man page of the nc command has following information
-k Forces nc to stay listening for another connection after its current connection is completed. It is an error to use this option without the -l option.
nc --help output has not any information regarding to -k option.
And when I try to capture packages like
nc -kl -i 86400 -p 44444 > nc_44444.dmp
I got following error
netcat: invalid option -- 'k'
So what is the problem ? Is there any option called as "-k"
My problem is I have to capture some data from network and sometimes client application could disconnect from server port and it could reconnect again. So I don't want to get problem about disconnect/reconnect events
