57.27 Network Debugging

Useful tools include ethereal which is a graphical interface to the same output you might get from tcpdump. A typical usage of tcpdump is:

  # tcpdump -l -i eth0

The -l will ensure each newly generated line will be output immediately (rather than cached). The -i identifies the interface to monitor.

The pktstat package provides terminal top-like view of network connections. This is useful to provide an instantaneous summary of network conenctions. The -F option will expand hostnames, rather than listing just the first part of a hostname (without the domain name).
