So, on to my next "make the scans cleaner" project.
How would one deal with snmp coming back with something like:
9.1.1.13.0 = Hex-STRING: 00 00 00 00 00 00 00 00 00 00 00
It's not a null, from near as I can tell... that is, isnull(var[1])
and isnull(string(var[1])) both are not true. doing a string(var[1])
gives:
..........
it displays 10 periods which are not the ascii values (an artifact of
the terminal perhaps?). I can get the length of the string (yay!) but
am leery of just matching on a length (although, honestly, in this
case, it's probably not gong to return any false negatives). How
might one go about matching that? Forgive me, while I have a CS
degree, my programming is kinda rusty (like 7 years since I was
programming every day) and the documentation I can find is complete
on what it covers, but I don't think it covers this :)

The best book on programming for the layman is "Alice in Wonderland";
but that's because it's the best book on anything for the layman.
