A Note on Updating Weaponized Nokia N900s

15 Comments

I wanted to make this post to save time and headaches for people who own ‘weaponized’ Nokia N900s.

If you regularly update your Nokia N900 by doing (as root):

apt-get update && apt-get upgrade -y

I have ran into some issues with some of the newer packages.

Firstly, the newest beta version of nmap (5.59BETA1_armel) appears to be buggy enough to the point where it’s almost unusable.

Running this:
nmap -sS -P0 -vv www.google.com -p 80

Yields:
Starting Nmap 5.59BETA1 (http://nmap.org) at 2011-12-17 21:14 EST
Warning Hostname www.google.com resolves to 6 IPs. Using 74.125.45.147
route_dst_netlink: can’t find interface “wlan0”

Secondly, subversion (svn) gets completely broken due to a library compatibility issue:

svn -h
Segmentation fault

There has been discussion on this: http://talk.maemo.org/showthread.php?p=970467

Having svn broken really stinks, because then I am not able to update Metasploit. Who in the hell wants to run an outdated version of Metasploit? (I imagine there are some people..)

To work around this for the time being I have crafted the following shell script:

#!/bin/bash

if [ ${#} -lt 1 ]
 then
   echo "Usage:	"
   echo "./update.sh normal #This just does a normal update";
   echo "./update.sh modded #This will do a normal update and then downgrade libaprutil1, libapr1 and nmap so that they work";
   exit 1;
fi

if echo ${1} | egrep "normal"  > /dev/null;
 then
   apt-get update;
   apt-get upgrade -y;
   exit 0;
elif echo ${1} | egrep "modded"  > /dev/null;
 then
   apt-get update;
   apt-get upgrade -y;
   apt-get install nmap=5.50-2 libaprutil1=1.3.9-2 libapr1=1.4.2-1 --force-yes -y;
   apt-get clean && apt-get autoclean;
   exit 0;
else
   echo "I don't know what you are trying to do.." #Thanks Arc
   exit 2;
fi

SHA1 (update.txt) = d83306d18a146a54a38ea236e3a236b4955bb81b

For the time being if you’re in a similar case like me, you’ll have to use this shell script (wget http://zitstif.no-ip.org/update.sh &&  chmod +x update.sh && ./update.sh modded).
