SIMH telnet issue
Posted on March 24 2016 00:32
I'm running OpenVMS 7.3 under SIMH 4.0 beta on a Raspberry Pi (no, seriously, stop sniggering).
You can read full details of how I configured the basic system here.
And how I configured networking here.
The networking is basically working. I can ping out from the simulated VAX using:
$ TCPIP PING google.com
So the bridging is working. But, although I've enabled Telnet services on the VAX, connection is being refused. The annoying thing is that this worked yesterday, and then it stopped today.
I'm using bridging on the RPi, with the VAX's XQA0 being connected to a tap0 virtual device.
During bootup of OpenVMS, telnet appears to get started okay.
Message from user INTERnet on CROVAX
INTERnet ACP Activate TELNET Server
%TCPIP-S-STARTDONE, TCPIP$TELNET startup completed
%TCPIP-S-STARTDONE, TCP/IP Services startup completed at 24-MAR-2016 09:22:30.96
Going into the TCP/IP config utility shows Telnet as being enabled and started.
Any suggestions as to where I might start looking? I'm a total newcomer to VMS. I don't think there's any firewall on the RPi (and like I said, it worked yesterday).

1. Check show intrus
2. Check to make sure sylogin.com has world execute permission. Note that a logical name can (SHOULD!) override the default name.
3. An error in SYLOGIN can cause the login to fail.
4. An error in the user's login.com can cause the login to fail.
5. Can the user write to their home directory.
6. Check the accounting records, you may have to enable some.
You can sign up for the vms-ports project and add links. We are way behind in documentation.

If it worked, then quit, it will be in your network infrastructure. On the VMS side, shutdown TCP/IP and try re-running UCX$CONFIGURE.COM. On the PI side, rebuild the network connections.
