[Voyage-linux] bring up ppp automaticaly during boot

[Robert Rawlins - Think Blue]

Hey Beat, and everyone else!

Thanks a great deal for all your suggestions! I've built a couple of systems
working on different approaches which I can now test and see which does the
best job for me J I'll keep you all up to date on things and the final
descision that we make.

Rob

You can tell pppd to try endless to reconect if ppp line goes down i.e. pppd
will reconnect.
address and netmask is in case you have fix ip. I have dynamic ip but
configured so...
My system is configured as follows:

My provider script is /etc/ppp/peers/telecom

/etc/network/interface entry:

auto telecom
iface telecom inet ppp
        provider telecom
        address 200.200.200.123
        netmask 255.255.255.0
# please do not modify the following line
        pre-up /sbin/ifconfig eth1 up # line maintained by pppoeconf
        up /etc/network/telecom_config_interface || true

The script
/etc/network/telecom_config_interface
will enable masquerading and port forwarding stuff etc.

Add the following options to the file /etc/ppp/peers/telecom:
  persist
  maxfail 0
To try endless with the modem to connect (mz provider use pppoe).

Greetings

Beat

Hello Guys,

 

There seem to be a lot of network related questions on the list recently,
thought I'd add another one ;-)

 

I've got a ppp script configured on the system which connects just fine with
'pon' and likewise disconnects with 'poff'. I'm now looking to have the
system treat it like the Ethernet, bringing ppp0 up when the system boots
and then maintain that connection if it is dropped.

 

What would you suggest is the best way to go about this? I've added the ppp0
as an interface to /etc/network/interfaces like so:

 

auto ppp0

iface ppp0 inet ppp

  provider three

 

with 'three' being the name of the ppp dialer that I'm looking to use.
However when I run 'ifconfig ppp0 up' I simply get an error message which
says: 'ppp0: ERROR while getting interface flags: No such device' and if I
restart networking I get an error like so:

 

voyage:~# /etc/init.d/networking restart

Reconfiguring network interfaces...if-up.d/mountnfs[eth0]: waiting for
interface ppp0 before doing NFS mounts (warning).

/lib/udev/hotplug.functions: line 10: [: : integer expression expected

/lib/udev/hotplug.functions: line 10: [: : integer expression expected

done.

 

I'd appreciate your thoughts guys, let me know how you would go about doing
this, like I say, I want to bring the connection up as early as possible in
the boot and then ensure it is maintained and reconnected if dropped.

 

Also, getting the system to do a timesync once connection is made would also
be good so the system has the latest time, in the same was it does when
connecting over Ethernet.

 

Cheers,

 

Rob
