SSL tunnel problem

[new_user 2]

EDIT: SOLVED (SEE BELOW)

 

I am having trouble making an ssl tunnel using the stunnel client. This is using ubuntu linux. I get a message that ssl server needs certificate:

 

:~/Downloads/AirVPN(5)$ stunnel AirVPN_CH-Virginis_SSL-443.ssl
Clients allowed=500
stunnel 4.53 on x86_64-pc-linux-gnu platform
Compiled with OpenSSL 1.0.1c 10 May 2012
Running  with OpenSSL 1.0.1e 11 Feb 2013
Update OpenSSL shared libraries or rebuild stunnel
Threading:PTHREAD SSL:+ENGINE+OCSP Auth:LIBWRAP Sockets:POLL+IPv6
Reading configuration from descriptor 3
Compression not enabled
PRNG seeded successfully
Initializing inetd mode configuration
Section stunnel: SSL server needs a certificate
str_stats: 2 block(s), 10 data byte(s), 116 control byte(s)

 

****************************

 

SOLUTION

 

On Ubuntu 13.10, this problem is caused because stunnel is linked to stunnel3.

 

To solve the problem, instead use the command run

 

stunnel4 <sslconfigfilename>.ssl

 

and runs fine.
