Help configuring Samba

[freezr]

Ok folks...

 

This very setup was fixed and made working at my job. I tested from the new M$ Terminal while connected to the LAN of my office, extremely satisfied I returned to home and when I connected the HC4 to my router, the "systemd smbd.service" didn't work again (event though at my workplace I rebooted for testing purpose the board several time and Samba had been woking all the time).

 

The Office LAN is most likely managed by a Win Server and is on 192.160.0.X, at home I am connected to a Comcast Cable Router on 10.0.0.X...

 

This the error I get from systemd:

My setup doesn't change the default "smbd.conf' but it recalls another configuration with:

 

config file = /etc/samba/smb-local.conf

 

I added that line to the very first section of the default "smbd.conf":

 

[global]

config file = /etc/samba/smb-local.conf

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
   workgroup = WORKGROUP

# server string is the equivalent of the NT Description field
   server string = %h server (Samba, Ubuntu)

 

All my main configurations go under the "smb-local.conf", this is the setup has been taken from my current "OMSC/RPI2" Samba configuration:

 

[global]

# If you require a fully custom smb.conf create smb-local.conf instead of editing smb.conf so your
# configuration will not be overwritten by samba upgrades. You can use smb.conf as a template by
# copying it to smb-local.conf then removing the config file line below in the new file. If you only
# need to add some additional shares see smb-shares.conf below for a simpler way to do this.


    workgroup = YOUR-HOME-CLOUD
    security=user
    follow symlinks = yes
    wide links = no
    unix extensions = no
    lock directory = /var/cache/samba
    load printers = no
    printing = bsd
    printcap name = /dev/null
    disable spoolss = yes
    log level = 1
    map to guest = bad user
    usershare template share = automount template


##############


    read raw = Yes
    write raw = Yes
    strict locking = no
    min receivefile size = 16384
    use sendfile = true
    aio read size = 2048
    aio write size = 2048
    socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=131072 SO_SNDBUF=131072


##  FreeBSD Changes


    ntlm auth = yes
    server max protocol = SMB3_11
    server min protocol = NT1
    client max protocol = SMB3_11
    client min protocol = NT1


[droid]
    browsable = no
    read only = yes
    valid users = droid
    path = /home/YOUR-HC4-USER
    comment = Droid Home Directory


[automount template]
    browseable = yes
    -valid = no
    valid users = YOUR-HC4-USER
    path = %P
    hide files = /$RECYCLE.BIN/System Volume Information/desktop.ini/thumbs.db/

# Add custom shares in smb-shares.conf instead of editing smb.conf so they will not be
# overwritten by samba updates. You can only add new shares to smb-shares.conf, not change
# the default shares or global options. If you need full control see smb-local.conf above.

include = /etc/samba/smb-shares.conf

 

Users are handled by:

 

include = /etc/samba/smb-shares.conf

 

This is an example how my "/etc/samba/smb-shares.conf" is composed and is taken by my documentation, but matches my current setup:

 

[public]
  comment =Public Storage
  path = /srv/samba/public
  valid users = @users
  force group = users
  create mask = 0660
  directory mask = 0771
  read only = no


[MyUSER]
    browsable = yes
    read only = no
    valid users = YOUR-HC4-USER, MyUSER
    path = /srv/samba/MyUSER
    comment = MyUSER Folder
    force group = users
    locking = no
    create mask = 0765
    directory mask = 0765

 

Of course if I remove from "smbd.conf" this line:

 

config file = /etc/samba/smb-local.conf

 

The systemd service doesn't fail... But with my configuration "testparm -s" doesn't fail either...

 

$ testparm -s
Load smb config files from /etc/samba/smb.conf
Loaded services file OK.

[global]
        config file = /etc/samba/smb-local.conf
        log file = /var/log/samba/log.%m
        logging = file
        map to guest = Bad User
        max log size = 1000
        obey pam restrictions = Yes
        pam password change = Yes
        panic action = /usr/share/samba/panic-action %d
        passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

        passwd program = /usr/bin/passwd %u
        server role = standalone server
        server string = %h server (Samba, Ubuntu)
        unix password sync = Yes
        usershare allow guests = Yes
        idmap config * : backend = tdb


[printers]
        browseable = No
        comment = All Printers
        create mask = 0700
        path = /var/spool/samba
        printable = Yes


[print$]
        comment = Printer Drivers
        path = /var/lib/samba/printers

 

Thanks! 🙏🙏🙏

I found the culprit and was this line:

 

lock directory = /var/cache/samba

 

For testing I created "/var/cache/samba/locks" but it didn't work either...

 

This link says it safe using default setup:

 

https://www.linuxtopia.org/online_books/network_administration_guides/using_samba_book/ch05_05_11.html

 

Therefore for the moment I commented it to make the smbd,service working...
