Hello all,


So far I have my z/os and herc setup working well, aside from one thing and that is networking.


I am using HercGUI, Hyperion and CTCI-WIN.


I can successfully set up the Host side of things... I think, however when following instructions I can not seem to set up the z/OS side of things, or at least that's how it seems.


The end result is trying to telnet into the Herc/zOS system does not work.


Anyone able to offer any advice,hints,tips as to setting this up ?

Download this:

and read section 22 of chapter 6. It might help.

Three common things to check. Route commands in your host. And the cable
to your lan. WIFI usually doesn't permit promiscous mode (which allows
multple operating systems) And the order of adapters. Hercules always
uses the first adapter. If it is disabled it won't work.

This is what I've got in my IP profile. Maybe it'll help you.
Don't have a DEFAULTNET specified.



DEVICE LCS1 LCS E20 AUTORESTART
LINK ETH1 ETHERNET 0 LCS1
HOME
192.168.1.110 ETH1

ROUTE DEFAULT 192.168.1.254 ETH1 MTU 1500
ENDRoutes

START LCS1





And in hercules configuration file I have:
# CTC Adapters
0E20 LCS -n 192.168.1.100 192.168.1.110

0E21 LCS -n 192.168.1.100 192.168.1.110







192.168.1.100 is my PC's IP address.
192.168.1.110 is the Hercules guest IP address.


If I go into the TTTest tool, my network adapter has: PromiscuousMode? = Yes


Hope that helps.

What you could do is: 1 - make sure Hercules is shutdown.
2 - start up tttest.exe
3 - Go to Test menu, and Start Hercules, and configure Loading Image... https://www.imageupload.co.uk/images/2018/08/05/Untitled.png

4 - go to Test and Start Ping Test.


If that all works, you then know it's your z/OS configuration.




I'd also change your CTCI devices in your hercules config to LCS devices. Not sure what the advantages are, aside from LCS supports more than just TCP/IP protocols.

Ping test is fine, still cant telnet into z/OS though.


Maybe the best way to do this is to describe my network IP's and then someone can offer me a z/OS config setup that may work ?


Physical Router/Gateway: 192.168.178.1
NIC/Hercules Host: 192.168.178.40
Hercules Device: 0E20.2 LCS

z/OS Guest IP: 192.168.178.69


Should be noted that networking is not my strong point ether skill set wise, I know enough to set up a home router via DCHP but that's about it...

Likewise, my herc/zos networking setup took a while for me to get right, with networking not being my strongpoint!

All I know is my windows PC NIC has a gateway (as display in ipconfig command prompt) of 192.168.1.254


And that's exactly what I configured in z/OS IP:
ROUTE DEFAULT 192.168.1.254 ETH1 MTU 1500
And my z/OS HOME IP is also on the same 192.168.1.xxx range as my windows PC.
HOME 192.168.1.110 ETH1

Windows PC:
192.168.1.100




But looks like you're doing something different that's outside of my networking skills :) Your z/OS IP is on a different range to your 192.168.178.xxx network.


Does your NIC show as "PromiscuousMode? = Yes" in TTTest?




Whilst your waiting for someone way more knowledgeable than me (i.e. anyone!), what happens if you specify this in your hercules conf:
# CTC Adapters
0E20 LCS -n 192.168.178.40 192.168.178.69
0E21 LCS -n 192.168.178.40 192.168.178.69




And this in your z/OS IP stack profile, replacing the counterpart statements:
DEVICE LCS1 LCS E20 AUTORESTART
LINK ETH1 ETHERNET 0 LCS1
HOME
192.168.178.69 ETH1
PRIMARYINTERFACE ETH1

ROUTE 192.168.178.0 255.255.255.0 = ETH1 MTU 1500

I'm sorry if this is an obvious one, but I don't recall from the

character-mode ASCII telnet?

The problem is narrowed down in that I can ping to and from Herc via the TTTest application, however using those same settings in the actual HercGUI, Hyperion and the z/OS installation leaves me with nothing happening and no clue as to why. All I do know is that I can not ping the "live" Hercules/zOS setup, only the TTTest one successfully using the very same settings.

At one poitn you said your settings were:
Physical Router/Gateway: 192.168.178. 1
NIC/Hercules Host: 192.168.178. 40
Hercules Device: 0E20.2 LCS

z/OS Guest IP: 192.168.178. 69



then, later, you said they were:Router is on: 192.168.178. 1
Host/NIC is on: 192.168.178. 2
Herc/Guest is on: 192.168.178. 3
Subnet is: 255.255.255. 0



You can't have it both ways, so lets assume that your the second one I listed above (192.168.178.1,2&3), and NOT the one with 192.168.178.69 and 192.168.178.40





You have a few problems, one minor, one iffy and two fatal:


1) change your

LINK CTC1 CTC 1 CTCA1

to
LINK CTC1 CTC 0 CTCA1



Your GATEWAY statement and DEFAULTNET statements are supposed to be replaced by BEGINROUTES/ENDROUTES as of several releases of z/OS back (I think 1.8)


But the biggest problem is that your DEFAULTNET points to your windows box and not your router:



DEFAULTNET 192.168.178. 2 CTC1 1492 0


should be

DEFAULTNET 192.168.178. 1 CTC1 1492 0


The second big problem is that your Hercules definition is wrong I don't know what or 192.168.0.210 192.168.178.40 is, but it's not your z/OS,, so



0E20.2 CTCI 192.168.0.210 192.168.178. 40



should be



0E20.2 CTCI 192.168.178.3 192.168.178.2 (assuming .3 is your z/os, .2 is your local PC)


Also, if you are going to use the CTC, then 1492 should be 1500 in every one of them.


If you want to convert to BEGINROUTES, it should be:


BEGINROUTES
ROUTE 192.168.0.0 255.255.0.0 = CTC1 MTU 1500
ROUTE DEFAULT 192.168.178.1 CTC1 MTU 1500
ENDROUTES





I don't see how your TT64TEST could have possibly worked.


Please make the changes I listed, then post your ENTIRE hercules config and your entire TCPIP PROFILE and TCPDATA parameters.


Also, post your RESOLVER PROC and the things that your RESOLVER points to (the parms your DD"s inside the proc are pointing to).



Also you might as well list your TCPIP.HOSTS dataset and CUT/PASTE the results of your HOMETEST command under TSO, we might as well fix everything at once.

My settings were indeed the second set. Sorry that this was not more clear.. I was tired/frustrated.


I have done more testing and found that my Hercules config file is indeed apparently set up correctly re: network as I was able to install Debian Jessie successfully from a net install.


Will mess with the z/OS configuration more today and see what happens.


Thanks to all for the advice,tips etc so far.

My settings as of now are the second set as you had guessed. Sorry if that was not clear, it was late and I was tired and frustrated.


I have done more testing and now I know my settings are good on the Host side as I am able to do a net install of Debian Jessie via SSH.


So its the z/OS side that is more the likely wrong as you have suggested, I will try again today.


Thanks to all for all the help/pointers so far.

Debian only supports CTCI or QETH, it doesn't support LCS.

So this leads me to think trying QETH may be worth a go with z/OS ?
Well, that's a definite maybe. If you can't get LCS to work with z/OS, I don't see why you should succeed with QETH, which has even more things you need to do.



Have you read the copious WIN-CTCI help that Fish went to so much trouble to create?


Have you followed any of the advice given by Brian Westerman?

Yes ive gone though all the troubleshooting and tips and hints given here, all have not gotten me anywhere sadly..
Yes, but have you read the copious WIN-CTCI help that Fish went to so much trouble to create? It provides step by step hand-holding on how to configure networking on Windows.


If you want help from folk here you have to provide all of the necessary information, which means
1. the Windows network configuration, for example the output from an 'ipconfig /all' command,
2. the Hercules config,
3. the TCPIP profile.
And every time you change something and ask for help again, provide all of the information again.



A few days ago you posted:-
DEVICE CTCA1 CTC E20
LINK CTC1 CTC 1 CTCA1
which is wrong, the LINK should be:-

LINK CTC1 CTC 0 CTCA1

Or use Tom Brennan's Vista emulators Transfer ($indfile) menu to send
the file to your pc.

Or use Vista's mouse / keyboard cut / paste.

Or any other tn3270 emulator that supports $indfile

Not sure where to find Hercules Log.
Start hercules with hercules >logfile.txt
Not sure how to get the full TCPIP Profile "out of" Hercules guest OS.
Download Tom Brennan's fabulous Vista tn3270 emulator (30 day trial)
Then buy it .. it's a "whopping" $30 U.S. Best software deal in
.... history ? :)

Easy mouse driven or shift-keys cut and paste (like any other Windows program).

Great UI, online help $indfile file transport .... macros .... and on
and on ...

And Tom will respond by email if you have any problems.

No "sales commission" for me, just a very happy customer.

You could also use DASDLOAD. Hammer to crack a nut. But you could add a
sequential file (your TCPIP profile) and open it in MVS.

I updated a problem here with the cookbook approach on setting this up a few months back.


Basically, if you can log on to your TSO locally, you can enter the command 'TSO HOMETEST' and it will tell you if the z/OS side is okay.


Assuming it is, then the most common errors are that you have not set up your Hercules config adapter(s) to connect to the addresses that your z/OS instance thinks it need to use.


You need to know a few things going in:


1) The IP address of your Windows PC (the one you are actually running Hercules on)
2) The IP address of your ROUTER (both of these you get from the command prompt (IPCONFIG /ALL)
3) The IP address that you want your Hercules instance (your z/OS) to be, it cannot be the same as either of the above 2 items. It shoudl not match anything else in your local network (no other PC's) and it shoudl be a static address that you assign as static in your ROUTER (for both the PC and the HErcules instance of z/OS)

4) the device type of your connection, typincally it's defined in the Hercueles config as the LCS device (s)
5) a dummy mac address (you can use something like 02-AA-BB-CC-DD-EE) for CTCIWIN



For instance, my Windows PC local IP is 192.168.1.69 and my router is 192.168.1.64 (most people use 192.168.1.1, but I wanted to be a bit more secure). My z/OS hercules instance uses IP 192.168.1.66


My IODF has 4 CTCs defined at E20, E21, E22, E23 and I use E22 and E23 for my connection (and a backup)



So my hercules configuration entry is :



0E22-0E23 LCS -n 192.168.1.69 -m 02-AA-BB-CC-DD-EE 192.168.1.66




on z/OS my TCP/IP profile has the following (plus a lot more, but only these things matter)


E22 is my primary adapter and I am using a LCS device, you can use other types, even OSA, but I find LCS to perform the best (for me)

....

DEVICE LCSA2 LCS E22 AUTORESTART
LINK LCS2 ETHERNET 0 LCSA2


HOME
192.168.1.66 LCS2


BEGINROUTES
ROUTE 192.168.0.0 255.255.0.0 = LCS2 MTU 1492 <--MTU 1492 works well
ROUTE DEFAULT 192.168.1.64 LCS2 MTU 1492 <---router is 192.168.1.64
ENDROUTES



START LCSA2
....


As I said, there are other items before and after these, but these are the ones that matter for your purposes.


You should also make sure that your TCPDATA has the following things set:


TCPIPJOBNAME TCPIP


HOSTNAME Z23 <-- or whatever you called your host, some are ADCD, I set mine as z23, when you start up your z/OS, your COMMNDxx should have an entry like this:


COM='S EZAZSSI,P=Z23' <-- whatever you set the P= to is what you use as your host name.


DOMAINORIGIN SOMETHING.COM <-- obviously yours is something else, but whatever you use, make sure your TCPIP.HOSTS etc. is the same as this.


NSINTERADDR 192.168.1.64 <-- this is your ROUTER





Make sure you set up the RESOLVER and PORTMAP started tasks


Inside your RESOLVER task, make sure you set up:



Your IPNODES :at the GLOBALIPNODES statement and DEFAULTIPNODES statement



192.168.1.66 Z23 <-- z/OS (for me) is 192.168.1.66, and my hostname is Z23


Also, make sure that everything points to the exact same TCPDATA member of TCPPARMs, otherwise you end up with a system that you can go in one way but can't get back out.


If you set things up as I outlined, then you can connect to your z/OS from anywhere that has an internet connection (assuming you open up ports 20, 21, 23, and the SSL ports 443, 992 etc.if you use them inside your ROUTER) so that you can TN3270, FTP and send EMAIL from or to your z/OS.


If you want to use DB/2 and your z/OS web server, you will need to open up their ports as well. Make sure that you open them inside your ROUTER to your Hercules/zos instance, NOT your local PC's IP. In my case it's 192.168.1.66 (my PC itself is 192.168.1.69), don't mix them up, really odd things happen.


There are lots of other little fine tuning things you can/should do, but the above changes are where most people mess up.


Lately I have noticed that a lot of people are messing up on the actual CTC device they use to connect (for me that's the E20-E23), they have some other address (that they have to look up and use) or forget to define something that Hercules can use for this, it can be a CTC or even defined as an OSA adapter. I don't think you can use the OSA as an LCS, but there are OSA setting on this site as well.



If your system is (I hope because you would probably be breaking the law otherwise) a ADCD system or some other "legal" type, then you probably have E20-E23 like me.


If you got it via some nefarious means, then you will need to generate the proper devices and that's pretty much where I draw the line because if you are breaking the law, you are on your own. If you have a legal copy, then this won't be an issue for you, and it's just a matter of the other stuff I mentioned above.



If you have more questions, feel free to contact me off list if you want, but if you keep it on the list more people will benefit from the text of what you do to make it work.
