snmp

http://www.bynkii.com/archives/2007/12/a_primer_to_snmp_on_mac_os_x_1.html

3 things to do for SNMP:

(1)query a value and get a reply

(2)set a value and get a return code

(3)An SNMP-enabled device can send you a notification, or "trap"

OID(object identifier)

how you identify SNMP objects in a structured, unique manner.

root of OID tree:

.1.3.6.1  (iso(1).org(3).dod(6).internet(1) )

within .1.3.6.1, there are four branches:

directory(1)

mgmt(2)

experimental(3)

private(4)

mgnt(2) is for standard objects

private(4) is for company-specific objects

MIB(management information base):

help user to understand the meaning of OID,

ex:

.iso.org.dod.internet.private.enterprises.4526.4.3.1.1.0 = STRING: "00146C689987"

is translated to

.iso.org.dod.internet.private.enterprises.netgear.wireless.wg102.sysSettings.sysMacAddress.0 = STRING: 00146C689987

snmpget:

snmpget -c public  192.123.1.1  1.3.1.2.1

snmpwalk:

找出某個節點後所有的value

snmpwalk -c public 192.168.5.18 .1.3.6.1.4.1.1714.1.1.2.1.2

@property & @synthesize

@property :

define getter  & setter method

ex:

@property(readwrite, assign)  int test;

@synthesize:

implement getter & setter method

ex:

@synthesize test;

binding

ex:

binding Slider's value to a key, then slider's value will sync with key

How to do:

In slider's inspect, set its binding 

(1)set bind to class A

(2)set A's  test member as model key path

key value coding

ex:

.h檔

@interface AppController : NSObject {

int test;

}

@end

.m檔

// set test

[self setValue:[NSNumber numberWithInt:5]

forKey:@"test"];

// get test

NSNumber *n=[self valueForKey:@"test"];

// is called when valueForKey is called

-(int)test

{

NSLog(@"test is returning %d", fido);

return fido;

}

// is called when setValue is called

-(void)setTest:(int)x

{

NSLog(@"setTest is called with %d", x);

fido=x;

}

delegate

if B is delegate of A,  when something happens to A,  B's method is called

ex:

B is  TableView's delegate 

B implement following method:

-(void)tableViewSelectionDidChange:(NSNotification*)notification 

when the selection row is table is changed ,  this method is called

NSTableView

data source:

decide the content of the table

implement two methods:

-(int)numberOfRowInTableView:(NSTableView*)tv

-(id)tableView:(NSTableView*)tv

                           objectValueForTableColumn:(NSTableColumn*)tableColumn

                           row:(int)row

NSWindow

initialFirstResponder outlet:

this outlet decides which view should be receiving keyboard events when window appears 

NSButton, NSSlider

NSButton:

oval button, square button ,  check box

methods:

-(void)setEnabled:(BOOL)yn

-(int)state

if return NSOnState(1), the check box is on

if return NSOffState(0), the check box is off

-(void)setState:(int)aState

NSSlider:

-(void)setFloatValue:(float)x

-(float)floatValue

NSTextField:

-(NSString*)stringValue

-(void)setStringValue:(NSString*)aString

NSFormatter can convert a string into another type , and vice versa

-(NSObject*) objectValue

-(void)setObjectValue:(NSObject*)obj

problem: No Permission to access this virtual machine

answer:

change owner of each file of virtual machine

ex:

sudo chown  -R ${USER}  *

redirect output

use >

> should be preceded with a number, such as 2>  , but default is 1 if no number

ex:

ls > output

equals   

ls  1> output

ex:

Sending Both Output and Error Messages to Different Files

test 1> messages.out  2> message.err 

or 

test > messages.out  2> message.err 

2 means STDERR

add & after >:

means the output is redirected to a file descriptor

ex:

ls >& 2

write STDOUT & STDERR to the same place:

ex:

ls >& outfile 

or 

ls > outfile 2>&1 

run the command in the background

put & after command:

ex:

ls &

/dev/null

/dev/null:

throwing output away,  redirect output to /dev/null

ex:

ls > /dev/null

</array>

not including other jars when creating jar

comment  zipgroupfileset refid="lib.jars"

when the resource is the same location as execution file, how to set resource:

1. if execution file is jar(in jars/) , put resource in jars/ and use "java -jar" to run program

2. if execution file is App(in dist/), put resource in dist/  and run from xcode

3. place them in the bin/packageName/  

define macro in xcode

ex:

configuration: Debug

gcc 4.0 processing-> preprocessor macros:   _DEBUG

memory management in objective-c

retain:

increase retain count

release:

decrease retain count

array:

when an object is added to the array, the object's retain count is increased

when the array is deallocated,  the object( in array) 's retain count is decreased 

dealloc:

when an object's retain count becomes 0, its dealloc method is called

autorelease:

the object is added to autorelease pool when it is sent message autorelease

when the pool is drained, it sends message release to all objects in the pool

objects created by alloc, new, copy or mutableCopy have a retain count of 1 & are not in the autorelease pool 

if the object is get from other method, it is usually in the autorelease pool. If you do not want it to be deallocated when the pool drain, you must retain it

memory control for setter:

retain , then release

ex:

-(void)setName:(NSString*)name

{

      [name retain];

      [myName release];

      myName= name;

}

NSObject

(id)init

(NSString*)description:

when NSLog print object, it will print the return value of description of the object

(BOOL)isEqual:(id)anObject

for NSString, isEqual will compare characters 

note: == compare if two objects are the same objects

NSString

start with @

ex:

NSString *test= @"hello";

NSString to C string

ex:

char *test = [ a UTF8String];

C string to NSString:

ex:

a= [NSString stringWithUTF8String:test];

NSLog

similar to printf in C

ex:

NSLog(@"hello");

token for NSLog:

%@: id

NSNumber

initWithInt

NSMutableArray & NSArray

NSArray:

objectAtIndex

NSMutableArray:

addObject:

ex:

[test addObject:dog1];

class and object

calling method:

ex:

[test run];

test is a object, run is its method

calling method with arguments:

ex:

[test run:1  secondArg:2];

1 is first argument,  2 is second argument, secondArg: is the description of second argument

create a object:

test = [NSMutableArray alloc];

create & init a object:

test = [  [NSMutableArray alloc] init];

TextField

setStringValue:

ex:

[textField setStringValue:@"hello"]

setIntValue:

type in objective-c

id:  a pointer to any type of object

BOOL::

YES: 1

NO: 0

IBOutlet:  a macro that evaluates to nothing. It is a hint for interface builder

IBAction:  the same as void,  a hint for interface builder

nil:  the same as NULL.  for pointers to objects

        In Objective-C, it is ok to send message to nil. The message is simply discarded.

interface builder and nib

the application's GUI is designed by interface builder

GUI is defined in the nib file.  

Use interface builder to open nib file & design gui

define class used in the nib

IBOutlet

instance variable points to other object is called outlet

ex:

IBOutlet  NSTextField *testField;

IBAction

the method is called by user interface objects

ex:

-(IBAction)seed:(id)sender;

create an object instance:

1. drag object from Library window to doc window

2. set its class to object's class name in the Identity Inspector

make connection:

connect two objects

ex:

a object has outlet textFiled of type TextField , then connect textFiled to  TextFiled GUI

ex:

when button b is pressed, it calls the method test in object c. Then connect b to object c's methods test

awakeFromNib:

all objects are sent the message awakeFromNib after the objects in nib file are brought to life

Hence, we can do something in awakeFromNib to init GUI

grep

find string in the file 

parameter:

-n:  show line number

ex:

grep -n  "rabbit"  test.rb

xcode debug

step over:

execute the function and move to the line after function

step into:
