This isn't helped by my solving this once every couple of years and promptly forgetting until it breaks again. Ended up stumbling into a solution. It looks like the issue had something to do with my trying to do the two mounted USB HDDs in a single share. Making separate shares on the host for each and separate mounts for each on the client seems to have resolved the issue, but I'm at a loss as to why. Gift horse, mouth. iirc Samba does this fine though, but I'll need to test that out next. Edit- And now my containers don’t want to work when referencing the NFS directories. Sigh.

admiraldennis posted:The ol' Cyberpower UPS on my NAS PC is reaching EOL. Looking to replace it. If it gives you any indication, NEC stipulates for residential construction a maximum distance between outlets (IIRC, 6 ft) because so many loving fires are caused by using extension cords / similar (to be fair though, a lot of these are idiots running space heaters continuously off dollar store cords). If you're disciplined and put a surge protector in front of your UPS and tape up every other outlet on the surge suppressor, it's likely "fine", but personally I'd trust the UL-listed in-wall outlet to carry high current continuously for 10+ years vs. a power strip that you're "supposed" to toss out more frequently because it's got a cheap rear end MOV (most of them) that loses effectiveness over time if it's exposed to over-voltage conditions. That breaker up-stream is supposed to have your back. Realistically though I doubt you would have any issues what you proposed.

The steps I took more or less set it up that way, but some other weirdness was the root cause. I ended up just mounting the drives to the server directly. While that did solve docker’s hang ups I now have a mysterious folder being created at boot that lives in the same location as the now locally mounted drives and appears to have the contents of one of the mounts. It’s the damnest thing, but I’m just going to leave it alone since it’s not hurting anything.

I posted in here a couple times spitballing NAS ideas but never committed to anything. Now all I have is free time, so I figured I'd revisit it. I've got a dozen old SAS drives that have been collecting dust in a closet. Old like 2015-ish. Mostly 250 or 300 GB capacity, mostly 3.5" with a few 2.5". I want to make a NAS out of them since they haven't been used much and I'm hurting for some storage space at home. Are there enclosures I could order where I could stick a few of these drives in and get it working? I'm thinking I could use at least some of the drives in a RAID setup and then keep a few as backup in case failures happen. I'm fine with needing to do some configuration to get things working properly.

I would personally be hesitant to do this in a scenario where neither drive bays nor power are free. None of the consumer-ready enclosures are going to be ready for SAS, and the products that were aimed at enterprises originally are going to be power hungry and loud. A two-drive solution with a couple of 8TB or 10TB disks in RAID1 would potentially be cheaper than just trying to get all of those drives connected. If you just want to do it as a project, the most labor-involved way (and the one most likely to avoid loud server fans) would be an external SAS controller in the system you're plugging this into, an external SAS cable, an external/internal SAS adapter card, a SAS breakout board, and appropriate SAS cabling from there to connect to your drives. You can stick most of that in whatever case you want with a power supply.

Rexxed posted:Time to update freenas. Looks like I have ~1.5GB of RAM in my N40L, FreeNAS 11.4 wants 8GB. Is 16GB overkill? (Looks like it's $60 vs $40 so unless it's completely useless, it makes sense to me...) This should be fun, too, because FreeNAS has been running since 2012 on a thumb drive. I think I'll probably swap that out while I'm in there to avoid that failing next. Edit: Looks like FreeNAS recommends "more is better", so 16GB is probably worth it. They recommend ECC, and this wiki on HP N40L says no registered ... which leads to one result ($55, refurbished) on newegg. That seems iffy. Would I be better off:

Krakkles posted:Yeah, you're right. Thank you. 16GB is not excessive especially if you get into running applications/jails on your fileserver too. https://n40l.fandom.com/wiki/Memory you probably need a 2x8 GB kit, not just a single 16GB stick. I don't see anyone else confirming single 16GB sticks as working properly. this is where I'd start: https://pcpartpicker.com/products/memory/#E=1&sort=ppgb&U=3&Z=8192001,16384002&t=11 it looks like at this point none of the first-party stores (adorama, newegg, sold by amazon, etc) still carry anything that old but there's nothing wrong with the third party vendors if their reviews are OK.

I installed the bios hack linked to on the n40l wiki to enable full speed eSATA and went from 8gb to 16GB. I picked up the samsung ECC memory on ebay for $70 for 3 sticks of 8GB (used the spare in a C204 server board). I honestly think ebay is the way to go for ECC memory if you don't mind spending a little time testing it. Here's some for ~$32 a stick: https://www.ebay.com/itm/For-Samsung-8GB-2RX8-PC3-10600E-DDR3-1333Mhz-CL9-Desktop-ECC-Memory-RAM-UDIMM-5/254413505994 I can't speak for that seller specifically being good, but buying used seems like the way to go.

Funny enough, I instantly wished this wasn't the case. Picked up a cheap 8TB SAS drive on eBay since I'm out of spares. Arrived today, but when I picked it up, I got the ever so un-fun sensation of a drive sliding around in cardboard. Seller used those plastic end caps, but in a box way too big so there was nothing holding them on. USB SAS adapters apparently exist, but they're hellishly expensive. I'm still going to test the drive before I return it, but that means a minor road trip and dealing with pandemic protocol. It was literally just shipped across town so maybe there's hope.

You know, it used to be that I wouldn't ever touch a Seagate drive, having had a number of them die in very short order, circa.... I want to say, 2005ish. I used almost exclusive Maxtors, and then WDs when Maxtor got bought out, but now? Man, WD is starting to give me a reason to reconsider the Seagate fatwa.

Is it a terrible idea to open a random SSH port to the internet to allow my family's computers to backup to it via Duplicati/some other backup client? I have gobs of storage laying around on a server of mine and would like to get my family's data protected without them getting looped into some monthly pay service. My security logic is: Use a non-standard port Data would be encrypted client side SSH user would be locked into a single directory and be non-root and likely not even have a shell ....? profit

cr0y posted:Ya also that, one thing I never understood is why are public keys better than passwords? Assuming it's a good password aren't they cryptographically equivalent? A long password can, indeed, have a higher cryptographic strength than a short / weak certificate. Thing is, unless you're using a password manager to generate long, complex, random passwords, basically any password a human is capable of remembering is hilariously weak by comparison. If it's for family members (whom we will assume are not Security Engineers or other people unusually interested in their data's protection), anything they can bother to remember is also very likely to be reused, or reused with slight modification, on other accounts, massively increasing the risk of compromise. From the other end, while many attackers are more than happy to sit there and pound away at anything they find that will let them attempt to submit passwords, basically none are going to bother generating a billion certs to submit on the incredibly unlikely chance that they manage to duplicate one. They see password login is disabled and gently caress off to the next guy with an open port. I mean, in the end, is it likely that anyone is going to really care enough to try to hack your family server? Probably not. But when you can set up a certificate that will mean they don't have to remember anything and eliminates reuse concerns, why not? It's super easy to do, after all.

That's really good reasoning, and no I am not dumb enough to let my family pick any of the passwords for SSH or the client side crypto. I'd be managing the setup, so ya I should probably just do certs. I am still in the pondering phase, anything else I might want to consider other than SSH? It just seemed like the least hassle, spin up a VM, give it storage from my array and isolate it as much as I can from anything else on my network since I don't want to make my family members end points on my VPN. cr0y fucked around with this message at 05:05 on Sep 11, 2020 |

Ssh is the gold standard on the internet. Passwords are sent in plaintext across the pre-encrypted wire. Keys are never sent across the wire. Why tell the server your password when you can tell the server the signature of the nonce they send over encrypted with your public key? (my recollection of the process is vague at best.) Remember you tell every website your password every time you login. Ew. Do not leave password authentication enabled. Disable root login. In fact only allow your one user to login. Verify that user does not have a password, does not have sudo access, is not in the wheel group, and is chroot'd into their own little prison. Fail2ban is great and should be used. I wouldn't bother with alternate ports. Want to go further? Ssh supports key CA's for issuing them, and encoding the exact command a key is allowed to run. "ssh -i backup.key user@host" is all you need to do then. H110Hawk fucked around with this message at 05:54 on Sep 11, 2020 |

Passwords are transmitted in plaintext only when the client/server handshake is done and the encrypted pipe has been set up. People sniffing the network would see normal encrypted traffic. I am only pointing it out so people don't think SSH does the same stuff like telnet where everything is plaintext.

Does anyone have any suggestions for a non-raid compatible SAS or Sata controller that supports PCI-e x4? I was set on buying a 9207-8i or a consolation h310 but they're both x8 cards and I only have 1 x4 slot on my board. Probably be hooking up 3 drives for now (all spinners), but I'd really like something that supports 8 like the 9207-8i

It looks like they don't really make SAS controllers at x4, and only a few SATA cards at x4 and those are only two slots. Is your x4 an open slot? If it is you can slot in an x8 card, it'll just have half the lanes available

The LSI SAS2008 is the chipset that runs like every single SAS2 card from 2008-2013 while it was relevant. Also remember that 3 drives will connect to a single SFF8087 on the card, and if you're feeling really bold (well you don't really have any more room on that motherboard [without doing the janky mining card adapters]), you can run 8 drives off that single card, and if you instead plugged both SFF8087s into a SAS expander you'd end up with 24 drives available through one SAS controller

Also just to make it clear, other than port differences (external versus internal/positioning on the card) and firmware, there's no difference between the perc h310 and any of the LSI SAS 92xx-yy cards, so it kinda boils to whichever is cheapest (and if you don't feel like flashing the IT firmware whichever is cheapest and pre-flashed) (i'm rusty on my SAS cards i haven't picked one in a while so correct me if i'm wrong)

Also this is when I'd jump in with another recommendation: if you ever plan on buying SAS drives (benefits: cheaper for a given size, cons: can't be spun down if thats something you care about) getting SFF8087 to SFF8482 cables is better than 8087 to SATA, as SAS connectors will happily plug into SATA drives, but not the other way around.
