Samba / smbd on Centos 6.5

I've installed Samba4 and have the smb.conf file as follows:

 [global]
         workgroup = WORKGROUP
         server string = Samba Server
         realm = REXIALO.COM
         netbios name = REXIALO.COM
         security = user
         map to guest = Bad Password
         bind interfaces only = no
         interfaces = lo venet0
         log file = /var/log/samba/samba.log
         max log size = 1000
 
 [webroot]
         path = /usr/local/apache/htdocs
         comment = Example.com webroot directory
         read only = No

I can connect from the same server with smbclient.

Localhost:

# smbclient -L localhost -U root

Domain=[WORKGROUP] OS=[Unix] Server=[Samba 4.1.11]

    Sharename       Type      Comment
    ---------       ----      -------
    webroot         Disk      RexiAlo webroot directory
    IPC$            IPC       IPC Service (RexiAlo Samba Server) Domain=[WORKGROUP] OS=[Unix] Server=[Samba 4.1.11]

    Server               Comment
    ---------            -------

    Workgroup            Master
    ---------            -------Enter root's password:

network:

# smbclient -L rexialo.com -U

Domain=[WORKGROUP] OS=[Unix] Server=[Samba 4.1.11]

    Sharename       Type      Comment

    IPC$            IPC       IPC Service (RexiAlo Samba Server) Domain=[WORKGROUP] OS=[Unix] Server=[Samba 4.1.11]

    Server               Comment
    ---------            -------

    Workgroup            Master
    ---------            -------

The problem is when I try to map to the smb webroot from Windows 7, it asks for user/pass but just times out and then prompts for credentials. The samba.log file does not show any activity other than the startup of the smbd process.

Any help would be appreciated.

Solution 1:

You should have same WORKGROUP configured in Samba and in Windows machine.

If you have "workgroup = WORKGROUP"

then you should change this also on windows machine to WORKGROUP.

Double check firewall on windows machine and other settings, run tcpdump on samba server side to verify that traffic is actually coming to your server.
