8 config BUSYBOX_CONFIG_NC
12 A simple Unix utility which reads and writes data across network
15 config BUSYBOX_CONFIG_NC_SERVER
16 bool "Netcat server options (-l)"
18 depends on BUSYBOX_CONFIG_NC
20 Allow netcat to act as a server.
22 config BUSYBOX_CONFIG_NC_EXTRA
23 bool "Netcat extensions (-eiw and filename)"
25 depends on BUSYBOX_CONFIG_NC
27 Add -e (support for executing the rest of the command line after
28 making or receiving a successful connection), -i (delay interval for
29 lines sent), -w (timeout for initial connection).
31 config BUSYBOX_CONFIG_NC_110_COMPAT
32 bool "Netcat 1.10 compatibility (+2.5k)"
34 depends on BUSYBOX_CONFIG_NC
36 This option makes nc closely follow original nc-1.10.
37 The code is about 2.5k bigger. It enables
38 -s ADDR, -n, -u, -v, -o FILE, -z options, but loses
39 busybox-specific extensions: -f FILE and -ll.
41 config BUSYBOX_CONFIG_FEATURE_IPV6
42 bool "Enable IPv6 support"
45 Enable IPv6 support in busybox.
46 This adds IPv6 support in the networking applets.
48 config BUSYBOX_CONFIG_FEATURE_UNIX_LOCAL
49 bool "Enable Unix domain socket support (usually not needed)"
52 Enable Unix domain socket support in all busybox networking
53 applets. Address of the form local:/path/to/unix/socket
56 This extension is almost never used in real world usage.
57 You most likely want to say N.
59 config BUSYBOX_CONFIG_FEATURE_PREFER_IPV4_ADDRESS
60 bool "Prefer IPv4 addresses from DNS queries"
62 depends on BUSYBOX_CONFIG_FEATURE_IPV6
64 Use IPv4 address of network host if it has one.
66 If this option is off, the first returned address will be used.
67 This may cause problems when your DNS server is IPv6-capable and
68 is returning IPv6 host addresses too. If IPv6 address
69 precedes IPv4 one in DNS reply, busybox network applets
70 (e.g. wget) will use IPv6 address. On an IPv6-incapable host
71 or network applets will fail to connect to the host
74 config BUSYBOX_CONFIG_VERBOSE_RESOLUTION_ERRORS
75 bool "Verbose resolution errors"
78 Enable if you are not satisfied with simplistic
79 "can't resolve 'hostname.com'" and want to know more.
80 This may increase size of your executable a bit.

106 Add support for extended option like:
107 setageing, setfd, sethello, setmaxage,
108 setpathcost, setportprio, setbridgeprio,
110 This adds about 600 bytes.
112 config BUSYBOX_CONFIG_FEATURE_BRCTL_SHOW
115 depends on BUSYBOX_CONFIG_BRCTL && BUSYBOX_CONFIG_FEATURE_BRCTL_FANCY
117 Add support for option which prints the current config:

151 Enable all kinds of FTP upload commands (-w option)
153 config BUSYBOX_CONFIG_FEATURE_FTPD_ACCEPT_BROKEN_LIST
154 bool "Enable workaround for RFC-violating clients"
156 depends on BUSYBOX_CONFIG_FTPD
158 Some ftp clients (among them KDE's Konqueror) issue illegal
159 "LIST -l" requests. This option works around such problems.
160 It might prevent you from listing files starting with "-" and
161 it increases the code size by ~40 bytes.
162 Most other ftp servers seem to behave similar to this.
164 config BUSYBOX_CONFIG_FTPGET
168 Retrieve a remote file via FTP.
170 config BUSYBOX_CONFIG_FTPPUT
174 Store a remote file via FTP.
176 config BUSYBOX_CONFIG_FEATURE_FTPGETPUT_LONG_OPTIONS
177 bool "Enable long options in ftpget/ftpput"
179 depends on BUSYBOX_CONFIG_LONG_OPTS && (BUSYBOX_CONFIG_FTPGET || BUSYBOX_CONFIG_FTPPUT)
181 Support long options for the ftpget/ftpput applet.
183 config BUSYBOX_CONFIG_HOSTNAME
187 Show or set the system's host name.
189 config BUSYBOX_CONFIG_HTTPD
193 Serve web pages via an HTTP server.
195 config BUSYBOX_CONFIG_FEATURE_HTTPD_RANGES
196 bool "Support 'Ranges:' header"

201 "Range: bytes=NNN-[MMM]" header. Allows for resuming interrupted
202 downloads, seeking in multimedia players etc.
204 config BUSYBOX_CONFIG_FEATURE_HTTPD_USE_SENDFILE
205 bool "Use sendfile system call"
207 depends on BUSYBOX_CONFIG_HTTPD
209 When enabled, httpd will use the kernel sendfile() function
210 instead of read/write loop.
212 config BUSYBOX_CONFIG_FEATURE_HTTPD_SETUID
213 bool "Enable -u <user> option"
215 depends on BUSYBOX_CONFIG_HTTPD
217 This option allows the server to run as a specific user
218 rather than defaulting to the user that starts the server.
219 Use of this option requires special privileges to change to a
222 config BUSYBOX_CONFIG_FEATURE_HTTPD_BASIC_AUTH
223 bool "Enable Basic http Authentication"
225 depends on BUSYBOX_CONFIG_HTTPD

239 bool "Support Common Gateway Interface (CGI)"
241 depends on BUSYBOX_CONFIG_HTTPD
243 This option allows scripts and executables to be invoked
244 when specific URLs are requested.
246 config BUSYBOX_CONFIG_FEATURE_HTTPD_CONFIG_WITH_SCRIPT_INTERPR
247 bool "Support for running scripts through an interpreter"
249 depends on BUSYBOX_CONFIG_FEATURE_HTTPD_CGI
251 This option enables support for running scripts through an
252 interpreter. Turn this on if you want PHP scripts to work
253 properly. You need to supply an additional line in your httpd
255 *.php:/path/to/your/php
257 config BUSYBOX_CONFIG_FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV
258 bool "Set REMOTE_PORT environment variable for CGI"
260 depends on BUSYBOX_CONFIG_FEATURE_HTTPD_CGI
262 Use of this option can assist scripts in generating
263 references that contain a unique port number.
265 config BUSYBOX_CONFIG_FEATURE_HTTPD_ENCODE_URL_STR
266 bool "Enable -e option (useful for CGIs written as shell scripts)"
268 depends on BUSYBOX_CONFIG_HTTPD
270 This option allows html encoding of arbitrary strings for display
271 by the browser. Output goes to stdout.
272 For example, httpd -e "<Hello World>" produces
273 "<Hello World>".
275 config BUSYBOX_CONFIG_FEATURE_HTTPD_ERROR_PAGES
276 bool "Support for custom error pages"
278 depends on BUSYBOX_CONFIG_HTTPD
280 This option allows you to define custom error pages in
281 the configuration file instead of the default HTTP status
282 error pages. For instance, if you add the line:
284 in the config file, the server will respond the specified
285 '/path/e404.html' file instead of the terse '404 NOT FOUND'
288 config BUSYBOX_CONFIG_FEATURE_HTTPD_PROXY
289 bool "Support for reverse proxy"
291 depends on BUSYBOX_CONFIG_HTTPD
293 This option allows you to define URLs that will be forwarded
294 to another HTTP server. To setup add the following line to the
296 P:/url/:http://hostname[:port]/new/path/
297 Then a request to /url/myfile will be forwarded to
298 http://hostname[:port]/new/path/myfile.
300 config BUSYBOX_CONFIG_IFCONFIG
304 Ifconfig is used to configure the kernel-resident network interfaces.
306 config BUSYBOX_CONFIG_FEATURE_IFCONFIG_STATUS
307 bool "Enable status reporting output (+7k)"
309 depends on BUSYBOX_CONFIG_IFCONFIG
311 If ifconfig is called with no arguments it will display the status
312 of the currently active interfaces.
314 config BUSYBOX_CONFIG_FEATURE_IFCONFIG_SLIP
315 bool "Enable slip-specific options \"keepalive\" and \"outfill\""
317 depends on BUSYBOX_CONFIG_IFCONFIG
319 Allow "keepalive" and "outfill" support for SLIP. If you're not
320 planning on using serial lines, leave this unchecked.
322 config BUSYBOX_CONFIG_FEATURE_IFCONFIG_MEMSTART_IOADDR_IRQ
323 bool "Enable options \"mem_start\", \"io_addr\", and \"irq\""
325 depends on BUSYBOX_CONFIG_IFCONFIG
327 Allow the start address for shared memory, start address for I/O,
328 and/or the interrupt line used by the specified device.
330 config BUSYBOX_CONFIG_FEATURE_IFCONFIG_HW
331 bool "Enable option \"hw\" (ether only)"
333 depends on BUSYBOX_CONFIG_IFCONFIG
335 Set the hardware address of this interface, if the device driver
336 supports this operation. Currently, we only support the 'ether'
339 config BUSYBOX_CONFIG_FEATURE_IFCONFIG_BROADCAST_PLUS
340 bool "Set the broadcast automatically"
342 depends on BUSYBOX_CONFIG_IFCONFIG
344 Setting this will make ifconfig attempt to find the broadcast
345 automatically if the value '+' is used.
347 config BUSYBOX_CONFIG_IFENSLAVE
351 Userspace application to bind several interfaces
352 to a logical interface (use with kernel bonding driver).
354 config BUSYBOX_CONFIG_IFPLUGD
358 Network interface plug detection daemon.
360 config BUSYBOX_CONFIG_IFUPDOWN
364 Activate or deactivate the specified interfaces. This applet makes
365 use of either "ifconfig" and "route" or the "ip" command to actually
366 configure network interfaces. Therefore, you will probably also want
367 to enable either IFCONFIG and ROUTE, or enable
368 FEATURE_IFUPDOWN_IP and the various IP options. Of
369 course you could use non-busybox versions of these programs, so
370 against my better judgement (since this will surely result in plenty
371 of support questions on the mailing list), I do not force you to
372 enable these additional options. It is up to you to supply either
373 "ifconfig", "route" and "run-parts" or the "ip" command, either
374 via busybox or via standalone utilities.
376 config BUSYBOX_CONFIG_IFUPDOWN_IFSTATE_PATH
377 string "Absolute path to ifstate file"
379 depends on BUSYBOX_CONFIG_IFUPDOWN
381 ifupdown keeps state information in a file called ifstate.
382 Typically it is located in /var/run/ifstate, however
383 some distributions tend to put it in other places
384 (debian, for example, uses /etc/network/run/ifstate).
385 This config option defines location of ifstate.
387 config BUSYBOX_CONFIG_FEATURE_IFUPDOWN_IP
390 depends on BUSYBOX_CONFIG_IFUPDOWN
392 Use the iproute "ip" command to implement "ifup" and "ifdown", rather
393 than the default of using the older 'ifconfig' and 'route' utilities.

401 select BUSYBOX_CONFIG_FEATURE_IP_LINK
402 select BUSYBOX_CONFIG_FEATURE_IP_ROUTE
404 Use the busybox iproute "ip" applet to implement "ifupdown".
406 If left disabled, you must install the full-blown iproute2
407 utility or the "ifup" and "ifdown" applets will not work.

417 implement the "ifup" and "ifdown" utilities.
419 If left disabled, you must install the full-blown ifconfig
420 and route utilities, or the "ifup" and "ifdown" applets will not
423 config BUSYBOX_CONFIG_FEATURE_IFUPDOWN_IPV4
424 bool "Support for IPv4"
426 depends on BUSYBOX_CONFIG_IFUPDOWN
428 If you want ifup/ifdown to talk IPv4, leave this on.
430 config BUSYBOX_CONFIG_FEATURE_IFUPDOWN_IPV6
431 bool "Support for IPv6"
433 depends on BUSYBOX_CONFIG_IFUPDOWN && BUSYBOX_CONFIG_FEATURE_IPV6

455 bool "Support for external dhcp clients"
457 depends on BUSYBOX_CONFIG_IFUPDOWN
459 This enables support for the external dhcp clients. Clients are
460 tried in the following order: dhcpcd, dhclient, pump and udhcpc.
461 Otherwise, if udhcpc applet is enabled, it is used.
462 Otherwise, ifup/ifdown will have no support for DHCP.

771 bool "Pass TERM type to remote host"
773 depends on BUSYBOX_CONFIG_TELNET
775 Setting this option will forward the TERM environment variable to the

794 A daemon for the TELNET protocol, allowing you to log onto the host
795 running the daemon. Please keep in mind that the TELNET protocol
796 sends passwords in plain text. If you can't afford the space for an
797 SSH daemon and you trust your network, you may say 'y' here. As a
798 more secure alternative, you should seriously consider installing the
799 very small Dropbear SSH daemon instead:
800 http://matt.ucc.asn.au/dropbear/dropbear.html
802 Note that for busybox telnetd to work you need several things:
803 First of all, your kernel needs:
807 Next, you need a /dev/pts directory on your root filesystem:
810 drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/
812 Next you need the pseudo terminal master multiplexer /dev/ptmx:
815 crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
817 Any /dev/ttyp[0-9]* files you may have can be removed.
818 Next, you need to mount the devpts filesystem on /dev/pts using:
820 mount -t devpts devpts /dev/pts
822 You need to be sure that Busybox has LOGIN and
823 FEATURE_SUID enabled. And finally, you should make
824 certain that Busybox has been installed setuid root:
826 chown root.root /bin/busybox
827 chmod 4755 /bin/busybox
829 with all that done, telnetd _should_ work....

845 Example inetd.conf line (note "wait", not usual "nowait"):
847 telnet stream tcp wait root /bin/telnetd telnetd -w10
849 In this example, inetd passes _listening_ socket_ as fd 0
850 to telnetd when connection appears.
851 telnetd will wait for connections until all existing
852 connections are closed, and no new connections
853 appear during 10 seconds. Then it exits, and inetd continues
854 to listen for new connections.
856 This option is rarely used. "tcp nowait" is much more usual
857 way of running tcp services, including telnetd.
858 You most probably want to say N here.
860 config BUSYBOX_CONFIG_TFTP
864 This enables the Trivial File Transfer Protocol client program. TFTP
865 is usually used for simple, small transfers such as a root image
866 for a network-enabled bootloader.
868 config BUSYBOX_CONFIG_TFTPD
872 This enables the Trivial File Transfer Protocol server program.
873 It expects that stdin is a datagram socket and a packet
874 is already pending on it. It will exit after one transfer.
875 In other words: it should be run from inetd in nowait mode,
876 or from udpsvd. Example: "udpsvd -E 0 69 tftpd DIR"
