[Samba] Unable to connect to Samba server, but it shows on the network

[renito73 Михаил]

 Hello friends

I am trying to setup Samba on my Fedora 19 installation, but it does not work... although "smbclient -L myserver" shows my shares, I can't access any of them from other computers and even from the same server, it returns an error that could not connect to to the server...

My very simple configuration is this (my computer has fixed IP)

[global]
        workgroup = MYGROUPNAME
        server string = Samba Server Version %v

        # log files split per-machine:                                                                                                                                  
        log file = /var/log/samba/log.%m
        # maximum size of 50KB per log file, then rotate:                                                                                                               
        max log size = 50

        security = user
        passdb backend = tdbsam

        load printers = yes
        cups options = raw

[tmp]
comment = temporal files
path = /tmp
public = yes
writable = yes
printable = no

[mp3]
comment = my data files
path = /mydatafiles
public = yes
writable = no
printable = no


I start the service by running

# smbd -D
# nmbd -D

then the logs show:

log.nmbd:

When I try:

# smbclient -L myserver (the name of my computer)

From windows computers, it shows on the network, from Linux (dolphin browser) it does not show but calling 'smbclient -L myserver' it shows the shared directories... how can I allow other computers to connect? and how can I allow my local computer see its own shares?

Thanks for your help
