Operating Systems
topLinux/Unix
I have built and maintained many *nix boxes over the years. My first real experience was with Solaris, but I am quite familiar with all of the various flavors now. I am a big Debian fan, they provide nice stable updates, I rarely have problems with them.
I have experience installing, configuring and maintaining many different services on *nix boxes, including MySQL, Apache, PHP, BIND, Apache, SSL, SSH, SFTP, ProFTP, Sendmail, Qmail.
I also have experience writing C++ programs for *nix. I have written an SMTP program, a service to listen for UDP packets and report problems when large numbers come in on a particular port, as well as several utility programs I just wanted to write. I have also done some programming for Linux desktop environments.
