Mount remote machine file system on local machine through ssh

SSH (Secure Shell) is a network protocol that allows secure communication between two network devices. Normally, we use ssh to access Linux and Unix based system shell remotely. But we can also use ssh to mount remote machine file system on local machine. For that you need to install SSHFS packaged on your machine. SSHFS is a filesystem client based on the SSH File Transfer Protocol.
Install sshfs via YUM,

# yum install sshfs -y

 
Or install sshfs via APT,

# apt-get install sshfs
 
If you want to mount /root partition of 192.168.0.1 server then,
First create a mount point

# mkdir /mnt/root
 
Then run sshfs as,

# sshfs root@192.168.0.1:/root /mnt/root
 

How to extract a specific file From RPM Without installing:-

By mistake If u have deleted /sbin/poweroff file from system.
How to find the RPM has this /sbin/poweroff

# yum whatprovides /sbin/poweroff

systemd-sysvinit-10-2.fc14.1.

i686 contains /sbin/poweroff in Fedora 14.

Now, if you try to install that package using yum, we will get “Package systemd-sysvinit-10-2.fc14.1. i686 already installed and latest version”.

To restore /sbin/poweroff, all we need is systemd-sysvinit-10-2.fc14.1. i686.rpm and rpm2cpio, this is bundled with rpm-x.x.x…i386.rpm.

# rpm -ql rpm | grep rpm2cpio
/usr/bin/rpm2cpio

/usr/lib/rpm/rpm2cpio.sh

/usr/share/man/ja/man8/ rpm2cpio.8.gz

/usr/share/man/ko/man8/ rpm2cpio.8.gz

/usr/share/man/man8/rpm2cpio. 8.gz

/usr/share/man/pl/man8/ rpm2cpio.8.gz

/usr/share/man/ru/man8/ rpm2cpio.8.gz

# rpm2cpio systemd-sysvinit-10-2.fc14.1. i686.rpm | cpio -idmv

# cp sbin/poweroff /sbin/

Note: There is another way to install systemd-sysvinit-10-2.fc14.1. i686.rpm by forcefully installing it.

# rpm -ivh systemd-sysvinit-10-2.fc14.1. i686.rpm –force

How to restore the DELETED Files in Linux

After deleting a file from your computer, it goes straight into the Trash bin. If you want to get that file back then you can get it by restoring it from the Trash bin.

If you want to delete it permanently, delete it from the Trash bin. You can then run the following command to do the trick,

# rm-rf /home/USER/.local/share/Trash/info/*

# rm-rf /home/USER/.local/share/Trash/ files/*

Do you want to quickly serve a directory to your friends over the web or LAN? There are plenty of applications out there that let you do this, but in Linux all you really need is Python installed.

Do a
python -m SimpleHTTPServer
in the directory you wish to share, then access http://127.0.0.1:8000 in your browser.
