[plug] Short connect time problem.

[Bill Kenworthy]

I have been looking at my connect times in the log because of the
problems I am having and would like some comments on the following (I
have sent this to iinet and want to make sure I have no problem at my
end that could cause this - particularly whether any pppd or linux
setting could possibly cause this.  Other than security upgrades, no
changes were made to the box at the time all this started):

1) EVERY time I try and connect, the first time appears to negotiate a
connection, transfer a few packets of data and then disconnects.  This
always occurs since this started.  I know of no mechanism where line
interferance can cause the first connect to always fail, but the next to
(usually) work.

2) The disconnects for connections that hold (as shown below - note that
this shows all connect times for completeness and has not been edited.)
range from about 77-87 minutes with a few grouped at 81 minutes.  This
fact seems a bit suspicious and would appear to rule out line
interference as it is timed from when the connection is made.

The line shows what iinet consider a poor s/n (38db) and I have a molds
test booked, but the timings below seem a bit sus!
