122 config CONFIG_FEATURE_HTTPD_CONFIG_WITH_SCRIPT_INTERPR
123 bool "Enable support for running scripts through an interpreter"
125 depends on CONFIG_FEATURE_HTTPD_CGI
127 This option enables support for running scripts through an
128 interpreter. Turn this on if you want PHP scripts to work
129 properly. You need to supply an addition line in your httpd
131 *.php:/path/to/your/php
133 config CONFIG_FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV
134 bool "Support the REMOTE_PORT environment variable for CGI"

139 references that contain a unique port number.
141 config CONFIG_FEATURE_HTTPD_ENCODE_URL_STR
142 bool "Enable the -e option for shell script CGI simplification."
144 depends on CONFIG_HTTPD
146 This option allows html encoding arbitrary
147 strings for display of the browser. Output goes to stdout.
148 For example, httpd -e "<Hello World>" as

151 config CONFIG_IFCONFIG
155 Ifconfig is used to configure the kernel-resident network interfaces.
157 config CONFIG_FEATURE_IFCONFIG_STATUS
158 bool "Enable status reporting output (+7k)"
160 depends on CONFIG_IFCONFIG

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

224 bool "Use busybox ip applet"
226 depends on CONFIG_FEATURE_IFUPDOWN_IP
228 select CONFIG_FEATURE_IP_ADDRESS
229 select CONFIG_FEATURE_IP_LINK
230 select CONFIG_FEATURE_IP_ROUTE
232 Use the busybox iproute "ip" applet to implement "ifupdown".
234 If leave this disabled, you must install the full-blown iproute2
235 utility or the "ifup" and "ifdown" applets will not work.
237 config CONFIG_FEATURE_IFUPDOWN_IP_BUILTIN
238 bool "Use busybox ifconfig and route applets"
240 depends on CONFIG_IFUPDOWN && !CONFIG_FEATURE_IFUPDOWN_IP
241 select CONFIG_IFCONFIG
244 Use the busybox iproute "ifconfig" and "route" applets to
245 implement the "ifup" and "ifdown" utilities.
247 If leave this disabled, you must install the full-blown ifconfig
248 and route utilities, or the "ifup" and "ifdown" applets will not

459 ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to
460 elicit an ICMP ECHO_RESPONSE from a host or gateway.
462 config CONFIG_FEATURE_FANCY_PING
463 bool "Enable fancy ping output"
465 depends on CONFIG_PING
467 Make the output from the ping applet include statistics, and at the
468 same time provide full support for ICMP packets.
473 depends on CONFIG_FEATURE_IPV6
475 This will give you a ping that can talk IPv6.
477 config CONFIG_FEATURE_FANCY_PING6
478 bool "Enable fancy ping6 output"
480 depends on CONFIG_PING6
482 Make the output from the ping6 applet include statistics, and at the
483 same time provide full support for ICMP packets.
489 Route displays or manipulates the kernel's IP routing tables.
495 Telnet is an interface to the TELNET protocol, but is also commonly
496 used to test other simple protocols.
498 config CONFIG_FEATURE_TELNET_TTYPE
499 bool "Pass TERM type to remote host"
501 depends on CONFIG_TELNET
503 Setting this option will forward the TERM environment variable to the
504 remote host you are connecting to. This is useful to make sure that
505 things like ANSI colors and other control sequences behave.
507 config CONFIG_FEATURE_TELNET_AUTOLOGIN
508 bool "Pass USER type to remote host"
510 depends on CONFIG_TELNET
512 Setting this option will forward the USER environment variable to the
513 remote host you are connecting to. This is useful when you need to
514 log into a machine without telling the username (autologin). This
515 option enables `-a' and `-l USER' arguments.
517 config CONFIG_TELNETD
521 A daemon for the TELNET protocol, allowing you to log onto the host
522 running the daemon. Please keep in mind that the TELNET protocol
523 sends passwords in plain text. If you can't afford the space for an
524 SSH daemon and you trust your network, you may say 'y' here. As a
525 more secure alternative, you should seriously consider installing the
526 very small Dropbear SSH daemon instead:
527 http://matt.ucc.asn.au/dropbear/dropbear.html
529 Note that for busybox telnetd to work you need several things:
530 First of all, your kernel needs:
534 Next, you need a /dev/pts directory on your root filesystem:
537 drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/
539 Next you need the pseudo terminal master multiplexer /dev/ptmx:
542 crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
544 Any /dev/ttyp[0-9]* files you may have can be removed.
545 Next, you need to mount the devpts filesystem on /dev/pts using:
547 mount -t devpts devpts /dev/pts
549 You need to be sure that Busybox has CONFIG_LOGIN and
550 CONFIG_FEATURE_SUID enabled. And finally, you should make
551 certain that Busybox has been installed setuid root:
553 chown root.root /bin/busybox
554 chmod 4755 /bin/busybox
556 with all that done, telnetd _should_ work....
559 config CONFIG_FEATURE_TELNETD_INETD
560 bool "Support call from inetd only"
562 depends on CONFIG_TELNETD
564 Selecting this will make telnetd only callable from inetd,
565 removing the standalone support.
571 This enables the Trivial File Transfer Protocol client program. TFTP
572 is usually used for simple, small transfers such as a root image
573 for a network-enabled bootloader.
575 config CONFIG_FEATURE_TFTP_GET
576 bool "Enable \"get\" command"
