This is a prelodable shared library that provides SMB client services
for existing executables. Using this you can simulate a smb
filesystem.
*** This is code under development. Some things don't work yet ***
Currently this code has been tested on:
- Linux 2.0 with glibc2 (RH5.1)
- Linux 2.1 with glibc2
- Solaris 2.5.1 with gcc
- Solaris 2.6 with gcc
- SunOS 4.1.3 with gcc
- IRIX 6.4 with cc
- OSF1 with gcc
It probably won't run on other systems without some porting. If you
have a different system then see the file PORTING.
To use it you need to do this:
1) build smbwrapper.so using the command "make smbwrapper"
3) run smbsh
You will be asked for a username and password. After that you will be
returned to a shell prompt. It is actually a subshell running with
smbwrapper enabled. You can confirm this by checking if the SMBW_USER
environment variable is defined.
Now try to access /smb/SERVER for some SMB server name and see what
happens. If you set SMBW_WORKGROUP to your workgroup or have workgroup
set in yoru smb.conf then listing /smb/ should list all SMB servers in
your workgroup.
ENVIRONMENT VARIABLES
---------------------
SMBW_USER
This is usually set by smbsh but you can set it manually. It
specifies the username you will connect to servers with.
SMBW_PASSWORD
This is usually set by smbsh but you can set it manually. It
specifies the password used to connect to smb servers.
SMBW_DEBUG
This is an integer that controls the internal debug level of smbw. It
defaults to 0, which means no debug info.
SMBW_LOGFILE
The place where smbw debug logs are put. If this is not set then
stderr is used.
SMBW_PREFIX
The root of the SMB filesystem. This defaults to /smb/ but you can
set it to any name you like.
SMBW_WORKGROUP
This is the workgroup used for browsing (ie. listing machines in the
/smb/ directory). It defaults to the one set in smb.conf.
ATTRIBUTE MAPPING
-----------------
smbwrapper does an inverse attribute maping to what Samba does. This
means that the archive bit appears as the user execute bit, the system
bit appears as the group execute bit and the hidden bit appears as the
other execute bit. You can control these with chmod. The mapping can
be enabled an disabled using the normal smb.conf controls (ie. "map
archive", "map system" and "map hidden").
Read-only files appear as non-writeable by everyone. Writeable files
appear as writeable by the current user.
WHAT WORKS
----------
Things that I have tried and do seem to work include:
emacs, tar, ls, cmp, cp, rsync, du, cat, rm, mv, less, more, wc, head,
tail, bash, tcsh, mkdir, rmdir, vim, xedit, diff
things that I know don't work:
anything executing from the share
anything that uses mmap
redirection within shells to smbsh files
