  1. They are not currently set as private, but i am fairly certain they were when i set the manual IP addresses on both boxes. im not 100% sure but i think i did try an iperf test with the bridge. i may have to try that again this weekend.
  2. Those ports should already be open for private networks though correct? Because initially the NICs were set as private networks. Windows firewall was just blocking all traffic on them anyways. are there maybe some local security policy settings that have to do with auto/manual nics and the firewall? As far as the bridge is concerned, it seemed to me like the secondary box (where the bridge was) was treating the network bridge as a 1Gbps network instead of a 40Gbps network.
  3. Both current boxes are running windows 10 pro. The only way i knew to pass the uplink through to the direct attach link was to bridge the NICs. Turning the firewall off for "public" connections is what i have already done, i just wasn't sure if that's something people do and windows really likes to nag you about it if you don't disable firewall notifications.
  4. QSFP Switches are not made in a form factor i would keep in my apartment and i don't know if any of them really support Ethernet operation. I did also try linking the NICs together on the server box and connect to the internet through it, but for some reason this limited any file transfer speeds to the speed of the host network (1Gbps) which made it pointless. I might consider this again if there is some other way to do it that doesnt involve making the second box also my dns/dhcp server..
  5. In LTT's Recent revisit to the Jellyfish Fryer: They have the server connected to its client machines using a Direct-Attach configuration, with manual IP addressing. I have a question Im hoping someone here, or maybe some LMG staff; Can help me with. In my home Setup, i have a fairly built gaming tower, with minimal SSD storage, and a second box, somewhat of a home-lab focused system built with some older HEDT parts, and use it to expand the storage from my primary box with a few Mellanox Connect-x 3s and a direct-attach configuration. Both boxes are running windows 10 pro. When i initially set up the direct attach link, I came across an issue where the PCs refused to talk to each other over the direct link. I didn't find much info on doing this when i looked, and the only way i found to get them to talk to each other, was to set the adapters as "public" networks and disable the "public" firewall on both machines. In the recent LTT video, Linus made no mention of any special firewall configuration on the client windows box to get both machines talking to each other, so i have to assume that one of the following is why: 1. They didn't have any issues because the client machine wasn't connected to a separate DHCP enabled network. (windows seemed to only care about blocking traffic on a manually assigned network when also connected to a DHCP network on another NIC) 2. Windows firewall doesn't block a connection with a non-windows machine for some reason.... 3. Updates to windows/windows firewall make this just "work" now. 4. they did need to do additional firewall configuration and just didn't mention it. I am planning on migrating the home-lab box to a new tower i am currently putting together (which i have loaded with Windows 10 Pro for Workstations), and I want to maintain the direct attach configuration. But hopefully this time do it without disabling any firewalls. What other ways can I accomplish this? Thanks.
  6. I was using an app that showed APs graphed to channels and saw all the other APs hopping channels too. that would mean everyone else was already experiencing the same connection dropouts too. in a perfect world all the APs would agree on which channels to use to be least disruptive or everyone would manually set them, but that isnt the case. I would expect that if my being in between channels was causing other connections to not work, would my connection not be worse having 2 sets of overlaps rather than just one?
  7. I use to always have issues with my wireless connection dropping out randomly. living in an apartment complex where there are 30 other APs broadcasting in range all set to automatically choose a broadcast channel, they start jumping around all the time. If you ever have your wifi dropping out on you regularly it is because your AP is switching to a different channel. I always got the best use out of 2.4GHz wifi setting it to an in between channel. I dont use 2.4GHz wifi anymore and my current AP has openWRT running on it so i have access to DFS channels that are completely clear for indoor wifi and use that instead.
  8. Here is my small network.
  9. Any and all "free" VPN services still have to have some sort of income. The vpn is not their product. your data is. they make their money selling your data and on the adds in their app.
  10. I ended up getting help elsewhere but the issue was being caused by Windows Firewall. I have set the main network connections to private and leave the windows firewall on for private networks. the direct connection is set as a public network and windows firewall is disabled for public networks. I then had to set jumbo frame MTU to get 10Gb/s over the link
  11. So I recently discovered some 40gb dual port QSFP cards on ebay for $13 and decided i wanted to try out getting a link set up between my main pc and my server box. 2 cards and a cable cost $40 total so why not? The cards I ordered were Sun Oracle OEM Connectx-3's. i had them both on a test bench and flashed them both to the latest CX354a-FCBT firmware to get 40gbE. I currently have one card in my main PC and the other one on the test bench so i can figure out how to configure them before i take down my server to install the card. I have the latest available WinOF drivers from mellanox on both machines, Both cards are set to ETH for both ports, both are showing 40gbE links and showing sent/recieved traffic in status windows, and I have link and activity lights on both cards. But i cannot get the Two PCs to talk to each other and i am not sure what i am doing wrong. I can't get either machine to ping the other. I have tried leaving them on autoconfig IPs, and setting manual IPs. both machines are running windows 10. I am not at home right now but I can try to provide additional information if any is needed. Any help with this would be appreciated.
  12. Ill be packing mine in one of these for the drive: https://www.amazon.com/Desktop-Computer-Carrying-Processor-Keyboard/dp/B07JPDY8HV/ref=pd_lpo_sbs_147_t_1?_encoding=UTF8&refRID=4ED24E8Q942VCSKK7R3F&th=1
  13. I might be able to get a hotel room if i have someone to split the cost with. Im driving in from Spokane on friday and leaving sunday night. i also got a BYOC ticket.
