|Limit number of SSH connections per user to 1
||I want to successfully limit the number of SSH concurrent connections to 1 per user.

||We have an ongoing issue with our server where DROP entries are added to iptables for the ip addresses of some of our heavy traffic website clients. This seems to be unrelated to csf or any rule in iptables as the DROP entry still appears with csf disabled and all iptables rules cleared. It seems that there is another process or application adding the DROP entries.
Experience needed in iptables...
