Samba problem

itd_pac · 04-23-2006, 06:29 AM

hi gud day to all. I just configured my samba, but i have encountered problem in accessing on my windows xp machine. I was able to see the Samba server on the xp machine but when i click on it i encountered an error \\Localhost is not accessible. you might not have permission tyo use this network resource.
I did not set any password on my xp machine and also the firewall was turn off. below is my smb.conf details. Pls help

What distro do you use? Fedora, and I'd guess anything else that employs SELinux, can be problematic because of SELinux. I had to turn off SELinux security for smbd.

rolsch · 04-23-2006, 07:30 AM

First take a look at the following line

Code:

hosts allow = 192.168.1. 192.168.2. 127.

You have to make sure that the IP address of your XP box is within one of those subnets.

Next there is only one share defined (homes), which is used for specific users logging on. But you defined share level security. Try to change to user level security:

Code:

security = USER

Setup a share like this.

Code:

[test]
   comment = test share
   path = /your/path
   browseable = yes
   read only = yes
   writable = no
   public = yes
   guest ok = yes
   map to guest = bad user

Define a valid guest account.

Code:

guest account = nobody

Make sure the directory of your share is readable and executable by your guest account (in this case "nobody").

Restart your samba server.

Next, open a command prompt window on your XP box and type the following:

Code:

nbtstat -RR
nbtstat -r

You should see a list of discovered netbios servers including your samba server. If so, netbios is working. If not, there is probably something wrong with the firewall on your linux box. You should allow IP broadcasts and ports 137, 138, 139 for TCP and UDP.

Now try to connect directly to your share:

Code:

net use * \\linux-server\test

There is no need to specify a specific user account, because you enabled the guest account.

manishsingh4u · 04-23-2006, 07:54 AM

If you really want your shared folders to be available to specific users, switch to root and type the command -

Code:

smbpasswd -a anyusername

give a password.
And you will get a message like

Code:

Added user anyusername

Now, in your /etc/samba/smb.conf file

Code:

[test]
   comment = test share
   path = /your/path
   writable = no
   public = no
   valid users = anyusername

Like what rolsch have written,
you must check this line, try commenting it for a while if not sure.

Code:

hosts allow = 192.168.1. 192.168.2. 127.

hi thanks for the reply. I have refreshed by netbios on my XP machine using this command nbtstat -RR and nbtstat -r, and also allowed the UDP as well the TCP for 139,137, and 138 on my IPtables. Also the ip of of both my linux and my XP machine were both on 192.168.1 addresses. Iver tried turning off the firewall for both machine but still unable to access. Btw now i can see the samba server but when i click on it it will ask for my password but when i type the correct passwrd it does not accept. my passwrd is only 123456 for testing. and when i access it again the error reoccur that it unable to access \\localhost is not accessible/ You might not have access on the network resources. Im using Redhat 9.0. below is my testpram result. thanks

RH9 assigned localhost to be the computers hostname however it isn't a valid network name. localhost is the local network loopback device i.e. 127.0.0.1 on all computers so your actually trying to connect to the XP PC instead of the linux PC. samba by default uses the computers hostname but you can change the network name in the smb.conf file global section as shown below. Change linux to the name of your choosing.

netbios name = linux

Be sure to restart samba for the changes to take effect.

thanks for the reply. i have configured samba the same way with your instructions and samba now working.. thanks to all who have shared their knowledge
