Just got home, fairly shitty day...but this one sums it up....

customer has a problem with a printer on a Mac, trying to fix it by removing and reinstalling etc, all the usual stuff. My test print works fine to it from word, but he's trying to print an excel sheet. Not got a clue (and I still hate macs) so tell him I'm going to do some research and is that ok. He says yes....so I look into it, find a few possible solutions, ring him back "Nope, you've run out of time, I have things to do now." - well....it's obviously not that ephin important then is it.

/rant.

Mac users are the worst

I was thinking about writing a beginners guide to LVM, but it's already been done so often already that I'll spare you all from my literary, lack of, skills. Instead, I'll link to a few places that I use for reference, outside of the man pages.

HowtoForge Walks you through all the basics, rather long.
The Geek Diary Has a shorter version with more graphics, but doesn't cover as much.
How to Geek Includes a handy chart of which options are available for PV, VG, and LV. Also covers snapshots succinctly.

One thing none of those mention that I've found very handy at times, lvm is it's own command. If you're stuck in a recovery shell, no internet access, and can't remember exactly what command(s) and options you need to use. Fire up lvm, and type 'help'. Once you figure out which command(s) are needed 'help command' should get you going. Frankly, it reminds me of how OpenVMS operated, which I never really liked. Great for when you don't even have man pages available tho.

That's it for now. I'll try to update this if anyone has more questions.

I have a few friends and family members that I use facebook to actually communicate with, lol.

Why Facebook Why not any other tool.

Because it's the only way they all communicate

@siringo said in Remote Desktop to Fedora 28?:

So I've setup my old laptop with Fedora v28 workstation.

What can I use to, (for want of the correct Linux terminology), RDP into my Fedora laptop when I'm out in the field?

Not being command line savvy, it will need to be a GUI interface.

Thanks.

If you want RDP, install xrdp, start the service and enable it to run at boot.

sudo dnf -y install xrdp
sudo systemctl start xrdp
sudo systemctl enable xrdp
sudo firewall-cmd --permanent --add-port=3389/tcp
sudo firewall-cmd --reload

Will install it, start the service, enable the service at boot time, and open the local firewall port for it.

@gjacobse vey few things are more rewarding than giving a helping hand. We all have to keep up the fight against things like IPODs.

Or getting a good FFS from @JaredBusch when needed.

Doing both of those things is so valuable, and not done in so many other places.

So this is somewhat for my own future reference, as it was a pita to track down online.

Scenario: User had been delegated access to another user account. Now does not need or want to see the email from the other user account.

I found the actual solution here: https://www.msoutlook.info/question/673

Add-MailboxPermission -Identity <shared mailbox alias> -User <your mailbox alias> -AccessRights FullAccess -InheritanceType All -Automapping $false

This was the only way to remove the shared mailbox from the user account when delegation was setup on the server. All the other articles say to remove the account from Outlook, that doesn't exist.

Cursing a former MSP. This AD we inherited has no security groups, just user permissions set for everything. It hurts us.

You'll need a VM on your XenServer/XCP-ng server to act as a proxy. I'm assuming you're starting with an up to date Fedora Server install. You'll also need a Wasabi account, bucket, key and secret.

sudo dnf -y install s3fs-fuse
sudo echo "Your_Key:Your_Secret" > /root/.passwd-s3fs
sudo chmod 600 /root/.passwd-s3fs
sudo mkdir /backup
sudo echo "s3fs#mybucket /backup fuse _netdev,allow_other,use_path_request_style,url=https://s3.wasabisys.com 0 0" >> /etc/fstab
sudo dnf -y install nfs-utils
sudo systemctl enable --now rpcbind
sudo echo "/backup ipofserver(rw,fsid=1000)" > /etc/exports
sudo systemctl enable --now nfs-server
sudo firewall-cmd --permanent --add-service=nfs
sudo firewall-cmd --reload

Now you just mount the NFS directory from Xen Orchestra like normal. If you need help with that, go talk to @DustinB3403.

My mount point currently shows 256T Avail.

/sigh Surprise! Watching new applications fail to install on old servers that won't be upgraded or patched because of $reasons which are beyond my control.

No point in wasting your time on it.

Don't have a choice. Well, I guess I do -- find a new job

Speaking of which, I just got home from an interview that went very well today.

@xrobau said in Changes at Sangoma:

@travisdh1 You still seem to be hung up on the RAID concept of parity. Truly, honestly, that's not how ZFS works. I cross my heart. It works on copies of data. Literal, exact, copies of the data.

Unfortunately, THIS is where the 'ZFS Can't expand a volume' problem comes into play. Because the location of those copies (on the physical spindles) is made by hashing the size and number of volumes in a zraid (I'm kinda simplifying here, but work with me!)

So if a ZRAID2 has 5 spindles, that means that a copy of block 1 of the zpool will be placed on spindle 1 at sector 10, 3 at sector 100 and spindle 5 at sector 500. The location of that doesn't need to be looked up, because it can be calculated.

The 'expansion' problem comes about because if you add another spindle to that ZRAID2, suddenly block 1 would be on spindle 1 at sector 10, spindle 3 at sector 500 and spindle 6 at sector 1000 (or whatever). So the location of the data would be wrong, and everything falls apart.

(Now, this is actually wrong, and there IS an index, but, that's advanced stuff, and this is good enough for you to get the idea).

Does that make more sense?

Not at all, because you are describing RAID 5/6. There is nothing special or different here.

@magicmarker said in Linux OS advice for building a SAM-SD:

I just want to mention that the KVM Hypervisor does take more than Linux basic knowledge. After @JaredBusch and @scottalanmiller recommended KVM on Fedora for the SAM-SD OS I have been playing with the KVM Hypervisor on a minimal Fedora install. I was able to successfully get a working KVM Hypervisor running. I realize that I've been very spoiled with the ESXi Hypervisor. I will require a more GUI based Hypervisor setup. I played around with the virt-manager which is a nice alternative to the cli for novice Linux users. There is still too much for me to learn with KVM and I never really did find instructions that really spell it out for me. I'm trying not to use VMware ESXi. I'm going to re-visit Hyper-V 2016 standalone with a Fedora Server (with desktop) VM to be my NFS file server. I'm open to any advice or words of encouragement to re-direct my focus back to the KVM Hypervisor.

You couldn't find any good guides to KVM? We should see about writing one here.

I CAN SEE THIS, GUYS.

We all figured that after Mangocon, keeping any secrets from @ChrisL is just silly.

I see. Just single disk systems. You could do that with Nucs.

Exactly, you could go with the cheapest possible hardware solution that your hypervisor could run on. Not even care if a single host were to die. Just introduce a new device if one does go down.

GET OUT OF TOWN! Are you serious?

Ha ya, we were roommates all through college.

Little did I know that when I said this place felt like home in the introduce yourself thread, I was being literal!

Should I go over chkrootkit, rkhunter, or something else? Obviously have to at least mention these, I don't know if I'll have time to get in-depth with one or not, guess I'll take thoughts on weather I should make the time to do that or not as well?

The original FTC article, and ZDnet/Jack Schofield's take.

Basically, forcing users to change passwords often is terrible security on the human side. I've always thought as much, but rarely get actual evidence to back it up.
