  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

 388         of either "ifconfig" and "route" or the "ip" command to actually
 389         configure network interfaces. Therefore, you will probably also want
 390         to enable either IFCONFIG and ROUTE, or enable
 391         FEATURE_IFUPDOWN_IP and the various IP options. Of
 392         course you could use non-busybox versions of these programs, so
 393         against my better judgement (since this will surely result in plenty
 394         of support questions on the mailing list), I do not force you to
 395         enable these additional options. It is up to you to supply either
 396         "ifconfig", "route" and "run-parts" or the "ip" command, either
 397         via busybox or via standalone utilities.

 912
 913         Note that for busybox telnetd to work you need several things:
 914         First of all, your kernel needs:
 915                   CONFIG_UNIX98_PTYS=y
 916
 917         Next, you need a /dev/pts directory on your root filesystem:
 918
 919                   $ ls -ld /dev/pts
 920                   drwxr-xr-x  2 root root 0 Sep 23 13:21 /dev/pts/
 921
 922         Next you need the pseudo terminal master multiplexer /dev/ptmx:
 923
 924                   $ ls -la /dev/ptmx
 925                   crw-rw-rw-  1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
 926
 927         Any /dev/ttyp[0-9]* files you may have can be removed.
 928         Next, you need to mount the devpts filesystem on /dev/pts using:
 929
 930                   mount -t devpts devpts /dev/pts
 931
 932         You need to be sure that busybox has LOGIN and
 933         FEATURE_SUID enabled. And finally, you should make
 934         certain that busybox has been installed setuid root:
 935
 936                 chown root.root /bin/busybox
 937                 chmod 4755 /bin/busybox
 938
 939         with all that done, telnetd _should_ work....

 957
 958         In this example, inetd passes _listening_ socket_ as fd 0
 959         to telnetd when connection appears.
 960         telnetd will wait for connections until all existing
 961         connections are closed, and no new connections
 962         appear during 10 seconds. Then it exits, and inetd continues
 963         to listen for new connections.
 964

 966         way of running tcp services, including telnetd.

1129         wget will use internal TLS code to connect to https:// URLs.
1130         It also enables FTPS support, but it's not well tested yet.
1131         Note:
1132         On NOMMU machines, ssl_helper applet should be available
1133         in the $PATH for this to work. Make sure to select that applet.
1134
1135         Note: currently, TLS code only makes TLS I/O work, it
1136         does *not* check that the peer is who it claims to be, etc.
1137         IOW: it uses peer-supplied public keys to establish encryption
1138         and signing keys, then encrypts and signs outgoing data and
1139         decrypts incoming data.
1140         It does not check signature hashes on the incoming data:
1141         this means that attackers manipulating TCP packets can
1142         send altered data and we unknowingly receive garbage.
1143         (This check might be relatively easy to add).
1144         It does not check public key's certificate:
1145         this means that the peer may be an attacker impersonating
1146         the server we think we are talking to.
1147
1148         If you think this is unacceptable, consider this. As more and more
1149         servers switch to HTTPS-only operation, without such "crippled"
1150         TLS code it is *impossible* to simply download a kernel source
1151         from kernel.org. Which can in real world translate into
1152         "my small automatic tooling to build cross-compilers from sources
1153         no longer works, I need to additionally keep a local copy
1154         of ~4 megabyte source tarball of a SSL library and ~2 megabyte
1155         source of wget, need to compile and built both before I can
1156         download anything. All this despite the fact that the build
1157         is done in a QEMU sandbox on a machine with absolutely nothing
1158         worth stealing, so I don't care if someone would go to a lot
1159         of trouble to intercept my HTTPS download to send me an altered
1160         kernel tarball".
1161
1162         If you still think this is unacceptable, send patches.
1163
1164         If you still think this is unacceptable, do not want to send
1165         patches, but do want to waste bandwidth expaining how wrong
1166         it is, you will be ignored.

1177
1178         OpenSSL has a simple SSL client for debug purposes.
1179         If you select this option, wget will effectively run:
1180         "openssl s_client -quiet -connect hostname:443
1181         -servername hostname 2>/dev/null" and pipe its data
1182         through it. -servername is not used if hostname is numeric.
1183         Note inconvenient API: host resolution is done twice,
1184         and there is no guarantee openssl's idea of IPv6 address
1185         format is the same as ours.
1186         Another problem is that s_client prints debug information
1187         to stderr, and it needs to be suppressed. This means
1188         all error messages get suppressed too.
1189         openssl is also a big binary, often dynamically linked
1190         against ~15 libraries.
1191
1192         If openssl can't be executed, internal TLS code will be used
1193         (if you enabled it); if openssl can be executed but fails later,
1194         wget can't detect this, and download will fail.
1195
1196         By default TLS verification is performed, unless
1197         --no-check-certificate option is passed.
