Recommendations for powershell profile

As i showed in my post about creation of powershell profile you can add into profile your own frequently used functions.

I recommend to name them with permanent prefix. For example i create all my functions as moguy-cdp, moguy-esxi and so on.

In this case you don’t need to remember the name of your function to run, just start typing as moguy… and autocompletion will show you all your functions.

for example:

function moguy-vms

{

Get-VMHost | Get-VM | Select-Object Name, PowerState, NumCpu, MemoryMB, VMhost, @{N="Datastore";E={Get-Datastore -vm $_}}, UsedSpaceGB, ProvisionedSpaceGB, @{Name='ToolsVersion';Expression={$_.Guest.ToolsVersion}}, @{Name=’VMHostVersion’;Expression={$_.VMHost.Version}},Version, @{N="IP Address";E={@($_.guest.IPAddress[0])}},@{Name=’Cluster’;Expression={$_.VMHost.Parent}}, @{N="PortGroup";E={Get-VirtualPortGroup -VM $_}}, @{N="owner1";E={$_.customfields.item("owner1")}} | Export-Csv

How configure ssh_config for windows openssh client, for example for PubkeyAcceptedKeyTypes=+ssh-dss

Since win10 you have openssh ssh.exe in

C:\Windows\System32\OpenSSH

So to use passwordless ssh connection you maybe need to provide ssh.exe “PubkeyAcceptedKeyTypes=+ssh-dss”

For this you can create ssh_config file anywhere (for example in c:\users\yourname\.ssh near your id_dsa private key file) with only one line:

PubkeyAcceptedKeyTypes=+ssh-dss

so now you can:

ssh yourname@1.1.1.1 -F "c:\users\yourname\.ssh\ssh_config"

where 1.1.1.1 for example your ssh server, san_switch, HPE virtual connect manager, nimble storage and so on

ps
the same is true for openssh server installed from home site on win2016 server
only ssh.exe file will be in
“C:\Program Files\OpenSSH-Win64” (by default installation)… Read the rest

how properly enter into maintenance mode on Exchange2016/2013 DAG

Let’s assume that we have

ex01.itforce.local and ex02.itforce.local Exchange 2016 servers in DAG cluster. We need to install new CU on this cluster without downtime. (assumed that all CAS, smtp protocols are properly loadbalanced). So we need:

  1. at first disable all workloads/switch to maintenance mode on the node ex01,
  2. install CU on ex01,
  3. reboot ex01
  4. exit from maintenance mode on ex01
  5. enter into maintenance mode on ex02
  6. install CU on ex02,
  7. reboot ex02
  8. exit from maintenance mode on ex02
  9. equally spread workload on both nodes again
#goto ex01
#run in elevated mode powershell for exchange

#prepare smtp transport:
Set-ServerComponentState ex01
