Ethernet Bridging in Mac OS X 10.7 Lion

Post by NucAr »

I just discovered that you can perform ethernet bridging in the Mac OS X 10.7.5 terminal the same way that we previously thought was possible in only 10.8 and up. I guess Apple must have implemented it in a later version of 10.7 (or was it always there?). I quickly tested it with Basilisk II, and it works. So 10.7 doesn't require IPNetRouterX.

Thanks for the report! I may try upgrading to Lion on my lowly Mac mini Core Duo to see how it runs.

Would you mind doing me a small favor and executing this command in a terminal window to tell me what the output is?:

Code: Select all

/usr/sbin/screencapture -h
The version installed with OS X 10.6 doesn't support capturing windows by ID. I am wondering if the version installed with OS X 10.7 supports it?

For anyone interested, I got impatient and extracted the binary from the Essentials.pkg in the InstallESD.dmg disk image inside of the Lion installer. And sure enough, it does support the window ID method of capture, unlike the version included with 10.6:

Code: Select all

# ./screencapture -h
screencapture: illegal option -- h
usage: screencapture [-icMPmwsWxSCUtoa] [files]
  -c         force screen capture to go to the clipboard
  -C         capture the cursor as well as the screen. only in non-interactive modes
  -d         display errors to the user graphically
  -i         capture screen interactively, by selection or window
               control key - causes screen shot to go to clipboard
               space key   - toggle between mouse selection and
                             window selection modes
               escape key  - cancels interactive screen shot
  -m         only capture the main monitor, undefined if -i is set
  -M         screen capture output will go to a new Mail message
  -o         in window capture mode, do not capture the shadow of the window
  -P         screen capture output will open in Preview
  -s         only allow mouse selection mode
  -S         in window capture mode, capture the screen not the window
  -t<format> image format to create, default is png (other options include pdf, jpg, tiff and other formats)
  -T<seconds> Take the picture after a delay of <seconds>, default is 5
  -w         only allow window selection mode
  -W         start interaction in window selection mode
  -x         do not play sounds
  -a         do not include windows attached to selected windows
  -l<windowid> capture this windowsid
  files   where to save the screen capture, 1 file per screen
Sorry for the off-topic post, and now back to your regular programming... :)
