I have tried 3 versions of Parallels (1848 - 1922) and all of them cause a kernal panic when i enter in a valid local IP address. I have tried both with IP and with DNS resolved names, but there is no difference. Here is the setup. i have OS X Server 10.4.8 running the default apache installation. I have virtual domains that are resolved by the hosts file as well as DNS for other network machines. If i either change the hosts file on the Parallels/Windows XP SP2 instance... or point it to the local (Parallels hosting) machine's DNS.... as soon as I hit GO (or enter), when it starts the lookup.... a Kernal panic is thrown. This happens 100% of the time. The OS X Server install is clean... a 10.4.7 upgrade to 10.4.8 with all latest patches running on a MacBook. It seems that the Parallel user forums are full of happy customers... but this experience gives me great doubts... so if anyone can help it would be greatly appreciated. -Michael

Michael, May I ask you for some more detail... 1. Please stop apache 2. In OSX Terminal type 'sudo nc -l -p 80 | tee request.txt' 3. Try hitting the webserver from Windows IE 4. Switch back to the Terminal and hit Control-C 5. Start apache again 6. In OSX Terminal type 'nc <hostname> 80 <request.txt | tee reply.txt' 7. Hit Control-C again 8. Post request.txt and reply.txt here Thanks in advance.
I am getting the message: Can't grab 0.0.0.0:80 with bind I assume that this might be a problem in being able to complete your steps? and/or is this expected?
You may have to wait a little (until all previous connections are gone) after stopping apache. The other reason may be that you've omitted sudo in 'sudo nc -l -p 80 | tee request.txt'.
