OpenBSD

Il progetto OpenBSD è sistema operativo UNIX basato su 4.4 BSD ed è gratuito e multipiattaforma. OpenBSD supporta l’emulazione binaria di molti programmi da Solaris, FreeBSD, Linux, BSD/OS, SunOS e HP-UX.

In ssh(1), tightened permissions on pty(4) when the “tty” group does not exist.
Be coherent in the way arp(8) and ndp(8) display local entries, use “l” flag to distinguish them; skip broadcast entries (are not real arp(4) entries).
