OpenVPN
Building OpenVPN and friends.
OpenVPN
OpenVPN is easy to install and the configuration instructions are straightforward.
A minor Solaris point is the absence, by default, of the LZO compression libraries. So add --disable-lzo to the configure line and comment out the comp-lzo lines in the server and client config files.
Daemon Death Problems
A word of warning on Solaris is that if the daemon dies, for example by hitting ^C when testing, the daemon leaves the tun0 interface up and or plumbed. The next instance of openvpn to run will fail with the cryptic: Can't set PPA 0: File exists (errno=17).
ifconfig tun0 unplumb
may cure the problem.
