Yes, that's it.

Using smbfs, both files have the same size and contents even though
they're really different:

$ ll ipt_dscp* ipt_DSCP*
-r--r----- 1 me me 2753 Jan 29 2004 ipt_dscp.c
-r--r----- 1 me me 2753 Jan 29 2004 ipt_DSCP.c
$ ll ipt_dscp.c ipt_DSCP.c
-r--r----- 1 me me 2753 Jan 29 2004 ipt_dscp.c
-r--r----- 1 me me 2753 Jan 29 2004 ipt_DSCP.c

With cifs, a directory search shows different sizes but opening
them by name gives identical contents:

$ ll ipt_dscp* ipt_DSCP*
-r-------- 1 me me 1581 Jan 28 2004 ipt_dscp.c
-r-------- 1 me me 2753 Jan 29 2004 ipt_DSCP.c
$ ll ipt_dscp.c ipt_DSCP.c
-r-------- 1 me me 1581 Jan 28 2004 ipt_dscp.c
-r-------- 1 me me 1581 Jan 28 2004 ipt_DSCP.c
$ diff ipt_dscp.c ipt_DSCP.c
$

So where is the bug? On the server?
