133 This option allows scripts and executables to be invoked
134 when specific URLs are requested.
136 config FEATURE_HTTPD_CONFIG_WITH_SCRIPT_INTERPR
137 bool "Enable support for running scripts through an interpreter"
139 depends on FEATURE_HTTPD_CGI
141 This option enables support for running scripts through an
142 interpreter. Turn this on if you want PHP scripts to work
143 properly. You need to supply an addition line in your httpd
145 *.php:/path/to/your/php
147 config FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV
148 bool "Support the REMOTE_PORT environment variable for CGI"
150 depends on FEATURE_HTTPD_CGI
152 Use of this option can assist scripts in generating
153 references that contain a unique port number.

195 config FEATURE_IFCONFIG_HW
196 bool "Enable option \"hw\" (ether only)"
200 Set the hardware address of this interface, if the device driver
201 supports this operation. Currently, we only support the 'ether'
204 config FEATURE_IFCONFIG_BROADCAST_PLUS
205 bool "Set the broadcast automatically"
209 Setting this will make ifconfig attempt to find the broadcast
210 automatically if the value '+' is used.
216 Activate or deactivate the specified interfaces. This applet makes
217 use of either "ifconfig" and "route" or the "ip" command to actually
218 configure network interfaces. Therefore, you will probably also want
219 to enable either IFCONFIG and ROUTE, or enable
220 FEATURE_IFUPDOWN_IP and the various IP options. Of
221 course you could use non-busybox versions of these programs, so
222 against my better judgement (since this will surely result in plenty
223 of support questions on the mailing list), I do not force you to
224 enable these additional options. It is up to you to supply either
225 "ifconfig", "route" and "run-parts" or the "ip" command, either
226 via busybox or via standalone utilities.
228 config FEATURE_IFUPDOWN_IP
233 Use the iproute "ip" command to implement "ifup" and "ifdown", rather
234 than the default of using the older 'ifconfig' and 'route' utilities.

251 bool "Use busybox ifconfig and route applets"
253 depends on IFUPDOWN && !FEATURE_IFUPDOWN_IP
257 Use the busybox iproute "ifconfig" and "route" applets to
258 implement the "ifup" and "ifdown" utilities.
260 If left disabled, you must install the full-blown ifconfig
261 and route utilities, or the "ifup" and "ifdown" applets will not
264 config FEATURE_IFUPDOWN_IPV4
265 bool "Enable support for IPv4"
269 If you want ifup/ifdown to talk IPv4, leave this on.

293 a weird network setup you don't need it.
295 config FEATURE_IFUPDOWN_EXTERNAL_DHCP
296 bool "Enable support for external dhcp clients"
300 This enables support for the external dhcp clients. Clients are
301 tried in the following order: dhcpcd, dhclient, pump and udhcpc.
302 Otherwise, if udhcpc applet is enabled, it is used.
303 Otherwise, ifup/ifdown will have no support for DHCP.

506 nslookup is a tool to query Internet name servers.
512 ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to
513 elicit an ICMP ECHO_RESPONSE from a host or gateway.
518 depends on FEATURE_IPV6 && PING
520 This will give you a ping that can talk IPv6.
522 config FEATURE_FANCY_PING
523 bool "Enable fancy ping output"
527 Make the output from the ping applet include statistics, and at the
528 same time provide full support for ICMP packets.
534 Route displays or manipulates the kernel's IP routing tables.
540 Telnet is an interface to the TELNET protocol, but is also commonly
541 used to test other simple protocols.
543 config FEATURE_TELNET_TTYPE
544 bool "Pass TERM type to remote host"
548 Setting this option will forward the TERM environment variable to the
549 remote host you are connecting to. This is useful to make sure that
550 things like ANSI colors and other control sequences behave.
552 config FEATURE_TELNET_AUTOLOGIN
553 bool "Pass USER type to remote host"
557 Setting this option will forward the USER environment variable to the
558 remote host you are connecting to. This is useful when you need to
559 log into a machine without telling the username (autologin). This
560 option enables `-a' and `-l USER' arguments.

567 A daemon for the TELNET protocol, allowing you to log onto the host
568 running the daemon. Please keep in mind that the TELNET protocol
569 sends passwords in plain text. If you can't afford the space for an
570 SSH daemon and you trust your network, you may say 'y' here. As a
571 more secure alternative, you should seriously consider installing the
572 very small Dropbear SSH daemon instead:
573 http://matt.ucc.asn.au/dropbear/dropbear.html
575 Note that for busybox telnetd to work you need several things:
576 First of all, your kernel needs:
580 Next, you need a /dev/pts directory on your root filesystem:
583 drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/
585 Next you need the pseudo terminal master multiplexer /dev/ptmx:
588 crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
590 Any /dev/ttyp[0-9]* files you may have can be removed.
591 Next, you need to mount the devpts filesystem on /dev/pts using:
593 mount -t devpts devpts /dev/pts
595 You need to be sure that Busybox has LOGIN and
596 FEATURE_SUID enabled. And finally, you should make
597 certain that Busybox has been installed setuid root:
599 chown root.root /bin/busybox
600 chmod 4755 /bin/busybox
602 with all that done, telnetd _should_ work....
605 config FEATURE_TELNETD_STANDALONE
606 bool "Support standalone telnetd (not inetd only)"
610 Selecting this will make telnetd able to run standalone.
616 This enables the Trivial File Transfer Protocol client program. TFTP
617 is usually used for simple, small transfers such as a root image
618 for a network-enabled bootloader.
