9.10 aiuto!

[MimìElia]

ciao mi appello alle vostre esperienze perchè sto veramente esaurendo da mesi!
ho un pavillon hp e ho 9.10 come s.o.
tutto sembra apposto , ma in realtà ho problemi vari riguardante gli aggiornamenti e la wireless.
Il fatto che internet non apra tutte le pagine è una conseguenza degli aggiornamenti non fatti ???
vi prego mi si aprono le pagine a metà e quelle di wikipedia e dei social network mi sogno di visualizzarle! >:( >:( >:( >

che modem/router usi per navigare, quello di alice?

[MimìElia]

si... ::)
ho chiamato 2 volte il 187  e mi hann detto che la linea va bene ... in effetti va bene , perciò il problemaq è tutto "ubuntiano"

[ethyl]

fai questa prova

Codice: Seleziona tutto

sudo gedit /etc/sysctl.conf

e aggiungi e/o modifica

net.ipv4.tcp_syncookies=1
net.ipv4.tcp_window_scaling=0
net.ipv4.tcp_ecn=0

al file, poi salva e chiudi. Vedi se cambia qualcosa

[MimìElia]

command not found ::)

[MimìElia]

nooo aspetta ethyl.... :-[

[ethyl]

hai ubuntu o kubuntu??
nel caso fosse kubuntu ridai il comando sostituendo gedit con kate

[MimìElia]

dice prima della stringa net.ipv4.tcp  che:

uncomment the next line to enable TCP/IP SYN coockies
this disables tcp window scaling(http://lkml.org/lkml/2008/2/5/167)
and iss not recommended

cosa da fastidio?

[ethyl]

lascia stare i commenti.....
basta copiare quelle tre stringhe in fondo al file , verifica comunque che non esista una riga identica senza il commento avanti ( il commento è questo # ), se c'è cambia/verifica  solo il valore ( 0 o 1 ).

[MimìElia]

non cambia nulla ... purtroppo...
e cmq credo di aver copiato correttamente mettendo quello che hai detto tu senza il cancelletto...
sn una frana ? ???

[ethyl]

per sicurezza posta il contenuto di sysctl.conf

Codice: Seleziona tutto

cat /etc/sysctl.conf

[MimìElia]

dice kernel.maps_protect=1

[ethyl]

mmhh
il file sysctl.conf dovrebbe essere qualcosa del genere

Codice: Seleziona tutto

bastava solo aggiungere 3 righe.......

[MimìElia]

e io l ho fatto...

[ethyl]

da quello che hai postato il file ha solo  questa riga:
kernel.maps_protect=1

prova ad aprirlo con gedit e vedi se è completo ( come quando lo hai aperto la prima volta ).
