Hi Daniel,

Thanks for your comments and you raise a good point. I'll look to adding 
a comment to address that issue.

I guess the best solution would be to develop and test your script 
locally before uploading and deploying on a remote server. 
Alternatively, if you must test remotely, setting up a cronjob to 
deactivate the firewall after 5 mins is a popular approach to prevent 
locking yourself out of your machine (if anyone on the list has any 
thoughts about this, it would be appreciated??)

For some reason your mail never reached the centos-docs mailing list 
despite being copied (maybe you're not subscribed to that list?), so 
I've copied this reply to the list for reference.
