 Posted: Mon May 17, 2004 1:57 pm Post subject: Unnumbered interface *SOLVED* |
 |
|
Guys,
I've done a search but not found an answer that works 
I'm building a gentoo snort box with 2 nics.
Eth0 is my management nic configured with static ip on a 10.1.x.x subnet
Eth1 I want to assign as an unnumbered interface to do my snort scanning.
How can I configure an interface to be unnumbered? I've tried commenting out eth1 in /etc/conf.d/net but that won't let me bring up the interface.
Any ideas?
Paul

Could you just bring it up with no IP address?
e.g.
I've also seen some articles on making 'recieve only' ethernet cables, which is probably overkill but would ensure that _nothing_ goes out on that IF. |

Bringing up the interface with
ifconfig eth1 up worked to a fashion, however anything trying to use the interface always started with
| Code: | * Please make sure that /etc/conf.d/net has $ifconfig_eth1 set
* (or $iface_eth1 for old-style configuration) |
If found that if I set the eth1 variable in /etc/conf.d/net to
| Code: | | iface_eth1="0.0.0.0" |
The net.eth1 is able to bring up the interface unnumbered and anything else using the interface doesn't error. |
