incomplete headers

[Marcos Tinoco García]

Hi!
I have a server with UNIX hpux 11.11 version 1 and I run a command "netstat -p udp" the output is:

2064 incomplete headers
175 bad checksums
1904 socket overflows

what does mean it? and How I can erase it?

Thank's

You probably can clear the statistics with:

lanadmin
lan
clear

UDP packets can be damaged in the transfer, so checksums will not match. For "socket overflows" see:

IIRC it means pretty much what it says - there were datagrams arriving which didn't have complete UDP headers. Given a UDP header is only 8 bytes in size it is rather a feat. I suspect that if you were to look at the IP stats you would see a bunch about IP fragmentation too.

You might want to look at your lanadmin statistics for your NIC(s) and see if there are any FCS errors or _late_ collisions being reported that might suggest a duplex mismatch or other problems with your physical network.
