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

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
227 standalone utilities.
229 config FEATURE_IFUPDOWN_IP
234 Use the iproute "ip" command to implement "ifup" and "ifdown", rather
235 than the default of using the older 'ifconfig' and 'route' utilities.

251 config FEATURE_IFUPDOWN_IFCONFIG_BUILTIN
252 bool "Use busybox ifconfig and route applets"
254 depends on IFUPDOWN && !FEATURE_IFUPDOWN_IP
258 Use the busybox iproute "ifconfig" and "route" applets to
259 implement the "ifup" and "ifdown" utilities.
261 If left disabled, you must install the full-blown ifconfig
262 and route utilities, or the "ifup" and "ifdown" applets will not
265 config FEATURE_IFUPDOWN_IPV4
266 bool "Enable support for IPv4"
270 If you want busybox to talk IPv4, leave this on.

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

626 config FEATURE_TFTP_BLOCKSIZE
627 bool "Enable \"blocksize\" command"
631 Allow the client to specify the desired block size for transfers.
638 Enable debug settings for tftp. This is useful if you're running
639 into problems with tftp as the protocol doesn't help you much when
640 you run into problems.
646 Utility to trace the route of IP packets
