Thread: problem with authentication

  1. problem with authentication

    We try to establish a dialin connection from an old Linux box (SuSE 6.x)
    to an new one (SuSE 10.1). We try to authenticate with CHAP. Here's the
    log:

    pppd 2.4.3 started by root, uid 0
    using channel 7
    Using interface ppp0
    Connect: ppp0 <--> /dev/ttyS0
    sent [LCP ConfReq id=0x1 0x24d2bb93> ]
    rcvd [LCP ConfRej id=0x1 ]
    sent [LCP ConfReq id=0x2
    ] rcvd [LCP ConfAck id=0x2
    ] sent [LCP ConfReq id=0x2 0x24d2bb93> ] rcvd [LCP ConfAck id=0x2
    ] rcvd [LCP ConfReq id=0x1 1500> ]
    No auth is possible
    sent [LCP ConfRej id=0x1 ]
    rcvd [LCP ConfReq id=0x2
    ]
    sent [LCP ConfAck id=0x2
    ]
    sent [LCP EchoReq id=0x0 magic=0x24d2bb93]
    peer refused to authenticate: terminating link
    sent [LCP TermReq id=0x3 "peer refused to authenticate"]
    rcvd [LCP TermReq id=0x3]
    sent [LCP TermAck id=0x3]
    rcvd [LCP TermAck id=0x3]
    Connection terminated.

    What's wrong?

    Regards,

    You are requiring the peer to authenticate itself to pppd, which you
    likely don't want to do. Add the "noauth" option and, if present,
    drop "require-chap."

    Irreconcilable differences.

    a) when you post please make sure taht the formatting of the lines makes
    the lines readable.

    b) You asked teh remote side to authenticate themselves to you . They
    refused. End of story.
    Why are you asking the remote side to authenticate themselves to you? If
    they are an ISP they will never do so.
    (remove the require-chap or +chap option)
