Hello,

I've found Stunnel as a potential answer to securely moving traffic between two machines.

But I'm having some difficulties configuring the software.

I've installed it on to the client machine and configured the client to connect to 127.0.0.1:8449 while the Server to which the client needs to connect is 192.168.220.72:8447

In the stunnel.conf I've set the following:

[custom]

accept = 127.0.0.1:8449

connect = 192.168.220.72:8447

cert = 220.72.cer

TIMEOUTclose = 0

Upon initializing Stunnel I get the following error:

2016.05.16 19:14:04 LOG3[main]: error queue: 140B0009: error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_file:PEM lib

2016.05.16 19:14:04 LOG3[main]: SSL_CTX_use_PrivateKey_file: 906D06C: error:0906D06C:PEM routines:PEM_read_bio:no start line

2016.05.16 19:14:04 LOG3[main]: Service [custom]: Failed to initialize SSL context

2016.05.16 19:14:04 LOG3[main]: Failed to reload the configuration file

What can be the cause?

Thanks in advance.

Best Regards,

David.
