Often you have to edit config files or other files by hand. Personally I hate vi or similar editors. You can always copy them to your computer and edit them there, but an easier way are to edit them direct with nano. This are an tips how to install nano on your vu+ duo2 box.
Try first get nano via package manager:
opkg update
opkg list | grep -i nano
If you not can get nano this way, do this:
cd /sbin
wget http://downloads.nas-central.org/LS2_MIPSel/Packages/mipsel-nano_2.0
mv mipsel-nano_2.0 nano
chmod +x nano
Now you can edit your files via nano.
