The default value for simultaneous connections to a Samba share is unlimited. This is represented by the value of zero. To control the amount of allowed concurrent connections, the Samba directive "max connections" in /etc/samba/smb.conf should be set. Any clients connecting when the maximum has been reached will receive a message telling them to try again later.

The example below illustrates how to limit a Samba share to 20 concurrent connections:

[training]
path = /feu
public = yes
browsable = yes
writable = yes
valid users = @students
max connections = 20

After modifying the /etc/samba/smb.conf file, restart the smb service:

service smb restart
