"Firefox" user-agent triggers IDS alerts

[Stephane Chazelas]

Hiya,

I can see this tool does some "curl --user-agent Firefox http://static.die.net/earth/mollweide/1600.jpg"

That does trigger an alert with some network intrusion detection systems because the "Firefox" user agent has been known to be associated with trojan malware (see http://doc.emergingthreats.net/bin/view/Main/2007868 for instance).

It would probably be better to use a specific user agent like "Real-time Sunlight Wallpaper/0.4.2", or leave curl's default.
