How to speed up Network Scans?
Howdy,We are just starting to use the Spiceworks Help Desk so I figure dI might as well take a look at the Network Scanning functionality as well. I went in and setup my various IP ranges and kicked off a scan. The scan seems to be working but seems like it's going to take forever. I'm wondering what the best way might be to try to speed things up.Spiceworks is installed on a VM running Server 2012 R2. 2 Cores, Dynamic memory, and it's running on clustered Netapp FAS drives.We have 200-250 various workstations (laptops, surfaces, etc)
We have another couple hundred servers (mostly VMs)
We also have 2 people who work the Help Desk tickets all the time and another 4-6 that work them if the first level people need help
I see there are a lot of various scan types that can be scheduled but I don't know which ones are or aren't resource hungry....

How to properly locate and "Uninstall Canon ij Network Scan Utility"
I had this same problem so I went thru my computer's specifics.
If you try doing a spotlight or "find" search for canon, canon lj network utility, etc. you'll only find a "Canon" folder, but it won't necessarily give you the information you're looking for.
Here's what I did:
First turn off the "canon ij network scan utility"
Then:
1. Click on Finder
2. Click the Macintosh HD icon (hard drive icon under iDisk)
3. Click the Library folder (make sure it's the folder with the picture on it, building with columns)
4. Scroll down to the "Printers" folder
5. Locate the "Canon" folder, then the "BJPrinter" folder.
6. Once you installed the "canon ij network scan utility" to your computer, various components will be scattered throughout this "BJPrinter" folder. Click on each folder, and check the "Date Modified" column. Every file within this folder that has a Date Modified similar to the date you installed the program, is a file with a relation to the "canon ij network scan utility." I suggest deleting them all.
7. If you're looking to make sure you're getting rid of the"canon ij network scan utility," after you click on Macintosh HD>>Library>>Printers>>Canon>>BJPrinter, click on the "Utilities" folder. In this folder you'll find a couple of utilities installed with the "canon ij network scan utility" program, but you'll also find the actual "canon ij network scan utility" program. I suggested dragging the utilities folder to the trash and disposing of it all. Do a "secure empty trash" if necessary. It may not empty right away since you still had it on the top right, so restart your computer then try to empty the trash when everything reboots.
Hope this helps.Under System Preferences, System, Accounts, Login Items, I removed the Scan Utility from the list of programs that open automatically when I log in. The program no longer starts but I fear that the program is lingering some where on my computer hard drive.

Canon MP600R WiFi Network Scan/Print Failure
Hi there
My setup:
* a Canon MP600R multifunctional printer/scanner
* an Apple iMac running Snow Leopard
* a Dell Laptop running Windows Vista, and
* a Netgear WGT624v3 wireless router.
The printer and the two computers are all wirelessly connected to the router - there are no USB cables or wired LAN connections being used between these machines. All the machines have statically configured IP addresses (printer included).
I can print and scan reliably from/to the Windows laptop. Printing from the Mac used to work reliably, but scanning to/from the iMac only worked once in a blue moon.
To try to fix this, I updated the drivers on the Mac to the latest versions for Mac OS X 10.6 (Snow Leopard), and now I can't print or scan at all. The software I've been using is:
From Canon Europe:
* mp600rosxcp102620ea8-2.dmg - CUPS Printer Driver for OSX (10.26.2)
* mp600rosxns10ea7-3.dmg - MP Drivers for Network (Snow Leopard) (1.00)
* mp600rosxsd12131ej7.dmg - ScanGear CS for OS X (12.13.1)
* mpnosx304ej7.dmg - MP Navigator- MP Navigator for Mac OS X (3.04)
From Apple:
* CanonPrinterDrivers2.3.dmg - Apple's Canon Printer Drivers (http://support.apple.com/kb/DL899)
From Canon Australia:
* ntosxm270ea8-2.dmg - IJ Network Tool Ver. 2.7.0
After many delete/reinstall steps on the Mac (following PAHU's advice!) and much Googling - including disabling/enabling firewall settings, IPv6 settings and even various router RIP settings - I could do with some help please!
What appears to be happening is that the Mac can't 'see' the printer, whereas the PC can - the drivers all seem to be installed in a similar way, and once set up (using the one-off USB connection step that the installers seem to like) they all have the right MAC address info. However the Mac Network Scan Utility shows a warning next to the printer's MAC address, whereas the PC is happy. Likewise, the PC's printer utilities can tell me about ink levels, the Mac's one gives me a communication error and puts the printer into paused mode.
This leads me to believe it was something going on on the network. I can, however, ping the printer from the Mac and access it's web configuration interface - so it's not that the printer's unreachable from the Mac.
To try to see what was going on in a bit more detail, I installed Wireshark and did some captures of the use of the Network Tool and Scan Utility.
On the PC (192.168.0.4), which works, it appears to direct the BJNP discovery commands direct to the printers IP address (192.168.0.2).
On the Mac (192.168.0.5), which fails, it appears to be broadcasting BJNP discovery messages to the subnet (192.168.0.255) and receiving ICMP Parameter problem responses from the printer.
So, is this likely to be:
A. the Canon drivers on the Mac
B. the Netgear router doing something to stop the broadcast discovery, or
C. something in the printer firmware?
If so, any ideas how to workaround it - for example, can I 'force' the Mac version of the drivers to not do broadcast discovery and simply go direct to the IP address like the PC?
Any help, pointers, gratefully received!Hi PAHU
Thank you very much for responding - particularly with such detailed and reasoned advice!
I have just tried deleting the BJPrinter folder, restarting and reinstalling only the Apple Canon Printer Drivers 2.3. On opening Print & Fax -> Add Printer I don't see anything in the window (no Bonjour Scanner or canonijnetwork) - I have left it open for more than 20 minutes now and still nothing.
Using wireshark, I can see the Canon BJNP Discover packets to both 8611 and 8612 (and some mdns and db-lsp-disc packets). I can see the printer responding with error responses too:
45620 12463.295007 192.168.0.5 192.168.0.255 canon-bjnp1 BJNP Printer Command: Discover

This pattern repeats every 8 seconds or so for the scanner and roughly every 25s for the printer port.
This extract (while typical of what's happening now) was actually taken from a lengthy capture I made yesterday which shows that, after quite a long period of time, it suddenly starting to work. This fits with my previous experience of seeing it 'coming and going' very intermittently (e.g. when leaving Add Printers open for an hour or more). When it started working it looked like this:

Canon IJ Network Scanning Utility not showing up in Menu bar
Hi, I recently performed an erase and install of my Mac. I then used Migration Assistant to restore my data. I have a Canon MP620 Wireless Printer. I noticed that the Canon IJ Network Scanning Utility is not showing up in the menu bar. How do I get it to show up again?
Message was edited by: Stuart LawrenceWhen installed, the Canon IJ Network Scan Utility is located HD > Library > Printers > Canon > BJPrinters > Utilities. Double click the utility and the icon will appear on the menubar. If you want the utility to start on login, then you can add it to your Login items, located in System Preferences > Accounts.

starting Mac book pro become very slow about 4 minutes. How can I speed it?
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utility is: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption. Drive Genius provides additional tools not found in Disk Warrior for defragmentation of older drives, disk repair, disk scans, formatting, partitioning, disk copy, and benchmarking.
Four outstanding sources of information on Mac maintenance are:
1. OS X Maintenance - MacAttorney.
2. Mac maintenance Quick Assist
3. Maintaining Mac OS X
4. Mac Maintenance Guide
Periodic Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) SeeMac OS X- About background maintenance tasks. If you are running Leopard or later these tasks are run automatically, so there is no need to use any third-party software to force running these tasks.
If you are using a pre-Leopard version of OS X, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced after Tiger. (These utilities have limited or no functionality with Snow Leopard, Lion, or Mountain Lion and should not be installed.)
Defragmentation
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive except when trying to install Boot Camp on a fragmented drive. But you don't need to buy third-party software. All you need is a spare external hard drive and Carbon Copy Cloner.
Cheap and Easy Defragmentation
You will have to backup your OS X partition to an external drive, boot from the external drive, use Disk Utility to repartition and reformat your hard drive back to a single volume, then restore your backup to the internal hard drive. You will use Carbon Copy Cloner to create the backup and to restore it.
1. Get an empty external hard drive and clone your internal drive to the
external one.
2. Boot from the external hard drive.
3. Erase the internal hard drive.
4. Restore the external clone to the internal hard drive.
Clone the internal drive to the external drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not depressed or is ghosted.
5. Click on the Clone button.
Destination means the external backup drive. Source means the internal startup drive.
Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive and click on the upward pointing arrow button.
After startup do the following:
Erase internal hard drive
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your internal hard drive (this is the entry with the
mfgr.'s ID and size) from the left side list. Note the SMART status of the
drive in DU's status area. If it does not say "Verified" then the drive is
failing or has failed and will need replacing. SMART info will not be
reported on external drives. Otherwise, click on the Partition tab in the
DU main window.
3. Under the Volume Scheme heading set the number of partitions from the
drop down menu to one. Set the format type to Mac OS Extended
(Journaled.) Click on the Options button, set the partition scheme to
GUID then click on the OK button. Click on the Partition button and wait
until the process has completed.
Restore the clone to the internal hard drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not selected or is ghosted.
5. Click on the Clone button.
Destination means the internal hard drive. Source means the external startup drive.
Note that the Source and Destination drives are swapped for this last procedure.
Malware Protection
As for malware protection there are few if any such animals affecting OS X. Starting with Lion Apple has included built-in malware protection that is automatically updated as necessary.
Helpful Links Regarding Malware Protection:
1. Mac Malware Guide.
2. Detecting and avoiding malware and spyware
3. Macintosh Virus Guide
For general anti-virus protection I recommend only using ClamXav, but it is not necessary if you are keeping your computer's operating system software up to date. You should avoid any other third-party software advertised as providing anti-malware/virus protection. They are not required and could cause the performance of your computer to drop.
Cache Clearing
I recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc. Corrupted cache files can cause slowness, kernel panics, and other issues. Although this is not a frequent nor a recurring problem, when it does happen there are tools such as those above to fix the problem.
For emergency cleaning install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. (AppleJack works with Snow Leopard or earlier.)
Installing System Updates or Upgrades
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Backup and Restore
Having a backup and restore strategy is one of the most important things you can do to maintain your computer. Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner.
2. Deja Vu
3. SuperDuper!
4. Synk Pro
5. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance and backup and restore.
Always have a current backup before performing any system updates or upgrades.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity or 20 GBs, whichever is greater, as free space. Avoid installing utilities that rely on Haxies, SIMBL, or that alter the OS appearance, add features you will rarely if ever need, etc. The more extras you install the greater the probability of having problems. If you install software be sure you know how to uninstall it. Avoid installing multiple new software at the same time. Install one at a time and use it for a while to be sure it's compatible.

ISE 1.x profiler question (Network Scan Action & Exception Action)
Could someone please explain the following based on this scenario:
Say you create a Profiler Policy called “DeviceBrandX” and you set the Minimum Certainty Factor to 20 and you create a condition to profile based on a check for condition based on host-name in DHCP and you assign the condition a Certainty Factor Increases of 10. In additoin you define an Exception Action and a Network Scan (NMAP) Action in the policy.
Here are the two questions:
If you create another condition that initiates a scan Network Scan (NMAP) Action to scan say for OS - how does the scan influence the Certainty Factor?
Also if you create a condition that initiates Exception Action - how does that influence the Certainty Factor?
Thanks,
AllenHey Tarik,
Thank you for the response; I have looked at the apple-device policy, I see that the “* Exception Action” field is = NONE. I only see that the Network Scan (NMAP) Action is set to OS-scan. In fact I have looked at all the generic policies and none have an “* Exception Action” field set.
I can see that under the Rules configuration you can set the rule to "Take Exception Action" but in the top part of the configuration the "* Exception Action” there is no selection option.
I am assuming if you wish to trigger and event you would identify the event in the “* Exception Action” field and under the rule you would select "Take Exception Action". How do you configure the “* Exception Action” to determine which Action to take?
Thanks,
Allen -
How to speed up the BEA weblogic workshop perforkmance?
Hi,
Does anybody knows how to speed up the BEA weblogic workshop,as it consumes heavy memory.
I've configured the settings in workshop.cfg file and set the maximum memory size as 1024m midium size 516m and minimum size as 256m
and deleted all the files from .workshop directory before open up the workshop file.
But it hanging up the system when i opened the worshop file after some time. what could be the problem . i am using 2GB ram sizeHi Vishnu,
I agree this can also be one of the reason for the performance. There is Trend Micro Office Scan client installed on my system, but i couldn't not do any settings ,as it is disabled by sys admin .
however, i removed all the scanning processes from task manager and set the high priority for the java process! still, no improvement. There are only few jpd files not even 500kb size, but when i open them, weblogic cried and utilized lots lots of memory! :-(
I am afraid to open the weblogic which had jpd files,as it hanged my whole system, unable to perform any other tasks! -
How to setup Guest Network Name in Cisco Router
Hello everyone!
The first. Sorry my english =)
I want tald you how to change guest network name in cisco (what have different name)
What we need.
1. Cisco Connect for Mac OSX (i use snow leopard and Cisco Connect for E3000)
2. Terminal
Okay. Let's go.
1. Install Cisco Connect for OSX
2. After setup - slighty setup your cisco router (give something name and password), then, when cisco connect say you "You now connected the internet" and going to main screen - exit from cisco connect
3. Open Terminal (Or you can use Finder (go to Application, show package content Cisco Connect))
4. Go to /Application/Cisco Connect.app/Contents/Resources/lcid/<your setup language, for english - go 1033>/
5. Edit resource_strings.pus (vi resource_strings.pus)
6. Change "-guest" in string <LocalizableString RcFileId='10019' BaseTextHash='0xA65E286D' BaseText='-guest'/> for something what you want. For example, i changed for ' Guest Network'
7. Save
8. Open Cisco Setup
9. Go to router configuration and change desired name. I changed to 'Grizlly Bear'
10. After setup name - go to Guest Setting and Enable. As you can si, your guest network name set as 'Grizlly Bear Guest Network'
11.Exit Cisco Setup
12. Go to web interface setup
13. Setup Wifi manual and change SSID for diferent names. I change 5Gh to 'Grizlly Bear Hi-Speed Network' and 2.4GHz to 'Grizlly Bear Main Network'
14. Setup your hostname for all services (fileserver, media server, etc)
Woala!
We have three diferent names network!
Questions?In order to enable Guest networking, the AirPort Extreme must be configured as your "main" Internet router. In this configuration, Connection Sharing = Share a Public IP address. The Extreme would be connected directly to the Internet modem and NOT downstream of another router with NAT enabled.
In this configuration, the Guest network would provide access ONLY to the Internet and NOT to your LAN. -

How to speed up my computer? Basic configuration is as below.
Intel Pentium Dual Core 2.5 GHz Processor
Ram: 2GB
HD: 350 GB
Mother Board: Giga Byte
OS: windows XP
I am using Office2007 in my PC. I have enable firewall. Can I disable it? If so, then how to protect my pc from virus attack?There are a lot of different things you can do to speed up your PC. First off, try to upgrade your ram, You can Google your motherboard model to see how much and what kind it can hold. Or go to www.crucial.com and run the analyzer that scans your system and tells you what kind and how much ram your PC can handle. You can get ram dirt cheap these days especially if you order it online.
Next you should uninstall any unwanted or unused programs, there is a very good uninstaller called Revo uninstaller, it is free. It removes programs and then scans for registry and other left over files from the PC. Or you can just go to control panel---add or remove programs and do it from there. And while your there you can go to add or remove windows components and disable anything that you don't use.
Click start click run the type "msconfig" (without the "") under the startup tab uncheck anything that is not necessary to run at startup. This will make your PC boot faster.
If you go to www.blackviper.com/WinXP/servicecfg.htm they have a complete guide to disabling unneeded services on a 32 bit windows XP PC. There are a lot of services that you will never need or do not use. Make sure you click on each service you are thinking about disabling and read what it is first. You don't want to disable anything you need on accident.
I use CCleaner to clean, defrag and compress the registry. There are other free and paid programs out there to tidy up your registry which gets a lot of errors and unnecessary entries in it every time you use your PC.
When you store a files on your PC they get fragmented and this slows your system down. Again there are a lot of free programs to defrag your hard drive. I use Ultimate Defrag. With this program you can place your most used files(windows files etc) on the outer rows of your hard drive (fastest part) and the least used files or archive files on the inner rings. It gives you many options to defrag as well as just simple defrag.
I would keep the firewall on or get a third party one. I don't know what anti virus you use but there are numerous reviews and guides online as to which ones are the fastest and have the lightest footprint. I use Esset, but there are a few good free ones also. If you think you have a problem with a virus or malware download and run superantispyware pr malwarebytes, and use it alongside of your anti virus.
Go to your local bookstore and look at the PC magazines. A lot of them have good tips to make your PC run faster and some come with free CDs that have a lot of freeware/shareware programs on them.
Hope this helps -
Uninstall Canon IJ Network Scan Utility
I recently attempted to install the Canon MX700 over a wired LAN but was unsuccessful. I was so fed up that I decided to uninstall all the software associated with Canon. I still see an icon for the Canon IJ Network Scan Utility in the upper right hand portion of my screen. How can I ensure that all the software associated with Canon is removed?
Thanks.Under System Preferences, System, Accounts, Login Items, I removed the Scan Utility from the list of programs that open automatically when I log in. The program no longer starts but I fear that the program is lingering some where on my computer hard drive.

How to setup wired network with G4, MBP and PC
Sorry to ask a bit of a stupid question here, but I've never had to network machines together so I'm starting from a knowledge level close to zero.
Situation. Old G4 (733) and new (intel) Mac Book Pro in one room. New PC (Dell) in another room with a wired router connected to internet. PC is also connected to a laserprinter. Hard wire ethernet cable running between the rooms to connect either the G4 or the MBP to the internet. Both the G4 and the MBP have only one ethernet connection. MBP is wireless, as is the PC. The G4 is not.
First off, I'd like to network the MBP and the G4. I believe ethernet is the best way to do this, but if I do that, how would I then connect to the internet? Would I just have a second router in the Mac room with the 2 Mac's hooked up to it and the other end going back to the router that's connected to the internet? I'd rather stay hard-wired than go wireless if at all possible. I do most of my internet work through the MBP, but some must be done through the G4, ie software updates, as the G4 has a lot more programs on it.
Second question, how would I then network to the PC in the other room? It would be nice to move files, photographs for instance, between the Macs and the PC. I'd also like to access the lazerprinter which is in that room, connected to the PC.
Hoping this is a simple question with a simple answer.
Thanks!Hi-
Welcome to Discussions!
What you are describing is all possible, but, I am going to assign you some reading. This way, you'll be able to deal with your own particular needs, like a Pro.
The following will get you up to speed on networks, and various hardware needed:
http://www.atpm.com/network/setup/index.html
http://compnetworking.about.com/od/homenetworking/HomeNetworking_Setting_Up_a_HomeNetwork.htm
http://www.apple.com/support/tiger/network/
Adding the PC into the network has some special considerations. the following sites have good info for setting up such a network:
http://www.mac-connect.com/
http://www.apple.com/business/mac_pc/tutorials.html
For my needs, I have a switched ethernet network. All computers are connected to the switch, as is the modem, by ethernet cable. This allows computer to computer networking using AppleTalk. With the same cabling and switch, the computers are all able to connect to the internet using DHCP, or, one at a time using PPPoE.
These are all Mac's, but, with some setting adjustments, a PC can also be placed in a similar network.
As well, adding a wireless connection for one computer is possible. This would require a wireless base station to be connected to the switch. The wireless capable computer would then be able to enter the network, and vice-versa. Of course, the settings for all the hardware and software are the key. The settings can have variables, depending on what is connected, and how the connections are made. Another variable is your router/modem, and your internet service providers policies on multiple connections.
Adding the printer depends on the capabilities of the printer. Often, it is only possible to share a printer through a computer. A network capable printer can be connected to the switch, directly, or to a wireless base station, and then shared by all on the network.

Kappy's Personal Suggestions About Mac Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utility is: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption. Drive Genius provides additional tools not found in Disk Warrior for defragmentation of older drives, disk repair, disk scans, formatting, partitioning, disk copy, and benchmarking.
Four outstanding sources of information on Mac maintenance are:
1. OS X Maintenance - MacAttorney.
2. Mac maintenance Quick Assist
3. Maintaining Mac OS X
4. Mac Maintenance Guide
Periodic Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) See Mac OS X- About background maintenance tasks. If you are running Leopard or later these tasks are run automatically, so there is no need to use any third-party software to force running these tasks.
If you are using a pre-Leopard version of OS X, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced after Tiger. (These utilities have limited or no functionality with Snow Leopard, Lion, or Mountain Lion and should not be installed.)
Defragmentation
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive except when trying to install Boot Camp on a fragmented drive. But you don't need to buy third-party software. All you need is a spare external hard drive and Carbon Copy Cloner.
Cheap and Easy Defragmentation
You will have to backup your OS X partition to an external drive, boot from the external drive, use Disk Utility to repartition and reformat your hard drive back to a single volume, then restore your backup to the internal hard drive. You will use Carbon Copy Cloner to create the backup and to restore it.
1. Get an empty external hard drive and clone your internal drive to the
external one.
2. Boot from the external hard drive.
3. Erase the internal hard drive.
4. Restore the external clone to the internal hard drive.
Clone the internal drive to the external drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not depressed or is ghosted.
5. Click on the Clone button.
Destination means the external backup drive. Source means the internal startup drive.
Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive and click on the upward pointing arrow button.
After startup do the following:
Erase internal hard drive
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your internal hard drive (this is the entry with the
mfgr.'s ID and size) from the left side list. Note the SMART status of the
drive in DU's status area. If it does not say "Verified" then the drive is
failing or has failed and will need replacing. SMART info will not be
reported on external drives. Otherwise, click on the Partition tab in the
DU main window.
3. Under the Volume Scheme heading set the number of partitions from the
drop down menu to one. Set the format type to Mac OS Extended
(Journaled.) Click on the Options button, set the partition scheme to
GUID then click on the OK button. Click on the Partition button and wait
until the process has completed.
Restore the clone to the internal hard drive
1. Open Carbon Copy Cloner.
2. Select the Source volume from the left side dropdown menu.
3. Select the Destination volume from the left side dropdown menu.
4. Be sure the Block Copy button is not selected or is ghosted.
5. Click on the Clone button.
Destination means the internal hard drive. Source means the external startup drive.
Note that the Source and Destination drives are swapped for this last procedure.
Malware Protection
As for malware protection there are few if any such animals affecting OS X. Starting with Lion, Apple has included built-in malware protection that is automatically updated as necessary. To assure proper protection, update your system software when Apple releases new OS X updates for your computer.
Helpful Links Regarding Malware Protection:
1. Mac Malware Guide.
2. Detecting and avoiding malware and spyware
3. Macintosh Virus Guide
For general anti-virus protection I recommend only using ClamXav, but it is not necessary if you are keeping your computer's operating system software up to date. You should avoid any other third-party software advertised as providing anti-malware/virus protection. They are not required and could cause the performance of your computer to drop.
Cache Clearing
I recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, Mountain Lion Cache Cleaner 7.0.9, Maintenance 1.6.8, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc. Corrupted cache files can cause slowness, kernel panics, and other issues. Although this is not a frequent nor a recurring problem, when it does happen there are tools such as those above to fix the problem.
If you are using Snow Leopard or earlier, then for emergency cleaning install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. (AppleJack works with Snow Leopard or earlier.)
Installing System Updates or Upgrades
Repair the hard drive and permissions beforehand.
Update your backups in case an update goes bad.
Backup and Restore
Having a backup and restore strategy is one of the most important things you can do to maintain your computer. Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. You can never have too many backups. Don't rely on just one. Make several using different backup utilities. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance and backup and restore.
Always have a current backup before performing any system updates or upgrades.
Final Suggestions
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity or 20 GBs, whichever is greater, as free space. Avoid installing utilities that rely on Haxies, SIMBL, or that alter the OS appearance, add features you will rarely if ever need, etc. The more extras you install the greater the probability of having problems. If you install software be sure you know how to uninstall it. Avoid installing multiple new software at the same time. Install one at a time and use it for a while to be sure it's compatible.

Most if not all maintenance is for troubleshooting problems. If your computer is running OK, then there isn't really a thing you need to do except repair the hard drive and permissions before installing any new system updates. -
Network scan - available computers
How do I perform a network scan to obtain what computers a re available on a local TCP/IP network? I mean something like "net view".I'd like to optionally specify a domain to search like in "net view /domain:MyDomain". The IPs of course differ only in the last byte 111.111.111.* for example.
Thanks in advance
MikeCould you be more specific? What should I use to implement this scheme?
Do I need an application running everywhere?
Related question:
Is there an easy way to check if an IP is available on the local network /for example just loop from 0..255 the last byte and ask each of them all to reply/? In that case how should I access the remote computers and what will give me the status /is a machine with that IP running or not/?
Of course the easiest thing I could do is use the runtime to create process executing the prompt command and processing the output but I prefer a pure solution.
Thanks in advance
Mike
