Set up

Set up environment

  • Open a terminal: You need to know about these commands: ls , cd folder, cd .., ctrl+d
  • Open your editor: Atom or your favorite plain text editor.

How to connect to servers

  • encrypted key files: how to create your own keys
  • password

Setup your credentials

Look for the eofe-key file. The standard location is inside the ~.ssh/ folder with tight permissions, so it is private and only your user has access to it. Copy the file to that location:

Create the folder if it doesn’t exists: mkdir -p ~/.ssh

Move the file to the location: mv PATH_TO_EOFE_KEY/eofe-key ~/.ssh/.

Check the file’s permission: ll ~/.ssh/eofe-key

The file’s permission should look like this (look at the left hand side, the rw part):

-rw-------@ 1 lpantano staff 1.7K May 23 10:32 /Users/lpantano/.ssh/eofe-key

If not, type this:

chmod 700 ~/.ssh/ chmod 600 ~/.ssh/eofe-key

Then add the following lines to this file ~/.ssh/config (Open it with Atom editor if you don’t have experience editing from the terminal). This file contains information on how to connect to different computers: like username, hostname …

Host mit
Hostname eofe5.mit.edu
User lpantano
IdentityFile ~/.ssh/eofe-key
UseKeychain yes

UseKeychain, only in OSX systems

change the username to yours

This will allow you to connect just by issuing ssh mit and if you are on:

  • mac OSX: you will be asked for the password once and it’ll save it until you restart your computer.
  • linux: things work the same way if you are on a graphic session, otherwise you need a bit more work, it is not that bad :). You can do the following to be asked by the password only once.
eval `ssh-agent`
ssh-add ~/.ssh/eofe-key

Type the password you gave during registration

Test your connection

Now is the time to try and connect:

ssh mit

You need to get this working to move forward

Create working folder at the mit server

mkdir pilm103

Group shared folders

Every group at PILM has a private and shared space folder:

ls /net/eofe-data004/mnt/pool/picower001/

You should see this:

[lpantano@eofe5:~]
|$ ls /net/eofe-data004/mnt/pool/picower001/
general  heimanlab  lhtsailab  littletonlab  surlab  tyelab  wilsonlab  xulab

inside your group folder, you have the following structure:

  • user1
  • user2
  • user3
  • lab_shared
    • user1
    • user2
    • user3
