Server Administration

I am primarily based in a Unix/Linux platform when it comes to advanced administration (Gentoo, FreeBSD, Debian).

I am currently maintaining my own web-host servers (clustered), database servers (in replication), multiple DNS servers, multiple mail servers.

I've had experience installing, configuring and maintaining the following applications (in no particular order):

• Apache Web Server - Single and Load-balancing setups
• Lighttpd Web Server - Load-balancing of static and dynamic setups
  
• Mysql Database Server - Clustering, Replication and Single
• CVS - Content Versioning
• SVN - (Sub Version) Content Versioning
• Qmail - Mail Transfer Agent
• Postfix - Mail Transfer Agent
• Courier - Mail Delivery (IMAP/POP3 and SSL IMAP/POP3)
• Jabberd - Internal/External Messaging System
• OpenLDAP - Directory Service
• SNMP - Network Node Monitoring
• SpamAssassin - Mail Filter
• Amavis - Mail Filter Wrapper
• Samba - CIFS/SMB File Server
• Rsync - Remote Syncing of Files
• Bind - DNS Server
• Bind-dlz - Bind + Mysql Implimentation
• Squirrel-mail - Web-based Mail Client
• Roundcube - Web-based Mail Client
• Webalizer - Web Statistics
• AWStats - Web Statistics
• OpenVPN - VPN Server/Client (bridging and tunneling)
• PopTop - PPTP Server for remote dial-in
• PF - Packet Filter (OpenBSD implementation on FreeBSD)
• IPTables - IP Firewalling for Linux Kernel
  

Above are the main aspects of my server administration. There are many other smaller utilities that I have maintained.

Other aspects to mention, are that I have run multiple high load gaming servers at large (500+ node) LAN, which require high maintenance to and optimisation to allow minimal latency increases as these people who play on them are picky about the quality of the playing feild when there is money involved.

Network Administration

I have intermediate experience with network setup and maintenance.

I've had experience with the following networking situations:

• BGP Routing via WIX/APE.
• DMZ instances for seperation of networks.
• Running multiple subnets over the same network.
• OpenVPN bridging of multiple remote networks together.
• Assistance in development and installation of temporary 500 node LAN Gaming network.
• Assistance in development and installation of a 200 node LAN for Wellingtons largest Internet Cafe.
• Assistance in development and installation of a 50 node LAN for Palmerston North's largest Internet Cafe (now closed).
• Development of UDP broadcasting program to allow LAN servers on remote networks to show up.
