Chapter 10. File Access
ThinLinc supports accessing files on both Windows and Novell file servers.
10.1. Accessing Windows File Servers
10.1.1. Introduction
This chapter describes how to setup a ThinLinc server to access Windows file servers via the SMB/CIFS
protocol. CIFS is a modern version of SMB. In this document, we use the term CIFS, but the procedure
described in this documentation works for SMB servers as well.
CIFS is different from NFS in that CIFS mounts are per user, not per system. For example, with NFS, it’s
possible to mount all network file systems when the server boots. One NFS mount can be used by all
users on the system. With CIFS, each user must have their own mounts. Also, when mounting a CIFS file
system, the password of the user is usually required.
ThinLinc and many other UNIX applications requires that hard links are supported in the user’s home
directory. There are often other POSIX file system semantic requirements as well. This means that the
user’s home directories cannot be a mounted CIFS filesystem. The Linux CIFS client (smbfs) does not
support all POSIX file operations, such as hard links. The newer CIFS client (cifsfs) supports the CIFS
UNIX extensions, but few CIFS servers support this and this feature has not been tested with ThinLinc.
ThinLinc includes two utility programs for dealing with CIFS mounts: tl-mount-cifs and
tl-umount-all-cifs . These are described below.
The method described in this chapter mounts all CIFS shares below the directory ~/winshares. The
user’s CIFS home directory, if any, is mounted at ~/winshares/home.
10.1.2. Requirements
10.1.2.1. CIFS Server Requirements
This document assumes that you are using a Windows NT file server, version 4.0 or later
(2000/XP/2003/2003 R2/2008/2008 R2). However, you should be able to use any CIFS file server.
Usernames and passwords must be synchronized between the file server and the ThinLinc server.
Usually, this is accomplished by letting the ThinLinc servers and the CIFS file server use a common
directory server. For details, please refer to Chapter 9.
10.1.2.2. ThinLinc Server Requirements
Either of smbmount/smbumount or mount.cifs/umount.cifs must be installed. On Red Hat distributions,
they are available in the package samba-client. Refer to your distribution for how to install these
applications.
The programs smbmnt/smbumount and mount.cifs/umount.cifs must be setuid root. This is accomplished
by the following commands:
