I am attempting to use stunnel to encrypt traffic between our backup client (Window2008R2) and our NetApp filer, but I’m not having any luck
We would like to use the stunnel to redirect the port 80 calls to the filer (ubfs2.buffalo.edu) to port 443.
Be design, the backup client (IBM Tivoli/TSM V6.2.4) makes a call to the Netapp over http.admin interface to tell it to create a snapshot.
The filer listens on https.admin (not http.admin), and we don’t want to turn on http.admin for security reasons.
I’ve included the stunnel.config file, hosts file, and the output below.
If anyone could give us a hand here it would be much appreciated.
We tested this config on a Mac laptop and it works just fine, so I would assume that it has something to do with Windows2008R2
Stunnel.config
debug = 7
client = yes
[snapdiff]
accept = localhost:80
connect = 128.205.5.55:443
sslVersion = all
hosts
127.0.0.1 localhost ubfs2.buffalo.edu
output
