# # For a description of the syntax of this configuration file, # see scripts/kbuild/config-language.txt. # menu "Networking Utilities" config CONFIG_FEATURE_IPV6 bool "Enable IPv6 support" default n help Enable IPv6 support to busybox. This makes applets that talk IP able to work with IPv6. config CONFIG_ARPING bool "arping" default n help Ping hosts by ARP packets config CONFIG_FTPGET bool "ftpget" default n help Retrieve a remote file via FTP. config CONFIG_FTPPUT bool "ftpput" default n help Store a remote file via FTP. config CONFIG_HOSTNAME bool "hostname" default n help Show or set the system's host name config CONFIG_HTTPD bool "httpd" default n help Serve web pages via an HTTP server. config CONFIG_FEATURE_HTTPD_USAGE_FROM_INETD_ONLY bool " Support using httpd only from inetd" default n depends on CONFIG_HTTPD help This option disables uid and port options for the httpd applet but requires inetd server daemon. config CONFIG_FEATURE_HTTPD_BASIC_AUTH bool " Enable Basic http Authentication" default y depends on CONFIG_HTTPD help Utilizes password settings from /etc/httpd.conf for basic authentication on a per url basis. config CONFIG_FEATURE_HTTPD_AUTH_MD5 bool " Support MD5 crypted passwords for http Authentication" default n depends on CONFIG_FEATURE_HTTPD_BASIC_AUTH help Enables basic per url authentication from /etc/httpd.conf using md5 passwords. if !CONFIG_FEATURE_HTTPD_USAGE_FROM_INETD_ONLY config CONFIG_FEATURE_HTTPD_RELOAD_CONFIG_SIGHUP bool " Support reloading the global config file using hup signal" default n depends on CONFIG_HTTPD help This option enables processing of SIGHUP to reload cached configuration settings. config CONFIG_FEATURE_HTTPD_SETUID bool " Enable support -u option" default n depends on CONFIG_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. endif config CONFIG_FEATURE_HTTPD_CONFIG_WITH_MIME_TYPES bool " Support loading additional MIME types at run-time" default n depends on CONFIG_HTTPD help This option enables support for additional MIME types at run-time to be specified in the configuration file. config CONFIG_FEATURE_HTTPD_CGI bool " Support Common Gateway Interface (CGI)" default y depends on CONFIG_HTTPD help This option allows scripts and executables to be invoked when specific urls are requested. config CONFIG_FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV bool " Support the REMOTE_PORT environment variable for CGI" default n depends on CONFIG_FEATURE_HTTPD_CGI help Use of this option can assist scripts in generating references that contain a unique port number. config CONFIG_FEATURE_HTTPD_ENCODE_URL_STR bool " Enable the -e option for shell script CGI simplification." default y depends on CONFIG_HTTPD help After set, this option allows html encoding arbitrary strings for display of the browser. Output goes to stdout. For example, httpd -e "" as "<Hello World>". config CONFIG_IFCONFIG bool "ifconfig" default n help Ifconfig is used to configure the kernel-resident network interfaces. config CONFIG_FEATURE_IFCONFIG_STATUS bool " Enable status reporting output (+7k)" default y depends on CONFIG_IFCONFIG help If ifconfig is called with no arguments it will display the status of the currently active interfaces. config CONFIG_FEATURE_IFCONFIG_SLIP bool " Enable slip-specific options \"keepalive\" and \"outfill\"" default n depends on CONFIG_IFCONFIG help Allow "keepalive" and "outfill" support for SLIP. If you're not planning on using serial lines, leave this unchecked. config CONFIG_FEATURE_IFCONFIG_MEMSTART_IOADDR_IRQ bool " Enable options \"mem_start\", \"io_addr\", and \"irq\"" default n depends on CONFIG_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 CONFIG_FEATURE_IFCONFIG_HW bool " Enable option \"hw\" (ether only)" default y depends on CONFIG_IFCONFIG help Set the hardware address of this interface, if the device driver supports this operation. Currently, we only support the 'ether' class. config CONFIG_FEATURE_IFCONFIG_BROADCAST_PLUS bool " Set the broadcast automatically" default n depends on CONFIG_IFCONFIG help Setting this will make ifconfig attempt to find the broadcast automatically if the value '+' is used. config 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 CONFIG_IFCONFIG and CONFIG_ROUTE, or enable CONFIG_FEATURE_IFUPDOWN_IP and the various CONFIG_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" and "route" or the "ip" command, either via busybox or via standalone utilities. config CONFIG_FEATURE_IFUPDOWN_IP bool " Use ip applet" default n depends on CONFIG_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 CONFIG_FEATURE_IFUPDOWN_IP_BUILTIN bool " Use busybox ip applet" default y depends on CONFIG_FEATURE_IFUPDOWN_IP select CONFIG_IP select CONFIG_FEATURE_IP_ADDRESS select CONFIG_FEATURE_IP_LINK select CONFIG_FEATURE_IP_ROUTE help Use the busybox iproute "ip" applet to implement "ifupdown". If leave this disabled, you must install the full-blown iproute2 utility or the "ifup" and "ifdown" applets will not work. config CONFIG_FEATURE_IFUPDOWN_IP_BUILTIN bool " Use busybox ifconfig and route applets" default y depends on CONFIG_IFUPDOWN && !CONFIG_FEATURE_IFUPDOWN_IP select CONFIG_IFCONFIG select CONFIG_ROUTE help Use the busybox iproute "ifconfig" and "route" applets to implement the "ifup" and "ifdown" utilities. If leave this disabled, you must install the full-blown ifconfig and route utilities, or the "ifup" and "ifdown" applets will not work. config CONFIG_FEATURE_IFUPDOWN_IPV4 bool " Enable support for IPv4" default y depends on CONFIG_IFUPDOWN help If you want busybox to talk IPv4, leave this on. config CONFIG_FEATURE_IFUPDOWN_IPV6 bool " Enable support for IPv6" default n depends on CONFIG_IFUPDOWN help If you need support for IPv6, turn this option on. config CONFIG_FEATURE_IFUPDOWN_IPX bool " Enable support for IPX" default n depends on CONFIG_IFUPDOWN help If this option is selected you can use busybox to work with IPX networks. config CONFIG_FEATURE_IFUPDOWN_MAPPING bool " Enable mapping support" default n depends on CONFIG_IFUPDOWN help This enables support for the "mapping" stanza, unless you have a weird network setup you don't need it. config CONFIG_INETD bool "inetd" default n help Internet superserver daemon config CONFIG_FEATURE_INETD_SUPPORT_BILTIN_ECHO bool " Support echo service" default y depends on CONFIG_INETD help Echo received data internal inetd service config CONFIG_FEATURE_INETD_SUPPORT_BILTIN_DISCARD bool " Support discard service" default y depends on CONFIG_INETD help Internet /dev/null internal inetd service config CONFIG_FEATURE_INETD_SUPPORT_BILTIN_TIME bool " Support time service" default y depends on CONFIG_INETD help Return 32 bit time since 1900 internal inetd service config CONFIG_FEATURE_INETD_SUPPORT_BILTIN_DAYTIME bool " Support daytime service" default y depends on CONFIG_INETD help Return human-readable time internal inetd service config CONFIG_FEATURE_INETD_SUPPORT_BILTIN_CHARGEN bool " Support chargen service" default y depends on CONFIG_INETD help Familiar character generator internal inetd service config 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. if CONFIG_IP && CONFIG_IPADDR config CONFIG_FEATURE_IP_ADDRESS default y comment " address (forced enabled for ipaddr)" endif if ! (CONFIG_IP && CONFIG_IPADDR) config CONFIG_FEATURE_IP_ADDRESS bool " address" default y depends on CONFIG_IP help Address manipulation support for the "ip" applet. endif if CONFIG_IP && CONFIG_IPLINK config CONFIG_FEATURE_IP_LINK default y comment " link (forced enabled for iplink)" endif if !(CONFIG_IP && CONFIG_IPLINK) config CONFIG_FEATURE_IP_LINK bool " link" default y depends on CONFIG_IP help Configure network devices with "ip". endif if CONFIG_IP && CONFIG_IPROUTE config CONFIG_FEATURE_IP_ROUTE default y comment " route (forced enabled for iproute)" endif if !(CONFIG_IP && CONFIG_IPROUTE) config CONFIG_FEATURE_IP_ROUTE bool " route" default y depends on CONFIG_IP help Add support for routing table management to "ip". endif if CONFIG_IP && CONFIG_IPTUNNEL config CONFIG_FEATURE_IP_TUNNEL default y comment " tunnel (forced enabled for iptunnel)" endif if !(CONFIG_IP && CONFIG_IPTUNNEL) config CONFIG_FEATURE_IP_TUNNEL bool " tunnel" default n depends on CONFIG_IP help Add support for tunneling commands to "ip". endif config CONFIG_IPCALC bool "ipcalc" default n help ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, and host range. config CONFIG_FEATURE_IPCALC_FANCY bool " Fancy IPCALC, more options, adds 1 kbyte" default y depends on CONFIG_IPCALC help Adds the options hostname, prefix and silent to the output of "ipcalc". config CONFIG_IPADDR bool "ipaddr" default n help Equivalent to selecting address support to "ip", above. config CONFIG_IPLINK bool "iplink" default n help Equivalent to selecting link support to "ip", above. config CONFIG_IPROUTE bool "iproute" default n help Equivalent to selecting route support to "ip", above. config CONFIG_IPTUNNEL bool "iptunnel" default n help Equivalent to selecting tunnel support to "ip", above. config CONFIG_NAMEIF bool "nameif" default n 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 CONFIG_NC bool "nc" default n help A simple Unix utility which reads and writes data across network connections. config CONFIG_NETSTAT bool "netstat" default n help netstat prints information about the Linux networking subsystem. config CONFIG_NSLOOKUP bool "nslookup" default n help nslookup is a tool to query Internet name servers. config 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 CONFIG_FEATURE_FANCY_PING bool " Enable fancy ping output" default y depends on CONFIG_PING help Make the output from the ping applet include statistics, and at the same time provide full support for ICMP packets. config CONFIG_PING6 bool "ping6" default n depends on CONFIG_FEATURE_IPV6 help This will give you a ping that can talk IPv6. config CONFIG_FEATURE_FANCY_PING6 bool " Enable fancy ping6 output" default y depends on CONFIG_PING6 help Make the output from the ping6 applet include statistics, and at the same time provide full support for ICMP packets. config CONFIG_ROUTE bool "route" default n help Route displays or manipulates the kernel's IP routing tables. config 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 CONFIG_FEATURE_TELNET_TTYPE bool " Pass TERM type to remote host" default y depends on CONFIG_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 CONFIG_FEATURE_TELNET_AUTOLOGIN bool " Pass USER type to remote host" default y depends on CONFIG_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 CONFIG_TELNETD bool "telnetd" default n 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: CONFIG_UNIX98_PTYS=y CONFIG_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 CONFIG_LOGIN and CONFIG_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 CONFIG_FEATURE_TELNETD_INETD bool " Support call from inetd only" default n depends on CONFIG_TELNETD help Selecting this will make telnetd only callable from inetd, removing the standalone support. config 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 CONFIG_FEATURE_TFTP_GET bool " Enable \"get\" command" default y depends on CONFIG_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 CONFIG_FEATURE_TFTP_PUT bool " Enable \"put\" command" default y depends on CONFIG_TFTP help Add support for the PUT command within the TFTP client.
