The point is that the DHCP client on VMS is a hit or miss thing. Initially, it is much simpler to set everything up with static IPs and then move to DHCP if one is a masochist.

DHCP on the lan is useful if you have guests coming over and they want to plug into your lan. (at which point the DHCP server can serve from a differet pool of IPs thata re still within the LAN's subnet.


The Linksys uses 255.255.255.0 (/24). I think it's 192.168.1.1, but I'm
not certain.

Interesting. The 192.168 is a 16 bit CIDR as per the IP address allocation blocks., so Linksys *should* be using the whole subnet instead of just a /24.


Before zapping all the config files, and re-running TCPIP$CONFIG,
did you already run it the first time? Lots of TCPIP configuration

I have found that TCPIP$CONFIG is sometimes harder to coerce into doing what you want if there are existing config files. And if the user used the TCPIP utility to manually set things up, there is no telling how TCPIP$CONFIG would react to a partial configuration.

I'm 99.99% sure this should be 255.255.255.0 for the Linksys, only about
65% sure it's 192.168.1.*

If the router uses a /24 and your nodes are configured as /16 but are setup with IPs that fit inside the Linksys' subnet then you shoudl still be able to connect to the Linksys and configure stuff.


Don't remember if it asks for host names. It might, but they are
definitely not needed for name resolution. In fact, it *has* to
use the IP addresses, because if it only knew the host names, it
couldn't resolve them to locate the name servers :-)


I got bitten by this once , this is why I remember it. Perhaps it is when trying to reconfigure something. The TCPIP$CONFIG wants you to enter a host NAME in some cases for the bind server, and it expects you to have defined that host name in the hosts database (TCPIP SET HOST command) before invoking TCPIP$CONFIG.

But I think that for a fresh config, it accepts IP addresses.
