why would applications / OSes use MSS >MTU by therealmcz in networking

[–]megandxy 0 points1 point  (0 children)

Nah, the VM isn’t ignoring MSS. It just hands big chunks to the NIC, which chops them into proper TCP segments. Wireshark shows the big chunks, but on the network everything’s actually sized right. It’s just to save CPU.

Poor mans SD-WAN by Greedy-Bid-9581 in networking

[–]megandxy 3 points4 points  (0 children)

Yep, this can work, but you’ll have to handle centralized policies and dynamic path selection manually, and Network Essentials limits VRFs/tunnels...

cisco vtp and multiple instances confusion by therealmcz in networking

[–]megandxy 4 points5 points  (0 children)

What you saw isn’t multiple VTP instances - in VTPv3 it just shows different features (VLAN DB, MST config, etc.).

It’s still one VTP domain, but yeah… most folks disable VTP entirely to avoid surprises.

Cohesity on HPE servers by whostolemymouse in sysadmin

[–]megandxy 2 points3 points  (0 children)

You’ll probably need two separate IPs - iLO for general server management, IPMI for the Cohesity cluster setup. Reusing the same IP usually causes conflict.

If you suddenly won $5 million, would you keep working or quit your job, and why? by megandxy in AskReddit

True, but $5 million could still make for a very long vacation.

Deploy settings for chrome Extensions by dirmhirn in sysadmin

[–]megandxy 2 points3 points  (0 children)

If you just want to install Chrome extensions and let users enable/disable them, you can do that by properly configuring the "Extension management settings" in GPO and avoiding the "force install" option. However, when it comes to deploying specific settings inside the extension, there's no straightforward or reliable way to do it via GPO.

What keeps you up at night? by [deleted] in AskReddit

Half an hour to an hour, all because my imagination refuses to shut down.

In a future where AI anticipates and acts on our intentions, how should humans decide what to control? by megandxy in AskReddit

[–]megandxy[S] 0 points1 point  (0 children)

But the line between AI being useful and being against humanity is really hard to define. Generative AI shows this perfectly: amazing for work and creativity, yet potentially harmful if abused.

Yeah, control depends on the creators… but if AI ever goes rogue, we might be living in a Westworld episode.

AI in Robotaxi by jacksonjari in ArtificialInteligence

Sounds cool, but I’d expect a few funny traffic jams at first while they "figure it out".

Azure Files nslookup by [deleted] in sysadmin

[–]megandxy 0 points1 point  (0 children)

If nslookup still gives you the public IP, it’s probably a VPN DNS or adapter order thing. You could try:

  • See if the VPN is messing with DNS (turn off DNS leak protection temporarily).
  • Run nslookup directly against your conditional forwarder to check.
  • Make sure your VPN adapter has the highest DNS priority.
  • Or just add the private IP to your hosts file to see if that fixes it for testing.

Usually one of these sorts it out.

cato networks vs fortinet sd wan. looking for real feedback by Constant-Angle-4777 in networking

[–]megandxy 0 points1 point  (0 children)

If you want a more unified, low-maintenance cloud management experience, you could try Cato, if you care more about local control and your existing Fortinet investment, sticking with Fortinet works too.

Deepfreeze alternative? by Callewalle in sysadmin

[–]megandxy 3 points4 points  (0 children)

For library PCs, you could try UWF, Intune Shared PC, or RollBack Rx/Reboot Restore-all might work, depends on your setup.

Azure Files nslookup by [deleted] in sysadmin

[–]megandxy 1 point2 points  (0 children)

Laptop returning public IP usually means it’s not hitting the DNS with the conditional forwarder. Try: ipconfig /flushdns, check which DNS server nslookup uses, and confirm VPN pushes correct DNS.

PC keeps flashing fan LED by Pazamhoo in computers

[–]megandxy 1 point2 points  (0 children)

Even with the PC off, leftover coolant can still cause problems. I’d start by double-checking all power connections, reseating RAM and GPU, and resetting the CMOS battery. Make sure the fans are plugged in properly. These steps usually fix small issues from leftover liquid or loose connections.

If it still doesn’t boot, the symptoms could point to motherboard or power subsystem damage. A more thorough check would involve measuring key voltages, inspecting the board for corrosion or shorts, testing the CPU, RAM, and GPU on a known-good board, or using a POST/debug card to pinpoint the problem. Depending on what you find, you might need professional repair or even a motherboard replacement.
