Catalina is same as all the older OS X and macOS for this. For you, it seems the hidden ssh folder is what’s stopping your attempt to configure the file. My commands make the directory and then clobber any file you may have so don’t use the cat and expect to keep. The reason I decided for this 'project' is too keep the spirit of very old and nostalgic title: Operation FlashPoint alive by adding few customizations that have already been available for some time. However, thanks to the official MAC/LINUX release I decided to start transferring as much content from www.moddb.com and www.bistudio.com as. This website uses cookies for improving the usability. Furthermore, we use AdSense for showing ads, and the web server providing the ads may also use cookies. However, It really took me a long time to find out how to work it out under MAC OS X. Somebody suggested me to turn to netinet/tcpvar.h, but still none of the aforementioned MACRO was found. So, my question is, How to implementation TCP KEEPALIVE under MAC OS X? P.S.: my MAC OS X version is 10.8.3,and my gcc/g version is 4.2.1. Read reviews, compare customer ratings, see screenshots, and learn more about Keep it alive! Download Keep it alive!

I admit it, I’m always with a lot of applications opened, Chrome with at least 6 tabs, Skype, Slack, PHPStorm or SublimeText, Airmail or Outlook for Mac, Photoshop and terminal.
I regularly login via SSH to VPS in Digital Ocean and AWS EC2 and then run some commands like:
Then I go to the wordpress site and start adjusting the settings, but by the time I get back to the terminal (5 – 10 minutes), the SSH session is frozen, so I’m forced to open a new one. I honestly became tired of this, and I remembered that SSH was built on TCP and as such it should have some “Keep Alive” settings like on SIP (sorry I come from the call center world). And after some search online, I found that you can make this change both from the server side (SSHD: Secure SHell Daemon) or from your CLI (*nix, Linux & Mac).
All you need to do is to setup your ssh client to send a “Keep Alive” signal to the server every certain amount of seconds. So you can add the following text to your ~/.ssh/config
file:
This basically tells your computer to send “keep alive” signals to remote-host.com every 120 seconds (2 minutes). That way the session will not get frozen for that server.
If you want to enable this for all of the hosts that you connect to, then simply add the following strings instead:
This will setup the “keep alive” signal interval to 2 minutes for any host that you connect to via SSH.
After you finish editing the file, please make sure to change the permissions on the file using the following command:
And there you go, as simple as that! No more timeouts on my terminal app on my Mac OS El capitan MBP!
