Re: blocking remote telnet

Excerpts from Jim Franz's message of Wed Jun 06 20:40:10 -0500 2007:
Customer's network admin swears firewall blocks port 23 (telnet, both
tcp&udp).
I tested remotely from windows, and telnet appears blocked.
But I have a couple pages of logs someone remotely trying to guess a password
for "root" and "admin", etc with existing virtual device names like
qpadev0001.

I'd like to know more information from the logs. Do they give the source
IP addresses of the clients trying to log in?

If there really is no way to get to your system from the Internet, I
guess you have to conclude that the attacks are coming from inside the
network, perhaps from some compromised machine that *is* accessible via
the Internet.
