slip

I'm receiving IP packets using the SLIP protocol, and I'd like to pretty-print them similarly to how tcpdump does it. My program is able to decode the SLIP protocol and create a single string containing an IP packet if necessary.

I couldn't find any relevant tcpdump command-line flags except for -r. The file format is documented at http://www.tcpdump.org/pcap/pcap.html , but it looks a bit too complicated.

Is there a Linux tool for pretty-printing raw IP packets?

Packet loss rate with iperf and tcpdump

as seen on Server Fault - Search for 'Server Fault'
I tested a line for its link quality with iperf. The measured speed (UDP port 9005) was 96Mbps, which is fine, because both servers are connected with 100Mbps to the internet. On the other hand the datagram loss rate was shown to be 3.3-3.7%, which I found a little too much. Using a high-speed transfer… >>> More

I want to process all packets with their size going through our gateway server (running Debian 4.0). My idea is to use tcpdump, but I have two questions.
