Been using a Zyxel NAS-320 device with two WD Red hard drives, real hardware RAID, simple to setup, works straight away with Linux, and was inexpensive. Basic box was about $150.00 / $175.00 not including the drives. Been running non stop for at least two years.

Things may have improved over the years since 10-04, but I've only used dhcp in the router to get me an ipv4 address for the router, everything else is host file based. My /etc/hosts file: ======================================= 127.0.0.1 localhost 192.168.xx.1 router.coyote.den router 192.168.xx.3 coyote.coyote.den coyote 192.168.xx.4 shop.coyote.den shop 192.168.xx.5 lathe.coyote.den lathe 192.168.xx.6 lappy.coyote.den lappy 192.168.xx.10 GO704.coyote.den GO704 ======================================== Identical on all machines And my /etc/resolv.conf from any machine ========================= search this-machines-name nameserver 192.168.xx.1 order host,dns ========================= This one made immutable with a sudo chattr +i specifically to keep network-mangler from mangling it if its still installed. Then you can configure /etc/network/interfaces to look something like this: ====================== # list of interfaces to bring up at boot auto lo eth0 # interface lo iface lo inet loopback address 127.0.0.1 netmask 255.0.0.0 # interface eth0 iface eth0 inet static address 192.168.xx.3 netmask 255.255.255.0 gateway 192.168.xx.1 ======================== Where the last number of the eth0 address is that machine. And if network-mangler is still installed, sudo chattr +i that file too to keep it from being re-written by mangler. In wheezy, N-M can be removed. On all the linux machines. I don't do windows, any flavor, so I can't advise on that. But the last time I setup a neighbors windows machine, that is exactly what I did as he had a router that could NAT, so I made it so. > > On 11/4/2015 8:01 AM, Rick Lair wrote: > > Maybe not the right place to ask, but, regarding the networking, why > > would randomly you not be able to see other network computers?

Can you ping them by name? Can you get their address from an ifconfig report on each machine, then go ping them by address from another machine? The latter, as long as they are all in the same class D address space but you can't ping them by address, I'd say you have hardware problems. > > Rick > > > > On 11/4/2015 8:27 AM, John Thornton wrote: > >> If he is doing that from a Windoze computer you can configure the > >> right click Send To for each machine so it's a one click op to send > >> the file. > >> > >> JT > >> > >> On 11/4/2015 7:16 AM, Rick Lair wrote: > >>> It was an absolute requirement that I got that to work, probably > >>> like yours, we now have multiple machines in the shop running > >>> Linuxcnc, and thumb drives are easy to lose, so I have all the > >>> machines networked together, so the guy in the office that makes > >>> the programs, can drop the finished g code program right into the > >>> nc_files folder in the respective machine, right from his desk. > >>> > >>> > >>> Rick > >>> > >>> On 11/4/2015 8:09 AM, John Thornton wrote: > >>>> Sweet, and it works!

I hope it helps someone: The least expensive version of RAID uses two mirrored drives ( RAID 1 ). Others get a bit more complicated, but they are worth considering if you need larger amounts of storage. There are home NAS available that don't have RAID or mirroring. I would stay away from those, they are just a network attached disk drive. Any drive CAN be used as drives for RAID devices. There are ones that are specially designed for RAID use, like Western Digital RED drives, and there are others from different manufacturers. Backing up using something like CRASHPLAN or better yet, something that specifically supports your NAS device, is great. You can even backup a NAS manually to another NAS or even just a USB attached disk drive. On backups, any backup is good for 'awe shucks' problems (accidently overwrote or deleted a file). But for 'disaster recovery' (your house took a lightning hit and fried the electronics - it happened to me), the 3-2-1 backup scheme helps. 3 separate backups, on 2 different media, and 1 of the off-site. Personally, I use CRASHPLAN and backup machines to on-site USB attached drives and off the the CRASHPLAN data center. -- This is for me and my family, possibly not for your business. If you use CRASHPLAN and you have a good internet connection, you can backup to a computer at another location (like at grandma's house across town, or at the office, or a friends house). CRASHPLAN is not perfect and I am just a user and no ties other than that. It is cross platform compatible from Linux, Windows, and I think Apple (I don't have those). Pretty easy to set up. BTW, there are other great backup programs out there. And 'file sharing' programs really don't count (think Dropbox ... I use it too, but it is a different tool for a different need/use). On any backup, they must be monitored and tested. At least every few months restore a few files to make sure it is doing OK. Being a bit OCD and ADD, daily detail monitoring I knew was best (and fed my OCD), but it drove my ADD crazy! Don't stress over it, but do it regularly. Having software email me 'reports' when things are missed for a few days, it helps me a lot. Oh yes, I am cheap. CRASHPLAN has a 'family plan' for up to 10 machines for unlimited storage to use their central servers for one price. If you have some friends that use it, you can backup to THEIR CRASHPLAN machines for free (this is what you would use to backup to Grandma's or to a work computer. CRASHPLAN is NOT open source, but you can install it for free and give it a try. There are some good open source programs out there, but they tend to take a bit more effort to get set up. I will never claim to be an expert, but I retired from IT after 35 years, the first 20 as a developer, the last 15 as a sysadmin on mainframes, UNIX, and windows systems. The last 10 years was doing backups and disaster recovery principally. I hope this helps a little. Enjoy.

Usually the NAS box like you have listed below will have a processor and one or more NAT devices. Then you can add the hard drives that you like to the box. Some come with drives included. usually the OS on the box is a custom one that is based on Linux. Usually you can remote into the box through a web page that is hosted on the NAS box. I am using a WD MyCloudEX2. I don't know if I would recommend it or not. It needs external cooling as it does not have built in fans so I have it setting on a laptop cooling fan thingy. I also have a better NAS at the farm office but I can't remember what it is off the top of my head right now. It is currently hosing 2 HDDs but can be expanded to 4.
