I admit the linux network system is somewhat foreign to me, I know enough of it to configure routes manually and assign a static IP if necessary.
So quick question, in the ifconfig configuration files, is it possible to add a post connect hook to a python script then use a python script to reassign a hostname in /etc/hosts and spawn off a new process to do other things once the hostname has been updated.
This is a ‘fun’ project for me to solve an annoyance in my daily routine. When I boot up my workstation in the morning, the DHCP service assigns it a IP at random. So I usually stop what I’m doing, lookup my new IP, type that IP into my laptop and get synergy running so I can share the two machines. I figure I lose 10-15 minutes a day doing this everyday of the week and I’ve never really messed with linux’s networking system so it would ultimately pan out.
I already figured my python script would have to run as root, therefore I’d store it in /root or somewhere else that’s safe. I found a similar question on stack overflow that pointed me in the direction of http://www.secdev.org/projects/scapy/index.html a raw packet toolset to work with ARP. Editing the host file is a snap… just wondering what possible side effects of trying to put this hook into a core service might cause.
Cleanest solution would be to have a DHCP server that exchanges its assignments with a local DNS server. So regardless which IP address your workstation is being assigned to, it is accessible under the same hostname.
This concept is used in every full-blown windows network as well as in any other well configured network.
