Re: How to use sudo to get a root shell?

I am trying to get a vpn setup. I thought logging in with su - might
have been a problem. When I run the following command with a root
terminal it is looking in my home directory:
root@crunchbang:/etc/openvpn/vpn_book# lsof|grep openvpn
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file
system /home/joe/.gvfs
