TCP/IP Services for OpenVMS

Whats the quick and easy way to change an IP Address/Subnet Mask/ Default Router-Gateway?

I was just going to run
$SYS$STARTUP:TCPIP$CONFIG
Options :-
Stop IP
Config core env
Interface (then) Routing <--Options
Start ip

What do you think ?

We run the following version of OpenVMS and IP

$ ucx show version

HP TCP/IP Services for OpenVMS Alpha Version V5.4 - ECO 5
on a AlphaServer ES45 Model 2B running OpenVMS V7.3-2

$

Standalone ES45 ...
DECNET IV

That sounds o.k., I even think stopping is not neccessary, the new settings will take effect on the next startup.

Kevin,

you may first need to remove the current local host name from TCPIP$HOST.DAT ($ TCPIP SET NOHOST xxx), if you want to keep the name and just change the IP address.

I normally delete the old interface with TCPIP SET CONF NOINT xx0 and then run @TCPIP$CONFIG to configure the interface.

Re: TCP/IP Services for OpenVMS

Kevin,

this may be completely superfluous, but, when you are going to execute this, _DO_ use a session that is in NO way dependant on TCP/IP !!!
(use the console, or a DECnet connection, or a LAT session, or, ... ANYTHING but TELNET or SSH or...

Proost.

Have one on me.

Kevin,

To somewhat clarify Jan's comment: Please verify that the path used by your connection DOES NOT go through the IP Stack in any way (Yes, I have seen people take the advice to use DECnet; only to discover that their DECnet connection was through an IP tunnel).

Thanks for the pointers on this.

Yes I will do the config via the console.

Re: TCP/IP Services for OpenVMS

On those occasions when I have had no choice but to remotely reconfigure or restart TCPIP, I have put all of the commands needed into a batch job and 'submit/user=system', then login again after the changes...
