I have a port in an HP 3000 and I want to know the application that is currently using that port. Is there any command that can show me the applications accessing a particular port?

Kevin Miller replied:

:sockinfo.net.sys

Enter ‘c’ for ‘call sockets.’ Listeners are shown in port order.

The port for telnet on our 3000 is set to a different value then 23, but it is set to 23 on our HP Unix server. When I try to telnet from the 3000 to HP-UX I get the following message: Trying... telnet: Unable to connect to remote host. If I switch the port for telnet to 23 on the 3000, it works great.

My question is: Can I run telnet on two different ports on either box so that I can maintain my non-standard port on the 3000, but still allow telnet to run between the two boxes? If not, is there another way to make this work?

Jeff Kell replied:

Just ‘telnet your.3000.name nnn’ where ‘nnn’ is your ‘nonstandard’ port.

How do I point network printer configurations to specific ports on (external) multi-port JetDirect (or equivalent) boxes?

Gilles Schipper replied:

You need to add the tcp_port_number option, in NPCONFIG, as follows:

(network_address = 128.250.232.40 tcp_port_number = 9100) # for port 1
(network_address = 128.250.232.40 tcp_port_number = 9101) # for port 2
(network_address = 128.250.232.40 tcp_port_number = 9102) # for port 3

(Please note that everything on each line after and including the “#” represents a comment.)

My HP 3000 is set up for full access to the Internet. The telnet connection works fine, but I also see that VT-MGR also works. I know that inetdsec is used for restricting access for ip, http, ftp and so on. Is there something in NMMGR to restrict VT-MGR access, or do you use inetdsec for that also?

Just an option logon UDC that checks the CIVars set for the IP address and hostname of the originator.
