Network Space Unreachable

Post by rimoth » Tue Nov 13, 2012 2:51 pm

Hi,

I am having difficulty trouble shooting an issue where my NS2 is no longer visible on the network.

I have installed andreus' custom capsule (thanks), and also have a debian chroot (squeeze) which runs logitech media server.

Every week or so the NS2 is no longer visible on the network. I cannot ping the box. When I press the power button the disk spins up but I still can't ping the box. If I then press and hold the power the unit will power down and then I can restart the box and it will be fine for a few days or even 2-3 weeks.

I know that the router the ns2 is connected to occasionally crashes and reboots. Could this cause the ns2 to lose its network connection and no longer be available on the network?

Are there any logs on the ns2, in the native OS and/or the chroot environment which I can check to see what is happening to cause the ns2 to be no longer available. Everything else is working great, it is just a pain having to reboot it occasionally.

Thanks in advance...Tim

Any ideas on what I can check to identify the reason for no longer being available on the network.

Does the NS2 auto negotiate a new ip address if it disconnected and reconnected to the LAN?

Any pointers would be appreciated. Thanks

I don't know if the ns2 does it witht he lacie firmware.
Your dhcp server decides how long the lease period will be for the ip address. if this a router then often you can set it to not expire or so,then there will be no renew necessary. You should also be able to see if the the lease expired or not in the router.

Thanks. I will check the lease period. I also did a general search on linux logs and system crashes so I have a little to be looking at for the moment. Will post back when I find out more.

I checked the router configuration and assigned the NS2 to be a Network Storage device which allowed a static ip configuration with no lease period.

Unfortunately this made no difference!

I experienced a loss of the NS2 this afternoon and looking in /var/log/messages I saw the following. From what I can tell it took a couple of attempts but managed to reconnect to the network.

Can anyone take a look and see if there is something which might point to a problem. Thanks.
