Disable libwrap at runtime?
by Jans, Kert 16 Aug '08

16 Aug '08

Hi, Is it possible to disable libwrap support at runtime? I've reviewed the archives and documentation and cannot determine if this is possible. I know it is possible to compile-out support for libwrap by using: configure --disable-libwrap Is compiling-out support the only way? I'd like to disable support in a pre-build version of stunnel. Regards, Kert

I did quite a lot of trawling on the web, your website and the stunnel man pages and couldn't find any guidance on mutual ssl authentication configuration. Are you able to give me a pointer, perhaps a URL to something that contains an example? Thanks again. Cheers, -C

Stunnel connection drops after four http requests
by Renner, Christopher R 13 Aug '08

With quite a bit of help from a list member here, I have stunnel 4.25 running on OSX 1.5.4 (PHP development environment). Problem is I can only get four http requests to the server before the connection is dropped. Stunnel is still running in the background.

Hi there, Does stunnel have any in-built support for mutual SSL authentication? If not are there plans to incorporate support? Cheers, -C

Socket connection status
by Jeffrey Buck 08 Aug '08

08 Aug '08

Hi, I'm running stunnel 4.04 on ia64-redhat-linux-gnu PTHREAD+LIBWRAP with OpenSSL 0.9.7a Feb 19 2003. I have basically taken a generic TCP interface and implemented a STUNNEL client/server setup to allow the connection to transfer data using SSL. I have an issue with checking the status of the connection when a connection attempt is made. We are using ObjectSpace libraries for all of our tcp related connections so I don't have the low level calls that are actually being made, but here is a brief description of what is happenning.... We create an os_tcp_socket object and call the connect_to() method. This establishes a connection to the stunnel client on my local machine....which in turn makes the connection the the stunnel server on the remote machine. The problem I'm am having is when I can't get to the remote machine. After the connect_to() call, we check the status of the socket and unless I sleep for 5-10 seconds, it always seems to think that the connection is ok...which kind-of makes sense because it is able to connect to the stunnel client port since it is local...but in fact, if there isn't access to the remote machine, eventually stunnel will close that initial connection to that socket (that where the 5-10 second delay seems to help). The status I really want is weather or not the entire connection was successful through stunnel to the remote machine. Is there a better way to do this other than putting a sleep() in. Right now I have a 10 second sleep in between the connect_to() call and the status check on the local/client stunnel TCP port. That seems to be enough time for stunnel to attept to complete the connection and kill the connection to it's local/client port so that when I check the status of it, it comes back bad. If this is the best way to do it...what is the amount of time needed for stunnel to attempt to complete it's connection to the remote machine? Thanks! Jeff

It works only if i specify > https://ipaddress:8070 This is because the default port for https is 443. If you'd configure stunnel to accept on port 443, `https://ipaddress' would work. > I have configured one client server also to accept connection on 80 > and redirect to teh 8070 of server. I want to know that is that teh > way its working . If there is a stunnel instance on the client machine accepting connections on port 80 and connecting to the web server at the https port (default or not), a user could specify `http://localhost' to connect to the web server (and the traffic between the client machine and the server would be secured). > And is it possible to implement the same in a live enviroment ,in > which teh webserver will run on different port ,but users dont need > to specify the port number . Yes. As soon as the destination port for the 'first hop' of a redirected/tunneled connection is the default port for the protocol in question, there is no need to specify the port number. The port numbers of 'intermediate hops' are configuration options for the two stunnel instances (in this case), so the user dosn't have to care about them.
