9 config BUSYBOX_FEATURE_IPV6
10 bool "Enable IPv6 support"
13 Enable IPv6 support in busybox.
14 This adds IPv6 support in the networking applets.
16 config BUSYBOX_FEATURE_UNIX_LOCAL
17 bool "Enable Unix domain socket support (usually not needed)"
20 Enable Unix domain socket support in all busybox networking
21 applets. Address of the form local:/path/to/unix/socket
24 This extension is almost never used in real world usage.
25 You most likely want to say N.
27 config BUSYBOX_FEATURE_PREFER_IPV4_ADDRESS
28 bool "Prefer IPv4 addresses from DNS queries"
30 depends on BUSYBOX_FEATURE_IPV6
32 Use IPv4 address of network host if it has one.
34 If this option is off, the first returned address will be used.
35 This may cause problems when your DNS server is IPv6-capable and
36 is returning IPv6 host addresses too. If IPv6 address
37 precedes IPv4 one in DNS reply, busybox network applets
38 (e.g. wget) will use IPv6 address. On an IPv6-incapable host
39 or network applets will fail to connect to the host
42 config BUSYBOX_VERBOSE_RESOLUTION_ERRORS
43 bool "Verbose resolution errors"
46 Enable if you are not satisfied with simplistic
47 "can't resolve 'hostname.com'" and want to know more.
48 This may increase size of your executable a bit.
50 config BUSYBOX_FEATURE_ETC_NETWORKS
51 bool "Support /etc/networks"
54 Enable support for network names in /etc/networks. This is
55 a rarely used feature which allows you to use names
56 instead of IP/mask pairs in route command.
58 config BUSYBOX_FEATURE_ETC_SERVICES
59 bool "Consult /etc/services even for well-known ports"
62 Look up e.g. "telnet" and "http" in /etc/services file
63 instead of assuming ports 23 and 80.
64 This is almost never necessary (everybody uses standard ports),
65 and it makes sense to avoid reading this file.
66 If you disable this option, in the cases where port is explicitly
67 specified as a service name (e.g. "telnet HOST PORTNAME"),
68 it will still be looked up in /etc/services.
70 config BUSYBOX_FEATURE_HWIB
71 bool "Support infiniband HW"
74 Support for printing infiniband addresses in network applets.
76 config BUSYBOX_FEATURE_TLS_SHA1
77 bool "In TLS code, support ciphers which use deprecated SHA1"
78 depends on BUSYBOX_TLS
81 Selecting this option increases interoperability with very old
82 servers, but slightly increases code size.
84 Most TLS servers support SHA256 today (2018), since SHA1 is
85 considered possibly insecure (although not yet definitely broken).
91 Manipulate the system ARP cache.
96 Ping hosts by ARP packets.
101 Manage ethernet bridges.
102 Supports addbr/delbr and addif/delif.
104 config BUSYBOX_FEATURE_BRCTL_FANCY
107 depends on BUSYBOX_BRCTL
109 Add support for extended option like:
110 setageing, setfd, sethello, setmaxage,
111 setpathcost, setportprio, setbridgeprio,
113 This adds about 600 bytes.
115 config BUSYBOX_FEATURE_BRCTL_SHOW
118 depends on BUSYBOX_BRCTL && BUSYBOX_FEATURE_BRCTL_FANCY
120 Add support for option which prints the current config:
126 Small and static DNS server daemon.
127 config BUSYBOX_ETHER_WAKE
128 bool "ether-wake (4.9 kb)"
131 Send a magic packet to wake up sleeping machines.
136 Simple FTP daemon. You have to run it via inetd.
138 config BUSYBOX_FEATURE_FTPD_WRITE
139 bool "Enable -w (upload commands)"
141 depends on BUSYBOX_FTPD
143 Enable -w option. "ftpd -w" will accept upload commands
144 such as STOR, STOU, APPE, DELE, MKD, RMD, rename commands.
146 config BUSYBOX_FEATURE_FTPD_ACCEPT_BROKEN_LIST
147 bool "Enable workaround for RFC-violating clients"
149 depends on BUSYBOX_FTPD
151 Some ftp clients (among them KDE's Konqueror) issue illegal
152 "LIST -l" requests. This option works around such problems.
153 It might prevent you from listing files starting with "-" and
154 it increases the code size by ~40 bytes.
155 Most other ftp servers seem to behave similar to this.
157 config BUSYBOX_FEATURE_FTPD_AUTHENTICATION
158 bool "Enable authentication"
160 depends on BUSYBOX_FTPD
162 Require login, and change to logged in user's UID:GID before
163 accessing any files. Option "-a USER" allows "anonymous"
164 logins (treats them as if USER logged in).
166 If this option is not selected, ftpd runs with the rights
167 of the user it was started under, and does not require login.
168 Take care to not launch it under root.
169 config BUSYBOX_FTPGET
170 bool "ftpget (7.8 kb)"
173 Retrieve a remote file via FTP.
175 config BUSYBOX_FTPPUT
176 bool "ftpput (7.5 kb)"
179 Store a remote file via FTP.
181 config BUSYBOX_FEATURE_FTPGETPUT_LONG_OPTIONS
182 bool "Enable long options in ftpget/ftpput"
184 depends on BUSYBOX_LONG_OPTS && (BUSYBOX_FTPGET || BUSYBOX_FTPPUT)
185 config BUSYBOX_HOSTNAME
186 bool "hostname (5.5 kb)"
189 Show or set the system's host name.
191 config BUSYBOX_DNSDOMAINNAME
192 bool "dnsdomainname (3.6 kb)"
195 Alias to "hostname -d".
202 config BUSYBOX_FEATURE_HTTPD_PORT_DEFAULT
206 depends on BUSYBOX_HTTPD
208 config BUSYBOX_FEATURE_HTTPD_RANGES
209 bool "Support 'Ranges:' header"
211 depends on BUSYBOX_HTTPD
213 Makes httpd emit "Accept-Ranges: bytes" header and understand
214 "Range: bytes=NNN-[MMM]" header. Allows for resuming interrupted
215 downloads, seeking in multimedia players etc.
217 config BUSYBOX_FEATURE_HTTPD_SETUID
218 bool "Enable -u <user> option"
220 depends on BUSYBOX_HTTPD
222 This option allows the server to run as a specific user
223 rather than defaulting to the user that starts the server.
224 Use of this option requires special privileges to change to a
227 config BUSYBOX_FEATURE_HTTPD_BASIC_AUTH
228 bool "Enable HTTP authentication"
230 depends on BUSYBOX_HTTPD
232 Utilizes password settings from /etc/httpd.conf for basic
233 authentication on a per url basis.
234 Example for httpd.conf file:
237 config BUSYBOX_FEATURE_HTTPD_AUTH_MD5
238 bool "Support MD5-encrypted passwords in HTTP authentication"
240 depends on BUSYBOX_FEATURE_HTTPD_BASIC_AUTH
242 Enables encrypted passwords, and wildcard user/passwords
244 User '*' means 'any system user name is ok',
245 password of '*' means 'use system password for this user'
247 /adm:toor:$1$P/eKnWXS$aI1aPGxT.dJD5SzqAKWrF0
251 config BUSYBOX_FEATURE_HTTPD_CGI
252 bool "Support Common Gateway Interface (CGI)"
254 depends on BUSYBOX_HTTPD
256 This option allows scripts and executables to be invoked
257 when specific URLs are requested.
259 config BUSYBOX_FEATURE_HTTPD_CONFIG_WITH_SCRIPT_INTERPR
260 bool "Support running scripts through an interpreter"
262 depends on BUSYBOX_FEATURE_HTTPD_CGI
264 This option enables support for running scripts through an
265 interpreter. Turn this on if you want PHP scripts to work
266 properly. You need to supply an additional line in your
268 *.php:/path/to/your/php
270 config BUSYBOX_FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV
271 bool "Set REMOTE_PORT environment variable for CGI"
273 depends on BUSYBOX_FEATURE_HTTPD_CGI
275 Use of this option can assist scripts in generating
276 references that contain a unique port number.
278 config BUSYBOX_FEATURE_HTTPD_ENCODE_URL_STR
279 bool "Enable -e option (useful for CGIs written as shell scripts)"
281 depends on BUSYBOX_HTTPD
283 This option allows html encoding of arbitrary strings for display
284 by the browser. Output goes to stdout.
285 For example, httpd -e "<Hello World>" produces
286 "<Hello World>".
288 config BUSYBOX_FEATURE_HTTPD_ERROR_PAGES
289 bool "Support custom error pages"
291 depends on BUSYBOX_HTTPD
293 This option allows you to define custom error pages in
294 the configuration file instead of the default HTTP status
295 error pages. For instance, if you add the line:
297 in the config file, the server will respond the specified
298 '/path/e404.html' file instead of the terse '404 NOT FOUND'
301 config BUSYBOX_FEATURE_HTTPD_PROXY
302 bool "Support reverse proxy"
304 depends on BUSYBOX_HTTPD
306 This option allows you to define URLs that will be forwarded
307 to another HTTP server. To setup add the following line to the
309 P:/url/:http://hostname[:port]/new/path/
310 Then a request to /url/myfile will be forwarded to
311 http://hostname[:port]/new/path/myfile.
313 config BUSYBOX_FEATURE_HTTPD_GZIP
314 bool "Support GZIP content encoding"
316 depends on BUSYBOX_HTTPD
318 Makes httpd send files using GZIP content encoding if the
319 client supports it and a pre-compressed <file>.gz exists.
321 config BUSYBOX_FEATURE_HTTPD_ETAG
322 bool "Support caching via ETag header"
324 depends on BUSYBOX_HTTPD
326 If server responds with ETag then next time client (browser)
327 resend it via If-None-Match header.
328 Then httpd will check if file wasn't modified and if not,
329 return 304 Not Modified status code.
330 The ETag value is constructed from last modification date
331 in unix epoch, and size: "hex(last_mod)-hex(file_size)".
332 It's not completely reliable as hash functions but fair enough.
334 config BUSYBOX_FEATURE_HTTPD_LAST_MODIFIED
335 bool "Add Last-Modified header to response"
337 depends on BUSYBOX_HTTPD
339 The Last-Modified header is used for cache validation.
340 The client sends last seen mtime to server in If-Modified-Since.
341 Both headers MUST be an RFC 1123 formatted, which is hard to parse.
342 Use ETag header instead.
344 config BUSYBOX_FEATURE_HTTPD_DATE
345 bool "Add Date header to response"
347 depends on BUSYBOX_HTTPD
349 RFC2616 says that server MUST add Date header to response.
350 But it is almost useless and can be omitted.
352 config BUSYBOX_FEATURE_HTTPD_ACL_IP
355 depends on BUSYBOX_HTTPD
357 Support IP deny/allow rules
358 config BUSYBOX_IFCONFIG
359 bool "ifconfig (12 kb)"
362 Ifconfig is used to configure the kernel-resident network interfaces.
364 config BUSYBOX_FEATURE_IFCONFIG_STATUS
365 bool "Enable status reporting output (+7k)"
367 depends on BUSYBOX_IFCONFIG
369 If ifconfig is called with no arguments it will display the status
370 of the currently active interfaces.
372 config BUSYBOX_FEATURE_IFCONFIG_SLIP
373 bool "Enable slip-specific options \"keepalive\" and \"outfill\""
375 depends on BUSYBOX_IFCONFIG
377 Allow "keepalive" and "outfill" support for SLIP. If you're not
378 planning on using serial lines, leave this unchecked.
380 config BUSYBOX_FEATURE_IFCONFIG_MEMSTART_IOADDR_IRQ
381 bool "Enable options \"mem_start\", \"io_addr\", and \"irq\""
383 depends on BUSYBOX_IFCONFIG
385 Allow the start address for shared memory, start address for I/O,
386 and/or the interrupt line used by the specified device.
388 config BUSYBOX_FEATURE_IFCONFIG_HW
389 bool "Enable option \"hw\" (ether only)"
391 depends on BUSYBOX_IFCONFIG
393 Set the hardware address of this interface, if the device driver
394 supports this operation. Currently, we only support the 'ether'
397 config BUSYBOX_FEATURE_IFCONFIG_BROADCAST_PLUS
398 bool "Set the broadcast automatically"
400 depends on BUSYBOX_IFCONFIG
402 Setting this will make ifconfig attempt to find the broadcast
403 automatically if the value '+' is used.
404 config BUSYBOX_IFENSLAVE
405 bool "ifenslave (13 kb)"
408 Userspace application to bind several interfaces
409 to a logical interface (use with kernel bonding driver).
410 config BUSYBOX_IFPLUGD
411 bool "ifplugd (10 kb)"
414 Network interface plug detection daemon.
419 Activate the specified interfaces. This applet makes use
420 of either "ifconfig" and "route" or the "ip" command to actually
421 configure network interfaces. Therefore, you will probably also want
422 to enable either IFCONFIG and ROUTE, or enable
423 FEATURE_IFUPDOWN_IP and the various IP options. Of
424 course you could use non-busybox versions of these programs, so
425 against my better judgement (since this will surely result in plenty
426 of support questions on the mailing list), I do not force you to
427 enable these additional options. It is up to you to supply either
428 "ifconfig", "route" and "run-parts" or the "ip" command, either
429 via busybox or via standalone utilities.
431 config BUSYBOX_IFDOWN
432 bool "ifdown (13 kb)"
435 Deactivate the specified interfaces.
437 config BUSYBOX_IFUPDOWN_IFSTATE_PATH
438 string "Absolute path to ifstate file"
439 default "/var/run/ifstate"
440 depends on BUSYBOX_IFUP || BUSYBOX_IFDOWN
442 ifupdown keeps state information in a file called ifstate.
443 Typically it is located in /var/run/ifstate, however
444 some distributions tend to put it in other places
445 (debian, for example, uses /etc/network/run/ifstate).
446 This config option defines location of ifstate.
448 config BUSYBOX_FEATURE_IFUPDOWN_IP
449 bool "Use ip tool (else ifconfig/route is used)"
451 depends on BUSYBOX_IFUP || BUSYBOX_IFDOWN
453 Use the iproute "ip" command to implement "ifup" and "ifdown", rather
454 than the default of using the older "ifconfig" and "route" utilities.
456 If Y: you must install either the full-blown iproute2 package
457 or enable "ip" applet in busybox, or the "ifup" and "ifdown" applets
460 If N: you must install either the full-blown ifconfig and route
461 utilities, or enable these applets in busybox.
463 config BUSYBOX_FEATURE_IFUPDOWN_IPV4
466 depends on BUSYBOX_IFUP || BUSYBOX_IFDOWN
468 If you want ifup/ifdown to talk IPv4, leave this on.
470 config BUSYBOX_FEATURE_IFUPDOWN_IPV6
473 depends on (BUSYBOX_IFUP || BUSYBOX_IFDOWN) && BUSYBOX_FEATURE_IPV6
475 If you need support for IPv6, turn this option on.
478 config BUSYBOX_FEATURE_IFUPDOWN_MAPPING
479 bool "Enable mapping support"
481 depends on BUSYBOX_IFUP || BUSYBOX_IFDOWN
483 This enables support for the "mapping" stanza, unless you have
484 a weird network setup you don't need it.
486 config BUSYBOX_FEATURE_IFUPDOWN_EXTERNAL_DHCP
487 bool "Support external DHCP clients"
489 depends on BUSYBOX_IFUP || BUSYBOX_IFDOWN
491 This enables support for the external dhcp clients. Clients are
492 tried in the following order: dhcpcd, dhclient, pump and udhcpc.
493 Otherwise, if udhcpc applet is enabled, it is used.
494 Otherwise, ifup/ifdown will have no support for DHCP.
498 select BUSYBOX_FEATURE_SYSLOG

931 A daemon for the TELNET protocol, allowing you to log onto the host
932 running the daemon. Please keep in mind that the TELNET protocol
933 sends passwords in plain text. If you can't afford the space for an
934 SSH daemon and you trust your network, you may say 'y' here. As a
935 more secure alternative, you should seriously consider installing the
936 very small Dropbear SSH daemon instead:
937 http://matt.ucc.asn.au/dropbear/dropbear.html
939 Note that for busybox telnetd to work you need several things:
940 First of all, your kernel needs:
943 Next, you need a /dev/pts directory on your root filesystem:
946 drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/
948 Next you need the pseudo terminal master multiplexer /dev/ptmx:
951 crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
953 Any /dev/ttyp[0-9]* files you may have can be removed.
954 Next, you need to mount the devpts filesystem on /dev/pts using:
956 mount -t devpts devpts /dev/pts
958 You need to be sure that busybox has LOGIN and
959 FEATURE_SUID enabled. And finally, you should make
960 certain that busybox has been installed setuid root:
962 chown root.root /bin/busybox
963 chmod 4755 /bin/busybox
965 with all that done, telnetd _should_ work....

981 bool "Support -w SEC option (inetd wait mode)"
983 depends on BUSYBOX_FEATURE_TELNETD_STANDALONE
985 This option allows you to run telnetd in "inet wait" mode.
986 Example inetd.conf line (note "wait", not usual "nowait"):
988 telnet stream tcp wait root /bin/telnetd telnetd -w10
990 In this example, inetd passes _listening_ socket_ as fd 0
991 to telnetd when connection appears.
992 telnetd will wait for connections until all existing
993 connections are closed, and no new connections
994 appear during 10 seconds. Then it exits, and inetd continues
995 to listen for new connections.
997 This option is rarely used. "tcp nowait" is much more usual
998 way of running tcp services, including telnetd.
999 You most probably want to say N here.

1023 It expects that stdin is a datagram socket and a packet
1024 is already pending on it. It will exit after one transfer.
1025 In other words: it should be run from inetd in nowait mode,

1148 command line option.
1150 Currently only connect and network data read timeout are
1151 supported (i.e., timeout is not applied to the DNS query). When
1152 FEATURE_WGET_LONG_OPTIONS is also enabled, the --timeout option
1153 will work in addition to -T.
1155 config BUSYBOX_FEATURE_WGET_HTTPS
1156 bool "Support HTTPS using internal TLS code"
1158 depends on BUSYBOX_WGET
1161 wget will use internal TLS code to connect to https:// URLs.
1162 It also enables FTPS support, but it's not well tested yet.
1164 On NOMMU machines, ssl_helper applet should be available
1165 in the $PATH for this to work. Make sure to select that applet.
1167 Note: currently, TLS code only makes TLS I/O work, it
1168 does *not* check that the peer is who it claims to be, etc.
1169 IOW: it uses peer-supplied public keys to establish encryption
1170 and signing keys, then encrypts and signs outgoing data and
1171 decrypts incoming data.
1172 It does not check signature hashes on the incoming data:
1173 this means that attackers manipulating TCP packets can
1174 send altered data and we unknowingly receive garbage.
1175 (This check might be relatively easy to add).
1176 It does not check public key's certificate:
1177 this means that the peer may be an attacker impersonating
1178 the server we think we are talking to.
1180 If you think this is unacceptable, consider this. As more and more
1181 servers switch to HTTPS-only operation, without such "crippled"
1182 TLS code it is *impossible* to simply download a kernel source
1183 from kernel.org. Which can in real world translate into
1184 "my small automatic tooling to build cross-compilers from sources
1185 no longer works, I need to additionally keep a local copy
1186 of ~4 megabyte source tarball of a SSL library and ~2 megabyte
1187 source of wget, need to compile and built both before I can
1188 download anything. All this despite the fact that the build
1189 is done in a QEMU sandbox on a machine with absolutely nothing
1190 worth stealing, so I don't care if someone would go to a lot
1191 of trouble to intercept my HTTPS download to send me an altered
1194 If you still think this is unacceptable, send patches.
1196 If you still think this is unacceptable, do not want to send
1197 patches, but do want to waste bandwidth expaining how wrong
1198 it is, you will be ignored.
1200 FEATURE_WGET_OPENSSL does implement TLS verification
1201 using the certificates available to OpenSSL.
1203 config BUSYBOX_FEATURE_WGET_OPENSSL
1204 bool "Try to connect to HTTPS using openssl"
1206 depends on BUSYBOX_WGET
1208 Try to use openssl to handle HTTPS.
1210 OpenSSL has a simple SSL client for debug purposes.
1211 If you select this option, wget will effectively run:
1212 "openssl s_client -quiet -connect hostname:443
1213 -servername hostname 2>/dev/null" and pipe its data
1214 through it. -servername is not used if hostname is numeric.
1215 Note inconvenient API: host resolution is done twice,
1216 and there is no guarantee openssl's idea of IPv6 address
1217 format is the same as ours.
1218 Another problem is that s_client prints debug information
1219 to stderr, and it needs to be suppressed. This means
1220 all error messages get suppressed too.
1221 openssl is also a big binary, often dynamically linked
1222 against ~15 libraries.
1224 If openssl can't be executed, internal TLS code will be used
1225 (if you enabled it); if openssl can be executed but fails later,
1226 wget can't detect this, and download will fail.
1228 By default BUSYBOX_TLS verification is performed, unless
1229 --no-check-certificate option is passed.
