Changing Web Server Port Numbers
If you change the port after installation, CiscoWorks will not launch from Start
menu (Start > Programs > Ciscoworks > Ciscoworks). You have to manually
invoke the browser, and specify the URL, with the changed port number.
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 SSL 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 ports listed in /etc/services. If
there is any conflict, it rejects the specified port.
•
The port number must be a numeric value in the range 1026 – 65000. Values
outside this range, and non-numeric values are not allowed.
•
If port 80 or 443 is specified for any of the webservers, that webserver process
is started as root. This is because ports lower than 1026 are allowed to be used
only by root in Solaris.
However, according to Apache behavior, only the main webserver process run
as root, and all the child processes run as casuser:casusers. Only the child
processes serve the external requests.
The main process which runs as root, monitors the child processes. It does not
accept any HTTP requests. Owing to this, Apache ensures that a root process
is not exposed to the external world, and thus ensures security.
•
If you do not want CiscoWorks processes to run as root, do not use the ports
80 and 443.
When you execute the utility with the appropriate options, it displays
messages on the tasks it performs.
This utility lists out all the files that are being updated. Before updating, the
utility will back up all the affected files in /opt/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.
