This directory contains most of the network applications contained
under the uIP-1.0 apps directory. As the uIP apps/README says,
these applications "are not all heavily tested." These uIP apps
include:
dhcpc - Dynamic Host Configuration Protocol (DHCP) client
resolv - uIP DNS resolver
smtp - Simple Mail Transfer Protocol (SMTP) client
webclient - HTTP web client
webserver - HTTP web server
You may find additional information on these apps in the uIP forum
accessible through: http://www.sics.se/~adam/uip/index.php/Main_Page
Additional applications that were not part of uIP (but which are
highly influenced by uIP) include:
dhcpd - Dynamic Host Configuration Protocol (DHCP) server
tftpc - TFTP client
telnetd - TELNET server. This is the Telnet logic adapted from
uIP and generalized for use as the front end to any
shell. The telnet daemon creates sessions that are
"wrapped" as character devices and mapped to stdin,
stdout, and stderr. Now the telnet session can be
inherited by spawned tasks.
ftpc - FTP client
thttpd - This is a port of Jef Poskanzer's THTTPD HTPPD server.
See http://acme.com/software/thttpd/.
If you use DHCPC/D, then some special configuration network options are
required. These include:
CONFIG_NET=y Of course
CONFIG_NSOCKET_DESCRIPTORS And, of course, you must allocate some
socket descriptors.
CONFIG_NET_UDP=y UDP support is required for DHCP
(as well as various other UDP-related
configuration settings).
CONFIG_NET_BROADCAST=y UDP broadcast support is needed.
CONFIG_NET_BUFSIZE=650 The client must be prepared to receive
(or larger) DHCP messages of up to 576 bytes (excluding
Ethernet, IP, or UDP headers and FCS).
