Packet writing on Mac

I have finally figured out how to use packet writing on Mac OS X. This information had to be shared. The software needed for writing to a DVD like a floppy disk is already in Mac OS 10.6. I think the main problem is trying to format a DVD in the UDF format. There is a quick and easy way to do this. Just format the disk in a Windows 7 machine using the "USB flashdrive like" option. I realize this is not what many people wanted to hear. The program to do this on a Mac is called newfs_udf. But I really doubt anyone out there has ever figured out how to make it work. But please prove me wrong! I know all my attempts to make it work have failed.
I have to say that packet writing is one area that Microsoft out does Apple. Formatting and writing to a DVD is so much easier on Windows 7. I wish I had some blu-ray disc and a burner to try this feature, but I don't. The speed on my PC was up to 4.5 MB/s for most of the writing. That is a usable speed. No were near flash drive territory, but not bad. On the Mac, it was much slower. Mac OS X doesn't report the speed of a copy like Windows 7 does, but I would guess it was in the 1 MB/s range.
Info:
Used MacBook Pro running Mac OS 10.6 and a PC laptop running Windows 7. The disc I used was a 4x DVD-RW.

I finally figured out a way to format a disc for packet writing on the Mac! Just download this blank UDF disc image of a DVD, then use Disk Utility to burn it to disc.
http://www.mediafire.com/download/1h2bahvwv3wy5ws/UDF_2.01_formatted_DVD.dmg.zip
Steps:
1) Download this image file: http://www.mediafire.com/download/1h2bahvwv3wy5ws/UDF_2.01_formatted_DVD.dmg.zip
2) Unzip the file by double-clicking on it
3) Open /Applications/Utilities/Disk Utility
4) Push the Burn button in Disk Utility
5) Select the disc image file
6) Insert a blank DVD RW disc to burn the image file onto it
The end result is a disc that can be written to like a floppy disk! DVD+RW and DVD-RW should both work. Use something in the range of 4x to 8x speed to reduce the wait time.

Router receives a frame/packet with unknown MAC address

Hi Everyone,
Lets assume that a router received a frame/packet on an interface due to switch did not have the destination mac address listed on its mac address table and therefore broadcatsed this packet out of all ports, and router receives that packet that was not even intended to reach it. Would the router route that packet or drop? Just wondering if my assumption is true and router would drop a frame/packet that it receives on an interface if the destination MAC address of this frame/packet is not a MAC address of the routers's interface that it was received on.
Thanks!

Hey but I don't think router ever does a destination mac check! (that's surprising indeed), looks like router does not check the destination information, until it strips off ip packet from the frame! have a look at what a router does when it receives a frame (with any destination mac addr) here:-

Reading / writing a MAC drive on a PC - how to?

Could somebodybody please tell me how to access the information and write on a MAC drive (external USB, MAC formatted) on a PC?

To share data between your Mac OS X and Windows partitions:
When you’re using Windows, you can open and view files on the Mac OS X partition. To modify a
file, copy it to your Windows partition.
If you can’t see your Mac OS X partition when you’re using Windows, update Boot Camp.
Upgrading Boot Camp
When you’re using Mac OS X, you can view and open files on your Windows partition. If the
Windows partition uses the MS-DOS (FAT) format, you also can modify files on your Windows
partition. Otherwise, copy a file to your Mac OS X partition to modify it.
To see the format for your Windows partition, select it in the Finder, choose File > Get Info, click
the disclosure triangle next to General, and look at the Format field.
You can format an external disk so you can use it with both Mac OS X and Windows. For more
information, open Disk Utility (in the Utilities folder in the Applications folder) and search for
“formatting a disk for Windows.

SG300 inter-VLAN routing and MAC address changes in incoming packets

Hello
I have SG300-20 working in Layer3 mode
VLAN1 is not used
Internet gateway is in VLAN211
Clients are in other VLANs
Switch is default gateway for clients and itself has internet gateway as default route.
MAC address of switch is XX:XX:XX:XX:XX:63
When client sends trafic to Internet destination MAC address in outgoing packets is XX:XX:XX:XX:XX:63
But in incoming packets source MAC address is XX:XX:XX:XX:XX:69
Why does it change? And how can I setup switch to use only XX:XX:XX:XX:XX:63 MAC address?

Hi Robert,
I'd like to pick up this old thread because we have a huge problem with the behavior of the SG300 router/switch regarding the "spoofed" MAC source addresses. We have connected this switch to another router which has some special routing capabilities. It routes certain IP packets directly to MAC addresses which it learned from snooping on special traffic.
When connected to a SG300 router with an Ethernet base address of XX:XX:XX:XX:XX:48 we receive packets with Ethernet source addresses like e. g. XX:XX:XX:XX:XX:49 or XX:XX:XX:XX:XX:4D (depending on which hardware port they came from). Our special router "learns" these MAC addresses and tries to send associated outgoing packets directly to these addresses using e. g. XX:XX:XX:XX:XX:49 as the MAC destination address.
Our problem is that the SG300 does not forward the packet if the MAC destination address is not equal to the switch's Ethernet base address (XX:XX:XX:XX:XX:48 in our case). This renders the SG300 series useless for our systems.
Is there new firmware available which fixes this problem for us? We don't care which MAC source address the SG300 uses in incoming packets we receive, but we expect that the SG300 handles packets correctly for outgoing packets we send with this MAC address as the destination address.
Thanks,
Chris

New to Mac--how do I save filed to a CD

On my PC, I'd insert a blank CD-RW disc, format it, and just leave it in my drive. Anytime I wanted to save a file, whether it was a Word document or a photo, I'd click Save As, and when it prompted me for where, I'd click the disc (Drive G), and presto, the file would go to the disc, and I could rewrite it any time I want. I've been trying for over an hour to do that on my new iMac, and I don't see how. I've been through the Help section over and over and can't figure out how to do this. Any help would be appreciated. I see how I can make a disc one time by selecting a lot of files and burning them simultaneously, but I don't see how I can just format a disc for read/write access, and leave it in my drive to save files to it with just one click. It was so simple on my PC. Is it even possible on a Mac?

I think what you are talking about is packet writing to CDRW media now called a version of UDF, I believe. AFAIK that doesn't exist on the Mac, but I could be wrong. There used to be an Adaptec product called DirectCD that did UDF on the Mac.
Some old information: http://www.sweetwater.com/expert-center/techtips/d--01/12/2001
And wiki information .. http://en.wikipedia.org/wiki/UniversalDiskFormat States UDF 1.5 on Mac 10.4.5 only supports the plain style of UDF writing.
Those articles also discuss reasons NOT to do packet writing as well as compatability problems.
I would suggest a cheap $30 2GB flash stick.

HT3231 Transferring photos from PC to Mac Pro using a DVD-R Disk

I've downloaded some photos from my PC onto a DVD-R disk and my MacPro does not recognize that disk. What am I doing wrong?

Patricia 90 wrote:

You don't download files to an optical disc, you write them (or, informally, burn them) to the optical disc.
and my MacPro does not recognize that disk.
What exactly happens when you insert the disc? Is the DVD-R not mounted on the desktop, although Finder prefs are set to display such devices on the desktop?
What am I doing wrong?
Hard to say without more details. What application did you use on PC to write the DVD-R? What format did you use? By and large Mac OS X should be able to use the usual data formats (UDF, ISO9660). But you will have problems with packet-writing (InCD, DLA).

Writing to DVD as if it were a floppy (packing writing)

I am a pc user switching to mac...
In windows, I used a program from Nero that allowed me to write to a DVD as if it were a floppy (ie drag and drop). I seem to remember is was called packet writing. Is there similar capability in Mac? Is it native or do I need a 3rd party app?
Thanks
bob

What is it you really want to do? Personally, I use a thumb drive exactly the way one used to use floppies. Plug it in, drag files to it, eject it. Later on you plug it in again and drag more files to it and delete files from it you no longer need. Of course, while they are pretty cheap these days (I've seen 1GB thumbs for $6), if you are giving away the disks to someone else this wouldn't be the best idea, which is why it would help to know what you are doing.
Both Windows and Mac programs use a bit of trickery to add files to a burnable disk, and the trickery is not really compatible between the platforms, so if you want to share files by way of disks between a Mac and Windows computer a FAT32 formatted drive is the better option. So, again, what is it you are trying to do?

Can you read/write to Mac partition from Windows 7 partition with bootcamp?

Hi there. I am about to take delivery of a new Air and want to install Windows on it. As accessing both simultaneously isn't important to me, I don't mind using boot camp and would like the performance gains (if there are any?) of booting straight into either.
The question is: would I be able to, from Windows, access and edit (have full access to) files stored on the Mac partition?
Furthermore, does anyone know whether I could run itunes on both using the same set of files (i.e. exactly the same itunes whether in OS X or Windows?).
Thanks very much for your help. I have heard contradictory things so wanted to see what the real answer was!
Thanks,
Tom.

iTunes has to be somewhere you can write. There are some tips on iTunes probably in the devoted forums.
But writing to Mac partition (HFS+) requires 3rd party driver. Same for writing to NTFS from Mac OS.
I would not recommend MacDrive8 for allowing Windows to write to Mac HFS, but that is and was the first to do so. Paragon-Software has been creating some file system drivers for Windows, Linux and now Mac to go both ways. Most of their products are in the backup & recovery and partitioning area.
Apple has added read-only feature to allow accessing HFS but the feature (and it is not really a service or driver that you can turn on/off or choose to not install, it is part of the Boot Camp package) has been known to need to be renamed/deleted. Not always but will sometimes trigger BSOD. Maybe reading a file with a file name? doubt it but I rename "AppleHFS" and "AppleMNT" so they don't load or function in Windows 7.

Wifi packet loss after upgrading to 10.7.4

After upgrading all three macs (mb pro, mb air, imac) in the house to 10.7.4 they all experience wifi packet loss. I ping to the local router. I have connected to a multitude of wireless routers with similar result.
But here is strong evidence that is a the OS X software problem. I am running linux inside of vmware fusion. I have run the exact same ping commands simultaneously in (1) mac and (2) vmware linux. The linux ping experiences zero packet loss, not even a single packet. The mac at its best will lose 1% packets, but can increase beyond that.
We are suffering from slow internet in our corrent location as it is, and this has a noticable impact on our performance. I am a bit afraid to upgrade to Mountain Lion for fear it may be even worse.
Any thoughts?

Your
com.apple.systempreferences.plist
file is likely corrupt in your
(use the Finder > Go > Go To folder and paste & Go)
~/Library/Preferences
folder, Trash the flle you can (may be two of them, one is a lock file) and reboot.
Reset your system preferences again.

I was able to get this to work, using the same configuration you mention. The way I did it was to set up the IP address on my LAN using fixed static addresses, and to have the router "forward" the http packets to the Mac running Apache. In Network system preferences panel, you also need to set the DNS servers address to the address of the router on the LAN. In order to reduce hackers trying to break in, I don't use the standard port 80 for my address, but use some other 4-digit port (e.g., 8182), so my website address ends up looking like www.whatever:8182. Instead of "no-IP.com" I used the free dynamic name service from http://www.dyndns.com/. I also put the web content on a firewire disk, which requires a little editing of the httpd.conf file. This was another security precaution. Anyhow, its been working great -- not a single problem. Also, Weblock is great shareware that lets you assign login IDs on the web folders.

SG200 Switch not forwarding Packet

Hello,
I have a problem with my SG200-08 Switch the switch not fowarding a special Packet.
I try to run a simple Profinet installation for testing on the switch but it didn´t work correct. A special packet (Profinet error message) was not forwarded.
I have tried it with different Profinet masters with Siemens Profinet master it works without of problems. With Rexroth master it dosn´t work. But it is the same packet only another Mac Address.
I have added two Wireshark logs, where I have mirrored the slave and the master port. With the Siemens master all packets are forwarding (every packet is double loged) with the Rexroth master the alarm packet was not forwarding (the alarmpacket is lost between the ports).
With a not managed Switch it is no problem too run both Installations korrekt.
I have tried the Factory devault Settings of the switch and too deaktivate all services of the switch (like Spanning Tree, ..) but it was all the same, the Packet was not forwarded.
Has someone a idea which is the cause of the packet drop?

Hi Ulf, the switch doesn't filter traffic and this particular model doesn't have any special connection controls like ACL.
Features that may be service affecting include-
Spanning tree (portfast, bpdu flood/filter)
Port negotiation (speed/duplex)
Energy efficient ethernet
Bonjour discovery
Storm control (which is disabled by default)
I couldn't think of anything else that may be service affecting. You may disable spanning tree, manually set the port speed, disable EEE and bonjour if you want. However, I don't feel it will resolve your problems but it is worth trying if you feel the switch is the problem. Since the packet is forwarding correctly, it would appear to be a localized system setting.

ISP blocks my APBS due to various MAC addresses used by the router

Hi all,
My Internet provider limits access to Internet over Ethernet cable
for fixed MAC address(s). That means, I have to inform ISP of the
only MAC address I'll use to transfer data. In the case ISP detects
traffic with other MAC addresses on my cable, he blocks any traffic
at all (until cable unplugged and kind of 30secs are waited).
My configuration is APBS GigaN with "shared public IP" and with
MacBookPro connected over embedded WiFi AirPort N card.
I reported EthernetID of my APBS to ISP, but stuck into the problem
that all the time router is blocked. It successfully receives
IP settings from DHCP of provider, and then passes nothing in/out.
The provider said he can see the packets with different MAC addresses,
as I understood these MACs are exactly AirportID and EthernetID of
APBS. Why is it happening so, when "shared public IP" with DHCP
and NAT are selected? Why MAC address of wireless card of APBS is
visible to outside? What can I do with it, supposing that provider
can't fix the case on his side?
Regards,
Strim

kevj is right, Your linksys router has 3 MAC address and they all are assocciated with each other.

Programming for the mac without using xcode

Hi
I'm very new to programming for Apple platform. I wanted to clear some doubts which is currently standing as a barrier in getting started.
Can I use a text editor (preferably TextMate), Interface Builder, and the Terminal (without using xcode to write & compile) to develop software for the Mac. I have installed the xcode package (~900 mb image).
Can you point me to some resources on terminal commands for compile, debug codes for the mac. (Obj-C, Cocoa api)
Thank You.

You can use anything you want to develop software for the Mac. In fact, I always encourage people to start out with tutorials and examples using standard UNIX command line tools like vi and gcc. There are plenty of such getting started tutorials for UNIX and Linux.
At some point, however, the command line is going to get cumbersome. You may want go start writing true Mac applications instead if command line tools. Then it will be time to start with Xcode.
