Webmin on Entware for DD-WRT

...I can do that.

I'm using a Buffalo WZR-600DHP Router

Well as it turns out the opkg install command doesn't allow for wildcards, so after a quick bit of research, I located a webpage where a nice guy had come up with this command;

opkg list | grep packagename | awk '{print $1}' | xargs opkg install

List of helpful links;
