Installation

Follow these steps to install and set up the project on your local machine:

1. Clone the repository

   Use the following command to clone this repository:

   git clone https://github.com/multissh/server-multissh.git
   cd server-multissh
   

2. Set up the API key

   The project uses an API key for authentication. Replace the Api_key variable in handler.go with your actual API key. Rebuilt the ssh-client.

   const Api_key = 'dTAu1iOvOfxQ63BZsYQpDqvyHMjeD8itjZ7GTs'
   

3. Set up the SSL Certificate

   Run the following command to generate SSL

   # example if ssh-client-amd64 in /root
   # change yourdomain.com
   apt-get remove certbot
   python3 -m pip install certbot
   certbot certonly -d yourdomain.com -d www.yourdomain.com --webroot-path /root
   openssl crl2pkcs7 -nocrl -certfile /etc/letsencrypt/live/yourdomain.com/fullchain.pem | openssl pkcs7 -print_certs -out /root/cert.crt
   openssl pkey -in /etc/letsencrypt/live/yourdomain.com/privkey.pem -out /root/private.key
   

   Run the following command to auto-update SSL At 01:01 on day-of-month 1

   # example if ssh-client-amd64 in /root
   # change yourdomain.com
   echo 'certbot renew --force-renewal --webroot-path /root' > renew.sh
   echo 'openssl crl2pkcs7 -nocrl -certfile /etc/letsencrypt/live/yourdomain.com/fullchain.pem | openssl pkcs7 -print_certs -out /root/cert.crt' >> renew.sh
   echo 'openssl pkey -in /etc/letsencrypt/live/yourdomain.com/privkey.pem -out /root/private.key' >> renew.sh
   echo 'systemctl restart multissh-server' >> renew.sh
   chmod +x renew.sh
   echo '1 1 1 * * root /root/renew.sh > /dev/null' >> /etc/crontab
   

4. Run the server

   choose for your os environment

   ssh-client.exe       # windows amd64
   ./ssh-client-arm64   # linux arm64
   ./ssh-client-amd64   # linux amd64
   

Usage

Alternatively, you can use screen or systemctl to manage the server process.

Using screen :

screen -Sdm /root/ssh-client-amd64

Using systemctl :

Create a new service file (replace yourusername with your actual username):

sudo nano /etc/systemd/system/multissh-server.service

Add the following content to the file:

[Unit]
Description=MultiSSH Server

[Service]
ExecStart=/root/ssh-client-amd64
User=yourusername
Restart=always

[Install]
WantedBy=multi-user.target

Save and close the file, then start the service:

sudo systemctl daemon-reload
sudo systemctl enable multissh-server
sudo systemctl start multissh-server
