Dear all,
I'm new here and I've just signed up to the mailing list to report a problem
I am facing with pptpclient.
My setup is ubuntu 15.10 kernel 4.2.0-16-generic with pptp-linux
package installed (1.8.0-1
version)
The ppp package installed for dependency is 2.4.6-3.1
The pptp server is Mikrotik router.
The problem appeared after upgrade from ubuntu15.04 to 15.10.
The pptp conection is established successfully.
The problem is that i cannot reach other computers via SSH and nfs services.
The output of SSH try is
OpenSSH_6.9p1 Ubuntu-2, OpenSSL 1.0.2d 9 Jul 2015
