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

133 depends on CONFIG_FEATURE_HTTPD_CGI
135 This option enables support for running scripts through an

163 Ifconfig is used to configure the kernel-resident network interfaces.
165 config CONFIG_FEATURE_IFCONFIG_STATUS
166 bool "Enable status reporting output (+7k)"

203 Setting this will make ifconfig attempt to find the broadcast
204 automatically if the value '+' is used.
206 config CONFIG_IFUPDOWN
209 select CONFIG_RUN_PARTS
211 Activate or deactivate the specified interfaces. This applet makes
212 use of either "ifconfig" and "route" or the "ip" command to actually
213 configure network interfaces. Therefore, you will probably also want
214 to enable either CONFIG_IFCONFIG and CONFIG_ROUTE, or enable
215 CONFIG_FEATURE_IFUPDOWN_IP and the various CONFIG_IP options. Of
216 course you could use non-busybox versions of these programs, so
217 against my better judgement (since this will surely result in plenty
218 of support questions on the mailing list), I do not force you to
219 enable these additional options. It is up to you to supply either
220 "ifconfig" and "route" or the "ip" command, either via busybox or via
221 standalone utilities.
223 config CONFIG_FEATURE_IFUPDOWN_IP
226 depends on CONFIG_IFUPDOWN
228 Use the iproute "ip" command to implement "ifup" and "ifdown", rather

237 select CONFIG_FEATURE_IP_LINK
238 select CONFIG_FEATURE_IP_ROUTE
240 Use the busybox iproute "ip" applet to implement "ifupdown".
242 If leave this disabled, you must install the full-blown iproute2
243 utility or the "ifup" and "ifdown" applets will not work.
245 config CONFIG_FEATURE_IFUPDOWN_IP_BUILTIN
246 bool "Use busybox ifconfig and route applets"
248 depends on CONFIG_IFUPDOWN && !CONFIG_FEATURE_IFUPDOWN_IP
249 select CONFIG_IFCONFIG
252 Use the busybox iproute "ifconfig" and "route" applets to
253 implement the "ifup" and "ifdown" utilities.
255 If leave this disabled, you must install the full-blown ifconfig
256 and route utilities, or the "ifup" and "ifdown" applets will not

465 making or receiving a successful connection), -i (delay interval for
466 lines sent), -w (timeout for initial connection).
468 config CONFIG_NETSTAT
472 netstat prints information about the Linux networking subsystem.
474 config CONFIG_NSLOOKUP
478 nslookup is a tool to query Internet name servers.
484 ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to
485 elicit an ICMP ECHO_RESPONSE from a host or gateway.
487 config CONFIG_FEATURE_FANCY_PING
488 bool "Enable fancy ping output"
490 depends on CONFIG_PING
492 Make the output from the ping applet include statistics, and at the

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

710 ZCIP provides ZeroConf IPv4 address selection, according to RFC 3927.
711 It's a daemon that allocates and defends a dynamically assigned
712 address on the 169.254/16 network, requiring no system administrator.
714 See http://www.zeroconf.org for further details, and "zcip.script"
