    Linux CIFS Client Guide Author: Steve French 01/03/07 Version 0.21 Preface The most recent version of this document is located at http://us1.samba.org/samba/ftp/cifs-cvs/linux-cifs-client-guide.odt and equivalently http://us1.samba.org/samba/ftp/cifs-cvs/linux-cifs-client-guide.pdf This is version 0.21 of the document. Feedback can be sent to [email protected] and/or to the author directly: [email protected] Thanks to Chris Cowan and Shirish Pargaonkar for valuable suggestions and corrections. Introduction A network filesytem provides access to files and directories on another computer as if they were on a locally attached disk. The 2.6 version of the Linux kernel introduced a new file system driver cifs.ko to mount to Windows and Samba servers and run demanding applications from those mounts. Although commonly used to mount to non-Linux servers, such as Windows, the cifs virtual file system client [cifs vfs] is optimized for Samba and servers which implement the CIFS POSIX extensions. CIFS is a great alternative to NFS and other network file systems in certain workloads. In earlier versions of Linux the only alternatives for accessing Linux or Windows servers were: ➢ using the smbclient tool, a user space application with ftp like semantics ➢ mounting with smbfs, a more limited smb client kernel filesystem driver which provided only partial POSIX semantics ➢ Installing nfs on the server, and mounting with Linux's nfs client (which does not have an oplock based cache consistency mechanism, and has a more limited security model).
