I'm looking for a Linux utility (command line or GUI) that is capable of telling you the complete domain name of any connections that are made to and from your machine. An added bonus would be a utility that knows what application is making the connections.

It never ceases to amaze me how scalable Linux is!
Although that is true as well, this is more of a case of flexibility =). lsof is a great tool and it's often under appreciated. lsof can help you figure out what program is locking down a certain file or the reverse, what files a program is using; hence the name (LiSt Open Files). Another thing about lsof is that most root kits don't trojan it, so if you think your computer might be compromised and netstat doesn't show anything funny, try lsof -i, it might just pop up that otherwise hidden connection.
