Client packets , nosep !

[rOCk-MaStEr]

it prevents it for a GID i specify...

Deny client sockets to group: (socket_client)
what does it deny exactly !!!!!
i have a problem for example with Java Chat ( DigiChat )
anybody can use a lame windows prog.. WPE winsock packet editor
to edit and spoof packets..
does that protect the sockets or it will deny actually even the chat sockets !!!

Deny server sockets to group: (socket_server)
also the deny server sockets can anybody explain

and i had a problem booting with the GRSEC and found the topic but how can i boot with the 'nosep' kernel option !!
