We dont have an Active Directory, and whats the benefit of DHCP from windows server (I reckon its situations like these...)
Could it work with the main router, I guess cause it easier to have the DHCP on the main router, and I dont want configure clients to point to the new DHCP and I reckon DHCP on the main router is simple service that wont slow it down.
Hey,
I think this topic should be an auto-generated weekly topic, cause I foresee that I will have many WTF moments.
As an I.T generalist, I know a bit of everything, and VPN is the area where i wish I would know more, so without any further delay, here is the scenario.
I wish to create simple VPN connection/server using Windows technology for Windows laptops outside of the work office, and mostly everybody runs Windows 7.
Also note in that office, its Class C subnet with 30 users, so were working on the standard
192.168.1.x
Private IPs
The DHCP is provided by the main ISP router/modem (And I prefer to keep it that way)
My server is vm running 2008R2, and I added routing and remote access role only, and configured NPS policy for VPN profile connections.
And for the life of me I am unable to connect to the VPN successfully unless I specific manually to specific the IP address.
Which is stupid way of solving it, cause I have to configure the DHCP on the main router and limit it to stop giving addresses from 192.168.1.2 till 192.168.1.199 which is easy step, but its stupid cause even if that way it works 100% cause lets say for example my home is configured with
192.168.0.x subnet, that means I can connect to the work NAS at office which have the IP of 192.168.1.200
works GREAT, but what if a site that has subnet of 192.168.1.x already utilized it works and I can successful connect to the VPN but IP issues arise, for example if 192.168.1.200 is already utilized in my home I wont be able to connect the office NAS.
The only way to get it working currently it so change the subnet of the work office for something weird like 192.168.55.x this way I can grantee that VPN users will get an IP of 192.168.55.201 and it will work cause its very uncommon that any household ISP vendor private IP gives the users anything other than:
192.168.1.x or 192.168.0.x or 192.168.8.x where I live
And is the above VERY uneducated POOR MAN VPN have name ? and did you ever see people use it in VPN which is allocate subnets manually and change the subnet of the work reasonable solution ?
Hence the question why DHCP is not working , I KNOW I AM DOING SOMETHING TERRIBLY WRONG BUT WHAT IS IT, can you guess and win the price of slapping me with it ?!?
I tried ticking DHCP IPV4 Assignment but afterwards the VPN does not work and cant connect with an error 720
I tried adding another virtual adapter and plaything with that and then bridging it - didnt work
I tried playing with DHCP relay agent setting - added IP of router - Added new interface of LAN didnt work
I tried adding DHCP role in the server - didnt know what I was doing thus didnt work
More screenshots to help you out:
Thanks for reading this and helping me in advance.
Its posts/replies like this, makes me wonder why this site does not have ''mark as solution'' option given to the topic opener, and when done the topic will have green color for example.
But maybe that will be a double edge sword, cause it will block future answers and thinking on the topic...
Unethical reasons.
since KVM and usually other hyper visors allow you to play with CPU and core count of the guest VMs, I wondered if you can get away with limitations of other paid Hypervisors that limit the core count.
Not sure, just wondered what everybody else uses that tech for.
Hi,
So I have been seriously playing with KVM lately, and to test it out I installed it on ESXi 6.5 server as Centos 7 VM with the ability to pass VT-d extensions which is supported by ESXi (also workstation).
Why I did this, cause I need to test KVM on real server hardware, and the real server already had ESXi installed.
And I am liking it more and more each day, its stable and have better options compared to ESXi standalone server, and you can clone vms easily, of course I cloned the KVM guest server and made 2 KVM servers, and the ability to move VMs offline (not live migration) was very easy, and simple. I was not able to perform a successful live migration yet.
So this got me thinking, why would anybody run KVM nested ? one idea came to my mind is perhaps somebody can do the opposite of what I did which is to run KVM then run ESXi 6.5 guest machine, but the real head scratcher for me is WHY this is needed in production environments ? is it only a testing thing, that I can understand.
So why do you run nested virtualization, also I tested this with VMware workstation back in the day and I know that nested virtualization feature in VMware is stable, is KVM the same ?
Many thanks.
I just wanted to belong... thus my comment
Also its good to note that VMware ESXi free standalone server 6.5 is only limited to 8 vcpu per VM
so I think you can build a a good small server using there upcoming CPU.
Hey man.
I managed to generate keys (inside Linux environment using ssh-keygen -t rsa and use ''authorized_keys'' file on both machines) and things are alot smoother now, but going back to what you mentioned:
''Virt-Manager obfuscates the entries in the window on purpose."
Seeing you have many posts that deal with KVM, can you help me sort this out. How can I fix this? does it need something like ssh pass-wordless login to resolve, but in Windows environment (virt-viewer) they dont have ssh... so how can I resolve it?
There is some truth in this, but the initial price for there printers are alot cheaper with tons of features compared to the rest.
But for me if it was BW printing I will go for samsung m2070w after seeing it in action
KVM with Virtmanager.
Centos latest is my preferred KVM host.
And Fedora LXDE Spin is my preferred Virt-Manager choice, I use it from inside Windows using Virtualbox.
Cause it resembles the old ESXi Philosophy with Vsphere C# client
And you can do whatever you want with it, and for free. Especially when you use virt IO drivers for network and disk, you get nearly identical bare metal speeds.
But sadly its lacking other tools to allow users to connect and use the VM, you will have to do this from inside the VM like RDP and VNC.
Sure I can just VPN to the 2nd office and check.
I got them the color one caused I liked the software of the m2070fw
Due note that I noticed the color variant have metro like software interface which was buggy, but fear not just head to m2070fw and download the software for it and it will work fine (network scan)
And it is ... Samsung c480fw
Colors are great, but paper tray is a bit on the small standard side, other than that its great.
Since you said single side scanning, I will suggest the Samsung m2070fw it might be cheap, but man it does everything. and on the network using WiFi with very easy to use software.
Its black and white only, but there is another version for it with colors, But this one is very decent A4 printer, and dont trust folks that tells you it can work only for home, I have seen 20-30 people using this small thing and it working. But sadly there is no scan to email function. just network scan.
I found this as well:

BUt no windows port 
I wonder how long and much will it take to me port it
While I understand what your saying, and it is the ''pure way'' its not that I dont want to learn new things, its just I want to be quick at deploying VMs, and having a tool for me is much preferred.
But will try to keep that as an option, I do deal with virsh shell, but in very humble mannor, like Virsh Destroy and list --all and start/shutdown. But down the road I will learn more.
Thanks for the Web virt suggestions, I gave that try and didnt like really... but that got me thinking to Cloudmin even thought its not free.
But it seems I am stuck with Virt-Manager for some time, Btw I came closer to fixing the weird typos when I use virt-viewer In windows, apparently I have to put my mouse on the toolbar insert keys to type keyboard stuff, but even when I do this, the keyboard input i type is not the same as displayed for example if I pressed
YES on keyboard it will display something else, however if I pressed multiple times it will display YES eventually ... dont ask me why this is happening... I played with locale and keymap and all the keyboard options, this is the max for me.
KVM + Virt-Manager is good for hosted enviroment that only 1 person will interact with. Unlike ESXi standalone host, it has support for VMRC which is 40 MB download executable that allows any Mac OS X/Windows/Linux to connect to VM from command line.
Hello all,
So recently i began learning more about KVM, and loving it.
I come from ESXi background
And for me using anything but minimal hyper-visor is not preferable, I look at ESXi 6.5 and previous and the hypervisor is ~350 MB, basically what I am saying is that I dont want to use Proxmox.
So I found out the best way moving forward is the Pure (and free) KVM approach, which is to install Centos latest minimal then:
Install ifconfig:
Check CPU support for Virtualization:
2) grep -E '(vmx|svm)' /proc/cpuinfo
Install KVM:
3) yum groupinstall Virtualization "Virtualization Platform" "Virtualization Tools"
And when that is done, congrats you have KVM enabled machine, you will need to stop the firewall, if you wish to SSH to it or allow rule to the target machine to allow ssh.
The best way of playing with KVM I found it, in single machine is with Vmware Workstation, cause its the only Type 2 Hypervisor that allows the VM guests inside to have Intel VT-D and AMD-V (I wish virtualbox would have this, but it a feature request was placed since 2012 and I doubt any further progress is being made)
So afterwards I install 2 centos VM with KVM and 1 vm with latest Fedora LXDE spin and install Virt-Manager using: yum install virt-manager
And connect to them using Virt-Manager and everything is working out smoothly... however are you aware of other simple tools to manage KVM, Virt-Manager is okay, and I like the concept of having similar C# vsphere client to manage KVM, but it seems to me abit lacking.
Even there virt-viewer packages (for windows version 5.0)are non nonfunctional, I could only view my guest machines, but for some weird reason when I first connect to VM using virt-viewer I could only type 3 letters then the keyboard will be disabled ... go figure
So what other options do I have, bare in mind I want to keep things simple and dont want Domain name, and stuff like that, I would like to connect to my KVM via IP, what do you guys use :
This looks interesting as well :

Hi,
So the recent news of AMD supporting Windows 7 with drivers, got me thinking a bit.
I am planning on an i7-7700 (non K) setup using this motherboard:
Z270 SLI PLUS
https://www.msi.com/Motherboard/support/Z270-SLI-PLUS.html#down-driver
However it does start that have drivers for Windows 7
I dont understand, can somebody shed more lights into this, cause I heard Skylake only will work with Windows 10.
Is it possible ?
My Goal is to provide an SSL an intranet site, and keep people using it via LAN and not WAN.
But I dont want to bother with purchasing an Domain name, also I searched and Lets Encrypt doesn't support this it seems, what are my alternatives (I prefer zero cost solutions)
I'm more interested when will they release the VM/container that will allow users to collaborate and edit files like office 365 on the web.
I played with the WebDav file sharing element inside the desktop software and it was meh.
Well the title says most of it, I am abit youngster in the I.T admins lounge was usually 1st or 2nd tier help desk I.T.
Lately I feel like I have to check the network equipment and server more than one time, even if its something I know I did safely previously and it should run 99.99999% fine, but I have to check it and then check it again after some time and maybe on weekends.
Is this normal for you guys or I take it too seriously and cause it is my first I.T admin/supervisor job.
I hope this effect goes away eventually, or is that what makes a good I.T admin ???
