Backup (archive) your Gmail IMAP folders.
Copies an entire hierarchy of mailboxes from the named POP3/IMAP/etc. source to the named destination. Mailboxes are created on the destination as needed. NOTE: The 'mailutil' is Washington's University 'mailutil' (apt-get install uw-mailutils). More examples $ mailutil transfer {imap.gmail.com/ssl/user=you@gmail.com}INBOX Gmail/ ; mailutil check imap.gmail.com/ssl/user=you@gmail.com}\[Gmail\]/Spam If you use the utility in the first, append -v|-d flag(s) to the end the commands above (man mailutil).

Real time duplication of Apache app traffic to a second server
This takes the stream created by apache requests containing jsp and funnels them to another server. I'm using this for simulating real time traffic. The nice command gives ssh maximum CPU cycles, awk & grep strip out everything served by apache. Putting parallel on curl is important because curl is synchronous and waits for the response. Yes, I thought about using wget but it didn't seem any easier. Also, if you figure out how to run this in the background let me know. Every time I background it it stops. If you have multiple front end servers just run multiple instances of this.

Efficient remote forensic disk acquisition gpg-crypted for multiple recipients
Acquires a bit-by-bit data image, gzip-compresses it on multiple cores (pigz) and encrypts the data for multiple recipients (gpg -e -r). It finally sends it off to a remote machine.
