@JasGot said in DHCP Question...: I guess I am going back subnet school. I found it, it's in the faded greyed out area under the red rectangle.

@wrx7m said in Tool for Finding Rogue DHCP: Ran into this about 12 years ago. A guy on the dev team decided to setup his own DHCP server. Screwed up all sorts of stuff. Can't remember for sure what we did, but I think after we realized that it wasn't actually an issue with our known DHCP servers, we decided to talk to the dev team and found out that is what he had done. It amazes me how many people just don't think about it - they have a problem, they think they know how to solve it, and just slap something onto the network.

@Romo said in Unifi USG VPN from Behind NAT Firewall: Also add the changes to a config.gateway.json file in the controller to changes directly made on the USG don't get deleted on next provision. One reason I hate these units.

@brandon220 said in how does this work? Modems/IPs/PCI Scans: @JaredBusch example also is great for home use if you have IoT devices. I have an ERL behind a cable modem and this keeps everything I want separated from my normal LAN. That is a good way to practice this for business use

@JaredBusch said in Datto AP60: @WrCombs said in Datto AP60: @JaredBusch said in Datto AP60: @Dashrender said in Datto AP60: Of course, they are basically useless in this setup, because the APs are on a non internet connected network. No, they are not. @dbeato has clearly stated it works offline once programmed. Yes @NDC mentioned a rare condition where it failed. None of that matters. This unit is not going out to the restaraunt. He only needs the fucking thing to configure the tablets in the office. The restaurant will be providing s the wifi for the production closed network. this People are fucking too stupid to remember from the top of a thread to the bottom I swear. Anyway, you can use the Datto just like I outlined for the UniFi. Assuming you can get it programmed by someone. @dbeato Private messaged me and if that's the route we take he said he'd help .

In theory, you could even update the firmware on the UAP, in the future, by pre-downloading it on a device that presents it via a URL and then join that device to the aloha network. But that would be excessive amounts of work. Possibly the app could do it on an iPhone/Android device with LTE that is also joined to the aloha wifi.

OK late to the thread. We use a cheap travel router for this purpose. GL.iNET GL-MT300N think we paid $25 for it. Supports up to 4 SSID's and can do VLAN's though we only use 1. We can actual do wifi to wifi bridging with it. We use it for these wifi Sapling clocks that need to connect to a pre-provided WPA2-PSK ssid for initial setup. This is the newest version: https://store.gl-inet.com/collections/travel-routers/products/gl-mt300n-v2-mini-smart-router Can get these on Amazon now for $25

Man, I wouldn't think that would prevent a renewal. It does. Depends on race conditions, but it definitely happens. I guess I need to re-read up on the DHCP process - I thought (at least with Windows) that the client machine did a check at the 50% timeframe and renewed then, thereby never actually reaching an expired state. But that was 20+ years ago when I read the MS docs on it... so I could have a faulty memory. It does, but machines powering on and off and such can disrupt that process. uh, what? Sure, now if a machine is off, and the half way point, or the full expire time hits, sure, when the machine comes back online - it has to basically start over... The OP says the machine is loosing it's IP what appears to be overnight. OK, so let's assume the lease expired while the computers were in powersaver mode, or simply off. I would expect them to be turned on and simply go through a DHCP request - but the OP says a reboot it required to get back on the network. so something isn't working from the client side. So the NIC has been updated and that didn't solve it. Any chance the switch could be the culprit? Are there updates available for the switch?

@mary said in Optical Fiber Connectors - CompTIA Network+ N10-007 Prof. Messer: Is there a standard connector? Are they manufacturer dependent? There are standards, but many of them. There are a few that are pretty broadly standard, and generally manufacturer independent, but not always. You tend to buy from the manufacturer of your switch or whatever device it is.

@JaredBusch said in Optical Fiber - CompTIA Network+ N10-007 Prof. Messer: umm maybe a decade ago... Fiber is cheap and not all that complicated to have terminated anymore. We've been called in because dev firms and their normal IT support could not figure out the parts and connectors. It might seem easy to you and me, but to a normal SMB without a dedicated networking team, it's often hella confusing.

@Dashrender That's what she....

So chances are you will never run or even see an NTP master. But you might run or see an NTP relay, almost certainly. You saw me turn one off (pillow over its face) over the weekend.
