    Netgear Switch Fan Incompatibility - Go Fanless?

    If you are using that model switch for only two devices, you may be better off switching to a smaller, fanless switch. Unless it contains specific functionality you need compared to your standard home equipment, chances are you aren't losing anything except noise.

    Powerful router for gigabit ISP + IDS/IPS

    If you are building a PC for it, Sophos offer a free home version of their UTM. This includes IPS functionality. The only limitation is number of internal IP's protected (50). May be worth a look or jump on their forums to determine what type of system you would need to handle the volume of bandwidth you need. https://www.sophos.com/en/products/free-tools/sophos-utm-home-edition.aspx Also, it's worth noting that when security solutions reference throughput speeds, they are talking continuous traffic volumes a lot of the time. For example, for a 1gb connection, they may recommend a unit capable of 500mb (random numbers here for example purposes). With almost every connection, you rarely saturate the bandwidth consistently. This is usually more true the higher the bandwidth. So an appliance with 500mb capabilities would usually be suitable for a 1gb link. Further to this, if it is performing actions like SSL inspection, this can be extremely CPU intensive and can dramatically reduce the potential throughput depending on the complexity of the cipher suites it supports. Companies with large bandwidth connections usually are better off having a dedicated device handling SSL visibility that hands the traffic off to other security solutions so that they aren't bottlenecked.

    Hypervisor Comparison.

    Linus has just done a video on this, currently on Floatplane. Should hit youtube soon if it hasnt already.

    Can i run a VM?

    Simple answer is, yes you can. The biggest issue is with such old hardware it will be painfully slow. As in you can start your Windows 7 VM, go have some lunch, and maybe it'll have started by the time you return. Windows 95/98 wont be anywhere near as bad but the newer OS's will take a long time. I'm guessing you're budget limited if you are using this hardware. However if you can manage it, try look into some second hand hardware. If you can find a Core 2 Quad with a motherboard and DDR3 RAM, it will help quite a bit. Obviously the more recent you go, the better off you will be. If you can stretch to a 2nd Gen Core i series, you'll get VT-X support (on some models), and the experience will be much smoother. It all comes down to your budget, if any, and what performance you're prepared to put up with.

    Computer to do everything.

    A couple of thoughts. - Don't aim for a fanless PSU. Aim for one that will turn the fans off when not under load. Better to have cooling available for when it is under load. - Same applies to the graphics cards. Gigabyte have models with 'Fan Stop' where the fans won't spin unless necessary. I'm sure other vendors have similar. - Go for a large case with good airflow. Gamers Nexus does a lot of case reviews with noise and airflow considered. With all the hardware, giving it room to breathe will help keep the noise down. - For storage a possible option may be to go with a NAS. You can throw a few large drives in it (4 x 4TB for example), create shares to whatever size you want (or leave the size limits open). I have a Netgear NAS with bonded gigabit nics. This is where the majority of my VM's reside for my hypervisor. Speeds aren't incredible, but not bad considering it's running the VM's off external storage. Would be a handy way to have a large storage pool without multiple mechanical drives in your case and doesn't lock you in space wise. - Wouldn't be concerned about using AIO liquid coolers. They are easy to install and don't require any special knowledge. Lots of videos you can watch on the subject. Helps with the noise levels also. Considering you are running multiple VM's, an option like Unraid or a different KVM hypervisor may be a good option. Yes, unraid has a cost, but its not high. It would also allows for better allocation of the computers resources avoiding the main system (Linux Mint) having any overhead on performance. Likewise you could dedicate the 1070 TI to just your main system so the others have no impact on it. Grab any old graphics card for hypervisor management. I got a cheap GT710 for mine (fanless, low power, small footprint). Hope this helps.

    Forward a port on Telstra smart modem

    Definitely make sure the PC running the server has its firewall open for this port as mentioned. This could be blocking traffic. Also may be worth setting up a static IP address for your server so that there is no risk of it changing. If troubles persist, worth trying a dymanic dns service to map to your IP. I have found that has helped with Telstra connections in the past.
  7. I currently run a 7820x. I was thinking of maybe going to the 9920x. It has the second highest base clock, and matches the best turbo boost scores in the range. With 12 cores it is a nice little bump over my current CPU. But because it isn't jam packed with as many cores as the 9980XE, it may offer better OC'ing headroom. Hard to tell until some more reviews are done of this latest HEDT release.
  8. I am not sure how good the ASUS OC tool is (maybe someone else can advise here), but I have seen tools that help you configure OC from other vendors that push higher amounts of voltage than should be required. May be worth taking the time to perform some manual OC'ing. Gigabytes EasyTune tool makes my 7820x instantly unstable. It'll usually boot but wont last long.
  9. Heat would likely be your main issue. Some temp information would help. By changing from the stock cooler to the CoolerMaster Hyper 212 Turbo (http://www.coolermaster.com/cooling/cpu-air-cooler/hyper-212-led-turbo/), and applying some Thermal Grizzly Kryonaut, I was able to drop the temps 20c at idle and almost the same at full load. Running mine now at an all core OC of 4ghz. Could potentially go higher but the other system components are low end so haven't tried to push it more.

    ESXi login (ssl issue)

    There is a large range of different cipher suites that can be used for SSL. I am not sure which one ESXI uses exactly. However, if a security solution doesn't have the ability to handle a specific cipher being requested by a service, they will attempt to downgrade the connection to a lower (less secure) cipher that they can work with. For example, an ECDHE cipher might be downgraded to RSA 128. This then allows the security solution to decrypt the traffic and inspect the traffic to make sure there is no malicious content. This is what I assume is happening in your scenario. Unfortunately some services will not accept a downgrade in the cipher suite used in order to maintain security. Lower grade ciphers are also easier for criminals to break, so if a MITM attack is in play, a weak cipher can make it easier for them to view/change the traffic. With most consumer based security solutions, its often the case that exclusions don't actually completely exclude traffic. Or, in order for it to be successful, exclusions need to set up in multiple sections of the settings. E.g. Exclusions may be set for file anti virus activities, but still be enabled for IPS or Firewall components. Which means it will still intercept traffic for some of the functionality. You can usually get it to an operational point but it can require a lot of tweaking. Keep an eye out for browser plugins too. Hope this helps.
  11. Just to make sure everything is installed correctly. E.g. Your motherboard has multiple PCIE slots but only one that runs at PCIE 3.0 16x. The other is PCIE 2.0 1x. This could seriously choke your performance if the card wasn't in the ideal slot. It's just being thorough as a troubleshooting step.
  12. Also recommend trying the system with minimal connections. If something isn't absolutely needed, disconnect it. Your CPU has integrated graphics, so disconnect your GPU. Disconnect case USB headers. Essentially, eliminate absolutely everything that isn't necessary. Regarding standoffs, they do need to be aligned to your motherboard. Cases will have standoffs for multiple different sizes of motherboards, so some may not match up between different boards and would need to be adjusted. The idea of building the PC outside the case is also a good idea. Just one more thing you can potentially eliminate.

    5820K - Should I upgrade?

    With 6 cores at 4.4ghz, I don't think you'll see a huge change in performance. That processor still does run very well. However if you plan on only playing specific games that would benefit from an upgrade, its worth considering. Check for some comparison videos. There are some that are comparing multiple 6 core systems from different gens (5820k, Ryzen 2600, 9600k?). Should give you an indication of how the processor performs against current gens.

    Core 2 Duo E8400

    Earlier this year, I used a E8400 system in my garage. Used it for watching media. It had an SSD and a GTX 750. Was fine for media and streaming at 1080p. Even some basic gaming. However I purchased a new processor for it, a Q9505 (this is a Core 2 Quad at 2.83ghz). It was only $30 AUD delivered. This made a pretty big performance increase. If you have an older system with the E8400 already, along with a SSD and reasonable graphic card, then its worth upgrading the CPU and it will do the trick. If you need to upgrade too many components then, see what you can re-use from the system (e.g. Case, PSU, HDD), and buy a few new, low end parts to give the computer life for a few more years.

    SuperMicro Supplier Canada, Toronto area

    While these are primarily targeted attacks, for business use, be cautious of SuperMicro. https://www.bloomberg.com/news/features/2018-10-04/the-big-hack-how-china-used-a-tiny-chip-to-infiltrate-america-s-top-companies
