I got it working in openwrt. Im sure its possible in dd-wrt too, but I didnt manage to do it.

To install in openwrt, simply install openwrt kamikaze according to instructions and then do:
opkg update
opkg install tcpdump

Telnet to your router running dd-wrt an copy-paste below lines and it should work fine. You don't need jffs2. It's assumed you have ipkg installed on your firmware version. std has it and probably mini also.

mkdir -p /tmp/smbshare/tmp/ipkg &&
cd /tmp/smbshare/tmp/ipkg &&
wget http://downloads.openwrt.org/whiterussian/packages/libpcap_0.9.4-1_mipsel.ipk &&
ipkg -d smbfs install libpcap_0.9.4-1_mipsel.ipk &&
wget http://downloads.openwrt.org/whiterussian/packages/tcpdump_3.9.4-1_mipsel.ipk &&
ipkg -d smbfs install tcpdump_3.9.4-1_mipsel.ipk &&
LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/tmp/smbshare/usr/lib" &&
PATH="$PATH:/tmp/smbshare/usr/sbin"

just run it with command: tcpdump
Note that you'll have to run these lines everytime you power-cycle the router

If i have a linux box with samba installed and a share, and this linux box also has tcpdump installed on it.

Is there a way to put the tcpdump program in the share folder of the linux box. load this share into dd-wrt and run that tcpdump on the router and have it also store it's results back to the share on the linux box?

I am looking not to have to installed extra stuff onto the router. Its eko 12548 std. on a wrt54gl.

Thanks.

Thanks jozza

I was able to use and run tcpdump per your instructions on WRT54G V3.1 4MBFlash/16MB RAM latest SVN

DD-WRT v24-sp2 (05/25/10) mini - build 14473

and I already ordered monster router RT-N16 lol.
well, I think I'll find somewhere space for it.
