Daring to challenge the will of the almighty Leviam00se, Gerhard Mehldau
(mehldau@photogrammetrie.de) had the courage to say:
: Hello world,
: I am trying to use NIS groups in my /etc/hosts.equiv file,
: but they don't seem to be working. Since there is no man-
: page for hosts.equiv, I thought I'd ask if someone knows
: more about this -- is it a bug, a missing feature, or am I
: overlooking something simple?
: This is with FreeBSD 2.1.0-RELEASE, and NIS works just
: fine with the passwd and group files.
: Gerhard
You can use netgroups (careful, that's netgroups, not groups) with
/etc/hosts.equiv (and /etc/hosts.lpd, and /.rhosts, and anything else
that uses the ruserok() function). There is one bug to be aware of
in FreeBSD 2.1.0-RELEASE, which is that rlogind/rshd will core dump
if /etc/netgroup doesn't exist and NIS is turned on. To turn on NIS
netgroup support, you can do either:
# rm -f /etc/netgroup
# touch /etc/netgroup (i.e. create an empty /etc/netgroup file)
or
# rm -f /etc/netgroup
# echo + > /etc/netgroup (create a file with just a + in it)
This should be documented in the netgroup(5) man page. Note that
/etc/netgroup does not exist by default: you must create it after
you install FreeBSD.
You'll also need to make sure that you have access to the netgroup,
netgroup.byname and netgroup.byhost maps through NIS. Once you do
this, you can add things like:
+@equiv-hosts
to your /etc/hosts.equiv file.
