comment Reverse Engineering Time Clock Protocol using Wireshark
you maybe could cause the clock to respond by actively connecting it... while having another instance of netcat listening to a range of ports (which will capture the response). it's probably required to detach netcat from the console, so one can have several instances per shell prompt.

you only need option -l when capturing the server's poll (which is ordinary being accepted by the clock's listening TCP socket) - when connecting to the clock, there's no need to listen (except there is some kind of bi-directional communication going on, which I doubt).

option -l means listening (for incoming connections). I'd assume the clock need to be connected in active mode. It also could be, that the clock only answers one single IP (so that nobody can cheat on time that easily). MAC filters are rather unlikely.

like this one can see the actual console log, instead of a hexdump. ... because one need to know how the request/response format looks like, e.g. to preg_match() the returned lines and convert them into SQL. Good luck!

comment apache : disable mod_deflate - [error] an unknown filter
... ´apachectl -t -D DUMP_MODULES´ might give a clue.

´a2dismod deflate´ should disable it globally. one can simply delete the module's .ini file as well. guess requires reading logs, to find out what exactly tries to deflate the output.
