Server Details

Host gamma3
  HostName 10.153.170.43
  User ephysXX
  Port 22

Replace ephysXX with your username (e.g., ephys07).

macOS — Terminal

1) Generate SSH key

ssh-keygen -t ed25519 -C "your_email@domain.com"

Press Enter to accept the default path ~/.ssh/id_ed25519. Optionally set a passphrase.

2) Configure SSH

nano ~/.ssh/config

Host gamma3
  HostName 10.153.170.43
  User ephysXX
  Port 22

Save with Ctrl+O, Enter, then exit with Ctrl+X.

3) Test first login (password)

ssh gamma3

Use your temporary password (provided separately). Type exit to log out.

4) Install your public key

Preferred (automatic):

ssh-copy-id gamma3

Manual (if needed):

cat ~/.ssh/id_ed25519.pub
ssh gamma3
mkdir -p ~/.ssh && chmod 700 ~/.ssh
echo "<paste-your-key-here>" >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys

5) Verify write access

ssh gamma3
cd /storage2/arash/teaching/neuropy
cd <your_firstname>
touch test.txt
ls -l
rm test.txt

Linux — Terminal

1) Generate SSH key

ssh-keygen -t ed25519 -C "your_email@domain.com"

2) Configure SSH

nano ~/.ssh/config

Host gamma3
  HostName 10.153.170.43
  User ephysXX
  Port 22

3) Test first login (password)

ssh gamma3

4) Install your public key

ssh-copy-id gamma3

If ssh-copy-id is missing, use the manual method shown on the macOS tab — it's identical on Linux.

5) Verify write access

ssh gamma3
cd /storage2/arash/teaching/neuropy
cd <your_firstname>
touch test.txt
ls -l
rm test.txt

Windows — PowerShell (or Git Bash)

1) Generate SSH key

ssh-keygen -t ed25519 -C "your_email@domain.com"

Default location is C:\Users\<You>\.ssh\id_ed25519. Optionally set a passphrase.

2) Configure SSH

Create (or edit) the file C:\Users\<You>\.ssh\config with:

Host gamma3
  HostName 10.153.170.43
  User ephysXX
  Port 22

3) Test first login (password)

ssh gamma3

4) Install your public key

Show your public key locally:

type $env:USERPROFILE\.ssh\id_ed25519.pub

Copy the full line that starts with ssh-ed25519, then on the server:

ssh gamma3
mkdir -p ~/.ssh && chmod 700 ~/.ssh
nano ~/.ssh/authorized_keys  # paste your key, save
chmod 600 ~/.ssh/authorized_keys

If you prefer PuTTY: generate an Ed25519 key with PuTTYgen, save the .ppk, and paste the public key text into authorized_keys. In PuTTY, save a session named gamma3 with HostName 10.153.170.43 and your username.

5) Verify write access

ssh gamma3
cd /storage2/arash/teaching/neuropy
cd <your_firstname>
touch test.txt
ls -l
rm test.txt
