This would allow username re-use. You *could* do it by hacking getpw*(3) and including a call to getsockname(2). I do it by building virtual machines using a hacked inetd(8) which does a getsockname(2) followed by a chroot(2) to the virtual machine. The vm needs to have ld.so and lib/* etc, etc, etc. It is great for allowing telnet access to web sites while preventing customers from peeking at each other's stuff. /* Daniel O'Callaghan */ /* HiLink Internet <http://www.hilink.com.au/>; danny@hilink.com.au */ /* FreeBSD - works hard, plays hard... danny@freebsd.org */
