Instead of putting it all in a batch file, including your credentials
a safer way is to put an entry like this in /etc/fstab:

//192.168.2.96/public   /mounts/syno-public       cifs    credentials=/root/.smbcred,defaults,uid=<your username>,gid=<your username>,auto,users,exec,vers=3.0 0 0

i.e., where you use the "credentials=" option, store your credentials
in the file you identify in that option, and assign the file permissions
like this:

ls -l /root/.s*
-rw-------. 1 root root 36 Feb  5  2017 /root/.smbcred

which makes it root readable/writable only. much safer than putting
it all in a shellscript.

this is on Centos 7-up-to-date, using Samba 4.6.2.

the credentials file contents would be of the form:

username=<your windows username>
password=<your windows password>

Oh, and also, the "vers=3.0" forces SMB 3 protocol, which is MUCH less
full of holes than are the earlier versions. Depending on the flavor of
windows you're connecting to, you  may need to relax that to 2 instead
of 3. But don't go to version 1, Microsoft has (finally) deprecated it
as being too insecure for words.
