Mobile hotspot w/ IPSec VPN

Sysadmin - Fri, 09/21/2018 - 23:48

I have a remote user with a medical imaging device he takes to various locations. I wanted to look into getting him something that can provide a mobile internet connection and supports IPSec VPN tunnels so he can send the images back to the main office. Don't want to deal with software based tunnel for this as the device is pretty locked down and we can't really install anything on the device itself, so I want to deal with this with appropriate hardware.

Anyone have a recommendation on cost effective hardware for this purpose? A friend pointed me towards the Cradlepoint IBR1100. I wanted 2 ports so we could hook up the medical device and a laptop as well. Was interested in seeing if anyone has an opinion on Cradlepoint (never used them before) or any competing products.

Thanks in advance for feedback!

Game day tomorrow. I'm so lost.

Sysadmin - Fri, 09/21/2018 - 23:40

Gotta pull some SQL stunts tomorrow, I'm not that good. I suck at MS SQL but I can make it happen. I don't have to work but I am. No dumb bosses, no dumb expectations, I can phone it in, but I won't. More than one department depends on me making this right.

We don't talk about this much but it needs said; Sometimes you have to make it happen, no matter your pay, title or rank. Whether that's valued in your company is another discussion.

When it gets down to brass tacks, IT makes it happen. Other departments are equally important but IT pulls the trigger, nothing happens without our say. Want to argue that? Give me your compute device and tell me again.

Wish me luck. I have a NASA-style checklist to pull this off.

Large scale MariaDB galera cluster

Sysadmin - Fri, 09/21/2018 - 22:47

We currently run 9 mysql database servers that contain around a TB of total data with databases ranging from under 1gb to about 60gb. There are normally between 4000-5000 concurrent connections to each server. I currently run a MariaDB galera cluster for a much smaller internal database and was curious if it would be possible to combine all 9 production databases into 1 giant cluster, or if that is even a good idea. Any input one way or another is appreciated.

Foreman for one-time bare metal provisioning

Sysadmin - Fri, 09/21/2018 - 21:32

We currently deploy Ubuntu-based machines using a manual OS install process followed by Ansible playbooks to automatically configure them. We would like to further automate the process, and I am looking into Foreman/Katello because I think it will let me accomplish the following:

  • PXE boot and install Ubuntu on LUKS-encrypted disks
  • Pull variables for those machines from an external source (maybe?)
  • Automatically run Ansible playbooks to finish the configuration
  • Mirror (and freeze) apt and pip repos to control which packages/versions are available

The catch is, these systems won't be on our network very often, so ongoing monitoring and configuration enforcement isn't really something we're looking for. I'm still researching how exactly the different components of Foreman work, but I'm concerned about ending up with client computers out there forever trying to talk to a server they can't find, or leaving a lot of extra components behind (i.e., VNC servers still running and exposing ports when we don't ever need to connect to them). Is this a valid concern, or is it configurable enough that we can only use what we need? Is there something else that would better suit those goals?

PSA: Digicert OCSP server timeouts causing random SSL/TLS failures

Sysadmin - Fri, 09/21/2018 - 21:12

Digicert's OCSP server ( is very slow in responding to about 1% of requests today, which is causing various SSL/TLS clients, including browsers, to timeout and SSL/TLS negotiation to fail. We first saw it in Firefox connecting to a major US financial website to throw an SEC_ERROR_UNKNOWN_ISSUER error page, but we've had sporadic failures across everything all day. So if you're having random cert failures today ... yeah.

List effective permissions on shared folders

Sysadmin - Fri, 09/21/2018 - 19:47

The newly appointed DPO has asked IT to provide and maintain a list of all shared folders on our network for GDPR compliance, with each folder showing AD users read/write permissions.
We manage folder permissions by setting a Read group and a Change group for each folder and populating the two groups with users, so I cannot just list folder permissions but I have to dig into the groups (there are nested groups with "list content" rights as well). I managed to do it via a combination of powershell and excel magic but it's been a royal pain in the ass and by the time I had finished it it was already outdated.
I'm looking for software that can read effective rights on all Shared Folder on our file servers and give an exportable list of folders+users.
Google suggested Netwrix Auditor and Gold Finger. Any experience/advice?

DHCP scope and Windows Server question | Win 2016

Sysadmin - Fri, 09/21/2018 - 18:56

Hello everyone,

I have setup our domain controller, currently only one computer on it for testing but shortly we will move over the rest (30 computers). However, I had a thought.

Currently our DC and backup DC are on static IPs of and, however the scope on domain DHCP server is for .100 to .200.. meaning the two servers themselves are outside of their own DHCP scope.

This is fine for the moment as I currently have a basic router with DHCP in the building currently serving the IPs to all the computers.. however, when I turn that router off will I have issues? Do I need to make a new scope to include these static IPs, or just change them into the currently existing scope or will it be fine as it is?

Thank you.

Exchange issue, could use some advice please

Sysadmin - Fri, 09/21/2018 - 18:09

We are currently running a cobbled together, held together by hope and spit Exchange 2007 server.

Today, I installed Exchange 2013, SP1, and after fighting with it most of the day I got it to install completely.

I have done no configuration at all, it just was installed on a server that is on our domain. After getting it installed, I shut down the server and will be coming in on Sunday to do follow up work, and then next week will begin migrating mailboxes over to the new environment.

However, in the brief window that the server was online, 2 of the 3 users still in the building got a security certificate error. I shut down the server, and have instructed the users to log out and log back in, or possibly restart their machines.

Is it possible that, even though the configuration hasn't been completed, and that the new server isn't handling mail at all, that it could be interfering with Outlook for a few users?

Her event logs just show an Outlook crash. Good times.
