[Samba] Problem to set up an samba server

[Sylvain Sécherre]

Hello everyone !

I try since two weeks to share a directory using samba.

The server is a Linux Manjaro (Arch) distribution, IP = 192.168.1.16. 
The shared directory is /data.

The clients are Linux Debian and Android. On the main Debian client, the 
mounted directory is /media/partage.

I want to share files (r+w) without any identification on every devices 
of the local network.

Here is my /etc/samba/smb.conf file on the server:

[global]
    workgroup = WORKGROUP
    server string = sylvain-serv
    security = user
    hosts allow = 192.168. 127.
    load printers = no
    printing = bsd
    printcap name = /dev/null
    disable spoolss = yes
    invalid users = root
    usershare allow guests = yes
    map to guest = bad user
    log file = /var/log/samba/%m.log
    max log size = 50
    dns proxy = no

[data]
    comment = Data
    path = /data
    force user = sylvain
    force group = sylvain
    public = yes
    guest ok = yes
    read only = no
    browseable = yes

The mount command on the client (mount -t cifs //192.168.1.16/data 
/media/partage -o guest) is successful, but when I try to list (ls) the 
mounted directory, I am told that the permission is not given. Here is 
the mtab line :

//192.168.1.16/data /media/partage cifs 
rw,relatime,vers=3.1.1,sec=none,cache=strict,uid=0,noforceuid,gid=0,noforcegid,addr=192.168.1.16,file_mode=0755,dir_mode=0755,soft,nounix,serverino,mapposix,rsize=4194304,wsize=4194304,bsize=1048576,echo_interval=60,actimeo=1 
0 0

I have no network problem, I use to connect to the server in ssh. I 
tried to stop iptables and fail2ban on both server and client without 
success. Here is a nmap dialog:

# nmap 192.168.1.16
Starting Nmap 7.80 ( https://nmap.org ) at 2022-11-03 15:33 CET
Nmap scan report for minus.home (192.168.1.16)
Host is up (0.035s latency).
Not shown: 993 filtered ports
PORT     STATE  SERVICE

80/tcp   closed http
139/tcp  open   netbios-ssn
443/tcp  closed https
445/tcp  open   microsoft-ds
3306/tcp closed mysql

But when I look at the log files (/var/log/samba) there is no entry 
except the start of the daemons (smb and nmb).

Here is another issue:

# smbclient -NL 192.168.1.16
Anonymous login successful

     Sharename       Type      Comment
     ---------       ----      -------
SMB1 disabled -- no workgroup available

No samba server seems to be running.


Here is a ls -l in the /media directory of the client:

- before mounting :

     drwxrwxr-x  2 root root 4096 20 oct.  16:22 partage

- after mounting :

     drwxr-xr-x  2 root root    0  2 nov.  15:39 partage


The same on the server:

drwxrwxr-x   2 root root  4096  2 nov.  15:39 data


The rights of the file in the server shared directory (/data):

-rw-rw-r-- 1 root root     7 23 oct.  13:24  test.txt

I am near a nervous breakdown... I don't know what to do.

Anyone can help me ?
