7 programs to monitor your bandwidth from the Linux shell

[ Thanks to Linuxaria for this link. ]

"IPTState: This software is a top-like interface to your netfilter connection-tracking table. Using iptstate you interactively watch where traffic crossing your netfilter/iptables firewall is going, sort by various criteria, limit the view by various criteria. But it doesn?t stop there: as of version 2.2.0 you can even delete states from the table!

"pktstat displays a real-time list of active connections seen on a network interface, and how much bandwidth is being used. Partially decodes HTTP and FTP protocols to show what filename is being transferred. X11 application names are also shown.

"NetHogs is a small ?net top? tool. Instead of breaking the traffic down per protocol or per subnet, like most tools do, it groups bandwidth by process. NetHogs does not rely on a special kernel module to be loaded. If there?s suddenly a lot of network traffic, you can fire up NetHogs and immediately see which PID is causing this. This makes it easy to indentify programs that have gone wild and are suddenly taking up your bandwidth."
