Configuring the system
2.5 Description of the actions
Without the -sec option, the value of variable "DefaultCIFSSecurity" is used in basesys.ini
(Page 25). If this is also not defined, then the default setting is NTLMv1 or NTLMv2.
NOTICE
Authentication
It is recommended that NTLMv1 is no longer used, as the security associated with this
technique is no longer guaranteed.
Notation of the remote file system
For SMB and NFS/TCU, the file system is entered using different notations:
SMB: //[USERNAME[/DOMAIN][%PASSWORD]@]SERVER/SHARE
The fixed share is: //SERVER/SHARE
The server name can of course also be a numeric IP address. SHARE is the name of the
release on the server. Note that the character '$', which often occurs in this type of name, must
be preceded by a backslash ('\') in the command line. Otherwise, the system tries to expand
a variable.
A user name can also be entered in front of the server name, separated with a '@' character.
If necessary, the user name can also be extended by adding '/' followed by the Windows domain
to which it belongs. The password belonging to this user is normally queried interactively, so
that it is not visible on the screen.
For some applications, however, it may be necessary to write the password in the command
line. (For example, programs started from WinSCP cannot read from the keyboard.) In this
case, you can append an additional '%' character, followed by the password. If this contains
any special characters that are interpreted by the shell (<, >, &, ;, ", ', $, (, ), |), you should
shield these by preceding them with a backslash. Commas in SMB passwords cannot be
interpreted.
NFS: SERVER:/PATH
In NFS, entering the user is not required, which just leaves the two components SERVER and
PATH. As before, SERVER is the name of the file server. In contrast to SMB, PATH is a path
name that exists on the server, and not an arbitrarily assigned name.
The command "sc show drives SERVER" shows the file systems offered by a particular server
in the correct notation. For SMB, if required, the user name, etc. still need to be added.
After the entry of the remote file system, you can also specify the required directory
('MOUNTPOINT') in which the remote files will become visible locally. This should be an empty
directory to which you have write access. If MOUNTPOINT is omitted, 'sc' itself generates a
suitable directory. The name is /tmp/drvNN (numbered consecutively), and is displayed when
the connection is successful.
The "-ro" option connects the remote file system in read-only mode, this means that you can
only read and do not have write access. This can be useful if you want to exclude changes
that originate from the control, or if the server only allows read-only connections.
