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

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:[email protected]>> 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.

I wasn't aware that Minecraft servers could have their ports changed like that. You can really set up your Minecraft server to listen on localhost:22 and it doesn't use UPnP or anything like that to reconfigure your firewall/router? My advice is to try configuring things like this: Router: 192.168.0.1 Forward WAN connections to port e.g. 1022 -> 192.168.0.10:1022 Server: 192.68.0.1 Accept stunnel connections on port 1022 accept=:1022 connect=localhost:22 If that works, I might even try just changing the port number of your ssh/sftp service from the "standard" port to something else and trying again without stunnel in the mix. I've never encountered an ISP which does deep packet inspection to block services. They usually just block ports. -chris > On Thu, Dec 12, 2019, 7:58 AM Christopher Schultz > <chris(a)christopherschultz.net <mailto:[email protected]>> wrote: > > Matt, > > On 12/11/19 17:53, Matt Thomas wrote: > > I need to know if Stunnel is going to accomplish what i need to do.

My home ISP blocking ssh protocol
by Matt Thomas 12 Dec '19

12 Dec '19

Hello:) I need to know if Stunnel is going to accomplish what i need to do. My home ISP blocks protocol HTTP and SSH from coming in so that people cant run their own website from home without paying the ISP for a "Business" line All i am trying to do is have a SFTP server that i can access my dang files from while i am at school, work, friends house, library or wherever. I have tried ssh on multiple random ports and made sure all firewall rules and port forward rules were correct in my home router. I know they work because i even went as far as setting up a minecraft server to just test the port forward rules out and sure enough, my friend 200 miles away can connect just fine to my home minecraft server.. But he can not connect to the ssh server. No logs are ever created on the server either because something is stoping the packet from even hitting my router, that something is my ISP Would stunnel allow me to make ssh traffic look like regular https traffic, thus allowing me to connect to my server at home so i can do my homework?? thanks -- My history test question: Give the number of automobiles produced in America during the year of your choice.
