I'm trying to set up a Windows system so that all multiple logins are tied to the same local user. I want it to be multiple logins so nobody has to share a password and it needs to be effectively the same user so that saved items are easy to find. Other than using GPOs to remap things like documents to be a logcal user at login does anyone know a clean way to go about this? A lead hand signs into the system at the beginning of a shift and then other people use the computer to operate a connected device. So if they save a file another person could have logged in next time they try to open it and our users aren't always the smartest and the more uniform it is for them the better.

I have been getting absolutely hammered with spam via SendGrid (Twilio), and it's largely making it past the spam filters. I've trained on all of them, but they're still not getting a high enough spam score for quarantine. I've lowered the score about as low a it can go without blocking legit mail (and most other spam is correctly caught).

This week alone, I've sent 8 abuse reports to abuse@sendgrid.net. Those plus the ones I sent last week have all gone unacknowledged and unanswered, and there has been no noticeable change in the inbound spam.

I'm to the point where I'm going to just IP block them entirely, but before I do, anyone know of any major companies I may inadvertently prevent from emailing me / my users?

Hi sysadmins, I am thinking of doing a pretty drastic career change. I have 10+ years of experience in chemistry doing bioanalysis and a few years repairing breath alcohol analyzers. I have always considered messing around with electronics, networking, and computers/servers as a hobby and have been using various Linux distros as my main os for almost 20 years.

I have come to see my specialty in my line of work as a dead end. I'm pretty damn good at my job but I feel like automation is going to be taking over very soon, and I'm not that good that I think I'll be in the top 10% that get to stick around and run the automations when the robots finally take over. So I'm considering doing a career change to IT/sysadmin.

What I'd like to know is what should I learn how to do to see if I'll even like moving down this path? What can I set up at home, break, then fix that would give me an idea as to what the sysadmin life is really like?

I'm pretty sure I haven't ever really done any sysadmin type work with my home setups, seeing as I build and set up services I want for myself and at the level I'm willing to put up with. For the most part I can be handed something already implemented and work within that space to keep it going and adjust it to what I want it to do or fit my set up. I can usually find my way through log files and error codes to figure out what the problem is and duckduckgo my way to a fix.

Projects like Arubis use a web based proof of work to slow down and and potential stop not traffic. The idea is that the proof of work makes the client spend some computer resources accessing the page so that it isn't as computationally feasible to abuse public websites.

However, doing this all as a web service seems inefficient since there is always a performance penalty tied to web pages. My idea is what there could a special http protocol addition that would require the client to do a proof of work. Doing it at the browser/scaper level means that it would be Mich more efficient since the developer of the browser could tailor the code to the platform. It would also make it possible for bots to do it which would still allow scrapping but in a way that is less demanding on the server.

I have a SMB share on a computer. It's set to anonymous access, meaning I don't have to enter a password to access the shares. All my PC's at home are Linux so this has served me for many years. I now have a Windows 11 laptop from work that refuses to connect to this device. The message it gives me is you can't access this shared folder because your organization's security policies block unauthenticated guest access

I have tried adding a new share that requires authenticated access, but Windows keeps giving the same error.

I have changed the protocol settings to be higher, but they had no effect. Here is my current config:

#======================= Global Settings =====================================
[global]

	protocol = SMB3_11
	client min protocol = SMB3
	client max protocol = SMB3_11

	workgroup = REDACTED.HOME

	server string = SAMBA

	map to guest = bad user

	hosts allow = 192.168.1. 127.

	printcap name = /etc/printcap
	load printers = no

	log file = /var/log/samba/%m.log

	max log size = 50

	security = user

#============================ Share Definitions ==============================
[smbshare]
   path = /mnt/share
   public = yes
   only guest = yes
   writable = yes
   browseable = yes
   create mask = 0777
   directory mask = 0777
   printable = no
   guest ok = yes

[smbshareauth]
   comment = Authenticated share
   path = /mnt/share
   read only = no
   public = yes

This config still works for my anonymous share on my Linux machine, but (still) not on Windows 11 with the authenticated share. Removing the anonymous share from the config and leaving only the authenticated share does nothing for Windows 11, still same error.

Protocol before was

	protocol = SMB3
	client min protocol = SMB2
	client max protocol = SMB3

I tried to connect to \\192.168.1.5\smbshareauth but that gives the above error. Help is greatly appreciated!

From today until March 15, 2026, the maximum lifetime for a TLS certificate is 398 days.

As of March 15, 2026, the maximum lifetime for a TLS certificate will be 200 days.

As of March 15, 2027, the maximum lifetime for a TLS certificate will be 100 days.

As of March 15, 2029, the maximum lifetime for a TLS certificate will be 47 days.

What's everyone's opinion on this? I think from a security standpoint their reasoning is valid and in many cases it's very easy to automate the renewal with ACME or something else. But there's likely gonna be legacy stuff still around in 2029 that won't be easy to automate.

I need to replace a bunch of ancient Cisco stuff. Also looking at other brands like Dell, Juniper and Extreme

I posted last week about building a NAS, and on friday I saw that the Jonsbo N4 case I had been eyeing for a while was in stock at a good price.

So now I am looking for a motherboard to base my system on, which seems to be a bit difficult.

I need an mATX or ITX board that can handle six SATA drives and also have an NVME slot for a boot drive.

Performance, I value power efficiency more than super high performance, and am on the fence between Open Media Vault or TrueNAS, I like the familiarity of Linux, but I do value the features of ZFS.

If I end up on TrueNAS I may run a VM in the hypervisor from time to time, mostly just for testing.

The NAS will not be an HTPC, but will serve media through SMB and possibly NFS later.

Cooling could be a bit of an issue as the case does not have a lot of space for a cooler

I am sorry if this the wrong community to ask in, while I have been on Lemmy for more than a year now, I am still learning my way around, and this seems like a relatively active community in a relevant area.

Right, on to my questions!

I am planning to build a NAS over the summer, at the moment all of my personal photos are stored on a single mechanical 2TB Seagate drive that is about 4 years old.

I have other media on another drive that is older but larger, all in all I expect that I have about 8TB of data that I care about.

I am working as a 365 admin, and have been the main Linux admin at my last place of work, I am also a hobby photographer in my spare time.

Currently, I am looking at using either the N4, the N3 or the N5 from Jonsbo, the N4 is a beautiful case!

I am thinking of running four 6TB drives in a softraid like this:

Linux > MDAM (raid 5) > LVM > ext4

My thinking is that I will probably need to migrate to new drives every X years or so, and with the LVM, I can just add a new external (larger) drive to the VG, and move the LV from the old drives to the external drive, remove the old raid drives from the VG, put in new drives, setup MDAM, add the raid to the VG and move the LV back to the raid.

Am I overthinking this? this NAS will be my main media machine and will probably see a decent ammount of use over the years.

I have thought about setting up OpenMediaVault or TrueNAS as the OS, but having never run them, I wonder if they will be as flexible as I want them to be.

I am currently considering just running Debian and setting this up from the terminal, but I am not a super fan of SMB settings in the terminal, I did consider using cockpit as a web admin tool once it is setup to monitor the system, can I do the SMB config from that?

I am apprehensive about a manual SMB config, as the last time I did it, it was a weird mess for the team who had to use it...

I am more familiar with AMD hardware over Intel, and I am looking at the old AM4 plattfrom, but what I don't know is how much power a homebuilt NAS will use in standby or when active.

After decades of using the standard mouse cursor in Windows, and loosing track of it more and more as displays and resolutions grew, I have finally changed it to black and increased the size of it one step.

I find it so much easier to locate my cursor across my 1440p monitors, it is just clearer what is going on.

In the office I use a turqoice cursor, and at home I use the black cursor, it is a slight annoyance to get used to it, but wow, it is fantastic!

The first email of my day was sent to our head of HR asking what their hiring projections were for the next 6 months-1 year (usually I just get 1-2 months advanced notice) so I can shore up our tech stock

From a simple KeePass database to enterprise credential management solutions—what’s your setup at work?

Today I announced on the company wide Slack channel that, effectively immediately, we were rolling back to Windows XP. There were cheers! and then a lot of disappointment when I said it was just April fools Lmao

I was gifted a R720xd by work (yay!) and want to install a spare 3060 I have. Does any one know of a power cable and advice? Do I hook the power to the riser, the card, both?
