Sto cercando di montare una sftp
connessione in una cartella utilizzando sshfs
il seguente comando che genera un errore.
~$ sshfs admin@example.com:/ testfo
remote host has disconnected
Lo stesso errore si verifica se I SSH nel sistema e ripeto il comando con localhost
. Questo comando ha funzionato anche con un'altra macchina, quindi il problema è da qualche parte sul server.
~$ cat /var/log/auth.log

La ~/.ssh
directory è di proprietà di admin da quando l'ho vista come un tentativo di debug per un problema simile.
Ulteriori informazioni per riferimento futuro:
Il problema non è con SSH stesso, ma con SFTP. Ciò si manifesta con il fatto che le connessioni SSH funzionano correttamente ma SFTP ha sempre esito negativo. Tentativo di risultati SFTP inReceived unexpected end-of-file from SFTP server
Il problema non è correlato alle stringhe di output degli script di accesso (ad es ~/.bashrc
.).
Il problema è presente da tutti gli utenti (incluso root).

il pacchetto è installato. ( sudo apt-get install openssh-sftp-server

Received unexpected end-of-file from SFTP server
sftp
a utenti diversi? 3) Come si presenta sshd_config
sul server? 4) Com'è il tuo ~/.bashrc
aspetto?
which sftp-server
. Sottosistema dovrebbe essere Subsystem sftp /usr/lib/openssh/sftp-server
. Hai sftp-server
installato? apt-get install openssh-sftp-server

sftp
direttamente? Qual è il contenuto di~/.bashrc
o altri file di avvio nella home directory del server?
