DNS NSLOOKUP server failed for MX entry

For various reasons I won’t go into I’ve set up a custom DNS server for a delegated subdomain of my main domain. This DNS server is a .NET application which uses the ARSoft DNS library to respond to requests. This DNS server is working fine for A, CNAME and TXT records, but it doesn’t seem to respond to MX requests when they have been forwarded from other popular open DNS servers. NSLOOKUP responds with the message “google-public-dns-a.google.com can’t find cloud.xibis.net: Server failed” but if I use another DNS server like dns.xibis.com (the delegated subdomain DNS server) it works fine.

Here is a link to the output of the dig tool for the request:

https://www.digwebinterface.com/?hostnames=cloud.xibis.net&type=MX&showcommand=on&stats=on&trace=on&ns=resolver&useresolver=8.8.4.4&nameservers=

(Click ‘Dig’ to proceed)

You can clearly see at the bottom of the trace output that my DNS server is responding with the MX records, but the Google DNS server won’t forward them for some reason.

The reason I’m doing this is to set up this domain for use with GSuite/Gmail.

Does anyone have any suggestions as to why this might be happening?

Thanks!

Magento2.2 – – Failed to read session data

If you open the front end with multiple tabs in the browser, the following error is output:.

Exception #0 (Exception): Warning: session_start(): Failed to read session data: user (path: /var/opt/remi/php71/lib/php/session) in /var/www/html/primary/vendor/magento/framework/Session/SessionManager.php on line 189 

The www.conf file specifies the location of the session as follows:.

php_value[session.save_path]    = /var/opt/remi/php71/lib/php/session 

The permissions for saving sessions are set as follows:.

The configuration problem is complete, but an exception message is printed. Please tell me how to fix it.

Creating an Azure VM from VHD failed “is not a valid resource reference”

I am trying to deploy virtual smart zone to Azure via Terraform, but could not succeed many times. Also I read the article existing here. Could you please give me an advice and fix it? Thank you so much.

Here are the details: Terraform Version:

tien$   terraform -v Terraform v0.11.13 + provider.azurerm v1.27.1 + provider.random v2.1.2 

What terraform did I write:

resource "azurerm_virtual_machine" "vsz_vm" {   name                          = "vsz.az.example.com"   location                      = "$  {var.location}"   resource_group_name           = "$  {azurerm_resource_group.abc.name}"   network_interface_ids         = ["$  {azurerm_network_interface.vsz_nic.id}"]   vm_size                       = "Standard_D4_v3"    storage_image_reference {     id                          = "/subscriptions/4389d27e-249a-4f95-8bd6-3486c60945e7/resourceGroups/ABC/providers/Microsoft.Storage/storageAccounts/vszafb3c92c014b61ab/images/vscg-5.1.1.0.598.vhd"   }    storage_os_disk {     name                        = "vszOsDisk"     managed_disk_type           = "Premium_LRS"     create_option               = "FromImage"     os_type                     = "Linux"   }    os_profile {     computer_name               = "vsz.az.example.com"     admin_username              = "azure"   }    os_profile_linux_config {     disable_password_authentication = true     ssh_keys {       path                      = "/home/azure/.ssh/authorized_keys"       key_data                  = "$  {var.ssh_public_key}"     }   }    tags {     environment                 = "$  {var.environment}"   } } 

then I run terraform command

tien$   terraform init --> OK tien$   terraform plan --> OK tien$   terraform apply --> ERROR 

What issue?

Error: Error applying plan: 1 error(s) occurred: * module.azure_example_dlc.azurerm_virtual_machine.vsz_vm: 1 error(s) occurred: * azurerm_virtual_machine.vsz_vm: compute.VirtualMachinesClient#CreateOrUpdate: Failure sending request: StatusCode=400 -- Original Error: Code="BadRequest" Message="Id /subscriptions/4389d27e-249a-4f95-8bd6-3486c60945e7/resourceGroups/ABC/providers/Microsoft.Storage/storageAccounts/vszafb3c92c014b61ab/images/vscg-5.1.1.0.598.vhd is not a valid resource reference." 

The VHD file vscg-5.1.1.0.598.vhd exists in container “images” at Storage Account “vszafb3c92c014b61ab”.

Also I create the Managed Image before creating VM from Managed Image as below code:

  storage_image_reference {     id                          = "/subscriptions/4389d27e-249a-4f95-8bd6-3486c60945e7/resourceGroups/ABC/providers/Microsoft.Storage/storageAccounts/vszafb3c92c014b61ab/images/vscg-5.1.1.0.598.vhd"   }    storage_os_disk {     name                        = "vszOsDisk"     managed_disk_type           = "Premium_LRS"     create_option               = "FromImage"     os_type                     = "Linux"   }

Ubuntu Upgrade from 16.04 to 18.04 failed

today I tried to upgrade from 16.04 to 18.04 using

sudo apt-get -f upgrade 

Now, Gnome isn’t starting anymore. I tried “safe mode”, but it feels like everything is giving me failure notices.

dpkg delivers:

An upgrade from "xenial" to "bionic" is not supported with this tool 

failsafeX delivers a black screen. “network” delivers:

grep: /etc/resolv.comf: No such file or directory 

Does anyone know, what to do?
