GENERAL +---------- + +This package is used to estabilish basic connection to the +Internet via DSL/ADSL modems. This is also known as the +PPPoE or PPP-over-Ethernet connection. + +The PPPOECD program included in the OpenWrt distribution is a +modified version of the PPPOECD that is present in the original +Linksys firmware. + +This modified version is directly supported by the OpenWrt +startup scripts. + +2. BUILDING +----------- + +If you have a pre-compiled PPPOECD package, skip this section. + +PPPOECD can be built in two ways. As an integrated part +of the OpenWrt FLASH image or as an .ipk package that can +be installed separately. + +To build PPPOECD as an embedded component, add "pppoecd" to the +TARGETS variable in the main OpenWrt Makefile before the +"openwrt-bin" value. + +To build as a standalone package, add "pppoecd" to the +PACKAGES variable in the main OpenWrt Makefile. + +3. NVRAM variables +------------------ + +In order for the PPPoE link to be established by the networking +scripts the following NVRAM variables must be present: + +wan_ifname Should be set to: ppp0 + +wan_proto Should be set to: pppoe + +pppoe_ifname Set it to the WAN interface on which the PPPoE + is to function. On a 2.0 or a GS model it is + usually vlan1. The 1.0 and 1.1 models used vlan2. + +ppp_username User name for your PPPoE connection. + +ppp_passwd Password for the connection. + +ppp_redialperiod Time between reconnect attempts. + Usualy set to 30. + +ppp_idletime Time the link has to stay dead before reconnecting. + Usually set to 5. + +wan_mtu The Maxumum Transfer Unit for the PPPoE connection. + Typically 1492. + +Please consult the OpenWrt WIKI or the forum for more +information on NVRAM variables. + + +4. STARTUP / SHUTDOWN +--------------------- + +OpenWrt will attempt to connect using PPPOECD when starting up. +The script responsible for that is /etc/init.d/S40network. + +You can also manually start the PPPOECD by doing: + + . /etc/functions.sh; ifup wan + +Similarly you can shutdown the PPPOECD by doing: + + . /etc/functions.sh; ifdown wan + + +5. CONFIGURATION +---------------- + +PPPoE firewall configuration is the standard OpenWrt configuration +in /etc/init.d/S45firewall that applies to all the other types +of connections to the Internet. + +Additional actions can be performed when connecting or disconnecting +by modifying "ip-up" and "ip-down" scripts in the /etc/ppp directory. + +When connecting, PPPOECD creates /tmp/resolv.conf file that contains +DNS server entries as supplied by the ISP. The standard ip-up +script will also add a default route leading via the PPPoE link. + +6. DIFFERENCES FROM THE ORIGINAL PPPOECD +---------------------------------------- + +The main difference is the location of files. Original Linksys +PPPOECD operated almost exclusively in the /tmp/ppp directory. This +however prevents any persistent configuration of the program via +ip-up or ip-down scripts. Also the program itself was located in +/usr/sbin whereas OpenWrt scripts expect it to be in /sbin directory. + + diff --git a/obsolete-buildroot/make/pppoecd.mk b/obsolete-buildroot/make/pppoecd.mk new file mode 100644 index 000000000..48ebbb8a3 --- /dev/null +++ b/obsolete-buildroot/make/pppoecd.mk @@ -0,0 +1,73 @@ +# build the Linksys pppoecd + +# Note that this patches the linksys pppd before patching pppoecd. +# The pppd patch changes the pathnames that pppoecd will use. +# In an attempt to avoid conflicts the marker file is called +# .patched-pppoecd in the pppd directory. + +PPPD_DIR=$(BUILD_DIR)/WRT54GS/release/src/router/ppp/pppd +PPPD_PATCH=$(SOURCE_DIR)/pppoecd-pathnames.patch + +PPPOECD_DIR=$(BUILD_DIR)/WRT54GS/release/src/router/ppp/pppoecd +PPPOECD_PATCH=$(SOURCE_DIR)/pppoecd.patch +PPPOECD_BIN=$(TARGET_DIR)/sbin/pppoecd + +PPPOECD_IPK_DIR=$(BUILD_DIR)/pppoecd-1.0 +PPPOECD_PACKAGE=$(BUILD_DIR)/pppoecd_1.0_mipsel.ipk +PPPOECD_IPK_BIN=$(PPPOECD_IPK_DIR)/sbin/pppoecd + +# patch pppd for the openwrt compatible path names +$(PPPD_DIR)/.patched-pppoecd: $(BUILD_DIR)/WRT54GS/.source + cat $(PPPD_PATCH) | patch -d $(PPPD_DIR) + touch $(PPPD_DIR)/.patched-pppoecd + +# patch the pppoecd itself for GCC3.x compatibility and to move pppoecd to /sbin +$(PPPOECD_DIR)/.patched: $(PPPD_DIR)/.patched-pppoecd + cat $(PPPOECD_PATCH) | patch -d $(PPPOECD_DIR) + touch $(PPPOECD_DIR)/.patched + +# build the pppoecd binary for the ipk version +$(PPPOECD_IPK_BIN): $(PPPOECD_DIR)/.patched + mkdir -p $(PPPOECD_IPK_DIR)/etc/ppp + cp $(SOURCE_DIR)/pppoecd.ip-up $(PPPOECD_IPK_DIR)/etc/ppp/ip-up + chmod a+x $(PPPOECD_IPK_DIR)/etc/ppp/ip-up + $(MAKE) -C $(PPPOECD_DIR) CC=$(TARGET_CC) LD=$(TARGET_CROSS)ld \ + SRCBASE=$(OPENWRT_SRCBASE) INSTALLDIR=$(PPPOECD_IPK_DIR) LIBDIR=$(UCLIBC_DIR)/lib \ + STRIP="$(STRIP)" \ + install + +# setup ipkg control files +$(PPPOECD_IPK_DIR)/CONTROL/control: + mkdir -p $(PPPOECD_IPK_DIR)/CONTROL + cp $(SOURCE_DIR)/pppoecd.prerm $(PPPOECD_IPK_DIR)/CONTROL/prerm + chmod a+x $(PPPOECD_IPK_DIR)/CONTROL/prerm + cp $(SOURCE_DIR)/pppoecd.postrm $(PPPOECD_IPK_DIR)/CONTROL/postrm + chmod a+x $(PPPOECD_IPK_DIR)/CONTROL/postrm + cp $(SOURCE_DIR)/pppoecd.conffiles $(PPPOECD_IPK_DIR)/CONTROL/conffiles + cp $(SOURCE_DIR)/pppoecd.control $(PPPOECD_IPK_DIR)/CONTROL/control + +# build the ipk package +$(PPPOECD_PACKAGE): $(PPPOECD_IPK_BIN) $(PPPOECD_IPK_DIR)/CONTROL/control + cd $(BUILD_DIR);
