In the neigborhood of 2008-06-03 07:58 -0400, Patel Dippen-CDP054 argued: > Will Stunnel work for UDP data? Stunnel only accepts TCP connections. > We have traffic going into the Server on UDP and outbound from the Server on TCP. You'll want an actual VPN protocol to handle that then. Or consider using a better protocol - what you describe makes the firewalls cry. > My understanding is that OpenSSL implemented the DTLS protocol (TFC > 4347: to support UDP data) in version 0.9.8 (OpenSSL: a free and popular > implementation of TLS added support for DTLS with version 0.9.8.) Not supported in Stunnel currently. -- Brian Hatch Always yield to temptation, Systems and because it may not pass Security Engineer your way again. http://www.ifokr.org/bri/ Every message PGP signed

Is anyone using Stunnel for tunnelling Voip?
by Errol Samuels 03 Jun '08

03 Jun '08

Hello All, I am currently researching a solution for tunnelling VoIP traffic since VoIP is blocked in the country concerned. It appears that the ISP is targeting OpenVPN and OpenSwan and blocking them so I want to try something different. My solution based on OpenVPN worked great until it got blocked by the ISP about a week ago. It was using an OpenVPN server hosted in a US Datacenter and the VPN clients were simply routers with third party Linux firmware with the OpenVPN client embedded in the firmware. I am also investigating the possibility of tunnelling OpenVPN through SSH but I have to watch my IP overheads here because the ISP watches the upload bandwidth as well! Has anyone attempted or had any success using stunnel for a similar scenario as I have mentioned? Thanks in Advance Regards, Errol

Can I put an accept+connect pair anywhere in the conf file?
by Ben Stover 02 Jun '08

02 Jun '08

The *.conf file is divided into several sections: [imaps] .... [pop3s] .... [smtps] ..... Are these "section headers" just comments and can I put my accept+connect pair on an arbitrary place in the *.conf file (as long as they are preceeded by their own section header [foobar] ? Ben

Connecting to mySQL from Windows
by Alistair Scott 02 Jun '08

02 Jun '08

Hi everyone I have a mySQL database that I need to connect to through SSH. I have successfully setup a connection to it using Plink. However, I'm running this from a batch file and I'd like a more elegant solution - that's where stunnel comes in I think. Rather than running a batch file, I'd like to run the connection as a Windows service - which I think this is achievable with stunnel. Trouble is, I can't work out how to do it. This is what I'm trying to achieve... Windows computer connects to mySQL server through SSH. Forwards a port to the mySQL server port 3306. Application on Windows computer connects to local forwarded port & therefore connects to the mySQL db at the remote end. I was hoping that someone could give me a pointer as to how I can set this up. Thanks in advance. Al

Right around 2008-05-30 13:51 -0400, Patel Dippen-CDP054 suggested: > Is the true? I have a similar issue. I have never implemented SSL or > Stunnel. But, on whatever readup I have done so far, it seems Stunnel is > a tunneling protocol (IPnIP). So, you do have to have Stunnel on the > other end to extract the IP packet. Stunnel puts data inside SSL, inside TCP. Just like HTTPS is HTTP (data) inside SSL, inside TCP. You can think of the cleartext data inside the SSL tunnel for both of those examples. Yes, the data needs to be extracted from the SSL stream in both cases, but the application that gets it doesn't need to know diddly about it. > I mean if you are saying it will work, that's great news for me. It works if Stunnel is on one side and an SSL client or server is on the other side. > Our Server will have OpenSSL implementation but we plan to deploy > Stunnel on the Client machine.
