azz no! non funzionano. finalmente un indizio

Inoltre, ho scoperto un'altra cosa: ho creato una nuova virtualbox, sempre ubuntu, e da li questi comandi funzionano (rsync, scp, ssh, etc.) quindi direi di poter concludere che il problema è dentro la virtual maledetta box. Resta solo da capire dove

Aggiungo qualche altro elemento utile al debug.
Ho abilitato il verbose di ssh, questo è quello che accade:

ma sulla nuova VM hai installato ssh come l'altra? o con la password




p.s.
quindi il router non c'entra nulla... problema di autorizzazioni di rete?

Sulla nuova VM utilizzo la stessa identica chiave privata.
Il router in qualche modo c'entra, perchè se ricollego quello vecchio tutto rifunziona... credo che in qualche modo la questione abbia a che vedere con la coppia ubuntu+router nuovo

[sacarde]

con quello vecchio funziona?!

allora ha qualche configurazione strana lui?

[Gil Mour]

Si, come ho scritto in apertura di topic. Però lo schematizzo di nuovo.

Ci sono due vm, entrambe ubuntu, diciamo U1 e U2, e due router, diciamo R1 (il vecchio) e R2 (il nuovo).

- U1 + R1 -> tutto funziona
- U1 + R2 -> ping, ssh, name resolution funzionano, ma rsync su ssh no (non funziona neanche scp)
- U2 + R1 -> tutto funziona
- U2 + R2 -> tutto funziona

Quindi ci deve essere qualcosa nella configurazione di U1 che non va bene se accoppiata con R1.

[sacarde]

secondo me stride un po':

U1 + R2

ssh va e scp no.... non usano lo stesso protocollo? e l'autenticazione?

[Gil Mour]

l'autenticazione va
stavo pensando un'altra cosa: questo router nuovo, diversamente dal vecchio, supporta VOIP. E' possibile che ci sia qualcosa che richiede una diversa configurazione di rete in ubuntu?
Considerando che /etc/network/interfaces sono praticamente identici sia un U1 che in U2?

[sacarde]

che errore danno sftp e scp quando non funzionano ?
