TFTP server general options

SolarWinds does not recommend usage of Trivial File Transfer Protocol (TFTP) in KCT due to potential security vulnerabilities. If TFTP must be used, it is highly recommended to take precautions and limit its exposure

To set general server options:

  1. Go to Options > Setup.
  2. Select the TFTP Server tab.
  3. Select the General Options tab.
Automatically start TFTP server on program startup Starts the TFTP server when CatTools starts.
TFTP Port The port number the server listens on. This is normally port 69.
TFTP Bind to

The IP address of a network interface card to bind to.

Leave the field blank to use the default card.

Upload folder The folder that contains files to be uploaded to devices from CatTools.
Download folder The folder that contains files downloaded from devices by CatTools.
Allow overwrite of existing files Allow files currently in the folder to be overwritten by files of the same name.
Allow automatic creation of sub folders Allow sub-folders to be created automatically during a download.
Remove completed sessions from display after

Remove the messages created from a TFTP session from the display tab after the specified number of seconds.

Maximum file size that can be created

Set the maximum file size in MB that the server can create.

  • The default value is 20MB.
  • TFTP clients may also have a limit to file size they can send. There appears to be a known limitation in some TFTP clients to a file size of about 32MB, which corresponds to using the standard protocol block size of 512 bytes.
  • If your network and devices are capable of handling larger block sizes, then you may be able to create much larger files.
  • There are no options in CatTools to specify a block size to use; block sizes are negotiated between the TFTP Client and Server.
