@Pete-S said in Utility to change raw data?:

I think I might have a solution with dd and printf.

printf "8718\r\n0x23abc\0x00" | dd of=raw.bin seek=2345 oflag=seek_bytes

Something like that.

Interesting. Makes sense though.

Still preferred fallocate instead of dd to create a swap file?

dd if=/dev/zero of=/swapfile count=4096 bs=1MiB && chmod 600 /swapfile && mkswap /swapfile && swapon /swapfile && echo "/swapfile swap swap defaults 0 0">>/etc/fstab

Still using swap file? Memory is cheap. I don't recall a server where I created swap partition or swap file.

Memory is NOT cheap, not at all.

It is if you own it. If you rent your hardware, yeah, it adds up.

Even if I own it, throwing away 2-3GB of RAM makes no sense. Now, if I own it, I can easily assign 4GB of RAM then remove it once installed, by why? That's harder to script and still no benefit.

It's a bad habit to see resources as cheap and so waste them just because you can. Extra memory doesn't improve performance, it hurts it (just the tiniest bit). And it's not free, if you always apply twice as much RAM as you use (or four times, here), that gets costly one way or another. Either you wasted money overspeccing in the beginning, or you are stuck buying more now.

Anyone had any luck mounting SQL Server 2005 MDF/LDF to a new SQL Server version
You can move SQLServer 2005 to a new Server version by following this guide: https://solutioncenter.apexsql.com/restore-sql-server-backup-to-a-newer-version-of-sql-server/

@openit said in Building your own lab:

@scottalanmiller @Pete-S
Do we have any complete post or article on ML which describes how to build a Lab with design, like server, switch etc. arrangement.

Really appreciate, if someone can provide any links, which gives complete lab design, to prepare me as a good Windows System Administrator, which should include all tasks, activities a typical SysAdmin requires.

https://www.servethehome.com/

Some tasks would be setting up a monitoring alert system that alerts you of reboots, account lockouts, high CPU usage, disk usage, network, etc. Get familiar with using PowerShell to manage your Windows systems. Setting up a Dev or test to in order test your Windows or 3rd party applications before deploying to production.

What special case needs UAC completely off?

I'm curious about this as well.

Installing malware 🙂

How much data? How long is it taking?

Note: Use the -P/--progress flag to view real-time transfer statistics 🙂

260GB or so, nothing crazy. Not sure, ran it overnight.

Also, WTF... Who watches backups real time?

Ok HP clarifies and said USB A is not powerful enough to deliver a meaningful charge.

@JasGot said in Skyetel Postcards Redirect Issue:

I believe ./run.sh restarts all services, and I suspect that includes Nginx.

Yes, Nginx is inside a Docker container. But there are three.

All you need is...

systemctl start docker systemctl enable docker

And you are good to go. It's just a process that needs to be started like any other. There's nothing to know about Docker in this instance. Think of it as the server itself, it just needs to be turned on.

Found it -- test-compliance.

Lego is another good one from what I've seen. It does all 3 challenge types.

https://go-acme.github.io/lego/

Thanks, might have a look at it next time.

I went with certbot this time because it was very clear what needed to be done. Debian has a package for it's all you need to do is have a http server up and running and then:

# apt-get install certbot python-certbot-apache # certbot --apache

It will do everything for you - create & install the certificate, set up redirection from http to https, set up a job that updates the cert etc.

The site has instructions for every common OS (redhat, ubuntu etc) and http daemon (apache, nginx etc) combination.

Yeah certbot is the easiest. Lego is just more flexible and you only need the binary. Def start with the easiest for now.

@gjacobse said in NextCloud: Chmod user folders:

Oh - no - the syntax is incorrect for ownership.

sudo chown

Yes,

chown to change owner chmod to change mode (permission)

Remember you can always do man chown to see the syntax.

Wow, this is going to really change the way we use Mesh! Awesome stuff!

That seems to have fixed the issue

@scottalanmiller

Hi, Thanks for wonderful script that save my time.
Could You please guide me how we can run this script on multiple servers?

I tried foreach PowerShell method but it does not work.

From the ISE, load the script and then enter-pssession for each system. Once connected, run the script from the ise. Sorted.

Hmmm ... this from a little over a year ago.

Same "problem".

Routing is not magic. Errors happen.

That may be so, but the expectation is that the same errors would not happen over and over again.

FFS It is not the same. Are you stupid?

Jesus, calm down. No one pissed in your corn flakes...

No kidding. Don't go all Boomtown Rats on me. 😛
