[ANSS-netops] help with basalt, pls?

[Merritt, Jonah]

Hello everybody,

We are seeing the same issues! Jacob is correct...if you reboot the Basalt
(or Granite) it loses contact with the gateway. This issue seems to have
manifested itself more is subsequent Linux updates (we are running 2.6
update 6). We also almost exclusively use Raven XE or GX440 modems.

What I have found that all is well after performing the "netconfig" script
and setting up NetWatcher. However, once you reboot you loose all remote
connectivity. If you get into the Basalt locally via SSH and restart
networking (/etc/init.d/networking restart) all is well again....until the
datalogger reboots again.

It should be noted that if you are able to log into the Raven, you can
successfully ping the Basalt.

I have contacted KMI about this and it was suggested that the problem
resides with the modem and not the digitizer. I'm not convinced that it's a
Raven issue as we have used these for several years without any significant
issues. It was also suggested that the NetWatcher ping address be something
else besides the gateway address....say 8.8.8.8. I did this without any
resolution.

We will be experimenting with this over the coming weeks, but I suspect
that it is an issue with the digitizer itself. I'll keep the group posted.
