Ciao a tutti, scusate se rompo un po' troppo...però sembra che i problemi saltino fuori tutti allo stesso momento 
ALlora pingando un sito internet ho il seguente output:
| Code: |
PING www.gentoo.org (195.66.242.4): 56 octets data
64 octets from 195.66.242.4: icmp_seq=0 ttl=57 time=879.3 ms

eccetera eccetera...
Se però faccio un ping all'altro pc in locale, il ping funziona correttamente senza errori strani.
Chiamo un esorcista??
Grazie mille

Sembra esserci qc problema quando il delay aumenta a dismisura.
Voglio dire un time di 1 sec e' eccessivo...  Che connessione hai?
Cosa c'e' tra te e gentoo.org?

Tra me e internet c'é l'altro pc che fa da gateway. Il fatto é che fino a qualche giorno fa il ping funzionava, e anche adesso un po' va un po' non va.
Oh grande saggio cosa suggerisci per il mio umile problema? 
Grazie mille ancora!

Ma non sembra che il ping non vada, e' solo che quando il delay aumenta, anche la possibilia' che il pacchetto si rovini segue la statistica 
Piu' che altro, sembra che sia un problema di linea (hai adsl?).
Prova a cambiare l'mtu (abbassarlo) e/o a diminuire il packet size.
Infine, che versione di ppp hai?

Grazie mille Cerri, ho un ADSL 256 / 64

Cercando in internet ho visto che dovrei mettere in uno script d'avvio una riga con ifconfig eth0..... il fatto é che nn so che valori mettere per l'mtu e per il packet size, mi potresti consigliare.
La versione di ppp é la 2.4.1 |

Allora, per l'mtu fai | Code: | | # ifconfig $INTERFACCIAPPP mtu 512 |
Se fosse questo, lamentati perche' l'MTU standard e' 1500 e' deve essere questo.
Qual'e' l'output del comando ?

Fai lo stesso test di ping con i seguenti host:
| Code: | 1 adslplus.zur01a02.sunrise.ch
2 f5-21.zur01s10.sunrise.ch
3 g5-1.zur01b03.sunrise.ch
4 srp12-0-0.zur14s03.sunrise.ch |

Pinga gli indirizzi ip degli altri host g5-1.zur01b03.sunrise.ch e srp12-0-0.zur14s03.sunrise.ch .
Queste prove devono essere effettuate quando hai quell'errore che accennavi all'inzio del post.

Io ho provato, sia quando dà l'errore, sia quando non lo da. Però il ping da sempre "unknown host".
Grazie mille.

Non ci siamo capiti.
Al posto di g5-1.zur01b03.sunrise.ch utilizza 193.192.234.197 e al posto di srp12-0-0.zur14s03.sunrise.ch utilizza 193.192.227.57.
Quello che sto cercando di capire e' se il problema dei pacchetti rovinati e' conseguenza di un host della rete del tuo provider (SunRise?) oppure no.

Qui risulta tutto ok.
Ma ora hai ancora problemi di ping "strani"???

Il fatto é che i problemi ci sono spesso. Ma i tempi così lunghi di risposta al ping sono giusti?

L'ultimo test che puoi fare e' questo:
| Code: | | # ping 213.242.67.21 |
Perche' e' l'ultimo "host" attaccato alla rete del tuo provider.
Sinceramente i tempi di risposta sono esagerati, anche per un'adsl, ma mi da l'idea di uno shaping da qualche parte un po' sovraccarico... che comunque non giustifica il ping "rovinato".

Ecco fatto.
