crap
I meant I can access myLinux machine through telnet, ftp and XDMCP from my
internal network, however I cant do any of it from the internet. I want
to be able to do it. I have pmfirewall installed, but I also have
fbuilder installed, and it might be fbuilder however I have no idea how to
get rid of it(fbuilder) and any scripts.
(My linux machine is my connectionr(firewall) to the internet
Thanks
