Re: Source Quench received

SOLVED

Am trying to ping from Windows to HP-UX and am geting the following message

Source Quench Recieved

But the server is up and running fine.

RFC1812 is only talking about routers not host and states
that these ICMP messages should be limited:

A router SHOULD NOT originate ICMP Source Quench messages. As
specified in Section [4.3.2], a router that does originate Source
Quench messages MUST be able to limit the rate at which they are
generated.

2. We would suggest to disable the Source Quench errors and then check with the ping response
How to disable source quench?
*****************************

You can disable source quench by executing this command:

ndd -set /dev/ip ip_send_source_quench 0

To disable Source Quench so that it can survive a reboot, modify the /etc/rc.config.d/nddconf file as follows :

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

Where X is the next logical numerical sequence in a table of values, with X starting at 0.

Once the source quench is disabled (with ndd) then perform the same ping test again and let me know the results.

Thanks a lot !! I am able to ping to the server..

What does X implies in nddconf file.

Its an array
If the file is all hash then your arry will start with 0.
[0]

ok. will replace the X with 0 .. thanks avinash

I wouldn't advice disabling source quench, because it is an symptom.

Under normal operation, they shouldn't be generated by hp-ux alot.

Seeing source quench from an hp-ux can be correlated to low memory on the system, check with top, if free memory is around megabytes, expect problem with connectivity. This would also display symptoms like hanging ssh or X11.
