But this article is to describe how to allow a Windows computer access
READ/WRITE to a Linux computer in a very quick, easy, simple way.

For Arch Linux, here is what I did to achieve above purpose.

1. Install samba package
sudo pacman -S samba
sudo pacman -S smbclient

2. Edit config file

By default, we have a sample config which you can copy and edit itself.
cp /etc/samba/smb.conf.default /etc/samba/smb.conf

And then, vim /etc/samba/smb.config

In [global] section, you may want to edit two line:

workgroup
server string

This is optinal so identify your computer easily on network

And then, go to [public] to edit it to your own need.:w
This section is to define public folder which everybody can access to it.

3. Adding user.

At this time, every thing is ready but you need to add an user with the same
name of one of the account on your system. Later, on Windows, once Windows user
go to Network > Linux Computer, they will be asked for an username/password.
They will need this password.

Because I’m using Linux under account lambasino so I run command:

sudo pbedit -a -u lambasino

And then I entered a password for this samba account. Remember, this is a
password for SAMBA, not password for current account under linux system so you
can enter anything you like. This username/password pair is to other user on other computer connect to your machine via it. This way your real password will be not exposed to the world. You give them samba username/pass instead.

4. Start samba server
sudo rc.d start samba

That’s all.

On Windows, go to, enter the username/password which you created as above. Ok,
it’s time to copy something fun over your LAN network ;P

1. Install apache, php, php-fpm package
sudo pacman -S apache php php-fpm

2. create alias to php binary

ln -s /usr/bin/php-cgi /srv/http/php5.fcgi
3. Edit config file

Make sure you don’t load apache php module. Remove all the lines which you added when installing php as an apache module.

Open the file /etc/httpd/conf/httpd.conf, make sire these link were there. If not, add them

# PHP – FPM
Include conf/extra/httpd-fpm.conf

Then we create conf/extra/httpd-fpm.conf as following:

LoadModule fastcgi_module modules/mod_fastcgi.so

Alias /php5.fcgi /srv/http/php5.fcgi
# Assign the ‘fake’ fcgi to call to an ‘external’ FastCGI Server
FastCGIExternalServer /srv/http/php5.fcgi -flush -host 127.0.0.1:9000 -pass-header Authorization

# Create the handler mappings to associate PHP files with a call to ‘/php5.fcgi’
AddType application/x-httpd-fastphp5 .php
Action application/x-httpd-fastphp5 /php5.fcgi

Config /etc/php/php-fpm.conf for listen setting. When you installed php-fpm, this file is created for you. You just need to open it and carefully go over settings there to confirm if nothing wrong for your machine setting

4. Running

run apache first, then run php-fpm

sudo rc.d start httpd
sudo rc.d start php-fpm
Troubleshoot: If you see this error when connectiong to MySQL: #2002 – The server is not responding (or the local MySQL server’s socket is not
correctly configured)

Edit setting for mysql socket in /etc/php.ini

mysqli.default_socket = /var/run/mysqld/mysqld.sock
mysql.default_socket = /var/run/mysqld/mysqld.sock

Normally it is /var/run/mysqld/mysqld.socket
You can double check via reading file /etc/mysql/my.cnf:

# The MySQL server
[mysqld]
port            = 3306
socket          = /var/run/mysqld/mysqld.sock
datadir         = /var/lib/mysql
skip-external-locking
key_buffer_size = 16M
max_allowed_packet = 1M
table_open_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M

If you used bash. simply edit ~/.bashrc and put these lines:

export CLICOLOR=1

export LSCOLORS=GxFxCxDxBxegedabagaced

If you used zsh, simply edit ~/.zshrc and put above lines.

If you added GCDAsyncSocket classes, and see these errors when compiling:

Then make sure you added these libraries:

• Security.Framework
• CFNetwork.framework

unrecognized selector sent to instance

If you google this error, it leads you to very complicated topics for a beginner:

http://stackoverflow.com/questions/861626/how-to-resolve-unrecognized-selector-sent-to-instance

Actually, my problem is much simpler. I forgot to define ancestor method for a property. I added a outlet in .h file, but in .m file I forgot to define getter and setter method, or in otherwords, I didn’t put indicator @synthesize .

I noted here so if you see something with above message, make sure you didn’t forgot any @synthesize or you need to define 2 accessor methods yourself:

• - (NSString *)userName
• - (void)setUserName:(NSString *)newUserName

Error: Cannot write to /usr/local/Cellar

I do

ls -la /usr

and got this

For some reasons, /usr/local belongs to admin group insteads of wheel. with sudo, we need to have it in group “wheel”. I recall that this happened after I manually change the username. I had an account on Mac Mini with username “vinhnguyen”. I then decided to change it, so I manually enable root account and change the name of home folder. After I do that, /usr/local became to belong to admin group.

Futher, if I continue to check /usr/local, I got:

loho:~ kureikain$ ls -la /usr/local/

drwxrwxr-x  10 root        wheel  340 May  4 14:02 .

You may get following error:

Error: Permission denied - /usr/local/include

So, I can say permission got messing up after I manually change account name from vinhnguyen to kureikain. So we need to manually correct permission again.

sudo chgrp wheel /usr/local/

sudo chown -R $USER /usr/local/

After you do that, everything should work fine.

loho:~ kureikain$ brew install wget

Let use utility pbcopy

pbcopy < /path/to/file/need/to/copy/its/content

After that your clipboard will be fill in with file’s content.

• Go to Terminal > Preference > Settings > Keyboards
• Find the home/end key. By default, it shows action columns as: “scroll to home/end of buffer”. You need to edit and change that action to send “send string to shell”
  
• Do the same for other keys. You will need to put a string which will be send to shell and shell take care the rest for you. Here is the list of strings:
  

  Home	\033[1~
  End	\033[4~
  Page Up	\033[5~
  Page Down	\033[6~

Hope this will help s.o who is starting to use Mac like me .
