Getting started with the SheevaPlug

My SheevaPlug finally arrived. Ordered the morning (EDT) of April 1st and arrived May 12th.

Getting Started


  • Connect the provided mini-USB & network cable to SheevaPlug


  • On desktop do this to load the right driver. sudo modprobe ftdi_sio vendor=0x9e88 product=0x9e8f


  • Install and run gtkerm Set the default port to /dev/ttyUSB1 and 11850 8N1 for the connection. I saved it as the default configuration to make like easier later.


  • Apply power and watch the boot via the console



Initial Configuration

Default root password is nosoup4u, changed to something else...

NB: ssh-server already installed

Set the hostname to LordShiva

Better apt caching

Add to local apt caching by adding /etc/apt/apt.conf. I already have apt-cacher setup on the 192.168.1.234 host.

Acquire::http { Proxy "http://[192.168.1.234]:3142"; };

Let apt work better

Because the /var/cache/apt/archives/partial is on a tmpfs, it gets removed on reboot. Create it manually (should add this to the rc.local)

mkdir -p /var/cache/apt/archives/partial

Update the pre-installed Ubuntu

apt-get update

Fix clock

The time was initially set to Sun Jun 23 10:26:13 UTC 1963

I've not fixed the nameserver yet, so point ntpdate to the ip address of ntp.ubuntu.com (91.189.94.4)


root@LordShiva:~# ntpdate 91.189.94.4
13 May 02:30:20 ntpdate[1362]: step time server 91.189.94.4 offset 1448118269.109798 sec



Something strange with /etc/resolv.conf

This is what it has, but there is no DNS server running on the SheevaPlug.

domain mv.com
search mv.com
nameserver 127.0.0.1


Fix it manually to point to my local ISP.

domain mv.com
search mv.com mv.com
nameserver 199.125.85.1
nameserver 199.125.85.2

ARG! I CAN"T LOG IN

The new root password doesn't work!

''Fortunately'' it is a known problem. See
http://openplug.org/plugforum/index.php?topic=110.0


To fix:

Use serial line and catch (press any key) on boot.

Marvell> printenv bootargs
bootargs=console=ttyS0,115200 mtdparts=nand_mtd:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) rw root=/dev/mtdblock1 rw ip=10.4.50.4:10.4.50.5:10.4.50.5:255.255.255.0:DB88FXX81:eth0:none
Marvell> setenv bootargs console=ttyS0,115200 mtdparts=nand_mtd:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) rw root=/dev/mtdblock1 rw ip=10.4.50.4:10.4.50.5:10.4.50.5:255.255.255.0:DB88FXX81:eth0:none init=/bin/bash
Marvell> boot


Then fix by doing:

passwd -d root
passwd root


until you see 'passwd: password updated successfully'
