Hi guys been working at this for a long time now with no results. I am using nslu2 and this is what i have done i cant type the full url name because I am a new to the site but i use it correctly when typing on my system

wget ipkg.nslu2-linux.org/feeds/optware/oleg/cross/stable/tinyproxy_1.6.4-3_mipsel.ipk
and then I edit the conf file so i dont have to after it is installed. Now I have my tinyproxy.ipk ready to install from my local directory
/home/root/workdir/tinyproxy.ipk
how do install this? I have tried

ipkg -d /home/root/workdir/tinyproxy.ipk install tinyproxy.ipk
and
ipkg -d ipkg.nslu2-linux.org/feeds/optware/oleg/cross/stable/tinyproxy_1.6.4-3_mipsel.ipk install tinyproxy.ipk

but no luck. What am I missing?
I know i can just install this from a repo and then edit the conf file but I install this on many systems and I need to have the ipk ready to install so that i save a lot of time. Thanks
