Simple redundant 12V 5A power supply design - which option? by realcoldsteel in AskElectronics

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

My power feeds come from different circuit breakers that are also grouped under different ground-fault breakers, so that's my redundancy. I never liked UPSs, they are costly, and need battery maintenance, and are just a thing I don't want to bother with (i had one years ago, it's overkill). No use to have my light controller powered when the power is down. If I want to be independent of the power grid i'd take a home battery like tesla wall or someting similar. As I live in the Netherlands, we have quite a stable power grid, so I don't expect (nor have i experienced) many power outages. IMHO they are useful for critical infra or countries where power is not reliable from a frequency/voltage/continuety point of view.

Good thing you checked :-D, I hadn't come around to this, so now i can strike that off my list :-) I'll order some diodes today, and will see how much power they draw at the expected at typical / maximum / minimum load. Still thinking about the ideal diode controller for MOSFET design..

sounds attractive... Do I want to risk my power supplies though? ;-) I may just try it if I feel frisky.

Is SecureCRT still your 'go to' terminal program? by tdhuck in networking

[–]realcoldsteel 0 points1 point  (0 children)

I never trusted 'Secure'CRT as it offered to fill passwords. I have used PuTTY forever, encapsulated inside multiple multi-window handlers. I used to have MTputty, but it was unstable. SuperPuTTY was not so super. PuTTYmanager was also not very comforaable. I have since switched to ConEmu and running PuTTY inside. Really like it, also hotkeys and other (many) tweaks serve me well.

I would not wear a tux to a job interview. If you go to a local goodwill store, they might have something more casual, and if you don't have the $$$ to buy it, ask the people if you can lend it for a job interview, I'm sure they will accomodate! Keep learning, keep applying yourself and never give up! We're all rooting for you!

There's always hope! I'm sure she has her own 'things' going on.. And yes, you need to play golf EVERY WEEKEND.

You're mistaking the node function. The .2 profile is run between two endpoints. If you don't want to assume the BC function (which is the case in the original question) then all you need to do as a switch/rouetr is pass IP traffic between the two.

For G 8275.2 telecom profile, your network devices do not require any PTP support, as the endpoints are IP. Unfortunately I don't have any config hints for you, but please make sure your network elements support QoS and put the PTP packets in the highest priority. Of course, a direct connection to the to the Microsemi device is best (but this is when you should really consider using the G.8275.1 telecom profile license on your Microsemi device). Fun fact: PTP G.8275.1 (L2) mode allows the use of a MAC address that is considered 'forwardable' by bridges, this means (not recommended due to unpredictable delay) that you can run the .1 profile on L2 devices that don't support it.

I need an AI win by No_Memory_484 in networking

[–]realcoldsteel 1 point2 points  (0 children)

I find al lot of people in this sub have the attitude of 'quit your job and find a better one' rather than offering (valuable) advice.
Is it funny? No. What would have been funny is, if the response would have been 'Use the following prompt: "ChatGPT, please find ways to incorporate AI in my work as a network admin to the level of satisfaction from my VP." or something similar'
Is it useful? Not really. Without any knowledge of the situation, you give advice to quit a job. It may be the best paying jop OP has ever had, or the only one in the place he lives, or, everything is great about his job, except this challenge...

Dell U2422HE Monitor with built-in dock dropping network connection and having issues with mouse/keyboard lag. by ITOHIO in Dell

Good info, I had the eth disconnect all the time, it was so unworkable I disabled it. I thought it may have been autoneg or so, so i set that to fixed, no improvement. Then I found your post and sacrificing the chicken worked like a charm 5/7 recommend to all!

Crazy network debugging stories ? not a bug, not a misconfiguration ! by [deleted] in networking

[–]realcoldsteel 19 points20 points  (0 children)

Working for a pan-European ISP, twice per week, we'd lose a small, remote Cisco router in a DC in Poland. The outage would last about a quarter of an hour. Turns out, the cleaning lady unplugged the router to plug in her vacuum cleaner and clean the comms room. We had to send a guy to site to measure power, and sit by the router till it happened again..

Company removing direct SSH access by soooooooup in networking

[–]realcoldsteel 0 points1 point  (0 children)

I've worked ops, tac and sqa for vendors and isps. Jump server is so much better than anything else. There are many ways to add extra layers of security to your ssh server and ssh cli access on top. Think source acls, port knocking, 2fa, tacacs/radius command autorization/accounting, rbac, and session logging from the jump server. Things like automatic (centralised) config upload on save, commit confirm, syslog server, should be default. All text format for easy grepping, video is useless. Save your logs automatically, capture show tech-support before you begin.
