A lack of a backup and DR strategy was one of the things I was brought in to remediate. No. There are no backups.

Oh no.

Dear God I pray that you have backups outside of the environment. Please tell me that you do. Another NAS, tapes, diskettes, something?

This just reminds me of the Rent-A-Center/Conn's/Colortyme, "Take it home today and pay out the nose for the next 7 years" kind of schemes. You can get more blood out of a turnip by financing over freaking long periods instead of being a grown up, saving your pennies, and actually getting it when you can afford it with cash.

I always try to make sure that I have an administrative local user to every system, just in case I cannot get to AD.

That, and never have AD on top of something that depends on it. That's like locking your keys in your car.

Yup. Our SAN is isolated from the rest of the house network physically. All authentication between the SAN and the host should never even touch AD just in case of things like this.

Sometimes playing what-if is a good exercise to keep bad things from happening as far as security, reliability, and recovery.

We still need to see the logs

[root@xen2 ~]# tail -n 100 messages
tail: cannot open `messages' for reading: No such file or directory

might have to cd to the logs folder and try that tail again.

Not cloud-based, but have you checked out osTicket?

As far as I am aware of, this started for me today. Not a big deal for me, but wanted to bring it up, if needed.

What's the end goal with this device?

Once this crisis is over, I recommend going over this when you have free time.

Its not complete but its a really good start.

Learning Linux has always been something I've wanted to do, but have never been able to find the time to do so in a work environment.

I totally understand. Either on your laptop or as another VM in XS, I would setup Linux. Then just take a topic or 2 a day and learn a new skill. After a while, you will be building one skill on top of another.

Replaced my 12-year old 42" 1080i LG plasma with a 55" 4k LCD LG. I knew about that one. What I didn't know about was the Yamaha 5.1 Home Theater system from the Dad-in-law. I was in geek heaven for a little while. Then discovered that my Home Assistant conveniently interfaces with the Home Theater system. Added bonus. Plus, the CEC kicks in. So now, I can turn on at least the TV and theater system at once with my phone and home assistant.

Now, just need some wifi-enabled RGB LED lightbulbs to begin creating scenes.

Can you tell what has changed between working conditions and now? I know you said that you're at 6.2, but has there been any updates done?

Also, would it be possible to backup the configs for the hosts and reinstall XS from scratch, then restore configs?

@NerdyDad To my knowledge, from the time it was working, last Thursday/Friday, until I walked in the door yesterday morning and found issues, there had been no changes. I'm positive no updates have been done.

With regards to the backups, I'm sure I could try that. Do you have a link handy with a procedure for that, by any chance?

Also, have you tried shutting both down and bringing up Xen2, since its the pool master? Maybe Xen1 is trying to take over, thinking that Xen2 is down.

That's the last thing I'd tried before posting here. I couldn't bring Xen2 out of maintenance mode, nor reconnect storage.

Just lost my 31 day streak working on Christmas. Finally done. Merry Christmas to all and to all a good night.

We use Cisco Any Connect that authenticates against AD, but is not tied to any kind of GPS and it works for us just fine. Except for deployment, I see no need in using GPS.

If we use GPS for anything, it's with RADIUS for our wireless network. That works in one location but not the other. And this is only because both locations have different wireless systems and in how each system implements RADIUS and authenticates a laptop against an OU.

@scottalanmiller said in Can't connect CentOS 7 to network:

Why CentOS on laptops in the first place? That's the least laptop friendly Linux OS I can think of.

I am wanting to build out a network for my house with as minimal cost as possible while also being secure. This laptop I was wanting to use for NextCloud while having another laptop for ldap and another for PLEX.

I know that you're going to suggest putting it on a server with XenServer and run each installation as a VM. I have Dell PowerEdge 1950 that I could use, but I don't want to draw that much power and the thing is too noisy to have in the house. It gets too hot for it in the garage.

Have any suggestions? Maybe I could use a Dell Optiplex 380 desktop for either XS or bare-metal CentOS?

I am also not getting any activity lights on the network card. Is this normal in Linux?

Well, that's even easier, it's a hardware problem. Nothing should ever effect the blinking lights.

Possibly a driver issue then?

While possible, it's unlikely. The only real exceptoin that comes to mind is Debian with certain closed-source Broadcom drivers. What kind of network card is it, and was it working before?

It used to work before as it was my first coming to this company. I later switched to a newer laptop and put this one in the back for storage.

driver: e1000e
version: 3.2.5-k
firmware-version: 0.12-1
bus-info: 0000:00:19.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no

An Intel e1000e should be fine. Any lights showing on the switch port? No lights on either end = no network.

No lights.

Well, we know where the problem is now, but I doubt you'll be able to change the network card in a laptop

Well crap. I guess I'll use this for a study machine to learn with. I have a few more laptops here that I haven't installed CentOS on yet. I'll test their cards before I install CentOS.
