How to switch between network interfaces from console?
Solution 1
If both interface are configured in /etc/network/interfaces
you can use
sudo ifup eth0
to bring eth0 up and
sudo ifdown eth0
to take eth0 down
Solution 2
Normally I use
sudo ifdown eth0 && ifup eth1
sudo ifdown eth1 && ifup eth0
The 1st stops eth0
and starts eth1
and the second does it the other way around.

I've installed Debian in my VirtualBox (my host OS is Ubuntu). And there I configured two network interfaces: eth0 as NAT, and eth1 as Bridge.
NAT I need to have access to the internet in virtual OS, but Bridge I need because I want this virtual OS to be a part of my local network.
How to switch from these network interfaces? For example now I use eth0 (NAT), but some time later I need to turn off eth0 and turn on eth1.
P.S. There is no Desktop Environment in guest OS (Debian), so I need to do this in terminal.
Thanks in advance.

ifconfig eth0 up/down
works fine although I guess some prefer theip link set eth0 up/down
now. -
user1356805 over 12 yearsI've tried this before asking a question, but it didn't work. But thank you for noticing that both interfaces should be configured in
/etc/network/interfaces
. The second one wasn't configured by default, so I've added a few lines in/etc/network/interfaces
file and it works now.
