x2go – possible replacement to VNC

If you are accessing you Linux machine from VNC then you can try x2go.

Pretty straight forward installation, with packages available for both Ubuntu and Fedora and most other common distros as well. Just install, change one line ( visit the link above) and you are done. Neat, I must say.

Do try it when you feel the need to do something new.

Raspberry Pi automate certain tasks – script example

Now, if you have followed these :

fetchmail

ssmtp

Then you already have a working system for sending and receiving mail. Now, you can set the mda in the fetmailrc to a script which can do few things for you. The script below will get a page and mail it to you, if you have the subject as “get” and send “wake on LAN” to desired PC if you have subject as “wol”. Cool 🙂

Original idea from here.

Here is the script:

#!/bin/bash

expectedFrom=""
expectedFrom2=""
homePC="MAC Here"

mailHelp() {
	sendMail $1 "Help - Possible Commands" "Help"
}

sendMail() {
	echo "To: "$1 > $tmpMail
	echo "From: From address here" >> $tmpMail
	echo "Subject: "$2 >> $tmpMail
	echo "Content-Type: text/html" >> $tmpMail
	echo "" >> $tmpMail
	echo $3 >> $tmpMail
	cat $tempMail >> $tmpMail
	cat $tmpMail|/usr/sbin/ssmtp  $1
}
#here we start the actual processing

rightSender=0
sender=""
tmpFile=/tmp/mailtemp
tmpMail="/var/tmp/mailtxt.txt"
tempMail="/tmp/tosend.txt"
>$tempMail
>$tmpFile
>$tmpMail

#Write the mail to tmpFile
while read line
do
	echo $line >> $tmpFile
done

grep "From:" $tmpFile | grep $expectedFrom > /dev/null
if [ $? -eq 0 ]; then
	rightSender=1
	sender=$expectedFrom
fi

grep "From:" $tmpFile | grep $expectedFrom2 > /dev/null
if [ $? -eq 0 ]; then
	rightSender=1
	sender=$expectedFrom2
fi

if [ $rightSender -eq 1 ]; then
	task=`grep "Subject:" $tmpFile`
	task=${task:9}
	task=`echo $task | tr [:upper:] [:lower:]`

	echo $task | grep "help" > /dev/null
	if [ $? -eq 0 ]; then
		mailHelp $sender
		exit
	fi
fi
while read line
do
	if [[ $line =~ ^$|^Content*:*|^charset=*|^--=* ]]; then
		continue;
	fi
	echo "LINE :: $line"
	case $task in
		get)
			cmd="wget -o /dev/null -O - $line"
		;;
		wol)
			cmd="sudo etherwake $$line"
		;;
		*)
			cmd="$line"
		;;
	esac
	eval $cmd >> $tempMail
done < <( sed '1,/^$/ d' $tmpFile|sed '/^--$/,$ d')
sendMail $sender "Output result of command $task" "Happy Hacking"

rm $tmpFile
rm $tmpMail
rm $tempMail

nautilis fork ( File manager ) with tree view in sidebar.

Was searching for this for sometime now, finally found it.

sudo yum install nemo
sudo yum list nemo*

First just install nemo. Configure nemo not to interfere with default desktop and also make it default handler. So, here are the settings that would do it.

gconftool-2 --set  /desktop/gnome/applications/component_viewer/exec --type 'string' 'nemo "%s"'
gconftool-2 --set  /desktop/gnome/url-handlers/trash/command --type 'string' 'nemo "%s"'
gsettings set org.nemo.desktop show-desktop-icons false

Now, if you need more functionality in file manager then check the list of nemo packages from the output of second command of yum. It has plugins like file preview and so on. Install and enjoy.
