Trouble after disabling SSLv3
by Dion Kant 19 Oct '14

19 Oct '14

Dear list, I have stunnel running in a configuration where we use it to connect to a webserver over https while adding client certificates to the requests. This worked fine until recently on the (Apache) webserver SSLv3 was disabled. I installed the latest version of stunnel today (stunnel-5.07b2 <https://www.stunnel.org/downloads/beta/stunnel-5.07b2.tar.gz>) but that did not fix the problem. Now STunnel tries to negotiate a https connection using the TLSv1.2 and I found that because of this Apache does not like the content of the Host variable in the HTTP header which is different from what Apache is expectingto be. With SSLv3 this was not an issue. As a result I get a "HTTP/1.1 400 Bad Request" from the webserver. In my configuration I cannot (easily) apply some form of split DNS to get the hostname correct in the http header already from the client connecting to the stunnel service. I tested using curl sending a request through stunnel to the web server and verified that when I modified the Host field in the request header it does work. To my opinion it is stunnel setting up the HTTPS connection to the webserver and stunnel should take care of setting the correct Host field in the request header. Is there a way to let stunnel take care of setting the correct info in the HTTP header? Best regards, Dion Kant

Window not updating (win32 5.05)
by Javier 16 Oct '14

16 Oct '14

Hi, just reporting that with the latest version the window doesn't get updated when there is activity. It is static. You have to minimize to tray and restore again to view the activity, what, almost, is actually as fast as have a look to the log :/ Can anyone confirm? Regards. P.S.: happening on 2k and XP. Haven't tested any NT6 version.

Mongo Replication using Stunnel
by Danny Hernandez 12 Oct '14

12 Oct '14

Hello, I am trying to create an ssl connection between two mongodb instances both using the mongodb community version. Both instances need to communicate with one another as they need to be able to ping each other. I am getting this error when attempting to connect to Instance A from Instance B and vice versa: connect_blocking: connect <ip address>:27027: Connection refused (111) I have two conf files on each server (one for client and one for server). I am using the latest version of stunnel and the latest version of mongodb. Here are my conf files: *SERVER A* cert=/etc/stunnel/stunnel.pem key = /etc/stunnel/stunnel.pem verify = 2 CAfile = /etc/stunnel/stunnel.pem pid = /client.pid output = /var/log/stunnel4/stunnel.log debug = 7 sslVersion = all [mongo-replication] accept = 27037 connect = 127.0.0.1:27017 retry = yes* * *Server B *cert=/etc/stunnel/stunnel.pem key = /etc/stunnel/stunnel.pem verify = 2 CAfile = /etc/stunnel/stunnel.pem pid = /client.pid output = /var/log/stunnel4/stunnel.log debug = 7 sslVersion = all [mongo-replication] accept = 27027 connect = 127.0.0.1:27027 retry = yes *Client A *cert=/etc/stunnel/client.pem pid = /client.pid output = /var/log/stunnel4/client.log debug = 7 client = yes [mongo-replication] accept = 27037 connect = dbtest2:27027 retry = yes *Client B *cert=/etc/stunnel/client.pem pid = /client.pid output = /var/log/stunnel4/client.log debug = 7 client = yes [mongo-replication] accept = 27037 connect = dbtest1:27037 retry = yes Could someone please assist with troubleshooting the error?

Hi! New to this list and this product. I posted this on the Amazon forums, but I need to fix this fast, so I thought I would post it here as well. I am running stunnel 5.04 for Windows on a Windows 2012 R2 instance. I have it working with SES, but after a while it just keeps timing out.
