These scripts will automate the DShield submission process. The respective scripts should be configured to send reports to firstname.lastname@example.org

ipchains2dshield Contributed script by Frank Josellis
DShield support has been added to Tom Liston's LaBrea by Michael Robinton. First download LaBrea from one of the LaBrea download mirror sites and then get tarpit.dshield from the here. (This is an add-on to LaBrea. You must already have LaBrea installed.)

- The Proactive Probing Abuse Reporting System has 3 components. The first component is the script that creates the email that is sent to DShield. The second component builds an email containing just the source IP address belonging to the users ISP and the email is sent to the users ISP abuse department. The third component builds an email containing the log data for each abuse source IP address, does whois lookup to auto harvest the owning ISP's abuse reporting email address and sends the email to them.

Symantec Firewall/VPN Appliance and Nexland Router
This a perl script by Lars M. Hansen that takes the log files from the Symantec Firewall/VPN appliance (and also Nexland routers), and formats it into DShield format for submission to Dshield.

James has put together and outlined a process to submit Cisco 837 logs! Follow this link to learn how to submit Cisco 837 logs to DShield.
The general idea is that you look the scripts over and find one that best suits your needs. Download it and look through the script and change the configuration variables so they reflect your current reality.
But the first time you try the script, you might want to configure it to send a copy to yourself, instead to firstname.lastname@example.org. Then run the script and see what it sent to you. If it is what you expected, then reconfigure the script to send to email@example.com.
One possible pitfall is that several of the scripts use a file to keep track of how much of the log file has been sent. If you just did a test run, then you should look through the script and find out where the file is stored and erase it before you run the script again for real to submit your log to firstname.lastname@example.org
Even though the easiest way to run scripts like this is to run them as root, it is always dangerous to run anything as root. Consider creating a user that has just enough privileges to run the script. This can be achieved by creating a user and group called 'dshield'. The log files have to be owned by the group 'dshield' and readable by it (chmod 640). Create the cron job as this user.
Installing the script as a cron job
(You must be a user that has the appropriate privileges when doing this.)
First check to see if there are any existing cron jobs by typing crontab -l. If there are any existing jobs, make a safety backup by typing ctontab -l > mycrons.cron. This will save your current list of cron jobs in mycrons.cron.
Then edit the crontab
< crontab -e
This will load the current list of cron jobs in your default editor. (Which is specified by the VISUAL or EDITOR environment variables. Setting this is system dependent. You may be able to set this variable in your .bashrc file.)
Now add a line to start the script:
10 3 * * * /home/dshield/bin/dshield_clean.pl
This will start this program at 03:10 AM each day. Please change the time. Otherwise, we will receive all logs at the same time ;-) . Once you quit your editor, this new crontab will be installed.
Type crontab -l to display the current crontab (i.e., what we just did.)
If you want to change cron parameters, say to make the script execute more (or less) often, edit the crontab using crontab -e and then install it again.
See man cron, man crontab and man crontab -S 5 for more information.
