgrade.
Requirements for the Procedure
In this procedure, you are assumed to have access to a PC running DOS 5.0 or later and supporting
at least one 1.44 MB floppy disk drive. You are also assumed to have a supply of at least 15 blank,
DOS-formatted 1.44 MB diskettes.
Note With the /v option, the diskcopy command verifies that the copy is correct. If you wish to use
the diskcomp command redundantly to verify that the copy is correct, refer to your DOS
documentation for that command.
