After upgrading to baselayout-1.12.11 I started having network problems - while
local network was reachable for anything else I was getting 'Network
unreachable'.
After some investigation I found out that network startup script improperly
sets default gateway:
sun ~ # netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
0.0.0.0 192.168.1.1 255.255.255.255 UGH 0 0 0 eth0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
As you can see default gateway has 'H' flags which means that route is for host
(in opposite to network). Adding route manually:
route add default gw 192.168.1.1
solves the problem. In such case route shows up as:
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
My network configuration is the following:
config_eth0=( "192.168.1.3/24" )
routes_eth0=(
"default via 192.168.1.1"
)
which is exactly what is specified in net.example file. AFter some debugging I
figured out that route command for default gateway was invoked with -host
option.
Reproducible: Always
Steps to Reproduce:
1. Upgrade baselayout 1.12.11
2. Startup network
3. Try to ping something outside your LAN
Actual Results:
Network unreachable error
Expected Results:
ICMP reply

Exactly the same problem here. I reverted to baselayout-1.12.10-r5 and solved
the problem.

I can confirm that baselayout-1.12.11 works with the patch.
Thanks!

Thanks for the patch, my routing table after boot looks sane again. :)
Works here as well..
When can we expect this patch to appear in portage ?
please be patient and do not ask about "when is it going to be in portage".
this really only serves to annoy people. it'll get added whenever someone gets
around to doing so, and asking does not make any difference.
baselayout-1.12.11.1 should work fine
