[pptp-server] flakey adsl

[George Vieira]

One thing that might help you a bit if your running Linux on both ends is
that if you can't fix the link problem itself then put into the
/etc/ppp/options.pptp file the following:

lcp-echo-failure 60
lcp-echo-interval 5

This will do continous pings to check that the link is up. If the link is
flakey and causes timeouts enough to trigger this, it'll drop the pppd link.

Then what you can do it in your /etc/ppp/ip-down.local file, detect the
`ipparam` setting you used and make it bring the link up. Though be careful
not to bring a link up when a current link is still active, I wrote scripts
to check this on mine and to wait until the old link fully completes...

This at least will help keep the link up and any telnet/ftp session may be
able to hang on longer.. worked for me anyway....

Hope this helps a bit...

Hi,

I have a remote site in New Zealand using pppoa (jetsream) to connect back
to my Melbourne Australia based host running a 2mb fibre link.  The host
side of the connection is rock solid, I can keep 100+ hour connections from
my home cable modem (melbourne based), but the pppoa seems to get heaps of
atm errors, these cause me no end of problems.  After a series of these atm
errors the vpn connection drops, does anyone know of a way to build some
more fail over protection into poptop.  I am using 1.1.2 version of poptop
with kernel 2.4.5 and full encryption.  I'm not looking for a magic bullet,
more so something that may help keep the connection up for longer than 15
odd minutes.

Any sughestions would be well received.

Thanks in advance.

Mick
