If not, I’d recommend you check the remainder of your configuration as this seems to be automatic on the newest version of SheepShaver running with Xubuntu 12.10. After you start the OS, you should be able to go to the Control Panel for TCP/IP and see that DHCP has assigned addresses in the 10.0.2.x range for DNS and IP address. While some networking functionality won’t work with this type of connection, for the most part you should be able to use this for web browsing, downloading, etc.
To activate the above change in the current session, use the command sudo sysctl -w vm.mmap_min_addr=0.This change will automatically be loaded everytime the system reboots.
Edit the /etc/nf file (as super user) and add vm.mmap_min_addr = 0 to the end of the file this corrects memory errors when running as non-root account.
The first thing I had to do was install libesd0 ( sudo apt-get install libesd0).
