| 1 | == Getting an account == |
| 2 | |
| 3 | First, you need to send an email to Chad Cantwell (email: chad [at] iomail.org) and request an account. |
| 4 | |
| 5 | == ssh configuration == |
| 6 | |
| 7 | You can add the following lines to `~/.ssh/config` on your local machine: |
| 8 | {{{ |
| 9 | #!sh |
| 10 | Host gp greenplanet gplogin1.ps.uci.edu gplogin2.ps.uci.edu |
| 11 | HostName gplogin1.ps.uci.edu |
| 12 | User YOURGREENPLANETUSERNAME |
| 13 | HostKeyAlias gplogin1.ps.uci.edu |
| 14 | HostbasedAuthentication no |
| 15 | }}} |
| 16 | and replace `YOURGREENPLANETUSERNAME` by your greenplanet username. |
| 17 | |
| 18 | Once this is done, you can ssh green planet by simply doing: |
| 19 | |
| 20 | {{{ |
| 21 | #!sh |
| 22 | ssh gp |
| 23 | }}} |
| 24 | |
| 25 | == Setting up the password-less ssh == |
| 26 | |
| 27 | Once you have the account, you can setup a public key authentification in order to avoid having to input your password for each run. |
| 28 | You need to have a SSH public/private key pair. If you do not, you can create a SSH public/private key pair by typing the following command and following the prompts (no passphrase necessary): |
| 29 | {{{ |
| 30 | #!sh |
| 31 | $your_localhost% ssh-keygen -t rsa |
| 32 | Generating public/private rsa key pair. |
| 33 | Enter file in which to save the key (/Users/username/.ssh/id_rsa):RETURN |
| 34 | Enter passphrase (empty for no passphrase):RETURN |
| 35 | Enter same passphrase again:RETURN |
| 36 | Your identification has been saved in /Users/username/.ssh/id_rsa. |
| 37 | Your public key has been saved in /Users/username/.ssh/id_rsa.pub. |
| 38 | }}} |
| 39 | |
| 40 | Two files were created: your private key `/Users/username/.ssh/id_rsa`, and the public key `/Users/username/.ssh/id_rsa.pub`. The private key is read-only and only for you, it is used to decrypt all correspondence encrypted with the public key. The contents of the public key need to be copied to `~/.ssh/authorized_keys` on your greenplanet account: |
| 41 | |
| 42 | {{{ |
| 43 | #!sh |
| 44 | $your_localhost%scp ~/.ssh/id_rsa.pub username@your_remosthost:~ |
| 45 | }}} |
| 46 | |
| 47 | Now on '''Greenplanet''', copy the content of id_rsa.pub: |
| 48 | |
| 49 | {{{ |
| 50 | #!sh |
| 51 | $your_remosthost%cat ~/id_rsa.pub >> ~/.ssh/authorized_keys |
| 52 | $your_remosthost%rm ~/id_rsa.pub |
| 53 | }}} |
