<h1>SSH</h1>
|
|
|
|
<h2> What is "SSH"!?</h2>
|
|
<br>Are you searching for a program for executing commands on a machine remotely or simply logging into a remote machine?
|
|
<br>Are you searching a program that provide you secure encryption communications between two host?
|
|
<br> I have the solution, SSH.
|
|
<br> SSH connects and logs you into a specified hostname, where the user have only to prove his identity to the remote machine.
|
|
<br> Briefly The ssh command provides a secure connection between two hosts over a insecure network.
|
|
|
|
<h3> Example of using ssh</h3>
|
|
|
|
-Logging to a remote server(to login in a remote server from local host)
|
|
<pre>
|
|
|
|
localhost:[~]> ssh username@remote-server
|
|
username@remote-server password:
|
|
remote-server:[~]>
|
|
|
|
</pre>
|
|
<br>
|
|
-Logging out from remote server(you can do easily "command+d")
|
|
|
|
<pre>
|
|
|
|
remote-server:[~]>exit
|
|
logout
|
|
Connection to remote-server closed.
|
|
localhost:[~]>
|
|
|
|
|
|
</pre>
|
|
|
|
<br>
|
|
-Running remote from local host
|
|
|
|
<pre>
|
|
|
|
localhost:[~]> ssh user@remote-host "ls test"
|
|
online-backup.dat
|
|
oracle-storage.bat
|
|
unix-dedicated-server.txt
|
|
|
|
</pre>
|
|
|
|
<br>
|
|
-Debugging ssh client(to debug and find the exact error without connection to the remote host)
|
|
|
|
<pre>
|
|
ssh -v user@remote-host
|
|
OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008
|
|
debug1: Reading configuration data /etc/ssh/ssh_config
|
|
debug1: Applying options for *
|
|
debug1: Connecting to remote-host [172.22.200.140] port 22.
|
|
debug1: Connection established.
|
|
debug1: identity file /home/user/.ssh/identity type -1
|
|
debug1: identity file /home/user/.ssh/id_rsa type -1
|
|
debug1: identity file /home/user/.ssh/id_dsa type 2
|
|
debug1: loaded 3 keys
|
|
..........
|
|
|
|
</pre>
|
|
|
|
<br>
|
|
-Copying files between remote host and local
|
|
|
|
<br>
|
|
from remote
|
|
<pre>
|
|
|
|
scp user@remote-host:/usr/local/bin/add.sh
|
|
</pre>
|
|
|
|
<br>
|
|
from local
|
|
|
|
<pre>
|
|
scp filename user@remote-host:/var/tmp/
|
|
</pre>
|
|
|
|
<p>Then, you can now connect and use svn like a programmer</p>
