DTC replacement

Fred Martin_1 — Tue, 27 Sep 2005 13:00:33 GMT

I'm using HP's DTC48 and dtcmanager currently, with the boot information coming from an RP5450, HP-UX 11.11.

After I subnet, the remote DTC48 will no longer work, I am told that it can't traverse a subnet to get it's boot info from the server.

HP tells me there is a different model HP DTC that uses ftp to boot, and so will work across a subnet.

But if I decide to go with something else, say a 3rd party terminal server instead, how would that work? currently the DDFA software creates the ocd processes etc. needed, which I'm assuming would be of no value to a non-DTC terminal server.

The old DTC's cannot route across networks, they have to be on the same subnet.
You would need to buy the DTC 16RX and the software (if still available) for HP-UX to get it to traverse subnets to boot.
take a look here:

If you are using Cisco switches to subnet (like VLAN), then you can configure a port on the switch to be on the same lan as your host.

Right, I have a reseller that can get them for me. But I was thinking I'd just get something more modern from a 3rd party.

I'm sure that would be fine for my dumb terminals that just telnet to the server anyway, but for my line printers I'd need something that the HP-UX server could send print jobs to.

I was wondering how the server would handle that.

Thanks Rodney, no they're not Cisco. Routers are Vanguard, switches are 3COM.

Fred,

Yes, the DTC16RX (J2064A) would work. This hardware should still be available from resellers, but it's no longer available from HP. You would also need to install
the DTC16RX Manager software (J2496A) on the HP-UX 11.11 system to manage the DTC16RX.

Note also that DDFA can use ocd processes to work with non HP terminal servers but with reduced functionality and limited support from HP.

Marie.

Reduced functionality is OK I think. On my current DTCs I have dumb terminals and text-only serial printers, the printers are as generic as they come.

We dropped the DTC16 ages ago, and replaced it with a DECserver 90M

I realy like the DTC configuration interface on HP-UX, but the thing was so bloody large, heavy and power consuming, that the DECserver makes it look archaic

Enjoy, Have FUN! H.Merijn [ who wouldn't know how the DECserver would act over routers ]
