Top Forums UNIX for Advanced & Expert Users How does netcat manage the data it transfers ? Post 302349090 by wakatana on Monday 31st of August 2009 05:37:00 AM

Hi qiulang Only thing I somewhere read about netcat is:

If you want transfer file between machines you type
reciever# nc -l p 8000 > /home/user/destination
sender# nc reciever 8000 < /home/user/source
But if somebody else start to send packets to reciever:8000 they will be ignored (cause it is TCP comunucation and session has been established previous)
Maybe it will help you
