@devonblzx Error Correction codes (e.g Reed-Solomon) can also be used. I dont know much about them though. There is probably more (possibly even patents - lots of RAID6 patents exist). This is not my area of expertise.

It is worth noting that RAID6 is not standardised. It can be defined as "Any form of RAID that can continue to execute read and write requests to all of a RAID array's virtual disks in the presence of any two concurrent disk failures.". Implementation is separate from this (dual parity is a...

Yes there is a mistake in my post, I got confused in regards to Key Exchange. There is no need for it (keys are transferred out of band), which makes it possible to use asymmetric public key encryption. I might consider making a flag for the script to support it if I can do it without adding...

There is a few points I want to point out in this regard. Dave is correct with the following points: WHMCS does not cancel Paypal subscriptions Paypal subscriptions are a nightmare to manage from the Paypal UI from the merchants perspective (and also from the clients!) If an account with...

Yes, Dont use this for backing up your email server. I don't know of many "enterprises" keeping their primary mail server on a server with shared responsibilities (i.e web/database) requiring backup. Generally speaking its one of the first thing you seperate out for security of private...

@willie Let me try and explain this. 1) In all cases when performing asymmetric encryption a key to use as a "private key" is required. It can be either a "private key" or (most of the time) a "public key", that is to say a public key used as a private key. The names are just semantics based on...

Gotta admit I never really I learnt it until I had to produce my first scripts to do certain things. Once I got over the hurdle of the pipes & filters style it all sorta seemed to make sense. Off the top of my head. A few things to remember: Treat everything as a string unless you have...

Cam we please have back the recent topics in the sidebar? Its a great way to catch up in the morning and ensure that nothing is missed. VPSB feels so quiet without it :(

@willie, are you concerned regarding the security of your restoration server? Personally I dont see the use-case for public key encryption. Just so we are clear public key encryption would work as follows: Backup Server: Has Private Key, can write and read backups Restoration Server / During...

A good way to get in the good books when asking to do something that may be considered borderline (i.e usage of more resources in a burst etc) is to mention that you read the ToS. It shows you are serious, and that you are putting in effort.

In spam circles.

Should you be taking backups of more things than you currently are? Well now there is no excuse. Just use this 50 odd line script and receive your encrypted backups attached via email. Download: The script is available at Github - https://github.com/splitice/encrypted-email-backup Features...

IPv6 We have the technical capability of doing IPv6 mitigation and three of our locations. We currently however do not offer it, we just don't have enough commit to offer it standalone with any serious volume - primarily due to the need for such filtering being so small. IPv6 is barely used...

@bigcat Obvious troll is obvious? Given that the first instruction to anyone hoping to achieve PCI compliance is to Install and keep updated a firewall between the public network and the payment card data. I guess so. What you describe would meet none of the intended protection aims. Having...

After the GVH "hack" where Gov IDs were leaked I started working on this tutorial. It details a similar system to what we use to store client SSL certificates for the interface and deployment system. The system described is complex to setup, but does not compromise in security. If you store...

Personally, I think its a bit high for a used server.

About 10% of our business (slightly more) over the previous year came through BTC (via Bitpay). As we use Bitpay (AUD conversion) fluctuations don't bother us. Personally I think its a good gateway to have, gets more use than Payza (who we maintain as a backup gateway primarily for Visa/Master...

I predict 2018-2020 as the IPv6 year, perhaps by then dual stack sites will be normal. I also have confidence that VPSB will be around in 3-5 years to verify this claim.

Layer 7 DDoS attacks will become more popular as Layer 4 DDoS protection becomes more popular and prevalent. I will also predict: - A new massively popular vulnrability will be found to be insecure and usable for massive amplification attacks. There is just too much software, both legacy and...

@blergh that seems like more of an argument for Pure IPSec tunnels than against it. Transmission in plaintext for security critical data should be avoided. GRE & IP-in-IP (the standard for tunneling protocols) are un-encrypted unless IPSec transport is used, an IPSec Tunnel is another method...
