[How to] Setup Samba in Linux

Let see my setup environment:

Server:
- Arch Linux  4.2.5-1-ARCH
- samba Version 4.3.3

Client:
Same as server

Network Setup:
Internet - Server(192.168.1) - Router(192.168.2) - Clients

= = =
Setup procedure:
1. Installation: (For both server and client)

#pacman -Syu samba

2. Setup config

I have made a config file to share the server /tmp folder and allow only me and home subnet only.

= = =
[global]
   workgroup = WORKGROUP
   server string = Samba Server
   hosts allow = 192.168.1. 127.
   printcap name = /etc/printcap
   load printers = yes
   log file = /var/log/samba/%m.log
   max log size = 50
   security = user
   dns proxy = no
   invalid users = nobody root
   map to guest = Bad User
   max connections = 10
[homes]
   comment = Home Directories
   browseable = no
   writable = yes
[tmp]
   comment = Temporary file space
   path = /tmp
   valid users = your_user
   public = no
   writable = yes
= = =

Configure your user to samba, and enter the user password.
#pdbedit -a -u your_user

3. Run

In server:
#systemctl enable smbd.service

If you also need netbios support:
#systemctl enable nmbd.service 

Server side should be more or less ready and change to Client

Client:

Just test the samba connection to the server

user@localhost:~$ smbclient -L 192.168.1.1 -U your_user
smbclient: Can't load /etc/samba/smb.conf - run testparm to debug it
Enter your_user's password:
Domain=[WORKGROUP] OS=[Windows 6.1] Server=[Samba 4.3.3]

        Sharename       Type      Comment
        ---------       ----      -------
        tmp             Disk      Temporary file space
        IPC$            IPC       IPC Service (Samba Server)
        your_user       Disk      Home Directories
Domain=[WORKGROUP] OS=[Windows 6.1] Server=[Samba 4.3.3]

        Server               Comment
        ---------            -------
        LOCALHOST            Samba Server

        Workgroup            Master
        ---------            -------
        WORKGROUP            LOCALHOST


If you see similar output, the connection should be ready and you can mount remote samba drive

#mount -t cifs //LOCALHOST/tmp /mnt -o user=your_user,workgroup=WORKGROUP,ip=192.168.1.1
password:


Nice and Done!!

[How To] turn arch linux box to a wireless Access Point in the simplest way

Access point setting may be a little difficult for general linux user, I would like to introduce a one step way to use your linux box with a USB wifi dongle to change it to a wireless AP

1. Identify your USB wifi dongle support AP mode or not.
In order to turn your USB wifi to Access Point, your USB dongle must support AP Mode. you may check if it is supported by following:

$iw list
Wiphy phy1
    max # scan SSIDs: 4
    max scan IEs length: 2285 bytes
    Retry short limit: 7
    Retry long limit: 4
    Coverage class: 0 (up to 0m)
    Device supports RSN-IBSS.
    Supported Ciphers:
        * WEP40 (00-0f-ac:1)
        * WEP104 (00-0f-ac:5)
        * TKIP (00-0f-ac:2)
        * CCMP (00-0f-ac:4)
        * 00-0f-ac:10
        * GCMP (00-0f-ac:8)
        * 00-0f-ac:9
        * CMAC (00-0f-ac:6)
        * 00-0f-ac:13
        * 00-0f-ac:11
        * 00-0f-ac:12
    Available Antennas: TX 0 RX 0
    Supported interface modes:
         * IBSS
         * managed
         * AP
         * AP/VLAN
         * monitor
         * mesh point                  ...

 If you plug in your usb dongle and the Supported Interface modes do not have the "AP" mode, you need another usb module. Most likely for my personsal recommendation Atheros Chipset is a good choice.

2. Introduce to you a create_ap script. You may find it in the following link:
https://bbs.archlinux.org/viewtopic.php?pid=1269258

or from AUR
https://aur.archlinux.org/packages/create_ap/

Just install it and with the dependencies.

Just simply run a command

#create_ap wlan0 eth0 MyAccessPoint MyPassPhrase

And it is Done!! How come it is so easy.

There is a word for Chinese People "前人種樹後人蔭" "People plant trees, childen cools under tree"

Thanks for open source

New Computer - migrate arch linux from AMD to intel

For years my computer is used, it was found dead after 7 years of working of my AMD Computer. After recover from sadness, I bought new parts to fix it. As the original one was using DDR2 which is quite outdated, I bought a new (not means fast) CPU and mainboard.

Let see the migration spec:
Original Config:
AMD Athlon II X2 240e
J&W Nvidia Geforce 8200 Mainboard
2GB x4 DDR2 RAM
GPU: nvidia onboard

New Config:
Intel Pentium G3258
Asrock B85 Mainboard
8GB x1 DDR3 RAM
GPU: intel onboard

Software:
Arch Linux 3.18.6-ARCH 64bit

After connect everything, computer bootup as usual. It boot up successfully to console user login.

The following is not work:
1. X
2. network

For the network part as the interface index was changed, just amend the configuration on netctl, the dnsmasq (dhcp server and dns provider) and dhcp client and everything works great. Just a reminder that the service of original setting was still running, and these services should be stopped.

For X windows, as I original was using the open-source driver xf86, what I need to do is uninstall nouveau, remove all the configurations and install package "xf86-video-intel" from pacman and it works!!
