What Are You Doing Right Now

Cuz I eats me spinach....

Just got back from Applebee's.

I wondered why I'm feeling hot. It's just ticking over 11am and it's already almost 37C. Ah crap, today is going to be a stinker... if only going by the stench from my under arms which is assaulting my nasal cavities.

becoming a plumber....

Installing Zimbra on CentOS 7 and Seafile on another instance. Next project will be a jump box (possibly local)

Got my Plex server on C@C working!

Did anyone have issues with the site over the past, say ~4 hours but excluding the past hour? I got online and found that the stats for the site had dropped to zero, which was impossible since I was using it myself. Also unlikely as we had thousands of views per hour solid for days, no breaks, and suddenly went to three hours of actual zero (zero, not near zero) including while I was using the site. I restarted the process and numbers shot right back to where they had been. So I am guessing that we had a logging failure (system could no longer write to disk or something) but am hoping that we didn't have a database issue. The DB was not restarted and is healthy now. So just wondering if anyone had an issue with the site during that window or if it was purely a record keeping issue.
No one has posted anything about seeing issues. So I am guessing that all is clear.

I had some issues but it seems to be okay now...

@thanksajdotcom what did the issues look like? Problems posting?

Notifications and unread numbers not updating when you open the thread that's unread or the notifications, etc.

That would make sense, if logging was failing those things would fail too. The site was working fine, but not recording the views, when I signed in. So clearly some things were working. I'm hoping that posting was working. I've not come across a post that I know was posted during the window, but that would be easy to miss.

Jump box? curious....
About to head out to a remote office,.. just put my phone on DnD...

That's the first thing that we built on CloudatCost. We had a self-hosted Jump box in our Mississauga datacenter which is scheduled for decom. So we needed a new one, the timing was perfect. Since you typically do not want a Jump box in a datacenter with your other production workloads (at least I prefer not to unless you are a single location facility) it was a perfect use for CloudatCost which was new to us.
Using a Dev1 is perfect for that. You'd need to be a massive organization for that to not be plenty of horsepower. We could make do with nearly half the resources of the Dev1 for that.
We used CentOS 7. Only option packages are the LogStash Forwarder for ELK, SysStat, htop and, of course, Fail2Ban which is super critical on a Jump box.

So a jump box is basically a way to get from the internet into the admin side of your intranet? I guess I'm not sure I understand what a jump box actually is.

Technically a Jump box is not related to Internet vs. other network. It is a term for a remote access proxy aggregation. In the UNIX world, which is really what we are implying here, it is an SSH proxy 99% of the time. But in theory we could have it as a remote X2Go station. But, you can assume we mean an SSH proxy. In the Windows world they are less common, but still common and well known, and almost exclusively are RDP proxies.
The purpose of a Jump box is a combination of access, access control and security. A Jump box, sometimes called a Jump station, is a gateway for access to other systems. As we are hosted across the world in many datacenters, we use one on the Internet, but lots of companies use them internally and they have nothing but private IPs.
How we use a Jump box in the UNIX world, and you can easily extrapolate for Windows, is to make a very light and lean machine with absolutely no services except for SSH. (Obviously we have normal monitoring on there.... log monitoring and stuff for security.) This system allows any of our UNIX users to log into it. It is heavily locked down, none of the normal user accounts that would have admin access have it there. Even the admins are end users on the Jump box. It is common to log actions heavily on the Jump box to for audit purposes.
The Jump box contains things like the private keys for the users so that they can easily log into the actual servers quickly and easily. It is from the Jump box that the admins or even just UNIX users do all of their work. You always log into it first and from there into everything else. The Jump box would hold your "Screen" sessions.
The normal UNIX servers get the public keys of the Jump box so you can log in without further authentication. This makes working on many servers quick and easy while being super secure. (You can always add more security where needed.) It also allows those machines to lock their SSH access to just the Jump server(s) for added security.
It's very worth it for UNIX users. Makes working in UNIX so much easier.

Thanks for the explanation, I assumed about half of that but you, as usual, went into far greater depth. Wouldn't having the private keys on this server be an issue? Or is it because it is so locked down and none of the other servers will accept connection coming from anywhere else that this is less of a concern?

It's a handy thing to have. I've used it in the past as a way to access my Linux servers via SSH in case I wasn't on a machine that had Pertino on it. I download PuTTY/KiTTY quick, ssh to the jump server via the hostname I setup publicly and boom, I have access to all my internal SSH-accessible devices. And since I have root as the username for all and keys setup, it's super easy.
