is there any output on the device screen that indicates an error of some sort ? 
does it display the "OK" in ascii ?

The device seems to be properly setup. It shows the "ok" as expected.

any other suggestions I can try out? I connected the device to a windows 
machine to see if there were any issues and i still have the same MuxError. My 
Mac is running 10.8.2. Could the cause be related?

Once again, everything seems to work - i get all OK's. I only get an error once 
i try to make the SSH connection. I have tried both on an iPhone4 and an iPad1 
- both of which should work.

Here is a patch to enable on-screen debug output of the sshd server. If you 
recompile and regenerate the ramdisk hopefully it should provide some pointers 
on what is going wrong.

done....i now see "proc: table is full"....and it just keeps repeating. The 
"OK" message still appears but then is quickly overrun by the "proc: table is 
full" messages.

Ok, i suspect somehow the sshd binary was not copied to the ramdisk (the 
build_ramdisk.sh is not very well written and its not obvious when something 
fails). I added some code in commit e53e03430837 to check if the sshd binary is 
there before launching it. Btw, which ipsw are you using to create the ramdisk 
? Thanks

ok, can you post the output of the make_ramdisk_k48ap.sh script. I tried 
creating the ramdisk with the same ipsw and sshd was copied correctly.
To check this you can edit build_ramdisk.sh and add an "exit" statement just 
before the line "hdiutil eject /Volumes/ramdisk". Then run "ls 
/Volumes/ramdisk/sbin" and check if sshd was copied successfully.
Thanks.

no, it does not look to be there...attached a screenshot for 
confirmation...looks like i must be doing something wrong but cant see where it 
would be..

Jean, i think we can close this out. I am not sure what the problem was but I 
ended up re-cloning the entire package and it seemed to work. 

The only thing i can think of is my work network prevented some downloads as 
this time i built the ramdisk off network and saw the ssh.tar download actually 
being processed. Wasn't sure if that was because i just re-cloned it or not but 
ssh was the issue we were having.

So in a nutshell, always build the ramdisk on an unrestricted network.
