Hi guys, i'm hoping someone can shed some light on this for me...

I'm using ncat to tunnel a port through to a webservice on a machine using
the command:

ncat -l 1444 -c "ncat xxx.xxx.xxx.xxx 1444 -o log.txt"

this works great until i try to post a large request down the tunnel, at
which point the log file suddenly stops after 512 characters (and the
request never completes)

is this a limit in ncat does anybody know? or just a limit to the amount of
data logged?

the responses are certainly bigger than 512 and come through with no
problems

Does it happen only when logging with -o, or always?
