A jump server, jump host or jump box is a system on a network used to access and manage devices in a separate security zone. A jump server is a hardened and monitored device that spans two dissimilar security zones and provides a controlled means of access between them.

A jump host, also known as a bastion host, is a server that acts as a bridge to access other servers in a private network. It serves as a secure gateway, allowing controlled access to internal hosts. When connecting to servers within a private network, you must first connect to the jump host before accessing the internal servers.

A jump server is an intermediary device responsible for funneling traffic through firewalls using a supervised secure channel. By creating a barrier between networks, jump servers create an added layer of security against outsiders wanting to maliciously access sensitive company data.

A jump host, also known as a jumpbox or jump server, is a network device or virtual machine that acts as an intermediary to a remote network. It grants authorized users access to a remote network, allowing them to troubleshoot and manage devices within the LAN without needing to send a technician on-site.

Dec 13, 2022 · In a nutshell, an SSH Jump server is a Linux server that is used as a gateway to other Linux servers on a private network over the SSH Protocol.

Mar 30, 2021 · What is an SSH Jump Server? An SSH jump server is a regular Linux server, accessible from the Internet, which is used as a gateway to access other Linux machines on a private network using the SSH protocol. Sometimes an SSH jump server is also called a “jump host” or a “bastion host”.

Feb 8, 2025 · Using a Jump Host improves security by centralizing access and reducing exposure of internal servers to the internet. With SSH, you can streamline connections through a Jump Host using ProxyJump or SSH Agent Forwarding, making access seamless and efficient.

Nov 15, 2024 · A jump server is a computer that acts as a safe bridge between networks in different security zones. It’s a hardened device that administrators use to safely bypass firewalls that isolate public networks from private ones.

Mar 25, 2020 · With this command, you are tunneling the port 1521 of localhost to the port 1521 of dbserver. In other words, you are firstly doing an SSH connection to jumphost with user myusr, then another SSH connection to appserver with user appusr, and finally forwarding port 1521 from localhost to dbserver.

Mar 9, 2022 · Jump Host: Jump Host is an intermediary host or an SSH gateway to a remote network, through which a connection can be made to another host in a dissimilar security zone, for example a demilitarized zone (DMZ). It bridges two dissimilar security zones and offers controlled access between them.
