Question ubuntu 9.04 ssh help please

I am following the instructions in http://openinkpot.org/wiki/SSHAccess to allow ssh access to my BeBook running openinkpot 2009 03 26.

I am pretty sure the ubuntu is a standard install. But it runs on a rather old P3 desktop with usb < 2.0.

I edited the /etc/network/interfaces file to include:

iface usb0 inet static
address 192.168.111.2
netmask 255.255.255.0


then try the ifconfig command:

ralph@en:~/BeBook$ ifconfig usb0 up
usb0: ERROR while getting interface flags: No such device

ralph@en:~/BeBook$ sudo ifconfig usb0 up
[sudo] password for ralph:
usb0: ERROR while getting interface flags: No such device

ralph@en:~/BeBook$ ifconfig -v usb0 up
usb0: ERROR while getting interface flags: No such device
WARNING: at least one error occured. (-1)


As you can see I am not getting very far. My knowledge of these things is slight. Any help/suggestions are most welcomed

regards

dmesg output

Hi Dottedmag,

thanks for the suggestion.

I restarted the computer and ran dmesg. the output (rather long) is attached.


I tried the "ifconfig usb0 up" again, then dmesg, but there seem to be no additional messages.

regards.

USB 1.1 is more than enough.

From the dmesg I can conclude your computer does not see the device at all (just to make sure: did you plug it in in powered on state?) - try another USB cable and then another computer to figure out what exactly is broken.

For the reference, Linux output the following lines to the log when something like V3 is attached:
Code:
[763343.412071] usb 3-1: new full speed USB device using uhci_hcd and address 3

progress ?

Hi Dottedmag,

from your message I gather the BeBook should be plugged in to the PC via usb cable. From the help page I thought that step came later.

Anyway I tried a few things, hoping they might throw some light on the problem. Please see the transcript below.

Thanks for your interest. Regards.


transcript follows:



I started PC normally without BeBook connected.

Ah, it's a known Ubuntu bug: use 'ifconfig usb0 192.168.111.2 netmask 255.255.255.0 up' once the device is plugged.

IIRC this way you won't need an entry in /etc/network/interfaces

Smile success - thanks dottedmag

Hi again,

this time success. Many thanks for your help. I look forward to messing around inside the BeBook.

Great. I've updated SSHAcces wiki page.

Thanks again,

the wiki looks good. The previous reference to that bug really didn't help me. Now the solution is right where you need it.

Regards Lampadena

This worked great for me, too. I've been trying (on and off) for several months to ssh into the BeBook on Ubuntu. Thanks, Dottedmag!
