Rc.conf with complex networks

I have just added wireless access to my home network server, and it works great. I already had a wired network, so I have used a bridge to bring them together. Now the wireless network and the wired network provide an internet gateway through dnsmasq. Here is a diagram:
ethernet:eth0
} bridge:[email protected] --> dnsmasq --> internet:eth1@DHCP
wireless:ath0
The only problem I now face is how I can set this up in my bootscripts. I have a crude solution of my own, but I was wondering if there was some way I can make it more safe, clean and easy with rc.conf. Look at this guide as an example of how easy this can be set up in Debian-based distros.
Eventually I want to write a wiki guide about how to set up an Arch Linux machine as a wireless AP, so it would be really great to get a perfect, complete solution for this.

Have a look at /etc/conf.d/bridges and the related code in /etc/rc.d/network. I haven't used it myself, but it seems to be all there. If not, feel free to submit patches.

[SOLVED] Qemu with host networking space.

Hello, I'm trying to lunch Qemu with host networking, so the VM's can talk to each other, what I did so far is creating the following bridges ( Actually virt-manager did that for me ):
br0, virbr0 -> virbr0-nic ( the interface )
and have the following network interfaces:
br0, lo, virbr0, wlp1s0
What I think I'm missing is something on the code... I'm lunching with:
qemu-system-x86 -kernel kernel -cpu host -m 2024 -hda image.image
I did review the following manuals
https://wiki.archlinux.org/index.php/QE … networking
https://wiki.archlinux.org/index.php/Network_bridge
I'm missing the right command, thanks.

Sorry if I am late to the party... but here's how I do this with bridged networking.
Let's assume that I have 2 guests, an ArchLinux and Window 7. These are the start scripts:
: cat start-arch.sh
#!/bin/bash
vm_dir="/export/scratch/VMs"
scripts_dir="${vm_dir}/scripts"
. ${scripts_dir}/macaddr-gen.sh
# Generate a random MAC address
gen_macaddr mac
# Start the emulator
qemu-system-x86_64 -enable-kvm -smp 2 \
-net bridge,br=br0 -net nic,macaddr=${mac},model=virtio \
-drive file="${vm_dir}/arch-x86_64-1",if=virtio -nographic
: cat start-win7.sh
#!/bin/bash
vm_dir="/export/scratch/VMs"
scripts_dir="${vm_dir}/scripts"
. ${scripts_dir}/macaddr-gen.sh
# Generate a random MAC address
gen_macaddr mac
# Start the emulator
qemu-system-x86_64 -enable-kvm -m 3G -smp 2 \
-net bridge,br=br0 -net nic,macaddr=${mac},model=virtio \
-drive file="${vm_dir}/win7-x86_64-1",if=virtio \
-usbdevice tablet -vga qxl -spice port=5930,disable-ticketing
: cat macaddr-gen.sh
#!/bin/bash
# Generate a random MAC address
gen_macaddr() {
local str i macaddr _mac=$1
str=$(cat /dev/random | tr -cd '[:xdigit:]' | head -c 12 | \
tr '[:upper:]' '[:lower:]')
i=0
macaddr=""
while [ $i -lt 6 ]; do
macaddr=${macaddr}${str:0:2}":"
str=${str:2}
let i=i+1
done
eval $_mac=\${macaddr%:}
: cat /etc/qemu/bridge.conf
allow br0
Note, that the MAC addresses of virtualized NICs in the VMs must be different. If you now do
: ./start-arch.sh &
: ./start-win7.sh
Assuming that you have already set up a bridge br0, qemu will create several tap? interfaces and insert them into that bridge (using the qemu-bridge-helper suid binary), and you'll have a virtual LAN rooted at br0.
EDIT: Added a slightly faster random MAC generator and comments.

Having trouble converting array to spreadsheet string, storing the file and coverting back to array with complex numbers

I am working with a network analyzer. I have arrays made of 5 columns the first consisting of an integer and the next four consisting of complex numbers. I am converting the array into a spreadsheet string and then saving the file using the write characters to a file VI. That seems to work well as when I open the file in Excel all the data is there. However when I try to reverse the process, open file and convert back to array, I loose some of the data. Specifically the imaginary parts of my complex numbers are all going to zero. I have narrowed down the problem to be in the conversion from spreadsheet string to array and vice versa. I
think the problem may be with the 'format' input to the VI. I do not have an adequate resource for this so I am not sure what to put in to accomplish my task. Any takers?

Hi Biz
I don't think there is a direct way of converting a complex number to a
string, so when you convert the array to a spreadsheet string, the
numbers would be converted to real data.
However, you could try separating the real and imaginary parts using the
"Numeric: Complex to Re/Im" function, and then store these - either in
separate files or in adjacent columns/rows in the same file. Then, when
you read in the data again, use the "Numeric: Re/Im to Complex" function
to put the two "halves" together.
If you actually want Excel to interpret the numbers as imaginary, then
you'll probably want to create a string for each complex number of the
form "Re + Im*i" (after separating the Re and Im parts), by using
"String:Format into String" with 2 numeric inputs and the format string
"%f+%fi".
Reading the data back into Labview then would require splitting the
string into the 2 pieces by using "Stringcan from String" with 2
numeric outputs (smae precision as original numbers specified by the 2
Default Value inputs) and the same format string "%f+%fi", and then using
the above-mentioned "Numeric: Re/Im to Complex" function. It worked for
me, so if you can't follow what I am describing, send me an email and I
can email you what I did (LV 5.1.1).

How to enable resource sharing with complex AEBS setup

I have a complex AEBS + Netgear network configuration that I am trying to enable resource sharing on. The Netgear router is necessary because it provides excellent per-user parental controls and content filtering that the AEBS lacks. The setup is operational (network connectivity works as expected), but I cannot figure out how to enable cross-network resource visibility and sharing.
Here is the network configuration:
|Vz Fios PPoEE |
|
v
|___
|AEBS|
| __Mac Mini (wireless)
| __AppleTV (wireless)
| __Wii (wireless)
| __MBPC2Duo (wireless)
| __WinXp PC1 (wired)
|
v
|______
|Netgear|
| __WinXP PC2/Printer (wired)
| __WinXp PC3 (wired)
| __iBook (wireless)
| __Vista Laptop1 (wireless)
| __Vista Laptop2 (wireless)
The Mini, AppleTV, Wii and MBPC2Duo all connect wirelessly with the AEBS. The Netgear router is wired to the AEBS. This in turn has 2 wired clients and three wireless clients as illustrated.
The Netgear router receives an IP address assignment from the AEBS (in the 10.0.1.x range) via DHCP and in turn assigns IP addresses (in the 192.168.1.x range) to attached clients via DHCP
The setup is operational and operates flawlessly --network-wise. However, I now need to enable resource sharing as follows:
1) Setup the Mini as the media hub, configured to allow:
a. storage of all iTunes, iPhoto, iMovie and garage band content to an attached external hard drive,
b. sharing of content on the Mini with iTunes on each computer (Macs and Pcs) and the AppleTV
2) Share the printer attached to Windows XP PC2 with all computers (Macs and PCs)
Questions:
1. Is this possible with this network configuration?
2. If so, how would I configure the relevant elements?
3. Is it better to attach the external media storage to the AEBS vs attaching it to the Mini?
Thanks!

Thanks Tesserax. After some digging I was able to find bridge mode config instructions for the Netgear router.
Follow-up question:
Given my desire to centralize media access via the Mac Mini, what is the best way to set up my media storage device (320G HD)?
I see the following options:
A. NAS device via USB 2.0 connection to the AEBS, or
B. Supplemental hard drive on the Mac Mini via USB 2.0 or Firewire.
Thoughts/suggestions?
Thanks!

My apps store will not go online with verizon network, but on wifi it works. I am on an iphone 4, verizon. I tried to do a complete, backup and restore on the phone 1 day before i noticed this problem, The backup finished but the RESTORE would fail I had an error, could not access Apple server ( some server name I cant remember).
I have plenty of space available on the iphone,
8gb free,
ios version- 6.1.3 ( 10B329)
carrier - Verizon 14.0
Modem Firmware - 3.0.04
Can someone help.
I tried doing my backup restore on the same computer as I once did a year ago. and THis time I cant do the restore on the iphone.
computer osx is 10.5.8
itunes version 10.
I do not wish to go to ios 7 at this time.

Basic troubleshooting is reset, restart, restore (first from backup then as new). Try each of these in order until the issue is resolved.
If the issue continues, contact the carrier to troubleshoot the network connectivity issues.

ASA 5505 Site-to-Site VPN with multiple networks

Hi,
I have 2 Cisco ASAs 5505 in the different places with a created connection Site-to-Site VPN. It’s working fine in the networks where they are (10.1.1.0/24 and 10.2.1.0/24 respectively).
Additionally to the ASA1 are connected two subnets: 10.1.2.0/24 and 10.1.3.0/24 and the ASA2 is connected to one subnet: 10.2.2.0/24
A problem is when I’m trying to get to a host in the subnet behind the ASA2 from the subnet behind the ASA1 and vice versa.
Any help would be greatly appreciated.

It's all about the crypto ACL. You have to combine all networks behind ASA1 with all networks behind ASA2. You can use object-groups for that to handle it. What's the config of your crypto ACL?

I am trying to connect to my Wifi Network. It is a Galaxy Nexus. I am trying to connect to this Hotspot. I have an iMac that works fine with my network but for some reason with this computer I cannot connect.

So far I have pulled the system configuration file, I have reset safari, I deleted all old passwords from the wifi network in Keychain I restarted both devices. I am at the end here and I cannot get it to work I have an iMac that works fine with my network but for some reason this computer will not connect. It is system wide specifically to my personal hotspot. I can connect fine to any other network (wifi) but just not mine. I have not changed any wifi settings. I have been trying to figure this out. I have a MacBook Pro Late 2006 model running Lion (10.7.5) So any ideas anyone? Please help!

12. At a WiFi hotspot, you can't get connected. The most frequent reason is the login screen for the WiFi hotspot is only able to be connected with a single type of browser. If Safari doesn't work, try Firefox, Chrome, Omniweb, or Opera.

Time Machine and "might be a problem with your network"

Hi! My Power Mac is from 2008, and I'm in the middle of replacing my hard drive. Here's a summary of what I've gone through, including various trouble shooting...
OK, the hard drive dies (all of which I wrote about in an earlier thread and, I think, not very relevant for this thread). While waiting to buy my replacement, I created an external bootable drive, hooked up via FW800. I created a new User Account, and then I used the Migration Assistant to bring in all the user settings, files, etc, from my Time Machine. It took many hours and and during the stage when it was transferring files, it gave me the prompt: "There might be a problem with your network. The other Mac is not responding. Make sure that all of your network devices are connected and turned on. Also, make sure that your Ethernet cables are still connected properly to your computer and to the network, or if using AirPort, that the base station is in range and turned on." After clicking "Continue" got me nowhere, I clicked Cancel, and it was a very incomplete migration [no apps, no files]. I didn't sweat this since this external drive is a temporary solution anyway.
Tonight I came home with the new internal drive, installed it, installed Leopard, and began the Setup Assistant. I got the same prompt as last night. NOTE: This time with Setup Assistant; last night was with Migration Assistant.
I notice from reviewing the boards that this Time Machine glitch seemed to happen a few years ago, in Leopard, and maybe hasn't happened since. But I haven't read a thread with a solution. (Maybe I missed it?)
A few things come to mind:
1. Could there be an issue with the fact that the computer is only 10.5 and many of the files/apps may have been installed when I was running 10.5.8? I'm just tossing that out there. For instance, what if I set up an initial User account, then updated the software to 10.5 and THEN used Migration Assistant to bring in the older account?
2. Soon, since I'm reinstalling Leopard, I'll get the prompt to use Setup Assistant, and this time I'll just select account settings and apps. I'll bring in the files manually, later. Since the progress window seems to get hung up during the file-transferring stage, maybe I'll have better luck if I skip that.
If anyone has any suggestions, man, I'd be way grateful!
Thanks!

"try trashing the timemachine.plist in your original user's Library>Preferences."
I didn't even get to that step. Here's what happened.
I went back to my original Admin account (the one I restored via Setup Assistant, from my Time Machine backup), and ran Migration Assistant again. I selected Applications only and when it gave me a prompt about the account name already existing. So, I created a new account name (TEMP 1, I called it).
All of my applications were restored.
Next, I tried it with all the files and folders. It didn't give me the duplicate name prompt this time. It copied all my flles and folders over.
Was it perfect? Well, a lot of the apps need some fresh registration and some upgrading, but I suppose that's to be expected. Or is it?
While I feel like this problem is in my rear-view mirror, I'm still interested in your suggestons for a Time Machine altenative.
Thanks again for your advice!

Anyone else had issues with phone network being unavailable on iPhone 4 since updating to iOS 5.0.1? My iPhone 4 is continually searching for a network and does not find my provider. I swapped SIMs with another iPhone 4 on ios 4 to confirm device problem.

Has anyone else had issues with phone network being unavailable on iPhone 4 since updating to iOS 5.0.1? My iPhone 4 is continually searching for a network and does not find AT&T, my provider. I swapped SIM cards with another iPhone 4 running ios 4 and established this is a device problem, not a SIM card problem.

Does the device get any signal?
Sounds like the device may have had a hardware failure. If it is out of warranty, the only option is the Out of Warranty replacement.
AppleCare is only an option if it is still under the original warranty.

Migrate Roles failes when migrating VMs with legacy network adapters (2008R2 - 2012)

I'm working on a upgrade of Hyper-V 2008R2 cluster to Hyper-V 2012 cluster. I am using the "migrate roles" feature of failover clustering to migrate the CSV's and VM's. The wizard ask to which switch the VMs need to be connected on the target cluster.
All VMs with network adapters can be started in the new cluster without any issues. If you look at the XML file of the migrated VMs with normal network adapters, a new XML has been generated in the proper 2012 format. However, all VM's with a legacy
network adapter fail to start. Also there is no migrated XML file in the VM directory. It is impossible to check or adjust the settings of the migrated VMs with legacy network adapters using the failover clustering console.
I have reproduced the issue in my lab several times, and it seems like a bug.
There are several workarounds, but I am looking for a real solution.

Hi,
We recommend that you use the legacy network adapter only to perform a network-based installation or when the guest operating system does not support the network adapter.
If the virtual machine continues to use the legacy network adapter it will not be able to leverage many of the features available in the Hyper-V virtual switch. You may want
to replace the legacy network adapter after the operating system is installed.

Call a method with complex data type from a DLL file

Hi,
I have a win32 API with a dll file, and I am trying to call some methods from it in the labview. To do this, I used the import library wizard, and everything is working as expected. The only problem which I have is with a method with complex data type as return type (a vector). According to this link, import library wizard can not import methods with complex data type.
The name of this method is this: const std::vector< BlackfinInterfaces::Count > Counts ()
where Count is a structure defined as below:
struct Count
Count() : countTime(0) {}
std::vector<unsigned long> countLines;
time_t countTime;
It seems that I should manually use the Call Library Function Node. How can I configure parameters for the above method?

You cannot configure Call Library Function Node to call this function. LabVIEW has no way to pass a C++ class such as vector to a DLL.

Cannot log into T61 from remote computer with wired network and Windows Explorer.

Hi,
I am using a T61 7662-cto with Windows 7 Professional
When the T61 is connected on the home network with the wired network, I am not able to log into it remotely from another computer. On my second computer, I see the T61 with Windows Explorer but instead of getting the login window, it appears a Network Error with the message:
“Check the spelling of the name. Otherwise, there might be a problem with your network.” With a error code 0x80070035, “The network path was not found.” I tried the “Diagnose” button but it doesn’t give solution.
When the T61 is wireless connected, there is no problem. I can access it from my second computer.
I never have problem to connect to the second computer from the T61 with any connection type . I just updated the Intel Wireless LAN (bg, abg, abgn) for Windows 7 – ThinkPad, with the drivers required but it changes nothing.

Web service call problem with complex types input

We are trying to call a web service and pass as parameter
some complex types. When invoking the web service everything works
well on flex side, but on the server side the input parameters we
get from flex are not correct - complex type is removed and the
elements of the complex type are sent. See the example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute">
<mx:WebService id="ws_id" wsdl="link" useProxy="false"
fault="wsFault(event)">

<mx:request>
<parameters>
<parameter1>{value1}</parameter1>
<parameter2>{value2}</parameter2>
<parameter3>{value3}</parameter3>
<parameter4>
<parameter4_1>{value4_1}</parameter4_1>
<parameter4_2>{value4_2}</parameter4_2>
<parameter4_3>{value4_3}</parameter4_3>
</parameter4>
</parameters>
</mx:request>
</mx:operation>
</mx:WebService>
</mx:Application>
on server side we get this:
<parameters>
<parameter1>{value1}</parameter1>
<parameter2>{value2}</parameter2>
<parameter3>{value3}</parameter3>
<parameter4_1>{value4_1}</parameter4_1>
<parameter4_2>{value4_2}</parameter4_2>
<parameter4_3>{value4_3}</parameter4_3>
</parameters>
Instead of :
<parameters>
<parameter1>{value1}</parameter1>
<parameter2>{value2}</parameter2>
<parameter3>{value3}</parameter3>
<parameter4>
<parameter4_1>{value4_1}</parameter4_1>
<parameter4_2>{value4_2}</parameter4_2>
<parameter4_3>{value4_3}</parameter4_3>
</parameter4>
</parameters>
Any idea how is it possible to send complex type as web
service input from flex ?

Hi,
I also have similar type of problem where I need to invoke a Web service with Complex input parameters.
I followed Susan's blog but I stuck at a point where methos getItem is created.
Can anyone tell me how to get that method for my requirement.
If possible can you guys share your solutions here.

Since you have already done some sort of reset on your Airport Express, you might as well make sure it was a "hard reset" - follow the instructions for a hard reset found at:
http://docs.info.apple.com/article.html?artnum=108044
Since your Mac is running Leopard, you need to configure the Airport Express using the Airport Utility found in the Applictions->Utilities folder. You cannot install the old software that was supplied on the CD you got with the Airport Express.
In future - if you do something bad with network settings on your Mac, do NOT try to fix it with the Airport Utility. The Airport Utility is only used to configure the Airport Express - and since the problem you have created is on the Mac and not the Airport Express, there is no need to be using the Airport Utility and especially there is no need to be resetting the Airport Express.
