It is meant to be POSIX-compliant, and has been +tested with bash, busybox, dash, ksh, mksh, posh, and yash. It is +still to be considered beta software, so you should use it AT YOUR OWN +RISK, but it is already fully functional. + +=== LICENSE === + +setnet is Free Software, and can be used and distributed under the +terms of the GNU General Public License, either version 3 of the +licence or, at your option, any later version. + +Please see the file LICENSE for more information + +=== DEPENDENCIES === + +In order to run setset, you MUST satisfy this (relatively small) set +of dependencies: + + - a posix-compliant shell (bash, busybox, dash, ksh, mksh, posh, and + yash have been tested) + + - dialog (version 1.2 tested, but it should work with previous + versions as well) + + - dhcp-client (for dhclient, tested with isc-dhcp-client) + + - iproute2 (for ip) + + - wireless-tools (for iwconfig, currently required for interface + identification) + +Most of those tools might already be installed in your system anyway. +In particular, setnet uses: + + - dialog: to provide a minimal Text-based User Interface, + - ip: to configure network interfaces and get information about them, + - dhclient: for DHCP-based IP configuration + - iwconfig: to check whether a network device is a wifi adapter + +In order to use the full set of functionalities provided by setnet, +you MIGHT also need the following packages: + + - wpa_supplicant (for wifi configuration) + + - net-tools (for netstat, to gather information about network status) + + - iputils-ping (for ping) + + - bind9-nost (for host, used to check DNS configuration) + + - traceroute (to trace the route between your host and any other host + in the Internet) + +Again, most of them should be already installed in your system anyway. + +=== USAGE === + +setnet is installed under /usr/sbin/setnet.sh. If invoked with "-h", +it provides a list of supported options: + +$ ./setnet.sh -h +Usage: setnet.sh [OPTION] +Options: + -c cfg_file Load configuration from cfg_file. + -v Print version number and exit. + -h Show this help. +$ + +If the argument "-c" is specified, setnet will use the provided +configuration file.

The following configuration variables should be +defined in setnetrc: + + + - WPA_FILE + This is the file configuration file used by wpa_supplicant. + + - LOGNAME + This is the file used for logging. + + - TRUNCATE_LOG + if equal to "yes", the log file will be truncated when setnet + starts + + +=== root vs. mortal users === + +Networking is an amdinistration task, and as such should be performed +by the host administrator, i.e., the user with UID 0 (normally called +"root").

It is meant to be POSIX-compliant, and has been +tested with bash, busybox, dash, ksh, mksh, posh, and yash. It is +still to be considered beta software, so you should use it AT YOUR OWN +RISK, but it is already fully functional. + +=== LICENSE === + +setnet is Free Software, and can be used and distributed under the +terms of the GNU General Public License, either version 3 of the +licence or, at your option, any later version. + +Please see the file LICENSE for more information + +=== DEPENDENCIES === + +In order to run setset, you MUST satisfy this (relatively small) set +of dependencies: + + - a posix-compliant shell (bash, busybox, dash, ksh, mksh, posh, and + yash have been tested) + + - dialog (version 1.2 tested, but it should work with previous + versions as well) + + - dhcp-client (for dhclient, tested with isc-dhcp-client) + + - iproute2 (for ip) + + - wireless-tools (for iwconfig, currently required for interface + identification) + +Most of those tools might already be installed in your system anyway. +In particular, setnet uses: + + - dialog: to provide a minimal Text-based User Interface, + - ip: to configure network interfaces and get information about them, + - dhclient: for DHCP-based IP configuration + - iwconfig: to check whether a network device is a wifi adapter + +In order to use the full set of functionalities provided by setnet, +you MIGHT also need the following packages: + + - wpa_supplicant (for wifi configuration) + + - net-tools (for netstat, to gather information about network status) + + - iputils-ping (for ping) + + - bind9-nost (for host, used to check DNS configuration) + + - traceroute (to trace the route between your host and any other host + in the Internet) + +Again, most of them should be already installed in your system anyway. + +=== USAGE === + +setnet is installed under /usr/sbin/setnet.sh. If invoked with "-h", +it provides a list of supported options: + +$ ./setnet.sh -h +Usage: setnet.sh [OPTION] +Options: + -c cfg_file Load configuration from cfg_file. + -v Print version number and exit. + -h Show this help. +$ + +If the argument "-c" is specified, setnet will use the provided +configuration file. Otherwise, it will look for its configuration file +in one of the following locations: + + - /etc/setnetrc + - ~/.setnetrc + +in the given order. The following configuration variables should be +defined in setnetrc: + + + - WPA_FILE + This is the file configuration file used by wpa_supplicant. + + - LOGNAME + This is the file used for logging. + + - TRUNCATE_LOG + if equal to "yes", the log file will be truncated when setnet + starts + + +=== root vs. mortal users === + +Networking is an amdinistration task, and as such should be performed +by the host administrator, i.e., the user with UID 0 (normally called +"root").
