qualche novita' interessante

[Maurizio Marini]

Grazie al contributo di un amico che ha postato su altri forum, sono venuto a conoscenza della possibilita' di attivare un tunnel ppoe da dietro il router di alice.
In pratica, qualsiasi host capace di attivare una connessione pppoe, behind router, quindi con ip nattato 192.168.1.x, alzando (/sbin/ifup) una connessione pppoe si vede assegnato un ip pubblico sulla ppp0.
Ecco qua:

[code]
** Summary of what you entered **

Ethernet Interface: eth0
User name:          pippo
Activate-on-demand: No
DNS:                Do not adjust
Firewalling:        NONE
User Control:       yes
Accept these settings and adjust configuration files (y/n)? y
Adjusting /etc/sysconfig/network-scripts/ifcfg-ppp0
Adjusting /etc/ppp/chap-secrets and /etc/ppp/pap-secrets
  (But first backing it up to /etc/ppp/chap-secrets.bak)
  (But first backing it up to /etc/ppp/pap-secrets.bak)



Congratulations, it should be all set up!

Type '/sbin/ifup ppp0' to bring up your xDSL link and '/sbin/ifdown ppp0'
to bring it down.
Type '/sbin/pppoe-status /etc/sysconfig/network-scripts/ifcfg-ppp0'
to see the link status.

# /sbin/ifup ppp0
ifconfig

sto penando a come bypassare il discorso associazione usando opportunamente queste connessioni (se ne psossono attivare piu' di una anche sullo stesso host)

[Maurizio Marini]

argh!
di queste connessioni pppoe gia' parlava Emanuele 3 anni fa

ok, staimo pensando che usando le credenziali del voip si ottenga la mitica pppoe sul 192.168.200.1

Lecredenziali si ottengono decritatndo il backup:

[code]
openssl aes-128-cbc -K 65316532656263323039373831383630 -nosalt -iv 0 -d -in
AGConfigddmmyy.kry -out AGConfigddmmyy.xml
[/code]

grep routed AGConfig250712.xml                                                                                                                                                     
                <Username>N100920E0...@aliceres.routed</Username>
grep Password AGConfig250712.xml

una di queste sere provo il tutto :)
e vi aggiorno
