Some Small Hacks
For lack of a better place to put these, I've come up with a listing
directory of small hacks that I've made to various things. These
are not generally production quality, and mostly comprise modifications
that I've made to NetBSD for use in my environment.
This repository is neither versioned, nor guaranteed to be at all
stable. It is more of a resting place for patches that I am working
on that I feel other people might be able to use. Once I finish
them, they will be removed and put in a more appropriate place---such
as the distribution of the software that they are patching.
I am also using this page as a solicitation for comments on code, before
I submit it for inclusion elsewhere. If you find anything here useful
and especially if you find bugs, please send email to
NetBSD uses Heimdal rather than MIT Kerberos 5 and there are some
subtle differences in the APIs. I've modified a couple of X programs
to work properly with the version of Heimdal shipped in NetBSD for
use in my environment.
So, one of the problems with xdm is that it doesn't support
krb5 authentication out of the box. This is a slightly
patched up version which does. You'll have to also make
two changes to the code in xc/config/cf, which are contained
in this patch. This code
will probably only work with Heimdal and has only been
tested on NetBSD and XFree86 4.2.0.
This is a NetBSD pkgsrc tarball containing only the pkg
for xlockmore. Just unpack it and cp it into your pkgsrc
tree and build it. It should allow you to use your krb5
passwords to unlock your screen. You can also choose to
install xlock without the setuid bit, if you are not using
I've been looking at Hesiod a little bit, and the most glaring
problem that I've found is that [unlike YP] there are no automated
tools to generate the databases. Of course, the lack of existing
documentation also proves to be an issue---but I haven't had a
chance to deal with that.
This is a very simple program that uses get*ent() to iterate
over local databases and outputs a large hesiod database.
I made an attempt to make a database which is compatible
with the examples provided in ``The
Hesiod Name Server'' by Stephen P. Dyer. There are
also some options to enable Ultrix-compatibility which I
got from talking to people that run Ultrix. The code includes a
man page, which is
provided out here for reference.
