Hello, Just out of curiosity, on a linux box (Ubuntu 18.04) what triggers a TCP Keep-Alive every 10 seconds? The value that I got from /proc/sys/net/ipv4/tcp_keepalive_intvl is 75 seconds. Thank you in advance. Roberto
Hello, What application is this? Check its settings/configuration. I guess application could override system-wide value.
While browsing via HTTPS (TLSv1.2) for instance to https://www.theguardian.com. I see occurrences of keepalives from my host every 10 s, for every TCP stream.
I think you're right; it could be the HTTP keepalive directive on the webserver; I'll do some experiments with an Apache web server.
Thanks for pointing me in (what appears to be) the right direction.
HTTP keepalives and TCP keepalives are unrelated. See https://stackoverflow.com/questions/9334401/http-keep-alive-and-tcp-keep-alive for an explanation of the difference.
