Subject: net.ipv4.tcp_rmem does override net.core.rmem_max?
Date: Tue, 16 Feb 2016 18:04:18 +0100 [thread overview]
Message-ID: <56C35692.7010807@nh2.me> (raw)
`man tcp` says `net.ipv4.tcp_rmem`'s max value *does not override*
`net.core.rmem_max` (see [1] [2]) but I found in practice it does.
The person in this thread
http://stackoverflow.com/questions/31546835/tcp-receiving-window-size-higher-than-net-core-rmem-max/35438236
confirms my finding.
Is the man page (and ip-sysctl.txt) outdated?
Thanks for clarifying!
Niklas
