share internet connection with only one network interface

the below command create a alias for share your internet connection with another.

ifconfig eth0:1 192.168.0.1/24

Its obviously necessary too activate the iptables post-routing and ip forwarding, as root:

modprobe iptable_nat iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE echo 1 > /proc/sys/net/ipv4/ip_forward

Be sure that the alias 192.168.0.0/24 is not your active real ip range

A way not so simple but functional for print the command for the process that's listening a specific port.

I got the pid from lsof because I think it's more portable but can be used netstat

netstat -tlnp

turn lines in columns in csv format

searching for sed to make a csv, I found the solution from Mr. Stolz in http://funarg.nfshost.com/r2/notes/sed-return-comma.html

you can also to use:

My curiosity has forced me to make it using only sed.

Maybe useful... or not... :-S

list all opened ports on host
