Re: Two network cards

Network guy told me the IP address is outside the hospital. It is at
the System Office. Nothing in the local DHCP servers.

Try a NSLOOKUP 'xxx.xxx.xxx.xxx'
where that is the cifs IP address. You may get something like:

= gdl164.dekko-1.

Which is my PC name. If you name your PC's meaningful or have a table of
who is using which PC that may help.
Here, GDL164 may have their 5250 session equal to GDL164S1 and an object
lock on that, config status, etc, may help determine who that is.

I did a traceroute from my pc to the cifs IP address. Just a guess at
this point, but the destination and one hop may be at our System
Office, since it appears to go through our gateway. I have asked the
network guy if he can identify.

I need to look at the links you sent in more detail. Thanks for the
links. Google is my friend. Just need to get time.

VERY NICE. Thank you Dr.!

I currently have three connections. Two are to local port telnet.
The third is to local port cifs.

What is cifs? Are multiple connections coming through that path? I
was wondering if this is a shared connection of some sort.

Add to Rob's response, NETSTAT *CNN but use F15 to subset to the local
internet address of 172.x.x.x (Be specific). That way you'll only see
connections to that address. Refresh periodically for a while. If you
see nothing (except the "*" Listeners) then try shutting it down.

The comm trace idea is better if you think there might be just a random
connection now and then.

Some time back, a second network card was added to our i. One card is
on 172.x.x.x and the other is on 10.x.x.x.

Most activity is now off the i, compared to what was there last

October.

Network guy wants to shut down the 172.x.x.x address.

Is there a way to determine if that address is still used by somebody?
Even if not at a particular moment?

The other option is to shut down the 172.x.x.x and wait for the calls
to come in.
