Network Requirements

This section covers the following topics:

  1. Master Server Network Requirements
  2. Node Agent Network Requirements
  3. Proxy Agent Network Requirements

Master Server Network Requirements

If you have any firewalls configured between the Master Server and

  • any hosts that need to connect to the Web Console,
  • all Agent hosts, or
  • (optional) the Ground Labs update server,

make sure that the following connections are allowed:

TCP Port Allowed Connections To / From Description
80 / 443 Inbound From: Hosts connecting to the Web Console. To allow hosts on the network to access the Web Console.
8843 Outbound To: Ground Labs update server. (Optional) To allow the Master Server to receive updates from the Ground Labs update server.
11117 Inbound From: Node or Proxy Agent hosts. To allow Node and Proxy Agents to establish a connection to the Master Server.

Node Agent Network Requirements

On Node Agent hosts, the following connections must be allowed:

TCP Port Allowed Connections To / From Description
11117 Outbound To: Master Server. A Node Agent establishes a connection to the Master Server on this port to send reports and receive instructions.

Proxy Agent Network Requirements

Proxy Agents must be able to connect to:

  • the Master Server on port 11117
  • the Target host or service

Details can be found in these sections below:

Agentless Scans

Make sure that the Target and Proxy Agent host fulfill the following requirements:

Target Host Proxy Agent TCP Port 1 Requirements
Windows host Windows Proxy Agent

  • Port 135, 139 and 445.

For Targets running Windows Server 2008 and newer:

  • Dynamic ports 9152 - 65535

For Targets running Windows Server 2003 R2 and older:

  • Dynamic ports 1024 - 65535

WMI can be configured to use static ports instead of dynamic ports.
  • Bi-directional SCP must be allowed between the Target and Proxy Agent host.
  • The Target host security policy must be configured to allow the scanning engine to be executed locally.
  • The Target credential must have the required permissions to read, write and execute on the Target host.
Linux or UNIX host Windows, Linux or UNIX Proxy Agent
  • Port 22.
  • Target host must have a SSH server installed and running.
  • Proxy Agent host must have an SSH client installed.
  • Bi-directional SCP must be allowed between the Target and Proxy Agent host.
  • The Target host security policy must be configured to allow the scanning engine to be executed locally.
  • The Target credential must have the required permissions to read, write and execute on the Target host.
macOS host macOS Proxy Agent
  • Port 22.
  • Target host must have a SSH server installed and running.
  • Proxy Agent host must have an SSH client installed.
  • For macOS Ventura 13 and above, the "Full Disk Access" feature must be enabled for sshd-keygen-wrapper in the Proxy Agent host.
  • Bi-directional SCP must be allowed between the Target and Proxy Agent host.
  • The Target host security policy must be configured to allow the scanning engine to be executed locally.
  • The Target credential must have the required permissions to read, write and execute on the Target host.

1 TCP Port allowed connections.

Network Storage

Protocol/Target Type Destination TCP Port (default) Description
CIFS/SMB server

445

*See description for additional ports.

To scan Windows remote file shares via CIFS.

Additional ports

For Windows 2000 and older:

  • 137 (UDP)
  • 138 (UDP)
  • 139 (TCP)
SSH server 22 To scan Unix or Unix-like remote file shares via SSH.
NFS server

2049 (TCP or UDP)

*See description for additional ports.

To scan NFS file shares.

Additional ports

NFSv4 requires only port 2049 (TCP only).

NFSv3 and older must allow connections on the following ports:

  • 111 (TCP or UDP)
  • Dynamic ports assigned by rpcbind.

rpcbind assigns dynamic ports to the following services required by NFSv3 and older:

  • rpc.rquotad
  • rpc.lockd (TCP and UDP)
  • rpc.mountd
  • rpc.statd

To find out which ports these services are using on your NFS server, check with your system administrator.
