Rete... con Ubuntu non va invece funziona con Puppy Linux!!!

[webeco]

Tempo fa ho postato di problemi (mai risolti) su un mio notebook Medion modello sim2000. Il problema è che con ubuntu non riesco ad accedere ad internet  :'(. Poco fa ho provato per pura curiosità ad avviare il cd live di puppy linux e....miracolo!! Funziona tutto perfettamente. :-\
Boh

[blaze++]

Ti collegavi via cavo o wireless???

[webeco]

Cavo... >:(

p.s. su linea adsl

[webeco]

Da profano mi pare che il problema risieda nel fatto che non riesce ad acquisire l'IP 

[blaze++]

forse il problema sono i dns!
Prova ad eseguire un terminale e scrivere

Codice: Seleziona tutto

pppoeconf

segui le istruzioni (nel dubbio io davo sempre ok e non ho avuto problemi)
Fammi sapere

[webeco]

Allora,pare ci siano problemi. Alla fine dei test dice:

"Sorry, I scanned 3 interfaces, but the Access
Concentrator of your proveder did not respond. Please
check your network and modem cables. Another reason
for the scan failure may also be another running pppoe
process which controls the modem"

scusa eventuali errori ma l'ho dovuto ridigitare sul pc dal quale posto

[blaze++]

Prova così:
vai su Sistema--->Amministrazione--->Rete
Spunta la casella di connessione via cavo e clicca su proprietà
Abilita la modalità roaming e vedi se internet va.

Se non va (ov lentissimo), disabilita modalità roamig, seleziona configurazione automatica dhcp
e prova
se non va ancora, lasciando le ultime impostazioni, ridigita il comando pppoeconf

Fammi sapere!

[webeco]

Allora...
1) modalità roaming (che è quella di default) non va.
2) modalità DHCP già provata, non va.
3) anche seguendo la terza opzione..... non va  :-\

quel che mi da fastidio e che sul "misero" puppy....funge perfettamente 

[blaze++]

Allora non saprei...
Spero che qualcuno con un po' più di esperienza ti dia una mano!
Ciao

Ti ringrazio blaze, sei stato molto gentile

Piccolo aggiornamento. Ho visto che puppy linux crea un (o almeno penso che sia uno) file di configurazione di alcuni dispositivi compresi quelli di rete.
Posto per i più esperti che magari sono in grado di ricavarne delle impostazioni per fare andare la rete sotto ubuntu.
Ho visto che ci sono un paio di sezioni che riguardano il settaggio della rete, una piu' o meno all'inizio e l'altra alla fine del file.

#this file is included (inserted) in rc.local0
#setup the networking.
#note, analog modem dialup is configured after bootup,
by the
#Modem Wizard and Gkdial (or ppp).
#Ethernet network is configured after bootup, by the
Puppy Ethernet Wizard.

#note, "> out.txt 2>&1" is syntax required to redirect
both stdout and
#stderr to a file, using BusyBox Ash shell (not "&>").

interessante.. io su un vecchio pentium 3 ho provato a mettere debian minimale, ma non mi riconosceva la scheda di rete... proverò puppy linux anche se il nome nn mi sembra molto professionale 

[webeco]

Beh..il nome è indicativo del fatto che si tratta di un sistema leggero per macchine un po vecchiotte. Infatti l'ho installato su un vecchio notebook con un pentium 2 mi pare e 64mb di ram. Ma si tratta comunque di un sistema linux con tutti i programmi e tools di cui si può avere bisogno.
ciao.
