<p>SETNET(8) System Manager&rsquo;s Manual SETNET(8)</p>
<p style="margin-top: 1em"><b>NAME</b></p>
<p style="margin-left:6%;"><b>setnet.sh</b> &mdash;
minimalist shell script for network configuration with
dialog interface</p>
<p style="margin-top: 1em"><b>SYNOPSIS</b></p>
<p style="margin-left:19%;"><b>setnet.sh</b>
[<b>&minus;c&nbsp;</b><i>config_file</i>]
[<b>&minus;d&nbsp;</b><i>trace_file</i>] [<b>&minus;h</b>]
[<b>&minus;v</b>]</p>
<p style="margin-top: 1em"><b>DESCRIPTION</b></p>
<p style="margin-left:6%;">setnet.sh is a shell script for
network management, with a terminal user interface based on
dialog(1). It works as a wrapper around the basic tools for
the configuration of Ethernet and Wi-Fi interfaces,
including ip(8), dhclient(8), and wpa_cli(8).</p>
<p style="margin-left:6%; margin-top: 1em">setnet.sh allows
to configure static and/or DHCP-based connections to a
LAN/WLAN, and to manage the authentication to a Wi-Fi
network. At present, open (no key), WPA-Personal (WPA-PSK
and WPA2-PSK), and WPA-Enterprise (EAP/PEAP or EAP/TLS) are
supported.</p>
<p style="margin-left:6%; margin-top: 1em">setnet.sh can be
also used as a minimal interface to basic network
diagnostics tools, including ping(8), host(1),
traceroute(1), and netstat(8). It allows to show some
information about network status, including the routing
table, content of resolv.conf and nsswitch.conf, active
TCP/IP connections, running daemons, etc., and to dump those
information to a file. Support for posting a dump of network
status to websites like pastebin.com is under
development.</p>
<p style="margin-left:6%; margin-top: 1em">setnet.sh
recognises the following options:</p>
<p style="margin-top: 1em"><b>&minus;c</b>
<i>config_file</i></p>
<p style="margin-left:17%;">specify a configuration
file</p>
<p style="margin-top: 1em"><b>&minus;d</b>
<i>trace_file</i></p>
<p style="margin-left:17%;">enable dialog debug, and write
the trace to the provided trace_file</p>
<p style="margin-top: 1em"><b>&minus;h</b></p>
<p style="margin-left:17%; margin-top: 1em">print a minimal
help and exit</p>
<p style="margin-top: 1em"><b>&minus;v</b></p>
<p style="margin-left:17%; margin-top: 1em">show version
and exit</p>
<p style="margin-left:6%; margin-top: 1em">The main
setnet.sh menu allows to choose from five sections, as
described below:</p>
<p style="margin-top: 1em"><b>Setup</b></p>
<p style="margin-left:17%; margin-top: 1em">This section
allows to configure a network interface, selected from the
list of available network devices (as returned by &quot;ip
-o link&quot;). Once a device has been selected, it is
possible to choose on of the following functions</p>
<p style="margin-top: 1em"><b>View</b></p>
<p style="margin-left:26%; margin-top: 1em">View current
device configuration, i.e., MAC address, link status, IP
address, etc.</p>
<p style="margin-top: 1em"><b>WiFi</b></p>
<p style="margin-left:26%; margin-top: 1em">(available only
for wi-fi devices) Manage the association to a Wi-Fi
network. This allows to restart wpa_supplicant, to manage
the currently configured networks, to add a new network, and
to show (and modify) the configuration file used by
wpa_supplicant.</p>
<p style="margin-top: 1em"><b>Conf</b></p>
<p style="margin-left:26%; margin-top: 1em">Configure the
IP address of the device. It is possible to choose between
<i>DHCP-based</i> and <i>Static</i> IP configuration.</p>
<p style="margin-top: 1em"><b>Start</b></p>
<p style="margin-left:26%; margin-top: 1em">Bring the
interface up (using &quot;ip link set &lt;DEVNAME&gt;
up&quot;).</p>
<p style="margin-top: 1em"><b>Stop</b></p>
<p style="margin-left:26%; margin-top: 1em">Bring the
interface down (using &quot;ip link set &lt;DEVNAME&gt;
down&quot;).</p>
<p style="margin-top: 1em"><b>Restart</b></p>
<p style="margin-left:26%;">Restart the interface by
putting it first down and then up again.</p>
<p style="margin-top: 1em"><b>Info</b></p>
<p style="margin-left:17%; margin-top: 1em">This section
provides information about the current network status and
allows to perform basic diagnostic tasks. The following
functions are available:</p>
<p style="margin-top: 1em"><b>ARP</b></p>
<p style="margin-left:24%; margin-top: 1em">Show the
current ARP table</p>
<p style="margin-top: 1em"><b>Connections</b></p>
<p style="margin-left:24%;">List active network connections
by running &quot;netstat -tnp&quot;</p>
<p style="margin-top: 1em"><b>DNS</b></p>
<p style="margin-left:24%; margin-top: 1em">List the
configured DNS, by showing the &quot;nameserver&quot;
entries in <i>/etc/resolv.conf.</i></p>
<p style="margin-top: 1em"><b>Lookup</b></p>
<p style="margin-left:24%;">Perform a DNS lookup through
&quot;host &lt;HOST&gt;&quot;. If &lt;HOST&gt; is a FQDN,
the result will be the IP address(es) associated to that
domain name. If &lt;HOST&gt; is an IP address, the result is
the list of FQDNs associated to that address.</p>
<p style="margin-top: 1em"><b>Ping</b></p>
<p style="margin-left:24%; margin-top: 1em">Ping a host,
using its IP of FQDN (Fully-Qualified Domain Name) by
running &quot;ping -c 5 &lt;HOST&gt;&quot;.</p>
<p style="margin-top: 1em"><b>Resolver</b></p>
<p style="margin-left:24%;">Show the system resolver
configuration, i.e. the content of the file
<i>/etc/nsswitch.conf</i></p>
<p style="margin-top: 1em"><b>Routes</b></p>
<p style="margin-left:24%;">Show the current routing
table</p>
<p style="margin-top: 1em"><b>Services</b></p>
<p style="margin-left:24%;">Show a list of processes
(daemons) listening on TCP ports, by running &quot;netstat
-ltnp&quot;.</p>
<p style="margin-top: 1em"><b>Traceroute</b></p>
<p style="margin-left:24%;">Show the route to a given host,

<p style="margin-left:17%; margin-top: 1em">Dump
information about current network status to a file. The user
can choose which information to include from a checklist.
The support for dumping network information to web
applications like <i>pastebin</i> is currently under
development.</p>
<p style="margin-top: 1em"><b>Log</b></p>
<p style="margin-left:17%; margin-top: 1em">Show the
logfile written by setnet.sh</p>
<p style="margin-top: 1em"><b>About</b></p>
<p style="margin-left:17%; margin-top: 1em">Provide
information about copyright, contributors, and license.</p>
<p style="margin-top: 1em"><b>ENVIRONMENT</b></p>
<p style="margin-left:6%;">setnet.sh uses the following
environment variables:</p>
<p style="margin-top: 1em">WPA_FILE</p>
<p style="margin-left:17%;">The configuration file for
wpa_supplicant(1) (default to
<i>/etc/wpa_supplicant/wpa_setnet.conf</i> ).</p>
<p style="margin-top: 1em">LOGFILE</p>
<p style="margin-left:17%;">The file used by setnet.sh for
logging (default to <i>/var/log/setnet.log</i> ).</p>
<p style="margin-top: 1em">TRUNCATE_LOG</p>
<p style="margin-left:17%;">If it is set to &quot;yes&quot;
or &quot;YES&quot;, the log file is truncated when setnet.sh
starts.</p>
<p style="margin-top: 1em">WIFI_DEVICES</p>
<p style="margin-left:17%;">List of wifi devices. This list
is used only when automatic detection of wifi devices
fails.</p>
<p style="margin-left:6%; margin-top: 1em">These variables
are normally set in the setnetrc configuration file (see
<b>FILES</b> below). setnet.sh will exit if either WPA_FILE
or LOGFILE are undefined.</p>
<p style="margin-top: 1em"><b>FILES</b></p>
<p style="margin-left:6%;">setnet.sh uses a configuration
file which defines the environment variables described in
<b>ENVIRONMENT</b> above. setnet.sh looks for the following
files:</p>
<p style="margin-top: 1em"><b>&bull;</b></p>
<p style="margin-left:19%;">the <i>config_file</i> provided
through the option <b>-c</b> (if any).</p>
<p style="margin-top: 1em"><b>&bull;</b></p>
<p style="margin-left:19%;">the file <i>/etc/setnetrc</i>
(if it exists)</p>
<p style="margin-top: 1em"><b>&bull;</b></p>
<p style="margin-left:19%;">the file <i>~/.setnetrc</i> (if
it exists)</p>
<p style="margin-left:6%; margin-top: 1em">in that order.
If a <i>config_file</i> is provided, the other files are
ignored. Otherwise, if <i>~/.setnetrc</i> exists, it takes
precedence over <i>/etc/setnetrc.</i></p>
<p style="margin-top: 1em"><b>SEE ALSO</b></p>
<p style="margin-left:6%;">ip(8), dhclient(8),
wpa_supplicant(8), wpa_cli(8), netstat(8).</p>
<p style="margin-top: 1em"><b>AUTHORS</b></p>
<p style="margin-left:6%;">setnet.sh is Free Software,

<p style="margin-left:6%; margin-top: 1em">setnet.sh is

&lt;katolaz@freaknet.org&gt;</p>
<p style="margin-top: 1em"><b>BUGS</b></p>
<p style="margin-left:6%;">At present, setnet.sh can
reliably manage no more than one Wi-Fi device at a time.
This is due to the fact that the configuration file for
wpa_supplicant is defined in the environment variable
WPA_FILE. There is no limitation on the number of Ethernet
devices that setnet.sh can manage, but you should be careful
with having more than one <b>dhclient</b> processes running,
since each of them will try to add a default gateway to the
kernel routing table.</p>
<p style="margin-top: 1em"><b>SECURITY
CONSIDERATIONS</b></p>
<p style="margin-left:6%;">Configuring networking is an
administration task, and setnet.sh requires root privileges
to work properly. It is possible to allow a regular user to
run setnet.sh, e.g. by using sudo(8) or sup(1) (see
https://sup.dyne.org/ for more information about sup).</p>
<p style="margin-left:6%; margin-top: 1em">setnet.sh can
recognise if it is running under sudo(8) or sup(1), by
looking at the content of the environment variables
SUDO_UID/SUP_UID, SUDO_GID/SUP_GID, and SUDO_USER/SUP_USER.
When setnet.sh is run under sudo(8) or sup(1), some
functionalities are disabled. In particular, loading and
editing an alternate wpa_supplicant configuration file is
forbidden (and for obvious reasons, since this would in
principle allow the sudoer to edit *any* file in your
system).</p>
