After 4 months of successful usage my TonidoPlug2 just isn't working anymore. It constantly flashes purple light on status and there's no network connectivity after trying several different known good network cables. There's also no wireless signal detected. I've tried the dhcpnet.sh procedure without success. Any other things I can try . . . or am I looking at a RMA exchange???

Try this link and see if you can collect logs:

Thanks for the assistance. I've attached the "debug" results to this post.

Looks like you have a external harddisk connected to the plug (either via SATA interface or USB).
Not sure if you are booting with that, but I see I/O errors in the logs and tonido is not able run. If you did boot with the disk then you cannot SSH into the plug as well. Try with a different disk.

I've plugged in another harddisk (this one's FAT32, the others were ext3) without the network cable plugged in, and the status light went solid blue. I then plugged in the network cable and the status light started flashing purple again . . . no network connectivity (lan or wireless) . . . from either my router nor a netbook plugged to the other end of cable (and requesting DHCP from the Tonidoplug). I suspect there may be issues with the network adapter on the Tonidoplug. Any other suggestion for diagnosis?? Thanks!

Looking at your logs again, looks like your internal flash is full as well.
This happens when files get written to the flash instead of USB.


Power off the plug. Try to remove the HDD. Power it on again. (with network connected)
See if you can get a DHCP address to the plug.
Once you get a DHCP address then we can SSH into the plug and cleanit up.
If you still don't get DHCP address, send a mail to support@codelathe.com referring to this thread.
