I'm able to get the "Invalid term!" message if i echo anything with 0xFF bytes in it. Wireshark, amap and amapcrap were entertaining at best in terms of fuzzing it. Anyone try talking to the service with Scapy yet? I'm just starting to read up on it...

I'm curious if this has anything to do with things like eBPF

The example from the cheat sheet should be a good start to not get that message...

I can make it return ...
"a towel!"
and
"O"
" towel!"
(two consecutive reads)
...using the exact same input data. Granted, I had to send a bad QD.
And yes, it is a binary protocol.

Ouch! My program was buggy. I was truncating stuff. Fixed program and now I get some interesting output. Still trying to figure out what the codes mean though.

I'm using C and sockets to send and recv.

It seems like all I can get is "Invalid term!", is there meant to be another message?

Yes. Perhaps you are sending ASCII instead of bytes?

Very tricky! ;)

If the server replies immediately with no results (port closes, no data from server), does that indicate an error?

Does it means BrownOS just segfaults on errors?
