AutoFS and Mounting Network Shares Cont.

May 4, 2022 By JeffTechs

In a previous article, I went over how to setup a network share using the traditional client/server approach. It’s a great way to reduce unwanted file duplication, and share items in a secure manner. But, what if we have a lot of NFS shares and we don’t want to clog up our /etc/fstab or we […]

Adding Pronouns to Active Directory

March 21, 2022 By JeffTechs

More companies are adopting pronouns with digital identities. It’s not just social media platforms; C-Suite and staff are looking to add pronouns to their Outlook and even their Windows login. While it may be easy enough to do this for a few users, updating an entire organization with hundreds (or thousands) of people is incredibly […]

Windows Time Service: Check and change NTP Servers

March 11, 2022 By JeffTechs

It’s easy to forget how crucial time synchronization is across a network/domain until it stops working. After you setup your Domain controller and pick a time zone, it should all just work–and it typically does. However, if you manage Windows Servers for long enough, this is probably going to be something you have to mess […]

Mounting FileSystems and AutoFS in CentOS/RHEL 8

March 10, 2022 By JeffTechs

I haven’t worked in an environment yet that didn’t share some sort of files over the network. Even some end users are trained to setup network drives and OneDrive/SharePoint syncing. Having multiple copies of the same file can be a dangerous thing (not talking about back-ups), and network sharing can help everyone keep a focused […]

Manage Chrome through Windows Server GPO

March 10, 2022 By JeffTechs

I’ve been remiss with keeping up with my technical articles. I’ve devoted a lot of time to studying for the RHCSA, and last week, I passed on the first try. Feels amazing to achieve that goal; and no better way to celebrate a Linux achievement, than to write an article about Windows Server :-). Web […]

Windows Global Catalog Server and Powershell

December 28, 2021 By JeffTechs

I’ve been working on the RHCSA, an Exchange migration and updating an Active Directory forest for the last few months, so I haven’t been writing as much as I’d like to. There’s quite a bit of new information I’ve picked up recently, but this was something I wanted to touch base on before (potentially) writing […]

New System’s Administrator/Engineer Script

September 30, 2021 By JeffTechs

A few months ago I started looking for a new job. I wasn’t excited to start over again, but I wanted more challenges and technologies to work on. I remember starting my first few technology jobs, and thinking how difficult it was to find documentation for the servers and networks–I was even left to figure […]

Windows Server DNS: Failover and Forwarding

September 29, 2021 By JeffTechs

DNS is pretty crucial in a domain environment. If you pull up DNS on your domain controller(s), you can see a listing of, well, a lot of different stuff–PC names to start in DNS > Forward Lookup Zones > domain name. There’s also reverse lookup zones, possibly even mail server records and even more. DNS […]

Subinterfaces: The Artist formerly know as Router-On-A-Stick

September 10, 2021 By JeffTechs

I wrote an article not too long ago about VLAN tagging from a post Cisco perspective. Since I covered the layer 2 aspect, I figured why not complete the setup and show how to configure Virtual Interfaces. I have a SonicWall handy, so I am going to demonstrate with that device. Besides routers/firewalls behaving vastly […]

VLANs: Tagged, Untagged and PVIDs

September 10, 2021 By JeffTechs

Coming from a Cisco background, VLANs were pretty straight forward–especially from a switching perspective. Once you get your Router On a Stick setup, you decide which ports are access and which are trunks. It looks a little something like this:   Interface FastEthernet 0/1 switchport mode access switchport access vlan 20 Now, port 0/1 is […]
