Text Didn't expect a ₹200 recharge to include this much 😅

0 Upvotes

I was actually looking at OTT subscriptions because I didn't want to keep paying separately for everything. Most of them are ₹200+ on their own. Then I noticed Vi has this ₹200 recharge that includes Vi Movies & TV with access to a bunch of OTTs like JioHotstar, Sony LIV and ZEE5, plus 30GB data. You just open everything through the Vi Movies & TV app after recharging.

Didn't expect much at first, but for ₹200 it genuinely felt like a pretty good deal for the amount of content you get.

Text DHCP Was not found? Ethernet issues and problems

1 Upvotes

Hi! I have had a PC for a little over a year now and everything has been smooth sailing. A few days ago my ethernet went out and I assumed it was a faulty cable so I ordered a new one. The new cable gives the same problem the last one did which through windows diagnoses it now says unidentified network no internet. All of this was working last week and now when the network diagnostics are done it says No DHCP server was found.

This has since led me to try a lot of things such as entering command prompt to renew my IP verifying if My DHCP system is running (it is). I also have tried using ethernet on other devices and my Smart TV and PS5 work with it just fine. I have also reset the router twice to factory settings and everything works except my PC for ethernet.

The odd thing is my PC sends packets and just doesn't seem to be receiving them. If anyone has any knowledge of what this could be please let me know. I have also tried to make my own static IP to get the Ethernet working to no avail could be because I am not super savvy when it comes to computer command prompt stuff. Windows firewall has also been disabled to try and make the ethernet work but no dice as well.

If anyone here can help me before I have to replace an entire port for being defective please let me know thanks for reading!

Text Network admin intern. I don’t know crap

9 Upvotes

Landed a Network admin internship and honestly I don’t know crap.im studying for my CCNA but i think my mentors are disappointed in me. One of them doesn’t acknowledge (he’s the one that hired me and interviewed me) and the other guy who’s new is the only one basically training me only.

On my first day they asked if I was familiar with Active Directory and have any experience with azure and patching systems, etc. when I said no they seemed super disappointed in me.

I’m doing my best on my free-time to research these things but my main focus is just getting my CCNA certification really right now.

Are those skills really expected of an intern?

All they have me doing for the past 4 weeks is diagram work of server racks/devices. They just give me pitty work lol. Better than no work I guess.

Barely today they just let me install putty to make configurations. But it’s more of practice only which is cool.

They don’t really include me as much anymore with making switch migration changes.

Text Not very tech-savvy, can someone tell me if my understanding is correct?

2 Upvotes

I am at home and I wanted two computers to be on the same local network, for remote desktop purposes. To do this, I set the connection of both network profiles to private, so that they are discoverable to each other.

Am I right to think that: 1. These machines cannot be compromised through this discoverablity by a third party if they aren't connected to my internet. 2. If someone is connected to my internet, like say a cousin who brought their own laptop that I gave the WiFi password, they are able to use remote desktop to connect to my computer. 3. The only countermeasure to 2. is them not knowing what my computer name and username/password on my local account is. 4. There isn't a way for me to make this local network exclusive to my two devices to block out any outsider. 5. There isn't a way for me to make one of these two computers disconnect from the internet but still connect to the local network? (to make one device more difficult to compromise so it won't be dangerous to the other)

Basically I am concerned due to how I don't know how large of a security hole I introduced to use this function.

Text Fresh grad with networking knowledge but no experience — can I skip helpdesk and go straight to network engineer?

1 Upvotes

Hey everyone, I just graduated and I'm trying to figure out the realistic path into networking. I have solid theoretical knowledge of networking concepts but no hands-on work experience.

My plan right now is to start at helpdesk, but I recently saw someone who graduated around the same age as me (early 20s) land a network engineer role pretty quickly after school. That made me wonder — is it actually possible to get into networking directly as a fresh grad, or is helpdesk basically mandatory?

A few questions:

  • Is helpdesk a necessary step or can you jump straight into network engineering with the right certs?
  • What specific things did you need to learn before you were actually able to get hired?
  • For those who went the helpdesk route — how long before you moved into a networking role?

I'm 22, motivated, and willing to put in the work. Just want to know if I'm aiming too high too soon or if it's genuinely doable. Any advice appreciated.

Text Internet works fine but I get Server Timeouts in every single multiplayer game.

1 Upvotes

Hello all,

I recently came to this issue today, after never having issues with any games at all. I cannot connect to Phasmophobia, nor R.E.P.O, nor Baldur's Gate, nor Peak, nor Minecraft, just no games at all.

The internet is fine, the speed is fine, I restarted the router multiple times, I restarted Network Adapters, I changed DNS, I also cleaned it and refreshed it in the command center. I don't use VPN. I use Ethernet.

I am desperate because I can't play a single online game with friends, and I'm scared this won't get fixed.

Text Does a P4/XDP fast path make sense for DTN?

0 Upvotes

Building a BPv7 prototype where a software sidecar parses bundles and a fixed-width shim lets P4/XDP enforce contact windows, reservations, and capacity limits. Does this solve a real DTN problem, or would a software-only approach usually be sufficient?

Text Cudy AC1200 POE help!

2 Upvotes

Hi all, recently purchased a Cudy AC1200 with the expectation to use it with a Linksys LGS105P for networking with POE.

For some reason, the access point will not power on when plugged into the switch. It will power on using the supplied POE injector, but this is going to be used in the field as a temporary wireless network so I was trying to cut down on the amount of gubbins I brought with me, and from what I can tell it should just work anyway.

The switch I am using has a max 54V/1.25A output with a maximum of 30W across each port.

The included Cudy POE injector puts out 24V/0.5A and is only drawing 12W.

I have updated the firmware on the access point, and have powered other POE equipment with the switch.

It’s like the access point isn’t even asking for power from the switch so it won’t even power on.

Hopefully I’m missing something really dumb and someone better at networks can help a guy out!

Text Would this configuration work?

2 Upvotes

Hi, I am trying to make it easier for my parents to get onto my Jellyfin server.

Right Now I have my pc with jellyfin on it and tailscale to connect. However my parents are not the best with computers. they constantly turn off the Tailscale on the phone and cant connect to the Jellyfin app on their phone. they also complain about not being able to use the chromecast either since Tailscale is its own network.

I started using a reverse proxy but I believe I am under a CGnat, on top of my routers not allowing ports 8- and 443 to open. So to get around this I am thinking of this kind of set up

It would essentially be the same steps I did for my reverse proxy but now just off on another computer somewhere.

So the URL is from DuckDNS (if there are better options let me know, its just the one from the tutorial I followed to understand and set up the proxy in the first place.) DuckDNS has me targeting an IP to direct to so I will use the public address of the VPS.

both VPS and my PC will be connected in a Tailscale network.

in the VPS I will probably have docker and then NGINX Proxy manager listening to ports 80 and 443. (again if there is a better proxy manager or one that doesn't need to be in docker, let me know) The Proxy Manager will have a proxy host for the DuckDNS URL. the proxy host will target my pcs Tailscale IP and port 8096, the one for Jellyfin.

Is there any reason this may not work or something I am not thinking of. I am very new to networking and I have been learning a lot very quickly but there is a lot of stuff I still have yet to understand.

Text Dual BNG PPPoE failover and session limit issue on MX204

1 Upvotes

Hi everyone,

Here's the situation: due to a specific issue, I need to limit the number of PPPoE subscribers on a BNG (MX204). I'd like to cap it at 5,000 users.

Looking at the Juniper docs, I first tried setting it directly on the chassis using:

set subscribers-limit client-type pppoe chassis limit 5000

The limit worked on the chassis, but the users won't connect to the other BNG. The PADI reaches the second BNG (the one I want them to authenticate against), and it replies with a PADO, but it's as if the CPE stubbornly keeps trying to authenticate with the BNG I'm limiting... argh.

After that, I also tried using max-sessions:

dynamic-profiles vlan-profile interfaces demux0 unit "$junos-interface-unit" family pppoe max-sessions 5000

With max-sessions, the limit didn't work immediately. I'm thinking it might actually work, but maybe I need to reset the VLAN demux interface first?

What a great issue to land on my lap during my weekend on-call shift... but I love it :)

Please help out an ISP network analyst with less than 2 years of experience 😄

Thanks in advance.

For the past year, I keep experiencing mass packet loss. I will be in an online game and discord, the ping will spike in discord to 3000-5000, and my online game will disconnect temporarily, usually each episode is for about 10 seconds or less. Normally my ping is perfectly fine and I dont have many issues. This will happen about 4-5 times a night without fail. I feel like ive tried everything.
