Using this you can simulate a smb +filesystem. + +Currently this code only works on Linux with glibc2. Eventually I hope +to make it portable to lots of OSes but at the moment if you don't +have Linux then don't even try to use it. + +To use it you need to do this: + +export SMBW_USER=username +export SMBW_PASSWORD=username +export LD_PRELOAD=full_path_to_smbwrapper.so + +then try to access /smb/SERVER/SHARE/ and see what happens. + +For debugging you can set SMBW_DEBUG to an integer debug level. + +This is code under development. Lots of things don't work yet. Quite a +few things do though, for example I've successfully run tar, less, ls, +bash, cmp, cat, du and a bunch of other utilities on files accessed +via this library. + +If you want to help with the development of this code then join the +samba-technical mailing list. + diff --git a/source3/smbwrapper/access.c b/source3/smbwrapper/access.c new file mode 100644 index 0000000000..4e77113108 --- /dev/null +++ b/source3/smbwrapper/access.c @@ -0,0 +1,32 @@ +/* + Unix SMB/Netbios implementation. + Version 2.0 + SMB wrapper functions + Copyright (C) Andrew Tridgell 1998 + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
