Samba needs "...client software on the PC..."

**kevcoder** · June 13th, 2011

from Samba.org at http://www.samba.org/samba/docs/man/...diagnosis.html

What software is this referring to??

5. Run the command nmblookup -B ACLIENT `*'.
You should get the PC's IP address back. If you do not, then the client software on the PC isn't installed correctly, or isn't started, or you got the name of the PC wrong.

It's referring to the samba client (smbclient)

OK so this is some type of ftp clone... but is it required for SAMBA to work? I don't it see it mentioned in any other how-to's... not even the one on samba.org.

I'm trying to open a ubuntu share to a number of WIN7 machines.

What do you mean by required? It is the command line interface to the Samba daemon smbd. Of course you need it, but you don't have to use it if you don't want to.

I'm trying to open a ubuntu share to a number of WIN7 machines.

Are you having problems doing that? If so, what errors do you get? Did you pass the first two steps?

What did you get with
Code:
```
testparm -s
```
Can you ping all hosts from all hosts?

kevcoder00 is the Ubuntu box

I think should comment out the "netbios name = " section.
Comment out the lanman auth entries
See if the nmbd daemon is running
Code:
```
pgrep -l mbd
```

See if that works. It might not, but it is a start.

What are the IP addresses of all the hosts involved. On the Ubuntu host, can you post the output of

Code:

cat /etc/hosts

I really don't like using security = share you loose Samba control of the share.

**kevcoder** · June 14th, 2011

if I didn't already say this, I've been running linux for a full 4 months now although I work as a .Net developer. So I understand the concepts, but have almost no idea where anything is in linux/unbuntu...

... at work now so this is from memory...

I added a new user/group (Kevin/Kevin) to that matches my WIN7 user and password

Correcting the netbios name in smb.conf now allows me to see the samba share in Nautilus.

I'll change security to user and remove those lines form smb.conf. I assume that this means I should run

Code:

chown -R Kevin:Kevin /srv/samba/Share

and set a password for samba with

Code:

smbpasswd -a Kevin

In the output from smbclient -L kevcoder00 KLSTRFK is the WIN7 machine and METALWAVE is the workgroup name in WIN7 and smb.conf

I have no idea why NETBIOS over TCIP is disabled, or how to change it in Ubunto.
From the WIN7 machine ipconfig/all reports

Code:

NetBIOS over Tcpip ..... Enabled

Once again, I can ping both machines from each other and from themselves by name and ip. I can reach the apache server from WIN7 and navigate the php files there fine.

thanks for any and all help... I appreciate it!

I was there once.

I started with DOS in in the 1980's and moved on to SUN OS and later Solaris. My first Linux machine was Debian potato some 11 or 12 years ago.

... at work now so this is from memory...

I added a new user/group (Kevin/Kevin) to that matches my WIN7 user and password.

This is correct including the smbpasswd -a command. This adds the user to the Ubuntu and to Samba. Note: the practice is to use all lower case in Linux. The OS is case sensitive. My login is capscrew not Capscrew.

Correcting the netbios name in smb.conf now allows me to see the samba share in Nautilus.

I'll change security to user and remove those lines form smb.conf. I assume that this means I should run

Code:

chown -R Kevin:Kevin /srv/samba/Share

and set a password for samba with

Code:

smbpasswd -a Kevin

IMHO, Linux in general and Samba data in particular are best controlled by the correct use of groups. For example I created a group called smbusers for my Samba users. All users on the Ubuntu host that are also users of the Samba services are in that group.

This makes the share much more flexible. I don't care who owns the file since all users can access it via the group permissions. If I want to restrict users I can always use the parameter valid users = for that purpose.

Now guest users parameters make sense. If a file is created it will be with the user nobody, but I force group to be smbusers. As you can see the smbusers group allows all files to be available to all Samba users. I DO NOT put the user nobody in the smbusers group.

In the output from smbclient -L kevcoder00 KLSTRFK is the WIN7 machine and METALWAVE is the workgroup name in WIN7 and smb.conf

I have no idea why NETBIOS over TCIP is disabled, or how to change it in Ubunto.

Netbios names are resolved by the daemon (service) nmbd this is also converts DNS (hosts) names to netbios names. This means you really don't have to declare the netbiso name in the smb.conf file as you did. We do have to make sure it is running though. To check if nmbd is running youcan do this

Code:

ps -e|grep mbd

This shuld return somthing like this

Code:

 ps -e| grep mbd
  943 ?        00:00:00 smbd
  978 ?        00:00:00 nmbd
 1080 ?        00:00:00 smbd
 1629 ?        00:00:00 smbd

From the WIN7 machine ipconfig/all reports

Code:

NetBIOS over Tcpip ..... Enabled

Once again, I can ping both machines from each other and from themselves by name and ip. I can reach the apache server from WIN7 and navigate the php files there fine....

I think we have the connectivity working fine, so that is not an issue.

**kevcoder** · June 15th, 2011

I can do everything on that checklist but run the following from WIN7: both report that the machine is unreachable

This is a networking connectivity issue. Do you have any firewalls running that would get in the way?

The problem does appear to be a Windows problem.

I believe the "Called name not present..." error is the WORKGROUP name getting lost. This shouldn't stop you from looking at the share, but it might hinder GUI browse functions.

I can't see what you have done as far as your host name to IP mapping, so I can't really advise you directly. Are the DNS (hosts) names the same as the COMPUTER NAMES? Are you sure you can ping by hostname. Remember hostnames are not COMPUTER NAMES. Can you successfully use either smbclient or net view with IP addresses?

What is the hostname of KLSTRFK? What do you get from it using this command

Code:

hostname

What do you get when you use

Code:

smbtree -d3

You might look at the log files for errors. They are located at /var/log/samba. You can use the command tail to view the last entries. The default is the last 25 lines. You can increase this with tail -50 or so. the command looks like this in my case

tail -50 /var/log/samba/log.malibu
