    Hello

    on my dsl-connection my connections gets dropped after 5 to 25 minutes.
    (Sometimes faster, if I e.g. start mldonkey-overnet)

    I use the pppoe plugin with pppd 2.4.3
    What I found strange ist, that my connection had an IPCP id=0x0 message
    exchange at the beginning:
    43:08 [27444] rcvd [IPCP ConfReq id=0x0 ]
    43:08 [27444] sent [IPCP ConfAck id=0x0 ]
    and dropps the connection with:
    47:13 [27482] rcvd [IPCP TermReq id=0x0]

    After that pppd can't establish another connection, unless I replug the
    ethernet!-cable between my computer and the modem.

    I have already contacted my ISP, but it's now the 3rd day (my first 3 days
    with dsl) where they "try" to find out what could be wrong. ("Do you use
    the supplied telephone-cable",...)
    (Just to be clear: i have had problems since the first time I connected.)


    So my questions are:
    *) Do you think, this could be my systems fault, i.e. linux not capable of
    handling the connection? Or should I try to get for instance another
    modem?

    *) Where would you start "debugging"?

    Here is what I've tried already:
    * used 2 different network-cards
    * 2 different (Linux) systems (gentoo and kubuntu-live-cd) (did not look at
    kubuntus pppd version though ):
    * 2 different ethernet cables
    my ISP verified? my line and stated that everything looks correct.

    My system:
    AMD64, Gentoo, 2.6.16-ck11, pppd 2.4.3, currently nforce 1Gb ethernet
    Modem:
    Zyxel prestige 645 (600 series)

    thanks for trying
    christian

    I think it's more likely that you need to find a better ISP.

    I don't think the version of Linux or the Ethernet cable would be at
    fault here.

    That's a little suspicious. If you don't have multiple PPP links
    intentionally configured, it looks like you might have multiple
    instances of pppd running.

    Plus, that message is printed _only_ when you use the obscure "unit 0"
    option. Why are you doing that?

    > 47:13 [27482] rcvd [IPCP TermReq id=0x0]


    Up to this point, I didn't see anything wrong with the PPP
    negotiation. Everything looks fine, so the problem is on the peer's
    side.

    This is more suspicious stuff. It looks like you did indeed have two
    unexpected instances of pppd running at the same time.

    I don't think you want to do that. It might have something to do with
    the fact that your connections are dropping.

    I apparently started 2 pppd sessions while debugging..
    Wasn't the reason for my problem though.

    Apparently gentoo uses the unit option in their init.d script. I've never
    seen it before.

    I had the opportunity to borrow a dsl modem from my uncle --> worked.
    After some unnecessary discussions with my ISP they sent me another modem.

    My connection works perfectly now.
