Filesys::SmbClient(3) 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 length 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, acquired 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

  • chown
  • chmod
  • open_print_job
  • telldir
  • lseekdir

This module come with some scripts:
t/*.t
Just for check that this module is ok :-)
smb2www-2.cgi
