Thanks for providing this information. The Server: TreeNeWS/0.0.1 banner seems to be quite common for embedded Linux/Unix systems running on devices like Enterasys RBT-8200, 3Com WX2200 or the mentioned Juniper Trapeze.
Based on this we could add some basic Linux/Unix OS Detection.
More detailed OS detection could be possible when providing the additional output of “Unknown OS and Service Banner Reporting (OID: 1.3.6.1.4.1.25623.1.0.108441)” (like described in Call for info: Unknown OS and Service Banner Reporting) and the HTML output of a possible login page gathered via curl with a call like e.g.:
curl -i example.com -o login_page
Please make sure that the login_page file doesn’t contain any sensitive information.
