Hi again Dewen;
It sounds to me like Stunnel isn't being accessed at all. You should be seeing something in the Stunnel log window. I run Stunnel under Windows, so what I generally do is get Stunnel to listen to the loopback interface at address 127.0.0.1, or some other address within the loopback interface range. As such, if I was attempting to access it with a utility like Netcat, my basic stunnel.conf would look something like this for the client side:
debug =7
[service.name] client = yes accept = 127.0.0.1:12035 connect = destination.address:1230
Then, I would point Netcat to the listening address and port. In your case, that might be netcat 127.0.0.1:12035.
Then see if Stunnel logs your connection attempt.
Again, this is under Windows, so your mileage may vary.
Let us know how it works out for you.
Regards;
Thomas

Hi Thomas,
Thank you for your help.
here is the config file in one computer
client = yes [ncat] accept = 12035 connect = ***.***.***.***:1230
and on this computer, I run the command: cat test.file | netcat ***.***.***.***: 12035. to connect the remote server with IP( ***.***.***.***) on port 12035. I figure on stunnel will accept the port 12035 and connect to the remote server on port 1230 or I thought.
and no another remote server, I run the command netcat -l -p 1230 which means listen to the port 1230.
after I run the test, it seems on remote server didn't receive anything on the port 1230.the log file of stunnel dooesn't have any record of this communication. the last line of the log file is still "configuration successfully"
and the version of stunnel I use is 4.42
any suggests that may be wrong?

Dewen; I think I misread your post. Please forgive me, as I'm unfamiliar with the Netcat application. If you could provide some additional detail, that might be helpful.

Try redirecting Netcat to the listening port. If you need to post again, please indicate the version of Stunnel you are using, and what platform your are running it on.

And I check the log file. there is no record about the netcat. I don't know what happened. -- */Dewen Kong/* _______________________________________________ stunnel-users mailing list stunnel-users@stunnel.org <mailto:stunnel-users@stunnel.org> http://stunnel.mirt.net/mailman/listinfo/stunnel-users-- Attention: This message and all attachments are private and may contain information that is confidential and privileged.
