We are aware that many partners may have problems with their probes upgrading to 2023.1. Before upgrading N-central to 2023.1, please download and review the instructions in the following zip file: Probe Upgrade Instructions.

What’s new in N-central 2023.1

N-central 2023.1 is packed with both fixes as well as a new feature! Please see below for more information on our new feature, and the list of fixed items!

Customizing the N-central UI Port is now GA!

An exciting new feature in 2023.1, is the ability to control the port at which the N-central UI runs. The goal of this feature is to allow our on-premise N-central Partners to increase the security of their N-central instance by controlling how and if their N-central UI is exposed to the internet. This feature is not enabled by default on upgrades and can be enabled via Administration > Mail and Network Settings > Network Setup. New installations of N-central 2023.1 will have 8443 as its default UI port. You can learn more here.

Automation Manager 2.60

Automation Manager 2.60 is now available and included in N-central 2023.1. This version of Automation Manager focuses on bugfixes.

Mac Agent 1.2.4

Along with N-central 2023.1, the new Mac Agent 1.2.4 was released and contains a fix for the missing CPU and Memory graphs as well as additional improvements!

Major bug fixes

Alongside 40+ other items shown below, there have been several key improvements and fixes in this build! We have resolved a highly impactful issue with the inability to load AMPs when logging in as an IDP linked user (NCCF-35682). We have also resolved an issue with establishing a RDP (NCCF-49091) session as well as an issue with Report Manager data exports (NCCF-49480).

Upgrade paths and notes

After the upgrade to N-central 2023.1, an additional restart of the Windows Agent Service, Windows Agent Maintenance Service, and Windows Software Probe Service (Manually or Scheduled Task) or a full device reboot (not hibernate or sleep) may be required on Windows devices with misconfigured AMP-based services in order for them to go back to Normal state.

Upgrade versions

To upgrade to N-able N-central 2023.1, your N-able N-central server must be running one of the following versions:

View versions:
  • N-able N-central 2022.6.0.20+
  • N-able N-central 2022.7.0.22+
  • N-able N-central 2022.8.0.14+
  • N-able N-central 2023.1.0.12

Notes the following when upgrading N-able N-central.

Tasks may expire if the agent on an associated device is being upgraded when the task is scheduled to be completed. Agent upgrades are normally short in duration but may be delayed if a re-start of the device is pending.

IMPORTANT: If you are a Partner running N-central in Azure, review the following article to avoid any potential issues with the upgrade to this release. We have identified an issue that impacts our Azure hosted N-central partners. Fortunately, our team has steps to resolve the issue.

Known Limitations

These items for the current version of the N-able N-central software is composed of material issues significantly impacting performance whose cause has been replicated by N-able and where a fix has not yet been released. The list is not exclusive and does not contain items that are under investigation. Any known limitations set forth herein may not impact every customer environment. The N-able N-central software is being provided as it operates today. Any potential modifications, including a specific bug fix or any potential delivery of the same, are not considered part of the current N-able N-central software and are not guaranteed.

Active Issues

When exporting a large list of Active Issues items to PDF format at either the System or Service Organization level, the server may fail. Exporting to CSV format does not cause this problem.62860
Agents and Probes

Communication issues may be encountered for N-able N-central Probes installed on Windows servers that have multiple NICs. For more information, refer to “KBA20020: Configuring A Server With Multiple NICs” in the online Help.67778
Automation Manager

Running Automation Manager Policies created using Automation Manager 1.6 or earlier may result in Failed to create an EndDate … errors if the Policies are run on a computer using a different date format. This issue does not affect Policies created using Automation Manager 1.7 or later.65712
AV Defender and Backup Manager – D2D

The About Backup Manager dialog box no longer indicates if the Backup Manager software is licensed.68226
Custom Services

Custom services may appear as misconfigured when the system locale of the device is not set to English. For example, in Portuguese the default decimal in c#/.net is not a period, “.”, it is a comma, “,”. If you are having this issue, please contact N-able Technical Support.65288
Core Functionality

Installing N-able N-central on Servers that have an Nvidia Video Card
Due to a bug in CentOS 7 with Nvidia’s “Nouveau” driver, installing N-able N-central on servers that have an Nvidia video card may result in the N-able N-central console showing a blank screen, or displaying an Anaconda Installer screen with an error message about the video card driver.

Chrome 42.x does not support NPAPI plugins which means that Java and Direct Connect will not function with that browser version. When attempting to open remote control connections in Chrome 42.x, users will be repeatedly prompted to install either Java or the NTRglobal plugin with no successful connections made. To resolve this issue, perform the following:

1. In the Chrome address bar, type chrome://flags/.
2. Under Enable NPAPI, click Enable.
3. Restart Chrome.

Modifying a Dashboard that is associated with a large number of services may cause performance issues when using the Firefox browser.70326
PSA Integration

In some instances, tickets closed in PSAs are not being cleared in N-able N-central. This is likely because the ticketing recipient profile in N-able N-central has Do not change the Ticket Status selected (in order to manually configure tickets). Then, when the ticket is removed in the PSA, N-able N-central will not be able to update/resolve the ticket’s status and new tickets
cannot be created for the same issue. Until a solution is available through the UI for this situation, the work around is to set a Return to Normal status and set a non-used status in the ‘updatable statuses’ section or set the same status as the return to normal one. This will cause N-able N-central to add a note to the ticket on return to normal but will not alter the ticket’s
status. This will allow the stale ticket check to remove the ticket from the system.

After re-naming, the Names of files or Registry entries may not be displayed properly in the File System window and the Registry window of the Tools tab when using Internet Explorer.68149
User Access Management

Login window reappears when new tab is loaded.

When already logged into N-central and a user opens a new tab and browses to N-central from this new tab, the login screen reappears yet the user is already logged in. The left hand navigation is functional.

Available Ciphers for Non Agent/Probe Communication with N-central

View ciphers




TLS 1.2:





End of support

The following are being deprecated in a future release of N-able N-central:

Linux Agent SupportDue to declining usage in the field, the N-able N-central Linux agents will stop supporting CentOS 6, Ubuntu 14.04 and the 32- bit version of Ubuntu 16.04, in a future release.
Internet Explorer 11Due to declining usage in the field, a future release of N-able Ncentral will drop support for the Internet Explorer 11 web
AV Defender 5.xAs of next major release for those of you still utilizing the AV5
Bitdefender Antivirus be advised that monitoring from our AV5
agents will no longer continue. As a result this will leave your
environments in a vulnerable state. We encourage you to
review your agents to ensure you are now utilizing our latest
AV6 agents. Reminder that our online help for Security Manager is available for your reference.
Windows 8.1/Windows Server
2012 R2
As older Windows Server and Desktop Operating Systems
transition into Microsoft’s Extended Support Phase and
beyond, they are no longer receiving OS level TLS version and
cipher updates (SCHANNEL). As the .NET Framework relies on
SCHANNEL for TLS based communications, and as newer
vulnerabilities are discovered in the ciphers available to these
older Operating Systems, the available Strong Cipher list for
these devices continues to shrink. We continually review the
ciphers used by N-central’s Modern Security Profile, to ensure
we offer only secure ciphers. At this time, there are only two (2)
secure RSA key based ciphers available to Windows Server 2012
R2/Windows 8.1 and older. N-central will endeavor to support
these two ciphers in our Modern Security profile for as long as
they remain secure, but there may come a time where we will
need to drop Official support for these Windows versions
before the end of their Extended Support Phase. If/when this
does occur, they will still be able to connect if you switch to the
Legacy Security Profile, but this will reduce the security of all
devices connecting to your N-central server.

If you monitor Windows Server 2003/2008/Windows XP/Vista
devices, we would like to advise you that we will be dropping
support for the “TLS_RSA_WITH_3DES_EDE_CBC_SHA” cipher in a future release. Coming changes to the web front end that will support TLS 1.3, have been identified as also disabling “TLS_RSA_WITH_3DES_EDE_CBC_SHA” due to the required version of OpenSSL. Fully patched Windows Server 2008/Vista devices should be able to connect to N-central on the Legacy
Security profile, using one of the newer, but still weak ciphers.
Windows Server 2003/XP will no longer be able to communicate
over TLS/HTTPS at that time (using a site-to-site VPN between
your firewall devices, and connecting over HTTP may still work).
32-bit versions of
the Windows, Linux and macOS
operating systems
The number of 32-bit Operating Systems monitored by Ncentral has continued to drop over the past few years. Windows Agents/Probes have historically been 32-bit, with some 64-bit specific components. In a future release, we intend to convert the Agent and Probe code base to be a native 64-bit application; this will mean a hard deprecation of support for 32-bit Windows versions. N-central’s Linux and macOS agents will follow a similar path.

N-able N-central System requirements

The following requirements are for typical usage patterns, acknowledging that some patterns may require greater system resources for a N-able N-central server than others.

If you have any questions about how your needs affect the system requirements of your N-able N-central server, contact your Channel Sales Specialist or email

ProcessorServer class x86_64 CPUs manufactured by Intel or AMD (i.e. Xeon or EPYC). Please refer to the Red Hat Hardware Ecosystem for further details
You do not need to install a separate Operating System to run N-able N-central. The N-able Ncentral ISO includes a modified version of CentOS 7, based on the upstream Red Hat Enterprise Linux 7.
The physical server used to install N-able N-central in a bare metal environment must be certified to run Red Hat Enterprise Linux 7.7 (x64) by Red Hat, or the hardware vendor, without any additional drivers. Please check the Red Hat Hardware Ecosystem for details.

Server Grade hard drives connected to a RAID controller with a Battery/Capacitor Backed Cache are Required. Examples include 10K+ RPM SCSI or SAS drives, Enterprise Grade SSDs or NVMes for bare metal and virtualized hosts, or a Fibre Channel connected SAN with Enterprise Grade hard drives for virtualized hosts (Fibre Channel cards can be used for bare metal if they are configured in the pre-boot environment and do NOT require vendor-provided drivers).

Although Desktop Hard Drives will work with the Operating System, they do not meet the minimum throughput required for the back-end Database of N-able N-central.

For more details, please refer to the Red Hat Hardware Ecosystem to see if your current hardware will work with our customized version of CentOS 7.

System requirements by number of devices managed

The table below lists the minimum specifications required to manage the number of devices indicated (based on average usage). Performance can be improved by exceeding these requirements. When determining your hardware requirements, consider any growth in managed device count that may occur over time.

Number of devicesCPU CoresMemoryStorage
Up to 1,00024 GB RAM80 GB RAID
Up to 3,00048 GB RAM150 GB RAID
Up to 6,000816 GB RAM300 GB RAID
Up to 9,00001224 GB RAM450 GB RAID
Up to 12,0001632 GB RAM600 GB RAID

Up to 24,0003480 GB RAM1.2 TB RAID


  1. Server Grade hard drives connected to a RAID controller with a Battery/Capacitor Backed Cache, are required to ensure performance and unexpected power-loss data protection.
  2. In a virtualized environment, hard drives for the N-able N-central server must not be shared with any other applications or VM guests that have significant I/O workloads. For example, Report Manager, SQL Databases, E-Mail Servers, Active Directory Domain Controllers, SharePoint, or similar should not be installed on the same physical hard drive as N-able N-central.
  3. N-able recommends two or more hard drives be placed in a redundant RAID configuration. With two drives, RAID 1 must be used. With more than two drives, RAID 1+0 or RAID 5 are recommended. RAID 6 is an option on servers with less than 1,000 devices (the additional write latency of RAID 6 becomes an issue above 1,000 devices).
  4. N-able recommends more, smaller disks in a RAID array, as opposed to fewer larger disks. Databasebacked applications, like N-able N-central, have better write performance with an increased number of parallel writes (hard drives).
  5. If using Solid State Drives (SSDs), N-able requires Enterprise Grade, SLC based (or better) SSDs with a SAS interface, or Enterprise Grade NVMes. SSD and NVMe drives must have an endurance rating of at least 0.2 DWPD (Drive Writes Per Day), and at least 2 physical disks in a redundant RAID array. On Bare Metal servers, the RAID array must appear to the operating system as a single Block or NVMe Device. Currently, many PCIe and NVMe drives do not meet this last requirement and would only work in a virtualized environment.
  6. Configure the RAID controller to use the default stripe size and a Read/Write cache of 50%/50%.

The underlying customized version of CentOS 7 has certain hardware limits that are consistent with the upstream Red Hat Enterprise Linux 7 distribution. Of note are the following:

Minimum disk space80 GB
Maximum physical disk size (BIOS)2 TB
Maximum physical disk size (UEFI)50 TB
Required minimum memory4GB for 4 or fewer logical CPUs

1GB per logical CPU for more than 4 logical CPUs
Maximum memory12 TB
Maximum logical CPUs768

Due to the ecosystem of different hardware, N-able does not certify specific hardware configurations. Instead we rely on the upstream Red Hat Enterprise Linux and hardware vendor testing and certification.

Examples of servers that have been Red Hat certified include HPE ProLiant DL360 Gen10 and Dell PowerEdge R620.

Please consult with your hardware vendor to ensure that any server to be used for a bare metal installation meets the above requirements, and is Red Hat Enterprise Linux 7.7 certified, without the need for additional

N-able recommends that for any Bare Metal server, two or more SAS 10k or faster hard drives be placed in a RAID array to improve redundancy. RAID 1+0 or RAID 5 are supported (at the hardware RAID BIOS level). RAID 6 is an option on servers with less than 1,000 devices (the additional write latency of RAID 6 becomes an issue above 1,000 devices).

Support for virtualized environments

N-able supports VMware ESX Server 6.0 or newer and Windows Server 2012 R2 Hyper-V or newer LTS versions. N-able recommends use of the latest stable versions of VMware or Hyper-V in order to ensure the best performance, feature set and compatibility with N-able N-central.

Hyper-V on Windows Desktop Operating Systems not Supported.

N-able N-central installed on a virtual machine running on a Desktop Operating System (such as HyperV on Windows 10, Virtual Box, Parallels, VMWare Fusion or similar) is not a supported configuration. If
you are using Windows Hyper-V, it must be installed on a supported server class Windows Operating

Windows Server Semi-Annual Releases are not Supported.

Only Long-Term Support (LTS) versions of the Windows Server Operating System are supported as a
Hyper-V host for N-able N-central. Microsoft currently releases “Semi-Annual Release” versions of
Windows Server as a technology preview for the next LTS version. Due to their technology preview
status, these “Semi-Annual Release” versions of Windows Server are not supported as Hyper-V hosts
for N-able N-central.

About virtualization

Virtualization provides an abstraction layer between the hardware and the Operating System which permits the operation of multiple logical systems on one physical server unit. The table below includes considerations when using this deployment method.

It is impossible to guarantee the scalability or performance of a N-able N-central server deployed on a Virtual Machine due to:
1. Variability in field environments resulting from host server configurations,
2. The number of virtual guests run on the host server, and
3. The performance of the underlying host hardware.
SupportabilityN-able supports N-able N-central software deployed on VMWare ESX/ESXi 6.0 or newer, Windows Server 2012 R2 Hyper-V or newer LTS releases, Microsoft Azure and Amazon AWS EC2 in the same way that we support N-able N-central deployed on Bare Metal. This support is limited to the components (Software and Operating System) shipped with Nable N-central and does not include the troubleshooting of virtualization systems nor of
performance issues related to environmental factors.

N-able recommends reaching out to your hardware or virtualization vendor for support on the underlying virtualization and hardware components. Any assistance provided by Nable Support for virtualization or hardware issues is on a best-effort basis only. In the event of serious performance problems, we might ask you to migrate a virtualized N-able N-central system to a physical hardware deployment.
In Windows Server 2016 Hyper-V or newer deployments, it is recommended to create a new Generation 2 VM. When configuring the VM virtual hardware, if you choose to enable Secure Boot, please select the Microsoft UEFI Certificate Authority template.

For VMWare ESX/ESXi deployments, it is recommended to select the Red Hat Enterprise Linux 7 guest OS template, then under the Boot Options, select the UEFI Firmware.
N-able recommends using the VMXNET3 network card in VMWare. When the VM is configured as Red Hat Enterprise Linux 7, it will use VMXNET3 by default.

Unless you are using Network Interface Bonding, N-able N-central requires only one (1) network adapter added to the VM configuration. Multiple network adapters that are not used in a bonding configuration can cause connectivity and licensing issues.
MAC AddressesBy default, most virtualization environments use a dynamically assigned MAC address for each virtual network card. As your N-able N-central license is generated in part by using the MAC address of its network card, it is required to use a statically assigned MAC address in order to avoid becoming de-licensed.

Recommended configuration for the virtualized server

Although provisioning virtual disks as “thin” or “thick” results in nearly-identical performance, thick
provisioning is recommended, particularly when more than 1,000 devices will be connected to your Nable N-central server.

  • Assign the highest resource access priority to N-able N-central, as compared to other guest VMs.
  • Do not over-provision resources (Memory, CPU, Disk) on the virtualization host. Over-provisioning these resources can causes memory swapping to disk, and other bottlenecks that can impact guest system performance.
  • Ensure that the system has enough RAM and hard drive space to provide permanently allocated resources to the N-able N-central guest.
