[olug] Unix Tip: GET YOUR IP-ADDRESS, Omaha Perl Mongers

[Don Kauffman]

  Umm Jeff,

I did what you suggested and got this

 python -c "import socket; print socket.gethostbyname(socket.gethostname())"
10.90.0.0

I did what the tip suggested and got this.

/sbin/ifconfig | grep "inet addr" |  grep -v "127.0.0.1" | awk '{print 
$2;}' |  awk -F':' '{print $2;}'
10.90.2.237

I know why --  it hearkens back to something I had  questions on but 
never got a satisfactory answer about. I'd still like an answer because 
I don't think I've got the system set up correctly. What it amounts to 
is that I don't know how to get the hostname to pull an IP from dhcp 
when the system is starting up. The hostname seems to need a dedicated IP.
