[LARTC] ADSL with PPP failover

[Daniel Horth]

Hi - I've been looking around for simple answers to this for a while now,
but haven't been able to find any HOW-TO type documentation. I am
administering a site with a remote location connected primarily via a cipe
tunnel over a SHDSL connection. We also have a direct PSTN connection
between the sites. Seeing as phone calls here are not timed I plan to keep
the PSTN connection alive even when the cipe tunel is active. I am looking
for information as to the best way to set up this network, so that if the
cipe connection goes down all traffic is automatically routed over the ppp
connection, and when the cipe connection comes back up the traffic is once
again routed via the cipe connection.

We currently only have one remote location to worry about, but may soon be
expanding to multiple sites, with multiple links.

I originally thought that I'd be setting this up using weighting in the
routing table, but now believe that methodology is out of date even if it
would work - more recently I have been thinking that this sort of failover
setup would best be implemented using RIP (or is that out of date too?). I
was hoping that someone could tell me if I was headed in the right direction
before I set out reconfiguring the routing on all our servers. I'd also be
grateful for any pointers towards relevant reading or HOW-TOs that relate.

Using Linux 2.4 (Redhat 9)

Thanks in advance!

- Dan.

[LARTC] newbie - shaping a PSTN connection

[Daniel Horth]

Hi - I've been going through the LARTC how-to and have successfully used the
sample scripts (and wondershaper) with my xDSL links.

I'm now faced with the challenge of providing 8 users at work an effective
remote access connection over a PSTN ppp connection. The critical traffic in
this case relates to our stock enquiry application which is running over
terminal services.

I've been attempting to use the wondershaper script with this PSTN
connection - but don't seem to be able to improve latency at all. doing a
bit of research I've only really found references to shaping broadband
connections. Surely shaping of PSTN ppp connections is equally (probably
more) applicable?

I was hoping that someone might be able to point me in the direction of
information relating to successfully providing my users high priority
terminal services traffic over the PSTN link.

I would also appreciate being shown where I might find a searchable archive
of this list.

Thanks in advance!

- Dan.

PS. in case you think I'm mad running 8 users over PSTN - it's just a
stop-gap while we wait for our SHDSL installations - which should be in by
the end of the month. In future I will be using the PSTN as a backup incase
the SHDSL goes down though - so any shaping work will not be lost!
