It is recommended that SSH Server should be used from Termux instead of using it inside the Linux. Using SSH Server from Termux gives you control of both your device and your Linux OS. We are providing you both the methods below:

## SSH from Termux:

You can follow [this](https://glow.li/technology/2015/11/06/run-an-ssh-server-on-your-android-with-termux/) link to get to know the process of using SSH from Termux. This tutorial is provided officially by one of the Termux developers.

## SSH from Linux:

Since Linux is executed by using PRoot, it cannot override the default configurations of the Android connectivity so the port number needs to be changed. Follow the below steps to use SSH from Termux:

Install **openSSH** inside Linux. Choose the command for your distro accordingly from the given list:

### Ubuntu 19

```
apt install openssh-server nano -y
```

### Ubuntu 18

```
apt install openssh-server nano -y
```

### Kali Security OS

```
apt install openssh-server nano -y
```

### Debian

```
apt install openssh-server nano -y
```

### Manjaro

```
pacman -S openssh nano --noconfim
```

### Arch

```
pacman -S openssh nano --noconfim
```

### Fedora

```
dnf install -y openssh-server nano
```

### Alpine

```
apk add openssh-server nano
```

### Void

```
xbps-install openssh nano
```

* Once OpenSSH server is installed in your Linux system, we need to modify some things to make it accessible in network escaping Android limitations. Now do:

```
nano /etc/ssh/sshd_config 
```

* Find and change the line `#Port 22` to `Port 2222` 
* Find the line `#PermitRootLogin prohibit-password`  or `#PermitRootLogin yes`  and change it to `PermitRootLogin yes` . If it is already `PermitRootLogin yes` then you do not need to change anything.
* Now when you are done with all the above steps press **CTRL+X** and then type **Y** and then press **Enter**
* Now do `ssh-keygen -A` and then `ssh-keygen` 
* Now we need to set password first. To set password type `passwd` and set any password.  
* Once this process is complete just run `/usr/sbin/sshd` to start the SSH server.
* Now just type `ip a`  and copy the IP Address of `wlan` and to connect to SSH Server. 
* To connect to SSH server type `ssh root@localhost -p 2222` and use the password to connect to the server.
