This section contains information related to Samba, software that makes it possible to share files between Linux and Windows systems.

samba

Browsing of Windows shares (also known as SMB browsing) fails on Fedora Core 4test1 systems that have the standard firewall configured. This is most easily noticed in the failure of Nautilus to display shares. The failure is due to the firewall disrupting the broadcast mode of SMB browsing, which is Samba's default setting. There are two workarounds:

  • Configure a WINS server on the network, and set the "wins server" option in smb.conf to the address of the WINS server.
  • Disable the firewall

Warning

Depending on your system and network configurations, disabling the firewall can greatly increase the chance of your system being attacked and compromised. Make sure you fully understand the risks before undertaking this step.
