 |
|
after emerging the latest stable packages today (since nov 27) my (multiple isp) shorewall setup was broken.
| Code: | /etc/init.d/shorewall start
* Starting shorewall ...
RTNETLINK answers: File exists
ERROR: Command "ip -4 route add table 1 127.0.0.0/8 via 127.0.0.1 dev lo" Failed
/usr/share/shorewall/lib.common: line 113: 6929 Terminated $SHOREWALL_SHELL $script $options $@ [ !! ]
* ERROR: shorewall failed to start

I found that I had a loopback route which I suppose wasn't there before, and it's added when starting net.eth0
| Code: | Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.0.0.0 * 255.255.255.0 U 0 0 0 eth0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo <-- added when starting net.eth0
127.0.0.0 localhost 255.0.0.0 UG 0 0 0 lo <-- added when starting net.lo
192.168.0.0 * 255.255.255.0 U 0 0 0 eth0
x.x.x.x * 255.255.255.255 UH 0 0 0 ppp0 |
I have no clue what the root cause is, for now having removed net.lo from startup which resolves the issue.
I suspect it's the update to openrc-0.12.4 or my system is misconfigured in some way.
Can anyone shed some light on this?
