Try playing around with the debug level and see what the difference is. You can read the included manual on what the different levels do.
From the manual:
debug = [facility.]level debugging level Level is a one of the syslog level names or numbers emerg (0), alert (1), crit (2), err (3), warning (4), notice (5), info (6), or debug (7). All logs for the specified level and all levels numerically less than it will be shown. Use debug = debug or debug = 7 for greatest debugging output. The default is notice (5). The syslog facility 'daemon' will be used unless a facility name is supplied. (Facilities are not supported on Win32.) Case is ignored for both facilities and levels. If you are still having problems you can always post your config file here and the list can take a look at what you have done and make recommendations on it. Cheers Craig

Ladies and Gentlemen
I used vnc with stunnel and it seems working. but the stunnel log on the server side records the server's IP address instead of the client address. Any suggestion to fix this?
Thanks

Hello list.
Hello's :-)
I am new to stunnel and do have some problems to get it running.
Welcome to the list :-)
The server is a WinXPSP2 behind a router. The router has port forwarding enabled for port 9999 to the stunnel server (4.21). On the same box a vnc server is running on port 5900 which I like to tunnel. Firewall is opened. The netstat -a -n shows the server listening on the desired port (9999).
My server config looks like that:
cert = stunnel.pem ;key = stunnel.pem
; Some performance tunings socket = l:TCP_NODELAY=1 socket = r:TCP_NODELAY=1
; Workaround for Eudora bug ;options = DONT_INSERT_EMPTY_FRAGMENTS
; Authentication stuff ;verify = 2 ; Don't forget to c_rehash CApath ;CApath = certs ; It's often easier to use CAfile ;CAfile = certs.pem ; Don't forget to c_rehash CRLpath ;CRLpath = crls ; Alternatively you can use CRLfile ;CRLfile = crls.pem
; Some debugging stuff useful for troubleshooting ;debug = 7 ;output = stunnel.log
; Use it for client mode ;client = yes
[pop3s] accept = 995 connect = 110
[imaps] accept = 993 connect = 143
[ssmtp] accept = 465 connect = 25
Change on server
[VNC Server] accept = 9999 connect = 5900
to
[VNC Server] accept = 9999 connect = 127.0.0.1:5900
On the server you need to specify the place where the service needs to connect to. Thus you should specify the localhost ip so that when the server receives a connect on port 9999 it directs it to the server itself.
The client side is a linux box with config setting: client = yes
Change on client
[VNC Server] accept = 5900 connect = 9999
to
[VNC Server] accept = 5900 connect = your_router_ip:9999
When connecting to the service, you need to specify the servers IP address where the connection needs to go, if you don't then stunnel won't know where to direct the traffic to.
What should happen is that you specify your connection in VNC as 127.0.0.1:5900 and then VNC will connect to stunnel that will direct the traffic to the server which will in return direct it to the VNC service on itself
Let me know if you get stuck and I will generate a config file for you. Also it is recommended that you don't use the default stunnel.pem file. Please create a new certificate on the server and client and use verify = 3 to completely secure the connection. This will prevent someone else that also has the stunnel.pem file from connecting to your server.
Let me know if you need help with the creation of the certificates. It's pretty straight forward ;-)
Cheers,
Craig
Hello Craig.
Thanks a lot - this was exactly the information needed.
Communities are living because of people like you are! The perfect answer: Friendly, with some explainations where needed and the offer to help even further.
Thanks again. Stefan
P.S.: I think I can do the pem-file by myself - I ll try tomorrow.
I turned on debugging and stunnel.log seems to be okay - no error messages.
But I am not able to get an connection.
What am I doing wrong?
