PubTester

PubTester is a program written in cross-platform script language TCL/TK, and using multi-threaded scheme to check if the given IP addresses are valid pub ftp servers. It retrieves IPs and relative information from the input and checks their upload access, download access, download speed, delete access, resumable access and the possibility to create hidden and undeletable directories. The program takes the following format as its input, which can be automatically generated by the scanner program Grim’s Ping:

……

XX.XXX.XXX.XX (IP address)
-------------
DIR:           /
DELETE STATS:  deletable
RUNNING OS:    Windows_NT
RESUMABLE:     Yes
FXP STATS:     non-FXPable
SEND SPEED:    5121.60 bytes/s

XX.XXX.XXX.XX
--------------
DIR:           /
DELETE STATS:  deletable
RUNNING OS:    Windows_NT
RESUMABLE:     Yes
FXP STATS:     non-FXPable
SEND SPEED:    4497.39 bytes/s
……

The entire checking procedure is briefly shown as below:

Import IP address information from the scanning result produced by Grim’s Ping.

Configure the parameters used by checking procedure.

The checking is in progress.

The ftp communication is logged which can be viewed on-the-fly.

Users are allowed to manage the check results, by sorting them by speed, deleting invalid pub addresses, and even save them for future test.

This program is neither a scanner nor a hacker program. It is mainly designed to help system administrators to identify potential hazard of their ftp servers. If you would like to have a copy of this program, please send email to kwang@cs.sunysb.edu and state what you are going to use it for.
