Connection reset: (maybe the wrong forum)

Hello! I have tried to stream to an icecast server through stunnel usung liquidsoap. Somewhere the stream gets stuck. I want to where. Maybe I should have posted this on the Tor mailing list first, since the traffic is forwarded through Tor. But before the stream went to Tor, it went through stunnel. The liquidsoap snippet which tries to stream (password,mount name, stream description and stream name modified: output.external(id="Tor", fallible=true, reopen_delay=3.0, %vorbis(quality=0.4 , samplerate=48000, channels=2), "/usr/bin/oggfwd -n streamname -d 'stream description' localhost 9887 password /mount", mksafe(buffer(full))) I had a script which was supposed to pick up this stream and forward it on a cloud server (passwords etc. modified): #!/bin/bash /usr/bin/curl -V http://localhost:9887/mount | \ /usr/bin/torsocks /usr/bin/oggfwd -n streamname -d 'stream description' superdupersecret.onion 8000 password /mount #/usr/bin/curl -T - -s --socks5 localhost:9050 http://superdupersecret.onion/mount exec "/home/per/bin/test.sh" stunnel.conf on cloud: setuid = stunnel4

stunnel5 to stunnel4 not work
by Tu, Robin 15 Jan '20

15 Jan '20

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

How to start stunnel4 service directly after installation, without reboot
by Tu, Robin 15 Jan '20

15 Jan '20

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)...

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

Stunnel-5.55 client close TLS socket before it could read more bytes
by Ming Lu 13 Dec '19

13 Dec '19

Hello, May I please have help on this issue? Thanks in advance! I had a stunnel server and client communicating with TLSv1.2 (both of them are stunnel 5.55 and OpenSSL-1.1.1d) on CentOS 7 based Linux (kernel was updated as 4.19.0). The case is that client sends a HTTP request to server, and then server responds a payload with more than 640KB size. Normally, the server will close the connection by sending an alert firstly. The issue is that sometimes (not 100% reproducible), stunnel client reported: "TLS socket closed (read hangup)". and then closed the TLS socket. So I could find an alert sent from client to server firstly from tcpdump. Consequently, this caused the application reported "unexpected end of input?" as there should be more data to be received. I added a few debug logic and I indeed found that: there were occurrences that if stunnel client did not close the TLS socket, it could read more data from TLS socket in next poll loop: -------------------- 03:59:46 localhost stunnel: LOG6[0]: MingL: POLLRDHUP: 8192 03:59:46 localhost stunnel: LOG6[0]: MingL: ioctlsocket: 0 03:59:46 localhost stunnel: LOG6[0]: MingL: bytes: 0 <== client didn't close the sock in my debug version. 03:59:46 localhost stunnel: LOG6[0]: MingL: after checking 03:59:46 localhost stunnel: LOG6[0]: MingL: s_poll_wait: return 1 03:59:46 localhost stunnel: LOG6[0]: MingL: sock_can_rd: n 03:59:46 localhost stunnel: LOG6[0]: MingL: sock_can_wr: Y 03:59:46 localhost stunnel: LOG6[0]: MingL: ssl_can_rd: n 03:59:46 localhost stunnel: LOG6[0]: MingL: ssl_can_wr: n 03:59:46 localhost stunnel: LOG6[0]: MingL: pending: 1 03:59:46 localhost stunnel: LOG6[0]: MingL: write to sock 18432 03:59:46 localhost stunnel: LOG6[0]: MingL: read_wants_read Y 03:59:46 localhost stunnel: LOG6[0]: MingL: write_wants_writen 03:59:46 localhost stunnel: LOG6[0]: MingL: read from TLS 10168 <== then I observed the further read from TLS. -------------------- Any help will be appreciated!

It wasn't clear if you were changing the port number of the sshd service (on your server) or the port you had open on your firewall/router. I suspect that your ISP is blocking incoming connections to port 22. The port number you use for sshd on the server is not relevant. -chris > On Thu, Dec 12, 2019, 9:44 AM Christopher Schultz > <chris(a)christopherschultz.net <mailto:chris@christopherschultz.net>> wrote: > > Matt, > > On 12/12/19 11:01, Matt Thomas wrote: > > Server is 192.168.0.10 > > Router is 192.168.0.1 > > > > It works fine internally:) > > > > I add a port forward in the router for port 22 pointed at .0.10. > Routers > > firewall all ready is configured to accept ssh on port 22 from any > any. > > > > When ever anyone attempts to connect to the server, a pop up shows > on my > > screen.
