Renamed interfaces MUST be in the down state. It is possible to use a file (default: /etc/mactab) with list of new interface names and MACs. Maximum interface name length: IFNAMSIZ = 16 File fields are separated by space or tab. File format: # Comment new_interface_name XX:XX:XX:XX:XX:XX config BUSYBOX_FEATURE_NAMEIF_EXTENDED bool "Extended nameif" default y depends on BUSYBOX_NAMEIF help This extends the nameif syntax to support the bus_info, driver, phyaddr selectors. The syntax is compatible to the normal nameif. File format: new_interface_name driver=asix bus=usb-0000:00:08.2-3 new_interface_name bus=usb-0000:00:08.2-3 00:80:C8:38:91:B5 new_interface_name phy_address=2 00:80:C8:38:91:B5 new_interface_name mac=00:80:C8:38:91:B5 new_interface_name 00:80:C8:38:91:B5 config BUSYBOX_NBDCLIENT bool "nbd-client" default n help Network block device client config BUSYBOX_NC bool "nc" default n help A simple Unix utility which reads and writes data across network connections. config BUSYBOX_NC_SERVER bool "Netcat server options (-l)" default y depends on BUSYBOX_NC help Allow netcat to act as a server. config BUSYBOX_NC_EXTRA bool "Netcat extensions (-eiw and filename)" default y depends on BUSYBOX_NC help Add -e (support for executing the rest of the command line after making or receiving a successful connection), -i (delay interval for lines sent), -w (timeout for initial connection). config BUSYBOX_NC_110_COMPAT bool "Netcat 1.10 compatibility (+2.5k)" default n # off specially for Rob depends on BUSYBOX_NC help This option makes nc closely follow original nc-1.10. The code is about 2.5k bigger. It enables -s ADDR, -n, -u, -v, -o FILE, -z options, but loses busybox-specific extensions: -f FILE and -ll. config BUSYBOX_PING bool "ping" default y if ADK_TARGET_WITH_NET select BUSYBOX_PLATFORM_LINUX help ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to elicit an ICMP ECHO_RESPONSE from a host or gateway. config BUSYBOX_PING6 bool "ping6" default y if ADK_TARGET_WITH_NET depends on BUSYBOX_FEATURE_IPV6 && BUSYBOX_PING help This will give you a ping that can talk IPv6. config BUSYBOX_FEATURE_FANCY_PING bool "Enable fancy ping output" default y depends on BUSYBOX_PING help Make the output from the ping applet include statistics, and at the same time provide full support for ICMP packets. config BUSYBOX_WHOIS bool "whois" default n help whois is a client for the whois directory service config BUSYBOX_FEATURE_IPV6 bool "Enable IPv6 support" default n help Enable IPv6 support in busybox. This adds IPv6 support in the networking applets. config BUSYBOX_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_FEATURE_PREFER_IPV4_ADDRESS bool "Prefer IPv4 addresses from DNS queries" default y depends on BUSYBOX_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_VERBOSE_RESOLUTION_ERRORS bool "Verbose resolution errors" default n help Enable if you are not satisfied with simplistic "can't resolve 'hostname.com'" and want to know more. This may increase size of your executable a bit. config BUSYBOX_ARP bool "arp" default n select BUSYBOX_PLATFORM_LINUX help Manipulate the system ARP cache. config BUSYBOX_ARPING bool "arping" default n select BUSYBOX_PLATFORM_LINUX help Ping hosts by ARP packets. config BUSYBOX_BRCTL bool "brctl" depends on !BUSYBOX_DISABLE_BRCTL default n select BUSYBOX_PLATFORM_LINUX help Manage ethernet bridges. Supports addbr/delbr and addif/delif. config BUSYBOX_FEATURE_BRCTL_FANCY bool "Fancy options" default y depends on BUSYBOX_BRCTL help Add support for extended option like: setageing, setfd, sethello, setmaxage, setpathcost, setportprio, setbridgeprio, stp This adds about 600 bytes. config BUSYBOX_FEATURE_BRCTL_SHOW bool "Support show, showmac and showstp" default y depends on BUSYBOX_BRCTL && BUSYBOX_FEATURE_BRCTL_FANCY help Add support for option which prints the current config: showmacs, showstp, show config BUSYBOX_DNSD bool "dnsd" default n help Small and static DNS server daemon. config BUSYBOX_ETHER_WAKE bool "ether-wake" depends on !BUSYBOX_DISABLE_ETHER_WAKE default n select BUSYBOX_PLATFORM_LINUX help Send a magic packet to wake up sleeping machines. config BUSYBOX_FAKEIDENTD bool "fakeidentd" default n select BUSYBOX_FEATURE_SYSLOG help fakeidentd listens on the ident port and returns a predefined fake value on any query. config BUSYBOX_FTPD bool "ftpd" default n help simple FTP daemon. You have to run it via inetd. config BUSYBOX_FEATURE_FTP_WRITE bool "Enable upload commands" default y depends on BUSYBOX_FTPD help Enable all kinds of FTP upload commands (-w option) config BUSYBOX_FEATURE_FTPD_ACCEPT_BROKEN_LIST bool "Enable workaround for RFC-violating clients" default y depends on BUSYBOX_FTPD help Some ftp clients (among them KDE's Konqueror) issue illegal "LIST -l" requests. This option works around such problems. It might prevent you from listing files starting with "-" and it increases the code size by ~40 bytes. Most other ftp servers seem to behave similar to this. config BUSYBOX_FTPGET bool "ftpget" default n help Retrieve a remote file via FTP. config BUSYBOX_FTPPUT bool "ftpput" default n help Store a remote file via FTP. config BUSYBOX_FEATURE_FTPGETPUT_LONG_OPTIONS bool "Enable long options in ftpget/ftpput" default y depends on BUSYBOX_LONG_OPTS && (BUSYBOX_FTPGET || BUSYBOX_FTPPUT) help Support long options for the ftpget/ftpput applet. config BUSYBOX_HOSTNAME bool "hostname" default y help Show or set the system's host name. config BUSYBOX_HTTPD bool "httpd" default n help Serve web pages via an HTTP server. config BUSYBOX_FEATURE_HTTPD_RANGES bool "Support 'Ranges:' header" default y depends on BUSYBOX_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_FEATURE_HTTPD_USE_SENDFILE bool "Use sendfile system call" default y depends on BUSYBOX_HTTPD help When enabled, httpd will use the kernel sendfile() function instead of read/write loop. config BUSYBOX_FEATURE_HTTPD_SETUID bool "Enable -u option" default y depends on BUSYBOX_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. config BUSYBOX_FEATURE_HTTPD_BASIC_AUTH bool "Enable Basic http Authentication" default y depends on BUSYBOX_HTTPD help Utilizes password settings from /etc/httpd.conf for basic authentication on a per url basis. Example for httpd.conf file: /adm:toor:PaSsWd config BUSYBOX_FEATURE_HTTPD_AUTH_MD5 bool "Support MD5 crypted passwords for http Authentication" default y depends on BUSYBOX_FEATURE_HTTPD_BASIC_AUTH help Enables encrypted passwords, and wildcard user/passwords in httpd.conf file. User '*' means 'any system user name is ok', password of '*' means 'use system password for this user' Examples: /adm:toor:$1$P/eKnWXS$aI1aPGxT.dJD5SzqAKWrF0 /adm:root:* /wiki:*:* config BUSYBOX_FEATURE_HTTPD_CGI bool "Support Common Gateway Interface (CGI)" default y depends on BUSYBOX_HTTPD help This option allows scripts and executables to be invoked when specific URLs are requested. config BUSYBOX_FEATURE_HTTPD_CONFIG_WITH_SCRIPT_INTERPR bool "Support for running scripts through an interpreter" default y depends on BUSYBOX_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.conf file: *.php:/path/to/your/php config BUSYBOX_FEATURE_HTTPD_SET_REMOTE_PORT_TO_ENV bool "Set REMOTE_PORT environment variable for CGI" default y depends on BUSYBOX_FEATURE_HTTPD_CGI help Use of this option can assist scripts in generating references that contain a unique port number. config BUSYBOX_FEATURE_HTTPD_ENCODE_URL_STR bool "Enable -e option (useful for CGIs written as shell scripts)" default y depends on BUSYBOX_HTTPD help This option allows html encoding of arbitrary strings for display by the browser. Output goes to stdout. For example, httpd -e "" produces "<Hello World>". config BUSYBOX_FEATURE_HTTPD_ERROR_PAGES bool "Support for custom error pages" default y depends on BUSYBOX_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_FEATURE_HTTPD_PROXY bool "Support for reverse proxy" default y depends on BUSYBOX_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_FEATURE_HTTPD_GZIP bool "Support for GZIP content encoding" default y depends on BUSYBOX_HTTPD help Makes httpd send files using GZIP content encoding if the client supports it and a pre-compressed .gz exists. config BUSYBOX_IFCONFIG bool "ifconfig" default y if ADK_TARGET_WITH_NET select BUSYBOX_PLATFORM_LINUX help Ifconfig is used to configure the kernel-resident network interfaces. config BUSYBOX_FEATURE_IFCONFIG_STATUS bool "Enable status reporting output (+7k)" default y depends on BUSYBOX_IFCONFIG help If ifconfig is called with no arguments it will display the status of the currently active interfaces. config BUSYBOX_FEATURE_IFCONFIG_SLIP bool "Enable slip-specific options \"keepalive\" and \"outfill\"" default n depends on BUSYBOX_IFCONFIG help Allow "keepalive" and "outfill" support for SLIP. If you're not planning on using serial lines, leave this unchecked. config BUSYBOX_FEATURE_IFCONFIG_MEMSTART_IOADDR_IRQ bool "Enable options \"mem_start\", \"io_addr\", and \"irq\"" default n depends on BUSYBOX_IFCONFIG help Allow the start address for shared memory, start address for I/O, and/or the interrupt line used by the specified device. config BUSYBOX_FEATURE_IFCONFIG_HW bool "Enable option \"hw\" (ether only)" default y depends on BUSYBOX_IFCONFIG help Set the hardware address of this interface, if the device driver supports this operation. Currently, we only support the 'ether' class. config BUSYBOX_FEATURE_IFCONFIG_BROADCAST_PLUS bool "Set the broadcast automatically" default y depends on BUSYBOX_IFCONFIG help Setting this will make ifconfig attempt to find the broadcast automatically if the value '+' is used. config BUSYBOX_IFENSLAVE bool "ifenslave" select ADK_KERNEL_BONDING m default n select BUSYBOX_PLATFORM_LINUX help Userspace application to bind several interfaces to a logical interface (use with kernel bonding driver). config BUSYBOX_IFPLUGD bool "ifplugd" default n select BUSYBOX_PLATFORM_LINUX help Network interface plug detection daemon. config BUSYBOX_IFUPDOWN bool "ifupdown" default y if ADK_TARGET_WITH_NET 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_IFUPDOWN_IFSTATE_PATH string "Absolute path to ifstate file" default "/var/run/ifstate" depends on BUSYBOX_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_FEATURE_IFUPDOWN_IP bool "Use ip applet" default y depends on BUSYBOX_IFUPDOWN help Use the iproute "ip" command to implement "ifup" and "ifdown", rather than the default of using the older 'ifconfig' and 'route' utilities. config BUSYBOX_FEATURE_IFUPDOWN_IP_BUILTIN bool "Use busybox ip applet" default y if !BUSYBOX_DISABLE_IP depends on BUSYBOX_FEATURE_IFUPDOWN_IP select BUSYBOX_PLATFORM_LINUX select BUSYBOX_IP select BUSYBOX_FEATURE_IP_ADDRESS select BUSYBOX_FEATURE_IP_LINK select BUSYBOX_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 BUSYBOX_FEATURE_IFUPDOWN_IFCONFIG_BUILTIN bool "Use busybox ifconfig and route applets" default n depends on BUSYBOX_IFUPDOWN && !BUSYBOX_FEATURE_IFUPDOWN_IP select BUSYBOX_IFCONFIG select BUSYBOX_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 BUSYBOX_FEATURE_IFUPDOWN_IPV4 bool "Support for IPv4" default y depends on BUSYBOX_IFUPDOWN help If you want ifup/ifdown to talk IPv4, leave this on. config BUSYBOX_FEATURE_IFUPDOWN_IPV6 bool "Support for IPv6" default y depends on BUSYBOX_IFUPDOWN && BUSYBOX_FEATURE_IPV6 help If you need support for IPv6, turn this option on. ### UNUSED ###config FEATURE_IFUPDOWN_IPX ### bool "Support for IPX" ### default y ### depends on BUSYBOX_IFUPDOWN ### help ### If this option is selected you can use busybox to work with IPX ### networks. config BUSYBOX_FEATURE_IFUPDOWN_MAPPING bool "Enable mapping support" default n depends on BUSYBOX_IFUPDOWN help This enables support for the "mapping" stanza, unless you have a weird network setup you don't need it. config BUSYBOX_FEATURE_IFUPDOWN_EXTERNAL_DHCP bool "Support for external dhcp clients" default n depends on BUSYBOX_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. config BUSYBOX_INETD bool "inetd" default n select BUSYBOX_FEATURE_SYSLOG help Internet superserver daemon config BUSYBOX_FEATURE_INETD_SUPPORT_BUILTIN_ECHO bool "Support echo service" default y depends on BUSYBOX_INETD help Echo received data internal inetd service config BUSYBOX_FEATURE_INETD_SUPPORT_BUILTIN_DISCARD bool "Support discard service" default y depends on BUSYBOX_INETD help Internet /dev/null internal inetd service config BUSYBOX_FEATURE_INETD_SUPPORT_BUILTIN_TIME bool "Support time service" default y depends on BUSYBOX_INETD help Return 32 bit time since 1900 internal inetd service config BUSYBOX_FEATURE_INETD_SUPPORT_BUILTIN_DAYTIME bool "Support daytime service" default y depends on BUSYBOX_INETD help Return human-readable time internal inetd service config BUSYBOX_FEATURE_INETD_SUPPORT_BUILTIN_CHARGEN bool "Support chargen service" default y depends on BUSYBOX_INETD help Familiar character generator internal inetd service config BUSYBOX_FEATURE_INETD_RPC bool "Support RPC services" default n depends on BUSYBOX_INETD select BUSYBOX_FEATURE_HAVE_RPC help Support Sun-RPC based services config BUSYBOX_IP bool "ip" depends on !BUSYBOX_DISABLE_IP default y if ADK_TARGET_WITH_NET select BUSYBOX_PLATFORM_LINUX help The "ip" applet is a TCP/IP interface configuration and routing utility. You generally don't need "ip" to use busybox with TCP/IP. config BUSYBOX_FEATURE_IP_ADDRESS bool "ip address" default y depends on BUSYBOX_IP help Address manipulation support for the "ip" applet. config BUSYBOX_FEATURE_IP_LINK bool "ip link" default y depends on BUSYBOX_IP help Configure network devices with "ip". config BUSYBOX_FEATURE_IP_ROUTE bool "ip route" default y depends on BUSYBOX_IP help Add support for routing table management to "ip". config BUSYBOX_FEATURE_IP_ROUTE_DIR string "ip route configuration directory" default "/etc/iproute2" depends on BUSYBOX_FEATURE_IP_ROUTE help Location of the "ip" applet routing configuration. config BUSYBOX_FEATURE_IP_TUNNEL bool "ip tunnel" default n depends on BUSYBOX_IP help Add support for tunneling commands to "ip". config BUSYBOX_FEATURE_IP_RULE bool "ip rule" default n depends on BUSYBOX_IP help Add support for rule commands to "ip". config BUSYBOX_FEATURE_IP_SHORT_FORMS bool "Support short forms of ip commands" default n depends on BUSYBOX_IP help Also support short-form of ip commands: ip addr -> ipaddr ip link -> iplink ip route -> iproute ip tunnel -> iptunnel ip rule -> iprule Say N unless you desparately need the short form of the ip object commands. config BUSYBOX_FEATURE_IP_RARE_PROTOCOLS bool "Support displaying rarely used link types" default n depends on BUSYBOX_IP help If you are not going to use links of type "frad", "econet", "bif" etc, you probably don't need to enable this. Ethernet, wireless, infrared, ppp/slip, ip tunnelling link types are supported without this option selected. config BUSYBOX_IPADDR bool default n depends on BUSYBOX_FEATURE_IP_SHORT_FORMS && BUSYBOX_FEATURE_IP_ADDRESS config BUSYBOX_IPLINK bool default n depends on BUSYBOX_FEATURE_IP_SHORT_FORMS && BUSYBOX_FEATURE_IP_LINK config BUSYBOX_IPROUTE bool default n depends on BUSYBOX_FEATURE_IP_SHORT_FORMS && BUSYBOX_FEATURE_IP_ROUTE config BUSYBOX_IPTUNNEL bool default n depends on BUSYBOX_FEATURE_IP_SHORT_FORMS && BUSYBOX_FEATURE_IP_TUNNEL config BUSYBOX_IPRULE bool default n depends on BUSYBOX_FEATURE_IP_SHORT_FORMS && BUSYBOX_FEATURE_IP_RULE config BUSYBOX_IPCALC bool "ipcalc" default n help ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, and host range. config BUSYBOX_FEATURE_IPCALC_FANCY bool "Fancy IPCALC, more options, adds 1 kbyte" default y depends on BUSYBOX_IPCALC help Adds the options hostname, prefix and silent to the output of "ipcalc". config BUSYBOX_FEATURE_IPCALC_LONG_OPTIONS bool "Enable long options" default y depends on BUSYBOX_IPCALC && BUSYBOX_LONG_OPTS help Support long options for the ipcalc applet. config BUSYBOX_NETSTAT bool "netstat" default y if ADK_TARGET_WITH_NET select BUSYBOX_PLATFORM_LINUX help netstat prints information about the Linux networking subsystem. config BUSYBOX_FEATURE_NETSTAT_WIDE bool "Enable wide netstat output" default n depends on BUSYBOX_NETSTAT help Add support for wide columns. Useful when displaying IPv6 addresses (-W option). config BUSYBOX_FEATURE_NETSTAT_PRG bool "Enable PID/Program name output" default y depends on BUSYBOX_NETSTAT help Add support for -p flag to print out PID and program name. +700 bytes of code. config BUSYBOX_NSLOOKUP bool "nslookup" default y if ADK_TARGET_WITH_NET help nslookup is a tool to query Internet name servers. config BUSYBOX_NTPD bool "ntpd" depends on !BUSYBOX_DISABLE_NTPD default n select BUSYBOX_PLATFORM_LINUX help The NTP client/server daemon. config BUSYBOX_FEATURE_NTPD_SERVER bool "Make ntpd usable as a NTP server" default n depends on !BUSYBOX_DISABLE_NTPD depends on BUSYBOX_NTPD help Make ntpd usable as a NTP server. If you disable this option ntpd will be usable only as a NTP client. config BUSYBOX_FEATURE_NTPD_CONF bool "Make ntpd understand /etc/ntp.conf" default n depends on BUSYBOX_NTPD help Make ntpd look in /etc/ntp.conf for peers. Only "server address" is supported. config BUSYBOX_PSCAN bool "pscan" default n help Simple network port scanner. config BUSYBOX_ROUTE bool "route" default y if ADK_TARGET_WITH_NET select BUSYBOX_PLATFORM_LINUX help Route displays or manipulates the kernel's IP routing tables. config BUSYBOX_SLATTACH bool "slattach" default n select BUSYBOX_PLATFORM_LINUX help slattach is a small utility to attach network interfaces to serial lines. #config TC # bool "tc" # default y # help # show / manipulate traffic control settings # #config FEATURE_TC_INGRESS # def_bool n # depends on BUSYBOX_TC config BUSYBOX_TCPSVD bool "tcpsvd" default n help tcpsvd listens on a TCP port and runs a program for each new connection. config BUSYBOX_TELNET bool "telnet" default y if ADK_TARGET_WITH_NET help Telnet is an interface to the TELNET protocol, but is also commonly used to test other simple protocols. config BUSYBOX_FEATURE_TELNET_TTYPE bool "Pass TERM type to remote host" default y depends on BUSYBOX_TELNET help Setting this option will forward the TERM environment variable to the remote host you are connecting to. This is useful to make sure that things like ANSI colors and other control sequences behave. config BUSYBOX_FEATURE_TELNET_AUTOLOGIN bool "Pass USER type to remote host" default y depends on BUSYBOX_TELNET help Setting this option will forward the USER environment variable to the remote host you are connecting to. This is useful when you need to log into a machine without telling the username (autologin). This option enables `-a' and `-l USER' arguments. config BUSYBOX_TELNETD bool "telnetd" default n select BUSYBOX_FEATURE_SYSLOG 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: 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.... config BUSYBOX_FEATURE_TELNETD_STANDALONE bool "Support standalone telnetd (not inetd only)" default y depends on BUSYBOX_TELNETD help Selecting this will make telnetd able to run standalone. config BUSYBOX_FEATURE_TELNETD_INETD_WAIT bool "Support -w SEC option (inetd wait mode)" default y depends on BUSYBOX_FEATURE_TELNETD_STANDALONE help This option allows you to run telnetd in "inet wait" mode. Example inetd.conf line (note "wait", not usual "nowait"): telnet stream tcp wait root /bin/telnetd telnetd -w10 In this example, inetd passes _listening_ socket_ as fd 0 to telnetd when connection appears. telnetd will wait for connections until all existing connections are closed, and no new connections appear during 10 seconds. Then it exits, and inetd continues to listen for new connections. This option is rarely used. "tcp nowait" is much more usual way of running tcp services, including telnetd. You most probably want to say N here. config BUSYBOX_TFTP bool "tftp" default n help This enables the Trivial File Transfer Protocol client program. TFTP is usually used for simple, small transfers such as a root image for a network-enabled bootloader. config BUSYBOX_TFTPD bool "tftpd" default n help This enables the Trivial File Transfer Protocol server program. It expects that stdin is a datagram socket and a packet is already pending on it. It will exit after one transfer. In other words: it should be run from inetd in nowait mode, or from udpsvd. Example: "udpsvd -E 0 69 tftpd DIR" comment "Common options for tftp/tftpd" depends on BUSYBOX_TFTP || BUSYBOX_TFTPD config BUSYBOX_FEATURE_TFTP_GET bool "Enable 'tftp get' and/or tftpd upload code" default y depends on BUSYBOX_TFTP || BUSYBOX_TFTPD help Add support for the GET command within the TFTP client. This allows a client to retrieve a file from a TFTP server. Also enable upload support in tftpd, if tftpd is selected. Note: this option does _not_ make tftpd capable of download (the usual operation people need from it)! config BUSYBOX_FEATURE_TFTP_PUT bool "Enable 'tftp put' and/or tftpd download code" default y depends on BUSYBOX_TFTP || BUSYBOX_TFTPD help Add support for the PUT command within the TFTP client. This allows a client to transfer a file to a TFTP server. Also enable download support in tftpd, if tftpd is selected. config BUSYBOX_FEATURE_TFTP_BLOCKSIZE bool "Enable 'blksize' and 'tsize' protocol options" default y depends on BUSYBOX_TFTP || BUSYBOX_TFTPD help Allow tftp to specify block size, and tftpd to understand "blksize" and "tsize" options. config BUSYBOX_FEATURE_TFTP_PROGRESS_BAR bool "Enable tftp progress meter" default y depends on BUSYBOX_TFTP && BUSYBOX_FEATURE_TFTP_BLOCKSIZE help Show progress bar. config BUSYBOX_TFTP_DEBUG bool "Enable debug" default n depends on BUSYBOX_TFTP || BUSYBOX_TFTPD help Make tftp[d] print debugging messages on stderr. This is useful if you are diagnosing a bug in tftp[d]. config BUSYBOX_TRACEROUTE bool "traceroute" default n select BUSYBOX_PLATFORM_LINUX help Utility to trace the route of IP packets. config BUSYBOX_TRACEROUTE6 bool "traceroute6" default n depends on BUSYBOX_FEATURE_IPV6 && BUSYBOX_TRACEROUTE help Utility to trace the route of IPv6 packets. config BUSYBOX_FEATURE_TRACEROUTE_VERBOSE bool "Enable verbose output" default y depends on BUSYBOX_TRACEROUTE help Add some verbosity to traceroute. This includes among other things hostnames and ICMP response types. config BUSYBOX_FEATURE_TRACEROUTE_SOURCE_ROUTE bool "Enable loose source route" default n depends on BUSYBOX_TRACEROUTE help Add option to specify a loose source route gateway (8 maximum). config BUSYBOX_FEATURE_TRACEROUTE_USE_ICMP bool "Use ICMP instead of UDP" default n depends on BUSYBOX_TRACEROUTE help Add option -I to use ICMP ECHO instead of UDP datagrams. config BUSYBOX_TUNCTL bool "tunctl" default n select BUSYBOX_PLATFORM_LINUX help tunctl creates or deletes tun devices. config BUSYBOX_FEATURE_TUNCTL_UG bool "Support owner:group assignment" default y depends on BUSYBOX_TUNCTL help Allow to specify owner and group of newly created interface. 340 bytes of pure bloat. Say no here. source package/busybox/config/networking/udhcp/Config.in config BUSYBOX_IFUPDOWN_UDHCPC_CMD_OPTIONS string "ifup udhcpc command line options" default "-R" if BUSYBOX_NOMMU default "-R -b" depends on BUSYBOX_IFUPDOWN && BUSYBOX_UDHCPC help Command line options to pass to udhcpc from ifup. Intended to alter options not available in /etc/network/interfaces. (IE: --syslog --background etc...) config BUSYBOX_UDPSVD bool "udpsvd" default n help udpsvd listens on an UDP port and runs a program for each new connection. config BUSYBOX_VCONFIG bool "vconfig" default n select BUSYBOX_PLATFORM_LINUX help Creates, removes, and configures VLAN interfaces config BUSYBOX_WGET bool "wget" depends on !BUSYBOX_DISABLE_WGET default n help wget is a utility for non-interactive download of files from HTTP, HTTPS, and FTP servers. config BUSYBOX_FEATURE_WGET_STATUSBAR bool "Enable a nifty process meter (+2k)" default n depends on BUSYBOX_WGET help Enable the transfer progress bar for wget transfers. config BUSYBOX_FEATURE_WGET_AUTHENTICATION bool "Enable HTTP authentication" default y depends on BUSYBOX_WGET help Support authenticated HTTP transfers. config BUSYBOX_FEATURE_WGET_LONG_OPTIONS bool "Enable long options" default y depends on BUSYBOX_WGET && BUSYBOX_LONG_OPTS help Support long options for the wget applet. config BUSYBOX_FEATURE_WGET_TIMEOUT bool "Enable read timeout option -T SEC" default y depends on BUSYBOX_WGET help Supports network read timeout for wget, so that wget will give up and timeout when reading network data, through the -T command line option. Currently only network data read timeout is supported (i.e., timeout is not applied to the DNS nor TCP connection initialization). When FEATURE_WGET_LONG_OPTIONS is also enabled, the --timeout option will work in addition to -T. config BUSYBOX_FEATURE_WGET_OPENSSL bool "Try to connect to HTTPS using openssl" default n depends on BUSYBOX_WGET help Choose how wget establishes SSL connection for https:// URLs. Busybox itself contains no SSL code. wget will spawn a helper program to talk over HTTPS. OpenSSL has a simple SSL client for debug purposes. If you select "openssl" helper, wget will effectively call "openssl s_client -quiet -connect IP:443 2>/dev/null" and pipe its data through it. Note inconvenient API: host resolution is done twice, and there is no guarantee openssl's idea of IPv6 address format is the same as ours. Another problem is that s_client prints debug information to stderr, and it needs to be suppressed. This means all error messages get suppressed too. openssl is also a big binary, often dynamically linked against ~15 libraries. config BUSYBOX_FEATURE_WGET_SSL_HELPER bool "Try to connect to HTTPS using ssl_helper" default n depends on BUSYBOX_WGET help Choose how wget establishes SSL connection for https:// URLs. Busybox itself contains no SSL code. wget will spawn a helper program to talk over HTTPS. ssl_helper is a tool which can be built statically from busybox sources against a small embedded SSL library. Please see networking/ssl_helper/README. It does not require double host resolution and emits error messages to stderr. Precompiled static binary may be available at http://busybox.net/downloads/binaries/ config BUSYBOX_ZCIP bool "zcip" default n select BUSYBOX_PLATFORM_LINUX select BUSYBOX_FEATURE_SYSLOG help ZCIP provides ZeroConf IPv4 address selection, according to RFC 3927. It's a daemon that allocates and defends a dynamically assigned address on the 169.254/16 network, requiring no system administrator. See http://www.zeroconf.org for further details, and "zcip.script" in the busybox examples. endmenu
