Debian User Forums

I have no immediate security concerns or anything, I'm just curious and thinking out loud. One of the services I host on my personal/home server is a Minecraft Java Edition server. I have it publicly available because a handful of friends also play on it. I created a separate user account specifical...

I ended up just sticking with mdadm+LUKS+EXT4 . It's what I've been using so I know it works and Debian's implementation already checks a lot of the same boxes, even if I'm using multiple different products to do it. I also ended up returning the drives because they came from a third party and were ...

Hi there, I don't have much experience with RAID or ZFS so I can't say much about performance but I think I can answer some of your questions. ZFS handles disk failure a lot better, however, it is not maintenance free. You need to scrub the system regularly (I recommend once a month because it puts...

So I've got three new drives on the way to upgrade my server. The old ones are going to get repurposed or sold. My home server is running headless Debian that I've set up and configured the way I like and what I've been doing is: mdadm (RAID 5) -> LUKS encrypted container -> EXT4 filesystem This has...

I use the UUID in fstab instead of the "/dev/mapper/whatever" name, so that's good to know.

Title pretty much says it all. Right now with mdadm -D /dev/md0, and when reading /etc/mdadm/mdadm.conf , the name of the array is name=adams-server:0 . Is changing the name of the array as simple as editing mdadm.conf and rebooting, or do I need to do something else to actually write that name into...

So, as somebody who isn't a cryptography expert, let me see if I understand something right. I hope y’all don’t mind me trying to educate myself, and would appreciate some high level/layman type feedback so that I can at least have a big picture idea of how the encryption is working, and what is or ...

Could this be an issue with running out of PCIe lanes? Yes it could be. The card in question is not relevant but more likely how the motherboard handles that x16 slot. Look for a block diagram of the motherboard and note the choices. Better motherboards may have pci-e bifurcation settings. Cheaper ...

Debian stable (bullseye). Older hardware; an Alvorix motherboard and an AMD Phenom II x6 1045t CPU. System is acting as a home server/NAS and is headless; no GUI installed. The on-board ethernet is only 100Mbps, so some years ago I installed a PCIeX1 gigabit card. I also just installed a PCIeX1 SATA...

Let's say I've allowed a range of ports and forwarded that same range in my router. Is there a way to specify a firewall rule where that range of ports is only accessible to processes running under a certain username? Like, let's say I have opened port 80 in my firewall, that the user www will use i...

(..) Say, over the entirety of the drive, read the contents of a sector into memory, then overwrite that sector with its own data as if it were new data to "refresh" that information and prevent bit rot with data that isn't accessed very often. Take a full breath and forget about this ide...

Is there a way to "resilver" a drive without data loss in order to prevent bit rot? Not really a concern, just curious and seems like something that would be a good idea every year or two. Say, over the entirety of the drive, read the contents of a sector into memory, then overwrite that s...

I thought I would go ahead and post some photos of what I see under the working and now non-working boot conditions. Here's what I see with a normal boot using 5.10.0-18, leading up to entering my LUKS password. normalboot.jpg Here is what I see if I try to boot with 5.10.0-19. It takes a solid 30 ...

Yeah but then you won't get kernel updates automatically and will have to manually check for and install them.

Update. I just installed the updated kernel on my home server with an AMD Phenom II X6 and it rebooted without issue. I have other PCs in the house but they're all Intel, and my desktop is running an AMD FX 8370, though it's running testing since I use it for gaming. The only computer in the house s...

At grub just go down to "advanced options" and it'll give you a list of kernels that are available. Even with apt autistics autoremove it keeps the most recent old kernel as a fallback for occasions such as this. I did that, I write from the machine in question... I don't want to select k...

It has to do with AMD hardware. I posted about it here: https://forums.debian.net/viewtopic.php?t=153103 I reverted back to the .18 kernel for the while being and removed this meta package linux-image-amd64 so it doesn't update automatically. My home server is AMD, but it's an older AMD Phenom II X...

I saw a post about this in a Facebook group from somebody else, but upon updating my laptop to 5.10.0-19 it no longer boots. 5.10.0-18 still works perfectly fine if I select it in grub. My laptop is a Lenovo IdeaPad 330S with a Ryzen 5 2500U. I'm at work right now so I can't provide error details bu...
