I have an Ubuntu Server (headless) box, which needs to establish a PPTP connection (as client) to a PPTP server elsewhere.
The box's sole purpose is to connect to the VPN, and download files for backup purposes. So keeping the VPN connection up is important.
After an afternoon Googling all I've come up with are several dozen ways to skin the same cat, and the cat is feeling a bit unloved. So any recommendations?
Sorry, I don't know the answer to your question. My first thought was why not using ssh. I looked up pptp at http://en.wikipedia.org/wiki/Point-to-Point_Tunneling_Protocol#Security
and I read this
"PPTP has been the subject of many security analyses and serious security vulnerabilities have been found in the protocol. The known vulnerabilities relate to the underlying PPP authentication protocols used, the design of the MPPE protocol as well as the integration between MPPE and PPP authentication for session key establishment. PPTP is (as of Oct 2012) considered cryptographically broken and its use is no longer recommended by Microsoft." http://en.wikipedia.org/wiki/Point-to-Point_Tunneling_Protocol#cite_note-7
That made me think! My first though was that any VPN worth it's salt should surely be able to make a connection "on-the-fly" as and when needed, surely?
I know this doesn't help, (sorry) by for remote backing up, I'd be thinking of rsync over ssh, or using something like unison, or Backuppc.
Sorry I can't be more helpful.
