Some commands of interest maybe "ifconfig -a", "ping ", "route -nee" and "netstat -nlp". Please read the Networking HOWTOs for more help.

Hi,

http://www.google.com/search?q=Linux+network+troubleshooting+howto

try also:
#ethtool eth

To check your NIC settings "speed" "duplexmode" "autoneg" are correct/ match the settings on your switch.

You have ethereal in GUI, this will use many of the console command that could tell many things about lan (netstat, route, ipconfig ...)

I wrote a nice article about that but in czech so it's pobably usele for u if you don't undestand czech anyway...

ifconfig
ping
traceroute
tcpdump

are basic think almost on every UNIX

fping
icmpquerry
hping
tcptracerout
nemesis
wireshark

are OpenSource tools with greate power, they allow you to send any packet you are thinking about. And listen for answer.

But you must be very well educated in TCP/IP architekture.
