FYI Debian Security Team recommends setting new sysctl value net.ipv4.tcp_min_snd_mss to 536, even though they (Debian) are preserving the default kernel value

FYI Debian Security Team recommends setting new sysctl value net.ipv4.tcp_min_snd_mss to 536, even though they (Debian) are preserving the default kernel value of 48 for compatibility.
- LinuxBender 7y agoThats cool. In CentOS the default is 256. The settings are a little different though. net.ipv4.route.min_adv_mss = 256 net.ipv4.tcp_base_mss = 512 net.ipv6.route.min_adv_mss = 1220
- londons_explore 7y agoIt's worth noting that lwIP, the network stack used by most microcontroller based IoT devices, has a very low MSS. It's configurable, but typically defaults to 512.
- CloudNetworking 7y agoThat's very interesting. I have only seen those defaults in some... "special" satellite links.
