We are trying to mount a windows share on a linux host. We are able to ping the windows host from the linux host. However the mount command fails with the error No route to host found. It appears there is a firewall issue for the ports required for mount point. We need ti inform the networkign team as to which ports need to be opened. Doing a google search seems to provide following list of ports
13, 137, 138, 139 and 445. However the question are

1) Do we need all these ports opened between the two hosts?
2) Are all these ports tcp or udp or both?

Thank you for any pointers/suggestions.

Thanks again

The Microsoft Knowledge Base explains how to avoid this issue, and the ports required for SMB/CIFS networking.

It has been a long time since I really worked on a Windows computer, but I am fairly sure the firewall should have some option along the lines of "Enable File and Printer Sharing" that would automatically open those ports for you.
