11/20   PacHell (PacBell) now has this stupid PPPoE over DSL crap. Has
        anyone successfully gotten Linux or FreeBSD to run on this?
        URL would be nice.
            \_ no, the better question is, has anybody gotten their Macpoet
               garbage to work on their g3/g4 machines?!  I have had all
               the dsl stuff at home since last week but can't get
               the software to work;  everything is set exactly as they
               tell you in the the enclosed readme file.  Worse yet,
               the tech support is awful, and even if they could send
               someone out, I'm hard pressed for leave time.  The earthlink
               classic excuse was, "Uh...yeah, dsl service has been sporadic
               in the Bay Area...Just try logging in several days from now..."
        \_ redhat 7 comes with the roaring penguin pppOe package available
           as a service to install
        \_ We use Linux (RedHat 6.2) with RP-PPPoE (not w/ PacBell though):
                http://www.roaringpenguin.com/pppoe  -alanc-
        \_ What's the motivation for using PPPoE?
                \_ Access control - think DHCP with account name/passwd reqd.
                    (Easy to shut off if you don't pay your bill, just disable
                     account).
                   Also easier to throttle bandwidth down to the rate you're
                   paying for, so you don't complain when your higher than
                   average rates drop down to normal as more people sign up,
                   and easier to share infrastructure with other ISP's & keep
                   the billing straight.  (At least that's what the tech at
                   our ISP said off the record.)
           \_ but it is over DSL.  I thought the ISP can easily disconnect
              you at the central office.  BTW, doesn't PPPoE sound weird?
                        \_ Editing a file is much easier than sending someone
                            out to your neighborhood CO.
                Ethernet is designed to be a broadcast medium but PPP is
                point-to-point...
                    \_ well, whatever it is, it's a fucking piece of shit.

12/6    I'm running 64bit VMWare 2.0 in debian lenny/testing.  I have 18
        guest VMs running, all in bridged mode.  Works great.  the 19th VM
        I turn on has no working network.  No net, dhcp/tftp doesn't work,
        nothing.  Can anyone think of a network or kernel setting in Linux
        that would prevent any more VMs from getting network access?

10/15   Has anyone else used dnsmasq for DHCP and PXE booting?  Have you found
        a way to specify the 'next-server' option with dnsmasq?
        conventional DHCP daemons let me specify 'next-server', I can't
        figure out how to do it with dnsmasq.  Thanks - danh

        tests that need to get run on two separate sub-nets that now require
        me to physically go in and change the IP address of the test box.
        Cygwin is also installed if that helps any. Thanks

2/18    My DSL modem's ip address is 192.168.0.1, my internal network
        behind my router is 10.0.0.x. Is there a way I can configure
        the router so I can access the DSL modem from my 10.0.0.x
        network directly without re-wiring? Static routes? I tried it
        but no much luck. I also tried changing my internal network to
        192.168.0.x, but still does not work. Thanks.

1/28    Just switched to Comcast from SBC and generally happy with it.  But
        can someone please explain to me why they are constantly pumping
        ARP traffic through the network?  It seems harmless, but I'm curious
        as I didn't see it with DSL.  It's a little disconcerting to see
        constant traffic on your router, even if ARPs are harmless from
        a bandwidth perspective, and it makes the WAN send/receive light

1/21    I am trying to setup a small network for my girlfriend's
        mom's company.  They just bought an accounting package
        which requires windows 2003 server.  And they want internet
        access from each computer.  How should the network be setuped?
        Would it be dumb to use static IP for each computer and a
        computer as internet gateway?

8/29    What's the difference between a hub, a switch and a router?  Thx.
        \_ AFAIK, probably be corrected by someone:
           hub: Allows communication on a LAN with bandwith shared amongs all
                the nodes on the hub and maxing out at the max line speed.
           switch: Allows communication on a LAN with bandwith greater than
                the max line speed (point to point)

5/29    I'm sure there are people here using SBC DSL using linux
        I assume it is not too difficult to hack around their lame
        software and make it an "always on" connection.  Correct?
        Is it any easier/harder if I go with their wireless setup vs.
        the standard??  Info appreciated.

5/12    Hi, I run windows Xp home edition on my laptop.  It's hooked up
        to my DSL router via ethernet most of the time.  When I want to
        just use the laptop without a net connection, the laptop sometimes
        locks up and becomes really really slow.  To the point where I can't
        even right-click on the network icon to disable it temporarily.
        I can't even do Ctrl-Alt-Delete to bring up the task manager.

        it shows BIOS, but it won't show the WinXP screen.  So, it sounds like

Roaring Penguin has a free client for Linux, NetBSD and Solaris systems to connect to PPPoE service providers. Background and What's Included with rp-pppoe rp-pppoe now includes an optional GUI setup program. Note that the GUI is entirely optional and is meant for desktop users; Sniffer The PPPoE software includes a "sniffer" program which examines PPPoE connections from another computer and deduces any special options required by the Linux/BSD/Solaris pppoe program. If you wish to terminate many connections, you are urged to use the new kernel-mode PPPoE support. Relay Agent The PPPoE suite includes a PPPoE relay agent. The relay agent lets you run multiple PPPoE sessions from multiple machines behind a relay. The client, server and relay agent are user-mode programs and do not require any kernel modifications. They are fully compliant with 27 RFC 2516, the official PPPoE specification. You'll need to download the latest PPP daemon sources from CVS. Instructions for doing so are found in the docs/KERNEL-MODE-PPPOE file in the tar file. Kernel-mode PPPoE support is no longer considered experimental, but you'll need to install from the source gzipped tar file and read docs/KERNEL-MODE-PPPOE to use it. PPPoE Protocol Information If you want more information on PPPoE, you can look at some 28 slides (PDF format) from a presentation I gave, or a 29 paper (PDF format) I delivered at the Atlanta Linux Showcase. This gives an overview of the PPPoE protocol as well as the Roaring Penguin PPPoE client. If you want to study the client's source code, the slides and paper are a good place to start. Feel free to use and copy the slides, but please don't use them in a presentation without Roaring Penguin's permission. Before you download this software, check whether or not you really need it. If your ISP uses PPPoE, but has given you a router, you may not need a PPPoE client on your Linux box. However, if you have a DSL "modem" and your provider uses PPPoE, you need a PPPoE client. Download The software is available in a number of formats. For non-Red Hat distributions, we recommend rebuilding the RPM as detailed below. We'll repeat it because many people ignore the previous paragraph: The binary RPM's will not work on Mandrake, and probably won't work on non-Red Hat systems. Thanks to Declan Cooper for building the PowerPC RPM, and to Cynick Young for the Alpha RPM. Installation You have to be root to install the software. Tim Golden has kindly contributed pre-compiled versions of pppd and the associated kernel modules for Sparc Solaris; If those do not work, Guillermo Zarabozo has contributed a 41 package file for Sparc Solaris 8 which installs in /usr/local. I have had many reports of broken rp-pppoe packages in various Linux distributions. Specifically, Red Hat distributes a particularly butchered version of rp-pppoe which is very difficult to use without graphical tools. I don't mean to disparage Red Hat (I use it myself), but they really should not have modified rp-pppoe in the way they did. We regret that we cannot offer e-mail or telephone support for rp-pppoe. If you received rp-pppoe as part of a Linux distribution you paid for, you may have the right to support from the distribution vendor. Forum Thanks to the folks at 43 VoyForums, we now have a 44 forum for rp-pppoe.
