To enable the Unix CIFS Extensions in the Samba server, add the line: + unix extensions = yes +to your smb.conf file on the server. Note that the following smb.conf settings are +also useful (on the Samba server) when the majority of clients are Unix +or Linux: + case sensitive = yes + delete readonly = yes +Some administrators also change the "map archive" and the "create mask" parameters +from their default values. Creating special devices (mknod) remotely may require +specifying a mkdev function to Samba. For more information on these see the manual +pages ("man smb.conf") on the Samba server system. Note that the cifs vfs, unlike the +smbfs vfs, does not read the smb.conf on the client system (the few optional settings +are passed in on mount via -o parameters instead). Note that Samba 2.2.7 or later +includes a fix that allows the CIFS VFS to delete open files (required for strict +POSIX compliance). Windows Servers already supported this feature. + +Use instructions: +================ +Once the CIFS VFS support is built into the kernel or installed as a module (cifs.o), +you can use mount syntax like the following to access Samba or Windows servers: + mount -t cifs //9.53.216.11/e$ /mnt -o user=myname,pass=mypassword +after -o the following cifs vfs specific options are supported: + user= + pass= + domain= +TCP names (in addition to ip addresses) will be available when the mount helper +(mount.cifs) is complete + +Restrictions +============ +Servers must support the NTLM SMB dialect (which is the most recent, supported by Samba +and Windows NT, 2000 and XP and many other SMB/CIFS servers) and servers must support +either "pure-TCP" (port 445 TCP/IP CIFS connections) or RFC 1001/1002 support for +"Netbios-Over-TCP/IP."

There are plenty of opportunities +for visible, important contributions to this module. Here +is a partial list of the known problems and missing features: + +a) Support for SecurityDescriptors for chmod/chgrp/chown so +these can be supported for Windows servers + +b) Better pam/winbind integration + +c) multi-user mounts - multiplexed sessionsetups over single vc +(ie tcp session) - prettying up needed + +d) Kerberos/SPNEGO session setup support - (started) + +e) NTLMv2 authentication (mostly implemented) + +f) MD5-HMAC signing SMB PDUs when SPNEGO style SessionSetup +used (Kerberos or NTLMSSP).

This is important when enabling + extended security and mounting to Windows 2003 Servers + +f) Directory entry caching relies on a 1 second timer, rather than +using FindNotify or equivalent. - (started) + +g) There may be a few additional changes that could be done to take advantage +of recent 2.5 kernel improvements in byte-range locking + +h) quota support + +i) support for the Linux 2.5 kernel new feature get_xattr and set_xattr +which will allow us to expose dos attributes as well as real +ACLs + +j) finish off the mount helper, mount.cifs - (started) + +k) finish writepages support (multi-page write behind for improved +performance) and syncpage + +l) hook lower into the sockets api (as NFS/SunRPC does) to avoid the +extra copy in/out of the socket buffers in some cases. + +m) finish support for IPv6 + +o) Better optimize open (and pathbased setfilesize) to reduce the +oplock breaks coming from windows srv. Piggyback identical file +opens on top of each other by incrementing reference count rather +than resending (helps reduce server resource utilization and avoid +spurious oplock breaks). + +p) Improve performance of readpages by sending more than one read +at a time when 8 pages or more are requested. + + +KNOWN BUGS (updated July 4th, 2003) +==================================== +1) existing symbolic links (Windows reparse points) are recognized but +can not be created remotely. They are implemented for Samba and those that +support the CIFS Unix extensions but Samba has a bug currently handling +symlink text beginning with slash +2) delete of file with read-only attribute set will fail (may be ok) +3) mount helper syntax not quite matching man page +4) follow_link and readdir code does not follow dfs junctions +but recognizes them +5) create of new files to FAT partitions on Windows servers can +succeed but still return access denied (appears to be Windows +not client problem). NTFS partitions do not have this problem. + +Misc testing to do +================= +1) check out max path names and max path name components against various server +types. + +2) Run dbench.
