Ho un'istanza EC2 in esecuzione. Posso ssh senza problemi:scp su Amazon EC2 non riesce ma ssh funziona

ssh -i mykey.pem [email protected] 

. Tuttavia, scp fallisce. L'esecuzione di questo:

scp -vvv -i mykey.pem test.txt [email protected]:/tmp/ 

produce il seguente risultato:

Executing: program /usr/bin/ssh host someIPadress, user ec2-user, command scp -v -t /tmp/ 
OpenSSH_6.0p1 Debian-3ubuntu1, OpenSSL 1.0.1c 10 May 2012

debug1: Connecting to someIPaddress [someIPaddress] port 22. 
debug1: connect to address someIPadress port 22: Network is unreachable 
ssh: connect to host someIPaddress port 22: Network is unreachable 
lost connection 

informazioni supplementari:

  • La mia chiave .pem ha permessi di lettura e scrittura solo per me stesso (-rw --- ----).

  • mi è stato detto che ci potrebbe essere un problema con SCP se in esecuzione/bin/true su EC2 produce una linea non vuota, ma questo non è il caso qui:

    [[email protected] ~]$ /bin/true 
    [[email protected] ~]$ 
    
  • ho verificato che esiste test.txt :)

  • Ho verificato di poter scrivere in/tmp effettuando l'accesso tramite ssh.

Sono sorpreso che ssh funzioni, ma non scp. Qualche idea?

Edit: corsa

ssh -vvv -i mykey.pem [email protected] 

produce:

Qual è l'output di debug per 'ssh -vvv'? – chepner

+0

L'output è lungo. L'ho aggiunto al test principale della mia domanda. –

+0

La cosa interessante è che sembra che 'ssh' non riesca inizialmente, ma ricade su un altro metodo che alla fine riesce. Temo di non poter diagnosticare oltre, ma forse qualcun altro può fornire assistenza. – chepner

Un'altra causa di questo problema (SCP non riuscendo dove SSH riesce) sta avendo alcun messaggio stampato sulla console durante il login (ad esempio dalla tua. bashrc sceneggiatura)

Ha funzionato per me, ho installato zsh sulla mia casella AWS Linux. Ma il comando 'chsh -s/bin/zsh' non ha funzionato quindi ho concatenato' zsh; 'alla fine del mio file' .bashrc'. Dopo aver rimosso il comando, lo scp ha funzionato. Ho usato 'chsh -s/bin/zsh ec2-user' come root per ottenere zsh come shell di default ora. Grazie. – OnethingSimple
