BeagleBone is great!
BeagleBone running great
install elinks:
wget http://www.elinks.cz/download/elinks-current-stable.tar.gz tar - xzvf elinks-current-stable.tar.gz cd elinks-0.11-20130125 (better press tab after elinks, the last part is the date) ./configure make && make install
and finally get to google:

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.
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.
nmap on BeagleBone
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

Later edit:
opkg install mc
