# Memo

## On Ubuntu you can use the netstat utility to see open ports:

    $ netstat -tulpn

## You can also verify that stunnel is running using nmap to check if the stunnel port is open:

    $ sudo nmap localhost

## Generate 2048 key:

    openssl genrsa -out cleserveur.key 2048

## Generate CSR :

    openssl req -new -key cleserveur.key -out demandecertif.csr

## Generate auth certificat :

    openssl x509 -req -days 365 -in demandecertif.csr -signkey cleserveur.key -out certserver.crt

## Generate pem :

    cat cleserveur.key > server.pem && cat certserver.crt >> server.pem

## stunnel should have direct internet access:

     sudo route add 37.187.109.75 gw 192.168.1.1 dev wlp2s0
