To get DNS, Local IP, Subnet Mask are...

I need to be able to figure out what the local DNS, IP and subnet mask are... I am not running an applet, this is a full blown java program... I know this and similar questions have been asked tons of times but are they any way of doing this across multiple platforms... I know you can do it by calling a runtime(), then doing IPConfig /ALL and pulling the info out of there...
Any alternatives?
Thanks
Jeremy

You can get the host name and IP address pretty easily using InetAddress.
InetAddress localHost = InetAddress.getLocalHost();
String name = localHost.getHostName();
String ip = localHost.getHostAddress();

HT1218 I'm trying to set up a new iPad..it asks for my WiFi network.. I find the network..then it asks for information that I have no idea about: IP address, Subnet Mask, Routet, DNS, Search Domains, Client ID..also the headings are: DHCP,BootP, Static..c

I am trying to set up my new iPad. it asks for a WiFi connection.. I have one..then the next page asks for these things:DHCP,BootP,Ststic then IP address, Subnet Mask, Router, DNS, Search Domain, Client ID then HTTP Proxy I have no idea what any of this means...can someone please help me???

Thank you sooo much. I was so disappointed...I couldn't wait to get started with the new iPad..then ran into the problem. So simple. You made my day. Thank you for your expertise!!

How to get WSID & Subnet Mask for local system

Hi,
In my application I have to show local system IP Address, WSID & Subnet Mask.
Local IP Address I can obtain using InetAddress.getLocalHost() but couldnt get any idea how
to get WSID & Subnet Mask.
Please help me out.
Thanks in advance.

Thanks for your reply,
Actually my application is using JDK 1.5 & I cannot change the JDK version because application is working on various client location.
Is there no option to get WSID or Subnet Mask in JDK 1.5. Need some alternative solution which will work in JDK 1.5

How do I get the subnet mask

How do I get the subnet mask for each IP address my host supports in Java? I need to get this so I can send a local broadcast on a specific subnet.
Thanks,
Doug Grover

Actually on windows you are probably going to beusing
ipconfig."ipconfig" will give you the values for each network
interface on your machine bound to the TCP/IP
protocol.
"route print" will print the windows routing table for
the network the machine is on.
Quoted from the Microsoft web site, "The routing table
is built automatically, based on the current TCP/IP
configuration of your computer. Each route occupies a
single line in the displayed table. The routing table
is searched by your computer for an entry that is the
most specific match to the destination IP address."
Yes I know what it does.
In most cases when someone wants this information they use ipconfig.
Although your suggestion does work on older boxes as well. But the result is somewhat less evident.

Assigning non-standard subnet mask to local IP address on WRT54GX

I need to configure my WRT54GX V1 as an access point. I know how to accomplish this, but our corporate network uses a subnet mask of 255.255.252.0 How can I assign this net mask? The only options are contained in a drop-down menu and what I need is not there. Is there a different way to assign the subnet mask rather than using the menues?

It is a known limitation of Linksys wireless routers that they only support LAN subnets up to 255.255.255.0. I guess the assumption was that the router only runs LANs for up to 253 LAN devices. The plain access point setup (i.e. uplink through LAN-LAN connection) was never properly considered an option although it is documented in the Linksys easy answers.
Anyway, to set up the WRT as access point the LAN IP address of the WRT and the subnet mask is not important for the wireless connectivity into the LAN. The LAN IP address and subnet mask is only relevant to access the web interface of the WRT to make configuration changes. You have to make sure that the DHCP server on the WRT is turned off and that a LAN port of the WRT is wired to your existing LAN.
For the LAN IP address setup you have three options:
1. Use an available IP address inside your LAN and use subnet mask 255.255.255.0, e.g. if your LAN uses 10.0.0.0/255.255.252.0, assign the WRT an IP address of 10.0.3.200 with subnet mask 255.255.255.0. Of course, in that case you are only able to access the web interface of the WRT http://10.0.3.200/ from a computer in 10.0.3.* because that's the IP subnet which the WRT thinks is connected to its LAN ports. You cannot use a computer with IP address 10.0.{0,1,2}.* because the WRT does not know how to route these IP addresses. If your computer has an IP address outside the configured WRT LAN subnet you must temporarily change the IP address of the computer.
2. If you assign a LAN IP address and subnet mask to your WRT which includes a network router you may be able to get full connectivity by setting up static routes in the WRT. For instance, if you assign 10.0.3.200/255.255.255.0 to your WRT and your main LAN router sits at 10.0.3.254/255.255.252.0 you may be able to set up static routes for destinations 10.0.0.0/255.255.254.0 and 10.0.2.0/255.255.255.0 (or if it works even simply destination 10.0.0.0/255.255.252.0) to gateway IP address 10.0.3.254 on the LAN interface. Traffic from the computer to the router should go directly while the responses from the router to the computer go through the main router. I think this should work although I am not 100% sure.
3. Use any IP address outside your LAN, e.g. the default 192.168.1.1/255.255.255.0. Again, you must temporarily set up a static IP address on your computer to gain access to the web interface. But even with a LAN IP address outside your LAN the WRT will still bridge wireless clients into the LAN as it is supposed to do.

My wifi network connection is not working, will read "unable to join". Am able to access as a guest. When I hit the blue arrow on the right hand side of my network there is no information e.g ip address, subnet mask, etc. This info is in my guest area.

My network has not been working today. When I click on it it says "unable to access nhe network". My guest network will work. When I hit the blue arrow on the right hand side of my network there is no information in the IP address, subnet mask, router, etc. There is information in my guest section when I checked. I have unplugged and replugged my router and turned my Wifi button of and off, started and restarted my Ipod as per internet suggestions. Would anyone know how to get my network reactivated. I am nervous to hit reset network settings in case I lose all my music and icons, etc. added since I got my Ipod. Thank you for any assistance

Do other devices now connect?
Did the iPod connect before?
What encryption/security is the router using?
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router

Loading external SWF with masked content - get size of masked area

I am loading an external swf using the SWFLoader component. The swf that is being loaded is masked so that only a portion is being shown. However, when it's loaded the actual size of the swf (loader.content.width && loader.content.height) is the complete swf including the masked area. Therefore, the loaded swf does not display properly in the itemrenderer Is there a way to to grab the size of the just the masked area as opposed to getting the size of the entire swf's contents (area not masked)?
One item to note that is complicating the issue, is that these are swf files that have already been created and there are many of them. In some instances, the size of the stage matches up with the size of the masked area. In other instances, the stage is larger (or possibly smaller) than the masked area movieclip as well as possibly the actual size of the movieclip (w/o the mask).
I am currently loading the external swf in using a Loader. Once loaded, I make a copy (screen shot) of the swf by creating a bmp of the loader.content.This is done as I don't want to have any animations being shown on screen at this moment. I am setting the size of the bmp using using loader.content.width & loader.content.height. I then set the SWFLoader.source to the bitmap.

Here's the code I am using to load the swf:
     <fx:Script>
            <![CDATA[
        protected function application1_applicationCompleteHandler(event:FlexEvent):void {
             loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onSWFLoaded);
             loader.load(new URLRequest("c:\\Flex Testing\\FA warns Mr. Jones.swf"), context);
        private function onSWFLoaded(event:Event):void {
            bmData=new BitmapData(loader.content.width, loader.content.height, true, 0x990000);
             bmData.draw(loader.content, new Matrix());
            bmp=new Bitmap(bmData);
            swfLoader.source=bmp;
             addElement(swfLoader);
            with (swfLoader)
                setStyle('verticalAlign', "middle");
                 setStyle('horizontalAlign', 'center');
                 verticalCenter=0;
                horizontalCenter=0
                 scaleContent=true;
                maintainAspectRatio=true;

                 width=200;
                height=200;

Subnet mask 255.255.255.255 assigned to VPN client - can't ping LAN

Hi,
I configured PIX 501 with PPTP VPN to connect to the small office (PIX FW, Win 2000 Server, several Win clients, LAN IP 10.0.0.X/24):
ip local pool mypool 10.0.0.101-10.0.0.105
vpdn group mygroup accept dialin pptp
vpdn group mygroup ppp authentication mschap
vpdn group mygroup ppp encryption mppe 128 required
vpdn group mygroup client configuration address local mypool
vpdn group mygroup client configuration dns 10.0.0.15
vpdn group mygroup pptp echo 60
vpdn group mygroup client authentication local
vpdn username xxxx password *********
vpdn enable outside
I can connect to the office using Win VPN client, but I can't ping any hosts in the office network. I suspect that the reason for that is subnet mask assigned to the VPN client: 255.255.255.255. ipconfig of the VPN client:
PPP adapter Office:
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 10.0.0.101
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . :
Default GW is missing too, but I think this is not the main problem.
Any way, what is wrong with my config? How to fix subnet mask assigned to clients? Or may be my assumption is wrong and this mask is ok? What is wrong then?
Any input will be greatly appreciated!
George

There are remnants of old config, I just recently took over this network, some lines look odd to me, but I did not touch what works. VPN config is all mine.
PIX internal 10.0.0.23 - is a gateway for the network. DNS server in LAN - 10.0.0.15.
I've been reading about the problem and came across several posts that this subnet mask is normal, but it puzzles me - how can this host communicate with anyone else if there is no room for other hosts in this network (according to the mask)?!
Thanks again!

Virtual Switch adapter getting link-local IP address (apipa)

Hi Everyone,
Not sure what I am doing wrong here.
I have installed an Hyper-V 2012 R2 core server on a brand new Dell server.
I then went to use Virtual Switch Manager via Hyper-V Manager to create a virtual switch adapter, selected external (I want to share my existing server NIC), allow management operating system to share this network adapter.
Then I configured my virtual machine to use this.
When I start the virtual machine I get a 169 type IP address, cannot ping gateway or host. The VM does not even get a proper IP using DHCP. DHCP is working fine from another physical server.
When I check the hyperv core host and select 8 for "Network Settings", I get:
15 192.168.20.44 Broadcom NetXtreme Gigabit Ethernet #5
22 169.254.101.167 Hyper-V Virtual Ethernet Adapter #2
Why is hyperv creating a virtual adapter with an Apipa address which is not usable?
I followed all the steps correctly, but it does not work.
Can anyone point me into the right direction to solve this problem?
Thanks and regards

Leopard wifi issue: subnet mask?

I have the common Leopard wifi problem:
4 computers, all linked to new Airport Extreme with 10.4
3 of 4 link with Leopard.
Have tried all suggestions to fix the problem with the IMac G5 that won't link.
Always says that the iMac has self-assigned IP and can not connect
Noted that when the problematic machine does rarely link, Subnet Mask is 255.255.255.0
Same with all linking machines.
When doesn't link, subnet mask is 255.255.0.0.
Does this give any hint as to the problem.

This might not be related, but you could try changing the DNS settings in your Router to use OpenDNS instead of the number automatically set by your ISP. You just need to manually enter the 2 numbers:
208.67.222.222
208.67.220.220
There are good instructions on the OpenDNS website. It's worth trying just to see if it solves your problem:

Defining VPN Subnet Mask?

Howdy,
Ok this problem occurs on Windows Vista, and is, to my knowledge classed as a bug, as it never occured on XP. So when I migrated over to OS X I assumed it would not be there... I was wrong, cos it is!
I connect to several VPNs to access MySQL DB's, and I use these everyday and are very important. Now a few of the VPN's use a subnet mask of 255.255.255.0, like most connections. Now the other VPNs use a subnet mask of 255.255.240.0, and when connecting to these VPN's OS X just assumes the subnet is 255.255.255.0 and therefore, even though it connects fine, I cannot access anything on this server cos of this problem!
Now the only way, to my knowledge, around this is to run the ifconfig command to get my assigned IP Address, then run the command:
sudo route add -net 192.168.16.0 192.168.16.* 255.255.240.0
Where * represents the last 1/2 digits of my assigned IP address. This does work, but is quite frustrating, just as it was running the "route" command on Vista.
Does anyone know of a way around this? So I can tell OS X to add me a subnet mask of 255.255.240.0? Or even a way in OS X to automatically run the above command via terminal when I connect?
Any help will be appreciated!

Do you know how I can join my office domain via the PPTP connection? I've triend both the QuickVPN client as well as, Windows built-in VPN connection. I've only been able to successfully connect using Windows VPN connection. I could not get QuickVPN client to work.

How to configure the eth1 port of NIcRIO 9024 to another IP address and subnet mask

Hi ,
I am using cRIO 9024 and am planning to configure it to be an MMS server that interacts with a client which is in another network with different IP and subnetmask. I want to run the server VIs from the host computer via the eth0 port and want to communicate the MMS messages through the eth1 port. the eth0 port is configured as a static IP as shown in the screenshot attached and would like to assign a separate IP and subnet mask to the other port . But when I try to save the configuration I get the error "Could not save your changes tot he target.The subnet mask for eth1 is invalid" .
I have already directly cross connected the Crio and have disabled the firewalls and still am not able to configure it.
1) is it possible to configure the ethernet ports to have separate IPs corresponding to different networks and thus the subnet masks?
2) If its possible then what is the mistake i am doing while configuring it ?
I would be extremaly grateful to have a reply on this as its pretty desperate to spend a lot of time just to set up the IP configurations..!!!!!
Regards
Abhinav

Dear Abhinav,
I'm sorry but what you are tryining to do is not suported by the Second Ethrnet Port on any cRIO and so you getting this error meeage.
Here a abstract out ouf the KnowledgeBase How do I Configure the Dual Ethernet Ports on Real-Time Controllers?:
Ethernet port 2 is currently not supported to communicate outside its own subnet. There is no capability of configuring the Default Gateway for Ethernet port 2 and therefore cannot connect to a large isolated intranet. However, there appears to be a common misconception that this port can only be used for communication between NI products: this is not the case, though any communication through the secondary port must be within the same subnet.

Ip address & subnet mask !

I have recently encountered a problem with my system and the assigned IP Address and was not sure why. I have a wireless connection on the iMac with it setup to get the IP address automatically but the system gets the wrong subnet mask every time. It gets (255.255.0.0) the correct subnext mask in the other mac's is (255.255.255.0). Where is it getting the inappropriate address and why does it didn't assign the correct one!!

Are you sure that both these macs are getting IP addresses from the same place? (1 wired, 1 wireless...might mean that mac2 is getting neighbor's wifi)
Are you certain that this trouble mac is configured to be fully Automatic in the NetworkSystemPreferences?
"Conigure IPv4...Using DHCP" ( not manually, not dhcp with manual address, not bootP...)
Have you done a cold start to all your network devices (macs, router, modem, network printers?)
Power-cycle them off. Count 2 minutes. Start up modem, pause. Start up router/BaseStation, pause. Start up mac(s).
You haven't said what kind of router/baseStation you've got. 'Twould help, maybe.
added: Do you have a wireless modem/router AND a wireless airportBS/router/something)?
