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
135 "<Hello World>".
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.

152 bool " Enable slip-specific options \"keepalive\" and \"outfill\""
154 depends on CONFIG_IFCONFIG

168 bool " Enable option \"hw\" (ether only)"
170 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.

210 bool " Use busybox ip applet"
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"
240 depends on CONFIG_IFUPDOWN
242 If you want busybox to talk IPv4, leave this on.

438 successful connection (-e option).
440 config CONFIG_NETSTAT
444 netstat prints information about the Linux networking subsystem.
446 config CONFIG_NSLOOKUP
450 nslookup is a tool to query Internet name servers.
456 ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to
457 elicit an ICMP ECHO_RESPONSE from a host or gateway.
459 config CONFIG_FEATURE_FANCY_PING
460 bool " Enable fancy ping output"
462 depends on CONFIG_PING
464 Make the output from the ping applet include statistics, and at the
465 same time provide full support for ICMP packets.
470 depends on CONFIG_FEATURE_IPV6
472 This will give you a ping that can talk IPv6.
474 config CONFIG_FEATURE_FANCY_PING6

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

578 a client to retrieve a file from a TFTP server.
580 config CONFIG_FEATURE_TFTP_PUT
581 bool " Enable \"put\" command"
583 depends on CONFIG_TFTP
585 Add support for the PUT command within the TFTP client. This allows
586 a client to transfer a file to a TFTP server.

591 depends on CONFIG_TFTP
593 Allow the client to specify the desired block size for transfers.
595 config CONFIG_FEATURE_TFTP_DEBUG
598 depends on CONFIG_TFTP
600 Enable debug settings for tftp. This is useful if you're running
601 into problems with tftp as the protocol doesn't help you much when
602 you run into problems.

608 Utility to trace the route of IP packets
610 config CONFIG_FEATURE_TRACEROUTE_VERBOSE
611 bool " Enable verbose output"
613 depends on CONFIG_TRACEROUTE

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