Error adding client to network IUX server

[Navin Jain]

I am trying to add a system running HP-UX 11.11 (patched to Dec 2004 patch level) to network Ignite-UX server running B5725AA version B.6.1.44. Using add_new_client command on the IUX-client system, I am getting an error message:

/opt/ignite/bin/add_new_client -f -s tnt2uds1
ERROR: Client could not ping Ignite-UX Server: "tnt2uds1 "

Debugging the add_new_client script I found the error message is coming from the command:

ping_out=$(ping "$1" 1024 2 2> /dev/null)

It seems that pinging from client to IUX server with 1024 packet size is failing.
I tried to ping with different packet sizes from client to IUX server with the following result:

Packet Size Ping Result
64 Ok
512 Ok
1024 failed
2048 Ok

Questions:

1. Why pinging with packet size of 1024 fails, where as all other packet are successful.
2. Even after changing the add_new_client to use different packet size, the make_net_recovery command fails with the same message. Does the packet 1024 is used for NFS optimisation.

Has any one seen or heard this error with pinging with different packet sizes.

Hi Navin,

I believe the ping failure with 1024 packet is a network issue. You might want to check with network admin. It might be a case in the network, 1024 bytes packets are being dropped. Incorrect configuration maybe at firewall?

However if you change the packet size in the script , you should be able to add the client.

I don't think there is any relation of packet size 1024 bytes with NFS optimization.
