[RP-PPPoE] Getting disconnects - but reconnecting ok only seconds later

[Paul Young]

Hello everyone,

First let me say I am new to rp-pppoe so I am open to all advice.

We have been experiencing a drop out with our internet connection and
I am not sure what the cause is.

I have raised this with our service provider and they believe it is on our side.

A little background - we are running a Centos 6.5 Server as our
internet gateway\router. It is using rp-pppoe-3.10-10.el6.x86_64 to
sign into the Service provider.

The service provider has a fibre cable running into our rack and then
into an NTU with an ethernet sign off that is connected to the outside
facing nic on the gateway server.

And I get things like this in the log (some details edited):

Apr  9 08:13:31 <my server> pppd[5244]: No response to 6 echo-requests

internet facing address>
Apr  9 08:13:45 <my server> pppd[18364]: remote IP address <My
Providers upstream address>

To me it looks like something on our service provider side from
reading through the above. However I get the impression from them that
they think the router has an issue.

But they only appear to check after the fact.

What am I missing here?

Thanks
