setup and configure ssh jump server

2  admin November 7, 2024  Getting Started, Installation

What is an SSH Jump Server?

SSH Jump server, sometimes called  SSH Jump host or  SSH Bastion host, or SSH gateway is an intermediate server running the sshd daemon where all users would have to login via SSH first to access the remote server or target servers behind the gateway. The ssh jump server can be on a public-facing network while the target servers or the destination servers can be on a private network behind a firewall for better security.

How to install, setup & configure the Ezeelogin SSH Jump server on a Linux box? 

FREE 30-DAY TRIAL,  CONTACT OUR SUPPORT TEAM FOR FREE 24/6 INSTALLATION & DEMO 

We can guide you or install & configure Ezeelogin SSH Jump server software for you and give you a demo on how to use it at no extra charge.  Contact our 24/6 Support Desk to schedule your free or guided installation. Also, schedule a free introductory session to get to know on how to use the Ezeelogin Jump server solution effectively and ask your questions with our engineers.

Step 1: Log in to the portal and issue a free license for 30 days.

  • Log in to your customer portal and issue the 30-day trial license for the SSH jump server  IP of the server where you intend to install Ezeelogin SSH jump host software.
  • If you are unsure of what your jump server IP is, simply login to your SSH jump server and run the command:

root@gateway:~# wget -qO- https://ezeelogin.com/myip

or

root@gateway:~# curl ifconfig.me

Note: If your ssh jump server is behind a NAT in a private LAN behind a firewall, you can still install Ezeelogin Bastion host software. You just need to find your public IP by running the above command on your SSH gateway server and issuing the license for the public-facing IP.

For PHP version 8.1.x: https://downloads.ezeelogin.com/ezlogin_7.38.0_php81.bin
For PHP version 7.x (end of life): https://downloads.ezeelogin.com/ezlogin_7.36.0_php71.bin
For PHP version 5.6 to 7.0 (end of life): https://downloads.ezeelogin.com/ezlogin_7.27.6_php56-70.bin
For PHP version 5.3 to 5.5 (end of life): https://downloads.ezeelogin.com/ezlogin_7.10.0_php53-55.bin
NOTE: 7.36.0 is the last version that supports PHP versions 7.x, 7.27.6 is the last version that supports PHP versions from 5.6 to 7.0, and 7.10.0 is the last version that supports PHP versions from 5.3 to 5.5

Step 2: Install SSH jump server dependency packages. 

Most Linux OS ( Ubuntu 20,22 / Debian 10,11,12 / RHEL 7,8,9 / SUSE Linux 15 / AlmaLinux 8,9, Rocky Linux 8,9 ) are supported but supporting packages have to be installed manually. 

  •    Refer to the system requirement below:

Hardware Requirements

  • Minimum 2048 MB Ram.
  • Minimum 2 GHz processing power.
  • Virtual Server or Dedicated Server.
  • Minimum 75GB Disk space.

Software Requirements

  • OS Architecture (Ubuntu - 24, 22, 20, 18; Debian - 12, 11, 10; RockyLinux - 9, 8; AlmaLinux - 9, 8; RHEL - 9, 8; SUSE - 15, 14) , [x86_64 and aarch64]
  • Web server (apache, lighttpd, nginx etc.)
  • MySQL server (from version 5.5 to 8.0)/MariaDB ( from version 5.1 to 10.4) (For AWS RDS MySQL 5.6,5.7 & MariaDB 10.2)
  • PHP (from version 5.6.x and above,  upto <= php 8.2)
  • Ioncube loader version 10 and above for PHP
  • MySQLi extension for PHP
  • JSON extension for PHP
  • Curl extension for PHP
  • Posix extension for PHP
  • LDAP extension for PHP (for LDAP web panel authentication)
  • Nodejs version >=14.x.x
  • OpenSSL
  • Encryption & Hashing Algorithms.
NOTE: PHP SUPPORT  --->  7.36.0 is the last version that supports PHP versions 7.1 to 7.4
  • Ensure the following conditions are met on your ssh jump server.

1. The firewall on the jump server should allow outbound connection to license.ezeelogin.com on port 443 to fetch the license and download the software from downloads.ezeelogin.com 

root@gateway:~# telnet license2.ezeelogin.com 443 

Connected to license2.ezeelogin.com.

Escape character is ’^]’.

root@gateway:~# telnet license.ezeelogin.com 443 

Connected to license.ezeelogin.com.

Escape character is ’^]’.

root@gateway:~# telnet downloads.ezeelogin.com 80

Connected to downloads.ezeelogin.com.

Escape character is ’^]’.

2. Ensure SELinux is disabled on the jump server. The command #sestatus will show if it’s active or not. If it is not installed, then it's fine. Refer to Disable Selinux to disable it.

root@gateway:~# sestatus

SELinux status: disabled

3. Ensure time on the jump server is accurate. Use the command #ntpdate pool.ntp.org to sync time.

root@gateway:~# ntpdate pool.ntp.org

26 Sep 16:32:03 ntpdate[15219]: adjust time server 133.243.238.244 offset -0.124881 sec

4. Ensure that Root SSH login on the jump server is enabled and SSH key-based authentication is enabled in SSHD. The below example enables root access only from the ip 127.0.0.1 and it allows only key-based authorization which makes it secure. Add the following parameters to the END of /etc/ssh/sshd_config file.

Edit the file using the nano or vi command:

root@gateway:~# nano /etc/ssh/sshd_config

IMPORTANT: The following sshd server configuration is important.

5. Add the following parameters to the "/etc/ssh/sshd_config"  file.

#SSHD Global Settings

AllowTcpForwarding  no

PubkeyAuthentication yes

 

#SSHD localhost settings.

Match Address 127.0.0.1

path to install web panel files ( /var/www/html/ezlogin ):

You need to specify the Document root here, if it is different from default else you press enter to choose default.

Enter the path where web panel system files should be installed.

This should be preferably outside the DocumentRoot (should not be accessible via web browser) for security reasons.

If safe_mode restriction is enabled, this path should be allowed for include with safe_mode_include_dir

The directory should not exist, but its parent directory should exist.

path to install web panel system files ( /var/www/ezlogin ):

If you need to access the Ezeelogin jump server webpanel as  www.yourdomain.com  choose   "   /  "  & change your document root to  {your existing document root}/ezlogin. For example, If your document root is /var/www/html change to /var/www/html/ ezlogin, else press enter to choose default.

For example, if the DocumentRoot of http://www.yourdomain.com/ is /usr/local/apache/htdocs/yourdomain and you specified /usr/local/apache/htdocs/yourdomain/ezlogin as path to install web panel, the web panel would be accessible as http://www.yourdomain.com/ezlogin/. In this case the REQUEST-URI would be ’/ezlogin/’.

If you specified DocumentRoot itself as the path to install web panel files, it would be ’/’

URI path to access the web panel ( /ezlogin/ ):
