I have a website built on PHP and CodeIgnitor as well as a WordPress blog and a CentOS Linux Server running Plesk Panel. The site is being attacked and daily I am fixing the damage they are doing. I have no idea how they are getting into the site, and this type of this is over my head. I am looking for someone to figure out how to get this fixed and patched before it takes down the entire site. The hackers are attacking the mail server on my server and sending out spam email, deleting files, and uploading phishing sites into folders. I have also had some database changes that I think are from them as well.

We need a linux administrator to help us deal with this: we have a ubuntu machine. The machine has a public interface and a private interface (class B). We need to set a ipsec based vpn on this machine and allow 100 users to connect via vpn. After connecting to the VPN each user should have access to: 1. A shared class C network. (lets say 192.168.5.0/24) 2. A private class C network corresponding to their user-id. e.g. user 10 should have access to : 192.168.5.0/24 and 192.168.10.0/24 user 11 should have access to 192.168.5.0/24 and 192.168.11.0/24 The vpn should be easy to set-up for end user. We do not want to distribute a config file; but only username, password (and may be a group password). Users should not be able to route traffic to subnet they are not allowed to.
