Hi grebar,

sorry for the late response.

As root, use "tcpdump -s1500 -i YourNetworkInterface -nvv" (if you're using eth0, then you needn't specify that via "-i", it's the default). Depending on the usage pattern of the machine, you may see tons of output and will have to dig through it. "tcpdump" supports filtering, so you can specify that certain traffic, identified as "noise", should not be traced. See "man tcpdump" for options and more.

You cannot (hardcoded in glibc), and the delay is expected behaviour.
