119 This option allows scripts and executables to be invoked
120 when specific URLs are requested.
122 config FEATURE_HTTPD_CONFIG_WITH_SCRIPT_INTERPR
123 bool "Enable support for running scripts through an interpreter"
125 depends on 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 FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV
134 bool "Support the REMOTE_PORT environment variable for CGI"

191 bool "Set the broadcast automatically"
195 Setting this will make ifconfig attempt to find the broadcast
196 automatically if the value '+' is used.
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 IFCONFIG and ROUTE, or enable
207 FEATURE_IFUPDOWN_IP and the various 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 FEATURE_IFUPDOWN_IP
220 Use the iproute "ip" command to implement "ifup" and "ifdown", rather
221 than the default of using the older 'ifconfig' and 'route' utilities.

235 utility or the "ifup" and "ifdown" applets will not work.
237 config FEATURE_IFUPDOWN_IFCONFIG_BUILTIN
238 bool "Use busybox ifconfig and route applets"
240 depends on IFUPDOWN && !FEATURE_IFUPDOWN_IP
244 Use the busybox iproute "ifconfig" and "route" applets to
245 implement the "ifup" and "ifdown" utilities.
247 If left disabled, you must install the full-blown ifconfig
248 and route utilities, or the "ifup" and "ifdown" applets will not
251 config FEATURE_IFUPDOWN_IPV4
252 bool "Enable support for IPv4"
256 If you want busybox to talk IPv4, leave this on.

500 same time provide full support for ICMP packets.
506 Route displays or manipulates the kernel's IP routing tables.
512 Telnet is an interface to the TELNET protocol, but is also commonly
513 used to test other simple protocols.
515 config FEATURE_TELNET_TTYPE
516 bool "Pass TERM type to remote host"
520 Setting this option will forward the TERM environment variable to the
521 remote host you are connecting to. This is useful to make sure that
522 things like ANSI colors and other control sequences behave.
524 config FEATURE_TELNET_AUTOLOGIN
525 bool "Pass USER type to remote host"
529 Setting this option will forward the USER environment variable to the
530 remote host you are connecting to. This is useful when you need to
531 log into a machine without telling the username (autologin). This
532 option enables `-a' and `-l USER' arguments.
537 select FEATURE_SYSLOG
539 A daemon for the TELNET protocol, allowing you to log onto the host
540 running the daemon. Please keep in mind that the TELNET protocol
541 sends passwords in plain text. If you can't afford the space for an
542 SSH daemon and you trust your network, you may say 'y' here. As a
543 more secure alternative, you should seriously consider installing the
544 very small Dropbear SSH daemon instead:
545 http://matt.ucc.asn.au/dropbear/dropbear.html
547 Note that for busybox telnetd to work you need several things:
548 First of all, your kernel needs:
552 Next, you need a /dev/pts directory on your root filesystem:
555 drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/
557 Next you need the pseudo terminal master multiplexer /dev/ptmx:
560 crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
562 Any /dev/ttyp[0-9]* files you may have can be removed.
563 Next, you need to mount the devpts filesystem on /dev/pts using:
565 mount -t devpts devpts /dev/pts
567 You need to be sure that Busybox has LOGIN and
568 FEATURE_SUID enabled. And finally, you should make
569 certain that Busybox has been installed setuid root:
571 chown root.root /bin/busybox
572 chmod 4755 /bin/busybox
574 with all that done, telnetd _should_ work....
577 config FEATURE_TELNETD_INETD
578 bool "Support call from inetd only"
582 Selecting this will make telnetd only callable from inetd,
583 removing the standalone support.

607 a client to transfer a file to a TFTP server.
609 config FEATURE_TFTP_BLOCKSIZE
610 bool "Enable \"blocksize\" command"
614 Allow the client to specify the desired block size for transfers.
621 Enable debug settings for tftp. This is useful if you're running
622 into problems with tftp as the protocol doesn't help you much when
623 you run into problems.
