SOLVED Update error after upgrade

[northernsky]

Hello,

I upgraded to the latest version and ever since then I get this error: I have my DNS set but I am not sure what happened because it was working before I upgraded. It's probably not a bug but a pebkac error. Any help would be awesome!

Update server could not be reached
<urlopen error [Errno 51] Network is unreachable>

Ok so I have tried everything I know to fix this myself, but I'm really at a loss. I even completely reinstalled FreeNas and it's still a issue.... I would love some ideas from the vast community.

Thanks!

 

[dlavigne]

Were you able to resolve this?

 

[northernsky]

No I am still troubleshooting it. I am somewhat stumped.

 

[northernsky]

Did I post on the wrong place or maybe I did not explain my issue well enough for ppl to respond? I'm still not able to get this working.

 

[dlavigne]

Do you have a gateway and DNS set in Network -> Global Configuration. If not, does adding your default gateway and a DNS entry of 8.8.8.8 resolve the issue?

 

[northernsky]

I tried that initially after searching this site for that error that I got and it did not fix it.

 

[dlavigne]

Are you behind a proxy or a firewall?

 

[northernsky]

Not behind either.. as it stands nothing should be preventing the update to get out and I'm still not sure what to do as far as troubleshooting goes.

 

[dlavigne]

Something in your networking is preventing it from going outside the network. At this point, running a tcpdump or some other packet sniffer might help to figure out the issue.

 

[northernsky]

Right I know it's something locally on the FreeNas server but I am not sure what and I have never run a packet sniffer on a nix server so i'll have to go figure that out. I wish I had never moved upgrade chains. Irritating.

 

[dlavigne]

You should be able to reboot into your previous boot env (before the upgrade). However, if there is an issue in your network that might not make a difference.

 

[northernsky]

I know longer have that environment because after the upgrade and I started having this issue I decided to start over and I did a fresh install of Freenas using the latest 11.2 - the problem followed the install. So after the initial upgrade something might have changed in my nic card?

 

[dlavigne]

What is the full output of:

1. ifconfig
2. more /etc/resolv.conf
3. netstat -rn

 

[northernsky]

What is the full output of:

1. ifconfig
2. more /etc/resolv.conf
3. netstat -rn

Sorry it took so long to reply but here are the results of the syntax - see attached.

 

[dlavigne]

Double-check your default gateway settings. The lack of a G flag in netstat -rn means there's no gateway.

 

[northernsky]

Thanks dlavigne for all your help. For whatever reason it was missing the gateway but I am not sure why it never made it into the settings after install (and the initial upgrade for that matter).

Again, thanks!

Scott
