| H A D | in.h | diff 176805 Tue Mar 04 17:16:21 MST 2008 rpaulo Change the default port range for outgoing connections by introducing IPPORT_EPHEMERALFIRST and IPPORT_EPHEMERALLAST with values 10000 and 65535 respectively. The rationale behind is that it makes the attacker's life more difficult if he/she wants to guess the ephemeral port range and also lowers the probability of a port colision (described in draft-ietf-tsvwg-port-randomization-01.txt). While there, remove code duplication in in_pcbbind_setup(). Submitted by: Fernando Gont <fernando at gont.com.ar> Approved by: njl (mentor) Reviewed by: silby, bms Discussed on: freebsd-net |
