Nautilus Scripts

Started from here, talked about Send To feature ( this feature is famous in Ms. Windows — i think ) , i just realized that i have missed another simple thing !!
I found something in wiki and something in unleashed.

If you need Copy-To script :

#! /bin/bash
location=`zenity --file-selection --directory --title="Select a directory"`
for arg
do
if [ -e "$location"/"$arg" ];then
   zenity --question --title="Conflict While Copying" --text="File ""$location"/"$arg"" already exists. Would you like to replace it?"
   case "$?" in
      1  )  exit 1 ;;
      0  )  cp "$arg" "$location" ;;
   esac
else
   cp "$arg" "$location"
fi
done

If you need Move-To script :

#! /bin/bash
location=`zenity --file-selection --directory --title="Select a directory"`
for arg
do
if [ -e "$location"/"$arg" ];then
   zenity --question --title="Conflict While Moving" --text="File ""$location"/"$arg"" already exists. Would you like to replace it?"
   case "$?" in
      1  )  exit 1 ;;
      0  )  mv "$arg" "$location" ;;
   esac
else
   mv "$arg" "$location"
fi
done

just copy the script to your text editor and save it to
~/.gnome2/nautilus-scripts/

But, don’t forget one more thing;
your script must be executable by typing
sudo chmod a+x ~/.gnome2/nautilus-scripts
in Terminal.

You can get Send-To script here
Open your Nautilus and the scripts will be there when you right-click on something ( press reload button if you didn’t see any )

Done !!!

HP LaserJet 1020 on Hardy Heron

Frankly, i never know that this printer can’t directly work if we installed it in HH by using direct connection. Otherwise, i always use this printer through network and it works totally well.

When i looked at this problem in google… i was shocked that this issue is there and it was an error from the bundled driver of HH ( i am totally late in figure this out )
So….the solution was I have to replace the bundled driver !!

open Terminal
type sudo bash
apt-get install build-essential { install build-essential }
wget -c http://foo2zjs.rkkda.com/foo2zjs.tar.gz
{ to download the driver }
tar zxvf foo2zjs.tar.gz { extract the downloaded driver }
cd foo2zjs { change the working directory }
make { start to build the driver }
./getweb 1020 { get additional firmware }
make install { install the driver }
make install-hotplug { install hotplug }
make cups { restart cups }

done !! and Great Thanks to the resources

Simple anonymous ftp server

This time, i just wanted to create an ftp server to share some “read-only” files. If i put these files on a public samba shared, it will easily to be changed. It will not be good if you change a teaching schedule by yourself…not by the authorities.
Next example can be a master report file or master forms.

I just did :

install proftp :=> sudo apt-get install proftpd ucf
activate the anonymous section on the /etc/proftpd/proftpd.conf
restart proftp :=> sudo /etc/init.d/proftpd restart
Done !!
from web browser :=> ftp://servername/

When i did not activate the anonymous section on proftpd.conf, it seemed like we can open all home folders of that server ( of course this is BAD !! ) even the ftp asked for a password.

Missing fstab……

I slipped on my own script, my fstab erased…….
It only contain a line to mount CD-ROM….wakakakaka

After googling, i found this
By reading this article, i assumed that we have to know the UUID for each drive, especially for the / and swap ( for windows disk can be done later )

First, used blkid from terminal by typing sudo blkid
here is the output

/dev/sda1: UUID="2C28F09028F059F2" TYPE="ntfs"
/dev/sda5: UUID="2C82313F7F68F931" TYPE="ntfs"
/dev/sda6: TYPE="swap" UUID="f2ea4d4c-ef3f-49dd-9f4a-ea140e93c69e"
/dev/sda7: UUID="ced3011b-4675-4790-8065-d8e0601f6bf1" TYPE="ext3"

I just have to copy / and swap UUID and paste to my (new)fstab,
after some editing, it looks like :

/dev/scd0       /media/cdrom0   udf,iso9660 user,noauto,exec,utf8 0       0
//192.168.1.100/shared /media/x cifs rw,uid=root,gid=root,file_mode=0777,dir_mode=0777,noperm 0 0
UUID=ced3011b-4675-4790-8065-d8e0601f6bf1    /    ext3    relatime,errors=remount-ro    0    1
UUID=f2ea4d4c-ef3f-49dd-9f4a-ea140e93c69e    none    swap    sw    0    0   

After reboot, my system is back to normal
( I applied this to Hardy Heron, Intrepid Ibex and Mint Elyssa )
