I have a pair (EA1DS1 & EA1DS2) of Alpha server DS10 working on Open VMS 7.2-1 platform at remote site. One is running as master server and other serves as standby. I am able to ping/telnet master server EA1DS1,while I am unable to ping the standby server EA1DS2,however I am able to telnet or set host on same server.moreover I am able to ping through Windows machines.
Is it a route add problem,if so then how I am able to ping the other server while I have added the whole network route add in servers.
Could anyone help me to find the parameter responsible for making a system ping in VMS platform with decent protocol.
Regards,
Deepak Raheja

Re: ping is not working.
Further information is needed.
I presume that the original post meant "DECnet" (not "decent") protocol?
There is no direct analog to PING in the DECnet protocol stack. One can use any number of ways to see if a second node is present.
An IP (actually, UDP over IP) PING can be blocked by settings at the host or by routing/firewall rules at an intermediate node. Details of the network topology are needed to troubleshoot this question.
What does "ping through Windows machines mean"? Where are the Windows systems? How are they connected?

Re: ping is not working.
I am not able to ping by
TCPIP> ping (host name)command from One VMS machine Alpha DS10 (where Open VMS Ver 7.2-1 is installed).My UCX version is 5.0A (Quite an old one.There are several VMS machines that are in LAN.I am able to do a SET HOST (Host name).

Re: ping is not working.
Is your host name being resolved? Try
TCPIP> TCPIP PING XXX.XXX.XXX.XXX
i.e. use the IP address.

Re: ping is not working.
"I am not able" is not a useful problem
description. As usual, showing actual
commands with their actual output can be more
helpful than vague descriptions and
interpretations. You might start with this
one:
tcpip show version
> Is it a route add problem, [...]
My psychic powers are too weak to tell me how
your systems are configured.
tcpip show route
> [...] with decent protocol.
What's an indecent protocol?

SolutionPING
- name resolution issues
- firewall rules
- routing rules
- ICMP being disabled on the remote node
First, as has already been suggested, does PING work if the numeric address of the remote machine? Also, does PING 127.0.0.1 on the remote machine work (127.0.0.1 is the IP loopback address; often given an alias name of "localhost").

Re: ping is not working.
And this proves the interface to LAN IS working, and the ping problem has some reasons other than the ethernet interface, as others have mentioned.
So You can go on and replant the interface in the remote system.
On the other hand, if SET HOST means DECNET: did You reconfigure DECNET to use the new interface (EWC0) instead of the old EWA0 ?
If so, then You proved nothing!

Re: ping is not working.
$ mcr lancp show dev /char
$ tcpip show version
$ tcpip show config interface
$ tcpip ifconfig -a
$ tcpip show interface /cluster
$ tcpip show route
on both systems you've referenced.
Master/Standby: Are these systems in a cluster? Do you have an alias address that's expected to migrate between the nodes?

Re: ping is not working.
As per you asked the output of followings
$ mcr lancp show dev /char
$ tcpip show version
$ tcpip show config interface
$ tcpip ifconfig -a
$ tcpip show interface /cluster
$ tcpip show route
Please find the attached reply.
By mistake I wrote in 1st thread,decent in place of DECnet.
Hello Joseph,
I think you are considering this the old problem we discussed,this ping problem is not related to earlier one we talked(New LAN card adding . . .)
