What's the recommended way to deploy PPP/PPPoE in 20.04 ? Netplan doesn't seem to support that; Is ifupdown still the way forward even though it's going away ?
Cheers,
when i connect the ppp, the network connection is ok.
but after n minuter, the connection will disconect random.

I'm trying to create ppp0 interface. I have written in /etc/network/interfaces:
auto ppp0
iface ppp0 inet ppp
provider international
But when I try "sudo ifconfig ppp0 up" I get:
ppp0: ERROR while getting interface flags: No such device
I have restarted my PC and network manager. I have never used ppp interfaces so I'm probably missing some previous basic configuration. How can I set up a ppp0 device?
I am a new ubuntu user and connect to the internet using wi-fi broadband on my notebook. But I need to setup a dial-up connection through my phone which can keep me online while I travel.
I have tried connecting to dial-up using pppconfig, wvdial and gnome-ppp. I do not know whether they use the same files for connecting but I have only been able to connect using Gnome-ppp. But the connection is intermittent and disconnects every five seconds or so. The exit code is 16 which I checked in man and got to know that the modem hangs itself up.
I am connecting my phone to ubuntu as a usb modem. And as I am new I might have skipped a step or two.
Please suggest a solution or an alternative to this. I have put down the Gnome-ppp log.
Thanks.

I have multiple 3G USB based Modems. I would like them to keep connected simultaneously, NOT necessarily aggregating their bandwidth; a separate intelligent application would manage their utilization effectively.
However I am running into problem of setting up proper routes for the ppp0,ppp1 interfaces: when one of them connects, other's entries in the routing table get updated so it is no more usable. If I reconnect the second one, it would override the first one's routing entries. If I do it over and over, sometimes both of them's entries disappear while in rare cases the two work well.
I have tried it both using NetworkManager as well as WVDial but issue pops up in both of these. Perhaps both of them use same PPP dialer at the backend and thats why this issue appears.
What is the proper solution to make them work together? In the long run, I'd also like them to automatically dial in once USB gets connected.
