restore JFS filesystem under Ubuntu

today, a 5 disk SATA raid5 array misteriously went to 'beeping mode', it was unable to mount the JFS partition, however the ext3 root partition worked (thank God!) so we've needed to do the following:


apt-get install jfsutils
fsck.jfs -a -f /dev/sda2 -j /dev/sda2

Resume a download with wget

wget -c http://the-failed-download-s.url

Change locale on Ubuntu to make MC usable with a non utf-8 capable terminal

I like to use OpenSSH for Windows on my XP box, but unfortunately it does not understand utf-8. Ubuntu, however forces utf-8.


balint@s-xxx:~$ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

All we need to do is to remove the '.UTF-8' from all listings, by inserting the following lines into our .bashrc (or the configuration file of the shell we use):


export LANG=en_US
export LC_ALL=en_US

Assign fix IP to an ethernet interface on Ubuntu

Edit /etc/network/interfaces, and do it like this below: Make sure, you have all interfaces listed and automatically started:


auto lo eth0 eth1
iface lo inet loopback

First uncomment the DHCP, if it was active for eth0:


# The primary network interface
#auto eth0
#iface eth0 inet dhcp

Now you can enter the fixed values for eth0:


#custom
iface eth0 inet static
address 10.1.1.233
netmask 255.255.255.0
network 10.1.1.0
broadcast 10.1.1.255
gateway 10.1.1.254

If you have more interfaces, type all in as abowe.


iface eth1 inet static
        address 80.xx.xx.xx
        netmask 255.255.255.0
        broadcast 80.xx.xx.254
        network 80.xx.xx.0
