# # For a description of the syntax of this configuration file, # see scripts/kbuild/config-language.txt. # menu "Networking Utilities" config FEATURE_IPV6 bool "Enable IPv6 support" default n help Enable IPv6 support in busybox. This adds IPv6 support in the networking applets. config VERBOSE_RESOLUTION_ERRORS bool "Verbose resolution errors" default n help Enable if you are not satisfied with simplistic "can't resolve 'hostname.com'" and want to know more. This may increase size of your executable a bit. config ARP bool "arp" default n help Manipulate the system ARP cache. config ARPING bool "arping" default n help Ping hosts by ARP packets. config DNSD bool "dnsd" default n help Small and static DNS server daemon. config ETHER_WAKE bool "ether-wake" default n help Send a magic packet to wake up sleeping machines. config FAKEIDENTD bool "fakeidentd" default n select FEATURE_SYSLOG help fakeidentd listens on the ident port and returns a predefined fake value on any query. config FTPGET bool "ftpget" default n help Retrieve a remote file via FTP. config FTPPUT bool "ftpput" default n help Store a remote file via FTP. config FEATURE_FTPGETPUT_LONG_OPTIONS bool "Enable long options in ftpget/ftpput" default n depends on GETOPT_LONG && (FTPGET || FTPPUT) help Support long options for the ftpget/ftpput applet. config HOSTNAME bool "hostname" default n help Show or set the system's host name. config HTTPD bool "httpd" default n help Serve web pages via an HTTP server. config FEATURE_HTTPD_USE_SENDFILE bool "Use sendfile system call" default n depends on HTTPD help When enabled, httpd will use the kernel sendfile() function instead of read/write loop. config FEATURE_HTTPD_RELOAD_CONFIG_SIGHUP bool "Support reloading the global config file using hup signal" default n depends on HTTPD help This option enables processing of SIGHUP to reload cached configuration settings. config FEATURE_HTTPD_SETUID bool "Enable -u option" default n depends on HTTPD help This option allows the server to run as a specific user rather than defaulting to the user that starts the server. Use of this option requires special privileges to change to a different user. config FEATURE_HTTPD_BASIC_AUTH bool "Enable Basic http Authentication" default y depends on HTTPD help Utilizes password settings from /etc/httpd.conf for basic authentication on a per url basis. config FEATURE_HTTPD_AUTH_MD5 bool "Support MD5 crypted passwords for http Authentication" default n depends on FEATURE_HTTPD_BASIC_AUTH help Enables basic per URL authentication from /etc/httpd.conf using md5 passwords. config FEATURE_HTTPD_CONFIG_WITH_MIME_TYPES bool "Support loading additional MIME types at run-time" default n depends on HTTPD help This option enables support for additional MIME types at run-time to be specified in the configuration file. config FEATURE_HTTPD_CGI bool "Support Common Gateway Interface (CGI)" default y depends on HTTPD help This option allows scripts and executables to be invoked when specific URLs are requested. config FEATURE_HTTPD_CONFIG_WITH_SCRIPT_INTERPR bool "Enable support for running scripts through an interpreter" default n depends on FEATURE_HTTPD_CGI help This option enables support for running scripts through an interpreter. Turn this on if you want PHP scripts to work properly. You need to supply an additional line in your httpd config file: *.php:/path/to/your/php config FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV bool "Support the REMOTE_PORT environment variable for CGI" default n depends on FEATURE_HTTPD_CGI help Use of this option can assist scripts in generating references that contain a unique port number. config FEATURE_HTTPD_ENCODE_URL_STR bool "Enable the -e option for shell script CGI simplification." default y depends on HTTPD help This option allows html encoding arbitrary strings for display of the browser. Output goes to stdout. For example, httpd -e "" as "<Hello World>". config FEATURE_HTTPD_ERROR_PAGES bool "Enable support for custom error pages" default n depends on HTTPD help This option allows you to define custom error pages in the configuration file instead of the default HTTP status error pages. For instance, if you add the line: E404:/path/e404.html in the config file, the server will respond the specified '/path/e404.html' file instead of the terse '404 NOT FOUND' message. config IFCONFIG bool "ifconfig" default n help Ifconfig is used to configure the kernel-resident network interfaces. config FEATURE_IFCONFIG_STATUS bool "Enable status reporting output (+7k)" default y depends on IFCONFIG help If ifconfig is called with no arguments it will display the status of the currently active interfaces. config FEATURE_IFCONFIG_SLIP bool "Enable slip-specific options \"keepalive\" and \"outfill\"" default n depends on IFCONFIG help Allow "keepalive" and "outfill" support for SLIP. If you're not planning on using serial lines, leave this unchecked. config FEATURE_IFCONFIG_MEMSTART_IOADDR_IRQ bool "Enable options \"mem_start\", \"io_addr\", and \"irq\"" default n depends on IFCONFIG help Allow the start address for shared memory, start address for I/O, and/or the interrupt line used by the specified device. config FEATURE_IFCONFIG_HW bool "Enable option \"hw\" (ether only)" default y depends on IFCONFIG help Set the hardware address of this interface, if the device driver supports this operation. Currently, we only support the 'ether' class. config FEATURE_IFCONFIG_BROADCAST_PLUS bool "Set the broadcast automatically" default n depends on IFCONFIG help Setting this will make ifconfig attempt to find the broadcast automatically if the value '+' is used. config IFUPDOWN bool "ifupdown" default n help Activate or deactivate the specified interfaces. This applet makes use of either "ifconfig" and "route" or the "ip" command to actually configure network interfaces. Therefore, you will probably also want to enable either IFCONFIG and ROUTE, or enable FEATURE_IFUPDOWN_IP and the various IP options. Of course you could use non-busybox versions of these programs, so against my better judgement (since this will surely result in plenty of support questions on the mailing list), I do not force you to enable these additional options. It is up to you to supply either "ifconfig", "route" and "run-parts" or the "ip" command, either via busybox or via standalone utilities. config IFUPDOWN_IFSTATE_PATH string "Absolute path to ifstate file" default "/var/run/ifstate" help ifupdown keeps state information in a file called ifstate. Typically it is located in /var/run/ifstate, however some distributions tend to put it in other places (debian, for example, uses /etc/network/run/ifstate). This config option defines location of ifstate. config FEATURE_IFUPDOWN_IP bool "Use ip applet" default n depends on IFUPDOWN help Use the iproute "ip" command to implement "ifup" and "ifdown", rather than the default of using the older 'ifconfig' and 'route' utilities. config FEATURE_IFUPDOWN_IP_BUILTIN bool "Use busybox ip applet" default y depends on FEATURE_IFUPDOWN_IP select IP select FEATURE_IP_ADDRESS select FEATURE_IP_LINK select FEATURE_IP_ROUTE help Use the busybox iproute "ip" applet to implement "ifupdown". If left disabled, you must install the full-blown iproute2 utility or the "ifup" and "ifdown" applets will not work. config FEATURE_IFUPDOWN_IFCONFIG_BUILTIN bool "Use busybox ifconfig and route applets" default y depends on IFUPDOWN && !FEATURE_IFUPDOWN_IP select IFCONFIG select ROUTE help Use the busybox iproute "ifconfig" and "route" applets to implement the "ifup" and "ifdown" utilities. If left disabled, you must install the full-blown ifconfig and route utilities, or the "ifup" and "ifdown" applets will not work. config FEATURE_IFUPDOWN_IPV4 bool "Enable support for IPv4" default y depends on IFUPDOWN help If you want ifup/ifdown to talk IPv4, leave this on. config FEATURE_IFUPDOWN_IPV6 bool "Enable support for IPv6" default n depends on IFUPDOWN && FEATURE_IPV6 help If you need support for IPv6, turn this option on. ### UNUSED ### config FEATURE_IFUPDOWN_IPX ### bool "Enable support for IPX" ### default n ### depends on IFUPDOWN ### help ### If this option is selected you can use busybox to work with IPX ### networks. config FEATURE_IFUPDOWN_MAPPING bool "Enable mapping support" default n depends on IFUPDOWN help This enables support for the "mapping" stanza, unless you have a weird network setup you don't need it. config FEATURE_IFUPDOWN_EXTERNAL_DHCP bool "Enable support for external dhcp clients" default n depends on IFUPDOWN help This enables support for the external dhcp clients. Clients are tried in the following order: dhcpcd, dhclient, pump and udhcpc. Otherwise, if udhcpc applet is enabled, it is used. Otherwise, ifup/ifdown will have no support for DHCP. config INETD bool "inetd" default n select FEATURE_SYSLOG help Internet superserver daemon config FEATURE_INETD_SUPPORT_BUILTIN_ECHO bool "Support echo service" default y depends on INETD help Echo received data internal inetd service config FEATURE_INETD_SUPPORT_BUILTIN_DISCARD bool "Support discard service" default y depends on INETD help Internet /dev/null internal inetd service config FEATURE_INETD_SUPPORT_BUILTIN_TIME bool "Support time service" default y depends on INETD help Return 32 bit time since 1900 internal inetd service config FEATURE_INETD_SUPPORT_BUILTIN_DAYTIME bool "Support daytime service" default y depends on INETD help Return human-readable time internal inetd service config FEATURE_INETD_SUPPORT_BUILTIN_CHARGEN bool "Support chargen service" default y depends on INETD help Familiar character generator internal inetd service config FEATURE_INETD_RPC bool "Support RPC services" default n depends on INETD select FEATURE_HAVE_RPC help Support Sun-RPC based services config IP bool "ip" default n help The "ip" applet is a TCP/IP interface configuration and routing utility. You generally don't need "ip" to use busybox with TCP/IP. config FEATURE_IP_ADDRESS bool "ip address" default y depends on IP help Address manipulation support for the "ip" applet. config FEATURE_IP_LINK bool "ip link" default y depends on IP help Configure network devices with "ip". config FEATURE_IP_ROUTE bool "ip route" default y depends on IP help Add support for routing table management to "ip". config FEATURE_IP_TUNNEL bool "ip tunnel" default n depends on IP help Add support for tunneling commands to "ip". config FEATURE_IP_RULE bool "ip rule" default n depends on IP help Add support for rule commands to "ip". config FEATURE_IP_SHORT_FORMS bool "Support short forms of ip commands." default n depends on IP help Also support short-form of ip commands: ip addr -> ipaddr ip link -> iplink ip route -> iproute ip tunnel -> iptunnel ip rule -> iprule Say N unless you desparately need the short form of the ip object commands. config IPADDR bool default y depends on FEATURE_IP_SHORT_FORMS && FEATURE_IP_ADDRESS config IPLINK bool default y depends on FEATURE_IP_SHORT_FORMS && FEATURE_IP_LINK config IPROUTE bool default y depends on FEATURE_IP_SHORT_FORMS && FEATURE_IP_ROUTE config IPTUNNEL bool default y depends on FEATURE_IP_SHORT_FORMS && FEATURE_IP_TUNNEL config IPRULE bool default y depends on FEATURE_IP_SHORT_FORMS && FEATURE_IP_RULE config IPCALC bool "ipcalc" default n help ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, and host range. config FEATURE_IPCALC_FANCY bool "Fancy IPCALC, more options, adds 1 kbyte" default y depends on IPCALC help Adds the options hostname, prefix and silent to the output of "ipcalc". config FEATURE_IPCALC_LONG_OPTIONS bool "Enable long options" default n depends on IPCALC && GETOPT_LONG help Support long options for the ipcalc applet. config NAMEIF bool "nameif" default n select FEATURE_SYSLOG help nameif is used to rename network interface by its MAC address. Renamed interfaces MUST be in the down state. It is possible to use a file (default: /etc/mactab) with list of new interface names and MACs. Maximum interface name length: IF_NAMESIZE = 16 File fields are separated by space or tab. File format: # Comment new_interface_name XX:XX:XX:XX:XX:XX config NC bool "nc" default n help A simple Unix utility which reads and writes data across network connections. config NC_SERVER bool "Netcat server options (-l)" default n depends on NC help Allow netcat to act as a server. config NC_EXTRA bool "Netcat extensions (-eiw and filename)" default n depends on NC help Add -e (support for executing the rest of the command line after making or receiving a successful connection), -i (delay interval for lines sent), -w (timeout for initial connection). config NETSTAT bool "netstat" default n help netstat prints information about the Linux networking subsystem. config FEATURE_NETSTAT_WIDE bool " Enable wide netstat output" default n depends on NETSTAT help Add support for wide columns. Useful when displaying IPv6 addresses (-W option). config NSLOOKUP bool "nslookup" default n help nslookup is a tool to query Internet name servers. config PING bool "ping" default n help ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host or gateway. config PING6 bool "ping6" default n depends on FEATURE_IPV6 && PING help This will give you a ping that can talk IPv6. config PSCAN bool "pscan" default n help Simple network port scanner. config FEATURE_FANCY_PING bool "Enable fancy ping output" default y depends on PING help Make the output from the ping applet include statistics, and at the same time provide full support for ICMP packets. config ROUTE bool "route" default n help Route displays or manipulates the kernel's IP routing tables. config SLATTACH bool "slattach" default n help slattach is a small utility to attach network interfaces to serial lines. config TELNET bool "telnet" default n help Telnet is an interface to the TELNET protocol, but is also commonly used to test other simple protocols. config FEATURE_TELNET_TTYPE bool "Pass TERM type to remote host" default y depends on TELNET help Setting this option will forward the TERM environment variable to the remote host you are connecting to. This is useful to make sure that things like ANSI colors and other control sequences behave. config FEATURE_TELNET_AUTOLOGIN bool "Pass USER type to remote host" default y depends on TELNET help Setting this option will forward the USER environment variable to the remote host you are connecting to. This is useful when you need to log into a machine without telling the username (autologin). This option enables `-a' and `-l USER' arguments. config TELNETD bool "telnetd" default n select FEATURE_SYSLOG help A daemon for the TELNET protocol, allowing you to log onto the host running the daemon. Please keep in mind that the TELNET protocol sends passwords in plain text. If you can't afford the space for an SSH daemon and you trust your network, you may say 'y' here. As a more secure alternative, you should seriously consider installing the very small Dropbear SSH daemon instead: http://matt.ucc.asn.au/dropbear/dropbear.html Note that for busybox telnetd to work you need several things: First of all, your kernel needs: UNIX98_PTYS=y DEVPTS_FS=y Next, you need a /dev/pts directory on your root filesystem: $ ls -ld /dev/pts drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/ Next you need the pseudo terminal master multiplexer /dev/ptmx: $ ls -la /dev/ptmx crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx Any /dev/ttyp[0-9]* files you may have can be removed. Next, you need to mount the devpts filesystem on /dev/pts using: mount -t devpts devpts /dev/pts You need to be sure that Busybox has LOGIN and FEATURE_SUID enabled. And finally, you should make certain that Busybox has been installed setuid root: chown root.root /bin/busybox chmod 4755 /bin/busybox with all that done, telnetd _should_ work.... config FEATURE_TELNETD_STANDALONE bool "Support standalone telnetd (not inetd only)" default n depends on TELNETD help Selecting this will make telnetd able to run standalone. config TFTP bool "tftp" default n help This enables the Trivial File Transfer Protocol client program. TFTP is usually used for simple, small transfers such as a root image for a network-enabled bootloader. config FEATURE_TFTP_GET bool "Enable \"get\" command" default y depends on TFTP help Add support for the GET command within the TFTP client. This allows a client to retrieve a file from a TFTP server. config FEATURE_TFTP_PUT bool "Enable \"put\" command" default y depends on TFTP help Add support for the PUT command within the TFTP client. This allows a client to transfer a file to a TFTP server. config FEATURE_TFTP_BLOCKSIZE bool "Enable \"blocksize\" command" default n depends on TFTP help Allow the client to specify the desired block size for transfers. config DEBUG_TFTP bool "Enable debug" default n depends on TFTP help Enable debug settings for tftp. This is useful if you're running into problems with tftp as the protocol doesn't help you much when you run into problems. config TRACEROUTE bool "traceroute" default n help Utility to trace the route of IP packets config FEATURE_TRACEROUTE_VERBOSE bool "Enable verbose output" default n depends on TRACEROUTE help Add some verbosity to traceroute. This includes amongst other things hostnames and ICMP response types. config FEATURE_TRACEROUTE_SOURCE_ROUTE bool "Enable loose source route" default n depends on TRACEROUTE help Add option to specify a loose source route gateway (8 maximum). config FEATURE_TRACEROUTE_USE_ICMP bool "Use ICMP instead of UDP" default n depends on TRACEROUTE help Add feature to allow for ICMP ECHO instead of UDP datagrams. source networking/udhcp/Config.in config VCONFIG bool "vconfig" default n help Creates, removes, and configures VLAN interfaces config WGET bool "wget" default n help wget is a utility for non-interactive download of files from HTTP, HTTPS, and FTP servers. config FEATURE_WGET_STATUSBAR bool "Enable a nifty process meter (+2k)" default y depends on WGET help Enable the transfer progress bar for wget transfers. config FEATURE_WGET_AUTHENTICATION bool "Enable HTTP authentication" default y depends on WGET help Support authenticated HTTP transfers. config FEATURE_WGET_LONG_OPTIONS bool "Enable long options" default n depends on WGET && GETOPT_LONG help Support long options for the wget applet. config ZCIP bool "zcip" default n select FEATURE_SYSLOG help ZCIP provides ZeroConf IPv4 address selection, according to RFC 3927. It's a daemon that allocates and defends a dynamically assigned address on the 169.254/16 network, requiring no system administrator. See http://www.zeroconf.org for further details, and "zcip.script" in the busybox examples. endmenu
