SSH Without a Password

The following steps can be used to ssh from one system to another without specifying a password.

Notes:

• The system from which the ssh session is started via the ssh command is the client.
• The system that the ssh session connects to is the server.
• These steps seem to work on systems running OpenSSH.
• The steps assume that a DSA key is being used. To use a RSA key substitute 'rsa' for 'dsa'.
• The steps assume that you are using a Bourne-like shell (sh, ksh or bash)
• Some of this information came from:
  http://www.der-keiler.de/Mailing-Lists/securityfocus/Secure_Shell/2002-12/0083.html

Steps:

1. On the client run the following commands:
   

   $ mkdir -p $HOME/.ssh
   $ chmod 0700 $HOME/.ssh
   $ ssh-keygen -t dsa -f $HOME/.ssh/id_dsa -P ''
   

   This should result in two files, $HOME/.ssh/id_dsa (private key) and $HOME/.ssh/id_dsa.pub (public key).
2. Copy $HOME/.ssh/id_dsa.pub to the server.
3. On the server run the following commands:
   

   $ cat id_dsa.pub >> $HOME/.ssh/authorized_keys2
   $ chmod 0600 $HOME/.ssh/authorized_keys2
   

   Depending on the version of OpenSSH the following commands may also be required:

   $ cat id_dsa.pub >> $HOME/.ssh/authorized_keys
   $ chmod 0600 $HOME/.ssh/authorized_keys
   

   An alternative is to create a link from authorized_keys2 to authorized_keys:

   $ cd $HOME/.ssh && ln -s authorized_keys2 authorized_keys
   

4. On the client test the results by ssh'ing to the server:
   

   $ ssh -i $HOME/.ssh/id_dsa server
   

5. (Optional) Add the following $HOME/.ssh/config on the client:
   

   Host server
            IdentityFile ~/.ssh/id_dsa
   

   This allows ssh access to the server without having to specify the path to the id_dsa file as an argument to ssh each time.

To turn off autoindent when you paste code, there's a special "paste" mode.

Type

:set paste

Then paste your code. Note that the text in the tooltip now says -- INSERT (paste) --.

After you pasted your code, turn off the paste-mode, so that auto-indenting when you type works correctly again.

:set nopaste

Put the following in your vimrc (change  to whatever key you want):
set pastetoggle=

Perl programming: system() cmd

Link ref:

Executing Commands Without Shell Escape

Comparing values in perl

String matching: 

Problem:

You need to use a user's input as part of a command, but you don't want to allow the user to make the shell run other commands or look at other files. If you just blindly call the system function or backticks on a single string containing a command line, the shell might be used to run the command. This would be unsafe.

Solution:
Unlike its single-argument version, the list form of the system function is safe from shell escapes. When the command's arguments involve user input from a form, never use this:

system("command $input @files"); # UNSAFE

Write it this way instead:

system("command", $input, @files); # safer
