Source Quench received

Ajay_3 — Mon, 15 May 2000 03:06:03 GMT

Hi
We are having HP 9000 R-390

When I am pinging to the LAN interface I am getting response Source Quench received.
This error is intermittent but for most of the packets
My LAN card is set for the 100 MBPS and I am sending a request from a 100 MBPS NT Machine.
I checked the error from NT techmedia it says that Destination buffer full will give this error.
So how do I solve this problem on HP UNIX 11.X?

Regards,

Vijay

As far as I know there is no patch for this yet but this should work

# ndd -set /dev/ip ip_send_source_quench 0

As far as I heard, there is no solution (read: patch), only methods to suppress the error-message :

1/ ndd -set /dev/ip ip_send_source_quench 0
This command will do the trick until you reset the system.

2/ a more permanent solution (you'll survive the reboot): add following lines to /etc/rc.config.d/nddconf :

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

=> You have to substitute INDEX with a value depending on what other entries are
in this file.

There is no problem...

in the RFCs source quenches were planned to adjust speed of two communication partners. But this did not come out.. so it is just useless...

Do not bother it at all!!!
