No. You should install linux because you want a powerful 32 bit operating
system that is fully multitasking and multithreaded. You should not install
an OS because you want to maliciously take down a site on the net. Besides,
installing linux doesn't get you connected to the net automatically.
Consistency alert: Once again, first you say Windows 95, then you say Linux.

One of the best ways to crack into a system?! Read previous replies.

Finger is just about the most minor security concern there is. The admin
of my ISP allows finger, and is quite security conscious. He doesn't
have the luxury of disabling most of the ports, so you can use
finger on his server.

What evidence?! You just showed that you connected and received an
ascii banner. That is NOT a sign of a firewall. The fact that many
firewalls are passive will make determination of a firewall's
existance somewhat difficult.

At no point were you "logged on" using the finger service. You simply connected,
made a query, and received the output. That does not involve any login or
In real life: ??? is a common message displayed if the system doesn't know
who you are asking about (ie: the account doesn't exist).

"with calls to root". Are you referring to a SUID program? Or a program
running AS root? Finger is NOT SUID, and does NOT need to make calls to
root. This can be referenced in the 'ffingerd' documentation.
