For some reason, I cannot change the inet address of eth0 to anything else than 10.0.0.9. When I do so through the command: sudo ifconfig eth0 inet 10.0.0.X, pages, pings, etc. load for 30 seconds and then say Unknown Host or Webpage not found. What could be the issue to this?My Ethernet PCI is BCM57765, and I installed the corresponding driver (tg3).lsmod | grep tg3tg3                   164481  0 ptp                    17692  1 tg3libphy                 32268  1 tg3In the network manager,I tried adding:[eth0]managed=falseHowever it did not do anything. My /etc/network/interfaces is default, except of the auto eth0 line. I previously tried iface eth0 inet static to set static IP as a workaround, but that did not work either.iface eth0 inet static       address 10.0.0.7       gateway 10.0.0.138       netmask 255.0.0.0
Cannot change inet address to anything eth0

You have dhcpcd running and no matter the ip address is defined as static, the daemon asks for an IP to dhcp. if you have a static address, you should stop it. Otherwise, any time you change the status of the interface changing the IP, it just does a DHCP request, and is back again to the DHCP-given IP.Do a service dhcpcd stop and try it. If you wish to keep using fixed ip addresses, run: $sudo service dhcpcd stop $sudo aptitude install chkconfig $sudo chkconfig dhcpcd off
