SFTP/FTP Project uploader

This program uploads files and directories from your local machine to a remote server using either SFTP or FTP, based on the protocol specified in the configuration file.

Download here: mProjectUploader.zip

Features

  • Supports both SFTP (Secure Shell) and FTP (File Transfer Protocol).
  • Automatically handles directory creation on the remote server.
  • Skip files or directories based on configurable patterns.
  • Multiple overwrite policies, including:
    • skipAll: Skip all existing files.
    • overwriteOlder: Overwrite files only if the remote file is older.
    • overwriteDifferentSize: Overwrite files if their sizes differ.
    • overwriteAll: Overwrite all files.
    • OverwriteKeepTrack: Overwrite only if the file content has changed (based on checksum).
  • Tracks skipped, changed, and uploaded files.

Usage Instructions

1. Prepare the Configuration File

The program uses an XML configuration file (e.g., config.xml) to define its behavior. Below is an example of the configuration file:

<config>
  <protocol>sftp</protocol> <!-- Use 'sftp' or 'ftp' -->
  <host>example.com</host>
  <port>22</port> <!-- Default: 22 for SFTP, 21 for FTP -->
  <username>your_username</username>
  <password>your_password</password>
  <destinationPath>/remote/destination/folder</destinationPath>
  <overwritePolicy>OverwriteKeepTrack</overwritePolicy>
  <skipList>
    <file>*.tmp</file> <!-- Skip all .tmp files -->
    <file>*.log</file> <!-- Skip all .log files -->
    <directory>node_modules</directory> <!-- Skip this directory -->
  </skipList>
  <checksums>
    <!-- Checksum tracking for OverwriteKeepTrack -->
    <file path="local/path/to/file1.txt" checksum="abc123" />
    <file path="local/path/to/file2.txt" checksum="def456" />
  </checksums>
</config>

2. Run the Program

Run the program using the following command:

SftpUploader.exe <config_file_path>

For example:

SftpUploader.exe config.xml

If no configuration file path is provided, the program looks for config.xml in the current directory.

Configuration Parameters

General Settings

  • <protocol>: Specifies the transfer protocol. Options:
    • sftp: Secure Shell File Transfer Protocol.
    • ftp: File Transfer Protocol.
  • <host>: Remote server hostname or IP address.
  • <port>: Server port (default: 22 for SFTP, 21 for FTP).
  • <username>: Username for authentication.
  • <password>: Password for authentication.
  • <destinationPath>: Remote directory path(s). Multiple <destinationPath> entries are supported.

File Handling

  • <overwritePolicy>: Determines how existing files are handled. Options:
    • skipAll: Skip all files that exist on the server.
    • overwriteOlder: Overwrite files only if the remote file is older.
    • overwriteDifferentSize: Overwrite files if their sizes differ.
    • overwriteAll: Overwrite all files.
    • OverwriteKeepTrack: Overwrite files only if their content has changed. Uses checksums stored in the checksums section.

Skip List

  • <skipList>: Allows you to exclude specific files or directories from processing.
    • <file>: Wildcard patterns for files to skip (e.g., *.log, *.tmp).
    • <directory>: Names of directories to skip.

Checksum Tracking

  • <checksums>: Used with OverwriteKeepTrack to track file changes.
    • <file>: Each entry contains the local file path and its checksum.

Features Based on Protocol

SFTP

  • Fully secure file transfer using SSH.
  • Handles recursive directory creation via the CreateDirectoryRecursively method.

FTP

  • Classic FTP protocol with directory and file handling.
  • Uses System.Net.FtpWebRequest for file uploads and directory creation.

Example Scenarios

1. Upload All Files

<overwritePolicy>overwriteAll</overwritePolicy>

This policy overwrites all files on the remote server.

2. Skip All Files

<overwritePolicy>skipAll</overwritePolicy>

This policy skips all files that already exist on the server.

3. Upload Only Changed Files

<overwritePolicy>OverwriteKeepTrack</overwritePolicy>

This policy compares checksums and uploads only files that have changed.

4. Skip Specific Files and Folders

<skipList>
  <file>*.tmp</file>
  <directory>bin</directory>
</skipList>

This configuration skips all .tmp files and the bin directory.

Statistics

At the end of execution, the program outputs statistics about the operation:

  • Total Files: The total number of files considered.
  • Skipped Files: The number of files skipped based on the policy or skip list.
  • Changed Files: The number of files identified as changed (only for OverwriteKeepTrack).
  • Uploaded Files: The number of files successfully uploaded.

Example output:

Processing destination: /remote/destination/folder
Total Files: 50, Skipped Files: 20, Changed Files: 5, Uploaded Files: 25

Error Handling

  • If the configuration file is missing or invalid, the program will display an error and exit.
  • Errors during file uploads or directory creation are logged to the console but do not stop the program.

Dependencies

  • SFTP: Renci.SshNet library for secure file transfer.
  • FTP: Built-in System.Net.FtpWebRequest.

Troubleshooting

  1. Missing Configuration File: Ensure the configuration file exists at the specified path and follows the correct format.
  2. Protocol Not Supported: Verify the <protocol> field in the configuration file is set to ftp or sftp.
  3. Authentication Issues: Check the host, username, and password values in the configuration file.
  4. Skipped Files: Review the <skipList> and <overwritePolicy> settings to ensure they align with your expectations.

Outlook automapped mailboxes – dealing with design flaws with VBA

Sending an email from a automapped (usually shared) mailboxes – I don’t know why, because everyone hates that – has two issues: 1. user needs to change From address every time from his primary mailbox to the correct one, 2. Sent emails are saved in primary mailbox Sent folder, not in the folder of the shared mailbox.

We want Outlook to use From address based on selected folder in Outlook and also, we want this email to be saved in correct Sent folder. This issue has been present ever since and MS approach to first spit out registry hacks and then enable setting some parameters – only for each Mailbox separately (!) to deal with issue #2 is unacceptable. As usually we need to make some hacks to fix that.

Private WithEvents objInspectors As Outlook.Inspectors
Private WithEvents sentItems As Outlook.Items

Function findAddressOfCurrentFolder()
        Set selectedFolder = Application.ActiveExplorer.CurrentFolder
        
        ' Initialize the Outlook NameSpace
        Set namespace = Application.GetNamespace("MAPI")
        Set Stores = namespace.Stores
        storeDisplayName = selectedFolder.Parent.Store.DisplayName
        Set storeRecipient = Session.CreateRecipient(storeDisplayName)

        If storeRecipient.AddressEntry.Type = "EX" Then
            findAddressOfCurrentFolder = storeRecipient.AddressEntry.GetExchangeUser.PrimarySmtpAddress
            
        End If
        If storeRecipient.AddressEntry.Type = "SMTP" Then
            findAddressOfCurrentFolder = storeRecipient.Address
        End If
End Function

Private Sub objInspectors_NewInspector(ByVal Inspector As Inspector)

  If TypeName(Inspector.CurrentItem) = "MailItem" Then
     storeSMTPAddress = findAddressOfCurrentFolder
     If storeSMTPAddress <> "" Then 
        Inspector.CurrentItem.SentOnBehalfOfName = storeSMTPAddress
     End If
  End If
End Sub

We just fixed the first issue! One more to go.

Function isSentItemsFolder(ByVal Folder As Outlook.Folder)
 sentFolderNames = Array("Sent Items", "Odeslaná pošta", "Odoslaná pošta")
 For i = LBound(sentFolderNames) To UBound(sentFolderNames)
        If sentFolderNames(i) = Folder.Name Then
            isSentItemsFolder = True
            Exit Function
        End If
    Next i
 isSentItemsFolder = False
End Function
Private Sub sentItems_ItemAdd(ByVal Item As Object)
 Dim correctSentFolder As Outlook.Folder
 Dim myNamespace As Outlook.namespace
 Dim mailbox As Outlook.MAPIFolder
 
    If TypeName(Item) = "MailItem" Then     'If Item is a MailItem
        If Item.SentOnBehalfOfName <> Session.Accounts.Item(1).CurrentUser Then   'And if Item is Sent on Behalf of the users own inbox
            'Move the email into the Sent Items folder for the inbox in question
            Set myNamespace = Application.GetNamespace("MAPI")
            Set myRecipient = GetNamespace("MAPI").CreateRecipient(Item.SentOnBehalfOfName)
            myRecipient.Resolve
            If myRecipient.Resolved Then
                'Set sentFolder = GetNamespace("MAPI").GetSharedDefaultFolder(myRecipient, olFolderSentMail)
                Set mailbox = myNamespace.GetSharedDefaultFolder(myRecipient, olFolderInbox).Parent
                For Each Folder In mailbox.Folders
                    If Folder.DefaultItemType = olMailItem Then
                     If (isSentItemsFolder(Folder)) Then
                        Set correctSentFolder = Folder
                    End If
                 End If
                Next Folder
            End If
            If Not correctSentFolder Is Nothing Then Item.Move correctSentFolder
        End If
        
    End If
End Sub

And that’s the fix for the second issue – saving items in proper folder. There is no way to get Sent folder of a shared/automapped mailbox. We need to iterate and check for its names. If English is used “Sent Items” is sufficient. For other languages, we need to add translations (function isSentItemsFolder).

Pull users from AD

I needed:

  • users from AD with specific OU
  • non disabled
  • filter by department
  • manager details
  • last logon time and other details

For pulling active (non disabled) users belonging to specific group along with their managers name into CSV, I made following powershell script. Output is then loaded into excel and send automatically to managers for approval. Department “x” means a special user which will be omitted.

$FileName="c:\somepath\somefile.txt"

if (Test-Path $FileName) 
{
  Remove-Item $FileName
}

$fileEncoding = "Default"

Out-File -encoding $fileEncoding $FileName

$dn = (Get-ADGroup 'Some group').DistinguishedName
$users = Get-ADUser -Filter " memberof -RecursiveMatch '$dn'" -Properties $properties

Foreach ($User in $Users)
{
 if ($user.Enabled -and ($user.Department -ne "x")) {      
  $userName=$user.UserPrincipalName
  $ou=$user.DistinguishedName.split(',OU=')[5]
  $man=$user.Manager
  $mail=$user.mail
 
  if ($man -ne $null) {	  
	$mgrUsr=(Get-ADUser $man -Properties UserPrincipalName,DisplayName,mail)
	$mngr=$mgrUsr.UserPrincipalName + ";" +$mgrUsr.mail + ";" + $mgrUsr.DisplayName
  } else {
	$mngr=";;"  
  }
  ($user.UserPrincipalName + ";" +  $user.cn + ";" + $user.LastLogonDate + ";" + $ou + ";" + ";" + $mngr  + ";" + $user.Department)  | Out-File -encoding $fileEncoding $FileName -Append 
  
 } 
}
