N-central Help

Hardware requirements

For the minimum hardware requirements for the SolarWinds N-central 12.1 central server, click here.

Devices

The following are the minimum hardware requirements for devices that will have SolarWinds N-central agents and probes installed on them:

  • RAM: 512 MB
  • Disk space: 500 MB
  • Processor: x86 or x64

Agents and probes are not supported on systems using Itanium processors.

Port access requirements

Access must be permitted to the following ports:

  Port Number PORT LOCATION   Description
SolarWinds N-central Server Managed Device
Inbound Outbound Inbound Outbound
20       Used for FTP connections, particularly when configured for backups.
21       Used for FTP connections, particularly when configured for backups.
22     SSH - used for remote control sessions. Configure the firewall to allow access from the Internet to this port on the SolarWinds N-central server.
25       SMTP - used for sending mail.
53       Used for DNS.
80 HTTP - used for communication between the SolarWinds N-central UI and agents or probes. Configure the firewall to allow access from the Internet to this port on the SolarWinds N-central server. This port must also be open for outbound traffic if the SolarWinds N-central server is monitoring the HTTP service on a managed device.

Inbound access to port 80 on the SolarWinds N-central server can be blocked provided that all agents are configured to use HTTPS and the
SolarWinds N-central server is accessed over port 443 using HTTPS.

123       Used by the NTPDate service which keeps the server clock synchronized. Normally using UDP (although some servers can use TCP).
135       Used by agents and probes for WMI queries to monitor various services.
139       Used by Agents and Probes for WMI queries to monitor various services.
443   HTTPS - used for communication between the SolarWinds N-central UI and agents or probes. Port 443 is the TCP port needed for SSL (HTTPS) connections. Configure the firewall to allow access from the Internet to this port on the SolarWinds N-central server. This port must also be open for outbound traffic if the SolarWinds N-central server is monitoring the HTTPS service on a managed device.
445       Used by agents and probes for WMI queries to monitor various services.
1433   * * * Outbound on the SolarWinds N-central server, port 1433 is used by Report Manager for data export. On managed devices, it is also used by agents (inbound) and probes (outbound) to monitor Backup Exec jobs.
* Port access is only required if you have installed the corresponding product. For example, access to port 1433 is only required if you have installed Report Manager or if you are managing Backup Exec jobs.
2195       Used to send Mobile Device Management notifications to APNS servers at gateway.push-apple.com.akadns.net.
2196       Used to send Mobile Device Management notifications to APNS servers at gateway.push-apple.com.akadns.net.
8014       SolarWinds N-central's Backup Manager requires access to port 8014. This value cannot be modified.
10000       HTTPS - used for access to the SolarWinds N-central Administration Console (NAC). The firewall must be configured to allow access from the Internet to this port on the SolarWinds N-central server.
10004     SolarWinds N-central agents must be able to communicate with a probe on the network over port 10004 for probe caching of software updates to function properly.
11438     To use Direct Connect or Remote Control for remote control connections, port 11438 on the target device must be accessible for outbound traffic.
15000     For downloading software patches, port 15000 must be accessible for inbound traffic on the probe device while it must be accessible for outbound traffic on devices with agents.

The table below outlines the TCP open port configurations required to send/receive push notifications for MDM.

Firewall configuration requirements

Secure Shell access is required for SolarWinds MSP to sign in and provide you with technical support as well as for remote control functionality.

Firewall configurations should not prevent outbound HTTPS connections from the SolarWinds N-central server or Direct Connect remote control sessions will not function properly.

The SolarWinds N-central server must be able to resolve (and access over FTP - TCP ports 20, 21, UDP ports above 1024 for Passive Transfer) the following domain name:

  • send.solarwinds.com

The SolarWinds N-central server must be able to resolve (and access over HTTP TCP port 80) the following domain name:

  • sis.n-able.com

The SolarWinds N-central server must be able to resolve (and access using HTTPS TCP port 443) the following domain names:

  • update.n-able.com
  • feeds.n-able.com
  • servermetrics.n-able.com
  • push.n-able.com
  • scep.n-able.com
  • licensing.n-able.com
  • microsoft.com

Probes with patch caching enabled

When patch caching is enabled, the probe needs to have access to software vendor's web sites to download the installation software. The probe stores the installation software in the patch cache, and accesses it during patching maintenance window.

Adding the web sites below to the firewall white list ensures that patching can run without interruption due to blocked downloads.

Agents only requires access to the Server In The Sky (http://sis.n-able.com).
