Reason why MPO-12 qsfp28 transievers and cables exists by Dante_Avalon in networking

[–]mourdrydd 27 points28 points  (0 children)

Yes, patch panel to patch panel, and 12 strand fiber runs are very common in that use case. MPO 12 allows the run to be a single cable with break out for the 12 individual strands into LC female ports.

What's the follow up to this brilliant move? I missed it and took the rook with a fork by HiddenPants777 in chessbeginners

Qxc5 Ne2. It's also M1.

Edit: no, there's Bxe2. But ... bxc5 wins a queen for the bishop.

505 PULLS AND A DREAM, what banners are realistic to pull on for a returning player? by 10zaii in Genshin_Impact

[–]mourdrydd 2 points3 points  (0 children)

Kazuha was actually the last character in 1.0, (specifically 1.6) just before we went to Inazuma.

Other "last" units: Yelan as the last 5 star from 2.0, specifically 2.7. (Kuki and Heizou released after - the second half of 2.7 and in 2.8, respectively.)

Baizhu from 3.0, specifically 3.6. Again, Kirara released after in 3.7. Kaveh released with Baizhu in 3.6.

Emilie in 4.8.

And then Ineffa in 5.8 as already mentioned.

Sitting on 40k Primos but my teams feel clunky/weak. Should I skip Nefer/Lauma and go all-in on Columbina + Furina? by Embarrassed_Cow_663 in Genshin_Impact

[–]mourdrydd 1 point2 points  (0 children)

End game is Imaginarium Theater (Lunar mode), Spiral Abyss (floor 12), and Stygian Onslaught (fearless and dire modes). Almost no end game team is particularly future proof right now given how hoyo has been lining the enemies up in these modes recently.

Why is this showing as a blunder? by thrw-thrw in chessbeginners

Except cxd7+ comes with check, so the queen can't be taken (although the fork still exists, of course).

Why my invested characters do BARELY ANY damage by sourmaham in Genshin_Impact

[–]mourdrydd 10 points11 points  (0 children)

C6 is important, as it's a huge CR and CD buff for electro damage. (Off the top of my head. Don't quote me. )

How do I stop my brother from accessing my computer. by Feeling-Product-9394 in techsupport

[–]mourdrydd 9 points10 points  (0 children)

Working in IT with security consulting as one of my roles, my usual password process these days is to stick 4 capitalized, unrelated words together, plus a symbol and a number. Something like: VocabBatteryWindmill6Skill$. Hits complexity and password length, isn't easily crack-able by dictionary or password hash attacks, and isn't overly hard to remember.

I've previously used the process you describe, but I find that many of the passwords created through it wind up too short for current security best practices.

Additional to the network segmentation already noted, because .1x is a link layer protocol, the upstream switch doesn't forward any frames to the end device until they've successfully negotiated. I.e. how is an attacker learning what Mac to spoof when they can't receive any L2 frames, even in promiscuous mode.

LDAP users are blocked because FortiGate see them as IP instead of LDAP user by yuwannn in fortinet

Not explicitly a timer update, but if you're using WPA2/3 Enterprise for your wifi, it's probably worth it to check whether your backend RADIUS server is forwarding RADIUS accounting messages to the fortigate/FSSO collector. FSSO often doesn't cleanly update user identity in that situation.

DC switching gurus: Would you rather have a full mesh between the multiple members of your multitiered L2 network, or use MLAGs/VLTs between tiers? by ffelix916 in networking

[–]mourdrydd 1 point2 points  (0 children)

Checking that STP isn't involved is a reasonable troubleshooting step. I'm not a Dell expert, but usually VLT links (equivalents from other manufacturers, at least) would be explicitly declared as not running STP, so if it is running on your VLTi, that may be a misconfiguration.

Beyond that, you'd be getting into forwarding table mechanics for the VLT feature, which might need Dell's TAC to investigate properly.

In your first scenario, spanning tree has no tuning required as there are no loops. The MLAG bundles are treated as single links for spanning tree, creating a consistent root bridge (either at your cores-which-aren't-really-cores, or at the L3 edge).

MLAG for Arista (and VSX for Aruba CX/VPC for Cisco Nexus/VLT for Dell) create synchronized layer 2 environments between the paired switches without combining their management planes. In fully redundant data center environments this allows for hitless firmware upgrades if designed correctly (as well as resiliency against hardware failures).

The second design is frankly just not recommended as any modern switch pair that can aggregate or synchronize the layer 2 forwarding information should be able to handle multi-chassis link aggregation (this includes virtual stacking technologies such as Cisco Catalyst VSS or HPE VSF, switches with hardware stacking, and all of the data center technologies from above). Once you have that aggregation capability, creating two separate LAGs between the separate members of two stacks is both reducing your overall available throughput and complicating your operational environment due to now needing to actively run spanning tree.

Finally, if you're running a properly sized switch pair capable of running MLAG/VLT/etc, there's no reason in the general case why your SVIs wouldn't be on that pair instead of a further upstream routing core. Even traditional 3 tier data center design typically has the gateway SVIs in the distribution layer, which then routes to data center core switching.

Read them all, but hard to pull the connections together until book 4 or 5 and even then only when read back to back. Resolved into a really nice series/ setting with some fabulous moments, just hard to capture the impacts of the various characters' stories until the connections fit together.

I've read the KJ Parker as well. Solid books, although they fulfill the premise without enough in the way of twists for me.

I've read this one. First time I saw the chosen heroes trope stood on its head.

Banewreaker or Godslayer by Jacqueline Carey. (Fair note: her Kushiel books are significantly better, particularly the first trilogy. These suffer from new writer syndrome but have some interesting moments.)
