If im using SSH Connection on my Server and starting Ovpn connection Im timing out. I already read that i need to add Rules for that but i dont understand how to do it.

Code

user@home:# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 9001

You mean you're getting idle timed out? Broken pipe?

You mean you're getting idle timed out? Broken pipe?

Yes correct.

[captainspalding]

Yes correct.

I was having this same issue with DO droplets and AWS instances. These boxes would break pipe every 60s. My fix was to add the following line at the bottom of my client's /etc/ssh/ssh_config

Code

ServerAliveInterval 50

This sends a keepalive every 50 seconds.
Just to reiterate, this is on the client SSH config, not the server.

I first tried messing with the following two lines on the server's config, /etc/ssh/sshd_config:

Code

ClientAliveInterval 28800
ClientAliveCountMax 3

But without adding the line in the client side config it did not work.
