71 config CONFIG_FEATURE_HTTPD_WITHOUT_INETD
72 bool "Support using httpd as a daemon (not from inetd)"
74 depends on CONFIG_HTTPD
76 This option enables uid and port options for the httpd applet,
77 and eliminates the need to be called from the inetd server daemon.

132 depends on CONFIG_FEATURE_HTTPD_CGI
134 This option enables support for running scripts through an
135 interpreter. Turn this on if you want PHP scripts to work

140 config CONFIG_FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV
141 bool "Support the REMOTE_PORT environment variable for CGI"

156 "<Hello World>".
158 config CONFIG_IFCONFIG
162 Ifconfig is used to configure the kernel-resident network interfaces.
164 config CONFIG_FEATURE_IFCONFIG_STATUS
165 bool "Enable status reporting output (+7k)"
167 depends on CONFIG_IFCONFIG
169 If ifconfig is called with no arguments it will display the status
170 of the currently active interfaces.

173 bool "Enable slip-specific options \"keepalive\" and \"outfill\""
175 depends on CONFIG_IFCONFIG

194 supports this operation. Currently, we only support the 'ether'
197 config CONFIG_FEATURE_IFCONFIG_BROADCAST_PLUS
198 bool "Set the broadcast automatically"
200 depends on CONFIG_IFCONFIG
202 Setting this will make ifconfig attempt to find the broadcast
203 automatically if the value '+' is used.
205 config CONFIG_IFUPDOWN
208 select CONFIG_RUN_PARTS
210 Activate or deactivate the specified interfaces. This applet makes
211 use of either "ifconfig" and "route" or the "ip" command to actually
212 configure network interfaces. Therefore, you will probably also want
213 to enable either CONFIG_IFCONFIG and CONFIG_ROUTE, or enable
214 CONFIG_FEATURE_IFUPDOWN_IP and the various CONFIG_IP options. Of
215 course you could use non-busybox versions of these programs, so
216 against my better judgement (since this will surely result in plenty
217 of support questions on the mailing list), I do not force you to
218 enable these additional options. It is up to you to supply either
219 "ifconfig" and "route" or the "ip" command, either via busybox or via
220 standalone utilities.
222 config CONFIG_FEATURE_IFUPDOWN_IP
225 depends on CONFIG_IFUPDOWN
227 Use the iproute "ip" command to implement "ifup" and "ifdown", rather
228 than the default of using the older 'ifconfig' and 'route' utilities.

233 depends on CONFIG_FEATURE_IFUPDOWN_IP
235 select CONFIG_FEATURE_IP_ADDRESS
236 select CONFIG_FEATURE_IP_LINK
237 select CONFIG_FEATURE_IP_ROUTE
239 Use the busybox iproute "ip" applet to implement "ifupdown".
241 If leave this disabled, you must install the full-blown iproute2
242 utility or the "ifup" and "ifdown" applets will not work.
244 config CONFIG_FEATURE_IFUPDOWN_IP_BUILTIN
245 bool "Use busybox ifconfig and route applets"
247 depends on CONFIG_IFUPDOWN && !CONFIG_FEATURE_IFUPDOWN_IP
248 select CONFIG_IFCONFIG
251 Use the busybox iproute "ifconfig" and "route" applets to
252 implement the "ifup" and "ifdown" utilities.
254 If leave this disabled, you must install the full-blown ifconfig
255 and route utilities, or the "ifup" and "ifdown" applets will not
258 config CONFIG_FEATURE_IFUPDOWN_IPV4
259 bool "Enable support for IPv4"
261 depends on CONFIG_IFUPDOWN
263 If you want busybox to talk IPv4, leave this on.

266 bool "Enable support for IPv6"
268 depends on CONFIG_IFUPDOWN && CONFIG_FEATURE_IPV6
270 If you need support for IPv6, turn this option on.

462 making or receiving a successful connection), -i (delay interval for
463 lines sent), -w (timeout for initial connection).
465 config CONFIG_NETSTAT
469 netstat prints information about the Linux networking subsystem.
471 config CONFIG_NSLOOKUP
475 nslookup is a tool to query Internet name servers.
481 ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to
482 elicit an ICMP ECHO_RESPONSE from a host or gateway.
484 config CONFIG_FEATURE_FANCY_PING
485 bool "Enable fancy ping output"
487 depends on CONFIG_PING
489 Make the output from the ping applet include statistics, and at the
490 same time provide full support for ICMP packets.
495 depends on CONFIG_FEATURE_IPV6

518 used to test other simple protocols.
520 config CONFIG_FEATURE_TELNET_TTYPE
521 bool "Pass TERM type to remote host"
523 depends on CONFIG_TELNET
525 Setting this option will forward the TERM environment variable to the
526 remote host you are connecting to. This is useful to make sure that
527 things like ANSI colors and other control sequences behave.
529 config CONFIG_FEATURE_TELNET_AUTOLOGIN
530 bool "Pass USER type to remote host"
532 depends on CONFIG_TELNET
534 Setting this option will forward the USER environment variable to the
535 remote host you are connecting to. This is useful when you need to
536 log into a machine without telling the username (autologin). This
537 option enables `-a' and `-l USER' arguments.
539 config CONFIG_TELNETD
543 A daemon for the TELNET protocol, allowing you to log onto the host
544 running the daemon. Please keep in mind that the TELNET protocol
545 sends passwords in plain text. If you can't afford the space for an
546 SSH daemon and you trust your network, you may say 'y' here. As a
547 more secure alternative, you should seriously consider installing the
548 very small Dropbear SSH daemon instead:
549 http://matt.ucc.asn.au/dropbear/dropbear.html
551 Note that for busybox telnetd to work you need several things:
552 First of all, your kernel needs:
556 Next, you need a /dev/pts directory on your root filesystem:
559 drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/
561 Next you need the pseudo terminal master multiplexer /dev/ptmx:
564 crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
566 Any /dev/ttyp[0-9]* files you may have can be removed.
567 Next, you need to mount the devpts filesystem on /dev/pts using:
569 mount -t devpts devpts /dev/pts
571 You need to be sure that Busybox has CONFIG_LOGIN and
572 CONFIG_FEATURE_SUID enabled. And finally, you should make
573 certain that Busybox has been installed setuid root:
575 chown root.root /bin/busybox
576 chmod 4755 /bin/busybox
578 with all that done, telnetd _should_ work....
581 config CONFIG_FEATURE_TELNETD_INETD
582 bool "Support call from inetd only"
584 depends on CONFIG_TELNETD
586 Selecting this will make telnetd only callable from inetd,
587 removing the standalone support.
593 This enables the Trivial File Transfer Protocol client program. TFTP
594 is usually used for simple, small transfers such as a root image
595 for a network-enabled bootloader.
597 config CONFIG_FEATURE_TFTP_GET
598 bool "Enable \"get\" command"

603 a client to retrieve a file from a TFTP server.
605 config CONFIG_FEATURE_TFTP_PUT
606 bool "Enable \"put\" command"
608 depends on CONFIG_TFTP

616 depends on CONFIG_TFTP
618 Allow the client to specify the desired block size for transfers.

633 Utility to trace the route of IP packets
635 config CONFIG_FEATURE_TRACEROUTE_VERBOSE
636 bool "Enable verbose output"
638 depends on CONFIG_TRACEROUTE

697 depends on CONFIG_WGET && CONFIG_GETOPT_LONG
699 Support long options for the wget applet.
705 ZCIP provides ZeroConf IPv4 address selection, according to RFC 3927.
706 It's a daemon that allocates and defends a dynamically assigned
707 address on the 169.254/16 network, requiring no system administrator.
709 See http://www.zeroconf.org for further details, and "zcip.script"
710 in the busybox examples.
