TCP/IP Internet interface error - temporary error - hosts

Since installing the latest TCP/IP ECO V5.4 for Alpha OpenVMS 7.3-2 I have been experiencing problem with host names, please see FTP example below, similar problem with RSH.

Anyone have any idea why?

Rather than saying "latest", show the output
from "tcpip show version".

Also, you might get more help sooner if your
posting actually showed the problem.

Original posting did include further information, but this web site was repeatedly failing and running very very slowly and I didn't even realise that the post had eventually worked.

Re: TCP/IP Internet interface error - temporary error - hosts

Good morning Peter

Obviously need more info on this one...

I would use TCPIP$CONFIG and go through the interface configuration and check the state of the required services.

Then, enter into TCPIP> and do
sho interf /fu
sho service

and check the results.

Does Telnet work, in or out?
Does ping to an external node work?

Was anything else changed at the time of this upgrade, eg. the ethernet switch and/or cable?

Use $MC LANCP sho dev eia0 /char
Check line speed, media and Duplex???

Good luck

Thanks for the response.

Everything works fine, including FTP and TELNET and SSH both in and out, and seems normal if I use IP addresses.

However, any attempt to use a host name on an outgoing connection fails with the error shown.

As far as I am aware the only system level change was installing the ECO and rebooting.

Re: TCP/IP Internet interface error - temporary error - hosts

HAve you tried ...
1
Add a NEW entry to the host file, say a pc, and do a ping to the name.

2
How much of a job is replacing the "host file".

A question.
Is the service BIND in use on the VMS box?

Re: TCP/IP Internet interface error - temporary error - hosts

Same results with a new entry to the hosts file.

Tried renaming the host file and running tcpip$config (which created a new file) and adding hosts, same result.

Bind is not configured.

Trace route reports:

"The name could not be resolved this time. Future attempts may succeed."

Peter,

Try reloading the BIND database using

$ tcpip set name /init

otherwise check if bind resolved enabled

$ tcpip show name

Thanks for the response.

As I mentioned above, Bind is not configured.

$ tcpip set name/init
rndc: neither TCPIP$ETC:RNDC.CONF nor TCPIP$ETC:RNDC.KEY was found. Use
'$rndc_confgen -a' to generate rndc.key or '$rndc_confgen' to generate rndc.conf

$ tcpip sho name

Peter

BIND is not in use which is fine! I would leave it that way!

It's an interesting problem....

1
Check the file security on tcpip$hosts.dat
Owner is SYSTEM with W:RE protection.
2
Dare I ask, did you do a reboot after the patch?
