Just curious, my Slack 9.1 sits behind a router and has a rfc 1918 ip
address/net. The /etc/rc.d/rc.inet1.conf is set to 644, yet I have
normal intra/internet access. I'm assuming because it's read as a
config file that it only needs to be 755 if I should want to source it
directly? Is this right? If not, where is my ip address and gateway
kept?

No big deal, just trying to keep track of things.

Best regards, and tia...
