After being inspired by a forum post, I wrote a new net-scripts module (arping) which replaces the apipa module. arping also does apipa, so you loose nothing if you ever used it. apipa was basically a wrapper around the arping tools to find a free address in the 169.254.0.0/16 range, so the new module name makes more sense.
Anyway, here’s a sample config which tries to find a gateway and sets up the interface for it
netplug is a nice little daemon that detects ethernet cables being inserted and removed based on kernel netlink events. Unlike ifplugd, it doesn’t use any other tricks or work with wireless devices. However, it is much smaller and encourages kernel driver devs to use netlink events properly- which is good :)
One thing I’ve never liked about ifplugd is that it never seems to work well with the default settings and it currently runs from it’s own init script- which makes it hard to integrate into baselayout automatically.
After watching a program about teenagers twice their recommended body weight and myself being a stone or two overweight I’ve decided that if they can run a mile run every morning before breakfast then so can I! :jawdrop:OK, it’s probably not a mile as it only took 10 minutes to run around the block but it’s a good start. Especially seeing as by the end of it my lungs where searing with pain, I was feeling faint and my feet were like two bricks :barf: Which is the price you pay for being an overweight smoker who doesn’t like excercise!
baselayout-1.12.0_pre6 will now feature resolv.conf merging- basically taking the best information from active interfaces that we or dhcp has setup and merging it into one. For example
eth0 has
nameserver 1.2.3.4 nameserver 1.2.3.5 domain foo
eth1 has
nameserver 4.3.2.1 nameserver 4.3.2.2 search wibble wobble
This turns into a merged resolv.conf of
nameserver 1.2.3.4 nameserver 4.3.2.1 nameserver 1.2.3.5 search foo wibble wobble
However, if eth1 has a lower metric than eth0 (eth0 wireless, eth1 wired for example) then it becomes
baselayout-1.12.0_pre4 hit portage today. The trace_dependencies() function in /lib/rcscripts/sh/rc-services.sh has caused a few headaches for many people. Symptoms include hanging, getting things in the wrong order and other such nasty voodoo. :O
So I hacked in a toposort function which is faster then the “sort until nothing” approach we used previously. We can’t use tsort (C toposort program) as that’s in /usr/bin and isn’t available at boot time, so it’s in bash!
