help
Setting this will make ifconfig attempt to find the broadcast
automatically if the value '+' is used.
config CONFIG_IFUPDOWN
bool "ifupdown"
default n
select CONFIG_RUN_PARTS
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

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

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

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

removing the standalone support.
