Using LCS interface and getting TCP error 10061

Rate this Message:
I am trying to use TN3270 software (Tom Brennan's Vista) to connect to
MVS. I have define an LCS device on E20 with IP 10.1.11.24. This the same setup we utilized on our Flexes system without fail. With Hercules we seem to get a TCP error 10061, which seems to indicate that the host has rejected the connection. I have tried several configurations without any success. Any help or thoughts would be greatly appreciated. This is Hercules 3.06 running under SLES 11. Also, I have configured the two NICs, one with and IP of 10.1.11.21 and the other with 10.1.11.24. I have even reversed these between the two adapters with the same results. Cheers, Tom Dunlap |

Can you send the first 60 or so lines from the LOG as Hercules comes up.
Also the relevant lines from the configuration file. Also your network configuration and Ip addresses.

Tom,
I hate it when that happens. Conceptually, everything is the same, except for one little thing, but it just won't work. Alas, I'm afraid were going to have ask a bunch of silly questions to tease out the answer. 1) Is the LCS device defined on a pair of channels, presumably E20 and E21? 2) When your TCPIP is running under MVS under Hercules, does a tun0 device show up in your routing table on the SLES system? 3) Does the TCPIP software come up cleanly under MVS. (I'm more of a VM person, so I'm used to looking at the console of the TCPIP virtual machine. I have to believe that all that good information is captured somewhere in MVS. Maybe SYSPRINT?) 4) Can you ping the MVS machine from the SLES machine? 5) Can you access the MVS machine with an X3270 client from the SLES machine? If you can let us know, I'll scratch my head a bit and see whether I conjure up some possible things to check. Jim BTW, VISTA is *very* nifty. --- In hercules-390@..., Thomas Dunlap <thomas.dunlap@...> wrote: > > I am trying to use TN3270 software (Tom Brennan's Vista) to connect to > MVS.

Jim,
I have attached a "zip" file with 5 TXT files that contains the information on my configuration. The SLES configuration is as follows" eth0 Firewall disabled MTU 1500 10.1.11.21 mask of 255.255.255.0 eth1 Firewall disabled MTU 1500 10.1.11.24 mask of 255.255.255.0 I can both PING and TRACERT to the two addresses listed above. I am able to logon to MVS from an X3270 session running under SLES. There were no errors when I start TCPIP or TN3270 address spaces under MVS. It seems to be related to trying to connect through either NIC adapter. I even tried FTP and received an error that the connection was rejected by remote host.

Tom,
Hmmm... SLES has both devices, eth0 and eth1, defined to it at 10.1.11.21 and 10.11.1.24, respectively, and your MVS has 10.1.11.24 defined to it, too? My first guess is that you need to enable proxy_arp and give your MVS a different IP address. There may be a way to dedicate one of the NIC's to Hercules, but I have to toss that one out to the group. But, if SLES is reporting both NICs and is reporting an IP address for each, that pretty much has to mean that SLES has both and Hercules has none. Your zip file didn't make it (Fish explained why in an earlier post), so I'm working blind here, but I will hazard the following offering: 1) Change the IP address on the TCPIP under MVS to something new, like 10.1.11.25. 2) Verify you can still ping and X3270 to MVS at the new address 3) Enable proxy_arp on one (or both) NIC's: sysctl -w net.ipv4.conf.eth0.proxy_arp=1 sysctl -w net.ipv4.conf.eth1.proxy_arp=1 4) Then try VISTA from across the wire to MVS.

Suggest you get the Mainframe parameters correct first - since you can ping,
Only after that and it still doesn't work you can move on to the LCS. But for starters - remove the extra device in the configuration, PROFILE.tcpip --------------- IN ZOS you don't put the telnet parms is the TCPIP profile but in the TN3270 Profile. You should be getting a message about that. Remove the section telnet parms. Remove the gateway parms and the default net parms and use the following: BEGINROUTES ROUTE 10.1.11 255.255.255.0 = ETH1 MTU 1492 (that's your local lan) ROUTE DEFAULT 10.1.11.11 ETH1 MTU 1492 (that's your gateway to theworld) ENDROUTES In the reserved ports section you are reserving port 23 for a server called TN3270 Is the job are you starting TN3270 or TN3270A? Name and port that you reserve must match the job you submit So check the startup to see that you are starting the proper procedure In the TN3270 Configuration you have some errors.
