I'm not familiar with that error. Can you post the whole error? Or a screenshot?

comment L2TP VPN Connection on Debian Squeeze
To answer your questions @Lashae; 1) It depends on what you mean by simple. There aren't a lot of opensource VPN clients out there that guess at all the possible configurations needed. openswan w/ xl2tp is one of your options. You could use OpenVPN's --script-security with a config file, but you'll run into the same technicalities as openswan w/ xl2tp; you need to know all the parameters. 2) There isn't a lot of documentation available on this, but someone asked a similar question on serverfault before: serverfault.com/a/459900/161412

When you say L2TP, do you mean L2TP over IPSec?

comment How can I limit server bandwidth per IP
Doable, yes. Easy? No. How much (which) of the infrastructure is owned/managed by you and how much (which) of the infrastructure is owned/managed by a 3rd party hosting group?

comment RAID 6 - any write amplification in 4-drive RAID?
I agree; the internal algorithms are designed to use least used bits/sectors first. However, this is not based on how much data you write. This is based on how much data is overwritten, which happens when you delete or overwrite; not how much data you have. If I have a 250GB SSD, and I can only fill it with 250GB of data; trying to fill it with 300GB of data is impossible. If I had a 250GB SSD, and I filled it with 200GB of data, then deleted it, then filled it again with 200GB of data, then yes, there will be roughly 150GB of bits that will be overwritten.

comment RAID 6 - any write amplification in 4-drive RAID?
The data you provided in your question only went over how much data your system had written, but didn't include how much was being over-written. That's the key indicator for determining lifespan of an SSD. As for how the data gets striped, yes, your original assumption is mostly correct; the varying factor is the number of drives in RAID6 vs RAID1.

comment centos doesn't reply to icmp request
So... you don't have a firewall on your server... a server that has public facing NICs?

Do you have ICMP allowed in your iptables?

comment Windows Server 2008 access backup data partition
Only use templateid if you're using a template. Otherwise, build your script specifically for what you want to back up and identify where you want it backed up to. You need to run the script as an admin. See this for reference: technet.microsoft.com/en-us/magazine/dd767786.aspx

comment Windows Server 2008 access backup data partition
If that's the whole script being used to backup your system, then it's backing up to VSS. technet.microsoft.com/en-us/library/Cc742083.aspx Since that's the case, you can migrate the VSS by following the link I provided above. See this reference: technet.microsoft.com/en-us/library/Cc742083.aspx

comment File shows up when I do a listing of my current working directory but says it does not exist if I try to do anything with it
are you referencing the right directory or executing the command from the right directory? rm /file/location/ucm.txt is not the same as rm ucm.txt

comment Multiple servers Rsync into one NAS simultaneaus
Your limiting factor is going to be your branch stores' upload bandwidth. At 1-2Mbit/s, you're going to see maybe, 125KB/s uploads. Based on math, 51200MB * 1024 = 52428800KB / 125KB/s = 419430s / 60s = 6990m / 60m = 116hrs / 24hrs = ~5days. It'd almost be faster to put a copy of all your data onto hard drives and have it shipped to your HQ, then have the data copied to your NAS. You need to increase your branch sites bandwidth or reduce the amount of data you need to transmit.

Unless I can see the script, I can't really tell you anything more. You might just have to write it all down? It shouldn't be more than 1 or 2 lines of code.
