IP port customization? (telnet)

» close window

The Question is:

 
I am using the TCPIP> facility (OpenVMS 7.1/Alpha) and trying to set the port
 for telnet to something other than 23 (for security purposes). The command
 ENABLE SERVICE TELNET /PORT=nn only works for port 23, so there must be a
 config file somewhere to ent
er a list of permissible ports. Any suggestions?
 
 

The Answer is :

 
  For security, the OpenVMS Wizard finds it preferable to set up OpenVMS
  host security, break-in evasion, passwords, and auditing and alarms
  correctly, rather than attempting to maintain security through obscurity.
  Appropriate IP firewall(s) -- for monitoring and controlling both inbound
  and outbound IP traffic -- are also of obvious interest here.
 
  Various TCP/IP tools and utilities are built to assume the use of the
  particular (assigned) IP ports.  Some of topics 1316, 2628, 3903 and
  3778 might also be of interest here.
