Re: View and Edit system files in Ubuntu?

you don't need my sshfs part for USB networking, that's for mounting a remote directory over SSH. and it was supposed to be run on the ubuntu side :)

you didn't set up the usb0 interface on the N900. please read the link archebyte posted again, you have to edit /etc/network/interfaces on the N900 as well.

As far as I can see I have done as archebyte has said. In the link posted on setting up the usb networking it describes the /etc/network file to already be set by default. I viewed this file on my "N900 and it is as described, I cant see where it says I need to modify this file.

ah, alright. if the settings are the same it's ok, i had to edit mine.

hm, dunno what's wrong, then.
post the output of "ifconfig" on both devices (after ifup usb0) here for comparison. also try "lsmod | grep usbnet" under ubuntu after "ifup usb0", maybe your kernel module doesn't get loaded. a firewall on the ubuntu host might also be an issue.

Re: View and Edit system files in Ubuntu?

DanStarr, it looks like the N900 is fully set up and Ubuntu sees the usb0 interface but without an IP. 'sudo ifup usb0' in Ubuntu after connecting the cable. 'ifconfig usb0' on Ubuntu should now show the IP 192.168.2.14.

once the usb0 interfaces on both sides have valid IPs, you can ssh into the N900 from Ubuntu:
ssh root@192.168.2.15

or use sshfs.

Re: View and Edit system files in Ubuntu?

DanStarr, this is bascially the setup required on the client-side (Ubuntu):

1) modify /etc/network/interface per my post above
2) Connect USB cable (on the N900, select PC Suite Mode and execute ifup usb0 as root)
3) verify that the usb0 interface is recognised by running the following command in Ubuntu:

Code:

dmesg

you should see something like this in the last line:

Code:

[295050.409021] usb0: register 'cdc_ether' at usb-0000:00:1d.7-7, CDC Ethernet Device, de:59:f3:a9:fa:fe

4) Start up the usb0 interface with this (on Ubuntu)

Code:

sudo ifup usb0

5) verify that usb0 is up (on Ubuntu)

Code:

archebyte:~$ ifconfig usb0

usb0      Link encap:Ethernet  HWaddr de:59:f3:a9:fa:fe  

          inet addr:192.168.2.14  Bcast:192.168.2.255  Mask:255.255.255.0

          inet6 addr: fe80::dc59:f3ff:fea9:fafe/64 Scope:Link

          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          RX packets:22 errors:0 dropped:0 overruns:0 frame:0

          TX packets:47 errors:0 dropped:0 overruns:0 carrier:0

          collisions:0 txqueuelen:1000 

          RX bytes:4216 (4.2 KB)  TX bytes:9714 (9.7 KB)

you can now ping the N900 from Ubuntu

Code:

archebyte:~$ ping 192.168.2.15

PING 192.168.2.15 56(84) bytes of data.

64 bytes from n900 (192.168.2.15): icmp_seq=1 ttl=64 time=0.526 ms

64 bytes from n900 (192.168.2.15): icmp_seq=2 ttl=64 time=0.457 ms

6) ssh into the N900 and use the password entered when you install openssh on the N900.

Code:

ssh root@192.168.2.15

7) or use sshfs from Ubuntu using the command above

there's your problem, usb0 should have the IP address you entered in /etc/network/interfaces, 192.168.2.15
it should look the same as usb0 on the N900, with a different "inet addr".

did you do "ifup usb0" beforehand?

Re: View and Edit system files in Ubuntu?

Wow guys, thanks to your help i'm now in!! and I understand a bit more about how it all works. Thanks...

To my mind, I did everything I needed to do yesterday, i've not really done anything extra today to get it working - I think the problem I had was this "ifup usb0" thing, I may have activated it too soon, possibly on the laptop before plugging the phone in, and then when I would type it in time and time again I would get the message back that it was already activated.

The "obvious" point here was then looking at the output of "ifconfig usb0" when it showed that the command hadnt actually done as it should - likely due to my timing.

Starting fresh today with more of your words of wisdom got it sorted. I was able to confirm that the IP address now appeared in ifconfig, and straight away it worked. :)
