Hello...

I am interested in sniffing un encrypted telnet sessions. My only purpose in doing such a thing is I enjoy this stuff, I find it fun.

My friend and I both have networks in our rooms. We are using each other's "small" networks as honeypots. Are networks consist of....

1. Cable modem to...
2. Linux box acting as firewall/router/server to...
3. Switch to Windows box's...

I have given his linux box complete access to the services running on my linux box and he has done the same for me.

The telnet sessions aren't using ssh etc.. "no encryption at all" Any incoming packets from any other computers but his to mine and mine to his are dropped so we don't mind running the telnet.

Goal is...

To sniff log-ins/ongoing connections like....

My network's windows box will be used to start the connection to his linux box's telnet server. My linux box will be used to sniff the connection from his linux box to my windows box.

Question is...

1. What sniffer would you recommend for doing such a thing?

Also...

Any recommendations for a good brute force program for cracking telnet log in username/passwords???... Again, this is for un encrypted sessions.

Thanks.
