Layer 3 network and netboot/multicasting - will/can it work across subnets?
Hi, have been running netboot across a few subnets using multiple nics and vlans that worked fine.
We're to move to layer 3 so the vlans are going.
So my problem is getting it to run across the subnets. Is there something we need to do to the network to allow me to it see the netboot images and can I run things as before, or as I suspect do I need to move to multicasting?
Apologies if my question is a bit vague. Not 100% sure what the network change will do to the netboot system and how to adapt to it. thanks, Patrick

Multiple routers and subnets - can't access across subnets
Hey all, I'm having an issue with multiple routers and subnets on my FIOS connection. Here's how everything is setup:
Primary router:
ActionTec MI424WR Rev D (from Verizon)
WAN IP: From ISP
WAN NETMASK: From ISP
LAN IP: 192.168.1.1LAN NETMASK: 255.255.255.0
Secondary router (WAN connected to ActionTec LAN):
Belkin N750 gigabit w/ 802.11n
WAN IP: 192.168.1.2
WAN NETMASK: 255.255.255.0
LAN IP: 192.168.2.1
LAN NETMASK: 255.255.255.0
With this setup, I have the secondary router's WAN port connected to a LAN port on the primary router. Each are broadcasting an SSID and each are running DHCP to assign address to their respective subnets. Everything was well and good, except that I could reach 192.168.1.* systems from 192.168.2.*, but not vice versa -- anything connected to the Primary router was blind to systems connected to Secondary. Also, I could not ping anything on .2 from .1.
So, I added the following static route to the primary router:
DESTINATION: 192.168.2.0
NETMASK: 255.255.255.0
GATEWAY: 192.168.1.2
Once this was added to the router, I could ping everything, so that was good. However, even though .1 can now ping .2, I can't access certain things such as the web interface of my NAS (192.168.2.2). I can ping it, but accessing it in the browser from .1 doesn't work; however, accessing from .2 does work.
I think the ActionTec router might be blocking it, but that's just a guess. The firewall on this thing has me thoroughly confused. Currently, I have 192.168.1.2 in the DMZ on the ActionTec, but that didn't make a difference. I've also completely disabled the firewall on the secondary Belkin router, but still nothing.
Any help from the pros here? Much appreciated!
Solved!
Go to Solution.Ok, I figured it out and everything is now working. The issue appears to be that the ActionTec router doesn't recognize traffic from Subnet 1 to Subnet 2 as internal traffic -- it treats it as external traffic and closes it off. To fix this, it required some Advanced Firewall Filters that were far from unituitive and took a lot of testing to get it just right. If anyone runs into a similar situation in the future, here's a rundown of what I did to make it all work:
Primary Router:
ActionTec, MI424WR Rev D
WAN IP/NETMASK:Assigned by ISP
LAN IP/NETMASK:192.168.1.1 / 255.255.255.0
Secondary Router:
Belkin N750 Gigabit w/ 802.11n
WAN IP/NETMASK:192.168.1.2 / 255.255.255.0
LAN IP/NETMASK:192.168.2.1 / 255.255.255.0
Plug Secondary router's WAN port into a LAN port on the Primary router.
Setup Secondary router to have static LAN address (192.168.1.2)
At this point, you should have 2 separate subnets: Subnet 1 (192.168.1.*) and Subnet 2 (192.168.2.*).
Systems on both subnets should be able to reach the internet. Also, Subnet 2 should be able to ping and reach systems on Subnet 1; however, systems on Subnet 1 should not be able to ping or reach systems on Subnet 2. For this, we need to create a static route so Subnet 1 can reach Subnet 2.
Create and apply the following static route in the Primary router: (Advanced > Routing)
RULE NAME:Network (Home/Office)
DESTINATION:192.168.2.0(your secondary subnet)
GATEWAY:192.168.1.2(secondary router's WAN IP)
NETMASK:255.255.255.0
METRIC:1
The router now has a route between Subnet 1 (192.168.1.*) and Subnet 2 (192.168.2.*). You should be able to ping systems on Subnet 1 from 2, and ping systems on Subnet 2 from 1. You should not be able to access any systems, though -- the firewall is still blocking all but ping traffic from Subnet 1 to Subnet 2. We need to create some firewall rules to allow this communication.
Make sure Primary firewall is set to at least typical/medium (Firewall Settings > General).
We need to create some network objects to make it easier to manage the rules we'll create. Go to Advanced > Network Objects and do the following:
1.Click Add. You are now on Edit Network Object screen.
2.Set Description to 'Subnet 1'.
3.In Items section below, click Add.
4.Set Network Object Type to 'IP Subnet'.
5.Set Subnet IP Address to 192.168.1.0.
6.Set Subnet Mask to 255.255.255.0.
7.Click Apply. You are now back on Edit Network Object screen.
8.Click Apply. You are now back on Network Objects Screen.
9.Repeat the above steps again, but this time creating a second network object called 'Subnet 2':
Nameubnet 2
IP Subnet:192.168.2.0
Subnet Mask:255.255.255.0
Now we create the firewall rules. Go to Firewall Settings > Advanced Filtering.
In the Inbound/Input rules section, click the Add link next to Network (Home/Office) Rules.
Create the following Advanced Filter:
SOURCE ADDRESSelect 'Subnet 1'
DEST. ADDRESSelect 'Subnet 2'
PROTOCOL:'Any'
OPERATION:'Accept Packet'
OCCUR:'Always'
Click Apply. You will now be back on the Advanced Filtering page.
In the Outbound rules section, click the Add link next to Network (Home/Office) Rules.
Create the following Advanced Filter:
SOURCE ADDRESSelect 'Subnet 1'
DEST. ADDRESSelect 'Subnet 2'
PROTOCOL:'Any'
OPERATION:'Accept Packet'
OCCUR:'Always'
Click Apply. You will now be back on the Advanced Filtering page.
Click Apply.
You're all done. You should now have internet access on both subnets, be able to ping across subnets and also be able to access services across subnets (local webservers, SSH, telnet, mail, etc). You will not be able to see network file shares across subnets in Windows, however, as this requires a WINS server (which is well outside the scope of this post). For instance, I have a Western Digital NAS on the 192.168.2.0 subnet that I can access as \\Mybooklive\ from within Subnet 2; on Subnet 1, however, I have to access it by its IP \\192.168.2.10\. -
I brought a iPhone (A1429) unlocked, sent it as a gift to my mate in Arizona, she is on the Verizon Network which in CDMA Will this phone work for her or have I just wasted $900 :/ I have done all the research and to me it looks like it should work.
Can anyone give me a difintive answer please.Yes but I have brought the A1429 where as the information you provided states that it's the A1428.
The unlocked iPhone 5 is model A1428. For details on LTE support see www.apple.com/iphone/LTE. The unlocked iPhone will not work with CDMA carriers such as Verizon Wireless or Sprint. Learn more about the unlocked iPhone
And Apple websight also states that the A1429 is both CDMA and GSM here: http://support.apple.com/kb/HT3939#iPhone5 -
macbook pro 15" mid 2010 i spilled water on keyboard now it wont power on if the battery is connected and the keys on keyboard doesnt work it works fine with no battery and external keyboard if i order a battery and new keyboard will every else work again lik it did before
If you have records that show that you've taken your MacBook Pro in for a year to fix the machine, I would escalate the problem to Apple Customer Relations - unfortunately I don't have a number for Spain.
It would only seem logical to me that if you've been trying to have the machine repaired during the time that the 'recall' was in effect that you should be eligible for a new logic board. But only customer relations will be able to make that call.
Good luck - take the issue as high up the food chain as you can and see what happens.

I have an older Hitachi widescreen 1080p TV that has a DVI input, no HDMI input. Is there an adapter and if so will it still work?
As HDMI is the only supported method there will no guarantee with any converter.
DVI doesn't tranfer audio so you would have to either go through optical to connect speakers, or use a DAC in connection with analogue speakers.
Also, unless the TV is HDCP compliant you will be unable to play protected content (ie iTunes, Netflix) -
My iMac doesnt' see my Canon MP560 wi fi scanner ever since I created a wireless network in my house. Can't find a way to change whatever settings i need to to connect the scanner. help.
Well let's see if we can help you get set up. Have you got any 2.4 GHz cordless phones in the house and if so try unplugging them and do a hard reset of the express.
1. unplug the express
2. press the reset button
3. while pressing the reset button plug in the base station
4. keep holding the rest button till you see 4 green lights flash
you may have to hold it for 30 seconds or so
if this doesn't work try plugging the express in right beside the computer and then going through the airport setup assistant
Good luck
Let me know

Can not get Netboot working across subnets
On the same subnet all my images work correctly, but once I try to netboot form a different subnet it doesn't work anymore. I am correctly using the bless command, and I have tried both specifying the server (to get the default image) and specifying the booter file (to get the specific image). If I just use the --server option the log shows BSDP inform and BSDP ACK[LIST] but nothing after that... there is no select. Again, on the same subnet it will use select and work normally. If I use the --booter option then sometimes I can get the netboot to start but I get an error (for example, AST says there was a network error and NetInstalls do not start).
I do know that this used to work, and in the process of changing computers and upgrading to Lion server it stopped working. Any ideas?Depending on your network configuration it maybe that the simplest option is to multi-home your NetBoot server so it is visible on each subnet. Multiple servers is of course another option.
However have a look at the information on the following links and see if any of it helps.

Will UE-V work across Physical and virtual desktops
We are currently evaluating few product, and are looking for a product that can work across our VMWare VDI infrastructure as well as physical hardware to provide transparent and seamless UEM. Profile management is a key for us, the goal is to achieve as
identical as possible experience between out Windows 7 and 8 machines.UE-V is designed to synchronize data between any desired environments. This includes physical systems, virtual desktops, RemoteApp applications, and App-V applications.
See the Comparing UE-V to other Microsoft products section here.
The ability to synchronize common settings between Windows 7 and Windows 8 was
added in UE-V Beta 2.

All- I get this message ("iPhone can not make or receive calls. Restore from iTunes" (happend once while on airplain mode and now once while in wifi only area, out of cell range)). iPhone 4. Newest OS. Never happened with old OS! Cycling phone on/off does not help. Ignoring message causes phone to cycle off then on. After first time this happened, I restored. Six days later...same problem! Clearly a new fix is necessary. Suggestions?
I have not tried that...I will look up the process so that I can do it correctly (and still transfer all of my files, contacts, etc). Any suggestions? What is the advantage of restoring as a new device..is this more akin to a complete wipe of a hard drive?

HP Officejet Pro 8600 N911a

Cannot connect to the server.
Check the Internet connection and try again. Or contact your system administrator or the person who set up the printer.
If your network requires a proxy server address to connect to Internet, click Enter Proxy or check your browser settings.
The printer is connected to the network with proper DNS I am the adminastratorThe steps below typically resolve the issue you’re experiencing:
1. Unplug the power cord from the back of the printer.
2. Unplug the power cord from the back of your router (and modem, if separate from the router).
3. Wait 20 seconds, then plug the router (and modem, if applicable) back in.
4. Wait 30 seconds, then plug the printer back in and power it on.
5. Press the ePrint button on the printer's front panel, and it should try to connect to Web Services again.
Those steps usually resolve the issue, but if it still occurs you can try setting static network info for the printer (which sometimes helps to stabilize the printer's ability to get outside of your network, to the internet):
1. Press the network icon at the top of the printer's screen and note the IP address.
2. Enter the IP address into the address bar of a web browser on a computer and press enter or click the browser's go button.
3. The printer status page should be opened. Click on Network at the top.
4. Select Proxy Settings.
Note: If you are prompted for a redirect, select OK. If you receive a certificate warning, select the option that lets you continue anyway.
If you receive a Internal System Error, refresh the page until it loads the proxy settings.
5. Verify that all fields are blank. If they are not, clear them and make sure the Proxy Server requires authentication is unchecked and click apply. You should get a success message.
6. Click on IPv4 under the correct connection (wired or wireless) on the left.
Note: If you only see IP Address Configuration and DNS Address Configuration with a yellow note, refresh the page until it loads completely.
8. Leave the IP Address Configuration as Automatic IP.
9. Change DNS Address Configuration to Manual DNS server.
10. Enter 8.8.8.8 for the Manual Preferred DNS Server and 8.8.4.4 for the Manual Alternate DNS Server.
11. Click Apply and you should get a success message.
12. Power off the printer for 30 seconds and then turn it back on to force the new settings to take effect.

Finder freezes and Networking and Locked drives will not unlock
I have been having trouble with my Mini'S finder freezing when I try to connect to another computer. Sometimes it works OK but it often freezes, beachball and cannot relaunch finder, have to reboot. The mini is Intel Duo, Network is 6 windows machines and 1 g5 PPC 1.8 single. An Apple Airport Extreme, a Linksys router and a Buffalo router, I can connect to the Win machines no problem but , like I said, often when connecting to the G5 I get the Finder Crash, but only about 60 % of the time. I have sharing turned on, Personal and Windows on both machines. I am admin on both. Also the MINI drops Network connections which have been working for a few hours.
I am beginning to think the MINI's Network card is bad.
ANother maybe related issue, from the MINI, 2 drives on the G5 appear as Locked, I have repeatedly unlocked them with Xray and by the terminal, from the G5 (to which the drives are attached) the drives show unlocked but always from the mini they appear as locked. I have tried to unlock them form the MINIS terminal but get a long Beach Ball.
Both the G5 and Mini are running the latest OSX and everything else is updated.
Anyone else relate to these issues? thank you,
