Automatic website backup without SSH enabled over FTP

Last time I backed up my website with rsync and ssh, but on my new host they disabled SSH. Rsync does not work over ftp. I do not want to do incremental backups with delta files like is done with rdiff-backup or duplicity. I need to have an exact mirror of my site. But remember that your sql databases won’t be backed up.

Curlftpfs is the key! In this tutorial I will show you how to backup from one server to a backup location which can be your hard drive, another web host, dropbox folder, Box.net via webdav, etc.

Download curlftpfs, rsync and ncftp:
sudo apt-get install curlftpfs ncftp rsync

make directories to mount your ftp server:
sudo mkdir /media/hydtechblog
sudo mkdir /media/hydtechbackupserver

edit fstab to mount the ftp servers using curlftpfs:
sudo gedit /etc/fstab

add the lines and modify them according to your server:
curlftpfs#username:password@hydtechblog.com /media/hydtechblog fuse rw,allow_other,uid=root 0 0
curlftpfs#username:password@hydtechbackupserver /media/hydtechbackupserver fuse rw,allow_other,uid=root 0 0

One thing to remember is that these two will not mount automatically because when the computer restarts, the fstab is done while you are not connected to the network. To fix this we can just add the mount commands in our crontab.

Edit crontab:
sudo crontab -e
enter the following lines and modify accordingly:
00 09 * * * mount /media/hydtechblog
00 09 * * * mount /media/hydtechbackup
01 09 * * * rsync -avz –rsync-path=/usr/bin/rsync /media/hydtechblog/public_html /media/hydtechbackup/public_html

ctrl + o to write and ctrl + x to save

This will tell cron to mount the folders at 9:00 am and start rsync at 9:01 am. You can replace the backup location to another folder on your hard drive or your dropbox or ubuntu one folder. You can also mount box.net with webdav and use this method.

For encrypted incremental backups checkout duplicity, it also works with webdav and ftp.

How to make the Broadcom 4312 Wireless driver work in BackTrack 4 on the Lenovo S10

This guide is adapted from Kazalku’s guide on remote exploit forums. Thanks Kazalku.

Download this driver and transfer it with a USB or boot up into another OS on your multiboot and save it in the BT root folder from here.

Untar it:

tar -xvzf hybrid-portsrc-x86_32-v5_10_91_9-3.tar.gz

makefile:
make -C /lib/modules/`uname -r`/build M=`pwd`

Insert the modules:
modprobe ieee80211_crypt_tkip
insmod wl.ko

Now you should have the network Claimed. you can check by:
lshw -C network

Bring it up:
ifconfig eth1 up

To load the module upon boot:

cp wl.ko /lib/modules/`uname -r`/kernel/net/wireless
depmod -a
modprobe wl

Load the module at every startup:
kate /etc/modules

add the following and close the text editor:
ieee80211_crypt_tkip
wl

Load NetworkManager and Configure KnetworkManager:
Type NetworkManager in a konsole and configure the wireless at the bottom right.

Delete the files you created in the root folder now that you dont need them.

Loud beeps from speaker in Lenovo S10

The lenovo S series netbooks can get pretty annoying with the speaker beeping all the time. To disable the speaker beep while plugging and removing the charger, you can change the setting in the BIOS. If there is no option, you must upgrade the BIOS.

Other annoying beep sound when I shut down my Ubuntu. To get rid of this I blacklisted my pc speaker:

gedit /etc/modprobe.d/blacklist

add line
blacklist pcspkr

Save and reboot.
