TOP Tips – TCP/IP
TOP – Not just a Pretty Face for NonStop!
by: Matt Riesz
TOP is a great GUI for just about everything you need to do on your NonStop system. One of the most helpful features is the ability to easily look at data communications information, especially as it pertains to CLIM IP, or “CIP”.
Let’s suppose that you want to see who is using TCP/IP on your NonStop system, and what programs are listening for incoming connections on a particular IP address, and which IP ports they’re using. Seems simple, right? But even if you do this on a frequent basis and can recall all of the SCF commands involved, it can be a tedious and time-consuming task:
First, find all of your CLIMs:
TACL> SCF 1-> assume process $ZZCIP 2-> status clim * CIP Status CLIM Name Config State Trace NCLIM000 Yes STARTED OFF NCLIM001 Yes STARTED OFF SCLIM000 Yes STARTED OFF SCLIM001 Yes STARTED OFF SCLIM002 Yes STARTED OFF
Note that the command returns both IP CLIMs and Storage CLIMs. So, pick an IP CLIM and look at the detailed status. There’s a LOT of information:
3-> status clim NCLIM000, detail
CIP Detailed Status CLIM \PAPEX.$ZZCIP.NCLIM000
Mode...................... IP

CLIM HW Config Status..... Configured

NCLIM000.eth1 -- NCLIM000.eth1 ZB018
NCLIM000.eth2 -- NCLIM000.eth2 ZB02D
Now you have the information needed to find out which IP addresses are associated with which interface on that CLIM. But who is using those addresses?
Next, find all of the CIPSAM processes – These are called “Providers” in CIP, and are the processes that your program accesses when it wants a connection. Each provider is associated with one or more CLIMs, and there may be more than one provider for a given CLIM:
4-> status provider * CIP Status PROVIDER Name Status TPStatus Trace ZB018 STARTED Started OFF ZB01C STARTED Started OFF ZB02D STARTED Started OFF ZB02E STARTED Started OFF ZB03C STARTED Started OFF ZB03D STARTED Started OFF ZTC0 STARTED Stopped OFF ZTC1 STARTED Stopped OFF ZTCP0 STARTED Started OFF ZTCP1 STARTED Started OFF
Well that wasn’t too hard. Next, find out which provider is associated with the IP address you’re interested in:
5-> status provider zb018,detail

You might need to look at all the providers to find the one you’re looking for. But great, now we know which CLIM, interface and IP address is driven by this provider. Now, enter another command to find all of the listeners and established sessions through the provider for that interface:

There may be a LOT of listeners and sessions, appearing in no particular order in the SCF output and, as you can see, it’s not very easy to read. So next you copy the output from your screen (or log it to a file and copy that) into a spreadsheet, separate it into useful columns of information, and sort it to find what you’re looking for.
That all will probably take you about 15 minutes if you know the commands by heart or maybe an hour or more if, like me, you have to read through the SCF manuals looking for them.
A great alternative is to use TOP:
Sign on to TOP and select your system. The system’s components appear in a familiar, Windows-Explorer-style interface
Navigate to “Comms”, “TCP/IP”, “IP CIP”
TOP now shows the available IP CLIMs. Select one, and click on its “Interfaces”. You now see the CLIM’s interface information, including which providers are using them and which IP addresses are being served:
Now click on “Providers”. Top shows information on all the providers:
Next, right-click on a provider and select “Sockets” from the pull-down menu. TOP provides information for all of the current active sockets for that provider:
Sort it however you want by clicking on a column heading. For example, by Foreign IP Address, to see who has an active session:
Total time to do this with TOP: about 1 minute, and you don’t need to know any command syntax. Information from the TOP display can also be easily copied and pasted into your favorite spreadsheet. It’s EASY!
