config BUSYBOX_CONFIG_FEATURE_IPV6
bool "Enable IPv6 support"
default y
help
Enable IPv6 support in busybox.
This adds IPv6 support in the networking applets.
config BUSYBOX_CONFIG_FEATURE_UNIX_LOCAL
bool "Enable Unix domain socket support (usually not needed)"
default n
help
Enable Unix domain socket support in all busybox networking
applets. Address of the form local:/path/to/unix/socket
will be recognized.
This extension is almost never used in real world usage.
You most likely want to say N.
config BUSYBOX_CONFIG_FEATURE_PREFER_IPV4_ADDRESS
bool "Prefer IPv4 addresses from DNS queries"
default y
depends on BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_VERBOSE_RESOLUTION_ERRORS
bool "Verbose resolution errors"
default y
help

default y
depends on BUSYBOX_CONFIG_HTTPD
help
Makes httpd emit "Accept-Ranges: bytes" header and understand
"Range: bytes=NNN-[MMM]" header. Allows for resuming interrupted
downloads, seeking in multimedia players etc.
config BUSYBOX_CONFIG_FEATURE_HTTPD_USE_SENDFILE
bool "Use sendfile system call"
default n
depends on BUSYBOX_CONFIG_HTTPD

When enabled, httpd will use the kernel sendfile() function
instead of read/write loop.
config BUSYBOX_CONFIG_FEATURE_HTTPD_SETUID
bool "Enable -u <user> option"
default n
depends on BUSYBOX_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.

bool "Support for running scripts through an interpreter"
default y
depends on BUSYBOX_CONFIG_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:

"&#60Hello&#32World&#62".
config BUSYBOX_CONFIG_FEATURE_HTTPD_ERROR_PAGES
bool "Support for custom error pages"
default y
depends on BUSYBOX_CONFIG_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.
config BUSYBOX_CONFIG_FEATURE_HTTPD_PROXY
bool "Support for reverse proxy"
default y
depends on BUSYBOX_CONFIG_HTTPD
help
This option allows you to define URLs that will be forwarded
to another HTTP server. To setup add the following line to the
configuration file
P:/url/:http://hostname[:port]/new/path/
Then a request to /url/myfile will be forwarded to
http://hostname[:port]/new/path/myfile.
config BUSYBOX_CONFIG_IFCONFIG

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

of the currently active interfaces.
config BUSYBOX_CONFIG_FEATURE_IFCONFIG_SLIP
bool "Enable slip-specific options \"keepalive\" and \"outfill\""
default n
depends on BUSYBOX_CONFIG_IFCONFIG

planning on using serial lines, leave this unchecked.
config BUSYBOX_CONFIG_FEATURE_IFCONFIG_MEMSTART_IOADDR_IRQ

supports this operation. Currently, we only support the 'ether'
class.

automatically if the value '+' is used.
config BUSYBOX_CONFIG_IFENSLAVE

to a logical interface (use with kernel bonding driver).
config BUSYBOX_CONFIG_IFPLUGD
bool "ifplugd"
default n
help
Network interface plug detection daemon.
config BUSYBOX_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 BUSYBOX_CONFIG_IFUPDOWN_IFSTATE_PATH
string "Absolute path to ifstate file"
default n
depends on BUSYBOX_CONFIG_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 BUSYBOX_CONFIG_FEATURE_IFUPDOWN_IP
bool "Use ip applet"
default n
depends on BUSYBOX_CONFIG_IFUPDOWN

implement the "ifup" and "ifdown" utilities.

work.

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.

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....
