HELP: PPPd Serial-loopback error message

HELP: PPPd Serial-loopback error message

Post by S. Setvi » Sun, 01 Dec 1996 04:00:00

Hello. I am trying to set up ppp on my linux box.

I had pppd and chat working, but my logon script wasn't, so I changed
/etc/resolv.conf and /etc/hosts, and now pppd doesn't even get so far as
to start chat. It exits even before it reaches to the chat command.

Here is the message I get from pppd:

Dec  1 01:13:49 ender pppd[181]: pppd 2.2.0 started by root, uid 0
Dec  1 01:13:51 ender pppd[181]: Serial connection established.
Dec  1 01:13:52 ender pppd[181]: Using interface ppp0
Dec  1 01:13:52 ender pppd[181]: Connect: ppp0 <--> /dev/ttyS2
Dec  1 01:13:52 ender pppd[181]: Serial line is looped back.
Dec  1 01:13:52 ender pppd[181]: Connection terminated.
Dec  1 01:13:52 ender pppd[181]: Exit.

As you can see it says serial line is looped back. whatever that means.

If someone could help out I'd really appreciate it?

P.S. before it was able to startup chat, dial the modem, look for prompts,
etc... (I realize now I had it looking for the wrong prompts, but now I've
got a bigger problem). Now it won't even start chat and dial the modem. It
apparently fails when I tell pppd to look for /dev/ttys2 or /dev/modem or

Thanks for any help,



1. pppd dies -- serial loopback

Ever since upgrading to Mandrake 7.1, kppp seems
to be flaky.

Almost every other time I dial out to connect to
my ISP, the ppp daemon dies giving me the
following error:

Sep  4 11:25:35 Apollo pppd[1331]: pppd 2.3.11
started by hiten, uid 501
Sep  4 11:25:35 Apollo pppd[1331]: Using interface
Sep  4 11:25:35 Apollo pppd[1331]: Connect: ppp0
<--> /dev/ttyS2
Sep  4 11:25:38 Apollo pppd[1331]: Serial line is
looped back.
Sep  4 11:25:38 Apollo pppd[1331]: Connection
Sep  4 11:25:38 Apollo pppd[1331]: Exit.

The connection does go through atleast 1 out of 3
tries;  This trouble began after I upgraded from
Mandrake 7.0 to 7.1

I am at a complete loss as to what is going on

Any help is appreciated.
