Some scripts I wrote
This section is being moved to its own page: My scripts
- add_machine.sh - Script to be used by Samba to automatically add machine accounts to UNIX passwd. It will add machine accounts starting with an specified UID (30000 by default), so they won't be mixed with normal user accounts. Uses awk to find the next available UID.
- chunk-decode.php - CLI PHP script to decode the raw data from a HTTP connection which transfers a file using Transfer-Encoding: chunked. It is useful to restore files when all you have is a dump from tcpdump/ethereal. (Note: This script does not parse tcpdump file, it only parses the raw HTTP data sent by server. You must use some other software, like ethereal, to isolate the server-to-client data. Read the script for more info.)
- ls2html.sh - Generates HTML code from current directory listing. Useful to run as:
ls2html.sh full > index.html
