Hi there,

Tried dropping the client and server to verify=2 and still get the same issue. Still getting this error: error=unable to get local issuer certificate:

Hi Richard

Verify=3 means stunnel server checks subject part in client certificate, so you need to put each client certificate file in your stunnel server with certain way.

Try to use verify=2, that only checks ca cert portion.

Update:

I have turned on debugging in the client side and have fund the following errors:

Hi all,

I have take over a stunnel install and all the clients certs have expired.

I have been trying for the past 2 days to get the new step up to work but no such luck.

Here is the error I get on the sever side, Linux Fedora Core 3, Stunnel 4.05:

And here is the output on the client side:

I have created the certs on both server and client according to the documents at http://www.stunnel.org/faq/openssl_stunnel_ServerClientAuth.txt.

I have the cacert.pem file on the cleint side, I have c_hashed the cert file on the server side. Do I need to out the c_hash of the server side cert on the client as well?

Is there something I have missed? Any ideas as to what I can check to see where the issue is?

I am desperate, any help would be greatly appreciated.

I didn't read anywhere in your logs the certs had expired ;).

Could you please send over the config of both your server and your client? It's probably something simple but looks like you made errors in both configs.

Jan

Hi Jan,

I have replace the keys alreay. These are new keys altogether.

Here is the configs as requested:

Server:

cert = /etc/stunnel/server.pem #chroot = /usr/local/var/run/stunnel/ # PID is created inside chroot jail pid = /tmp/stunnel.pid setuid = nobody #setgid = nogroup foreground = no

# Workaround for Eudora bug #options = DONT_INSERT_EMPTY_FRAGMENTS

# Authentication stuff verify = 333 # don't forget about c_rehash CApath # it is located inside chroot jail: #CApath = /etc/stunnel/certs # or simply use CAfile instead: CAfile = /etc/stunnel/cacert.pem

# Some debugging stuff debug = 7 output = /var/log/stunnel.log

# Use it for client mode #client = yes

# Service-level configuration

[school4] accept = XX.XXX.XXX.XXX:443 connect = 10.10.10.12:23 TIMEOUTidle = 3600

Client:

CApath=c:\stunnel #cert=c:\stunnel\traf-test.pem client = yes verify = 2 debug=7

[schools] accept = 23 connect = XX.XXXX.XX.XX:443

Thanks for the help!

K, error are a bit deferent this time.....

What should I check next? Is it possible I screwed up making the certs?

Thanks again for you continued help.

It's not the keys that are wrong, they're in the wrong places. The verify failure indicates just that: both server and client have problems verifying the authenticity of oneanother.

Now try this.

At the server side:

-change verify in '=2'

At the client side:

Make sure the client certificate is not commented out as it looks like in your config:

...

CApath=c:\stunnel #cert=c:\stunnel\traf-test.pem

Without a certificate at the client side there's no way the client will ever authenticate to your 'verify = 2' server.

Secondly; remove the 'CAPath' directive from your client configuration and add the 'CAfile = /etc/stunnel/cacert.pem' to it. Do make sure you copy the cacert.pem to your client ;).

I trust you did not include the private key of your CA in cacert.pem ;).

Let me know what happens.
