@sebastian-roth Ahh, I didn’t see that either. Okay, so in DHCP I changed the router to 192.168.22.1 and range starting IP to .20

In fogsettings, I changed both routeraddress and plain router from 192.168.22.11 to 22.1

The test client gets online just fine now.

Thank you again, Sebastian!

@sebastian-roth said in No Subnet Declaration for virbr0 After Upgrade to 1.5.9:

Does this gateway provide DNS as well? Either as a DNS service or by relaying the DNS queries to an upstream DNS server?

It must be, because this Fogserver instance is more than 2 years in production and has always worked great. Before upgrading to 1.5.9, the Fogserver and DHCP clients under it had internet access. After the upgrade, the Fogserver gets internet access/resolves webpages while the DHCP clients under it get LAN with “no internet access” though they can ping external sites.

I just rebooted everything and there’s still no resolution.

@sebastian-roth 192.168.22.1 is the Gateway IP/Subnet for the VLAN 22 this Fogserver is connected to. The main Gateway IP/Subnet/Name Server is 192.168.1.1.

The Fogserver surfs the web just fine, though DHCP clients don’t.

eth0 DNS address is set to Automatic.

@sebastian-roth Yes, I am using eth0 and DHCP works great. The problem is the clients don’t have internet access. They can ping external sites but webpages don’t load/resolve.

Here’s a screenshot of the Windows network diagnostic:

Fogserver is a VM in Synology Virtual Machine Manager and tagged to a VLAN (22)

@sebastian-roth The kernel update works now and image capture is successful.

I’ll start a new topic on the networking issue.

Thanks Sebastian!

@sebastian-roth Okay, I did misunderstand the fogstorage piece, thank you. I set it back to fagmaster and re-ran the installer. Everything went well and Fog is now up to date, however, now dhcpd has an error:

No subnet declaration for virbr0 (192.168.122.1). Ignoring requests on virbro. If this is not what you want, please write a subnet declaration in your dhcpd.conf file for the network segment to which interface virbr0 is attached.

I updated the TFTP FTP username from fog to fogproject and the kernel update succeeded.

I then re-ran the installer, which updated the database credentials to fogstorage. I re-ran the installer after updating the settings file with the fogstorage credentials, and receive a new error at the end of the install:

HTTP request sent, awaiting response… 500 Internal Server Error
Error 1142 (42000) at line 1: INSERT,UPDATE command denied to user ‘fogstorage’@‘localhost’ for table ‘globalSettings’

I’m still able to login, the database looks good the instance says that everything is up to date.

I don’t have anything on the bench to test with, so will do that a little later today.

@sebastian-roth I used git clone https://github.com/FOGProject/fogproject.git to get the installer.

There is a Linux account named fogproject.
