After some time offline I've reinstalled NSLU2 OpenWrt 10.03.1 and NanoBlogger 3.5RC1. The oleo.ath.cx was moved to oleo.bash.si due to non-free change from DynDNS.org last week.

Reinstalling OpenWRT backfire requires one to have complete /etc backup as LuCi does backup only important files and thus misses custom scripts. Reinstall procedure for Optware can be scripted as:

# 
sed -i -e "s|src/gz*|src/gz packages http://downloads.openwrt.org/backfire/10.03.1-rc3/brcm47xx/packages" /etc/opkg.conf
grep -vq "dest opt" /etc/opkg.conf && echo "dest opt /opt" >> /etc/opkg.conf
opkg update
opkg install kmod-usb2 kmod-usb-storage kmod-fs-ext3
opkg install e2fsprogs
test -d /opt/var/lock || mkdir -p  /opt/var/lock
opkg install libpthread
opkg install -d opt libstdcpp 
mkdir /opt /home
swapon /dev/sda2
mount /dev/sda1 /opt
mount /dev/sda3 /home
cp /opt/etc/usbmount /opt/etc/init.d/
/etc/init.d/usbmount enable
/etc/init.d/usbmount restart
cp /opt/etc/profile /etc
tar x -vz -C /home/backup/oleo/ -f /home/backup/oleo/etc-20100913.tar.gz
cp /home/backup/oleo/root/.* /home/backup/oleo/root/* /root

In our village I've been active mostly on wireless forum that was inspiring us for some time. We've taught that we can create community of wireless access points to share bandwidth. Besides Begunje we went also to nearby village Selšček and Topol. In the era of greatest enthusiasm we've had up to 30 computers interconnected. We faced technical problems, that compromised reliability of such network. Although this problems were solved by better antennas after a two years people just did not want to cooperate any more and went standalone. As I did not see technical problems my conclusion to this is: You can fix and problem except people mind. Now that even a forum died and it does not seem to be brought back I am putting backup of it on this website to remember all that fun time we've had with wireless. At that time I've started as Optware developer at NSLU2 website. I've learned a lot. And I am happy for that. But also got a lesson from a local people. I hope that they got it too.

Please follow the following link to enter backup of the Begunje WLAN forum. It's purpose is archival only and remembrance of great times now that official forum administred by Matej is down for at least half a year..

Our server that lives from version 4.11 get hit with the following error when upgrading from 7.2 to 8.0

If you have invalid mount options, reboot, and first try the following from
the loader prompt:

     set vfs.root.mountfrom.options=rw

and then remove invalid mount options from /etc/fstab.

Loader variables:
vfs.root.mountfrom=ufs:/dev/da0s1a
vfs.root.mountfrom.options=rw,userquota,groupquota,acls

Manual root filesystem specification:
  :  Mount  using filesystem 
                       eg. ufs:/dev/da0s1a
                       eg. cd9660:/dev/acd0
                       This is equivalent to: mount -t cd9660 /dev/acd0 /

  ?                  List valid disk boot devices

After many hours of figuring the problem the following line solved the problem:

dd if=/dev/zero of=/dev/da0 oseek=1 bs=512 count=1

But before getting there I needed to boot with the memstick FreeBSD as booting the old kernel did not allow writing to the partition table. Backing up with

dd if=/dev/da0 iseek=1 bs=512 count=1 of=/tmp/sector1.dd

and then transfering to some other host solved the things.

It seems that hfaxd binds to default listening socket on FreeBSD that defaults to ipv6 only. This prevents ipv4 clients to bind to it and sending faxses is not possible. Setting sysctl net.inet6.ip6.v6only=0 does not help. The only way to allow ipv4 clients is to patch with multiple -l -i pairs of socket binding.

Sneak preview of the Karmic Ubuntu shows quite a good performance with a GMA500 graphics when using PPA repository and binary drivers provided from Intel. Since display is 11'' big one does not really need specialized window manager for netbooks. But anyway is a way to go because two additional lines can be seized with dumb window manager. But this requires additional learning that can be of value after get used to it. Unfortunately I am not well acquainted to them. After initial testing I seems that this laptop can be recommended for low power usage and typing under Linux. There is a problem with OpenGL not working after suspend. Right now this can be a major drawback of this laptop.
