Remote Packet Sniffing

Postby jargon » Sun Oct 26, 2003 12:34 pm

Is it possible with current stuff like tethereal / tcpdump to monitor packets on a remote machine across the Internet. Perhaps monitoring the remote telnet port.

If so , I would appreciate it if anyone can help me with the tethereal command, can't seem to get anywhere w/ tethereal,

Brother... u'r question is not clear... anyway

There are many scenarios on internet or intranet or any type of network, i am putting here some tools which are helpful...

Xcat - Ip Monitor
by ComSec at Government Security Forum

this is a handy tool for network testing...if you decide to test your server against DDos attacks then this tool will monitor your up or down times...keeps an eye on up to 10 servers,pc,routers is a ..big plus

if your collegue uses a static IP then you will know when he comes on line with this can set the refresh rate to your needs... also handy if your under attack and the idiot is not using a proxy.

could be used in co-ordination with other security tools

i have tested it and it works fine

its free and only 9KB

Monitor Enterprise Network

please guide me... thx

ssh tcpdump -np not port 22 ? heh.

sorry, i haven't used tethereal.

another way to do this is to use a managed switch that has lets you copy one port's traffic to another port, where your monitoring machine sits. that's a more transparent approach.
