Correct! Thanks @DPUP5520 and @Rcrsn51 for correcting that. I forgot about a intranet page that I have on this internal network I'm on.

I do have a poor memory but as I remember my Windows had one version of Java and then when I wanted to use it for a program needing it then them told me to change to another companies Java.

So it was not just another version of the same company but a totally other Java that was supposed to be better than the one included in the OS?

nooby are you sure you aren't thinking of openjdk?

Win9x came with Microsoft's own JVM, but they were sued by Sun for not fully implementing the Java standard. MS lost and quit including Java by 2003.

Its really obvious for most on how to scan your LAN using AngryIP.. Straight away easy!

But, Its not obvious to some, how to use AngryIP for port scanning. Here's something that some may find useful for Port scanning

But be careful because a large IP range and large port ranges will elongate the time it takes the utility to report its finding on-screen.

Hope this helps

DPUP5520 no I was not thinking about that one. I trust that
rcrsn51 gave a good answer. Sun was involved.

Trying to stay on-topic for this thread. JAVA is a separate topic and is only mentioned to indicate requirements "for AngryIP V3" products.

If you want to understand how MS integrates JAVA (whether its MS-SUN integrated in the OS), either review the OS or look at the Wiki TOGETHER WITH here.

But, maybe someone will start a separate thread on "JAVA on Microsoft" discussion or maybe just "The Merits of JAVA in Puppy" discussion thread..

AngryIP, still today, beats the pants off every other LAN IP scanner I have run across (with the exception of hardware LAN scanners). In and of itself, it is small and very fast.

And, AngryIP continues to be maintained for the OS community. It could be very useful for those of us who have need to scan the LAN for various support reasons.

Hope this helps

Anyone know of a solution that does not require java? (I want to be able to see if any data packets are being sent to a printer of known IP)

The reason I'm looking at this sort of technology is that one of my customers has purchased our brand of printer and has asked me to replace it as they say "it has a broken network port".

However, they can ping it, and can access the printers internal web page, so basic network functionality is ok. I am able to communicate directly to the printer via crossover cable from my WinXP laptop, and can ping, access the internal webpage, and print through the network port without problems. The customer insists that there is nothing in their network or print subsystem which could cause print packets to be lost, but I suspect that their print spooler has marked the printer as offline somehow and is not issuing the print data. (customer is a large corporate customer with a distributed network citywide and will not confirm to me what server system they are using but I suspect some form of Citrix /server 2003 combo).

I initially asked them to set up a new IP address and print queue as I suspected the original queue has got itself tied in a knot somehow (I've often seen such things before) but they seem unwilling to do this.

I have also asked if there is any way they could look at the router logs to see if packets were being ignored/dumped (or at least counted maybe - so we could get a feeling for how much data was attempting to get through) but they scoffed at the idea and told me to bring a new printer. (That is an option of course but wouldn't prove much because it would have a different MAC address, and they would set it up with a different IP and print queue anyway, so I would expect that to work, but it's not that helpful in terms of identifying why this is happening)

I was hopeful that I could "hook into" the cable going to the printer and identify what type of packets are being sent to the printers IP address, and see if the printer was simply ignoring them. I realise I need to use a lot of caution on the customers netwrok (and would not use this method without their permission...) but I would like to prove that I can make the technology work at home before attempting to use it at work.

I can start a thread for this if you think that would be better...
