مراحل ریست نمودن پسوورد یوزر ROOT در لینوکس

If you forgot your root password for your debian server use the following procedure to reset.

Boot to the GRUB menu. Then, press <e> (for edit) before Linux has a chance to boot.

Using your keyboard arrow keys, move the cursor down a line or so, and press <e> (for edit) again, you should now be on the kernel line, and press <End> to go out to the very end of that line. Now hit the spacebar once, if necessary, to add a space, and then add one of the folllowing:




Then press <Enter>, and you're back at the kernel line, press <b> (for boot) and the computer will proceed to boot to a root prompt.

At this point, the root file system is still mounted read-only, so enter the following command:

mount -n -o remount,rw /

Then type:


Enter your new password. Retype if asked to confirm.

Then restart the machine by typing:


Now you should be able to login with your new root password as required.

نحوه تنظیم Static Route بصورت ثابت بر روی سرور لینوکس

To keep the Static Route persistent on Linux or you want to add the route entries to the network

 script files (not using the route command) then all you need to do is to edit the file


and the static routes in the following format:

up route add [-net|-host] <host/net>/<mask> gw <host/IP> dev <Interface>


up route add -net gw dev eth1

And the file will like the following

sudo cat /etc/network/interfaces

The output should show something like this

sudo cat /etc/network/interfaces

The output should show something like this

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0 eth1

iface eth0 inet static
# dns-* options are implemented by the resolvconf package, if installed

iface eth1 inet static

# static route
up route add -net gw dev eth1

The above has 2 Ethernet interfaces and the static route is added to the interface eth1.

For the change to /etc/network/interface to take effect. please restart the "networking" service as follows:

sudo /etc/init.d/networking restart

NOTE: If you added the route already using the "route" then there is no need to restart the networking service because, the next time server is restarted this takes effect.
