Established connection timeout and maximum connections recommended?
Hello,
how big timeout do you advice for established connections and what size of connection table you advice to server with 1gbit/s shared line + HDD 7200rpm?
default values on my centos:
net.netfilter.nf_conntrack_tcp_timeout_established = 432000 (5 days!)
net.nf_conntrack_max = 65536
i tweaked this way:
net.netfilter.nf_conntrack_tcp_timeout_established = 86400 (1 day)
net.nf_conntrack_max = 75536
The server is used for most various tasks like hosting, rdp, torrent, rsync large backups, email, ssh proxy
Im curious if i can afford lets say 10 minutes established timeout and lets say 300,000 conntrack max ?
Thx
