SSH Gateway: IPTables

Files added:

• /etc/default/iptables
• /etc/init.d/iptables

  mkdir  /var/lib/iptables

update-rc.d:

 -- added s-link:  /etc/init.d/iptables --> /etc/rc2.d/S18iptables

 -- update-rc.d iptables defaults
     -- made /etc/rc2.d/S17iptables

 -- rebooted to test:  iptables started ok!

How to reconfigure IPTables2

Config and usage:

1. edit /root/etc/iptables*
2. Either

            /root/etc/iptables.rules.sekhmet.itservices.sh --restart-ssh-access

   or

            /root/etc/iptables.rules.sekhmet.itservices.sh --restart-total

   as appropriate.
3. N.B. The script iptables.rules.sekhmet.itservices.sh also restarts the fail2ban service (after both --restart-ssh-access and --restart-total) to ensure all is well.
4. Save config into initialisation scripts:

           /etc/init.d/iptables save active

5. Copy (scp) new config to sekhmet.umist.ac.uk/etc for safe-keeping.
