[6.8.0] NO INTERNET; UNABLE TO CONNECT to GITHUB etc

[djhunter67]

I have been unable to update since 6.6.7 of which I have to rollback to after every update since 6.6.7.  I have tried to reset my network setting back to default as much as I could.  I have dual NIC's on the motherboard, a 10 Gbps fiber NIC, and a quad 1 Gbps card installed.  only the dual and the 10 Gbps are connected to anything.  Please help.

 

I consistently have no internet connectivity of my server after 6.6.7.

Hi there,

 

From looking at your logs, all the network devices in the system are loading their appropriate drivers.  What I would try doing is removing the add-on PCI cards and just booting off the dual on-board NICs.  If that works, add the 10gbps card and see if that works.  If so, add the quad port back and see what happens.  In addition, maybe @bonienl can take a look at your diags as he is our resident networking expert (and hopefully susceptible to flattery ;-).

I'm on it. Be back soon.

No joy. None of those cards removed improved my situation.  Still have no connectivity not to mention my dockers are all out of whack.

Can you give us some more details about your hardware / environment?  What kind of router/switch are you using?  Firewall?  What about the actual server itself?  A breakdown would be helpful.

One other thing to try would be to make a backup of your flash, then reformat and install Unraid fresh on it to see if a clean boot (no previous settings) works ok or not.  If so, you can restore from backup, but know that something in the configuration is to blame.  The tricky part here is that without a replica of your setup, it can be very difficult for us to diagnose and resolve your problem.  We're going to have to rely on a bit of trial and error experimenting to figure out where the issue really lies.

 

Edit:  You could also try just deleting the network.cfg and network-rules.cfg file after making a backup.

Ok, I have just finished swapping out the Motherboard, RAM, and CPU for known good ones (Was going to do that anyways) and I still have the same issue.  Now, I have just seen your suggestions, I'm going to delete the network config files and then reboot.  I have a backup of the flash drive that I have had to use twice now since I buggered up the manual rollback a couple of times.

 

Thank you so much for the assistance.

Can you screenshot your routes listed in Settings->Network Settings->Bottom of the page? Before and after the upgrade.

 

Is your 10Gbps NIC configured correctly? The gateway isn't in the same subnet as the interface which usually isn't intentional. 

 

In your syslog I see:

Dec 16 19:58:50 Tower rc.inet1: ip -4 route add default via 192.168.1.1 dev eth2 metric 210

 

which looks like it is making the default route via your 10Gbps NIC.

I made the main the 10Gbps on purpose. I am presently trying to find how to connect to the server after I just deleted the two network files and rebooted.  I presently have the server terminal on a seperate monitor and the flash drive plugged into my main PC looking for an IPaddress.  http://tower is not working and I am not seeing...... oh..... the 10Gbps is preventing my server from getting to the internet since that card is only locally connected... OK...

 

I am still just trying to find or set an ip address right now. Please help with this part?

Default network configuration (after deleting config/network.cfg) is to use DHCP so it should get IP from router. Are you sure you don't have a hardware (cable, port, etc) issue?

Everything worked perfectly fine in Unraid 6.6.7. Any update after that eff's up the server to internet connection.  I deleted the files but the network.cfg file was never created again.  What do I do? I am so at a losss. I'm willing to reinstall the entire Unraid again.... If i do that though, how do I retain the array's data?

Sorry had to go out for a little bit.

 

I know this is stressful but we should be able to get things figured out. 

 

When you're at the 6.8.0 console can you run "ip link show" and give the output? I have a suspicion that your 10Gbps NIC is in a down state and not coming up for some reason. It will also show the state of all other NICs on the system.

 

One thing you can try is to create a brand new 6.8.0 flash drive and boot from it. This should show us if there are any incompatibilities between your system and the new version.

I literally just finished using the USB Flash Creator. It finished less than 30 seconds ago. I'm about to put it in and boot up. I took a picture of the array and have a complete backup of the flash drive. Here goes!

Another thing you *could* try since your install seems to insist that eth2 have the default route assigned to it. In your network-rules.cfg you could change the gigabit interface(MAC d0:50:99:83:8b:80) to be eth2 instead of eth0 or something else.

I have been working on this non-stop since we've started chatting this evening.  I finally fixed it...

 

The Fix:

 

Downloading USB Creation Tool, fresh install to UNRAID USB, and copy over plugins, docker, and disk config information only from flash drive backup.  Left DHCP on and used the initial IP assigned.  Changed the IP back to what it was before and all is still good.

Glad you have it working! I still wonder why the existing configuration would not work when upgrading...

[jonp]

Same.  Very confused on what happened here.  Wish we knew.  At this point though, I'm just glad you got it sorted out!

It was because the docker, under settings, would not let me set the router ip address for an internet connection...
