(Visual FoxPro) SFTP Get/Set File Permission

Demonstrates how to set the permissions of a file on the SFTP server

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

LOCAL loSftp
LOCAL lcHostname
LOCAL lnPort
LOCAL lnSuccess
LOCAL lnIsHandle
LOCAL lnFollowLinks
LOCAL lnPermVal

* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loSftp = CreateObject('Chilkat_9_5_0.SFtp')

* Connect to the SSH/SFTP server.  
lcHostname = "sftp.example.com"
lnPort = 22
lnSuccess = loSftp.Connect(lcHostname,lnPort)
IF (lnSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* Authenticate with the SSH server.  Chilkat SFTP supports
* both password-based authenication as well as public-key
* authentication.  This example uses password authenication.
lnSuccess = loSftp.AuthenticatePw("myLogin","myPassword")
IF (lnSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* After authenticating, the SFTP subsystem must be initialized:
lnSuccess = loSftp.InitializeSftp()
IF (lnSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* Get the file permissions for the "hamlet.xml" file on the server.
* The hamlet.xml file is located in the qa_data directory found under the HOME directory of the SSH user account.
* We are passing the remote file path (we are not passing a file handle returned by a previous call to OpenFile).
lnIsHandle = 0
lnFollowLinks = 1
lnPermVal = loSftp.GetFilePermissions("qa_data/hamlet.xml",lnFollowLinks,lnIsHandle)
IF (lnPermVal < 0) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

* Note: Filesystem permissions on Linux/Unix/MacOSX are typically written in octal (POSIX file permissions).  For example 0644 is octal.
* To convert to decimal: octal 644 = 6*8^2 + 4*8 + 4 = 420 (decimal)
* 
* The server may return a permissions value (in octal) such as 100644.
* The "100" indicates the file type, such as regular file or directory. 

* Show the decimal value of the permissions
? "decimal permissions value: " + STR(lnPermVal)

* To set the file permissions, pass the integer value.
* Let's change the permissions to 0664, which is 6*8^2 + 6*8 + 4 = 436 (decimal)
lnSuccess = loSftp.SetPermissions("qa_data/hamlet.xml",lnIsHandle,436)
IF (lnSuccess <> 1) THEN
    ? loSftp.LastErrorText
    RELEASE loSftp
    CANCEL
ENDIF

? "Success."

RELEASE loSftp
