Hi,

thanks for the feedback. I'll try to troubleshoot that. Which command
are you using? You should be able to force the use of a given engine

using the "--nsock-engine=select" parameter. Could you test it(server

and client side)?

I hadn't thought to add the extra parameter, sorry I didn't realisethis first. When I force the use of "select" it works fine; when I use"poll" it doesn't work:


C:\Users\Robert>ncat -v xxx.xxxxxx.xxx 80 --nsock-engine=select

^C

Both engines seem to work fine when listening (used telnet and Ncatwith select to send to the server):


C:\Users\Robert>ncat -lk 8080 --nsock-engine=poll
hello
world
^C
C:\Users\Robert>ncat -lk 8080 --nsock-engine=select
ping
pong
