Context: 2 pentium 4 boxes; freebsd 5.4 & 6.0 I detected that remote login via "rsh" doesn't work in my boxes: e.g. # rsh uffbsd uffbsd.myd.prv: Connection refused even though I've defined the trusted hosts on each box both in $HOME/.rhost= s=20 and in /etc/hosts.equiv.=20 I've also uncommented the shell lines in /etc/inetd.conf to no avail. What should I do to enable the (mistrusted) rsh connection?
