101 Utilizes password settings from /etc/httpd.conf for basic
102 authentication on a per url basis.
104 config FEATURE_HTTPD_AUTH_MD5
105 bool "Support MD5 crypted passwords for http Authentication"
107 depends on FEATURE_HTTPD_BASIC_AUTH
109 Enables basic per URL authentication from /etc/httpd.conf
112 config FEATURE_HTTPD_CONFIG_WITH_MIME_TYPES
113 bool "Support loading additional MIME types at run-time"
117 This option enables support for additional MIME types at
118 run-time to be specified in the configuration file.
120 config FEATURE_HTTPD_CGI
121 bool "Support Common Gateway Interface (CGI)"
125 This option allows scripts and executables to be invoked
126 when specific URLs are requested.
128 config FEATURE_HTTPD_CONFIG_WITH_SCRIPT_INTERPR
129 bool "Enable support for running scripts through an interpreter"
131 depends on FEATURE_HTTPD_CGI
133 This option enables support for running scripts through an
134 interpreter. Turn this on if you want PHP scripts to work
135 properly. You need to supply an addition line in your httpd
137 *.php:/path/to/your/php
139 config FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV
140 bool "Support the REMOTE_PORT environment variable for CGI"
142 depends on FEATURE_HTTPD_CGI
144 Use of this option can assist scripts in generating
145 references that contain a unique port number.
147 config FEATURE_HTTPD_ENCODE_URL_STR
148 bool "Enable the -e option for shell script CGI simplification."
152 This option allows html encoding arbitrary

161 Ifconfig is used to configure the kernel-resident network interfaces.
163 config FEATURE_IFCONFIG_STATUS
164 bool "Enable status reporting output (+7k)"
168 If ifconfig is called with no arguments it will display the status
169 of the currently active interfaces.
171 config FEATURE_IFCONFIG_SLIP
172 bool "Enable slip-specific options \"keepalive\" and \"outfill\""
176 Allow "keepalive" and "outfill" support for SLIP. If you're not
177 planning on using serial lines, leave this unchecked.
179 config FEATURE_IFCONFIG_MEMSTART_IOADDR_IRQ
180 bool "Enable options \"mem_start\", \"io_addr\", and \"irq\""

193 supports this operation. Currently, we only support the 'ether'
196 config FEATURE_IFCONFIG_BROADCAST_PLUS
197 bool "Set the broadcast automatically"
201 Setting this will make ifconfig attempt to find the broadcast
202 automatically if the value '+' is used.
209 Activate or deactivate the specified interfaces. This applet makes
210 use of either "ifconfig" and "route" or the "ip" command to actually
211 configure network interfaces. Therefore, you will probably also want
212 to enable either IFCONFIG and ROUTE, or enable
213 FEATURE_IFUPDOWN_IP and the various IP options. Of
214 course you could use non-busybox versions of these programs, so
215 against my better judgement (since this will surely result in plenty
216 of support questions on the mailing list), I do not force you to
217 enable these additional options. It is up to you to supply either
218 "ifconfig" and "route" or the "ip" command, either via busybox or via
219 standalone utilities.
221 config FEATURE_IFUPDOWN_IP
226 Use the iproute "ip" command to implement "ifup" and "ifdown", rather
227 than the default of using the older 'ifconfig' and 'route' utilities.
229 config FEATURE_IFUPDOWN_IP_BUILTIN
230 bool "Use busybox ip applet"
232 depends on FEATURE_IFUPDOWN_IP
234 select FEATURE_IP_ADDRESS
235 select FEATURE_IP_LINK
236 select FEATURE_IP_ROUTE
238 Use the busybox iproute "ip" applet to implement "ifupdown".
240 If left disabled, you must install the full-blown iproute2
241 utility or the "ifup" and "ifdown" applets will not work.
243 config FEATURE_IFUPDOWN_IFCONFIG_BUILTIN
244 bool "Use busybox ifconfig and route applets"
246 depends on IFUPDOWN && !FEATURE_IFUPDOWN_IP
250 Use the busybox iproute "ifconfig" and "route" applets to
251 implement the "ifup" and "ifdown" utilities.
253 If left disabled, you must install the full-blown ifconfig
254 and route utilities, or the "ifup" and "ifdown" applets will not
257 config FEATURE_IFUPDOWN_IPV4
258 bool "Enable support for IPv4"
262 If you want busybox to talk IPv4, leave this on.
264 config FEATURE_IFUPDOWN_IPV6

272 bool "Enable support for IPX"
276 If this option is selected you can use busybox to work with IPX
279 config FEATURE_IFUPDOWN_MAPPING

333 depends on FEATURE_HAVE_RPC
335 Support Sun-RPC based services
341 The "ip" applet is a TCP/IP interface configuration and routing
342 utility. You generally don't need "ip" to use busybox with

467 Allow netcat to act as a server.
470 bool "Netcat extensions (-eiw and filename)"
474 Add -e (support for executing the rest of the command line after
475 making or receiving a successful connection), -i (delay interval for
476 lines sent), -w (timeout for initial connection).
482 netstat prints information about the Linux networking subsystem.
488 nslookup is a tool to query Internet name servers.

495 elicit an ICMP ECHO_RESPONSE from a host or gateway.
497 config FEATURE_FANCY_PING
498 bool "Enable fancy ping output"
502 Make the output from the ping applet include statistics, and at the
503 same time provide full support for ICMP packets.
508 depends on FEATURE_IPV6
510 This will give you a ping that can talk IPv6.
512 config FEATURE_FANCY_PING6
513 bool "Enable fancy ping6 output"
517 Make the output from the ping6 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.
606 This enables the Trivial File Transfer Protocol client program. TFTP
607 is usually used for simple, small transfers such as a root image
608 for a network-enabled bootloader.
610 config FEATURE_TFTP_GET
611 bool "Enable \"get\" command"
615 Add support for the GET command within the TFTP client. This allows
616 a client to retrieve a file from a TFTP server.

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.
