Hello all,

I have KMS 6.7 running on an Ubuntu VPS instance at Linode - it's turning out to be a great combination, by the way...

Just curious if you all feel that I should enable IPTables Firewall, or is it rugged enough without it - nothing else is running on the VPS except for KMS.

If I did enable IPTables, I would need to open ports for Web, management, SSH, Pop3 and IMAP.

Thanks in advance for your input!

I would DEFINITELY turn on IPTables. I got started hosting on Linode VPS's before finally having to get my own server.

Without IPTables you are wide open on the Internet.

HoosierMac, thanks so much for taking the time to reply.. Glad to hear of someone else that has had good luck with Linode!

Can I play devil's advocate for a minute, just for learning? let's say I enable IPTables, but i open up HTTP, HTTPS, IMAP, POP3, SSH, and Kerio Management ports.. Aren't those the only things that are listening on that VPS, and if so, wouldn't the net effect be the same w/o IP tables?
Anyhow, just curious for discussion purposes.

Thanks!
Bryan

If you don't enable IPTables, every single port on your Linode is accessible from the Internet. That's a "Bad Thing."

If you enable IPTables, you can use Fail2Ban to read the IPTables log and block hacking attempts as they happen.
