Renaming P1P5 To Eth0 Borked Network

[mcai8rw2]

ok, so I wanted to rename my ethernet card in Ubuntu 14.04 from P1P5 to ETH0. I wanted to do this because p5p1 was messing with BTsync and other media programs.

 

I naively thought that I could do this by altering the /etc/network/interfaces file, swapping 'P1P5' for 'eth0'. I tried this. It didn't work.

 

So... i put /etc/network/interfaces back to how it was:

 

auto p5p1

iface p5p1 inet static

address 192.168.90.150

gateway 192.168.90.250

netmask 255.255.255.0

dns-nameservers 8.8.8.8

 

Only now... when i reboot the PC, there is no network. And to get a network I have to manually "ifconfig P5P1 up && dhclient P5P1" EVERY time.

 

"lspci" picks up the hardware fine, and "lshw -C network" does not day "disabled" anywhere in it.

 

Please can anyone help me acheive two things:

 

1. Get ethernet to work on reboot normally.

2. Rename ethernet connection from p1p5 to eth0 so that BTSync and "other media programs" might work again.

 

 

Thanks
