Unlike web browsers, the CA root cert is not installed by default for svn clients. You would need to tell the client where to find it in order to trust the ssl cert.
Reference:
For GoDaddy signed certs, download their root certs available at:
You would need both the pem encoded gd-class2-root.crt and gd_intermediate.crt .
Then in subversion client global settings, tell it the path to the certs:
Today, on my 28th birthday, I'm finally delivering on a promise to my readers which I made about two months ago. I've on how to host a web application redundantly in a cloud environment. While it's still a bit of a rough draft, it should be a good starting point for those who haven't worked in virtualized environments before. Also, it may show some of the more experienced systems administrators a new way to do things.
The guide:
As always, if you find anything in the guide that needs improvement, I'm all ears.
Regardless of the type of hosting you're using — dedicated or cloud — it's important to take network interface security seriously. Most often, threats from the internet are the only ones mentioned. However, if you share a private network with other customers, you have just as much risk on that interface.
Many cloud providers allow you access to a private network environment where you can exchange data with other instances or other services offered by the provider. The convenience of this access comes with a price: other instances can access your instance on the private network just as easily as they could on the public interface.
Here are some security tips for your private interfaces:
Disable the private interface
This one is pretty simple. If you have only one instance or server, and you don't need to communicate privately with any other instances, just disable the interface. Remember to configure your networking scripts to leave the interface disabled after reboots.
Use packet filtering
The actual mechanism will vary based on your operating system, but filtering packets is the one of the simplest ways to secure your private interface. You can take some different approaches with them, but I find the easiest method is to allow access from your other instances and reject all other traffic.
For additional security, you can limit access based on ports as well as source IP addresses. This could prevent an attacker from having easy access to your other instances if they're able to break into one of them.
Configure your daemons to listen on the appropriate interfaces
If there are services that don't need to be listening on the private network, don't allow them to listen on your private interface. For example, MySQL might need to listen on the private interface so the web server can talk to it, but apache won't need to listen on the private interface. This reduces the profile of your instance on the private network and makes it a less likely target for attack.
Use hosts.allow and hosts.deny
Many new systems administrators forget about how handy tcpwrappers can be for limiting access. If your firewall is down in error, host.allow and hosts.deny could be an extra layer of protection. It's important to ensure that the daemons you are attempting to control are build with tcpwrappers support. Daemons like sshd support it, but apache and MySQL do not.
Encrypt all traffic on the private network
Just because it's called a «private» network doesn't mean that your traffic can traverse the network privately. You should always err on the side of caution and encrypt all traffic traversing the private network. You can use ssh tunnels, stunnel, or the built-in SSL features found in most daemons.
This also brings up an important point: you should know how your provider's private network works. Are there safeguards to prevent sniffing? Could someone else possibly ARP spoof your instance's private IP addresses? Is your private network's subnet shared among many customers?
With all of that said, it's also very important to have proper change control policies so that administrators working after you are fully aware of the security measures in place and why they are important. This will ensure that all of the administrators on your instances will understand the security of the system and they should be able to make sensible adjustments later for future functionality.
You need to disable SSL ver 2 and enable SSL ver 3 in apache for PCI compliance. Its very easy to do. Following settings will set SSL ver 3 and also disable older/unsecure cipher suite in Redhat/centos/fedora Linux server:
1. Open /etc/httpd/conf.d/ssl.conf and add or if these lines already there, edit them as per follows:
