How can I work with command line on synology? [closed]

Question

How do I access the command line interface on a Synology NAS.

Specifically, I am trying to access the command line on a Synology DS1520+, running DSM 7.1, so I can enter the command: sudo shutdown -h, so I can power down the NAS remotely.

I am pretty sure I should use SSH and unix/linux style commands.

Answer 1

You can use your favourite telnet (not recommended) or ssh (recommended) application to connect to your Synology box and use it as a terminal.

1. Enable the command line interface (CLI) from the Network Services
2. Define the protocol and the user and make sure the user has password set
3. Access the CLI

Answer 2

I use GateOne from the synocommunity.

Go into settings in Package Center and add http://packages.synocommunity.com/ as a package source. Then you should be able to add it easily via Package Center.

currently it's broken with DSM 6, but they're working on it – Casualty

link --> "Bad Request - The browser (or proxy) sent a request that this server could not understand." (and by https:443 too); Btw, v20151116-6 last. EOL? – Intake

That one (I tried the latest version 20171125-8 on offer) still depends on Python 2.7, which has reached its end of support in January 2020. – Shiverick

GateOne is a generic SSH client with a web user interface; to connect to Synology itself, it also goes through SSH. The nice thing is that you can also connect to any other host through it, but I was specificially looking for terminal acccess to troubleshoot SSH problems, where GateOne is of no use, unfortunately. – Shiverick

Answer 3

The current windows 10 (Version 1803 (OS Build 17134.1)) has SSH built in. With that, just enable SSH from the Control Panel, Terminal & SNMP, be sure you are using an account in the Administrator's group, and you're all set.

Launch Powershell or CMD, enter ssh yourAccountName@diskstation

The first time it will cache off your certificate.

Answer 4

for my example:

Windows XP ---> Synology:DS218+

• Step1:
      > DNS: Control Panel (控制台)
           > Terminal & SNMP(終端機 & SNMP)

• Step2:
      Enable Telnet service (啟動 Telnet 功能)
      or Enable SSH Service (啟動 SSH 功能)
  
  
  
  
  
  

• Step3: Launch the terminal on Windows (or via executing

      cmd

  to launch the terminal)
  
  
  
  

• Step4: type: telnet your_nas_ip_or_domain_name, like below

      telnet 192.168.1.104

• Step5:
  demo a terminal application, like compiling the Java code

    Fzz login: tsungjung411

    Password:

    # shows the current working directory (顯示目前的工作目錄)
    $ pwd
    /var/services/homes/tsungjung411


    # edit a Java file (via vi), then compile and run it 
    # (透過 vi 編輯 Java 檔案，然後編譯和執行)
    $ vi Main.java

    # show the file content (顯示檔案內容)
    $ cat Main.java
    public class Main {
        public static void main(String [] args) {
            System.out.println("hello, World!");
        }
    }

    # compiles the Java file (編譯 Java 檔案)
    javac Main.java

    # executes the Java file (執行 Java 檔案)
    $ java Main
    hello, World!

    # shows the file list (顯示檔案清單)
    $ ls
    CloudStation  Main.class  Main.java  www

    # shows the JRE version on this Synology Disk Station
    $ java -version
    openjdk version "1.8.0_151"
    OpenJDK Runtime Environment (IcedTea 3.6.0) (linux-gnu build 1.8.0_151-b12)
    OpenJDK 64-Bit Server VM (build 25.151-b12, mixed mode)

---

• Step6:
  demo another terminal application, like running the Python code

    $ python
    Python 2.7.12 (default, Nov 10 2017, 20:30:30)
    [GCC 4.9.3 20150311 (prerelease)] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>>
    >>> import sys
    >>>
    >>> # shows the the python version
    >>> print(sys.version)
    2.7.12 (default, Nov 10 2017, 20:30:30)
    [GCC 4.9.3 20150311 (prerelease)]
    >>>
    >>> import os
    >>>
    >>> # shows the current working directory
    >>> print(os.getcwd())
    /volume1/homes/tsungjung411

    $ # launch Python 3
    $ python3
    Python 3.5.1 (default, Dec  9 2016, 00:20:03)
    [GCC 4.9.3 20150311 (prerelease)] on linux
    Type "help", "copyright", "credits" or "license" for more information.
    >>>

This was the clearest answer, which worked for me. Thank you very much. – Rema

Answer 5

I used Powershell under Windows 10 as suggested above, simply because it allows me to paste extremely long command lines that I have edited in another program.

Autochthon

Answer 6

On top of @Peter's answer above, I strongly suggest to install some additional packaging system - Entware seems to be good, stable, still maintained and working on the latest DSM 7.

https://github.com/Entware/Entware/wiki/Install-on-Synology-NAS

With this, you can then install additional packages as you are used to on any other common Linux distribution.
