Please, please, try to use the packages offered by the VTun Devel
Team, or else your distribution. The devel team and charitable users
often don't have the spare time to spend trying to re-create a custom
environment to debug every problem. If your distro offers you an
installation suite, then of course use that; they will be
well-prepared to help you and we will be happy to address issues
passed on from them. If your OS or distro isn't listed, please try a
source package, and then the source, before trying a 3rd-party
non-distro package. The level of support you get can only be better
if it's easier to replicate your exact setup.
Yes, you will probably need a tun RPM for these vtun RPMs, and even
if your distro provides the kernel module; it can be important for
cohabitation with other tun-using products. If you are packaging a
tun-based VPN app, please set a dependency on the tun RPM; you should
know why! Send me (bishop) email if you wish to discuss it.
