 mas arif bisa tolong bantu memberikan link2 referensi mengenai hal ini?

http://l7-filter.sourceforge.net/HOWTO

 saya menemukan satu artikel cukup menarik :
 http://www.linux.com/learn/tutorials/305767-bandwidth-monitoring-with-iptables
 

Mirip yang berbahasa indonesia:

Monitoring Trafik Network Menggunakan iptables dan MRTG
Monitoring Trafik Network Menggunakan iptables dan MRTG

 saya ingin merubah dari alamat IP ADDRESS menjadi domain, contoh
 
 # domain A Downloads
 iptables -A FORWARD -d 192.168.1.0/26 -j domain-a
 
 # Town A Uploads
 iptables -A FORWARD -s 192.168.1.0/26 -j domain-a
 
 
 destination  source saya ingin rubah ke domain, bagaimana mengganti 
 perintahnya ya?

man iptables

Tidak disebutkan domain melainkan hostname, namun ini adalah ide
yg jelek:

[!] -s, --source address[/mask][,...]
   Source specification. Address can be either a  network  name,  a
   hostname,  a  network  IP  address  (with  /mask), or a plain IP
   address. Hostnames will be resolved once only, before  the  rule
   is  submitted  to  the  kernel.  Please note that specifying any
   name to be resolved with a remote query such as DNS is a  really
   bad idea.  

Pakai ip atau subnet sudah cukup jelas.

Ngomong2, tujuan pakai domain itu untuk apa?

[tanya-jawab] Setting modem simbox Wavecomm Q2406B USB 8 port

2012-10-13 Terurut Topik Yo2 United 
Dear All,

Mohon pencerahan nya donk. Saya mo setting modem Wavecomm Simbox Q2406B 8 port 
di fedora 16.
Saat saya coba mencari settingan modem tsb dgn wvdialconf ... tp modem tsb 
tidak di temukan/ tidak terdeteksi.
Padahal saat saya cek pakai dmesg :

Tapi saat di cari configurasi nya dgn wvdialconf :

Sorry, no modem was detected!  Is it in use by another program?
Did you configure it properly with setserial?

Please read the FAQ at http://alumnit.ca/wiki/?WvDial


Kira2 solusi nya apa nya untuk mendapatkan konfigurasi modem tsb ? Atau mesti 
menggunakan cara atau aplikasi yang lain.
Terima kasih
