9 config BUSYBOX_CONFIG_FEATURE_IPV6
10 bool "Enable IPv6 support"
11 default BUSYBOX_DEFAULT_FEATURE_IPV6
13 Enable IPv6 support in busybox.
14 This adds IPv6 support in the networking applets.
16 config BUSYBOX_CONFIG_FEATURE_UNIX_LOCAL
17 bool "Enable Unix domain socket support (usually not needed)"
18 default BUSYBOX_DEFAULT_FEATURE_UNIX_LOCAL
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_CONFIG_FEATURE_PREFER_IPV4_ADDRESS
28 bool "Prefer IPv4 addresses from DNS queries"
29 default BUSYBOX_DEFAULT_FEATURE_PREFER_IPV4_ADDRESS
30 depends on BUSYBOX_CONFIG_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_CONFIG_VERBOSE_RESOLUTION_ERRORS
43 bool "Verbose resolution errors"
44 default BUSYBOX_DEFAULT_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_CONFIG_FEATURE_ETC_NETWORKS
51 bool "Support /etc/networks"
52 default BUSYBOX_DEFAULT_FEATURE_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_CONFIG_FEATURE_ETC_SERVICES
59 bool "Consult /etc/services even for well-known ports"
60 default BUSYBOX_DEFAULT_FEATURE_ETC_SERVICES
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_CONFIG_FEATURE_HWIB
71 bool "Support infiniband HW"
72 default BUSYBOX_DEFAULT_FEATURE_HWIB
74 Support for printing infiniband addresses in network applets.
76 config BUSYBOX_CONFIG_FEATURE_TLS_SHA1
77 bool "In TLS code, support ciphers which use deprecated SHA1"
78 depends on BUSYBOX_CONFIG_TLS
79 default BUSYBOX_DEFAULT_FEATURE_TLS_SHA1
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).
87 config BUSYBOX_CONFIG_ARP
89 default BUSYBOX_DEFAULT_ARP
91 Manipulate the system ARP cache.
92 config BUSYBOX_CONFIG_ARPING
94 default BUSYBOX_DEFAULT_ARPING
96 Ping hosts by ARP packets.
97 config BUSYBOX_CONFIG_BRCTL
99 default BUSYBOX_DEFAULT_BRCTL
101 Manage ethernet bridges.
102 Supports addbr/delbr and addif/delif.
104 config BUSYBOX_CONFIG_FEATURE_BRCTL_FANCY
106 default BUSYBOX_DEFAULT_FEATURE_BRCTL_FANCY
107 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_BRCTL_SHOW
117 default BUSYBOX_DEFAULT_FEATURE_BRCTL_SHOW
118 depends on BUSYBOX_CONFIG_BRCTL && BUSYBOX_CONFIG_FEATURE_BRCTL_FANCY
120 Add support for option which prints the current config:
122 config BUSYBOX_CONFIG_DNSD
124 default BUSYBOX_DEFAULT_DNSD
126 Small and static DNS server daemon.
127 config BUSYBOX_CONFIG_ETHER_WAKE
128 bool "ether-wake (4.9 kb)"
129 default BUSYBOX_DEFAULT_ETHER_WAKE
131 Send a magic packet to wake up sleeping machines.
132 config BUSYBOX_CONFIG_FTPD
134 default BUSYBOX_DEFAULT_FTPD
136 Simple FTP daemon. You have to run it via inetd.
138 config BUSYBOX_CONFIG_FEATURE_FTPD_WRITE
139 bool "Enable -w (upload commands)"
140 default BUSYBOX_DEFAULT_FEATURE_FTPD_WRITE
141 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_FTPD_ACCEPT_BROKEN_LIST
147 bool "Enable workaround for RFC-violating clients"
148 default BUSYBOX_DEFAULT_FEATURE_FTPD_ACCEPT_BROKEN_LIST
149 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_FTPD_AUTHENTICATION
158 bool "Enable authentication"
159 default BUSYBOX_DEFAULT_FEATURE_FTPD_AUTHENTICATION
160 depends on BUSYBOX_CONFIG_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_CONFIG_FTPGET
170 bool "ftpget (7.8 kb)"
171 default BUSYBOX_DEFAULT_FTPGET
173 Retrieve a remote file via FTP.
175 config BUSYBOX_CONFIG_FTPPUT
176 bool "ftpput (7.5 kb)"
177 default BUSYBOX_DEFAULT_FTPPUT
179 Store a remote file via FTP.
181 config BUSYBOX_CONFIG_FEATURE_FTPGETPUT_LONG_OPTIONS
182 bool "Enable long options in ftpget/ftpput"
183 default BUSYBOX_DEFAULT_FEATURE_FTPGETPUT_LONG_OPTIONS
184 depends on BUSYBOX_CONFIG_LONG_OPTS && (BUSYBOX_CONFIG_FTPGET || BUSYBOX_CONFIG_FTPPUT)
185 config BUSYBOX_CONFIG_HOSTNAME
186 bool "hostname (5.5 kb)"
187 default BUSYBOX_DEFAULT_HOSTNAME
189 Show or set the system's host name.
191 config BUSYBOX_CONFIG_DNSDOMAINNAME
192 bool "dnsdomainname (3.6 kb)"
193 default BUSYBOX_DEFAULT_DNSDOMAINNAME
195 Alias to "hostname -d".
196 config BUSYBOX_CONFIG_HTTPD
198 default BUSYBOX_DEFAULT_HTTPD
202 config BUSYBOX_CONFIG_FEATURE_HTTPD_PORT_DEFAULT
204 default BUSYBOX_DEFAULT_FEATURE_HTTPD_PORT_DEFAULT
206 depends on BUSYBOX_CONFIG_HTTPD
208 config BUSYBOX_CONFIG_FEATURE_HTTPD_RANGES
209 bool "Support 'Ranges:' header"
210 default BUSYBOX_DEFAULT_FEATURE_HTTPD_RANGES
211 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_HTTPD_SETUID
218 bool "Enable -u <user> option"
219 default BUSYBOX_DEFAULT_FEATURE_HTTPD_SETUID
220 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_HTTPD_BASIC_AUTH
228 bool "Enable HTTP authentication"
229 default BUSYBOX_DEFAULT_FEATURE_HTTPD_BASIC_AUTH
230 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_HTTPD_AUTH_MD5
238 bool "Support MD5-encrypted passwords in HTTP authentication"
239 default BUSYBOX_DEFAULT_FEATURE_HTTPD_AUTH_MD5
240 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_HTTPD_CGI
252 bool "Support Common Gateway Interface (CGI)"
253 default BUSYBOX_DEFAULT_FEATURE_HTTPD_CGI
254 depends on BUSYBOX_CONFIG_HTTPD
256 This option allows scripts and executables to be invoked
257 when specific URLs are requested.
259 config BUSYBOX_CONFIG_FEATURE_HTTPD_CONFIG_WITH_SCRIPT_INTERPR
260 bool "Support running scripts through an interpreter"
261 default BUSYBOX_DEFAULT_FEATURE_HTTPD_CONFIG_WITH_SCRIPT_INTERPR
262 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV
271 bool "Set REMOTE_PORT environment variable for CGI"
272 default BUSYBOX_DEFAULT_FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV
273 depends on BUSYBOX_CONFIG_FEATURE_HTTPD_CGI
275 Use of this option can assist scripts in generating
276 references that contain a unique port number.
278 config BUSYBOX_CONFIG_FEATURE_HTTPD_ENCODE_URL_STR
279 bool "Enable -e option (useful for CGIs written as shell scripts)"
280 default BUSYBOX_DEFAULT_FEATURE_HTTPD_ENCODE_URL_STR
281 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_HTTPD_ERROR_PAGES
289 bool "Support custom error pages"
290 default BUSYBOX_DEFAULT_FEATURE_HTTPD_ERROR_PAGES
291 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_HTTPD_PROXY
302 bool "Support reverse proxy"
303 default BUSYBOX_DEFAULT_FEATURE_HTTPD_PROXY
304 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_HTTPD_GZIP
314 bool "Support GZIP content encoding"
315 default BUSYBOX_DEFAULT_FEATURE_HTTPD_GZIP
316 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_HTTPD_ETAG
322 bool "Support caching via ETag header"
323 default BUSYBOX_DEFAULT_FEATURE_HTTPD_ETAG
324 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_HTTPD_LAST_MODIFIED
335 bool "Add Last-Modified header to response"
336 default BUSYBOX_DEFAULT_FEATURE_HTTPD_LAST_MODIFIED
337 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_HTTPD_DATE
345 bool "Add Date header to response"
346 default BUSYBOX_DEFAULT_FEATURE_HTTPD_DATE
347 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_HTTPD_ACL_IP
354 default BUSYBOX_DEFAULT_FEATURE_HTTPD_ACL_IP
355 depends on BUSYBOX_CONFIG_HTTPD
357 Support IP deny/allow rules
358 config BUSYBOX_CONFIG_IFCONFIG
359 bool "ifconfig (12 kb)"
360 default BUSYBOX_DEFAULT_IFCONFIG
362 Ifconfig is used to configure the kernel-resident network interfaces.
364 config BUSYBOX_CONFIG_FEATURE_IFCONFIG_STATUS
365 bool "Enable status reporting output (+7k)"
366 default BUSYBOX_DEFAULT_FEATURE_IFCONFIG_STATUS
367 depends on BUSYBOX_CONFIG_IFCONFIG
369 If ifconfig is called with no arguments it will display the status
370 of the currently active interfaces.
372 config BUSYBOX_CONFIG_FEATURE_IFCONFIG_SLIP
373 bool "Enable slip-specific options \"keepalive\" and \"outfill\""
374 default BUSYBOX_DEFAULT_FEATURE_IFCONFIG_SLIP
375 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_IFCONFIG_MEMSTART_IOADDR_IRQ
381 bool "Enable options \"mem_start\", \"io_addr\", and \"irq\""
382 default BUSYBOX_DEFAULT_FEATURE_IFCONFIG_MEMSTART_IOADDR_IRQ
383 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_IFCONFIG_HW
389 bool "Enable option \"hw\" (ether only)"
390 default BUSYBOX_DEFAULT_FEATURE_IFCONFIG_HW
391 depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_IFCONFIG_BROADCAST_PLUS
398 bool "Set the broadcast automatically"
399 default BUSYBOX_DEFAULT_FEATURE_IFCONFIG_BROADCAST_PLUS
400 depends on BUSYBOX_CONFIG_IFCONFIG
402 Setting this will make ifconfig attempt to find the broadcast
403 automatically if the value '+' is used.
404 config BUSYBOX_CONFIG_IFENSLAVE
405 bool "ifenslave (13 kb)"
406 default BUSYBOX_DEFAULT_IFENSLAVE
408 Userspace application to bind several interfaces
409 to a logical interface (use with kernel bonding driver).
410 config BUSYBOX_CONFIG_IFPLUGD
411 bool "ifplugd (10 kb)"
412 default BUSYBOX_DEFAULT_IFPLUGD
414 Network interface plug detection daemon.
415 config BUSYBOX_CONFIG_IFUP
417 default BUSYBOX_DEFAULT_IFUP
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_CONFIG_IFDOWN
432 bool "ifdown (13 kb)"
433 default BUSYBOX_DEFAULT_IFDOWN
435 Deactivate the specified interfaces.
437 config BUSYBOX_CONFIG_IFUPDOWN_IFSTATE_PATH
438 string "Absolute path to ifstate file"
439 default BUSYBOX_DEFAULT_IFUPDOWN_IFSTATE_PATH
440 depends on BUSYBOX_CONFIG_IFUP || BUSYBOX_CONFIG_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_CONFIG_FEATURE_IFUPDOWN_IP
449 bool "Use ip tool (else ifconfig/route is used)"
450 default BUSYBOX_DEFAULT_FEATURE_IFUPDOWN_IP
451 depends on BUSYBOX_CONFIG_IFUP || BUSYBOX_CONFIG_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_CONFIG_FEATURE_IFUPDOWN_IPV4
465 default BUSYBOX_DEFAULT_FEATURE_IFUPDOWN_IPV4
466 depends on BUSYBOX_CONFIG_IFUP || BUSYBOX_CONFIG_IFDOWN
468 If you want ifup/ifdown to talk IPv4, leave this on.
470 config BUSYBOX_CONFIG_FEATURE_IFUPDOWN_IPV6
472 default BUSYBOX_DEFAULT_FEATURE_IFUPDOWN_IPV6
473 depends on (BUSYBOX_CONFIG_IFUP || BUSYBOX_CONFIG_IFDOWN) && BUSYBOX_CONFIG_FEATURE_IPV6
475 If you need support for IPv6, turn this option on.
478 config BUSYBOX_CONFIG_FEATURE_IFUPDOWN_MAPPING
479 bool "Enable mapping support"
480 default BUSYBOX_DEFAULT_FEATURE_IFUPDOWN_MAPPING
481 depends on BUSYBOX_CONFIG_IFUP || BUSYBOX_CONFIG_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_CONFIG_FEATURE_IFUPDOWN_EXTERNAL_DHCP
487 bool "Support external DHCP clients"
488 default BUSYBOX_DEFAULT_FEATURE_IFUPDOWN_EXTERNAL_DHCP
489 depends on BUSYBOX_CONFIG_IFUP || BUSYBOX_CONFIG_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.
495 config BUSYBOX_CONFIG_INETD
497 default BUSYBOX_DEFAULT_INETD
498 select BUSYBOX_CONFIG_FEATURE_SYSLOG

560 Support Sun-RPC based services
561 config BUSYBOX_CONFIG_IP
563 default BUSYBOX_DEFAULT_IP
565 The "ip" applet is a TCP/IP interface configuration and routing
567 Short forms (enabled below) are busybox-specific extensions.
568 The standard "ip" utility does not provide them. If you are
569 trying to be portable, it's better to use "ip CMD" forms.

944 Note that for busybox telnetd to work you need several things:
945 First of all, your kernel needs:
948 Next, you need a /dev/pts directory on your root filesystem:
951 drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/
953 Next you need the pseudo terminal master multiplexer /dev/ptmx:
956 crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
958 Any /dev/ttyp[0-9]* files you may have can be removed.
959 Next, you need to mount the devpts filesystem on /dev/pts using:
961 mount -t devpts devpts /dev/pts
963 You need to be sure that busybox has LOGIN and
964 FEATURE_SUID enabled. And finally, you should make
965 certain that busybox has been installed setuid root:

995 In this example, inetd passes _listening_ socket_ as fd 0
996 to telnetd when connection appears.
997 telnetd will wait for connections until all existing
998 connections are closed, and no new connections
999 appear during 10 seconds. Then it exits, and inetd continues
1000 to listen for new connections.

1169 On NOMMU machines, ssl_helper applet should be available

1172 Note: currently, TLS code only makes TLS I/O work, it
1173 does *not* check that the peer is who it claims to be, etc.
1174 IOW: it uses peer-supplied public keys to establish encryption
1175 and signing keys, then encrypts and signs outgoing data and
1176 decrypts incoming data.
1177 It does not check signature hashes on the incoming data:
1178 this means that attackers manipulating TCP packets can
1179 send altered data and we unknowingly receive garbage.
1180 (This check might be relatively easy to add).
1181 It does not check public key's certificate:
1182 this means that the peer may be an attacker impersonating
1183 the server we think we are talking to.
1185 If you think this is unacceptable, consider this. As more and more
1186 servers switch to HTTPS-only operation, without such "crippled"
1187 TLS code it is *impossible* to simply download a kernel source
1188 from kernel.org. Which can in real world translate into

1211 depends on BUSYBOX_CONFIG_WGET
1213 Try to use openssl to handle HTTPS.
1215 OpenSSL has a simple SSL client for debug purposes.
1216 If you select this option, wget will effectively run:
1217 "openssl s_client -quiet -connect hostname:443
1218 -servername hostname 2>/dev/null" and pipe its data
1219 through it. -servername is not used if hostname is numeric.
1220 Note inconvenient API: host resolution is done twice,
1221 and there is no guarantee openssl's idea of IPv6 address
1222 format is the same as ours.
1223 Another problem is that s_client prints debug information
1224 to stderr, and it needs to be suppressed. This means
1225 all error messages get suppressed too.
1226 openssl is also a big binary, often dynamically linked
1227 against ~15 libraries.
1229 If openssl can't be executed, internal TLS code will be used
1230 (if you enabled it); if openssl can be executed but fails later,
1231 wget can't detect this, and download will fail.
