@JaredBusch said in How can I build this displaylink driver for fedora 29:

I have a standard Dell USB dock but want to use it with a Fedora 29 user.

https://github.com/displaylink-rpm/displaylink-rpm

That repo has a pull request in for the Fedora 29 updates, but I figured I could build it early for testing. Also I want to get more familiar with doing this on Linux in general.

I have no *devel bits installed on my system. Obviously, I can clone it down and run make, but I wonder if I need any other resources?

Inside the "ci" folder there is a script to let fedora downlad everything and compile via makefile

@Obsolesce @black3dynamite so this chocolatey could be the missing bit to speedup redeployment of a win machine as I do with linux+ansible+current distro's repo... I will check it.

Oh it's amazing.

If you have Ansible already, I'm with the "only backup once in a while."

Or ever, is there really a need to backup at all?

Well Windows patching and applications install is a pita. I will look into chocolatey. Wasting a day in reinstalling stuff in attended mode is not on my plans...

Do you have a lot of apps to install? VS is a big one, that should be able to be automated.

Would storing a copy of installers help?

VisualStudio Community is in Chocolately actually.

Oh wow, cool. Had no idea.

So is SQL Server Express.

That is how I seutp my Win 10 VM for some dev stuff.

and many other things! IT has been awesome ever since I found Chocolatey!

So I've tested choco in a vm. So far so good. I need to be acostumized to the cmd line and terminology. As a side this has pointed out how slow and huge win packages are... Used to apt-get this is super sloooooow.
They also apply kb fixes in the process and this is c00l!

I'll dig a bit in their repo... but this could resolve part of my problems.

I've ton as each customer requires specific apps helpers and similar... While code.is in winform (sob) or wpf and c# or vb.net (sob), hw requires axiliary tools like native machine vision tools from the hw vendor or libraries to interface actuators or other similar stuff. Heck for a job I even had to install qgis!

Would storing a copy of installers help?

Don't know: apps get updates I should remember to store any updated installer... Maybe useful. But currently I'm going to check chocolatey first...
It seems to better fit my need of reducing backup overhead while impreving rebuild times and ansible should lead to a certain level of reproducibility too (not sure: I use it on linux only and windows modules seem quite poor)

@dave247 said in Why Are UTMs Not Recommended Generally:

@scottalanmiller said in Why Are UTMs Not Recommended Generally:

If you just want VLANs, there is no need for more than two ports on your router. You only need more than two ports when you have more than one LAN, not more than one VLAN. So that matters as to whether you need more ports or not.

I don't fully understand where you are coming from here. I have a different VLAN for each different network (LAN).

Are you talking about having sub-interfaces?

I think he means you have different phisically separated LANs

@Pete-S said in Rethinking my backup strategy:

@matteo-nunziati I have a suggestion. You could potentially move your entire development environment off site to the cloud/colo/whatever. And then just use your computer to remote in and do the work.

With your uploads speeds it is much faster to just run remote sessions. And with that setup you are not dependent on your laptop as it is a single failure point for your business.

Or get a fiber connection or whatever it takes to get decent internet speed. 3 Mbps is not enough.

This. 3 mbps download is enough to work remotely, but not enough to keep everything onsite and do online backups. Find a host/server in a data center to see your work on, and handwork for backups becomes a non-issue.

I have a couple of places that are in the US, but you're based somewhere in Europe, right?

Yes Europe, Italy namely.

@JaredBusch said in Rethinking my backup strategy:

@matteo-nunziati not on the backup topic, but you said you switched to windows for VSCode. Why? That is completely cross platform.

@aaronstuder
Ok I'm an asshole. I've just seen my wrong reference to vs code in the original post :/.

It is visual studio 2017.

@JaredBusch said in Rethinking my backup strategy:

Visual Studio not visual studio code. It is the "legacy" devenv. Currently net core and vs core do not support some of the features I need.
Vs code would be great.

backup days

CONTEXT
It is almost a year since I changed job and now I'm a freelancer with my trusted Thinkpad T440 (lenovo and trusted in the same sentence XD).

As a freelancer I'm asked to develop a lot of code for .NET so I've switched my main OS to windows (due to Visual Studio Code 2017).

BACKUP NEEDS AND BACKUP CHAIN
I've installed the free version of Veeam Agent and I'm backing up my entire computer. Let me explain the goal of the backup first:
1- all of my source is hosted online in bitbucket/git
2- all the docs are online in gdrive
3- basically backups are required to speedup windows restoration in case of disaster as it always requires tons of hours to setup a windows OS with all the required applications (linux is way faster in this)
4- backup jobs run once per week

My current backup chain is: laptop w/ veeam => home NAS (small 2bay , slow cpu) => backblaze B2 sync (integrated into the NAS)

THE ISSUE
The chain is ok but the veeam settings are killing my internet connection without providing real time advantanges: I've a 3Mbps upload speed.

Veeam is currently set up to take a full snapshot of the laptop and do incremental backups (with dedup and compression set up for WAN). Retention is 14 backups. The issue is that when you take the 15th+ backup, you start merging the base snapshot forward.
1- Merging the snap is as long as do a full bakcup (usually around 1:30 hours or 1:45)
2- once the baseline snap is updated I need to reupload to B2, which means that my NAS is still moving something like a whole new snap of the laptop (baseline snap + new increment). which means soething around 100GB.

MY IDEA
As backups aim is mostly for fast windows restoration I was thinking about a couple of things:
1- as incremental backups still require a lot of computation time and a lot of upload time, maybe it would make more sense to simply do full backups every time.
2- as I'm just snapshotting the laptop to speed up restoration I could reduce the frequency to 1 backup every 2 weeks giving a bit of "rest" to my uploads.

YOUR OPINION
Can you suggest anything else?!

@Obsolesce said in VPS Backups:

@scottalanmiller said in VPS Backups:

@Obsolesce said in VPS Backups:

Rather, you temporarily use a snapshot in order to create an image or backup, then the snapshot is deleted and merged afterwards.

That's called exporting a snapshot. There are cases where what you describe is the process. But it's important to understand that the resulting "image or backup" is called a snapshot still. And what you are describing is the process used to produce the snapshots that we are talking about.

Veeam, for example, takes snapshots, that's how it works. All non-file based backups are snapshot based backups.

File backups work from the filesystem level. Snapshots are the only way to backup from the block level.

Ya that makes complete sense. I don't know why I was thinking down that path.

THIS ^^^^^^

@hobbit666 said in Why Are UTMs Not Recommended Generally:

I understand the no need for UTM to block stuff as most routers will do it. But what about things like content filtering? How do you block unwanted websites being accesed?

usually with proper VM acting as content filters/proxies

@Obsolesce for machine I would use native snapshots. For data anything able to backup to b2 on a given schedule (cron job, systemd timer, whatever). Maybe if there is a db inside the vm it would be better to dump contents... I don't know if any b2 related stuff is db friendly.

@Obsolesce are you talking about the data or the whole machine? Providers usually offer snapshot capabilities for backup within the DC infra.

Also 2.4.2 is kind of old. Some things are being deprecated soon, so you will want to either install from EPEL or use pip to pull in a newer version.

Another "CentOS problem" that "doesn't exist"

Well it's weird. Idk if CentOS hasn't caught up with RHEL yet. Ansible is at 2.7 in RHEL. I have no idea why it's lagging so far behind in CentOS.

oh, weird.

But even Fedora lags behind a little. It's getting better but I've seen it as far as 2 releases behind before.

I always download it from upstream

@wirestyle22 said in Ansible 2.4.2.0 on CentOS 7--ping module isn't working:

@black3dynamite That looks so weird to me

shouldn't the host be ansible_host=hostname ? Did they change that?

Please post your inventory well formatted as code. It should contain a list of targets and should be passed to ansible with the -i flag. Also check the docs: https://docs.ansible.com/ansible/latest/user_guide/intro_inventory.html

Not bad news, but honestly, I can not stand R language

R is really meant for math, using it for programming or running anything else is painful because it's not designed to do anything else.

And still I prefer matlab/octave

@wrcombs said in Gmail Rules for Mass Emails?:

I know there is a way to set it up: I have tried various ways - setting filters for : from and TO : using the email addresses that are attached to each of the emails from the forums ( we use a mass email forum- you send out an email question, and it goes to everyone, that is a part of the forums) - Is there a way to set a rule so it goes straight into a different inbox and does notify me?

Thanks

Try searching in the "original"message. Here you can find some patterns in the header. By Using the "contains" filter, gmail checks the header too.

Also if you have gsuite you can manage additional routing rules.
