HOST-SETUP(1) BSD General Commands Manual HOST-SETUP(1)NAMEhost-setup — System configuration setup/management utility
SYNOPSIShost-setup [-hsX]
DESCRIPTION
The host-setup is a dialog(1) (or Xdialog(1)) based utility for configur‐
ing your system. Built on the same safety and reliability of sysrc(8) to
manage changes to rc.conf(5), host-setup can also activate changes to the
system in a safe and effective manner. Functionality includes (but may
not be limited to):
- Configuring Time Zone
- Configuring Hostname/Domain
- Configuring Network Interfaces
- Configuring Default Router/Gateway
- Configuring DNS nameservers
The following options are available:
-h Print a usage message to stderr and exit.
-X Use Xdialog(1) in place of dialog(1).
-s Secure. Prompt for sudo(8) credentials (used with -X).
This utility provides either a Terminal (using dialog(1), the default) or
Graphical (using Xdialog(1), passing -X) User Interface for changing cer‐
tain system settings.
In many cases, host-setup can also be used to apply rc.conf(5) changes
made outside this utility, avoiding a reboot.
DEPENDENCIES
The following standard commands are required by host-setup:
awk(1), cat(1), chmod(1), chown(8), chsh(1), cmp(1), cp(1), date(1),
df(1), dhclient(8), dialog(1), find(1), grep(1), hostname(1), id(1),
ifconfig(8), mktemp(1), mv(1), printf(1), rm(1), route(8), sed(1), sh(1),
sleep(1), stat(1), strings(1), su(1), sudo(8), tail(1), tzsetup(8),
uname(1), which(1)
The following standard commands are optional, based on arguments passed
and situation, but enhance the abilities of host-setup:
Xdialog(1), tzdialog(8), xterm(1)FILES
/etc/defaults/rc.conf
/etc/rc.conf
/etc/rc.conf.local
EXAMPLES
Below are some simple examples of how host-setup can be used to configure
and/or manage your system.
host-setup
Launches the default console-based user interface (must be root).
sudo host-setup
Prompts for sudo(8) credentials if not already root before
launching the default console-based user interface with escalated
privileges.
sudo host-setup-X
Launches the gaphical user interface as root in a compatible X11
environment (requires appropriate DISPLAY variable).
host-setup-sX
By default, root privileges are required to make the sorts of
changes that are required during system configuration. This usually
means launching via sudo(8) as in the above example. However, when
executing from another X11 application, this utility may need to
escalate privileges to function properly. The addition of the -s
flag causes the user to be prompted with Xdialog(1) for sudo(8)
credentials.
LIMITATIONS
The host-setup utility is limited in scope to configuring basic connec‐
tivity and performing routine system tasks. It is not designed to be an
all-in-one swiss-army knife, kitchen sink, or bike shed.
Other limitations are self-imposed for safety reasons. For example,
host-setup will allow you to view and change network settings while NFS
mounts are active but will not allow you to activate new network settings
until NFS mounts are no longer active (preventing system hang).
Another self-imposed limitation is that while you are allowed to view and
change the hostname while connected via an X11-Forwarded ssh(1) session,
you are not allowed to activate the new hostname until re-executed from
either a local terminal or non-X11-Forwarded ssh(1) session (preventing
the fatal error “X11 connection rejected because of wrong
authentication”).
