More BeagleBone linux

More Angstrom tools:

systemd, is a system and service manager, a initd replacement

systemd uses journal instead of syslog

journalctl – a “/var/log/messages” replacement

configuration file: /etc/systemd/journald.conf

journalctl can be used in conjuction with grep

opkg – the package manager, a ipkg fork

page: http://code.google.com/p/opkg/
download: http://code.google.com/p/opkg/downloads/list

updating the system :  opkg update (?)
package information: opkg info <package name>
install packages:  opkg install <package name>    (ex. samba, a good way to build windows networks)

top  – shows running tasks

top with no arguments  – shows all tasks

top -p <pid> –shows only that specific pid

nmap on BeagleBone

Installing nmap on BeagleBone

Maybe the best network scan tool available, the powerful nmap is also free.

http://nmap.org/

Install sequence:

wget http://nmap.org/dist/nmap-6.25.tgz
cd nmap-6.25
./configure
make
make install

The install procedure takes some time (>20 minutes)
To get the basic help run nmap without arguments.

the make step is displaying 2 errors but is ok, make install shows 1 error but it works.

BeagleBone running Matt’s traceroute – mtr

Installing mtr on a Beaglebone/Angstrom

mtr(former Matt’s traceroute) is a mix of traceroute and ping, I use it often in network diagnose. Running it on BeagleBone simplifies many things.

As a usual source install:

wget ftp://ftp.bitwizard.nl/mtr/mtr-0.82.tar.gz
tar -xzvf mtr-0.82.tar.gz
cd mtr-0.82
./configure
make
make install

well… cursesX is not available… but is ok, I don’t want to run X.

mc on beaglebone

Midnight Commander 4.6.1 running on BeagleBone with Angstrom Distribution.

BeagleBone is a linux box. So get all the classic linux tools!

Midnight Commander on BeagleBone

mc aka Midnight Commander is a visual file manager (orthodox file manager) used in console work. It is released under under GNU GPL.

For those who are not familiar with mc it is a product in the line of nc – Norton Commander, Path Minder, dn – Dos Navigator, far, Windows Commander / Total Commander.

mc v4.6.1 runs smooth on BeagleBone/Angstrom, mc v4.8.1.7 needs the S-Lang Library (http://s-lang.org) so I skipped it.

Installing mc from source is simple but it takes some time for every step, is not like installing it on a server but you have enough time to read the full output without redirecting it to a file 🙂

wget http://www.midnight-commander.org/downloads/mc-4.6.1.tar.gz
tar -xzvf mc-4.6.1.tar.gz
cd mc-4.6.1
./configure
make
make install
