Howdy,
I'm tearing my hair out. My /etc/conf.d/net file is as follows:

The resulting ifconfig looks like this:

Note the very weird entry for eth0:0.
Yes, I did put all those x's in all the addresses on purpose.
In case you're wondering, putting the addresses on their own lines instead of just using spaces doesn't make a difference -- I've tried it both ways. It's just easier to read this way.
Also, if I comment out the broadcast_eth0 and netmask_eth0 lines I get broadcasts of x.x.x.255 and netmasks of x.x.x.0 for everything except for eth0:0, which comes up with the proper x.x.x.207 and x.x.x.240 -- another weirdness.
I've tried a lot of combinations. Is there something I'm doing wrong or is there a bug in the net startup script? (I'm looking through that next)
Thanks in advance. |

I tried to do simulate your problem and had similar symptons.... aditionally, I had problems to shut down the network plus some SIO.... errors.
It seems that something is wrong there --- the scripts or the sintax to write the configuration file... |

It is seemingly a bug in /etc/init.d/net.eth0. Lines that say something like:
| Code: |
aliasbcast="$(eval echo \$\{broadcast_${IFACE}\} \| awk
\'\{ print \$${num} \}\')"
...
aliasnmask="$(eval echo \$\{netmask_${IFACE}\} \| awk \'
\{ print \$${num} \}\')"
|
should actually be:
| Code: |
aliasbcast="$(eval echo \$\{broadcast_${IFACE}\} \| awk
\'\{ print \$$((num+1)) \}\')"
...
aliasnmask="$(eval echo \$\{netmask_${IFACE}\} \| awk \'
\{ print \$$((num+1)) \}\')"
|
Note: for a single alias the code in net.eth0 will work OK. It breaks when there are multiple aliases, as you do.

| Thus, I think you should submit a bug report. |
