Tcpdump on openwrt

Question

I'm looking for a tcpdump binary that runs on openwrt. The website only shows source code that must be built. Anybody point me to a location that contains a prebuild binary? Thanks.

Answer 1

I suggest to set up a working repository, i.e.:

https://downloads.openwrt.org/chaos_calmer/15.05-rc2/x86/generic/packages/base/

You can put the url on your OpenWRT system under /etc/opkg.conf. Using opkg you do not have to deal with all the dependencies.

opkg update
opkg install tcpdump

If there is no internet connection on the Openwrt system, and there is no local repository deployed, the solution above works as well, but it is more painful and consumes more time.

Answer 2

You find binaries at http://downloads.openwrt.org/snapshots/trunk/

but you have to use the right one for your hardware plattform

e.g for x86 http://downloads.openwrt.org/snapshots/trunk/x86/packages/tcpdump_4.2.1-1_x86.ipk

The prefered method is to use opkg to install the package
