How to Configure Custom SSH Connections to Simplify Remote AccessĪdditionally, on the remote machine, you can also instruct the sshd daemon to consider connections over IPv4 by using the above directive in the /etc/ssh/sshd_config file.Here is a useful starter guide on configuring user specific ssh configuration file: The accepted values are “ any”, “ inet” for IPv4 only, or “ inet6”. So you can consider forcing ssh connections over IPv4 only, using the syntax below: # ssh -4 Īlternatively, use the AddressFamily (specifies the address family to use when connecting) directive in your ssh configuration file /etc/ssh/ssh_config (global configuration) or ~/.ssh/config (user specific file). OpenSSH supports both IPv4/IP6, but at times IPv6 connections tend to be slower. In this article, we will share four useful tips on how to speed up remote SSH connections in Linux. However, when you try to start multiple connections in succession, this causes an overhead (combination of excess or indirect computation time, memory, bandwidth, or other related resources to carry out the operation). There are several bottlenecks to this process, one scenario is when you are connecting to a remote server for the first time it normally takes a few seconds to establish a session. One of the challenges with remote server management is connection speeds, especially when it comes to session creation between the remote and local machines. SSH is the most popular and secure method for managing Linux servers remotely.
