DESCRIPTION

15       fwrestart uses terminal auto-response codes to safely re-start firewall
16       rules over a remote shell session.  It sends a request to your terminal
17       (xterm, for example), which responds  back  automatically.   When  that
18       response  is received, ensuring that fwrestart can communicate with the
19       terminal, fwrestart then issues a command to restart the firewall.   It
20       then tries another request to the terminal, and if that is not received
21       within 5 seconds, a command is run to clear the firewall and an  appro‐
22       priate error is generated.
23
24       The  goal  is  to  be  able to automatically detect when changes to the
25       firewall block the administrative shell session, and to take corrective
26       action.
27
28       By  default  the  commands  used  to restart and clear the firewall are
29       "/sbin/service  iptables  start"  and  "/sbin/service  iptables  stop".
30       These commands can be changed by modifying the values of "fwRestartCmd"
31       and "fwClearCmd" at the beginning of the fwrestart script.

EXAMPLES

36       block the current session:
