Title: Re: limit simultaneous connections

 If you're using linux, you could use iptables with a connlimit match to do this, e.g.   # rejects smtp connection if their are already 2 established connections from same source ip iptables  -p tcp --syn --dport 25 -m connlimit --connlimit-above 2 -j REJECT   # rejects smtp connection if their are already 2 established connections from same source /24 subnet iptables  -p tcp --syn --dport 25 -m connlimit --connlimit-above 2 --connlimit-mask 24  -j REJECT   J.T. ----- Original Message ----- From: Zilber, Alexey To: [EMAIL PROTECTED] ; qmail-ldap@qmail-ldap.org Sent: Monday, May 29, 2006 8:51 PM Subject: Re: limit simultaneous connections Actually, I would love to see concurrencyremote per ip or subnet, with a default rule.. -------------------------- Sent from my BlackBerry Wireless Handheld -----Original Message----- From: Diego Zuaneti Arruda <[EMAIL PROTECTED]> To: qmail-ldap@qmail-ldap.org <qmail-ldap@qmail-ldap.org> Sent: Mon May 29 16:42:50 2006 Subject: limit simultaneous connections   Hi all,    Somebody knows some patch to limit simultaneous connections from the same IP ?
