timer.cancel();

... kurnik..

treba to aj do tej stop v sharemeImpl. Mne to ale nejak nedava logiku, preco potom to ide aj do stop v isalivesender... bn

thx4tip

timer.cancel mam ja a aj tak to zmrzne a neukonci korektne

Ja som mal rovnaký problém, no už nemám 
Skús si pozrieť, či máš v HostListImpl.GarbageCollector.stop() riešené this.notify pomocou synchronized:

synchronized(this) {
            this.notify();
         }

ano mam to tak. Moze byt ze mam stare api? este lab1 islo norm. 2-ka uz robi ten ,,problem''

neviete čo s tým?

Discovered: January 13, 2005
Updated: February 13, 2007 12:31:53 PM
Type: Trojan Horse
Systems Affected: Windows 2000, Windows 95, Windows 98, Windows Me, Windows NT, Windows Server 2003, Windows XP


The following instructions pertain to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines.

   1. Disable System Restore (Windows Me/XP).
   2. Update the virus definitions.
   3. Restart the computer in Safe mode or VGA mode.
   4. Run a full system scan and delete all the files detected as Backdoor.Abebot.
   5. Reverse the changes made to the registry.

For details on each of these steps, read the following instructions.

1. To disable System Restore (Windows Me/XP)
If you are running Windows Me or Windows XP, we recommend that you temporarily turn off System Restore. Windows Me/XP uses this feature, which is enabled by default, to restore the files on your computer in case they become damaged. If a virus, worm, or Trojan infects a computer, System Restore may back up the virus, worm, or Trojan on the computer.

Windows prevents outside programs, including antivirus programs, from modifying System Restore. Therefore, antivirus programs or tools cannot remove threats in the System Restore folder. As a result, System Restore has the potential of restoring an infected file on your computer, even after you have cleaned the infected files from all the other locations.

Also, a virus scan may detect a threat in the System Restore folder even though you have removed the threat.

For instructions on how to turn off System Restore, read your Windows documentation, or one of the following articles:

    * "How to disable or enable Windows Me System Restore"
    * "How to turn off or turn on Windows XP System Restore"


Note: When you are completely finished with the removal procedure and are satisfied that the threat has been removed, re-enable System Restore by following the instructions in the aforementioned documents.

For additional information, and an alternative to disabling Windows Me System Restore, see the Microsoft Knowledge Base article, "Antivirus Tools Cannot Clean Infected Files in the _Restore Folder," Article ID: Q263455.

2. To update the virus definitions
Symantec Security Response fully tests all the virus definitions for quality assurance before they are posted to our servers. There are two ways to obtain the most recent virus definitions:

    * Running LiveUpdate, which is the easiest way to obtain virus definitions: These virus definitions are posted to the LiveUpdate servers once each week (usually on Wednesdays), unless there is a major virus outbreak. To determine whether definitions for this threat are available by LiveUpdate, refer to the Virus Definitions (LiveUpdate).
    * Downloading the definitions using the Intelligent Updater: The Intelligent Updater virus definitions are posted daily. You should download the definitions from the Symantec Security Response Web site and manually install them. To determine whether definitions for this threat are available by the Intelligent Updater, refer to the Virus Definitions (Intelligent Updater).

      The Intelligent Updater virus definitions are available: Read "How to update virus definition files using the Intelligent Updater" for detailed instructions.

      Note: If you see an error, such as LU1418, when you try to run LiveUpdate and you cannot get the Web site hosting the Intelligent Updater, it is likely that theTrojan has modified the Hosts file. You can either download and install LiveUpdate 2.5, which can remove Symantec entries from that file, or you can edit it yourself. See the instructions for both in the "Additional Information" section below.



3. To restart the computer in Safe mode or VGA mode
Shut down the computer and turn off the power. Wait for at least 30 seconds, and then restart the computer in Safe mode or VGA mode.

    * For Windows 95, 98, Me, 2000, or XP users, restart the computer in Safe mode. For instructions, read the document, "How to start the computer in Safe Mode."
    * For Windows NT 4 users, restart the computer in VGA mode.

4. To scan for and delete the infected files

   1. Start your Symantec antivirus program and make sure that it is configured to scan all the files.
          * For Norton AntiVirus consumer products: Read the document, "How to configure Norton AntiVirus to scan all files."
          * For Symantec AntiVirus Enterprise products: Read the document, "How to verify that a Symantec Corporate antivirus product is set to scan all files."
   2. Run a full system scan.
   3. If any files are detected as infected with Backdoor.Abebot, click Delete.



5. To reverse the changes made to the registry
Important: Symantec strongly recommends that you back up the registry before making any changes to it. Incorrect changes to the registry can result in permanent data loss or corrupted files. Modify the specified keys only. Read the document, "How to make a backup of the Windows registry," for instructions.

   1. Click Start > Run.
   2. Type regedit

      Then click OK.

   3. Navigate to the key:

      HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

   4. In the right pane, delete the value:

      "[random service name]" = "[random file name].exe -services"

   5. Navigate to the key:

      HKEY_USERS\S-1-5-21-679724519-2691042562-2408214785-1006\SOFTWARE\
      Microsoft\Windows\CurrentVersion\Run

   6. In the right pane, delete the value:

      "[random service name]" = "[random file name].exe -services -drivers"

   7. Exit the Registry Editor.

   8. Restart the computer in Normal mode. For instructions, read the section on returning to Normal mode in the document, "How to start the computer in Safe Mode."

ja mam tiez to najdenie indexu min/max cisla v ext pamati... ale tak kto je mudri tak si na stranke cybernetics najde program na najdenie min/max cisla a k tomu dorobit, zeby ulozilo aj index je uz uplna pohoda... ale aj tak to neni tazke

... a komu sa chce hladat??  (za par minut to ajtak mas hotove aj sam...)

Mam u Chovanaka.

Vytvorte aplikaciu, ktora zisti pocet parnych a neparnych cisel z N 8 bitovych cisel ulozenych v externej pameti dat od adresy 00H.

Sedi to ?
Ja uz niekolko dni sedim nad CCNA lebo v stredu final, celkovo dost nestiham, uvitam akukolvek help

na moje nesedi. ja mam index min/max cisla ext. pamati

naviac (okrem odchytavania vynimok - bo to tam musis mat aj ty bo by ti to neslo) tam mam este aj:

timer.cancel();

pricom ten mam predtym v start() takto spusteny:

timer = new Timer();
timer.scheduleAtFixedRate(aliveSender, 0, IConstants.IS_ALIVE_INTERVAL);

ale nepouziva sa toto nahodou uz v 1.6 ? no neviem inac...

si myslim ze v isalivesender.stop(); ma byt neco ako
this.cancel();

teda sa to zavolava.

Any other idea?

na ok. ta skus dodat co ty mas v stop navyse>

     isalivereciever.stop();
     hostlistimplementation.stopGarbageCollector();
     isalivesender.stop();
     Naming.unbind(uri);  //uri bol v start-e rebindovany...
     UnicastRemoteObject.unexportObject(searchengineimplementation, true);

mne vsetko stale korektne ukoncovalo... ale ked uz mas 2.x verziu tak nepotrebujes spustat nejaky druhy program na poslanie paketu na ukoncenie ale staci ti aj len tam priamo v tom spustenom tvojom napisat "bye moje_heslo" a dat ENTER (samozrejme bez uvodzoviek)

No neviem. mne po ukonceni celeho 2, sa ukoncovalo na ten bye len tak, ze vsetko sa zastavilo (thready, atd) ale nevratil sa ku bashi z javy.
(preto som tam pouzival ten exit() )
Teda ta metoda Stop ukonci vsetko, a to ze to cele sa nezastavi uz ma nesere..

Ale preco my ant run1 v pohode ukonci a DeeLov riadok pre 2.1 nie ? Aj ked som odmazal implementaciu 1.6 sprava sa to tak isto. ant2_1 v pohode ukonci build aleb pre 2.1 prikaz iba vypise ze sa aplikacia ukonci a tak zmrzne pricom zdrojak je uplne identicky. V com sa lisia tie dva prikazy ked rovnaky zdrojak rozne reaguje ?

nechodis na prednasky, vsak?
nemaj boj, aj moje nevyplo cele v 2-ke. Riesil som to surovo funkciou Exit. ale exit zase nesmies pouzivat v tom co posles

pred ustnou skuskou u Hudaka

horor-jedine stare kusky, tie nove uz su namiesto napinave, nechutne...

co to je?

vsak nejaky problem.. ale my nemame problemy

ok vdaka

btw: stratil as mi disk, co teraz?

pouzivaj magnetofonove pasky

neviem co znamena priamo transparentne mne je jedno kto to spravi len aby to bola kvalita

OT: znamienku ^ sa po slovensky spravne povie umocnovanie?

hej, ak myslis to... lebo ten znak moze znamenat napriklad aj logicky sucin...

ja som mylsle ze Xor

nech si preinstaluje operu a ma pokoj, nie je co riesit...

podla teba vie co toje preinstalovat? ak ani shift nenajde?

[.intValue()]

skus

ShutdownListener shut = new ShutdownListener(this, Integer.parseInt(this.myprops.getProperty(IConstants.SHUTDOWN_PORT)).intValue(), this.myprops.getProperty(IConstants.SHUTDOWN_PASSWORD));

tak to ma byt ale bez toho .intValue() na konci...

joj fakt. som nevsimol len pastol povodny a som upravil

a teraz neviem ci je PC  zapnute alebo vypnute ked uz nepradie 

skus pozret LEDku na bedni, alebo ak mas obraz na monitore, tak to zvycajne indikuje zapnute pc 

    37.     ShutdownListener shut = new ShutdownListener(this, new Integer(this.myprops.getProperty(IConstants.SHUTDOWN_PORT)).intValue(), this.myprops.getProperty(IConstants.SHUTDOWN_PASSWORD));
   

skus

ShutdownListener shut = new ShutdownListener(this, Integer.parseInt(this.myprops.getProperty(IConstants.SHUTDOWN_PORT)).intValue(), this.myprops.getProperty(IConstants.SHUTDOWN_PASSWORD));

Tha,... adresovanie 32 bitmi povoluje 4 GB. ale uz to teraz dajak nefunguje ako v zlatom '86 .
(vtedy sme vystacili s 64KB)

a necuduj nad predavacmi. Ja som kupoval pred par dnami 512-ku ram, taku istu ako mam v stroji, aby som zapol dualchannel.
On mi tam ten predavac hovoril, ze nestaci mat rovnake velkosti a rychlosti modulov, ale musi byt rovnaka seria. No , ne mal pravdu 


edit - tu prihou som zazil par krocikov od imperio, nie v imperio

...

skus najst chybu tak, ze das vypisovat pred a po riadkoch, ktore sa ti zdaju, ze mozu robit chybu. Lachsie najdes chybu. alebo debugni niekde v niecom

neverím, že to tam nemáš alebo spúšťaš niečo iné ako kompiluješ

vazne nemam. Nikde vo vytvaranych suboroch to nemam. Ani ShareMeImpl ani ShutdownListener. a kompilujem/spustam pomocou ant lab1 a ant run1... Som rozmyslal ze sa dneska na cviku na ten paranormalny jav opytam Paralica, ale myslel som ze to robi aj inym. Kedze iba mne tak sa ho najblizsie opytam...

Joj boze. Ty co pises ako zadanie je asi tak 40% toho co program skutocnosti robi (mozno aj menej)
v ShareMe.jar mas uz zrobenu zvysnu cast, teda tam ti to vypisuje, co si ty nenapisal. Nemaj haluze z toho.

Nemtom - skus teraz stiahnut tie balicky shareme (vyber z toho len build.xml - a nahrad svoje na konte) ze vraj tam bola drobna chybicka.
a to classpath (vtedy mozno netreba ten novsi build.xml) - tie riadky napis na koniec suboru .tcshrc  (tu mas v adresari kde sa ocitnes po prihlaseni)

.tchs? wtf?

citujem

Ak sa z nejakých dôvodov rozhodnete Ant nepoužívať, potom môžete využiť nasledujúci tcsh skript ako časť vášho kódu spúšťaného pri prihlásení (.tcshrc):


# nastavenie vnutornych premennych pre dalsie pouzitie
setenv JAVA_HOME /opt/j2sdk1.4.2
setenv ANT_HOME /usr/share/ant


# nastavenie premennej PATH
setenv PATH ${PATH}:${JAVA_HOME}/bin:${ANT_HOME}/bin


# nastavenie premennej CLASSPATH
setenv CLASSPATH .:${CLASSPATH}:${ANT_HOME}/lib/ant.jar
setenv CLASSPATH .:${CLASSPATH}:${HOME}/lib/ShareMe.jar:${HOME}/classes


# nastavenie JIKESPATH
setenv JIKESPATH ${JAVA_HOME}/jre/lib/rt.jar:${CLASSPATH}

Pravda, ze aj ja pouzivam ten ant, ale pokym som toto nezrobil , aj mne hadzalo classnotfound (?)
mozno po modifikovani treba logout/login
