Meiga makes file sharing breeze

linuxmasters — Fri, 08 Apr 2011 07:17:12 +0000

Tired of writing scripts and configuring the smb.conf file to make folders sharable on the lan and accessible with other clients on windows network.

Just install Meiga on your linux desktop and use the regular browser to access the shared folders from the linuxBOX. E.g http://192.168.1.1/Songs/

On debian system just install apt-get install meiga,once done fire up the app and add the folder to share and done.

Multi-wan Script – Failover Linuxbox

linuxmasters — Tue, 17 Aug 2010 11:19:41 +0000

Created this small script that checks the given ip address for connectivity by pinging the same. if the ping response is RTO the default gateway is automatically changed to the next given supplied route/gateway and incase failover goes down it automatically again switches it back to the primary gateway/route.

Tweak the script as per your requirement and make it load at Linuxbox Startup.

while true
do
for ipaddress in `cat /etc/gateway1.txt`

#enter ISP Default gateway in the file above to check.
do
echo “Pinging Main Gateway”
ping -c 10 $ipaddress
if [ $? != 0 ]
then
echo “$ipaddress is down – MainLINK”
route del default
route add default gw IPADDRESS eth1
fi
sleep 30
echo “Pinging FailOVER Gateway”

ping -c 2 $ipaddress
if [ $? != 0 ]
then
echo “$ipaddress is down – FAILOVER”
route del default
route add default gw IPADDRESS eth1
fi

done
echo “Waiting 60 Seconds to recheck”
sleep 60

#change the sleep time as per requirement
done

Bubakup For System Recovery

linuxmasters — Sun, 13 Jun 2010 17:51:50 +0000

Bubackup just works out of the box, install the tool and make a ghost of the working OS and create a bootable working clone of the hard drive in seconds.…Incase the system fails to boot just boot the system from the loopback mounted image and restore the OS in a flash…

Nifty recovery tools for Sysadmins and newbies who occasionally loose their OS.

LTSP – UP and Running..

linuxmasters — Thu, 01 Apr 2010 06:40:08 +0000

Setup LTSP – Remote Boot PXE Enabled Thin Clients or PXE enabled PC/Laptops

We would first install the Required applications step by step and then configure them later.

1.Install the Regular Ubuntu Desktop Distro, I am using ubuntu 9.04 for this howto.
2.Once Installed, update the distro and install all the necessary updates.
3.Once Done Install NFS kernel Server via this Command : sudo apt-get install nfs-kernel-server
4.Install the DHCP SERVER on the same machine,make sure there is only one dhcp server running on the network else.it will cause a conflict.
5.Set a static ip to the machine via /etc/network/interfaces file – i am using 192.168.0.1 as SERVER ip for this HOWTO.
6.Now install the server module for LTSP running this command on terminal : – sudo apt-get install ltsp-server-standalone openssh-server ( this would install the LTSP Server and the openssh on the desktop.
7.Now Create your Thin Client environment on the server with this command: sudo ltsp-build-client
The First command installs the LTSP SERVER and the Second command installs the module that will provide/create the environment to run the remote disk less machines. ( Please be patient, the client module takes time to install as it fetches about 150 MB of files from the repos. )

Once the client installation is done run these 2 commands to create the ssh keys

sudo ltsp-update-sshkeys

sudo ltsp-update-image

Be sure to do it in that order.

We are now done with the installation. now comes the configuration part.

Open the /etc/default/tftpd-hpa and edit first line Run_Daemon to “Yes” in place of NO.Save and Exit.
Now Open the /etc/ltsp/dhcpd.conf and change some values to the file as below.uncomment value next-server and put the server ip infromt of it ( next-server 192.168.0.1; )
add these two values below that :
allow booting;
allow bootp;
now go to the last line of the dhcpd.conf and it has a default value : filename ( ”/ltsp/i386/nbi.img”; ) change that to ( filename “pxelinux.0″; )
Once done save and exit and restart the dhcp server /etc/init.d/dhcp3-server restart
Once done now u can just Boot the diskless workstations and it should aautomatically find the dhcp server get an IP address and load the Remote OS. and Login.
