Why am I receiving alerts on my network management card about "unauthorized FTP attempts" from the IP of my PRTG network monitor tool?
"Unauthorized FTP attempts" alerts are seen in the Network Management Card (NMC)
Devices that utilize APC network management, including but not limited to UPS's, PDU's and ATS's
All serial numbers
All firmware revisions
It is possible to create an FTP sensor in the PRTG network monitoring software. Without the proper username/password configured, the monitor will attempt to login via FTP every scan, which will create frequent events on the network management card.
Properly configure credentials in PRTG, or remove the FTP sensor. More information can be found on the PRTG knowledge base here
