125 references that contain a unique port number.
127 config CONFIG_FEATURE_HTTPD_ENCODE_URL_STR
128 bool " Enable the -e option for shell script CGI simplification."
130 depends on CONFIG_HTTPD
132 After set, this option allows html encoding arbitrary
133 strings for display of the browser. Output goes to stdout.
134 For example, httpd -e "<Hello World>" as

137 config CONFIG_IFCONFIG
141 Ifconfig is used to configure the kernel-resident network interfaces.
143 config CONFIG_FEATURE_IFCONFIG_STATUS
144 bool " Enable status reporting output (+7k)"
146 depends on CONFIG_IFCONFIG
148 If ifconfig is called with no arguments it will display the status
149 of the currently active interfaces.
151 config CONFIG_FEATURE_IFCONFIG_SLIP
152 bool " Enable slip-specific options \"keepalive\" and \"outfill\""
154 depends on CONFIG_IFCONFIG

173 supports this operation. Currently, we only support the 'ether'
176 config CONFIG_FEATURE_IFCONFIG_BROADCAST_PLUS
177 bool " Set the broadcast automatically"
179 depends on CONFIG_IFCONFIG
181 Setting this will make ifconfig attempt to find the broadcast
182 automatically if the value '+' is used.
184 config CONFIG_IFUPDOWN
187 select CONFIG_RUN_PARTS
189 Activate or deactivate the specified interfaces. This applet makes
190 use of either "ifconfig" and "route" or the "ip" command to actually
191 configure network interfaces. Therefore, you will probably also want
192 to enable either CONFIG_IFCONFIG and CONFIG_ROUTE, or enable
193 CONFIG_FEATURE_IFUPDOWN_IP and the various CONFIG_IP options. Of
194 course you could use non-busybox versions of these programs, so
195 against my better judgement (since this will surely result in plenty
196 of support questions on the mailing list), I do not force you to
197 enable these additional options. It is up to you to supply either
198 "ifconfig" and "route" or the "ip" command, either via busybox or via
199 standalone utilities.
201 config CONFIG_FEATURE_IFUPDOWN_IP
202 bool " Use ip applet"
204 depends on CONFIG_IFUPDOWN
206 Use the iproute "ip" command to implement "ifup" and "ifdown", rather
207 than the default of using the older 'ifconfig' and 'route' utilities.

212 depends on CONFIG_FEATURE_IFUPDOWN_IP
214 select CONFIG_FEATURE_IP_ADDRESS
215 select CONFIG_FEATURE_IP_LINK
216 select CONFIG_FEATURE_IP_ROUTE
218 Use the busybox iproute "ip" applet to implement "ifupdown".
220 If leave this disabled, you must install the full-blown iproute2
221 utility or the "ifup" and "ifdown" applets will not work.
223 config CONFIG_FEATURE_IFUPDOWN_IP_BUILTIN
224 bool " Use busybox ifconfig and route applets"
226 depends on CONFIG_IFUPDOWN && !CONFIG_FEATURE_IFUPDOWN_IP
227 select CONFIG_IFCONFIG
230 Use the busybox iproute "ifconfig" and "route" applets to
231 implement the "ifup" and "ifdown" utilities.
233 If leave this disabled, you must install the full-blown ifconfig
234 and route utilities, or the "ifup" and "ifdown" applets will not
237 config CONFIG_FEATURE_IFUPDOWN_IPV4
238 bool " Enable support for IPv4"

445 successful connection (-e option).
447 config CONFIG_NETSTAT
451 netstat prints information about the Linux networking subsystem.
453 config CONFIG_NSLOOKUP
457 nslookup is a tool to query Internet name servers.
463 ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to
464 elicit an ICMP ECHO_RESPONSE from a host or gateway.
466 config CONFIG_FEATURE_FANCY_PING
467 bool " Enable fancy ping output"
469 depends on CONFIG_PING
471 Make the output from the ping applet include statistics, and at the
472 same time provide full support for ICMP packets.

500 used to test other simple protocols.
502 config CONFIG_FEATURE_TELNET_TTYPE
503 bool " Pass TERM type to remote host"
505 depends on CONFIG_TELNET
507 Setting this option will forward the TERM environment variable to the
508 remote host you are connecting to. This is useful to make sure that
509 things like ANSI colors and other control sequences behave.
511 config CONFIG_FEATURE_TELNET_AUTOLOGIN
512 bool " Pass USER type to remote host"
514 depends on CONFIG_TELNET
516 Setting this option will forward the USER environment variable to the
517 remote host you are connecting to. This is useful when you need to
518 log into a machine without telling the username (autologin). This
519 option enables `-a' and `-l USER' arguments.
521 config CONFIG_TELNETD
525 A daemon for the TELNET protocol, allowing you to log onto the host
526 running the daemon. Please keep in mind that the TELNET protocol
527 sends passwords in plain text. If you can't afford the space for an
528 SSH daemon and you trust your network, you may say 'y' here. As a
529 more secure alternative, you should seriously consider installing the
530 very small Dropbear SSH daemon instead:
531 http://matt.ucc.asn.au/dropbear/dropbear.html
533 Note that for busybox telnetd to work you need several things:
534 First of all, your kernel needs:
538 Next, you need a /dev/pts directory on your root filesystem:
541 drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/
543 Next you need the pseudo terminal master multiplexer /dev/ptmx:
546 crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
548 Any /dev/ttyp[0-9]* files you may have can be removed.
549 Next, you need to mount the devpts filesystem on /dev/pts using:
551 mount -t devpts devpts /dev/pts
553 You need to be sure that Busybox has CONFIG_LOGIN and
554 CONFIG_FEATURE_SUID enabled. And finally, you should make
555 certain that Busybox has been installed setuid root:
557 chown root.root /bin/busybox
558 chmod 4755 /bin/busybox
560 with all that done, telnetd _should_ work....
563 config CONFIG_FEATURE_TELNETD_INETD
564 bool " Support call from inetd only"
566 depends on CONFIG_TELNETD
568 Selecting this will make telnetd only callable from inetd,
569 removing the standalone support.
575 This enables the Trivial File Transfer Protocol client program. TFTP
576 is usually used for simple, small transfers such as a root image
577 for a network-enabled bootloader.
579 config CONFIG_FEATURE_TFTP_GET
580 bool " Enable \"get\" command"
582 depends on CONFIG_TFTP

585 a client to retrieve a file from a TFTP server.
587 config CONFIG_FEATURE_TFTP_PUT
588 bool " Enable \"put\" command"
590 depends on CONFIG_TFTP
592 Add support for the PUT command within the TFTP client. This allows

598 depends on CONFIG_TFTP
600 Allow the client to specify the desired block size for transfers.
602 config CONFIG_FEATURE_TFTP_DEBUG
605 depends on CONFIG_TFTP
607 Enable debug settings for tftp. This is useful if you're running

609 you run into problems.

615 Utility to trace the route of IP packets
617 config CONFIG_FEATURE_TRACEROUTE_VERBOSE
618 bool " Enable verbose output"
620 depends on CONFIG_TRACEROUTE

681 ZCIP provides ZeroConf IPv4 address selection, according to RFC 3927.
682 It's a daemon that allocates and defends a dynamically assigned
683 address on the 169.254/16 network, requiring no system administrator.
685 See http://www.zeroconf.org for further details, and "zcip.script"
686 in the busybox examples.
