[tiger83052 4]

Hi

I tried both ssh and ssl connection and haven't figured how to do it correctly

my os is OSX El Capitan PB3

 

installing ssh :i entered : https://airvpn.org/ssh/

generated the files " ssh port 53 "

and then went to terminal and made the cd command to the folder where ssh file in

and run the command " AirVPN_DE-Frankfurt_Aquilae_SSH-53.sh " but i get this error

i get : -bash: AirVPN_DE-Frankfurt_Aquilae_SSH-53.sh: command not found
when i try this command ./openvpn "AirVPN_DE-Frankfurt_Aquilae_SSH-53.ovpn" also got the same error

 

my ssl setup :

 

i followed all the steps and at terminal i entered this command :

"tar -xzvf stunnel-5.22.tar.gz
cd stunnel-5.22
./configure && make && make check && sudo make install"

i get this error :

clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [stunnel] Error 1
make[1]: *** [all] Error 2
make: *** [all-recursive] Error 1

and here is the complete log : http://justpaste.it/ms2u
