Get-ADPermission -identity distributiongroupname | where {($_.ExtendedRights -like “*Send-As*”) -and ($_.IsInherited -eq $false) -and -not ($_.User -like “NT AUTHORITY\SELF”)} | FT -Wrap

It’s essentially the same command. Instead of piping the mailbox object to the Get-ADPermission cmdlet, here you’re telling the Get-ADPermission cmdlet the name of the distribution group you want to find who has permissions for.

Get-Mailbox -identity mailboxname | Get-ADPermission | where {($_.ExtendedRights -like “*Send-As*”) -and ($_.IsInherited -eq $false) -and -not ($_.User -like “NT AUTHORITY\SELF”)} | FT -Wrap

You can also pipe in all mailboxes or a server or database to find out send-as permissions on all mailboxes as follows

Get-Mailbox | Get-ADPermission | where {($_.ExtendedRights -like “*Send-As*”) -and ($_.IsInherited -eq $false) -and -not ($_.User -like “NT AUTHORITY\SELF”)} | FT -Wrap

Get-Mailbox -Server servername | Get-ADPermission | where {($_.ExtendedRights -like “*Send-As*”) -and ($_.IsInherited -eq $false) -and -not ($_.User -like “NT AUTHORITY\SELF”)} | FT -Wrap

Find the users session index

show vpn-sessiondb | include (username)

The index field is what you’re looking for. Once you have this you can log that particular session off by using the following command.

vpn-sessiondb logoff index XXXX

where XXXX is the index number.

show vpn-sessiondb remote

You can of course use modifiers to filter only the text you’re interested in. For example

show vpn-sessiondb remote | include (Username|Duration)

This will give you the username and duration of the session.

You can also get a summary of all the connections as follows

show vpn-sessiondb summary

get-QADUser -Locked

tar zxvf filename.tar.gz

z = Gunzip(uncompress) it before extracting, used on file ending in .tar.gz or .tgz
x = Extract the contents of the TAR file
v = Verbose – display contents as it is tarring or extracting
f = Filename to follow

Note: If the file does not have “.gz” extension that means its already uncompressed and one has to just extract it using “tar xvf” command.

This is a two step command to extract and untar the file.

gunzip filename.tar.gz

tar xvf filename.tar

$ssh -D 8888 username@remotesshserver

This command tells your machine to create a tunnel to the remote ssh server and create a proxy on your local machine at port 8888 for you to use.

Now all you need to do is configure your browser to use this proxy.

Server: localhost or 127.0.0.1
Port: 8888

Although using this proxy through firefox will secure your web traffic, it will not hide your DNS queries. With SOCKS 5 in Firefox you can specify which side of the proxy handles DNS lookups. This can be done by setting network.proxy.socks_remote_dns = true in about:config.

Even when you run the Exchange Management Shell on your exchange server, you’re essentially creating a powershell remoting session. The following steps take place in the background when you click the EMS icon:

You can set up implicit remoting from any maching using powershell v2. This imports the commands from your exchange server to your local powershell session so you don’t need any Exchange tools installed.

First we create a session using the New-PSSession cmdlet:

$s = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri http://<CAS FQDN>/PowerShell/ -Authentication Kerberos

Then, import the session using the Import-PSSession cmdlet:

Import-PSSession $s

The Exchange Management Shell commands are now imported into the local PowerShell session.

You could use the same method to setup a scheduled task from your machine to run a commands on your exchange server.
