Hi All , it's mandatory for use stunnel wich the infrastructure has client stunnel and server stunnel ??

Or I can have client stunnel vs Web server HTTPS without stunnel server , only web server https .

I newbie in stunnel , but i think is  mandatory install stunnel in both sites , that's is correct?

If possible use Squid  + stunnel  to solve the problem with host header? The application is very very old .

Thanks

The problem is the "Host: ..." header that is being sent to the remote server. You need to configure 127.0.0.1:19021 as a proxy in your app (and curl) and then have the app (curl) fetch https://ctm.omego.net

Not sure how to do that in curl, but search the curl manpage for any mentions of "proxy".

Thanks @Peter

Yes , my application not support TLS and I need the application connect using TLS , for this i using stunnel (i hope)

When I make curl -v http://127.0.0.1:19021 :

curl -v http://127.0.0.1:19201

• Rebuilt URL to: http://127.0.0.1:19201/

*   Trying 127.0.0.1...

• Connected to 127.0.0.1 (127.0.0.1) port 19201 (#0)

...

GET / HTTP/1.1 Host: 127.0.0.1:19201 User-Agent: curl/7.47.0 Accept: */*

The web ctm.omgeo.net only works in mode HTTPS , .

Hello ,

Thanks @Peter

I'm trying to configure to connect with my PC to this Public server https://ctm.omgeo.net using TLS1.2 but i don't can.

I'm need setup stunnel for old application doesn't support TLS ,

and this

...

...

application need connect with this public server to send data.

I'm using the Peter config , but nothing . I try this config :

[omgeo] client = yes accept = 127.0.0.1:19201 connect = ctm.omgeo.net:443 verify = 2 CApath = /etc/ssl/certs/

I'm using Curl to try connect  , I'm recive this error

/etc/ssl/certs# curl -v https://127.0.0.1:19201

Maybe I'm reading this wrong, but if your client application does not support TLS, then it won't speak HTTPS, it would speak plain HTTP. That's what the configuration you're using does - it tells stunnel to run in client mode, i.e. something will connect to stunnel using an unencrypted connection and stunnel will connect to a TLS server (in this case an HTTPS server).

So what happens when you try almost the same query, but with the "http" scheme instead of the "https" one?

curl -v http://127.0.0.1:19201

G'luck, Peter
