Sniff My Server

[dave_kimberley]

Hi there,

I have been searching arround for weeks now, but still have not found any information.

My FC2 box connects to the Internet via my LAN, I need to snoop another FC2 server I own over the Internet, however tcpdump works but will wait on the LAN.

Is there anyway to snoop a remote host over the Internet?

:confused:

you could connect to your remote server with xnest or vnc, then run ethereal. all these apps are on the FC2 CDs. however, if you're running over a slow connection, xnest and vnc will be pretty slow.

For checking security I would start with an nmap scan (http://www.insecure.org/nmap/). RPMs come with Fedora, and there is even a frontend GUI. You can scan host and it will show what ports are open, and a lot of information about what is running.

Ethereal will show what traffic is on the network. This may not help much if your server is at a remote location.

Install it via yum (fedorafaq.org/#installsoftware). yum install nmap* Also, a nice tool found at the nmap homepage is Nessus.
