Rlogin ucx device without process ?

Wim Van den Wyngaert — Tue, 08 May 2007 02:02:41 GMT

See enclosure.

1. Why isn't the process id mentioned in the bg device ?

2. Why are the counters of bytes send/rec not increased (while I show output I would expect traffic) ?

VMS 7.3 with TCP 5.3 eco 2.

Is there another device connected to this BG device? (I don't have a test config handy to duplicate this sequence right now.)

These BG devices are quite often part of a driver stack; there's some other device (eg: a TN device) that's the point of I/O contact for the particular network activity. Find out if and what device the rlogin is operating with, and see if that is logging traffic.

As for why BGDRIVER doesn't account for stuff, you'd have to ask the HP TCP/IP Services team. If I were guessing here, it's because the upper-level driver(s) connected here are using the ALTSTART and bypassing the usual sorts of counters in the lower-level drivers. Whether or not this is intentional and appropriate is up to the team to determine.

There is a TN device.

The tcp counters are however updated.
For telnet the counters are even zero !
And the counters are visible on the source node. So, only the destination node shows nothing.

Hi Wim

I assume this problem is related to the "alias" problem...... and I'm trying to fathom what you are trying to do!

In this case I would ask ... would RSH or adding a second ethernet to node A solve the problem.... TEll me more.

No. I need to move the IP address with the application to another node (yes, not cluster aware). So, the world thinks were on address 1 but address 1 can be assigned to wathever node.

Another thing we could use it for is to move sybase servers (with their alias) around without modifying our worldwide clients.

BTW : we don't use DNS.
