snmp

2008-11-26T05:23:00.000-08:00

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

2008-09-13T03:02:00.000-07:00

@property :

define getter & setter method

ex:

@property(readwrite, assign) int test;

@synthesize:

ex:

@synthesize test;

binding

2008-09-13T02:35:00.000-07:00

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

2008-09-13T02:21:00.000-07:00

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

2008-09-13T02:06:00.000-07:00

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

2008-09-13T02:01:00.000-07:00

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

2008-09-13T00:44:00.000-07:00

initialFirstResponder outlet:

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

NSButton, NSSlider

2008-09-13T00:15:00.000-07:00

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

redirect output

2008-07-25T00:56:00.000-07:00

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

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

ls > outfile 2>&1

run the command in the background

2008-07-25T00:47:00.000-07:00

put & after command:

ex:

memory management in objective-c

2008-06-24T07:44:00.000-07:00

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;

}

2008-06-15T08:25:00.000-07:00

(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

2008-06-15T08:21:00.000-07:00

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

2008-06-15T08:19:00.000-07:00

type in objective-c

2008-06-15T07:56:00.000-07:00

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

2008-06-15T07:39:00.000-07:00

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

2008-06-11T09:18:00.001-07:00

做完改變後，

若要在local端儲存改變，

按file，然後按住option，

然後選save a copy as ，

然後檔名選local端file的檔名，

如此就會覆蓋local端原本的檔案。

import:

test: project name on cvs server

andy: Vendor-tag

ver1: Version-tag

checkout:

get specific version:

cvs co -r v1_2 projectName

get specific date:

cvs co -D "12/02/2008 13:00" projectName

get specific branch

cvs co -r branch_name projectName

show status:

ex:

cvs st test.c

commit:

cvs commit test.c

remove

1. rm test.c

2. cvs rmove teset.c

3. cvs commit test.c

when check out project next time, test.c is not checked out

but test.c is still on cvs server

Hence, we can roll back the time test.c exists

svn

svn on windows: tortoiseSVN

一般分三種directories

trunk: 最新的程式

branch: 程式某個版本的branch，不會影響到最新的程式

tag: 每個release的程式，會有個tag對應，如此可以取回任何一版release的程式

將程式抓下來:

ex: svn checkout http://svn.techno-weenie.net/projects/plugins/acts_as_authenticated/
