PumpKIN is a program designed to send and receive files over the net while having T42 or Wintalk session running using TFTP () protocol. It includes full-functional TFTP server/client so it may be useful for maintaining CISCO routers and other network equipment.

Enjoy!

This is a simple program for file exchange between two parties. It allows you to send files over the network to your party while having a T42 or Wintalk conversation. It uses open sessions to determine IP address of your party. Also you may use it as a TFTP client/server by itself. To get/put files from/to TFTP server you need to enter host name/IP address manually in the Request Dialog.

To Abort transfer(s) currently in progress - select transfer(s) you want to terminate in the list and click Abort xfer button.

You may want to hide PumpKIN window and leave it as a tray icon only. Just click the icon in the tray or simply close the window.

Use Options button to set PumpKIN options.

When the file is requested from your TFTP server you may choose to Grant Access to this file or to Deny Access. If you hesitate to answer for Confirmation timeout (default - 30 seconds) PumpKIN defaults to denial of all requests.

Whenever your party sends you a file you have always a choice to accept it or not. You can also save the file under a different name by choosing the Rename option. If you already have file with such name you may chose to resume transfer. No checking on file contents is done. This option may or may not work depending on remote implementation of protocol. It does work if you use PumpKIN on both ends. If you are still unsure for Confirmation timeout (default - 30 seconds) PumpKIN will make safe decision for you (deny).

Request dialog is aimed to let you form read or write request. You may set the following options:

• Local File - You can change the name of the file you're sending (or destination in case you're receiving) right here. You may also use Browse button to select the file.
• Remote File Specifies the name of file on the remote host you're requesting (in case of read request) or the name of file you want your file to appear as (in case of write request).
• Remote Host is your party's host or TFTP server you're requesting file from/sending file to. To refresh the list of your talk windows use REFRESH button.
• Type is the type of transfer as defined in . Doesn't mean much, really. Defined types are 'octet' or 'netascii'. Default is 'octet'.
• Block Size - Use this block size if remote is -compliant. If remote doesn't support this option PumpKIN will fallback to 512 bytes per block.

PumpKIN options property sheet consists of two tabs. For more information see Network and Server options.

• UDP Ports
  • Listen for incoming connections on port - specifies the port we're listening to. The default as defined in is 69.
  • Send outgoing requests to port - specifies the port we're going to send all requests to.
• Default Connection timeout - if there's no activity for specified time, transfer is considered to be dead and terminated. PumpKIN tries to propagate this value to remote as described in and if possible.
• Default Block Size - PumpKIN tries to negotiate block size with remote using this value unless specified explicitly in request. If remote doesn't support and PumpKIN falls back to 512 bytes per block.

• TFTP Filesystem root - Specifies the location of files you're transmitting or where to start looking for them from. Defaults to the directory you start PumpKIN for the first time from.
• Allow access to subdirectories - specifies whether you want allow access to the whole subtree of TFTP Root or only to the directory itself.
• Read Request Behavior - You may choose to automatically agree to give all files requested, to be prompted to confirm these operations, or to deny all requests as if you're not even here.
• Write Request Behavior - You may chose to take all files (not recommended), to prompt only if file exists already, Always prompt or Deny all requests.
• Confirmation timeout - this is the time PumpKIN will wait for you to accept or deny request before it will give up and take default action which is always deny.
