I got an HP4000tn with version: ROM G.07.02, EEPROM G.07.03 and this nmap scan does not crash it. I'm using nmap 2.3BETA14.

I discovered this while trying to diagnose a connection problem we were having with a printer. I've verified this with at least the following versions of JetDirect: Firmware Rev. : A.08.06 Firmware Rev. : G.08.03 Firmware Rev. : G.07.17 Firmware Rev. : G.07.03 I haven't been able to establish the exact communications causing the lockup; someone with more experience than I should check this out. Any network accessable printer can be put out of service with a simple nmap -sT -PT HP.printer.tcp.ip A power cycle is required for reset. My apologies if i have the wrong email address. (there is no Submit a Bug instructions on the securityfocus site). HP have no bug reporting facilities either... thanks, Paul Knowles. email: Paul.Knowles () unifr ch finger me at pexppc33.unifr.ch for more contact information
