Topic: pppoe / pppd terminates unexpectedly

[pwalter]

All,

server: SME 6.01 upgraded with smeplus script

I have an intermittent problem with my pppoe adsl connection. After a few hours, the internet connection dies. The server log contains the following entries:

Using ifconfig, eth1 (external network card interface) appears normal, but the ppp0 interface has disappeared! The only way to fix this seems to be to restart the server, at which point everything operates normally.

Can anyone shed light on what is happening here, what diagnostics I can use, or how to fix this?

Yeah, that'd be right. The pppd program terminated because the remote side stopped talking to it. A new pppoe/pppd will start up, but in the meantime there is no ppp0 device.

I guess there is a bug in your NIC or NIC driver. Comms to the DSL modem fails, and a reboot fixes it. Only thing I'd suggest to try is to remove and reload the NIC driver - but you'd only be able to do that while it wasn't in use.

Charlie,

Thanks for responding. I fixed it - sort of; I wiped the machine and spent all night reloading SME 6.01. The problem has not recurred, so I suspect that something was corrupted somewhere - perhaps the NIC driver, although I am using the same one now! One notable difference I noticed is that, before, the "ethernet active" light on the NIC and on the ADSL modem would only come on after pppd was started on bootup - now it comes on more or less immediately as SME boots, so maybe there were problems loading the NIC driver.
