-Login to the login-nodes is mediated by a jump node: Access is done with direct login (ssh) to "''mogon''". This name implements a 'Round-Robin-DNS' login to both login nodes of MOGON I''mil01.zdv.uni-mainz.de'' and ''mil02.zdv.uni-mainz.de''. If for some reason you want to login to a specific login node, you can use these names directly. (or if for some other reason one of the nodes is broken, and the DNS always gives you the wrong, broken one to connect to)+The latter link contains information for accessing MOGON with PuTTYMobaXterm and PowerShell.
  
-The login nodes of **MOGON II** are ''miil01.zdv.uni-mainz.de'' to ''miil03.zdv.uni-mainz.de''. Projects on MOGON I do not have access to MOGON II automatically. You have to apply for MOGON and MOGON II separatelyOnly password-less login is available.+The service nodes of MOGON are listed below.

 ==== Generating a new SSH-Key using Linux or macOS ==== ==== Generating a new SSH-Key using Linux or macOS ====
-In case you not yet have an SSH-Key pair on your computer, you can use the following command to create a new pair: 
- 
-<code bash>ssh-keygen -t rsa -b 4096 -C "HPCGATE,HPCLOGIN"</code> 
- 
-This generates a new private/public ''RSA'' key pair with ''4096 bit'' key size. \\ {{fa>hand-o-right?fw}} Please note: The part ''-C "HPCGATE,HPCLOGIN"'' creates the mandatory comment, which can be pasted into the web form. {{fa>hand-o-left?fw}} \\ Then ''ssh-keygen'' asks for a name for the key.  
- 
-<code>Enter a file in which to save the key (/home/you/.ssh/id_rsa): [Press enter] </code> 
- 
-After that you have to specify a passphrase - {{fa>warning?fw}} **Do not** use an empty passphrase! {{fa>warning?fw}} 
- 
-<code bash>Enter passphrase (empty for no passphrase): [Type a passphrase] 
-Enter same passphrase again: [Type passphrase again] </code> 
- 
-In this case you deviate from the default names and you ought make your ''ssh-agent'' aware of it: 
-<code bash> 
-ssh-add ~/Path/To/Your/PrivateKey 
-</code> 
- 
-=== Modify existing SSH-Keys === 
-If you already have an SSH-Key pair, you can change the comment as follows, for example to add the ''HPCGATE,HPCLOGIN'' string if you have forgotten to append it: 
- 
-<code bash>  
-ssh-keygen -c -C "HPCGATE,HPCLOGIN" -f ~/Path/To/Your/PrivateKey 
-</code>
