Re: [Rpcemu] Linux for RPCemu, was Re: rpcemu for Linux

<snip of yesterday>

Two things so far today:

(a) I've also set up RPCemu on a MacBook (2015) and it works at the earth shattering rate of a stated approx 55 mips.

(b) Started to try to get networking going on the Mac and got stuck.

I suspect part of the reason is that 'RPCEmu Networking Guide' is specified for stable releases where the run command is indeed ./rpcemu

From the page 'Linux Binary Configuration' I chose the 'sudo method' and did this in Terminal:

------- Start of attempt to do 'sudo ./rpcemu' ---------

tim@tim-VirtualBox:~/rpcemu/rpcemu-0.8.102$ ls
cmos.ram hd4.hdf poduleroms riscos-progs rpc.cfg rpclog.txt
COPYING hostfs readme.txt roms rpcemu-recompiler src
tim@tim-VirtualBox:~/rpcemu/rpcemu-0.8.102$ sudo ./rpcemu-recompiler
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'

------- End of attempt to do 'sudo ./rpcemu' ---------

The result of the above was that a second iteration of RPCemu started up OK.

I then edited rpc.cfg. This may have been a mistake and should have belonged only to the 'chown method'.

Back to the RPCEmu Networking Guide and a check on the running network interfaces:

-------- Start of 'if config' --------

tim@tim-VirtualBox:~/rpcemu/rpcemu-0.8.102$ ifconfig -a
enp0s3: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

-------- End of 'if config' -------

The first of the two interfaces was (probably) the one running on Ubuntu to talk to VirtualBox.

I then tried to issue the commands on the Ubuntu interface:

-------- Start of interface commands --------

tim@tim-VirtualBox:~/rpcemu/rpcemu-0.8.102$ iptables -I FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT
conntrack: Could not determine whether revision 3 is supported, assuming it is.
conntrack: Could not determine whether revision 3 is supported, assuming it is.
conntrack: Could not determine whether revision 3 is supported, assuming it is.
iptables v1.6.1: can't initialize iptables table `filter': Permission denied (you must be root)
Perhaps iptables or your kernel needs to be upgraded.
tim@tim-VirtualBox:~/rpcemu/rpcemu-0.8.102$

-------- End of attempt at interface commands --------

You will note the error message that 'you must be root', so I definitely gave up as I knew this had to be duff.

What should I have done?
