207 select BUSYBOX_CONFIG_RUN_PARTS
209 Activate or deactivate the specified interfaces. This applet makes
210 use of either "ifconfig" and "route" or the "ip" command to actually
211 configure network interfaces. Therefore, you will probably also want
212 to enable either IFCONFIG and ROUTE, or enable
213 FEATURE_IFUPDOWN_IP and the various IP options. Of
214 course you could use non-busybox versions of these programs, so
215 against my better judgement (since this will surely result in plenty
216 of support questions on the mailing list), I do not force you to
217 enable these additional options. It is up to you to supply either
218 "ifconfig" and "route" or the "ip" command, either via busybox or via
219 standalone utilities.
221 config BUSYBOX_CONFIG_FEATURE_IFUPDOWN_IP
224 depends on BUSYBOX_CONFIG_IFUPDOWN

238 Use the busybox iproute "ip" applet to implement "ifupdown".
240 If left disabled, you must install the full-blown iproute2
241 utility or the "ifup" and "ifdown" applets will not work.

555 log into a machine without telling the username (autologin). This
556 option enables `-a' and `-l USER' arguments.
558 config BUSYBOX_CONFIG_TELNETD
561 select BUSYBOX_CONFIG_FEATURE_SYSLOG
563 A daemon for the TELNET protocol, allowing you to log onto the host
564 running the daemon. Please keep in mind that the TELNET protocol
565 sends passwords in plain text. If you can't afford the space for an
566 SSH daemon and you trust your network, you may say 'y' here. As a
567 more secure alternative, you should seriously consider installing the
568 very small Dropbear SSH daemon instead:
569 http://matt.ucc.asn.au/dropbear/dropbear.html
571 Note that for busybox telnetd to work you need several things:
572 First of all, your kernel needs:
576 Next, you need a /dev/pts directory on your root filesystem:
579 drwxr-xr-x 2 root root 0 Sep 23 13:21 /dev/pts/
581 Next you need the pseudo terminal master multiplexer /dev/ptmx:
584 crw-rw-rw- 1 root tty 5, 2 Sep 23 13:55 /dev/ptmx
586 Any /dev/ttyp[0-9]* files you may have can be removed.
587 Next, you need to mount the devpts filesystem on /dev/pts using:
589 mount -t devpts devpts /dev/pts
591 You need to be sure that Busybox has LOGIN and
592 FEATURE_SUID enabled. And finally, you should make
593 certain that Busybox has been installed setuid root:
595 chown root.root /bin/busybox
596 chmod 4755 /bin/busybox
598 with all that done, telnetd _should_ work....
