--tcp-flags


--tcp-flags
other than being totally confused as to what these are.
SYN
ACK
FIN
RST
URG
PSH
The only two I understand are the ones for ALL and NONE.
Can somebody please explain what these flags mean or where I can locate info on what they mean.
Thanks,

If you want some fun reading, try RFC 793 which specifies the transmission control protocol (http://www.faqs.org/rfcs/rfc793.html).

The SYN flag is used to SYNchronize a connection - basically to set it up. FIN means there is no more data left, and RST is set to "reset" the connection.

The others are for ACKnowledgements, URGent data and PuSH which "forces" delivery of data.

I know the above is pretty simplistic, so read the RFC or other online resources for more info

Here's one I found on Google:
