How to change SAMBA default port on centos?

Question

I need to change the port numbers of samba. Our ISP is blocking the ports 445 and 139. So I need to run samba in a different port.

Solution

Edit smb.conf and find a line like this,

smb ports = 445 139

change this default port to

smb ports = 2222 2000

Then restart samba server. Now samba server should be listening on the new ports that you have mentioned.

N.B. : Use port number above 1024 as these are reserved for system purpose.
