Special Procedures

Step 5 The following error message may be generated:

Permission denied.

If this message is displayed, the rsh permissions on the backup NP are incorrect.

• Log in to the backup NP as root using rsh.

bash# rsh other-np

password:

bash#

• Verify that the ﬁle “/.rhosts” contains the line “other-np root”. If this line is missing, add

it with the following command:

bash# cp /.rhosts /.rhosts.bak

bash# echo “other-np root” >>/.rhosts

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.

• Log out of the backup NP. That leaves you connected to the primary NP again. Repeat

Step 3. If the same failure occurs, call Cisco Customer Support at 1-800-553-NETS
