At QUT Library we use Stunnel to encrypt SIP2 (ie. book borrowing) traffic from
the self-checkout machines through to the Alma library services platform (as
per https://developers.exlibrisgroup.com/alma/integrations/stunnel/ )
Our self-checkout machines run Windows 10 and are allowed limited internet
access to two hosts (cloud.fetechgroup.com and ap01.alma.exlibrisgroup.com) via
our institution's Squid proxy and I have our current WinHTTP proxy settings:
Proxy Server(s) : wproxy.qut.edu.au:3128
Bypass List : *.qut.edu.au
The proxy server settings are set for all protocols (HTTP, HTTPS, secure and
FTP) and I've confirmed that web browser and the FE Technologies software is
routing via wproxy.qut.edu.au. However Stunnel is still trying to connect to
Alma directly. Our stunnel.conf is as follows (just FYI, the FE Tech software
points to 127.0.0.1:5001 as our library services platform address):
[KG_Self-Checkout]
key = client.pem
cert = client.pem
client = yes
accept = 127.0.0.1:5001
connect = ap01.alma.exlibrisgroup.com:6443
TIMEOUTclose = 0
TIMEOUTconnect = 200
TIMEOUTidle = 86400
sslVersion = TLSv1.2
Is there a way to force Stunnel to either respect the WinHTTP settings or
configure it to route traffic to wproxy.qut.edu.au:3128 before initiating the
connect = hostname:port?
I did try protocolHost as follows, but I'm probably misunderstanding how it
works https://www.stunnel.org/static/stunnel.html#SERVICE-LEVEL-OPTIONS
[KG_Self-Checkout]
key = client.pem
cert = client.pem
client = yes
accept = 127.0.0.1:5001
connect = wproxy.qut.edu.au:3128
protocolHost = ap01.alma.exlibrisgroup.com:6443
TIMEOUTclose = 0
TIMEOUTconnect = 200
TIMEOUTidle = 86400
sslVersion = TLSv1.2
Any advice or assistance gratefully accepted, and apologies if this is a silly
question - I'm just a librarian trying to make this thing work.
Thanks,
