Source quench Received.

[Chandramohan Achar]

Hi ,

Very often we get this ICMP reply "Source quench Received" when we ping to production servers at onsite. This part has been conformed that message is from server and not fron network gateway.

I have understood the conecpt of this ICMP reply "Source quench Received".

but to troubleshoot on server side, whcih has hp-ux 11.i OS running on to it, I need to know various commands of networking on hp unix.

It would be great help if u can tell the procedure to find out the cause for this and how fix the same.


Thanks and best regards

Waiting for the mail.

Hi,

that message is about ICMP packets
you should verify

# ndd -get /dev/ip ip_send_source_quench

Maybe it is 1, then in order to solve that message you can set it to 0:


# ndd -set /dev/ip ip_send_source_quench 0

and verify that /etc/rc.config.d/nddconf file sees as follows

TRANSPORT_NAME[X]=ip
NDD_NAME[X]=ip_send_source_quench
NDD_VALUE[X]=0

To know more about "Source Quench" see RFC1812 on Chapter 4.3.3.3:

ftp://ftp.rfc-editor.org/in-notes/rfc1812.txt

I hope this helps you.

Best regards,
Ettore
