Re: pinging OpenVMS servers

Off topic a bit, but--

This morning I posted a reply saying pretty much the same thing as Martin's, but it never showed up here. My browser crashed perhaps a half hour later, but I can't see why that would matter.

Re: pinging OpenVMS servers

Galen,

Had that several times.

$ifconfig -a

will show your interfaces with MTU.

$ifconfig lo0 ipmtu 4096

will change it.

But I don't have your version of tcp. My version is refusing values 0 and 1. So, no idea where it came from.

Martin,

Could you give me the intstructions to remove the route.
Do I need to shut down and start TCP/IP services?

Re: pinging OpenVMS servers

Keith,

Volker already mentioned the relevant commands (and explained it better than I did).

No, you don't have to restart TCP/IP. It should immediately start to work.

Keep an eye on those routing entries. It seems that some node (possibly 10.12.10.254) announced a route to 10.12.2.1 - which your VMS machine picked up.

HTH,
Martin

Re: pinging OpenVMS servers

Many thanks to all respondents.

I have removed the offending routes from both nodes, both dynamically and from the permanent database and am pleased to report that both the ping and the Gembase problems are now a thing of the past.
