Sockets SO_RCVBUF

I have written a simple TCP client/server. I would like to change the TCP
receive buffer on the server side, to see performance differences. I am
trying

err = sock.setsockopt (socket.SOL_SOC KET, socket.SO_RCVBU F, 4096)

but that doesn't seem to actual change the buffer size.

The code is:

#Create a socket

sock = socket.socket(s ocket.AF_INET, socket.SOCK_STR EAM)

#Ensure that you can restart your server quickly when it terminates

sock.setsockopt (socket.SOL_SOC KET, socket.SO_REUSE ADDR, 1)

#Set the Recieve Buffer Size

err = sock.setsockopt (socket.SOL_SOC KET, socket.SO_RCVBU F, 4096)

print socket.SO_RCVBU F

#Set the client socket's TCP port number

sock.bind(('', portno))

Development is being done a Gentoo Linux box.

Any suggestions would be great!

-Thanks

Hi, For various reasons I need to how many packets are queued in the SO_RCVBUF of a udp socket. I know there are various mechanisms for detecting if there is one or more packets queued, but I cant find anything to tell me exactly how many are queued. Does anybody have any idea how to get this information. I currently need this for linux.
