added SMBW_PREFIX environment variable (allowing you to specify root
of smb filesystem) fixed "cd /smb" bug updated README with full list of environment variables. (This used to be commit 71acf338d721b106af8d80e7b3a6f318ab75da8b)

|
||||
set in yoru smb.conf then listing /smb/ should list all SMB servers in
|
||||
your workgroup.
|
||||
|
||||
For debugging you can set SMBW_DEBUG to an integer debug level.
|
||||
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.
|
||||
|
||||
This is code under development. Lots of things don't work yet.
