FreeBSD – Montarea unui director partajat in retea

In multe cazuri avem nevoie sa accesam des un director partajat pe un alt calculator.
O solutie simpla de a accesa acest director este sa il montam local pentru a nu mai fi nevoie sa facem browsing in retea pentru a ajunge la calculatorul pe care e partajat si respectiv la director.
Pentru a face acest lucru vom folosi mount_smbfs

Mai jos este prezentat pagina de manual pentru aceasta comanda.

MOUNT_SMBFS(8) FreeBSD System Manager’s Manual MOUNT_SMBFS(8)

NAME
mount_smbfs — mount a shared resource from an SMB file server

SYNOPSIS
mount_smbfs [-E cs1:cs2] [-I host] [-L locale] [-M crights:srights] [-N]
[-O cowner:cgroup/sowner:sgroup] [-R retrycount] [-T timeout]
[-W workgroup] [-c case] [-d mode] [-f mode] [-g gid]
[-n opt] [-u uid] //user@server[:port1[:port2]]/share node

DESCRIPTION
The mount_smbfs command mounts a share from a remote server using
SMB/CIFS protocol.

The options are as follows:

-E cs1:cs2
Specifies local (cs1) and server’s (cs2) character sets.

-I host
Do not use NetBIOS name resolver and connect directly to host,
which can be either a valid DNS name or an IP address.

-L locale
Use locale for lower/upper case conversion routines. Set the
locale for case conversion. By default, mount_smbfs tries to use
an environment variable LC_* to determine it.

-M crights:srights
Assign access rights to the newly created connection.

-N Do not ask for a password. At run time, mount_smbfs reads the
~/.nsmbrc file for additional configuration parameters and a
password. If no password is found, mount_smbfs prompts for it.

-O cowner:cgroup/sowner:sgroup
Assign owner/group attributes to the newly created connection.

-R retrycount
How many retries should be done before the SMB requester decides
to drop the connection.

-T timeout
Timeout in seconds for each request.

-W workgroup
This option specifies the workgroup to be used in the authentica-
tion request.

-c case
Set a case option which affects name representation. case can be
one of the following:

Value Meaning

l All existing file names are converted to lower case.
Newly created file gets a lower case.

u All existing file names are converted to upper case.
Newly created file gets an upper case.

-f mode, -d mode
Specify permissions that should be assigned to files and directo-
ries. The values must be specified as octal numbers. Default
value for the file mode is taken from mount point, default value
for the directory mode adds execute permission where the file
mode gives read permission.

Note that these permissions can differ from the rights granted by
SMB server.

-u uid, -g gid
User ID and group ID assigned to files. The default are owner
and group IDs from the directory where the volume is mounted.

//user@server[:port1[:port2]]/share
The mount_smbfs command will use server as the NetBIOS name of
remote computer, user as the remote user name and share as the
resource name on a remote server. Optional port1 and port2 argu-
ments can be used to override default values of port numbers used
by communication protocols. For SMB over NetBIOS default value
for port1 are 139, and port2 are 137.

node Path to mount point.

FILES
~/.nsmbrc Keeps static parameters for connections and other information.
See /usr/share/examples/smbfs/dot.nsmbrc for details.

EXAMPLES
The following example illustrates how to connect to SMB server SAMBA as
user GUEST, and mount shares PUBLIC and TMP:

mount_smbfs -I samba.mydomain.com //guest@samba/public /smb/public
mount_smbfs -I 192.168.20.3 -E koi8-r:cp866 //guest@samba/tmp /smb/tmp

It is possible to use fstab(5) for smbfs mounts:

//guest@samba/public /smb/public smbfs rw,noauto 0 0

BUGS
Please report bugs to the author.

FreeBSD 6.0 March 10, 2000 FreeBSD 6.0

Pentru a putea monta directoare partajate in retea trebuie sa instalam samba3 din porturi.

cd /usr/ports/net/samba3/
make
make install

Fisierul de configurare pentru Samba este /usr/local/etc/smb.conf.

Presupunem ca vrem sa montam directorul Work de pe sistemul care are ip-ul 192.168.100.50 si numele NetBIOS Fileserver.
Consideram ca userul bogdan are acces sa acceseze directoarele partajate de pe acest sistem.

In primul rand ne asiguram ca putem vedea lista de directoare partajate de pe sistemul respectiv.

smbclient -U bogdan -L 192.168.100.50

Suntem intrebati de parola pentru userul bogdan. Dupa introducerea corecta a acesteia vom obtine lista de directoare partajata:

Domain=[FILESERVER] OS=[Unix] Server=[Samba 3.0.23b]

Sharename Type Comment
——— —- ——-
share Disk Work
IPC$ IPC IPC Service (Samba 3.0.23b)
Domain=[FILESERVER] OS=[Unix] Server=[Samba 3.0.23b]

Server Comment
——— ——-

Workgroup Master
——— ——-
LAN FILESERVER

Se observa ca exista partajat directorul Work.

In continuare vom monta directorul Work de pe sistemul Fileserver in directorul Work din /home/bogdan de pe sistemul pe care lucram.

mkdir /home/bogdan/Work
mount_smbfs -I 192.168.100.50 //bogdan@fileserver/Work /home/bogdan/Work/

Si la acest pas suntem nevoiti sa introducem parola pentru userul bogdan.

Daca dorim sa montam automat la pornirea sistemului acest director trebuie sa editam /etc/fstab si sa introducem:

//bogdan@fileserver/Work /home/bogdan/Work smbfs ro 0 0

Sistemul are nevoie sa stie parola pentru userul bogdan si adresa IP a sistemului care are numele NetBIOS Fileserver.
Aceste informatii le vom scrie in fisierul /etc/nsmb.conf:

[default]
workgroup=LAN
[FILESERVER]
addr=192.168.100.50
[FILESERVER:BOGDAN]
password=parola_pentru_userul_bogdan

Atentie la faptul ca se folosesc MAJUSCULE!
