There are two moments when you can mount a Windows share: Before you log in, and after you log in. Here are both examples:
Server name: fs Share name: install User: usr1 Password: pwd1 Local mountpoint: mnt Local user: ubuntuuser1
If you are a sudoer (or root), do the followinr
sudo smbmount //fs/install /mnt -o user=usr1 -p password:pwd1
Note that you need to be a sudoer.
If you want the share to be mounted for all users before anyone logs in, do the following:
Edit the /etc/fstab and add the line:
//fs/install /mnt cifs guest,uid=1000,iocharset=utf8 0 0
//fs/install /mnt cifs username=usr1,password=pwd1,iocharset=utf8,sec=ntlm 0 0
It would be wise to store the credentials elsewhere, since the 'fstab' file is readable by everyone.
Create ~/.smbcredentials
username=usr1 password=pwd1
//fs/install /mnt cifs credentials=/home/ubuntuuser1/.smbcredentials,iocharset=utf8,sec=ntlm 0 0
For special permissions (like chmod), you will need to provice a uid or gid parameter to the share's options
//fs/install /mnt cifs uid=ubuntuuser1,credentials=/home/ubuntuuser1/.smbcredentials,iocharset=utf8,sec=ntlm 0 0
