My DSL router modem is at 192.168.123.254. I have an HDHomerun |
| 2 |
network TV tuner that insists on coming up somewhere in the 169.254.X.Y |
| 3 |
block. Up until upgrading from 32 to 64 bits, I was able to see a 2nd |
| 4 |
eth0 (i.e. eth0:1) using the following /etc/conf.d/net setup... |
| 5 |
|
| 6 |
config_eth0=" |
| 7 |
192.168.123.251/29 broadcast 192.168.123.255 |
| 8 |
169.254.1.1/16 broadcast 169.254.255.255" |
| 9 |
routes_eth0=" |
| 10 |
default via 192.168.123.254 metric 20 |
| 11 |
192.168.123.248/29 via 192.168.123.254 metric 0 |
| 12 |
169.254.0.0/16 via 169.254.1.1 metric 0" |
| 13 |
|
| 14 |
The 2nd interface is no longer being set up. As amatter of fact, it |
| 15 |
appears to be totally unavailable. E.g.... |
| 16 |
|
| 17 |
[d531][root][~] /etc/init.d/net.eth0 stop |
| 18 |
* Unmounting network filesystems ... [ ok ] |
| 19 |
* Bringing down interface eth0 |
| 20 |
[d531][root][~] ifconfig eth0:0 192.168.123.251/29 broadcast 192.168.123.255 |
| 21 |
SIOCSIFNETMASK: Cannot assign requested address |
| 22 |
[d531][root][~] ifconfig eth0 192.168.123.251/29 broadcast 192.168.123.255 |
| 23 |
[d531][root][~] |
| 24 |
|
| 25 |
So my system doesn't support even the concept of an alias for eth0. |
| 26 |
Looking at the ifconfig manpage... |
| 27 |
|
| 28 |
interface |
| 29 |
The name of the interface. This is usually a driver name fol- |
| 30 |
lowed by a unit number, for example eth0 for the first Ethernet |
| 31 |
interface. If your kernel supports alias interfaces, you can |
| 32 |
specify them with eth0:0 for the first alias of eth0. You can |
| 33 |
use them to assign a second address. To delete an alias inter- |
| 34 |
face use ifconfig eth0:0 down. Note: for every scope (i.e. same |
| 35 |
net with address/netmask combination) all aliases are deleted, |
| 36 |
if you delete the first (primary). |
| 37 |
|
| 38 |
I see "If your kernel supports alias interfaces". During the |
| 39 |
upgrade, I built the kernel from square 1. I already ran into problems |
| 40 |
with not enabling FUSE in the new kernel, which killed MTP until I |
| 41 |
enabled it. I wouldn't be surprised if I've disabled some kernel |
| 42 |
parameter which is required to enable interface aliases. I didn't see |
| 43 |
anything obvious in "make menuconfig". A Google search turned up a |
| 44 |
gazillion examples of "how to create an alias using ifconfig". That's |
| 45 |
not what I want. I want the kernel setting that allows creating alias |
| 46 |
interfaces. |
