Restart(close and open) a new console window and continue running these commands on Rails

Setelah semalaman berkutat dengan instalasi yang error Ruby di OpenSuse 11.3 akhirnya kutemukan obatnya...

bash < <(curl -s https://rvm.beginrescueend.com/install/rvm)

restart console

Insert the following code to the last line of your .bashrc file then save your changes
$HOME/.rvm/scripts/rvm” ]] && . “$HOME/.rvm/scripts/rvm”
Restart(close and open) a new console window and continue running these commands
  • rvm install 1.8.7
  • rvm install 1.9.2
  • rvm —default 1.9.2
  • rvm use 1.9.2
  • ruby -v
  • gem update —system
  • gem install rails
  • rvm rubygems current
  • Finally

iptables










Untuk melihat DNAT yang dibelakukan di iptables:



internal:/home/fatur # iptables -t nat -L -v

Chain PREROUTING (policy ACCEPT 265K packets, 29M bytes)

 pkts bytes target     prot opt in     out     source               destination

96559 4999K DNAT       tcp  --  eth0   any     anywhere             anywhere            tcp dpt:http to:192.168.1.1:3128

    0     0 REDIRECT   tcp  --  eth0   any     anywhere             anywhere            tcp dpt:http redir ports 3128



Chain OUTPUT (policy ACCEPT 358K packets, 26M bytes)

 pkts bytes target     prot opt in     out     source               destination



Chain POSTROUTING (policy ACCEPT 523K packets, 45M bytes)

 pkts bytes target     prot opt in     out     source               destination



Untuk melihat list di chain INPUT:



internal:/home/fatur # iptables -L INPUT

Chain INPUT (policy ACCEPT)

target     prot opt source               destination

PORT01_IN  tcp  --  0.0.0.0/0            0.0.0.0/0           tcp dpt:25







Untuk melihat chain INPUT secara lebih detail:

internal:/home/fatur # iptables -vnL INPUT

    2    84 PORT01_IN  tcp  --  *      *       0.0.0.0/0            0.0.0.0/0           tcp dpt:25



Untuk melihat chain INPUT secara detail beserta line numbernya, line number disini bisa digunakan untuk mendeleted rule-rule yang ingin dibuang.



internal:/home/fatur # iptables -vnL INPUT --line-numbers

Chain INPUT (policy ACCEPT 10M packets, 7790M bytes)

12       2    84 PORT01_IN  tcp  --  *      *       0.0.0.0/0            0.0.0.0/0           tcp dpt:25





Untuk melakukan delete rules no 11 pada chain INPUT:






internal:/home/fatur # iptables -D INPUT 11   


Untuk melakukan insert rule, setelah hal ini diproses maka rules yang di insertkan akan berapa pada posisi pertama.


 
internal:/home/fatur #iptables -I INPUT -p tcp -s 212.100.apa.saja --dport 22 -j logaccept


Untuk melakukan replace pada chain yang sudah dibuat:




internal:/home/fatur #iptables -R INPUT 1 -p tcp -s 100.100.200.100 --dport 22 -j ACCEPT







Untuk melakukan drop dengan spesifikasi IP tertentu:





internal:/home/fatur #iptables -I FORWARD -d 123.123.123.123 -j DROP
 
hal ini bisa diberlakukan juga pada chain yang lain, misalnya:
 
internal:/home/fatur #iptables -I OUTPUT -d 123.123.123.123 -j DROP
 
Untuk melakukan drop packet dengan subnet tertentu :
iptables -I FORWARD -s 192.168.2.0/255.255.255.0 -j DROP
 
Drop alamat website tertentu
internal:/home/fatur #iptables -A OUTPUT -p tcp -d whateversite.com  -j DROP 




Salam
