hi,

do u mean ports of services, e.g. telnet ftp, http, e.g? if so, please refer to /etc/services for the standard ports.

regards.

[Joseph Loo]

however, if u mean ports your server are listening or established:

# netstat -an|grep -i listen

# netstat -an|grep -i estab

regards.

netstat -an
lsof -i tcp
lsof -i udp

Hi,
HAve a look at:

/etc/services
/etc/protocols
# netstat -a
# rpcinfo
# man services
# man protocols

That should help.

Hi,

Check this file : /etc/services
This is a file for all registered port in HP-UX, the one with mark means the port is blocked and the one with unmark means the port is used as per normal.

More details, check the man page :

# man services

Hope this information can help you.

Cheers,
AW

Hi,

netstat -an
If the ports are shown in names you can find them in /etc/services.

Here is the link for lsof
http://hpux.connect.org.uk/hppd/hpux/Sysadmin/lsof-4.76/
lsof -i tcp
lsof -i udp

netstat can help you to find it out.


Following link gives a list of ports on any unix machines;
http://www.iana.org/assignments/port-numbers

This holds good for HP-UX as well. So look at this link to find all port numbers and relavant services.

Hi,

You have the answers to your request now, I would just add /etc/services is a valid source only if the Sysadm has kept it up to date...
So dont trust only this file but double check with netstat and lsof...
And if you add new services, dont forget to update /etc/services.


All the best
Victor

ports listed in /etc/services does not mean that they are being used. Ports NOT listed in /etc/services does not mean they are NOT being used.

It depends on what ports the various listener are looking for. /etc/services is a nice way for us humans to put name to number.

If I understand your question. I would suggest that you look at port scanner like nmap

Shiv, you can use the following ..
1) /etc/services
2) netstat -na
3) lsof
