Network load balancing is now a key feature that is required for all enterprises, especially financial companies. This capability balances network sessions like web, email, etc over multiple connections in order to spread out the amount of bandwidth used by each LAN user, thus increasing the total amount of bandwidth available. Additionally, network load balancing is commonly used to provide network redundancy so that in the event of a WAN link outage, access to network resources is still available via the secondary links. Inbound Load Balancing operates by processing traffic activity from remote users who are requesting information from your local network. Multiple communication channels are utilized for increased bandwidth to accommodate numerous sessions by remote users accessing the network and retrieving requested information. Most networks with Load Balancing capabilities benefit their local users when processing outbound information requests. This setup, inversely is known as ...

Once in the application, navigate to the following key. apps \ metacity \ keybinding_commands You'll notice a bunch of values on the right. These are the available commands that you can create for assigning to shortcut keys in the next step. Double-click on command_1 and enter in the full path to your script or executable that you are trying to run. (Note that you can use the which command from the shell to find the path most of the time) Now navigate to the key "global_keybindings", which is directly above the one we were on.
