default n
depends on CONFIG_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.
endif
config CONFIG_FEATURE_HTTPD_CONFIG_WITH_MIME_TYPES
bool " Support loading additional MIME types at run-time"
default n
depends on CONFIG_HTTPD
help
This option enables support for additional MIME types at
run-time to be specified in the configuration file.

default n
depends on CONFIG_IFCONFIG
help
Setting this will make ifconfig attempt to find the broadcast
automatically if the value '+' is used.
config 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 CONFIG_IFCONFIG and CONFIG_ROUTE, or enable
CONFIG_FEATURE_IFUPDOWN_IP and the various CONFIG_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" and "route" or the "ip" command, either via busybox or via
standalone utilities.
config CONFIG_FEATURE_IFUPDOWN_IP
bool " Use ip applet"
default n
depends on CONFIG_IFUPDOWN
help
Use the iproute "ip" command to implement "ifup" and "ifdown", rather
than the default of using the older 'ifconfig' and 'route' utilities.

default y
depends on CONFIG_FEATURE_IFUPDOWN_IP
select CONFIG_IP
select CONFIG_FEATURE_IP_ADDRESS
select CONFIG_FEATURE_IP_LINK
select CONFIG_FEATURE_IP_ROUTE
help
Use the busybox iproute "ip" applet to implement "ifupdown".
If leave this disabled, you must install the full-blown iproute2
utility or the "ifup" and "ifdown" applets will not work.
config CONFIG_FEATURE_IFUPDOWN_IP_BUILTIN
bool " Use busybox ifconfig and route applets"
default y
depends on CONFIG_IFUPDOWN && !CONFIG_FEATURE_IFUPDOWN_IP
select CONFIG_IFCONFIG
select CONFIG_ROUTE
help
Use the busybox iproute "ifconfig" and "route" applets to
implement the "ifup" and "ifdown" utilities.
If leave this disabled, you must install the full-blown ifconfig
and route utilities, or the "ifup" and "ifdown" applets will not
work.
config CONFIG_FEATURE_IFUPDOWN_IPV4
bool " Enable support for IPv4"
default y
depends on CONFIG_IFUPDOWN
help
If you want busybox to talk IPv4, leave this on.
config CONFIG_FEATURE_IFUPDOWN_IPV6

help
If you need support for IPv6, turn this option on.
config CONFIG_FEATURE_IFUPDOWN_IPX

a weird network setup you don't need it.

config CONFIG_IP

resulting broadcast, network, and host range.
config CONFIG_FEATURE_IPCALC_FANCY

elicit an ICMP ECHO_RESPONSE from a host or gateway.
config CONFIG_FEATURE_FANCY_PING
bool " Enable fancy ping output"
default y
depends on CONFIG_PING
help

same time provide full support for ICMP packets.
config CONFIG_PING6

This will give you a ping that can talk IPv6.
config CONFIG_FEATURE_FANCY_PING6

used to test other simple protocols.
config CONFIG_FEATURE_TELNET_TTYPE

remote host you are connecting to. This is useful to make sure that
things like ANSI colors and other control sequences behave.
config CONFIG_FEATURE_TELNET_AUTOLOGIN
bool " Pass USER type to remote host"
default y
depends on CONFIG_TELNET
help
Setting this option will forward the USER environment variable to the
remote host you are connecting to. This is useful when you need to

config CONFIG_TELNETD
bool "telnetd"
default n
select CONFIG_LOGIN
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:
CONFIG_UNIX98_PTYS=y
CONFIG_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 CONFIG_LOGIN and
CONFIG_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....
config CONFIG_FEATURE_TELNETD_INETD
bool " Support call from inetd only"
default n
depends on CONFIG_TELNETD
help
Selecting this will make telnetd only callable from inetd,
removing the standalone support.
config CONFIG_TFTP
