It's been more than 20 years since I used HP VMS (VAX), but can you do
something like this:
or if that doesn't work:
see the output and verify what you have. For my Cygwin x64 environment, it
says this (stock configuration):
$ stunnel -version
stunnel 5.09 on x86_64-unknown-cygwin platform
Compiled/running with OpenSSL 1.0.1k 8 Jan 2015
Threading:PTHREAD Sockets:POLL,IPv6 TLS:ENGINE,OCSP,PSK,SNI Auth:LIBWRAP
debug = daemon.notice
RNDbytes = 64
RNDfile = /dev/urandom
RNDoverwrite = yes
ciphers = HIGH:MEDIUM:+3DES:+DH:!aNULL:!SSLv2
curve = prime256v1
options = NO_SSLv2
options = NO_SSLv3
sessionCacheSize = 1000
sessionCacheTimeout = 300 seconds
stack = 65536 bytes
TIMEOUTbusy = 300 seconds
TIMEOUTclose = 60 seconds
TIMEOUTconnect = 10 seconds
TIMEOUTidle = 43200 seconds
verify = none
What I would do is to dumb this down and first see if you can get a stunnel
client/server communication on the same box (using localhost or 127.0.0.1).
I would use iperf to just send dummy data (iperf client and iperf server).
Once that works, then move it up to using your network. If you need some
example config files, I can provide that. What I did is to use iperf client
connect to port 5000, then stunnel client listening on port 5000 and
connect to port 6000, then stunnel server listening on port 6000 and
connect to port 7000, and iperf server listening on port 7000. Since
they're non-privileged ports, you don't need admin access.
Are you using certificates? I think you need to generate the stunnel.pem
file, and I did it (using cygwin/MinGW/Linux) using these commands below.
Information stolen/modified from here:
Create a self-signed key as follows:
openssl genrsa -out key.pem 2048
openssl req -new -x509 -key key.pem -out cert.pem -days 1095
now put in the info pertinent to your organization.
then run this command:
cat key.pem cert.pem >> stunnel.pem
I don't know if you can do that with VMS, some parameters may have to be
tweaked and changed to forward-slashes (as typical in VMS). I also saw the
logging statement commented out, have you tried uncommenting those two
lines (logging verbosity and log file)?
