Hi List Members! I'm proud to announce the first update to my host-setup utility (a dialog(1)-based host configurator for FreeBSD). The following changes have been made: - fixed bug where /etc/resolv.conf would be created with 0600 permissions - fixed bug when switching from one default gateway to NO default gateway - fixed typo in the title of netmask prompt and ifconfig options dialog - fixed bug that prevented entry of netmask if no netmask is configured You can get the updated version here: http://druidbsd.sourceforge.net/download/host-setup.txt or http://druidbsd.sourceforge.net/download/host-setup.gz or http://druidbsd.sourceforge.net/ For those not familiar with my host-setup(1) utility, it is a 2,500+ line shell script that utilizes the dialog(1) utility to walk the system administrator through setting up their TimeZone, Hostname, Network Interfaces, Default Gateway, and DNS. Our custom FreeBSD installer sets this script as the root login shell, making it very easy for field engineers to quickly get a system on the network without having to use the command-line (and without having to reboot either). Underneath the hood - behind the system of prompts and dialogs - this script manages both the contents of /etc/rc.conf, /etc/resolv.conf, and others as well as utilizing ifconfig(8), route(8), and many other tools to avoid requiring a reboot, prompting you if you would like to make the new changes effective when values are changed from their active settings. Here's the patch to show the details: --- host-setup.3_0 2011-02-10 19:14:30.000000000 -0800 +++ host-setup 2011-04-21 13:38:58.000000000 -0700 @@ -2,12 +2,12 @@ # -*- tab-width: 4 -*- ;; Emacs # vi: set tabstop=4 :: Vi/ViM # -# Revision: 3.0 +# Revision: 3.1 # Created: September 21st, 2010 -# Last Modified: December 6th, 2010 +# Last Modified: April 21st, 2011 ############################################################ COPYRIGHT # -# Devin Teske (c)2006-2010.
