Well I've eliminated 7 servers, down to 2 servers in a HA pool...

And in the process of doing that I've consolidated all of the network shares dispersed across those 7 servers into a single VM.

Making backup via Shadow Protect and XO far more straight forward..

There is no simple way to know this. If he sets up a machine that will listen on every port, he could then test with a port scanner from internal.

Good way to get written up if they don't have permission as well.

I think "getting around the rules" is already assumed at this point.

Wouldn't mind to do any port scanning. A good admin will see this, and there is probably a reason your friends net is locked down. Scanning the network can get his butt faster on the street than he can write pcap.

Anyway, just for educational purposes: Use SSH port forwarding, maybe to a host at your friends home.

This will route every traffic to the desired target through an encrypted tunnel. You may bypass most firewalls by using common ports this way. A bit hard to explain, but there are plenty of tutorials available.

But you mentioned tcp/8080. That port is often used as a HTTP proxy, so your friend probably does not have a direct (routed) connection to the internet at all.

DDoS depends on public addresses acting as a clients pounding your DNS server with thousands of recursive queries at once. If your DNS server isn't public, then it isn't a open resolver, and a client on the internet can't query it directly.

In our case, we have a local DNS server, available to the internet, as a backup to our ISP-hosted DNS. This server is typically vulnerable. But it's set with a higher cost so it won't be used unless ISP goes down.

@halizard Awesome, I'll have to give it a whirl.

@scottalanmiller said in Cloning XenServer on USB or SD:

I assume that there is only one partition. You can check yours but there should not be multiple partitions.

This is how XS7 sets it up, at least...

sdb 8:16 0 74.5G 0 disk ├─sdb1 8:17 0 18G 0 part / ├─sdb2 8:18 0 18G 0 part ├─sdb3 8:19 0 512M 0 part ├─sdb5 8:21 0 4G 0 part /var/log └─sdb6 8:22 0 1G 0 part [SWAP]

Yes, it should boot up just fine.

Why do I get the feeling no one has ever tested this, haha.

@scottalanmiller said in Updating Windows from the Command Line:

Keeping a system up to date is very important and doing so from the command line can be one of the easiest ways to do this on Windows.

Updating a Windows system, server or desktop, can be as simple as running this command as an administrator:

wuauclt.exe /detectnow /updatenow

If you only want to look for the latest updates without applying them, you can just run:

wuauclt.exe /detectnow

Also:
wuauclt.exe /a /detectnow

At least one person around here is running their own controller.

The way I interact with everyone may change in the near future (like I'll actually help people for once). This server is going to allow me to learn rapidly.

Any reason that you are looking to build your own? The hosted version gives you 100 free nodes. That's a lot.

Experience only. I have their hosted solution for the things I actually need to work 😄

xByte would be a great option, I bet that they would have a solution for you with this.

What I think of every time I hear the phrase "kernel panic":

So, apparently the version of raspbian that DIY temp sensor is on, the version of gluster in the repository is 3.2.7. Which just happens to be the last version before they broke backwards compatibility, so the client on the pi can't connect to the gluster servers running 3.7.9. I'm building from source currently, and if it works, I'll post the condensed version of how I got it working.

I have a cross compiler VM somewhere, but I won't have a chance to look before the next weekend.

I think the problem is that the Pi2 is 32 bit, and the programming expects 64 bit now. So, in theory, a Pi3 would work.

Erm, can be yes. My CC build is also just 32bit, pretty sure. And the gluster stuff is 64bit arm?

The errors I was able to read during compile were complaining about variables defined as int64w, which wouldn't work so well on a 32 bit platform I don't think.

I can define a long int (64bit/8 bytes on most platforms) just fine on any 32bit CPU. You can even do that on a 8 or 16 bit uC. So probably the failure is somewhere else?

Possibly, let's see if I can find that compile-time error here.

I learned something new today. I have been using the shutdown command for years. I never realized you could rename a PC with it.

shutdown doesn't do the renaming, you just have to reboot after you rename.

I use "m" instead of c for computer name

/c is the comment for the logs to tell them that you just "Renamed Machine", it doesn't rename it, it literally puts "Renamed Machine" into the reboot logs.

Ok. Got ya.

Considering it bounced most request between 20 and 300 random locations in the world for the original address, I'd guess pretty well secured.

But you could just chase the hops back to it's source eventually, so they are adding encryption to it.

Which is pretty awesome.

I'm unfamiliar with the Server Core setup... but can't you install these drivers as part of the Windows installation process?

Storage yes, but I'm unaware of a simple way during a stock install to include other drivers. The storage ones are requested, and necessary, during the install. Otherwise the installation location does not show up (unless you don't use VirtIO block devices.) You can definitely add the tools into an image, and there is probably a way to include Ethernet devices ahead of time, but I'm not used to the installation process to know where it happens.

I just select all 3 of the INF files and go... It's always installed everything for me, lol... Just point it at the folder for the right OS and 32 or 64 bit... (Note: This is the way I did it in Scale v4.3... I've not had a chance to use their newer stuff yet.

At what stage are you selecting them?

During the install process... the same place where you go when you're picking the storage drivers.

I rarely do modifications at that stage. Still, handy to have a simple option because a lot of people will get the install done and find that there is no networking and need to know what to do at that point. 🙂

@thwr said in Installing VirtualBox inside a virtual machine?:

Oh, a spin-off thread. Missed that.

Like I said, Hyper-V can do nested (or V-in-V) virtualization. Even when running on a desktop machine like Windows 8 / 10.

Just did that myself because we had to extract something from a vagrant file. Can also be good for evaluating other (type 1) hypervisors like running Xen on top of Hyper-V.

It's good in some cases but never ever think about production usage (yet).
That's because it is bare metal and never actually runs ON Windows 10, Windows 10 always runs on it.

You are right, I tend to forget that at times 🙂

Why on earth do you give an instruction with a hash in it?

Why not use the MySQL SHA1() function?

mysql -D asterisk -e "UPDATE ampusers SET password_sha1=SHA1('CHANGEME') WHERE username='admin'"
