What is SSH? What is SFTP?

SSH (Secure Shell Protocol) is a secure replacement for telnet. Like telnet, SSH can be used to connect to a remote host computer using an account name and password. The advantages of SSH over telnet are:

Documentation remote-access ssh unix SSH using Linux or Mac OS. You can use SSH to connect to your Raspberry Pi from a Linux computer, a Mac, or another.

  1. All information transmitted between your computer and the host is encrypted. This protects your password during login as well as information transmitted after logging in.
  2. If available, you can use a publicly published 'fingerprint' for a host's 'key' to verify the host's identity.

Make a Connection to a Remote Host

Mount your SD card on your computer. Create or copy a file called ssh in /boot. You can do it right after flashing Volumio, by creating it in the 'Boot' partition of your SD Card. So I figured if I could ssh using a MAC address I could just do an arp -a see the mac. Then log in get the information I need and dump it to a database then just continue down the loop until all the devices are done. I think there is a way to MAC telnet, but the davices have ssh as default. Any ideas would be helpful.

SSH Keys (optional) If you wish, you can setup an SSH Key, which will allow you to connect to SSH without needing to manually enter your password. If you'd like information on this process, feel free to check out the article below: Using SSH keys on your server Using SSH keys on your server; Add Terminal to the dock (optional). Shell Access (SSH) Mac OS X comes preinstalled with OpenSSH, the most popular implementation of the SSH protocol. The client can be run from the command-line and is simply called ssh.

Ssh Mac Manual
  1. Open Terminal in the Applications > Utilities folder.
  2. Type ssh account_name@host_name in the terminal window, where account_name is your account name on the host and host_name is the host's full Internet name. Press the Return key. If you are connecting to apollo.sfsu.edu or libra.sfsu.edu then replace account_name with your SFSU email account name and replace host_name with either apollo.sfsu.edu or libra.sfsu.edu. For example, Jane Doe, with SFSU email account janedoe, would connect to host libra.sfsu.edu by typing:ssh janedoe@libra.sfsu.edu then pressing the Return key.
  3. The first time you connect to a host you will see a message similar to:

    The authenticity of host 'libra.sfsu.edu (130.212.10.238)' can't be established.
    RSA key fingerprint is 57:fe:4b:78:94:1e:8c:3d:28:ce:67:40:85:fe:24:85.
    Are you sure you want to continue connecting (yes/no)?

    • Verify the host matches one of the following:
      • online.sfsu.edu - updated 11/25/08
        • 06:4e:57:ee:f5:c8:e7:c7:99:9a:e9:5f:95:88:53:a1
          xunil-novip-mafuh-moduc-tunuk-dulyb-symen-hebim-tacec-kypiz-nyxax
      • www.sfsu.edu - updated 11/25/08
        • 73:c2:09:ec:f5:8a:a2:cf:d8:4e:34:bd:24:1f:b3:66
          xepop-cigab-vokyd-tipyh-vadaf-sidez-cunat-sylol-befug-sikyf-rixex
        • a4:bd:6f:3c:61:5b:15:7b:da:ef:7f:1c:27:2a:8a:b2
          xonob-likem-tunyg-semon-nogeb-bukag-hucos-zyzyg-mecih-zuvoh-lexix
      • If the fingerprints do NOT match, click the Cancel button to cancel your connection. Submit a Service Request. Mismatched fingerprints might mean that your connection has been compromised.
      • If the fingerprints DO match, type yes then press the Return key. You will see a message similar to:

        Warning: Permanently added 'libra.sfsu.edu,130.212.10.238' (RSA) to the list of known hosts.

  4. Type your password when prompted then press the Return key.
  5. Use the resulting SSH session the same way you would use a telnet session.
  6. When you are finished exit your SSH session, close your terminal window, then close Terminal.

What if the Fingerprints Matched Originally but They Don't Now?

Using the SSH client built in to Mac OS X you will you get a message similar to the following:

Mac

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is 57:fe:4b:78:94:1e:8c:3d:28:ce:67:40:85:fe:24:85.
Please contact your system administrator.
Add correct host key in /Users/janedoe/.ssh/known_hosts to get rid of this message.
Offending key in /Users/janedoe/.ssh/known_hosts:1
RSA host key for libra.sfsu.edu has changed and you have requested strict checking.
Host key verification failed.

This either means that the host has a new key and the fingerprint has changed or that you are the victim of a man-in-the-middle exploit. In order to protect you, the Mac OS X SSH client will not let you complete the connection to this host until the old key is removed from your computer. If you determine that the host's key has been changed (see connection instructions for current keys), follow these steps to remove the old key:

  1. Open Terminal in the Applications > Utilities folder.
  2. Type open .ssh in the terminal window then press the Return key. This opens the .ssh folder which contains the file known_hosts.
  3. Drag known_hosts into the trash then close the .ssh folder.
  4. Close Terminal.

Deleting known_hosts removes all host keys from your computer so all hosts you connect to will be treated as though you are connecting to them for the first time.

SSH access on volumio

When SSH is activated on Volumio (see below how to) you can access your device using:

From Windows : Putty

From Linux : commande ssh from a terminal

From MacOs openssh

Once it is ready, use to log in:

  • user: volumio

  • password: volumio

Example (linux) : ssh volumio@192.168.1.54

Type Enter. It retruns:

Ssh Mac Manual Pdf

volumio@192.168.1.54's password:

Type volumio (password, case sensitive) and Enter

And here you are !

From here you can get a full access to your device.Some command requires Root privilèges. To do that use sudo with password volumio

example sudo nano /etc/samba/smb.conf

WARNING! You can damage your Volumio with sudo. Editing system files may prevent Volumio to be updated over the air (integrity check will fail).

How to enable SSH

For security reasons, SSH is disabled by default on all versions after 2.199 (except first boot). It can be however enabled very easily. See below!

First method: DEV UI (easy)

Ssh Settings Mac

Navigate to the DEV ui by pointing your browser to VOLUMIOIP/DEV or volumio.local/DEV . Find the SSH section, and click enable. From now on your SSH will be permanently enabled.

Note : You'll see no change when clicking on the button, but it will be ok.

Second method: file (more advanced)

Mount your SD card on your computer.

Create or copy a file called ssh in /boot . You can do it right after flashing Volumio, by creating it in the 'Boot' partition of your SD Card.
