Need to update /etc/hosts every time I connect to network because of dynamic IP

  • 772

Every time I connect to the network at work my device gets a new IP address which makes it /etc/hosts/ invalid and my hostname becomes unreachable.

I was looking for a way to set /etc/hosts automatically every time I reconnect and I came across dhclient-scrip.

I am pretty new to Ubuntu world and honestly I got lost through all this :)

All I need is just to update the IP of my local hostname when my local IP changes.

Thanks
EDIT: here is my /etc/hosts

128.141.239.50 mtahawi.comp.com mtahawi
127.0.0.1 localhost
127.0.1.1 mtahawi

so the problem is: the IP I am mapping to my hostname mtahawi.comp.com is changing when I reconnect.
I forgot to say I am using a WiFi.

  1. Why do it the hard way?

    Bind your MAC to an ip or use address reservation. Every server should have a static ip for more than just the reason you have.
