Other options are to start/stop programs in +/etc/ppp/ip-{up,down}.local, and to customize initscript dependencies +as described in: + http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=4 + + +Starting the Connection +======================= + +To start manually, with the modem connected: + /etc/init.d/net.ppp0 start + +To start automatically when the PC boots: + rc-update add net.ppp0 default + + +Kernel Configuration +==================== + +The ebuild, during an emerge, checks that the required kernel modules +are present. + +Note that in the list below, "[*]" means that the option is compiled +into the kernel, whereas "[M]" means that the option can either be +compiled into the kernel, or as a module. Compiling them into the +kernel is recommended, to guarantee that the modules are already loaded +when they are needed, and it will improve the bootup time by a couple +of seconds. + +In "make menuconfig", you can press "/" and search on e.g. "speedtouch" +to see exactly where an option is - the location of an option and its +dependencies can change between kernel versions. + +Check that the following kernel options are configured as shown (this +list includes the prerequisites, e.g. USB_SPEEDTOUCH depends on USB): + + Code maturity level options ---> + [*] Prompt for development and/or incomplete code/drivers + - CONFIG_EXPERIMENTAL + + General setup ---> + [*] Kernel Userspace Events - CONFIG_KOBJECT_UEVENT + (for kernels < 2.6.16 *ONLY*) + + Device Drivers ---> + Generic Driver Options ---> + [ ] Select only drivers that don't need compile-time external + firmware (*unselected*) - CONFIG_STANDALONE + [*] Hotplug firmware loading support - CONFIG_FW_LOADER + + Networking ---> + [*] Networking support - CONFIG_NET + Networking options ---> + [*] Packet socket - CONFIG_PACKET + [M] Asynchronous Transfer Mode (ATM) - CONFIG_ATM + [M] RFC1483/2684 Bridged protocols - CONFIG_ATM_BR2684 (only needed for PPPoE) + + Device Drivers ---> + Network device support ---> + [*] Network device support - CONFIG_NETDEVICES + [*] PPP (point-to-point protocol) support - CONFIG_PPP + [M] PPP Deflate compression - CONFIG_PPP_DEFLATE (only useful if + compression is supported - rare) + [M] PPP BSD-Compress compression - CONFIG_PPP_BSDCOMP (only useful + if compression is supported - rare) + [M] PPP over Ethernet - CONFIG_PPPOE (only needed for PPPoE) + [M] PPP over ATM - CONFIG_PPPOATM (only needed for PPPoATM) + USB support ---> + [*] Support for Host-side USB - CONFIG_USB + [*] USB device filesystem - CONFIG_USB_DEVICEFS + [M] (O or U)HCI HCD support + USB DSL modem support ---> + [M] USB DSL modem support - CONFIG_USB_ATM + [M] Speedtouch USB support - CONFIG_USB_SPEEDTOUCH + + + +Troubleshooting +=============== + +Try "emerge speedtouch-usb" again, because the ebuild checks that the +required kernel modules are present (showing a warning message if +appropriate), and creates the firmware files and symlinks in +/lib/firmware/ + +If the modem is unresponsive, then run "/etc/init.d/net.ppp0 stop" and +unplug the modem for 30 seconds, to drain its memory.

If there is no answer, then +file a bug at http://bugs.gentoo.org/ . + + +Compression +=========== + +Some ISPs require compression to be disabled in order for the +connection to work, so the default configuration described above +disables compression. Few ISPs support ADSL compression anyway. If you +are lucky enough to have an ISP which *does* support compression +(Google is your best friend for determining this), then compression can +be enabled by following these steps: + +* Compile the kernel modules CONFIG_PPP_DEFLATE and CONFIG_PPP_BSDCOMP +(only one is strictly necessary - pppd prefers "deflate" compression). +Add them to /etc/modules.autoload.d/kernel-2.6 or /etc/conf.d/net above +the "pppoatm" line, if they are not built-in. +* Remove the following options in pppd_ppp0: + noaccomp nobsdcomp noccp nodeflate nopcomp novj novjccomp +* Ensure that "debug" is in the pppd_ppp0 options, to check that +compression is being utilized. Note that "module registered" in +/var/log/messages only confirms that the kernel module is loaded - +it does not indicate that the connection is compressed. + + +Links +===== + +SpeedTouch ebuilds: https://packages.gentoo.org/packages/search?q=speedtouch +SpeedTouch hardware: http://www.speedtouch.com/support.htm +SpeedTouch firmware: http://www.speedtouch.com/driver_upgrade_lx_3.0.1.2.htm |
