MacOS: zsh Terminal and other misc restore/configuration portability...



Summary:
I bought a new macbook pro and typical behavior is to use time machine to restore.  This method is perfectly acceptable 99% of the time.  Those that mess w/ kext, sudoers, and other jazz... not so much.  I originally did a time machine restore, but that brought over a mess of things that I quite frankly had forgotten about (I like to tinker) and that was unfair to my new macbook.  Needless to say, but I bricked my new macbook which led me to Konmari my setup.

Details:
Then there is the portability aspect of my terminal environment that I've been so lacking.  In combination w/ Dropbox, I'm able to move this stuff around and keep things in sync much easier now.

Basically restoring bash/zsh alias is a pain.  Modifying any of these things is also a hassle.  So I developed a shell script that will basically take files that exist in my Dropbox directory and symlink the original files back to Dropbox.

This way I can simply run this shell script on any new system and it'll restore my terminal environment as I like it.  I get the added benefit of making changes to these Dropbox configuration files and it'll automatically get synced w/ my other systems.  This way I don't have to maintain a sync of my environment configurations through some other method.

This same scheme could also be done through git as well, albeit, publicly.  Utilizing iCloud to sync Desktop and Documents "might" work as well.

Script:
The script is made for MacOS, but could be adapted for Linux.
It does the following as of this posting:
  • Symlinks SSH config files in your .ssh directory to dropbox.
  • Symlinks zsh plugins to your oh-my-zsh/plugins to dropbox.
  • Symlinks zsh themes to your oh-my-zsh/themes to dropbox.
  • Symlinks Cisco Anyconnect VPN profiles to dropbox.
  • Symlinks customsudo files to your /etc/sudoers.d to dropbox.
    • This one will do a visudo check to confirm your syntax is correct ONLY.
    • It is still possible to break sudo w/ a syntactically correct sudo file.
    • Remove this if you don't need it.  I simply use it to remove sshuttle's need for sudo.
  • Installs brew if not detected.
  • Installs oh-my-zsh if not detected.
I'll probably be fiddling w/ this for awhile, so you'll likely see modifications/updates on gist.

NSX-T: vCenter and NSX-T Inventory out of Sync (Hosts in vSphere not showing up in NSX-T)

Image
Summary: NSX-T loses synch w/ vCenter inventory, but statuses don't appear to show an issue.  Basically, you add a host to a vCenter cluster, NSX-T bits should start to automatically installing on new host.  Assuming you've created a Transport Node Profile and associated w/ the cluster.  The problem is that NSX-T doesn't see the new host and its link to the compute manager (vCenter) looks fine. Looks fine, Y U NO WORK!? So what's going on here?  This appears to affect NSX-T 2.5 and 2.5.1.  Cause is unknown. Workaround: Restart the cm-inventory service on each NSX-T mgmt/controller node using API or CLI. Details: If you were to query the status of the cm-inventory via API or CLI, you could query all 3 manager/controller nodes and get a status of running.  Even if the primary node associated w/ the VIP, if configured, is not necessarily in charge of inventory.  So you could restart the cm-inventory service till you are blue in the face and get nowhere be

MacOS: AnyConnect VPN client was unable to successfully verify the IP forwarding table modifications.

The VPN client was unable to successfully verify the IP forwarding table modification.  A VPN connection will not be established. Summary: I started running into issue utilizing Cisco AnyConnect on my Mac basically complaining about not able to overwrite IP forwarding tables.  This was on 4.6.x.  Since my VPN endpoints were not providing me w/ an updated client and w/ no access to Cisco Anyconnect downloads, my only option was to try openconnect.  It was totally worth it, here is why and how to set it up. PreReqs: Homebrew Installing OpenConnect: Launch MacOS Terminal brew install openconnect Getting VPN IP's/DNS Endpoints from AnyConnect: The information is typically located in your profile xml files located here: /opt/cisco/anyconnect/profile/somethingsomething.xml In the xml file, you are looking for "<HostAddress>typicallyaDNSName.com</HostAddress>" entry.  These are your VPN endpoints that you would need to pass to openconnect.

vCenter: Cluster Skip Quickstart Workflow via API

Image
Summary: Basically, whenever you reset vCenter, you might end up w/ a warning on a cluster running vSAN that's just annoying.  To circumvent, this from alerting, you need to disable quickstart.  Easy enough via UI, but API is a little weird here. Details: For one, code capture doesn't seem to understand this.  So no help there unfortunately.  Secondly, nothing named "quickstart" is in the API, so made this somewhat annoying to try and find.  Seems like someone had this question on the VMware communities forum 2 years ago w/ no answer.   Someone asked me internally, so I had to dig into it. Basically, two things: You can create a cluster w/ quick start disabled from the get go by passing a false boolean to a parameter named: "InHciWorkflow" via API/PowerCLI call Secondly, to "skip QuickStart" on an already created cluster, you can call a method called: "AbandonHciWorkflow" So yeah, you can see how "quickstart" and "HCIWorkfl
