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 <asyncmap 0x0> <auth chap MD5> <magic
0x24d2bb93> <pcomp> <accomp>]
rcvd [LCP ConfRej id=0x1 <auth chap MD5>]
sent [LCP ConfReq id=0x2 <asyncmap 0x0> <magic 0x24d2bb93> <pcomp>

rcvd [LCP ConfReq id=0x2 <mru 1500> <asyncmap 0x0> <magic 0x9f3b8e8b>
<pcomp> <accomp>]
sent [LCP ConfAck id=0x2 <mru 1500> <asyncmap 0x0> <magic 0x9f3b8e8b>
<pcomp> <accomp>]
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?

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)
