Multinet IP Change Problem

[PreZ]

Hi,

Recently we changed ip in our server with version,
MultiNet V4.4 Rev A-X, AlphaServer 4100 5/533 4MB, OpenVMS AXP V7.2-2.
The server is resolving in DNS and also I can telnet and login to the system.
But when I try to ping the host from same host , it is giving me the old ip.

Example :
If i have changed the ip from x.x.x.x to y.y.y.y
Server1$telnet server1.ser.com

I am able to login.

But,
If i try to ping the server with fqdn,
server1$multinet ping server1.ser.com
PING Server1.ser.com (x.x.x.x): 56 data bytes
It is trying to get the old ip address.

If i try to ping the server without fqdn,
server1$multinet ping server1
Ping Server1.ser.com (y.y.y.y) : 56 data bytes
64 bytes from y.y.y.y: icmp_seq=0 time=0 ms
It is reachable.

I have checked the multinet:hosts.local file entry also. It is not there.

Kindly please let me know how could i resolve this problem.
Also how could i release port in multinet.
i want to release the connection in port 1521

Thanks,
Prem

also how to flush the cache in multinet.

It is not pinging only if i use in Capital letter for hosts.
SERVER1.SER.COM

It sounds like you may have changed the IP address with MultiNet Configure/Network (good) and the name server (NAMED_SERVER) is getting the right information because its configuration files have been updated.

I suspect that PING is using the old HOSTS.TXT though. Update MULTINET:HOSTS.TXT with the new address, then recompile it with
$multinet host compile
and install the new tables with
$@multinet:install_databases

Hi Richard,
Thanks.
I checked the Multinet:Hosts.txt file.
There were no entries at all.

[Richard Whalen]

There is no way to flush the cache of the name server, but you can restart it:
$ multinet netc/host=127.0.0.1 domainname shutdown
$ multinet netc/host=127.0.0.1 domainname start

You'll want to check your name server configuration and where it eventually gets its answers from for hosts in your domain.

Hi Richard,


Sorry to pop in here.

Im working with Prem here on the same problem.

I jus tried the command you have give above and please find the out put below.


AAAAA_SYSTEM> multinet netc/host=127.0.0.1 domainname start
Connected to NETCONTROL server on "127.0.0.1"
< AAAAA.MERCK.COM Network Control V4.4(10) at Tue 3-Aug-2010 11:09AM-EDT
Error: Service "domainname" not found

Please suggest.

That would imply that the name service isn't running on this system. To see what MultiNet services can be controlled from the netcontrol application do the following:
$ multinet netc/host=127.0.0.1 netc list

To see the address of the name server that the system using:
$ show log multinet_nameservers
