Changing Web Server Port Numbers

User Guide for CiscoWorks Common Services

The restrictions that apply to the specified port number are:
• Port numbers less than 1025 are not allowed except 80 (HTTP) and
443 (HTTPS). Also port 80 is not allowed for HTTPS port and port 443 is not
allowed for HTTP port.
•
The specified port should not be used by any other service or daemon. The
utility checks for active listening ports, and if any conflict is found the utility
rejects the specified port.
There is no reliable way to determine whether any other service or application
is using a specified port. If the service or application is running and actively
listening on a port, it can be easily detected.
However, if the service is currently stopped, there is no way that the utility
can determine what port it uses. This is because on Windows there is no
common port registry equivalent to /etc/services as in UNIX.
•
The port number must be a numeric value in the range 1026 – 65000. Values
outside this range, and non-numeric values are not allowed.
When you run the utility with the appropriate options, it displays messages on the
actions it is performing.
It lists out all the files that are being updated. Before updating, the utility backs
up all the affected files in CSCOpx\conf\backup, and creates, appropriate, unique,
sub-directories.
It also creates a new file called
index.txt.
This text file contains information
about the changed port, a list of all the files that are backed up, and their actual
location in the CiscoWorks directory.
