![]() If there are any SolarWinds Platform alerts configured to launch RTNForwarder.exe as an action, that action is disabled. You don't need to specify an executable or provide command line arguments.ĭuring an upgrade, the installer makes the following changes:Īny LV or LA rules (preconfigured or custom) that performed the action of launching RTNForwarder.exe are automatically updated to perform the new Real-Time Config Change Detection action instead. The Real-Time Config Change Detection action requires no configuration. In 2023.2.1 and later, this action is used (instead of Run External Program) in rules configured for real-time change detection. This action is available only if NCM or Hybrid Cloud Observability Advanced is installed. The Log Viewer (LV) and Log Analyzer (LA) now include a new action called Real-Time Config Change Detection. This program is still present on your SolarWinds Platform server, but it is not used. The program RTNForwarder.exe is no longer launched to download the updated configuration file. Real-time change detection (RTCD) works as expected. Network Configuration Manager 2023.2 Release Notesįor information about new features and fixes in the SolarWinds Platform, see the SolarWinds Platform 2023.2.1 Release Notes. For information about the 2023.2 release, including EOL notices and upgrade information, see: the router runs a TFTP client and you need to host the firmware image on a TFTP server.Network Configuration Manager 2023.2.1 is a service release providing bug and security fixes for release 2023.2. The below article mainly advises on the first mode of recovery, i.e. many Netgear routers, run a TFTP server in recovery mode, and you need to upload the firmware to the device using a TFTP client. Other devices do not have automatic pull function and they need you to manually TFTP copy commands in recovery mode to download the firmware via TFTP and initiative the install. ![]() Some devices then will automatically pull the network-provided firmware file over TFTP network protocol to the OpenWrt and hopefully recover with a successful emergency flash process. Then device with the broken firmware then has to be started up in TFTP recovery mode. There are two potential modes of operation:įor many routers, the recovery process requires you to host the firmware image on a TFTP server on your computer. In case of a failed flash process or in case of a misconfiguration, the device's boot loader usually remains untouched and can therefore be used to reflash the firmware and recover the device. On most devices, the vendor provides a boot loader on a discreet partition that is untouched by firmware updates. If you keep TFTP-Server running or if you keep the TFTP-client tool available to run anytime, then abusive hackers can abuse/exploit it, to load harmful firmware and/or to change sensitive security settings inside your existing router firmware 1, 2, 3, 4, 5, 6, etc. (frwl rule # 3) TFTP traffic is Not-Allowed when originated from Internet-ip-address (aka: NON private- LAN ip-address ranges)Īnd you must also make sure to do this: after your develop / troubleshooting etc work is done or when you pause to goto other work, then make sure the TFTP-server and TFTP-client both are completely disabled in your OS/distro : turn off TFTP-Server service / process, disable TFTP-server startup script file, and move the TFTP-client ( tftp) & the TFTP-server ( tftpd) executable / binary ( bin) files out of all folders mentioned in your PATH variable, into a different folder (which is NOT in the PATH variable), and also move bin files out of the folder which is mentioned in startup-script (if such is used).
