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
Mike

Could 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

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:

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:

The only thing I could see different between the discovery packets were the id and the source port - so I'm really puzzled as to what could be going on here!
Do you have any ideas? And does this change your percentage probabilities at all?!

"None of your preferred networks are available" But they are!

This is the one problem that most bugs me with my MBP, i was hoping that 10.5.2 would fix it, but it does not.
I use my MBP on two wireless networks. They are both airport expresses with different SSIDs.
The first (work) is one airport express and my MBP will connect to it when ever it is in range happily. The second (home) is an airport express with another airport express extending the first. The only one in range on my laptop is the extension. Every time I wake the laptop it will tell me that "None of your preferred networks are available" and show the name of my network in the list - it has the password stored and has been told to remember the network... and yet it still refuses to connect.
Clicking the network shows that it knows the password as it displays it. I have rest both airport expresses and made the network from scratch, I have also deleted all references to the network in keychain and airport preferences, and yet it still does it.
There are a couple of other threads on this topic, but none of them have been resolved (That i have found) and they seem to have a slightly different problem to me, so I have posted my own question.
Does anyone know what is wrong?
Thanks.

I don't have the answer, I have the problem...
I'm also in one of the other threads about 10.5.2 messing up connection to my Apple Airport Extreme (melted marshmallow), but I also have the "None of your preferred networks are available" problem.
My network configuration looks like this: http://tijil.org/LAN_06.jpg
I have: Hard reset Airport, re-loaded firmware, re-done all settings, powered up and down numerous times, changed channels, etc. to no avail.
For me the Airport Base continues to work just fine with the other two computers connected to it wirelessly, but my 3 week old MacBook with 10.5.2 will no do so automatically, and once it does, even though the signal is strong and the S/N ratio is good, the connection is usually much slower than either of the other machines, has difficulty sustaining a large upload, and frequently drops out - for the MacBook only.
This did not happen with 10.5.0 or 10.5.1 and does not happen with the machines running 10.4.x.
The Airport Extreme Base is set to use 802.11b/g as one of the older machines can only handle 'b'...
I have MAC screening set up and also WAP. Network is NOT 'hidden.'
Airport Utility on the MacBook also has difficulty finding the base even when the MacBook is actually connected to it and using it to download mail. sigh
The problem is something that changed in 10.5.2.
Hope Apple gets this sorted soon!

Network Scan: IP "AND" AD OU Search

i dont think so. the entry has to be either an ip address or an OU.

Is it possible to have the network scan function require two search criteria?
I would like to scan for computers that are both in a specific OU in Active Directory as well as a specific IP range. Is this possible? One example is that we have an OU that includes systems from different locations. Each location has their own SW server. So, I would effectively like to do an AND function in the search.

What is up with Apple's Network not supporting Network scanning and even Ne

Hello.
I have a HP 3210 Network printer/scanner. After upgrading from my LinkSys router to a Time Capsule I now find that my HP Network scanning capability is dead. Apple tech support has admitted that they don't support scanning nor even some network printers on the Time Capsule, airport & Airport express. Apple won't even give me enough details on the issue so I can talk intelligently with HP???
What is up with that? That is completely unacceptable. I can print to my printer, I can browse the built-in web server (and scan interestingly enough using the web server), but when you try and run the HP scanning client it indicates it can't communicate with the printer/scanner.
Any ideas out there? I'm really disappointed.

What is the deal here?
Easily explained: On or about 24 July the entire discussions.apple.com web site was moved to servers running Windows Vista Enterprise OS. The site was compromised approximately 6 seconds later by a group of Romanian hackers believed to be funded by Nigerian Internet scammers who had millions of dollars in credit to play with when hundreds of thousands of victims sent them their credit card numbers to pay what they thought were nominal fees to get some of the 100,000 missing iPhones sold the first week but according to AT&T never activated. Supposedly, a malfunction in a mail router or address machine (the story varies) inadvertently sent all these phones to a mid-ranking Nigerian official who needed financial assistance with getting them out of the country.
Well, either that or the site is still controlled by Apple & has been undergoing extensive changes which, shall we say, have not yet been completely sorted out, much in the same way that Iraq has not ....

Advice on how i can set up an office network with 40 computers.

I am planning on setting up an office network with 40 computers. What do you think is the best way i can do this? Thank you in advance.

Your first step should be to call an IT professional who has experience with this type of thing. He will need to survey the entire area and ask you dozens of questions about how you want things to operate. Then, he will present you with a proposal for the network listing all of the things that the system can and and cannot do.
Your second step would be to call another IT professional who has experience with this type of thing and go through the same procedure.
Your third step would be the same as the first and second.
Your fourth step would be to check the references provided in the steps 1-3 and then decide on which professional that you want to use.

Canon iR2520 Network scan gear

Hi guys, I face problem with canon iR2520 Network Scan gear. The scanner works from platten glass to scan pages one by one. but it doesn't work from ADF feeder to scan multiple page. it displays "no original in the feeder"
even if there is paper to scan or sometimes it displays an error "jam in the feeder". please help me I am waiting for your reply.
Thank you.

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 Lawrence

When 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.

Network scan not working

I have a wrt54g-tm router and a Dell 1815dn multifunction networked printer.
Before I was using a Netgear router and everything was working fine.
Now I can print over the network (the 1815dn is plugged directly into the router via Ethernet) but I cannot set-up the network scan. I have updated the firmware for both the router and printer and uninstalled/reinstalled the printer drivers multiple times. When I attempt to set up the network scan using the dell wizard it finds the printer on the network but then I get "unknown error please check your network connections"
...HELP

There was a firmware update for this printer just 2 days ago, please goto support.dell.com click on driver and downloads, enter the service tag of your printer and click go. at the bottom of the page click on the plus sign to expand you download options, then download the firmware update to your desktop. follow the instructions to update your printers firmware.
This is a large update (11 megs) and installing it can take about a half hour. do NOT power off your printer during the update!!!
if your printer says updating flash or installing update, just let it sit.
again this can take a looong time so DO NOT power off during this.
after the update is installed the printer will restart itself.
this should solve your problem.
cheers

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,
Allen

Hey 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 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....

None of your preferred networks are available

Hi,
I'm still having this problem. Whenever I turn my Leopard running iMac on, as soon as the Desktop loads a message pops up saying:
"None of your preferred networks are available"
The SSID name of my home WiFi network is visible in the list of available networks, but when I try to join it I get the message:
"Connecting to network"
and then
"Connection timeout"
This problem isn't exclusive to my Tiger upgraded to Leopard iMac. It's exactly the same on a brand new late 2007 MacBook with Leopard pre-installed!
WiFi used to work flawlessly with Tiger. But with Leopard it's very unreliable to the point of being unusable. When are Apple going to sort it out? Nothing has changed with my Netgear DG834PN Router. It's setup exactly the same way it was with Tiger.
Any help would be appreciated.

Reuben,
You're not alone. I have the same problem, and literally tons of other people do too. After running my search on apple discussions for "preferred networks" (my results url is: http://discussions.apple.com/search.jspa?forumID=599&threadID=&q=preferrednetworkproblem&objID=c235&dateRange=all&userID=&numResults=30&rankBy=10001 ) and finding 236 responses, it seems patently clear that the problem is a bug in Leopard.
I filed a bug report at bugreport.apple.com, and was given the "Problem ID" of: 5692458. My description, following Apple's requested protocol, may be found at https://bugreport.apple.com/cgi-bin/WebObjects/RadarWeb.woa/27/wo/ZC6cutwkbBEtt3 M1MEp67M/7.21
and other posters have recommended that as many others as possible do the same.

Network Accounts Available Indicator

I need to better understand the "Network Accounts Available" indicator light. We have eMacs and put in new Cisco GB switches. When we start from a cold boot, it usually takes about 3 -4 minutes for this indicator light to turn from red to green. If I turn AFP off on the XServe, it still takes the same amount of time for this indicator light to change but if you try to log in, you cannot do it because AFP is turned off. I understand that the users cannot login because AFP is disabled. We tried to force the switch and the workstation to 100baseTX / full-duplex and there were not any consistent changes in time.
So my question is, what exactly is it telling us? Is it the time it takes to establish a connection from the eMac to the server? Is it the amount of time it takes to auto-negotiate to the first switch that it is connected? Is it an issue that the NIC card is having trying to auto-negotiate with a Gigabit switch? I really need some input because we are starting to put more Gigabit switches in our schools and we still have a lot of eMacs.
All responses are more than welcome.
Our hardware is:
eMacs - OS 10.4.6 - 10.4.11, 256 or 512 MB RAM, 1GB PPC processor
Switches - Cisco 3560, 4500, & 6500
Server - OS 10.4.11, 2 GB RAM, PowerPC G4 processor

Is the Ethernet Interface dragged to the top of Network>Show:>Network Port Configurations? That is the search order for connections.
Do you have proper DNS Servers & Search Domain entered in the Network>TCP/IP tab for Ethernet?
