VPN connection fails to connect after upgrading ubuntu 16.04 [on hold]












0














I have started using Ubuntu version 16.04 for a while. My problem occurs every time I upgrade Ubuntu.

The vpn connection works perfectly fine after the installation of the operating system, but as I upgrade the system for one or two times, the VPN connection fails in successfully getting established.

I tried changing to systemd as I thought it might solve the problem by doing what XModulo has described,but I gained no result.

I do not understand the meaning of the tail -f /var/log/syslog output, so I bring it here:

    Did you change firewall rules or install / update UFW?

  • Thank you very much for reminding me of the firewall. As I turned it off the VPN service started working properly. There were bunch of rule for different services including pptpd. Thank you very much again saving me.

Is this a new Fibonacci Identity?

Image
6 1 $begingroup$ I have found the following Fibonacci Identity (and proved it). If $F_n$ denotes the nth Fibonacci Number, we have the following identity begin{equation} F_{n-r+h}F_{n+k+g+1} - F_{n-r+g}F_{n+k+h+1} = (-1)^{n+r+h+1} F_{g-h}F_{k+r+1} end{equation} where $F_1 = F_2 = 1$ , $r leq n$ , $h leq g$ , and $n, g, k in mathbb{N}$ . It is not too hard to show that this identity subsumes Cassini's Identity, Catalan's Identity, Vajda's Idenity, and d'Ocagne's identity to name a few. I have done a pretty thorough literature review, and I have not found anything like this, but I am still wondering if anyone has seen this identity before? I found this by accident after noticing some patterns in some analysis work I was doing, so if this is already known I would be curious to see w...
