If you need to flush your firewall iptables rules, do not do a direct `iptables --flush` from a remote machine if the default policy is set to DROP packets, you will lock yourself out.
Run the below script instead:
#!/bin/bash
# flushIptables.sh
/sbin/iptables -P INPUT ACCEPT
/sbin/iptables -P OUTPUT ACCEPT
/sbin/iptables -F or set the default policy to ACCEPT before flushing.
To find the default policy:
# iptables -L -n | grep policyBookmark/Search this post with
