Mount SMB/CIFS share at boot in CentOS 7.

Mounting a Windows (CIFS) file share in CentOS 7 has changed a little when using a Windows domain to authenticate.

First, you need to have the cifs-util package installed. This will allow you to mount cifs/smb filesystems.

The syntax in the /etc/fstab has not changed, but the way the credential options are stored for domains is a little different. I use a hidden file that is read only to store the Windows credentials.


//winserver/sharename /mntpoint cifs credentials=/usr/local/etc/.myfile,iocharset=utf8,file_mode=0774,dir_mode=0774 0 0

Here is the change. In the past, I was able to specify the domain with the username in the credential file like so:


Now, the domain needs to be specified on its own line like so:


Windows Remote Process Kill

Ever need to kill a process on a remote Windows computer that you can’t login to and the user is not there? Taskkill can help. I am not sure when this utility was introduced, but I would think it is on Windows 7. I did this from a Windows 8.1 machine.

You can do it by PID:

taskkill /S computernameORipaddress /u username /PID pidnumber

Or executable image name:

taskkill /S computernameORipaddress /u username /FI “IMAGENAME eq imagename”

Here is an example. This kills Outlook on a computer with an IP address of using the Administrator account:

C:\>taskkill /S /u Administrator /FI “IMAGENAME eq outlook.exe”
Type the password for administrator:********

SUCCESS: The process with PID 2576 has been terminated.

Exchange 2010 Mailbox Recovery

Restore the database files to a location with enough space to hold the entire database and its logs. I created a full system (bare metal) backup using Windows Server Backup. I recovered using the following options:
Select Recovery Type: Applications
Select Application: Exchange
Specify Recovery Options: Recover to another location
Under Confirmation, I presume you would be able to choose the database you want to restore. I only had one, so it was selected.

This will restore the database and logs to the location you specified. I suspect the process will be very similar for other backup solutions that support Exchange.

Check database State:

[PS] >eseutil /mh ‘E:\WSBRecovery\Mailbox Database 1234567890\Mailbox Database 1234567890.edb’

Filter output for the State:

[PS] >eseutil /mh ‘E:\WSBRecovery\Mailbox Database 1234567890\Mailbox Database 1234567890.edb’ | findstr “State”

Check status of the logs:

[PS] >eseutil /ml ‘E:\WSBRecovery\Mailbox Database 1234567890\E00’

Replay the logs and update the database. The /l option is the log location, and the /d is the database location.:

[PS] >eseutil /r E00 /i /l ‘E:\WSBRecovery\Mailbox Database 1234567890’ /d ‘E:\WSBRecovery\Mailbox Database 1234567890’

Check the State again. It should be Clean Shutdown now.:

[PS] >eseutil /mh ‘E:\WSBRecovery\Mailbox Database 1234567890\Mailbox Database 1234567890.edb’ | findstr “State”

If the State still say Dirty Shutdown, you can try to repair the database. However, this should be your last resort:

[PS] >eseutil /p ‘E:\WSBRecovery\Mailbox Database 1234567890\Mailbox Database 1234567890.edb’

Create a new recovery database using the restored clean database:

[PS] >New-MailboxDatabase RecoveryDatabase -Server MY-EXCHG01 -Recovery:$true -EdbFilePath ‘E:\WSBRecovery\Mailbox Database 1234567890\Mailbox Database 1234567890.edb’ -LogFolderPath ‘E:\WSBRecovery\Mailbox Database 1234567890’

Mount the recovery database:

[PS] >Mount-Database RecoveryDatabase

If you have an old recovery database open, you may need to dismount the old and delete it first. Not sure if that is applicable for all Exchange versions, but this was the case in Exchange Server 2010 Standard version:

[PS] >Dismount-Database ‘MY-EXCHG01 DB01 Recovery’
[PS] >Remove-MailboxDatabase -Identity ‘MY-EXCHG01 DB01 Recovery’

Check for the mailboxes in the recovered database:

[PS] >Get-Mailboxstatistics -Database RecoveryDatabase

Restore the database to a Restore folder, so the lost messages can be copied from the Restore folder. Once the lost messages are moved out of the Restore folder, the Restore folder can be deleted.

[PS] >Restore-Mailbox -Identity “JGZ Test” -RecoveryDatabase RecoveryDatabase -RecoveryMailbox “JGZ Test” -TargetFolder Restore

If you are restoring a mailbox for one user and putting it in another users mailbox, you need to make sure you have the order right.
Identity is the mailbox you are going to be restoring to (target), and the RecoveryMailbox is the mailbox you are restoring (source).

[PS] >Restore-Mailbox -Identity “put-IT-here” -RecoveryDatabase RecoveryDatabase -RecoveryMailbox “get-IT-here” -TargetFolder Restore


Exchange Management Shell Commands (work in progress)

This is more a reference for myself:

I covered the basics of message tracking in:

Database size:

Get-MailboxDatabase -Status | Select Name,DatabaseSize

PublicFolderDatabase size:

Get-PublicFolderDatabase -Status | Select Name,DatabaseSize

To determine role assignments:


Create a recovery mailbox:

New-MailboxDatabase -Recovery -Name “Recovery DB Name” -Server EXCHANGESERVERNAME

To check mailbox stats:

Get-MailboxDatabase -Status | Format-List Mame,DatabaseSize,AvailableNewMailboxSpace

Delete a mailbox database. Once removed, you can delete the files from the file system.:

Remove-MailboxDatabase -Identity “Recovery DB Name”

The right way to create a recovery database:

New-MailboxDatabase -Recovery -Name “Recovery DB Name” -Server EXCHANGESERVERNAME -EdbFilePath Drive:\Directory\Filename.edb -LogFolderPath Drive:\Directory

Move a mailbox:
You can use the canonical name of the object with the mailbox ( DOMAIN.LOCAL/OU/OU/Name ) to move from EMS.

Note: You may need to enable inheritance. This can be dome from the ADUC. Access the Properties for the user and click on Security tab. If it is not visible, you need to enable your ADUC view for Advanced Features. Once on the Security tab, click Advanced, and then down in the bottom left click “Enable inheritance”. This is on a Windows 2012 R2 domain controller. It might a little different dialog on older versions of Windows server.

[PS] >’DOMAIN.LOCAL/TahityOU/SurfingOU/Cool Dude’ | New-MoveRequest -TargetDatabase ‘My Exchange Database’

DisplayName Status TotalMailboxSize TotalArchiveSize PercentCompl
———– —— —————- —————- ————
Cool Dude Queued 5 B (5 bytes) 0

Check the status of all move requests:

[PS] >Get-MoveRequest

Check Cool Dude’s move request:

[PS] >Get-MoveRequest -Identity ‘cooldude@tahiti.surfing’

Nice, but what do I do to get all those canonical names?
The following will give you all the canonical names for all objects in your domain. From a domain controller, fire up powershell:

PS > Get-AdUser -Properties CanonicalName -Filter ‘*’ | Select CanonicalName

I am sure there is a better way to do this, but this will give some output that will have the CanonicalName and Exchange mail server for an object. You can work with this output to come with a list that of objects that need to be moved.

PS > Get-AdUser -Properties CanonicalName,msExchHomeServerName -Filter ‘*’ | Select CanonicalName,msExchHomeServerName | Format-List

I have noticed that sometimes when I move a mailbox from one database to another and then I display mailbox statistics, I will have two different results for the same mailbox. To find these, you need you use Get-MailboxStatistics and filter for MailboxState of SoftDeleted:

PS > Get-MailboxStatistics -server servername | Select DisplayName,DisconnectReason,Database | findstr “SoftDeleted”

And then to remove the SoftDeleted version of the mailbox:

PS > Remove-StoreMailbox -Identity “mailboxidentity” -Database “mailboxdatabase” -MailboxState SoftDeleted

This will create a Send Connector for use in your LAN. In my case, it is a linux server. Create a Send Connector:

New-SendConnector -Name ‘Some Name’ -Usage ‘Internal’ -AddressSpaces ‘SMTP:hostORdomainname;1’ -IsScopedConnector $false -DNSRoutingEnabled $false -SmartHosts ‘[aaa.bbb.ccc.ddd]’ -SmartHostAuthMechanism ‘None’ -UseExternalDNSServersEnabled $false -SourceTransportServers ‘MY-EXCHG01’

Create a new mail contact:

New-MailContact -ExternalEmailAddress ‘SMTP:mycontact@email.address’ -Name ‘mycontact’ -Alias ‘mycontact’ -FirstName ‘My’ -Initials ‘MC’ -LastName ‘Contact’ -OrganizationalUnit ‘DOMAIN.LOCAL/OU/OU’

To change a setting for a connector:

[PS] C:\>Get-ReceiveConnector “MYEXSERVER\Non-Exchange Relay Support” -ProtocolLoggingLevel Verbose

A note on connector logging:
The connector logs are stored on the Transport Hub server in the ExchangeInstallPath\TransportRoles/Logs/ProtocolLog/SmtpReceive for the receive connectors, and ExchangeInstallPath\TransportRoles/Logs/ProtocolLog/SmtpSend for the send connectors.

Also, in a mixed version environment, the connector may have to be “upgraded” to support logging. I was not able to turn on the the logging for my old Exchange 2003 connectors. Upgrading basically consists of deleting and creating again.

To view basic information about a mailbox:

[PS] C:\>Get-Mailbox “mailboxname

To view detailed information about a mailbox:

[PS] C:\>Get-Mailbox “mailboxname” | Format-List

To filter that list:

[PS] C:\>Get-Mailbox “mailboxname” | Format-List properties

[PS] C:\>Get-Mailbox “mailboxname” | Select properties

To see mailbox usage, number of items, etc:

[PS] C:\>Get-MailboxStatistics “mailboxname

Which you can filter as well:

[PS] C:\>Get-MailboxStatistics “mailboxname” | Format-List properties

[PS] C:\>Get-MailboxStatistics “mailboxname” | Select properties

View mailboxes and sort them by size:

[PS] C:\>Get-MailboxStatistics | Select DisplayName,TotalItemSize,LastLoggedOnUserAccount,LastLogonTime | Sort-Object -Property TotalItemSize

This works too:

[PS] C:\>Get-MailboxStatistics -Server servername | Select DisplayName,ItemCount,TotalItemSize | Sort TotalItemSize

To view mailbox logon information:

[PS] C:\>Get-LogonStatistics ‘mailboxname’

To view who has access to a mailbox:

[PS] C:\>Get-MailboxPermission “mailboxname

Add mailbox permission:

[PS] C:\>Add-MailboxPermission -Identity ‘mailboxidentity‘ -User ‘domain\username‘ -AccessRights ‘FullAccess’

Move a mailbox:

[PS] C:\>’cntouseraccount’ | New-MoveRequest -TargetDatabase ‘databasename


[PS] C:\>’MY.DOMAIN/MYOU/my name’ | New-MoveRequest -TargetDatabase ‘MYEXCHANGEDB’

To check move request statuses:

[PS] C:\>Get-MoveRequest

For more detail, like how far a move has progressed:

[PS] C:\>Get-MoveRequestStatistics -IncludeReport

To set the bad item limit for a mailbox that has partially been transferred:

[PS] C:\>Set-MoveRequest -Identity “my name” -BadItemLimit numberofitems

To resume a failed mailbox move:

[PS] C:\>Resume-MoveRequest ‘my name’

To move a mailbox that has some corrupted items (in this case, one):

[PS] C:\>’MY.DOMAIN/MYOU/my name’ | New-MoveRequest -BadItemLimit 1 -TargetDatabase ‘MYEXCHANGEDB’

If you have a lot of issues:

[PS] C:\>’MY.DOMAIN/MYOU/my name’ | New-MoveRequest -BadItemLimit 100 -AcceptLargeDataLoss -TargetDatabase ‘MYEXCHANGEDB’

Note: these items will then not be migrated over the new location.

To count the number of items in some output use Measure-Object:

This more of a PowerShell tip than an EMS tip, but it is good to know when using EMS.

[PS] C:\>Get-Mailbox | Measure-Object

Count : 124
Average :
Sum :
Maximum :
Minimum :
Property :

Queue notes:

Check queues:

[PS] C:\>Get-Message -Server servername

Remove a message from a queue:

[PS] C:\>Remove-Message -Identity messageidentity

[PS] C:\>Write-Output Output something.

To count the number message received on a day:

[PS] C:\>Get-MessageTrackingLog -Start “mm/dd/yyyy 00:00″ -End “mm/dd/yyyy 23:59″ -EventID RECEIVE | Measure-Object

To find mailbox sizes and sort by size:

[PS] C:\>Get-MailboxStatistics -Server servername | Select DisplayName,TotalItemSize | Sort TotalItemSize

To remove automapping. Or how to grant access to a mailbox and not enable AutoMapping like the UI does:

[PS} C:\>Add-MailboxPermission -Identity mailboxname -User username -AccessRight FullAccess -InheritanceType All -Automapping $false

How to restore Outlook views

To restore your Outlook views to the default, you just need to start Outlook with a cleanviews switch. In Windows 7 and up, it is easiest to let search do the work for you. Just type in the command:

outlook.exe /cleanviews

There are quite a few other switches available for Outlook 2010 and Outlook 2013.

I have used the /safe switch many times in the past for older versions when I have trouble with Outlook crashing.

VMWare ESXi and HP DL380 Heap issue.

I was getting the following message when I would try to start up a VM on an HP DL380.

Heap globalCartel-1 already at its maximum size of 7869288. Cannot expand. Could not start VMX: msg.vmk.status.VMK_NO_MEMORY

The machine had plenty of memory and seemed to operating fine for currently running VMs. When I brought up the direct console on the machine, there was screen full of the following:

/bin/sh: can’t fork

I could not enter any commands other than “exit.” I could log in and out, and that is about it.

In VMWare KB article 2085618, it acknowledged the issue with the HP specific image and the HP AMS driver.

Updated the HP AMS driver per VMWare KB article 2085618.

To determine version running:

esxcli software vib list | grep ams

SQLite and fail2ban

OS: CentOS7

I wanted to see exactly how and where the fail2ban IP addresses were stored. Looking in the fail2ban.conf file, I found the following:

dbfile = /var/lib/fail2ban/fail2ban.sqlite3

So, I did a little research to try to find out how access the database.

To open or connect to the database:

# sqlite3 /var/lib/fail2ban/fail2ban.sqlite3

To list all the tables in the database:

sqlite> .tables
bans fail2banDb jails logs

To query a table:

sqlite> SELECT * FROM logs;

Another table:

sqlite> SELECT * FROM bans;

To disconnect from the database:

sqlite> .quit

CentOS – Convert PST to MBOX

To convert a PST file that was created by exporting email from Outlook in Windows, you can use libpst. It is in the CentOS 7 base repository.

# yum install libpst

Then, to convert a PST to MBOX:

# readpst my.pst

This will create an mbox file for each of the folders, including sub-folders if they were exported in Outlook.

GPG basic commands
