I'm working on openvpn over stunnel. My configuration can work with windows and linux. both are stunnel4. But it never work out in android. I have ubuntu18.04 and set as stunnel4 server side. I try to get connected with android stunnel: SSLSocks<https://github.com/comp500/SSLSocks/releases/tag/0.0.17-beta>, which should be compiled with stunnel5. It simply not work. I got "NETWORK_EOF_ERROR" time to time. If I remove stunnel tunnel, it will just work. So I think it's stunnel5 to stunnel4 issue. But how to avaoid such issue? Best Regards Robin

I'm testing openvpn over stunnel4 and I found a weird issue: I have to restart my Ubuntu 18.04 to be able to start the stunnel service. Don't know why I couldn't start the service dicrectly by : Systemctl start stunnel4 OS: Ubuntu 18.04 #>apt install stunnel4 and generate a conf like this: cert=/etc/stunnel/server.crt key=/etc/stunnel/server.key [openvpn-localhost] accept = 8443 connect = 127.0.0.1:11000 Now start the service: #>systemctl start stunnel4 #>systemctl status stunnel4 stunnel4.service - LSB: Start or stop stunnel 4.x (TLS tunnel for network daemons) Loaded: loaded (/etc/init.d/stunnel4; generated) Active: active (exited) since Wed 2020-01-15 14:40:11 CST; 10min ago Docs: man:systemd-sysv-generator(8) Tasks: 0 (limit: 4915) CGroup: /system.slice/stunnel4.service Jan 15 14:40:11 iZ8vb6j45u355dm236tpibZ systemd[1]: Starting LSB: Start or stop stunnel 4.x (TLS tunnel for network daemons)... Jan 15 14:40:11 iZ8vb6j45u355dm236tpibZ stunnel4[3583]: TLS tunnels disabled, see /etc/default/stunnel4 Jan 15 14:40:11 iZ8vb6j45u355dm236tpibZ systemd[1]: Started LSB: Start or stop stunnel 4.x (TLS tunnel for network daemons). Why it exited? But after reboot, same command will just work. Is it a bug? I want to find a way to start it directly after installation. Please help! Best Regards Robin
