Root privilege is required to install and run AmritaVPN. You would need a root login shell to succesfully run 'make install'. If you're logged in as root, then of course you already have a root login shell. Otherwise you must do: 'su -' instead of simply 'su' at command prompt.
amvpn.conf will be installed to '/etc' directory (this can be changed during 'configure' step). If an already existing amvpn.conf is found, the existing file is saved under the name amvpn.conf.orig. If required, you can move your existing configuration from this saved file to amvpn.conf./etc/modules.conf file is modified
(if required)so that VPN tunnel device driver is automatically loaded
when required. The existing modules.conf is saved under the name
modules.conf.dist. Normally there is no reason for the user to
bother about this saved file.
Default locations can be overriden during 'configure'.
