If you are attempting to use WICReset, iWIC or the Debian equivalent utilities via a protected network such as a school, college, etc… then the following information should help you (or your IT support team) to create the temporary access rules required to enable the utility to work.
Server/IP: resetters.com / 18.104.22.168
- 23457 (TCP) for reset key authentication and functionality
- 80 (TCP/HTTP) for Database and RSS feed updates
If you intend to use the utility for network discovery of printers (not recommended for any reset or firmware downgrade functions – Use a USB connection instead!) then you will need to open the following ports on your computers own firewall to allow discovery of any networked printers.
- 3289 (UDP/ENPC)
- 161 (UDP/SNMP)
- 515 (TCP/LPD)
IMPORTANT: Security is still essential and on a maintained network such as a school (or even your own systems) we wouldn’t recommend leaving these ports open indefinitely. Instead use temporary access/rules or ones that can be enabled/disabled as required by a sysadmin.
