I’ve enjoyed the new release of Snow Leopard for a while now, but just attached my iPod nano for the first time. Darn thing didn’t seem to want to show up in iTunes. It did it Finder, so there wasn’t anything wrong with a cable or the iPod itself.
Google/apple’s support-site didn’t say quite a lot about it, but I found the solution: Pop your Snow Leopard DVD back in your player and start the ‘Optional’ installer. You can select ‘iPod Support’ in there. Once the installer is done, restart iTunes and reattach the iPod. It is now back in iTunes.

I’ve had my share of battles with corrupt vmdk files, after the process of removing a snapshot crashed. Finally, I found a way to recover them through a VCB utility. Here’s the log that usually presents itself:
May 12 01:43:13.593: vmx| DISKLIB-DSCPTR: Failed to open extents for descriptor file in normal mode May 12 01:43:13.593: vmx| DISKLIB-LINK : “/vmfs/volumes/49dc603e-af139aaa-7131-002219b6f201/VM1/VM1.vmdk” : failed to open (Device or resource busy).

May 12 01:43:13.594: vmx| DISK: Cannot open disk “/vmfs/volumes/49dc603e-af139aaa-7131-002219b6f201/VM1/VM1.vmdk”: Device or resource busy (1048585). May 12 01:43:13.594: vmx| Msg_Post: Error May 12 01:43:13.594: vmx| [msg.disk.noBackEnd] Cannot open the disk ‘/vmfs/volumes/49dc603e-af139aaa-7131-002219b6f201/VM1/VM1.vmdk’ or one of the snapshot disks i t depends on. May 12 01:43:13.594: vmx| [msg.disk.configureDiskError] Reason: Device or resource busy.We will use the vcbExport utility to read the data from the old vmdk and create a new one. First, unregister the VM from your ESX host (if not done already):
# cd /vmfs/volumes/49dc603e-af139aaa-7131-002219b6f201/ # vmware-cmd -s unregister `pwd`/VM1/VM1.vmx unregister(/vmfs/volumes/49dc603e-af139aaa-7131-002219b6f201/VM1/VM1.vmx) = 1Then move the old VM directory and create a new one:
# mv VM1 VM1.old # mkdir VM1 # cd VM1Then, convert the old vmdk to a new one:
# vcbExport -M 1 -F 1 -d VM1.vmdk -s ../VM1.old/VM1.vmdkThis will take a while, depending on the size of your disks. After all, it is copying the entire data file. Do the same for the other vmdk’s, if you have more than one disk. After you finish with vcbExport, we need to alter a few things to the .vmdk file(s); open it in your favorite editor. Change:
createType=”monolithicFlat”To:
createType=”vmfs”Change:
RW 56124534 FLAT “VM1-flat.vmdk” 0To:
RW 56124534 VMFS “VM1-flat.vmdk”Copy .vmx and .vmxf file
# cp ../VM1.old/VM1.vmx* .After that, you can register and start the VM again:
# vmware-cmd -s register VM1.vmx register(/vmfs/volumes/49dc603e-af139aaa-7131-002219b6f201/VM1/VM1.vmx) = 1 # vmware-cmd VM1.vmx start start() = 1The VM will require an answer on the UUID matter (choose ‘Keep’) before it actually boots:
# vmware-cmd VM1.vmx answer

Incase you don’t have the luxury of PHP5′s filter_ functions, this is a handy regexp:
function validate_ipv6($ip) { $hex = ‘[A-Fa-f0-9]‘; $h16 = “{$hex}{1,4}”; $dec_octet = ‘(?:25[0-5]|2[0-4]d|1dd|[1-9]d|[0-9])’; $ipv4 = “$dec_octet.$dec_octet.$dec_octet.$dec_octet”; $ls32 = “(?:$h16:$h16|$ipv4)”; $ipv6 = “(?:(?:{$IPv4address})|(?:”. “(?:$h16:){6}$ls32″ . “|::(?:$h16:){5}$ls32″ . “|(?:$h16)?::(?:$h16:){4}$ls32″ . “|(?:(?:$h16:){0,1}$h16)?::(?:$h16:){3}$ls32″ . “|(?:(?:$h16:){0,2}$h16)?::(?:$h16:){2}$ls32″ . “|(?:(?:$h16:){0,3}$h16)?::(?:$h16:){1}$ls32″ . “|(?:(?:$h16:){0,4}$h16)?::$ls32″ . “|(?:(?:$h16:){0,5}$h16)?::$h16″ . “|(?:(?:$h16:){0,6}$h16)?::” . “)(?:/(?:12[0-8]|1[0-1][0-9]|[1-9][0-9]|[0-9]))?)”; $regex = “/^$ipv6$/”; return preg_match($regex, $ip); }
