Mac OSX DHCP debuging

Apple, CLI, DHCP, Macintosh, OSX
Once in a while you might want to dig deep into OSX's dhcp client and find out what dhcp packet the server sent it. A quick command to spit out this info:# ipconfig getpacket en0This produces the following output: op = BOOTREPLY htype = 1 dp_flags = 0 hlen = 6 hops = 0 xid = 1956115059 secs = 0 ciaddr = 0.0.0.0 yiaddr = 192.168.4.10 siaddr = 192.168.4.1 giaddr = 0.0.0.0 chaddr = 0:3:93:7a:d7:5c sname = dhcp.mycompany.net file = options: Options count is 10 dhcp_message_type (uint8): ACK 0x5 server_identifier (ip): 192.168.4.1 lease_time (uint32): 0x164a subnet_mask (ip): 255.255.255.0 router (ip_mult): {192.168.4.1} domain_name_server (ip_mult): {192.168.4.1} domain_name (string): mycompany.net end (none):

USB-to-Serial console for Mac (OSX)

Apple, CLI, Macintosh, OSX, Serial port, USB
Here are some notes for those of us working with Macs, who also have to deal with networking gear that usually have a serial console for local control. I recently purchased a IOGEAR USB 1.1 to Serial Converter Cable that uses the PL2303 chipset (pretty much any brand of these usb to serial converters use this chip). I was hoping that this dongle would allow me to access our network switches serial interface (which you kinda need when the switch has gone berserk). So after looking around the net I found that there is a opensource driver out there for it and that it performs better than the driver provided by Prolific (the company that manufactures the chip). So once everything was installed I hooked up the serial cable and realized that…

More aka.iPhone and Quartz Composer Experiments…..

Apple, iPhone, iPodTouch, Macintosh, OSX, Quartz Composer
So now that I have a basic OSC receiver for aka.iPhone's XY controller, I've been going through Apple's Demo Compositions -- under /Developer/Examples/Quartz Composer/Compositions -- and adding my portion of the OSC receiver to them. Here is the latest one, akaRemote-Caterpillar, which is a adaptation of "Caterpillar.qtz" under /Developer/Examples/Quartz Composer/Compositions/Interactive. Again I need to remind you to read the first Article to get started and that these QC compositions are for Leopard/QC3.0 only and require a jailbroken Ipod Touch or iPhone.

aka.iPhone and Quartz Composer Experiments…..

Apple, iPhone, iPodTouch, Macintosh, OSX, Quartz Composer
I assume you know what aka.iPhone is and what it does. If you don't please see this article over at Create Digital Motion. I've got aka.iPhone 2.1 installed on my ipod touch and while I enjoyed playing around with the accompanying MAX/MSP patch -- via the free runtime -- I wanted to see if I could get it working with Quartz Composer.Well here are my two (akaRemote, akaRemote-Particle) attempts at QC compositions that work really well with the XY controller of aka.iPhone. The XY Controller surface is the only thing I've been able to get working with QC, since  Masayuki Akamatsu (the author of aka.iPhone) tends to use the same basic "/event" OSC message with a custom number of arguments. The limitations is actually in QC in that you can…

Another day….another Leopard headache….

Apple, bug, Leopard, Macintosh, OSX
Okay as much as I like OSX and apple I have to admit, Leopard is not quite ready for consumption. Not unless you're willing to do a "Erase Install". After the weekend fun session of "Archive installing" 5 machines, I have found another bug/feature/headache. Here is how it happens:You've got Tiger (10.4) setup with multiple network locations (work, home, wireless, etc.)You do a archive install and get 10.5 installed on this machineAll your profile/homedirectory/apps get transfered over, including your network location configurations.Well, not quite. It might seem like everything is transfered, until you start wondering about WINS Servers and Windows WORKGROUP/Domain settings. You see under Tiger these two were stored under directory utility, but under Leopard they've tried to pack everything under Advanced  Network settings (Preferences/Network/Advanced...). The problem is that if…
