¿Cómo evito que SSH se agote?

How do I stop SSH from timing out?

To set the SSH keep alive option on the server:

1. Log in as root.
2. Edit the file at /etc/ssh/sshd_config.
3. Add this line to the file: ClientAliveInterval 60.
4. Save the file.
5. Restart sshd on the server.

Load your connection session. In the Category pane, click Connection. Under Sending of null packets to keep session active, in the Seconds between keepalives, type 240. With this configuration, PuTTY sends a packet to the server every 240 seconds (4 minutes) to keep the connection alive.

How to make your SSH Terminal shell sessions last longer on macOS

1. Move into your SSH settings folder. cd ~/.ssh.
2. Create a local SSH config file. nano config.
3. Add in a session variable. ServerAliveInterval 60. Write out and save the file.

A server request may time out because it was blocked from ever leaving the computer or network and never got to the server. Firewall and router port blocking settings can prevent outgoing requests to servers. Reconfiguring the Firewall or router to allow the request to pass will fix the problem.

The default timeout interval is 0 minutes. Use this value, if you do not want the SSH session to expire. The minimum timeout interval is 2 minutes. The maximum interval is 9999 minutes.

On the server, head over to the /etc/ssh/sshd_config configuration file. The ClientAliveInterval parameter specifies the time in seconds that the server will wait before sending a null packet to the client system to keep the connection alive.

In theory, an SSH connection can last indefinitely. It can be explicitly terminated by either side at the SSH layer (with a FIN packet) or abnormally terminated at the TCP layer (with a RST packet).

Usually, the SSH connection timeout occurs due to bad server settings, wrong IP hosts, firewall restrictions, etc.

This default varies depending on your system. Some systems use a default as low as five seconds, and some go as high as two hours; the average is typically around three to five minutes. Your SSH connection, if it has not been modified to change the timeout on either the server or client end, will use this timeout.

Type the set command at the igivasrv:ssh_timeout prompt to set the timeout interval for the SSH session. The following message is displayed (the value is an example): Note: The session timeout cannot be less than 2 minutes and more than 9999. Set 0 for no timeout.

Prevent SSH timeout on the client side. If you’re on Mac or Linux, you can edit your local SSH config file in ~/.ssh/config and add the following line: ServerAliveInterval 120. This will send a “null packet” every 120 seconds on your SSH connections to keep them alive.

Here’s how to keep your SSH sessions alive and prevent the SSH timeout: By sending a “null packet” between the client and the server at a specified interval that is smaller than the timeout value, we can avoid SSH timeout.

This option applies to pro‐ tocol version 2 only. ClientAliveInterval Sets a timeout interval in seconds after which if no data has been received from the client, sshd (8) will send a message through the encrypted channel to request a response from the client. The default is 0, indicating that these messages will not be sent to the client.

The default is “yes” (to send TCP keepalive messages), and the server will notice if the network goes down or the client host crashes. This avoids infinitely hanging sessions. To disable TCP keepalive messages, the value should be set to “no”.
