	        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.

	help
	  Ifconfig is used to configure the kernel-resident network interfaces.

config FEATURE_IFCONFIG_STATUS

	  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.

	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.

config FEATURE_IFUPDOWN_IPV4

	depends on IFUPDOWN
	help
	  If you want ifup/ifdown to talk IPv4, leave this on.

### 	  networks.

	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.

	  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....
