[Jessie-discuss] Handshake timeout - preventing DoS

[Martin Egholm Nielsen]

Hi Casey,

Trying to make my webserver (more) robust against DoS (Denial of 
Service), I've noticed that one can easily make Jessie "occupy" and 
block during handshaking. This can obviously be done by telnet'ing the 
server on the used port, and then just do anything with that telnet 
connection...

So in order to prevent this hanging there forever, flooding the server 
with open connections, it would be nice if was possible to set a timeout 
value for the handshake.

And now you say, why not just use "setSoTimeout()" from you application 
before reading anything from the socket. But that timeout value will 
then have influence on the rest of the "read"'ing that initiated the 
handshake...
