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

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.

248 utility or the "ifup" and "ifdown" applets will not work.
250 config FEATURE_IFUPDOWN_IFCONFIG_BUILTIN
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 busybox to talk IPv4, leave this on.

495 nslookup is a tool to query Internet name servers.
501 ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to
502 elicit an ICMP ECHO_RESPONSE from a host or gateway.
507 depends on FEATURE_IPV6 && PING
509 This will give you a ping that can talk IPv6.
511 config FEATURE_FANCY_PING
512 bool "Enable fancy ping output"
516 Make the output from the ping applet include statistics, and at the
517 same time provide full support for ICMP packets.
523 Route displays or manipulates the kernel's IP routing tables.
529 Telnet is an interface to the TELNET protocol, but is also commonly
530 used to test other simple protocols.
532 config FEATURE_TELNET_TTYPE
533 bool "Pass TERM type to remote host"
537 Setting this option will forward the TERM environment variable to the
538 remote host you are connecting to. This is useful to make sure that
539 things like ANSI colors and other control sequences behave.
541 config FEATURE_TELNET_AUTOLOGIN
542 bool "Pass USER type to remote host"
546 Setting this option will forward the USER environment variable to the
547 remote host you are connecting to. This is useful when you need to
548 log into a machine without telling the username (autologin). This
549 option enables `-a' and `-l USER' arguments.
554 select FEATURE_SYSLOG
556 A daemon for the TELNET protocol, allowing you to log onto the host
557 running the daemon. Please keep in mind that the TELNET protocol
558 sends passwords in plain text. If you can't afford the space for an
559 SSH daemon and you trust your network, you may say 'y' here. As a
560 more secure alternative, you should seriously consider installing the
561 very small Dropbear SSH daemon instead:
562 http://matt.ucc.asn.au/dropbear/dropbear.html
564 Note that for busybox telnetd to work you need several things:
565 First of all, your kernel needs:
569 Next, you need a /dev/pts directory on your root filesystem:
572 drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/
574 Next you need the pseudo terminal master multiplexer /dev/ptmx:
577 crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
579 Any /dev/ttyp[0-9]* files you may have can be removed.
580 Next, you need to mount the devpts filesystem on /dev/pts using:
582 mount -t devpts devpts /dev/pts
584 You need to be sure that Busybox has LOGIN and
585 FEATURE_SUID enabled. And finally, you should make
586 certain that Busybox has been installed setuid root:
588 chown root.root /bin/busybox
589 chmod 4755 /bin/busybox
591 with all that done, telnetd _should_ work....
594 config FEATURE_TELNETD_STANDALONE
595 bool "Support standalone telnetd (not inetd only)"
599 Selecting this will make telnetd able to run standalone.

623 a client to transfer a file to a TFTP server.
625 config FEATURE_TFTP_BLOCKSIZE
626 bool "Enable \"blocksize\" command"
630 Allow the client to specify the desired block size for transfers.
637 Enable debug settings for tftp. This is useful if you're running
638 into problems with tftp as the protocol doesn't help you much when
639 you run into problems.
645 Utility to trace the route of IP packets
647 config FEATURE_TRACEROUTE_VERBOSE
