Hello,
I'm new to the unix environment and am trying to get a home network running.
I am connecting two computers a p3 (redhat linux) and a p1 (freebsd 4.1).
Unfortunately, things aren't working quite as they should :-) Help would be
greatly appreciated.
I have setup networking on both the computers, I don't have a firewall on
the linux machine either.
I can ping the p3 (or even ftp/telnet into it) from the freebsd machine.
However, I cannot even ping the p1 box from the linux machine. Any idea what
the problem could be?
Is it a problem with a firewall that I may have on the freebsd machine? How
can I disable it and allow all connections? Why can't I ping the freebsd
machine from the linux machine? Do I have to change something on the freebsd
machine? How can I allow pings?
Here is the output of netstat -rn AND ifconfig on both the machines.
