$ smbclient -U samba -L samba

gives:

Enter MYGROUP\samba's password:

        Sharename       Type      Comment
        ---------       ----      -------
        myshare         Disk
        IPC$            IPC       IPC Service (file server)
Reconnecting with SMB1 for workgroup listing.

        Server               Comment

        Workgroup            Master
        ---------            -------

example.php is configured as follows:

$host = 'samba';
$user = 'samba';
$workgroup = '';
$password = 'samba';
$share = 'myshare';

$auth = new \Icewind\SMB\BasicAuth($user, $workgroup, $password);
$serverFactory = new \Icewind\SMB\ServerFactory();
$server = $serverFactory->createServer($host, $auth);
$shares = $server->listShares();
foreach ($shares as $s) {
        echo $s->getName() . "\n";
}

$share = $server->getShare($share);
$files = $share->dir('/');            // PHP hangs in this line forever!!!
foreach ($files as $file) {
        echo $file->getName() . "\n";
}

Output:

myshare

And then, example.php hangs forever. What is going wrong here? How to debug?

My OS is Alpine (Docker). PHP Version 7.2.12

I have the same problem. When executing

strace php example.php

the last lines are:

fstat(13, {st_mode=S_IFIFO|0600, st_size=0, ...}) = 0
fcntl(13, F_SETFD, FD_CLOEXEC)          = 0
close(15)                               = 0
fstat(14, {st_mode=S_IFIFO|0600, st_size=0, ...}) = 0
fcntl(14, F_SETFD, FD_CLOEXEC)          = 0
wait4(285, 0x7fff30d0d0a4, WNOHANG|WSTOPPED, NULL) = 0
wait4(285, 0x7fff30d0d174, WNOHANG|WSTOPPED, NULL) = 0
write(5, "\n", 1)                       = 1
read(6, "Try \"help\" to get a list of poss"..., 8192) = 47
read(6, "smb: \\> ", 8192)              = 8
read(6, "smb: \\> ", 16376)             = 8

This seems to be a wrong command submitted to smbclient so that smbclient goes into interactive mode.

What next?

Working with Alpine Linux and

$ smbclient --version
Version 4.8.12

Found it,

I had just installed smbclient in the Alpine image:

apk add samba-client

So, the smbclient was used by this repo and not libsmbclient-php.

Then I added phpsmbclient to the image in the Dockerfile:

RUN apk --update --virtual build-deps add --no-cache  \
        autoconf \
        make \
        gcc \
        g++ \
        gmp-dev \
    && apk add --no-cache \
        samba-client \
        samba-dev  \
    && pecl channel-update pecl.php.net \
    && pecl install smbclient  \
    && docker-php-ext-enable smbclient \
    && docker-php-source delete \
    && docker-php-ext-install -j16 gmp \
    && rm -rf /tmp/* \
    && apk del build-deps

Now the libsmbclient-php is selected and everything works like charm.

Issue can be closed. I'm happy.

So it seems like this problem only happens when this lib is using the smbclient executable instead of the extension?

Yes. This is what happened here.

Using the smbclient leads to the smbclientcommand line mode and then waits for input- forever :-(
