comment How to start with IPv6 subnetting on linux gateway
@MichaelHampton ah ok. i thought i heard somewhere it was a security consideration, rather than an address usage one. /64 across the board does make things simpler.

comment How to start with IPv6 subnetting on linux gateway
yeah, i think using a /64 on every /24 is a pretty common way to go, as it essentially doesn't change the subnet layout, just makes them bigger. I've not deployed ipv6 yet but i think you'll also want a /64 on every ipv4 subnet that's >24 && < 30. For point to point links people seem to suggest a /126 (or /127 on recent gear)

comment Reinstalling linux server
actually you can do this, i saw a senior admin do it to reinstall remote shop systems to get from centos 5 to 6 (and it didnt involve just altering the repos used). Highly not recommended though.

comment OpenVPN 63 max clients limit?
Glueon is right, but to elaborate - this is because openvpn in it's default mode puts each client into its own subnet which has 4 ips. 1 for the server, 1 for the client, one for the network address and one for the broadcast. With 255 available you get ~63 clients max. It is possible with openvpn's 'topology subnet' server setting to put all clients into the same subnet which would let you have 253 clients on a single /24 subnet, but this isn't the default, nor recommended. It also means clients may be able to intercommunicate without firewall intervention by yourself.

As of may 20th, S3 now supports life cycle and versioning together, so that may be an easier solution. aws.amazon.com/about-aws/whats-new/2014/05/20/…

comment Data backup on AWS
if you need minutes for restore, why are you backing up online at all ? Offsite physical backups rotated out would seem more logical ?
