I've been trying to configure another version of linux in virtualbox, and I want to connect it to my network using the bridged adapter option by bridging it to my wifi. Its been taking me a while to figure out how to do that, but on the way I needed to edit my
/etc/network/interfaces file (on my host system). There, I saw that it looks like I only have one interface listed:
auto lo iface lo inet loopback
From what I understand, which to be honest isn't much, I should have at least 3: the loopback, eth0, and the wifi. When I run
ifconfig I get, the three interfaces, though again there's an abnormality: my wifi interface isn't named
wlan0 but rather
eth1. The output is (censored a little for internet safety):
eth0 Link encap:Ethernet HWaddr --:--:6f:70:c3:f5 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:41 Base address:0x2000 eth1 Link encap:Ethernet HWaddr --:--:00:df:bf:a2 inet addr:192.168.1.3 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::7ae4:ff:fedf:bfa2/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:408173 errors:41 dropped:0 overruns:0 frame:534242 TX packets:246382 errors:32 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:464348078 (464.3 MB) TX bytes:35404570 (35.4 MB) Interrupt:17 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:8896 errors:0 dropped:0 overruns:0 frame:0 TX packets:8896 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:740380 (740.3 KB) TX bytes:740380 (740.3 KB)
I haven't messed around much with networking, so I don't think this is something I did. Why are my interfaces so strange? If I add an
wlan0, what will happen to the interfaces that
ifconfig is already showing? Where are those located?
The instructions I'm following that led my to look at
/etc/network/interfaces are here: http://codesupply.net/content/setup-bridged-networking-virtualbox-ubuntu-1110 though I'm running ubuntu 12.04.
Also, my wifi is working on my host OS, and if I use NAT it works on my guest OS, just not when I use the bridge adapter.
