Software Management
A.
Software Management manipulates the Windows registry to automatically manage remote
authentication during the rcp transfers on Windows. The following registry parameters are
important for rcp service on Windows:
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\crmrsh\Parameters\DEBUG
Dictates the amount of debug information written in the Windows event log.
(Default = 0, Maximum = 0xff)
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\crmrsh\Parameters\rhosts
Contains the list of authenticated hosts that can run remote commands on this machine. This list
is automatically managed by Software Management.
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\crmrsh\Parameters\rusers
Contains the list of authenticated remote users that can run remote commands on this machine.
This list is automatically managed by Software Management.
• HHKEY_LOCAL_MACHINE\SYSTEMCurrentControlSet\Services\crmrsh\Parameters\NoRuserC
heck
If set to 1, the remote user authentication is skipped or, in other words, any remote user from
authenticated hosts can run commands on this machine. (Default = 0)
• HKEY_LOCAL_MACHINE\SYSTEMCurrentControlSet\Services\crmrsh\Parameters\NoRhostCh
eck
If set to 1, the remote host authentication is skipped or, in other words, commands can be run
on this machine from any remote machine.
(Default = 0)
Q.
How do I upgrade Network Analysis Module (NAM) using Software Management?
A.
To upgrade NAM using Software Management:
• Ensure that the passwords for NAM’s application and maintenance modes are the same.
This is because Software Management takes the password information from Inventory.
However, Inventory requires the application mode password to manage the device, and Software
Management requires the maintenance mode password to upgrade the device. Therefore, the
passwords for NAM’s application and maintenance modes should be the same.
• For a NAM card present in a Catalyst 6000 device running CatOS, ensure that you set auto
logout to a value that is high enough to allow the copying of the new image.
This is because a NAM image is usually very large (nearly 65 MB), and it may take between 1
to 2 hours to copy this image during Software Management upgrade. We recommend that you
set the auto logout to 0 to ensure that there is no auto logout while the image is being copied.
To set the auto logout value, use the CLI command, set logout 0.
For a NAM card present in a Catalyst 6000 device running IOS, ensure that you set exec timeout
to a value that is high enough to allow the copying of the new image. We recommend that you
set the exec timeout value to 0 (
exec-timeout 0 0) on all the vty lines.
• Ensure that the htdocs directory under CSCOpx has enough space to stage the NAM image.
During the NAM upgrade, Software Management first copies the NAM image from the
NMSROOT/CSCOpx/files/sw_images directory, to the NMSROOT/CSCOpx/htdocs/swimtemp
directory and then copies the NAM image to the NAM card, using HTTP.
• Ensure that NAM is added with the correct Local User (root) and its password.
• Ensure that NAM is added with the correct SNMP read/write community strings.
