Warning: OSScan results may be unreliable because we could not find at least 1 open and 1 closed port
Device type: general purpose
Running (JUST GUESSING): Linux 4.X|3.X (90%)
OS CPE: cpe:/o:linux:linux_kernel:4.4 cpe:/o:linux:linux_kernel:3
OS fingerprint not ideal because: Missing a closed TCP port so results incomplete
Aggressive OS guesses: Linux 4.4 (90%), Linux 3.10 - 3.12 (89%), Linux 4.9 (89%), Linux 3.10 - 3.16 (86%), Linux 4.0 (86%)
No exact OS matches for host (test conditions non-ideal).
