The source information below is dated. Actually, you can still get this package from here http://www.fungible.com/openwrt/packages/ - Thanks Tim Freeman (http://www.fungible.com/openwrt/index.html). Additionally you'll have to skip the ipkg install terminfo and ipkg install ncurses ncurses-term part. I just installed the libs, added the export TERMINFO=/jffs/usr/share/terminfo and that's all.

Iftop is a terminal program which shows network activity and associated details in text form. Could be very handy for those SSH users who want to know what is going on and don't want all the overhead of graphical interfaces.


I got iftop working on my DD-WRT (WRT54GS) and this is my Dakshina to the DD-WRT/OpenWRT Gurus and Community - Thanks.

OpenWRT Tracker - very good list of available packages for OpenWRT - since OpenWRT and DD-WRT are in the process of merging, this list should only get more and more useful.

ipkg install iftop (or iftop-bangless if you wish)
ipkg install libpcap libncurses libpthread
ipkg install terminfo
ipkg install ncurses ncurses-term

This will install all the necessary packages to run iftop. All these packages may not be needed, but I am listing it here exactly the way I did it.

These packages will install under /jffs, so you need to inform your system about the location of these newly-installed libraries in these non-standard paths. Under /jffs/, I created a file named set_path, which contains the following:

#!/usr/bin/env sh

export LD_LIBRARY_PATH=`cat /etc/ld.so.conf  | tr '\012' ':'`
export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/jffs/lib:/jffs/usr/lib"

export TERMINFO=/jffs/usr/share/terminfo

I've made it executable, but it's probably not necessary

/jffs # ls -al set_path
-rwxr-xr-x    1 root     root          192 Oct 13 17:26 set_path

Every time you log in, you need to source this file as follows

. /jffs/set_path

and you should now be able to run iftop on the interface of your choice. (For me, vlan1 is WAN and br0 is LAN+WLAN).
