  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

 943
 944         Note that for busybox telnetd to work you need several things:
 945         First of all, your kernel needs:
 946                   CONFIG_UNIX98_PTYS=y
 947
 948         Next, you need a /dev/pts directory on your root filesystem:
 949
 950                   $ ls -ld /dev/pts
 951                   drwxr-xr-x  2 root root 0 Sep 23 13:21 /dev/pts/
 952
 953         Next you need the pseudo terminal master multiplexer /dev/ptmx:
 954
 955                   $ ls -la /dev/ptmx
 956                   crw-rw-rw-  1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
 957
 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:
 960
 961                   mount -t devpts devpts /dev/pts
 962
 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:
 966
 967                 chown root.root /bin/busybox
 968                 chmod 4755 /bin/busybox
 969
 970         with all that done, telnetd _should_ work....

 994
 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.

1166         wget will use internal TLS code to connect to https:// URLs.
1167         It also enables FTPS support, but it's not well tested yet.
1168         Note:
1169         On NOMMU machines, ssl_helper applet should be available
1170         in the $PATH for this to work. Make sure to select that applet.
1171
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.
1184
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
1189         "my small automatic tooling to build cross-compilers from sources
1190         no longer works, I need to additionally keep a local copy
1191         of ~4 megabyte source tarball of a SSL library and ~2 megabyte
1192         source of wget, need to compile and built both before I can
1193         download anything. All this despite the fact that the build
1194         is done in a QEMU sandbox on a machine with absolutely nothing
1195         worth stealing, so I don't care if someone would go to a lot
1196         of trouble to intercept my HTTPS download to send me an altered
1197         kernel tarball".
1198
1199         If you still think this is unacceptable, send patches.
1200
1201         If you still think this is unacceptable, do not want to send
1202         patches, but do want to waste bandwidth expaining how wrong
1203         it is, you will be ignored.

1212         help
1213         Try to use openssl to handle HTTPS.
1214
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.
1228
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.
1232
1233         By default TLS verification is performed, unless
1234         --no-check-certificate option is passed.
