Diagnosing resolution problems
Traceroute is a computer network diagnostic tool for displaying the route (path) and measuring transit delays of packets across an Internet Protocol (IP) network.
Traceroute outputs the list of traversed routers in simple text format, together with timing information
Traceroute is available on most operating systems.
On Linux:
If the last line of the output does not list 8.8.8.8 as the final hop, or if there are significant timeouts, there may be a network problem preventing you from contacting our servers.
sudo traceroute -n -w 2 -q 2 -m 30 8.8.8.8
cPGS :: cPanel Game Servers
cPGS can be installed in WHM in the “Manage Plugins” section, remote servers can be installed after that using the remote server install feature in the “Gameserver Management” section of WHM.
cPGS won’t be officially supported until version 1.0.0.
This add on provides hosting companies the ability to offer popular game server hosting within the framework of cPanel®.What has been a traditionally tedious task has now been simplified for “point and click” simplicity.

iptables/netfilter’s geoip match
Netfilter and iptables are building blocks of a framework inside the Linux 2.4.x and 2.6.x kernel. This framework enables packet filtering, network addresss [and port] translation (NA[P]T) and other packet mangling. It is the re-designed and heavily improved successor of the previous Linux 2.2.x ipchains and Linux 2.0.x ipfwadm systems. To learn more about iptables/netfilter you should visit www.netfilter.org.
This framework is modular and easily let you extend the features. This is exactly what geoip is : an extension to iptables/netfilter that allows you to filter, nat or mangle packets based on the country’s destination or provenance.
Wordpress Login LockDown
Limits the number of login attempts from a given IP range within a certain time period.
Description
Login LockDown records the IP address and timestamp of every failed login attempt. If more than a certain number of attempts are detected within a short period of time from the same IP range, then the login function is disabled for all requests from that range. This helps to prevent brute force password discovery. Currently the plugin defaults to a 1 hour lock out of an IP block after 3 failed login attempts within 5 minutes. This can be modified via the Options panel. Admisitrators can release locked out IP ranges manually from the panel.
Installation
1. Extract the zip file into your plugins directory into its own folder.
2. Activate the plugin in the Plugin options.
3. Customize the settings from the Options panel, if desired.
