Computer heretic, IT professional, tinkerer & aspiring mad sea captain. Programming, hacking, and kicking it old school since '94.
About Me
I'm a junior senior computer heretic, IT professional, web guy, tinkerer, bad
programmer, and aspiring mad sea captain. Aargh, computers are but a
fallback til me vessle's seaworthy again!
I'm a big fan of the Unix / Linux world and spend a lot of my time inside of a terminal window. As a compulsive scriptor I enjoy automating computing tasks of all shapes and sizes.
My professional experience is primarily in support, security, system administration, and development operations for web and email hosting services. Although, I also dabble with front and back end web development and offensive cyber security.

- PASSWORD: (none, leave empty)
- PORT: 21
Feel free to browse my files there! You can also upload files to the write-only incoming directory in order to send them to me. Useful for files larger than what can normlly be sent via Email. If the incoming dir is missing you'll need to follow the steps in the reload.txt file to manually reload it. The incoming dir will be automatically archived shortly after anything is uploaded to it.
If you use FTPS you'll need to ignore the certificate warning when connecting. The ProFTPd server is using a certificate issued under a different domain name than ftp.bluesquare23.sh. However, your connection should still be encrypted. You can use my public PGP key to encrypt any files before sending them if for some reason you're limited to only using plain old FTP and you'd like to maintain encryption.
