 Posted: Tue Feb 01, 2005 10:19 am Post subject: Missing route |
 |
|
Whenever I boot up my machine, I find the entry for the default route/gateway is missing from the routing table. However, the correct gateway is specified in /etc/conf.d net. Can anyone suggest any other reason that it might not be being set, as I can't think of anything?
I can work around it by running 'route' and re-mounting NFS shares once the machine is up, but it would be better to have this working. |

is it specified in the correct way(ie with an interface)? mine looks like... | Code: | | gateway="eth0/192.168.1.1" |
the default gateway is setup in /etc/init.d/net.eth?. has anything bad happened to that file?
does it have a part like this in it?
| Code: | if [ -n "${gateway}" ] && [ "${gateway%/*}" = "${IFACE}" ]
then
ebegin " Setting default gateway"
# First delete any existing routes if it was setup by kernel ..
/sbin/route del default dev ${gateway%/*} &>/dev/null
/sbin/route add default gw ${gateway#*/} dev ${gateway%/*} \
netmask 0.0.0.0 metric 1 >/dev/null || {
local error=$?
ifconfig ${IFACE} down &>/dev/null
eend ${error} "Failed to bring ${IFACE} up"
stop
return ${error}
}
eend 0
fi

what about error messages when you system is booting?

No it does not - how strange.
I'll try re-emerging baselayout to see if that fixes it.
Thanks. |

No luck - it seems that net.eth0 is a symlink to net.lo, and this is also the case in any rc-script tarballs that I download.
Would you mind posting a copy of your complete net.eth0 script so that I could diff them, please? |

fyi: i just took a look and my baselayout is kind of old. i'm running 1.8.6.10-r1, and 1.9.4-r6 is out. there is a possibility, that they have changed this startup script. just figured i'm mention that.

Thanks - that's very different.
I have the latest baselayout. However, cramming the "gateway" code you originally posted into that seems to have done the trick, though it is far from ideal (I get some errors on boot).
Presumably, as the format has changed the gateway must be set somewhere else now... |

In the doc of the new baselayout, there is an example like this:
ifconfig_eth0=(
"172.16.26.100 netmask 255.255.255.0"
)
route_eth0=(
"default gw 172.16.26.252"
)
