im running mac osx using pearpc on my linux box (suse 9.1) the problem im having is with networking the emulated osx. the tutorial on this says i should do the following:

For Linux 2.6.x: You must enable (as a module "M" or compiled-in "Y") the following features in your kernel:
"Device Drivers / Networking support / Universal TUN/TAP device driver support" (CONFIG_TUN)
"Device Drivers / Networking support / Networking Options / Network Packet Filtering (replaces ipchains) / IP: Netfilter Configuration / Connection tracking (required for masq/NAT)" (CONFIG_IP_NF_CONNTRACK)
"Device Drivers / Networking support / Networking Options / Network Packet Filtering (replaces ipchains) / IP: Netfilter Configuration / IP tables support (required for filtering/masq/NAT)" (CONFIG_IP_NF_IPTABLES)
"Device Drivers / Networking support / Networking Options / Network Packet Filtering (replaces ipchains) / IP: Netfilter Configuration / MASQUERADE target support" (CONFIG_IP_NF_MASQUERADE)
No support for other Linux kernels.
If you have configured any of the above kernel features as a module make sure they are loaded before starting PearPC.

Could someone please explain to me how i would go about this please?

Tutorial at:
pearpc.sourceforge.net/netsetup.html#linux_host_setup

modules are located in /lib/modules/kernel_version/ iptables modules are located in /lib/modules/2.6.x/kernel/net/ipv4/netfilter/ i havent used suse before. i am not sure about the modules directory for suse.

to load modules try "modprobe module_name". modprobe will load sub modules if needed
#modprobe tun
#modprobe ipt_MASQUERADE
#modprobe ipt_conntrack
etc..

type "lsmod" to see modules which are loaded. type "rmmod module_name" to remove that module.

i hope i could help u
