CASE STUDIES
mail and web servers

Area of assistance: Mail and web servers

Technology introduced: Red Hat Linux 6.2, Windows NT 4.0, Exchange 5.5, Cisco 1601 Router

Problem: The client needed a public mail server capable of sending one million emails per day, Internet service for 20 stations, two public web servers, two public FTP servers, a POP3 mail server, an internal mail server, a VPN tunnel server, a firewall, and mid-level network redundancy.

Analysis: The client's needs could best be met using a combination of Red Hat Linux and Windows NT server technology.

Strategy: We installed the following:

1. A Red Hat Linux 6.2 mail server, featuring Sendmail, Procmail, wu-ftpd and DNS to keep internal traffic to mail and web servers from having to go outside and back in

2. A Red Hat Linux 6.2 web server running Red Hat Secure Web Server for two web sites and wu-ftpd

3. Two Windows NT 4.0 servers, one a primary domain controller running Exchange 5.5, the other a backup domain controller receiving replication

4. A Cisco 1601 router containing a firewall feature set with IPSEC 56, service limited static routes to the Linux servers and pre-shared key VPN (virtual private network) service.

Conclusion: The client now enjoys a powerful and secure web and mail system.
