 +At first you will get a username and a password for this wiki. To get access to the user server __aerocom-users.met.no__, you have to send us a ssh public key since password authentication is disabled for security reasons on the user server. You can connect to the user server via //**ssh**//, but also use //**scp**// and //**rsync**// for data transfers. 
 +For more details on AeroCom database, please read about [[https://wiki.met.no/aerocom/data_submission|data submission procedure]]. 
 + 
 +==== How to create a ssh key ==== 
 + 
 +=== Step 1: Check for SSH keys === 
 +First, we need to check for existing ssh keys on your computer. Open up Terminal and run: 
 +<code>$ cd ~/.ssh 
 +$ ls 
 +# Lists the files in your .ssh directory</code> 
 + 
 +Check the directory listing to see if you have a file named <key>id_rsa.pub </key>.  
 +If you don't, go to step 2. If you already have an existing keypair, skip to step 3. 
 + 
 +=== Step 2: Generate a new SSH key === 
 + 
 +To generate a new SSH key, enter the code below. We want the default settings so when asked to enter a file in which to save the key,  
 +just press enter. 
 +<code> $ ssh-keygen -t rsa -C "my comment" 
 +Generating public/private rsa key pair. 
 +... 
 +</code> 
 + 
 + 
 +Enter the path to the file that will hold the key: By default, the file name $HOME/.ssh/id_rsa, which represents an RSA v2 key,  
 +appears in parentheses. 
 + 
 +<code> Enter file in which to save the key (/home/user/.ssh/id_rsa): <return> </code> 
 + 
 +Enter a passphrase for using your key: The passphrase you enter will be used for encrypting your private key. A good passphrase should be alphanumeric having 10-30 character length. You can also use a null passphrase however this can cause a security loophole. 
 + 
 +<code>Enter passphrase (empty for no passphrase): <Type the passphrase> </code> 
 + 
 +Re-enter the passphrase to confirm it: Type your passphrase once again to confirm it. 
 + 
 +<code> 
 +Enter same passphrase again: <Type the passphrase> 
 +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: 
 +0b:fa:3c:b8:73:71:bf:58:57:eb:2a:2b:8c:2f:4e:37 user@myLocalHost 
 +</code> 
 + 
 +=== Step 3: Send your public key to jan.griesfeller@met.no and anna.benedictow@met.no === 
 + 
 +In the folder ~/.ssh you will find file(s) ending with .pub. Please send us the one you just created e.g. <key> id_rsa.pub</key>. **And no other file**
