NAME ^

Filesys::SmbClient - Interface for access Samba filesystem with libsmclient.so

SYNOPSIS ^

  use POSIX;
  use Filesys::SmbClient;
  
  my $smb = new Filesys::SmbClient(username  => "alian",
                                   password  => "speed",
                                   workgroup => "alian",
                                   debug     => 10);
  
  # Read a file
  my $fd = $smb->open("smb://jupiter/doc/general.css", '0666');
  while (defined(my $l= $smb->read($fd,50))) {print $l; }
  $smb->close(fd);
  
  # ...

See section EXAMPLE for others scripts.

DESCRIPTION ^

Provide interface to access routine defined in libsmbclient.so provided with Samba.

Since 3.0 release of this package, you need a least samba-3.0.2. For prior release of Samba, use Filesys::SmbClient version 1.x.

For old and 2.x release, this library is available on Samba source, but is not build by default. Do "make bin/libsmbclient.so" in sources directory of Samba to build this libraries. Then copy source/include/libsmbclient.h to /usr/local/samba/include and source/bin/libsmbclient.so to /usr/local/samba/lib before install this module.

If you want to use filehandle with this module, you need Perl 5.6 or later.

When a path is used, his scheme is :

  smb://server/share/rep/doc

FONCTIONS ^

new %hash

Init connection Hash can have this keys:

  • username
  • password
  • workgroup
  • debug
  • flags : See set_flag

Return instance of Filesys::SmbClient on succes, die with error else.

Example:

  my $smb = new Filesys::SmbClient(username  => "alian",
                                   password  => "speed", 
                                   workgroup => "alian",
                                   debug     => 10);
set_flag

Set flag for smb connection. See _SMBCCTX->flags in libsmclient.h Flag can be:

SMB_CTX_FLAG_USE_KERBEROS
SMB_CTX_FLAG_FALLBACK_AFTER_KERBEROS
SMBCCTX_FLAG_NO_AUTO_ANONYMOUS_LOGON

Tie Filesys::SmbClient filehandle

This didn't work before 5.005_64. Why, I don't know. When you have tied a filehandle with Filesys::SmbClient, you can call classic methods for filehandle: print, printf, seek, syswrite, getc, open, close, read. See perldoc for usage.

Example:

  local *FD;
  tie(*FD, 'Filesys::SmbClient');
  open(FD,"smb://jupiter/doc/test")
    or print "Can't open file:", $!, "\n";
  while(<FD>) { print $_; }
  close(FD);

or

  local *FD;
  tie(*FD, 'Filesys::SmbClient');
  open(FD,">smb://jupiter/doc/test")
    or print "Can't create file:", $!, "\n";
  print FD "Samba test","\n";
  printf FD "%s", "And that work !\n";
  close(FD);

Directory

mkdir FILENAME, MODE

Create directory $fname with permissions set to $mode. Return 1 on success, else 0 is return and errno and $! is set.

Example:

  $smb->mkdir("smb://jupiter/doc/toto",'0666') 
    or print "Error mkdir: ", $!, "\n";
rmdir FILENAME

Erase directory $fname. Return 1 on success, else 0 is return and errno and $! is set. ($fname must be empty, else see rmdir_recurse).

Example:

  $smb->rmdir("smb://jupiter/doc/toto")
    or print "Error rmdir: ", $!, "\n";
rmdir_recurse FILENAME

Erase directory $fname. Return 1 on success, else 0 is return and errno and $! is set. Il $fname is not empty, all files and dir will be deleted.

Example:

  $smb->rmdir_recurse("smb://jupiter/doc/toto")
    or print "Error rmdir_recurse: ", $!, "\n";
opendir FILENAME

Open directory $fname. Return file descriptor on succes, else 0 is return and $! is set.

readdir FILEHANDLE

Read a directory. In a list context, return the full content of the directory $fd, else return next element. Each elem is a name of a directory or files.

Return undef at end of directory.

Example:

  my $fd = $smb->opendir("smb://jupiter/doc");
  foreach my $n ($smb->readdir($fd)) {print $n,"\n";}
  close($fd);
readdir_struct FILEHANDLE

Read a directory. In a list context, return the full content of the directory FILEHANDLE, else return next element. Each element is a ref to an array with type, name and comment. Type can be :

SMBC_WORKGROUP
SMBC_SERVER
SMBC_FILE_SHARE
SMBC_PRINTER_SHARE
SMBC_COMMS_SHARE
SMBC_IPC_SHARE
SMBC_DIR
SMBC_FILE
SMBC_LINK

Return undef at end of directory.

Example:

  my $fd = $smb->opendir("smb://jupiter/doc");
  while (my $f = $smb->readdir_struct($fd)) {
    if ($f->[0] == SMBC_DIR) {print "Directory ",$f->[1],"\n";}
    elsif ($f->[0] == SMBC_FILE) {print "File ",$f->[1],"\n";}
    # ...
  }
  close($fd);
closedir FILEHANDLE

Close directory $fd.

Files

stat FILENAME

Stat a file FILENAME. Return a list with info on success, else an empty list is return and $! is set.

List is made with:

  • device
  • inode
  • protection
  • number of hard links
  • user ID of owner
  • group ID of owner
  • device type (if inode device)
  • total size, in bytes
  • blocksize for filesystem I/O
  • number of blocks allocated
  • time of last access
  • time of last modification
  • time of last change

Example:

  my @tab = $smb->stat("smb://jupiter/doc/tata");
  if ($#tab == 0) { print "Erreur in stat:", $!, "\n"; }
  else {
    for (10..12) {$tab[$_] = localtime($tab[$_]);}
    print join("\n",@tab);
  }
fstat FILEHANDLE

Like stat, but on a file handle

rename OLDNAME,NEWNAME

Changes the name of a file; an existing file NEWNAME will be clobbered. Returns true for success, false otherwise, with $! set.

Example:

  $smb->rename("smb://jupiter/doc/toto","smb://jupiter/doc/tata")
    or print "Can't rename file:", $!, "\n";
unlink FILENAME

Unlink FILENAME. Return 1 on success, else 0 is return and errno and $! is set.

Example:

  $smb->unlink("smb://jupiter/doc/test") 
    or print "Can't unlink file:", $!, "\n";
open FILENAME
open FILENAME, MODE

Open file $fname with perm $mode. Return file descriptor on success, else 0 is return and $! is set.

Example:

  my $fd = $smb->open("smb://jupiter/doc/test", 0666) 
    or print "Can't read file:", $!, "\n";
  
  my $fd = $smb->open(">smb://jupiter/doc/test", 0666) 
    or print "Can't create file:", $!, "\n";
  
  my $fd = $smb->open(">>smb://jupiter/doc/test", 0666) 
    or print "Can't append to file:", $!, "\n";
read FILEHANDLE
read FILEHANDLE, LENGTH

Read $count bytes of data on file descriptor $fd. It lenght is not set, 4096 bytes will be read.

Return buffer read on success, undef at end of file, -1 is return on error and $! is set.

FILEHANDLE must be open with open of this module.

write FILEHANDLE, $buf
write FILEHANDLE, @buf

Write $buf or @buf on file descriptor $fd. Return number of bytes wrote, else -1 is return and errno and $! is set.

Example:

  my $fd = $smb->open(">smb://jupiter/doc/test", 0666) 
    or print "Can't create file:", $!, "\n";
  $smb->write($fd, "A test of write call") 
    or print $!,"\n";
  $smb->close($fd);

FILEHANDLE must be open with open of this module.

seek FILEHANDLE, POS

Sets FILEHANDLE's position, just like the "fseek" call of "stdio". FILEHANDLE may be an expression whose value gives the name of the filehandle. The values for WHENCE is always SEEK_SET beacause others didn't work on libsmbclient.so

FILEHANDLE must be open with open of this module.

close FILEHANDLE

Close file FILEHANDLE. Return 0 on success, else -1 is return and errno and $! is set.

shutdown flag

A wrapper around `libsmbclient's `smbc_free_context'.

Close open files, release Samba connection, delete context, aquired during open_* calls.

Example:

    $smb->shutdown(0); # Gracefully close connection
    $sbm->shutdown(1); # Forcibly close files and connection

NOTE: shutdown(1) may cause complaints about talloc memory leaks, if there are currently no open files.

Print method

unlink_print_job PRINTER_URL, IDJOB

Remove job number IDJOB on printer PRINTER_URL

print_file DOCUMENT_URL, PRINTER_URL

Print file DOCUMENT_URL on PRINTER_URL

TODO ^

EXAMPLE ^

This module come with some scripts:

t/*.t

Just for check that this module is ok :-)

smb2www-2.cgi

A CGI interface with these features:

  • browse workgroup ,share, dir
  • read file
  • upload file
  • create directory
  • unlink file, directory
