+2 votes

Does anyone know where/if I could get an ssl cerficate for postfix/dovecot that is signed and free? I have generated my own unsigned one, but some users want to use gmail to retrieve their mail and it doesn't accept unsigned certificates.

Trouble installing renewed SSL certificate with Apache

The ssl cert on my apache server have expired. It is actually a server at work - a important one as well so I'm a bit stressed at the moment.

The cert is renewed and I have received the cert files. I'm now trying to install them but I can't get it to work.

I thought it was as simple as just copying the new crt file to the server and restart apache but apache start fails.

I see this in the log:

509 certificate routines:X509_check_private_key:key values mismatch

Server: Apache 2.2.22 on Ubuntu 12.04. How does one install a renewed ssl cert? Do I need to create a new private key and ca-bundle? Please point me in the right direction.

Apache: reverse proxy, balancing and ssl client certificate authentication

I have an idea how to setup Apache for doing load balancer based on mod_proxy and mod_balance modules. But in my case the backend server requires ssl client certificate authentication and therefore the Apache Server cannot terminate the ssl connection.

I do no need http session cookie stickyness. The application is stateless. Can I somehow configure Apache as a transparent balancer?

Or I should use even another software - squid, iptables? The backend application is a web service running on Tomcat.

How do I get a valid HTTPS certificate for a box that is behind a firewall and does not have a DNS entry?

How do I get a valid certificate for a box that is behind a firewall and does not have a DNS entry?

I was looking at letsencrypt.org but currently it looks like a valid DNS entry is needed, of which I don't have.

There is nothing special about my setup, its just a box that is not directly on the internet, no DNS entry but I need HTTPS to run correctly.

How do I generate a trusted certificate base on IP or something?

How can I do that? Thanks,
