This bug, as far as I know, only happends on GV8BAA3.253 versions and is only available on the eth0 local interface. NB: My modem is an Alcatel Speed Touch Home one, therefore Ethernet. Here are the informations about my modem: - active software version : GV8BAA3.253 - firmware : 8706 - Ip local : 10.0.0.1 I did the tests from a basic distribution around LFS kernel 2.4.16 My NMAP version is 2.54BETA30 When I run NMAP -O 10.0.0.1 then the modem reboots As far as I can see this bug only happens on GV8BAA3.253 and only in local network. The LAN is protected from the incomming packets with Firewall rules that couldn't be modified (I don't think it's possible, not with this version anyway). How to know its software version: # ftp modem_ip (default : 10.0.0.138) Connected to 10.0.01 220 Inactivity timer = 120 seconds. Use 'site idle <secs>' to change. Name (10.0.0.138:root): password : ## If you have a message like 421 Service Not Available, remote server has closed connection Login failed.
