View source for HowTo: Configure SSH2 access to the Admin Console

= Server - Admin Console Authorized Keys =
* To allow SSH2 access to the Admin Console a public key needs to be added to the authorized_keys file.
* SSH2 authentication in dCache works very similar to the standard SSH2 service.
* SSH2 authorized_keys file in dCache is found in: '''/etc/dcache/admin/authorized_keys2'''
:Please notice that in dCache is called '''''authorized_keys2''''' and not authorized_keys (which historically corresponds to SSH1 access to the dCache Admin Console)
* Example of content of '''/etc/dcache/admin/authorized_keys2''':

 ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDIODhZQPz/sxK44pTdOaCVWXM2qZPJ1Zz/xOHt31LKEC/seWf1fzy0YuC9Wu++eATtKXtv2fIryj9cFOhijXmAQtYHfhNCbBA

= Client - Private & Public Keys =
* In order to access to the Admin Console, SSH Keys must be generated.
* Use '''''ssh-keygen''''' in order to generate the public (id_rsa.pub) and the private (id_rsa) SSH Keys. For instance:

 user@pw-mcaubet:~$ ssh-keygen 
 Generating public/private rsa key pair.
 Enter file in which to save the key (/home/user/.ssh/id_rsa): 
 Enter passphrase (empty for no passphrase): 
 Enter same passphrase again: 
 Your identification has been saved in /home/user/.ssh/id_rsa.
 Your public key has been saved in /home/user/.ssh/id_rsa.pub.
 The key fingerprint is:
 1d:60:95:2f:73:94:b8:5b:d6:8c:2d:d4:d2:ea:b6:de user@pw-mcaubet
 The key's randomart image is:
 +---[RSA 2048]----+
 |        o..o +   |
 |       . .o = o  |
 |          .= B   |
 |         .+.O +  |
 |        S .O .   |
 |          . o    |
 |           . .   |
 |            ..   |
 |           .. E  |
 +-----------------+
* Add the generated '''id_rsa.pub''' to the '''/etc/dcache/admin/authorized_keys2''' in the dCache server (see '''[[HowTo:_Configure_SSH2_access_to_the_Admin_Console#Server - Admin Console Authorized Keys | Server - Admin Console Authorized Keys]]''')
