config FEATURE_IPV6
bool "Enable IPv6 support"
default n
help
Enable IPv6 support in busybox.
This adds IPv6 support in the networking applets.
config FEATURE_PREFER_IPV4_ADDRESS
bool "Preferentially use IPv4 addresses from DNS queries"
default y
depends on FEATURE_IPV6
help
Use IPv4 address of network host if it has one.
If this option is off, the first returned address will be used.
This may cause problems when your DNS server is IPv6-capable and
is returning IPv6 host addresses too. If IPv6 address
precedes IPv4 one in DNS reply, busybox network applets
(e.g. wget) will use IPv6 address. On an IPv6-incapable host
or network applets will fail to connect to the host
using IPv6 address.
config VERBOSE_RESOLUTION_ERRORS
bool "Verbose resolution errors"
default n
help
Enable if you are not satisfied with simplistic
"can't resolve 'hostname.com'" and want to know more.
This may increase size of your executable a bit.

"Range: bytes=NNN-[MMM]" header. Allows for resuming interrupted
downloads, seeking in multimedia players etc.
config FEATURE_HTTPD_USE_SENDFILE
bool "Use sendfile system call"
default n
depends on HTTPD
help
When enabled, httpd will use the kernel sendfile() function
instead of read/write loop.
config FEATURE_HTTPD_RELOAD_CONFIG_SIGHUP
bool "Support reloading the global config file using hup signal"
default n
depends on HTTPD
help
This option enables processing of SIGHUP to reload cached
configuration settings.
config FEATURE_HTTPD_SETUID
bool "Enable -u <user> option"
default n
depends on HTTPD
help
This option allows the server to run as a specific user
rather than defaulting to the user that starts the server.
Use of this option requires special privileges to change to a
different user.
config FEATURE_HTTPD_BASIC_AUTH
bool "Enable Basic http Authentication"
default y
depends on HTTPD
help
Utilizes password settings from /etc/httpd.conf for basic
authentication on a per url basis.
config FEATURE_HTTPD_AUTH_MD5

when specific URLs are requested.
config FEATURE_HTTPD_CONFIG_WITH_SCRIPT_INTERPR
bool "Enable support for running scripts through an interpreter"
default n
depends on FEATURE_HTTPD_CGI
help
This option enables support for running scripts through an
interpreter. Turn this on if you want PHP scripts to work
properly. You need to supply an additional line in your httpd
config file:
*.php:/path/to/your/php
config FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV
bool "Support the REMOTE_PORT environment variable for CGI"
default n
depends on FEATURE_HTTPD_CGI
help

references that contain a unique port number.
config FEATURE_HTTPD_ENCODE_URL_STR
bool "Enable the -e option for shell script CGI simplification."
default y
depends on HTTPD
help
This option allows html encoding arbitrary
strings for display of the browser. Output goes to stdout.
For example, httpd -e "<Hello World>" as
"&#60Hello&#32World&#62".
config FEATURE_HTTPD_ERROR_PAGES
bool "Enable support for custom error pages"
default n
depends on HTTPD
help
This option allows you to define custom error pages in
the configuration file instead of the default HTTP status
error pages. For instance, if you add the line:
E404:/path/e404.html
in the config file, the server will respond the specified
'/path/e404.html' file instead of the terse '404 NOT FOUND'
message.

and/or the interrupt line used by the specified device.
config FEATURE_IFCONFIG_HW
bool "Enable option \"hw\" (ether only)"
default y
depends on IFCONFIG
help
Set the hardware address of this interface, if the device driver
supports this operation. Currently, we only support the 'ether'
class.
config FEATURE_IFCONFIG_BROADCAST_PLUS
bool "Set the broadcast automatically"
default n
depends on IFCONFIG
help
Setting this will make ifconfig attempt to find the broadcast
automatically if the value '+' is used.
config IFUPDOWN
bool "ifupdown"
default n
help
Activate or deactivate the specified interfaces. This applet makes
use of either "ifconfig" and "route" or the "ip" command to actually
configure network interfaces. Therefore, you will probably also want
to enable either IFCONFIG and ROUTE, or enable
FEATURE_IFUPDOWN_IP and the various IP options. Of
course you could use non-busybox versions of these programs, so
against my better judgement (since this will surely result in plenty
of support questions on the mailing list), I do not force you to
enable these additional options. It is up to you to supply either
"ifconfig", "route" and "run-parts" or the "ip" command, either
via busybox or via standalone utilities.
config IFUPDOWN_IFSTATE_PATH
string "Absolute path to ifstate file"
default "/var/run/ifstate"
depends on IFUPDOWN
help
ifupdown keeps state information in a file called ifstate.
Typically it is located in /var/run/ifstate, however
some distributions tend to put it in other places
(debian, for example, uses /etc/network/run/ifstate).
This config option defines location of ifstate.
config FEATURE_IFUPDOWN_IP
bool "Use ip applet"
default n
depends on IFUPDOWN
help
Use the iproute "ip" command to implement "ifup" and "ifdown", rather
than the default of using the older 'ifconfig' and 'route' utilities.
config FEATURE_IFUPDOWN_IP_BUILTIN
bool "Use busybox ip applet"
default y
depends on FEATURE_IFUPDOWN_IP
select IP
select FEATURE_IP_ADDRESS
select FEATURE_IP_LINK
select FEATURE_IP_ROUTE
help
Use the busybox iproute "ip" applet to implement "ifupdown".
If left disabled, you must install the full-blown iproute2
utility or the "ifup" and "ifdown" applets will not work.
config FEATURE_IFUPDOWN_IFCONFIG_BUILTIN
bool "Use busybox ifconfig and route applets"
default y
depends on IFUPDOWN && !FEATURE_IFUPDOWN_IP
select IFCONFIG
select ROUTE
help
Use the busybox iproute "ifconfig" and "route" applets to
implement the "ifup" and "ifdown" utilities.
If left disabled, you must install the full-blown ifconfig
and route utilities, or the "ifup" and "ifdown" applets will not
work.

### networks.
config FEATURE_IFUPDOWN_MAPPING
bool "Enable mapping support"
default n
depends on IFUPDOWN
help
This enables support for the "mapping" stanza, unless you have
a weird network setup you don't need it.
config FEATURE_IFUPDOWN_EXTERNAL_DHCP
bool "Enable support for external dhcp clients"
default n
depends on IFUPDOWN
help
This enables support for the external dhcp clients. Clients are
tried in the following order: dhcpcd, dhclient, pump and udhcpc.
Otherwise, if udhcpc applet is enabled, it is used.
Otherwise, ifup/ifdown will have no support for DHCP.

config TELNETD
bool "telnetd"
default n
select FEATURE_SYSLOG
help
A daemon for the TELNET protocol, allowing you to log onto the host
running the daemon. Please keep in mind that the TELNET protocol
sends passwords in plain text. If you can't afford the space for an
SSH daemon and you trust your network, you may say 'y' here. As a
more secure alternative, you should seriously consider installing the
very small Dropbear SSH daemon instead:
http://matt.ucc.asn.au/dropbear/dropbear.html
Note that for busybox telnetd to work you need several things:
First of all, your kernel needs:
UNIX98_PTYS=y
DEVPTS_FS=y
Next, you need a /dev/pts directory on your root filesystem:
$ ls -ld /dev/pts
drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/
Next you need the pseudo terminal master multiplexer /dev/ptmx:
$ ls -la /dev/ptmx
crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
Any /dev/ttyp[0-9]* files you may have can be removed.
Next, you need to mount the devpts filesystem on /dev/pts using:
mount -t devpts devpts /dev/pts
You need to be sure that Busybox has LOGIN and
FEATURE_SUID enabled. And finally, you should make
certain that Busybox has been installed setuid root:
chown root.root /bin/busybox
chmod 4755 /bin/busybox
with all that done, telnetd _should_ work....
