Disable IPv6 on FileWave Server Components

What

FileWave Server, Booster, and Imaging Virtual Server (IVS) components should use IPv4. Enabling IPv6 on FileWavethese Server,server Boosters,components can cause unexpected communication or IVSservice-discovery could lead to unexpected networking issues. IPv6 is a complex networking protocol that, while supported on macOS and Linux operating systems, is not optimized for use with FileWave. Therefore, it's recommended to use IPv4 for more stable and predictable behavior.problems.

When/Why

ThisUse informationthis isguidance particularlywhen importantinstalling foror organizationstroubleshooting lookinga toFileWave avoidServer, networkingBooster, issuesor relatedIVS. toFileWave theclients can operate on networks that use ofIPv6, but IPv6 should remain disabled on the FileWave Server, Boosters, and IVS. While FileWave clients can function correctly with IPv6, best practice dictates that IPv6 should be disabled on the server components to ensure optimal performance and stability.themselves.

How

For macOS

To disable IPv6 on macOS, you can executeRun the following commandscommand in Terminal, replacing en0 if the Terminal:active network service uses a different interface:

# Disable IPv6 for a specific network interface (e.g., "en0")
networksetup -setv6off en0

For Linux

On Linuxa systems,custom youDebian caninstallation, disable IPv6 usingwith the following steps:

  1. Edit the /etc/sysctl.conf file:
sudo nano /etc/sysctl.conf
  1. Add the following lines to the file:
# Disable IPv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
net.ipv6.conf.tun0.disable_ipv6 = 1

  1. Save and close the file.

  2. Reload the sysctl settings:

sudo sysctl -p

  • macOS: Open Terminal and run ifconfig to check the network interfaces.
  • Linux: Execute ip a or ifconfig to inspect the network configurations.
