RPCEMU

How can i setup rpcemu network under windows 7? i have tried to start bridge rpcemu but under internet configuration it says no inteface.

Have you looked at:

http://www.marutan.net/rpcemu/manual/net-win.html

These instructions are for Windows XP but they can be followed for Win7 also. When you’re finished, you should have (in Control Panel>Network and Internet>Network Connections) 2 new connections: Network Bridge, and rpcemu. The rpcemu connection will say ‘Enabled, bridged’ but when you open it, ipv4 and ipv6 will not be connected; this is OK. Opening the Network Bridge connection, it should say ipv4 Connectivity = internet, and you should see Bytes being sent and received under Activity. Hope this helps. If you are planning to use RPCEmu seriously, have a look also at

I have found that guide but the connection doesent create.
I have installed only tap like the description.

You can test to see if the interface has been created: in the RPCEMu desktop, type Ctrl-F12 to open a Task Window. At the *, enter:

ifconfig -a

and you should see something like this

‘lo0: flags=8049 mtu 16384
        inet 127.0.0.1 netmask 0xff000000
rpcem0: flags=8863 mtu 1500
        inet 192.168.0.11 netmask 0xffffff00 broadcast 192.168.0.255
        ether 06:02:03:04:05:06’

Next step is to try and ping your home network gateway (router): at the * prompt, enter

ping -c 4 192.168.X.X [insert correct numbers for your gateway]

RPCEmu will then send packets to the router and receive them back, you should get 100% success if the network is correctly configured.

Now i have a ipv4 bridge connected but when i choose ethernet bridge rpcemu under RPCEM network i get this error: Tap-Win32 Could not Open ‘rpcemu’.
Thanks

i have made ifconfig -a the result is only a lo0 interface not the rpcemu one.

Matteo, are you using RISC OS 5 or RISC OS 4 with RPCEmu? Networking functions with Win7/RPCEmu/RISC OS 4.02 (for example, on my setup here) but was not available on 5.17, though 5.19 may have fixed that. If you are using 4.02 I will do my best to help; if you are using 5.19, the best thing is to join the RPCEmu mailing list, where there is a lot of expertise: http://www.riscos.info/cgi-bin/mailman/listinfo/rpcemu

I think it’s 5.19 the one from rool emulate usb stick. Thank you for your help : ).

Have the same problem but on Ubuntu 10.04 using the versions of ROOL USB stick. i.e. ROM 5.19

On both Ubuntu 10.04 and Linux Mint Debian Edition I have used a shell script to start rpcemu. This essentially contains:

cd /opt/rpcemu
iptables -I FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -t nat -A POSTROUTING --source 192.168.3.0/24 -o eth0 -j MASQUERADE
sysctl -w net.ipv4.ip_forward=1
sysctl -w net.ipv4.ip_dynaddr=1
./rpcemu

It’s started with gksu. Networking works like a charm.

“It’s started with gksu. Networking works like a charm.”

Does not work for me. Cannot config under RISC OS as no interface.
Not sure what I missed

Okay I had assumed that the hostfs files from the RPCEmu source were already in the hostfs directory as supplied by the USB stick. Can now config Interface under RISC OS.

Now from RISC OS I can ping the TAP addresses and also my PC’s ip address 192.168.1.2 but not my router 192.168.1.1

Okay found problem. Had firewall ufw enabled on my Ubuntu system, Can now ping router and outside World

Can anyone provide me with some iptables commands to set up the UDP port forwarding necessary to get ShareFS working? I am aware of which ports are used, but despite reading the man pages for iptables I cannot work out what combination of options I need.

I have rpcemu 0.8.9 running on Ubuntu 12.04 and have some problems with bringing up the configuration menu. The ctrl,end key combination seems not to work in Ubuntu 12.04. I have tried different window managers (gnome, kde, …) and get no menu. Is it possible to build rpcemu with an other key combination ? How is it possible to trace down this nasty bug ?

This question about ctrl-end comes up quite frequently!

The keypress is being grabbed by something else before RPCemu gets to see it. IIRC it is one of the accessibility options – does the mouse pointer flash or gain some sort of highlight whenever you press ctrl-end?

The mouse pinter does not change when I press ctrl-end. Another thing is that I get the message from RPCemu that the “jack server is not running or cannot be started”. Is this a problem ? I had RPCemu working in earlier versions of Ubuntu, so what is different in 12.04 ? Do you have access to a machine with Ubuntu 12.04 ?

No, I’m still using 8.04 LTS!

These sort of problems are better discussed on the RPCemu mailing list where the developers are more likely to see it:

http://www.riscos.info/cgi-bin/mailman/listinfo/rpcemu

I think this forum is more for problems specific to running RO5 on RPCemu.

BTW, found the ctrl-end fix I was referring to:
