If you do make changes to the PHP configuration poool, or the php.ini default settings, you should restart PHP-FPM after, with the instructions included above. Here are a couple of links to help you locate the file(s) on your system - you might want to double-check to see if there are other files? With tcpdump, I observe a packet sent to and a reply from the client no matter the settings. I have repeated all of your work and got the same results. One thing to double-check is that you are updating the correct php.ini file (it is possible there is more than one - one for your browser settings, and one for the command-line, for example) and the location of these files is not consistent, as it depends on a number of other factors. I observe a difference in the man page for sshdconfig between Ubuntu server 16.04 and 20.04: under ClientAliveCountMax 16.04 does not have this part Setting a zero ClientAliveCountMax disables connection termination. Some of these values are set during installation, in the PHP configuration pool you set up here:Īdditionally, some of these settings are maintained in the php.ini file found on your server/computer.
