Linux Backup Server Cannot Communicate with Any Node in the Network

Symptom

Linux Backup Server cannot communicate with any node in the network.

Solution

If the Appliance windows server cannot communicate with any node in the network, the Linux Backup Server cannot also communicate with any node.

Follow these steps:

  1. Verify if the node is accessible from Appliance windows server.
  2. Navigate to the following location to verify if network adapter LinuxBkpSvr exist as shown below:

    Control Panel>Network and Internet>Network Connections

  3. If LinuxBkpSvr is unavailable, navigate to the following location and verify if flag file adapterNameChanged.flag exists:

    4. C:\Program Files\Arcserve\Unified Data Protection\Engine\BIN\Appliance

    If existing, remove the adapterNameChanged.flag file.

  4. Verify if all available network interfaces and LinuxBkpSvr are added to NAT as shown below.

    5. If all network interfaces and LinuxBkpSvr are already listed, verify if different physical network interfaces are connected with different sub network. This action resolves the communication problem of Linux Backup Server.

    If all the network interfaces and LinuxBkpSvr are listed, continue with next step.

  5. Delete the file dhcpdone.flag from the following location:

    6. C:\Program Files\Arcserve\Unified Data Protection\Engine\BIN\Appliance

  6. Using Command Line, enter folder C:\Program Files\Arcserve\Unified Data Protection\Engine\BIN\Appliance and run resetdhcp.ps1 as shown below.

    7. C:\Program Files\Arcserve\Unified Data Protection\Engine\BIN\Appliance>powershell .\resetdhcp.ps1

    When the script runs successfully, the communication issue for the Linux Backup Server is resolved.
