SSHLord

Acest document presupune o masina proaspat instalata cu Ubuntu 9.10, careia ii instalam doar un ssh din setup.

1. Incepem prin a aduce la zi pachetele distributiei plus niste tool`uri folositoare.

apt-get update
apt-get upgrade
updatedb
apt-get install htop wget screen telnet subversion

2. Instalare pachete Java si Ant(build tool).

apt-get install java-package
apt-get install sun-java6-jdk
apt-get install sun-java6-jre
apt-get install ant

3. Dupa terminarea instalarii pachetelor, testam daca java s`a instalat corect, unde s`a instalat si ce versiune avem.

sshlord@black:~$ which java
/usr/bin/java

sshlord@black:~$ java -version
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) Client VM (build 16.3-b01, mixed mode, sharing)

4. Descarcare si compilare Red5 cu Ant.

svn co http://red5.googlecode.com/svn/java/server/trunk red5

export JAVA_HOME=/usr/lib/jvm/java-6-sun-1.6.0.13/
export ANT_HOME=/usr/share/ant/

cd red5
/usr/share/ant/bin/ant

5. Daca compilarea s`a incheiat cu succes, putem porni Red5.

sshlord@black:~$ cd red5/dist/

./red5.sh &

6. Inainte de a merge mai departe, putem testa daca Red5 a pornit si asculta pe portul default 5080.

sshlord@black:~/red5/dist$ netstat -ant
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
...
tcp6 0 0 0.0.0.0:5080 :::* LISTEN
...

7. In acest moment puteti deschide un browser si navigati la

http://[domeniu]:5080/

si ar trebui sa vedeti pagina Red5 de mai jos…

8. Daca totul a decurs corect si puteti vedea pagina de start Red5, puteti urmari un scurt demo, cum sa instalati cateva aplicatii demo si cum sa le testati.

Aceiasi pasi ii puteti urma si pe un Ubuntu 9.04…

#!/bin/bash
# Get all domains
_dom=$@

# Die if no domains are given
[ $# -eq 0 ] && { echo "Usage: $0 domain1.com domain2.com ..."; exit 1; }
for d in $_dom
do
_ip=$(host $d | grep 'has add' | head -1 | awk '{ print $4}')
[ "$_ip" == "" ] && { echo "Error: $d is not valid domain or dns error."; continue; }
echo "Getting information for domain: $d [ $_ip ]..."
whois "$_ip" | egrep -w 'OrgName:|City:|Country:|OriginAS:|NetRange:'
echo ""
done

Dependinte:

whois

Instalare whois Debian/Ubuntu:

apt-get install whois

Scriptul trebuie sa fie executabil:

chmod +x script.sh

Cum folosim scriptul?

./script.sh yahoo.com google.com

Output:

Getting information for domain: yahoo.com [ 67.195.160.76 ]...
OrgName: Yahoo! Inc.
City: Sunnyvale
Country: US
NetRange: 67.195.0.0 - 67.195.255.255

Getting information for domain: google.com [ 74.125.77.147 ]...
OrgName: Google Inc.
City: Mountain View
Country: US
NetRange: 74.125.0.0 - 74.125.255.255

Astazi Nvidia a lansat noua placa video GeForce GTX 465.

Majoritatea hardisk-urilor noi vin cu S.M.A.R.T(Self-Monitoring, Analysis, and Reporting Technology). Aceasta tehnologie permite monitorizarea hardisk-urilor si raportarea eventualelor probleme in speranta de a preveni eventualele pierderi de date.

Pentru sisteme Debian/Ubuntu:

sudo apt-get install hddtemp

Sau puteti instala din surse. Descarcare sursa:

wget http://download.savannah.nongnu.org/releases/hddtemp/hddtemp-0.3-beta15.tar.bz2

Dezarhivare si instalare din surse:

tar -jxvf hddtemp-0.3-beta15.tar.bz2
cd hddtemp-0.3-beta15
./configure
make
sudo make install

Cum monitorizez temperatura?

Pentru a vedea temperatura /dev/sda

hddtemp /dev/sda

Output-ul va fi de forma:

/dev/sda: WDC WD2500YS-01SHB1: 25°C

Output-ul de mai sus imi arata ca hardisk`ul meu are 25°C.
