Recently I was finding that my SSH connection to a Media Temple (dv) Centos 5 server was freezing. Creating a local config file fixed it. For anyone else suffering the same problem here's how to do it.
By taking a few simple steps with SSH, FTP and the firewall you can make your Plesk server more secure than the default configuration.
Increasingly I'm growing disillusioned with Plesk and SWsoft the company behind it. For me it is a stagnant product and a lack of competition is the root cause.
