Re: ssh public key authentication problem using curl
Greetings, carolus! You didn't supplied a username to the remote host at all. Quite predictable, you got a name mismatch... Thanks. That was the clue. The following all work, connecting to my cygwin home directory on the server: ssh dell03 sftp dell03 lftp sftp://dell03 but curl requires a more explicit syntax: curl sftp://cdr@dell03 I had tried curl -u cdr, but that asks for a password. Since I want to use curl in a script, I did not want to have to enter a password. I did not think of trying a different syntax until reading your suggestion. Many tools take your $USER as login name to remote host by default. Which is a rather wild guess, in general, but often works... locally. -- WBR, Andrey Repin (anrdae...@freemail.ru) 10.11.2011, 05:06 Sorry for my terrible english... -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
Re: ssh public key authentication problem using curl
Greetings, carolus! What was exact command? curl -v -O sftp://dell03/cygdrive/f/transit_ext/this_is_external_drive.txt (without the newline. I can't get rid of it using the Thunderbird newsreader to write this reply.) And so, what the answer you've expected? You didn't supplied a username to the remote host at all.

Re: ssh public key authentication problem using curl
Greetings, carolus! After setup with ssh-host-config, ssh-user-config, and ssh-copy-id, public key authentication works with ssh but fails with curl. (Password authentication works with curl -u, but is less convenient.) curl -v shows: SSH authentication methods available: publickey,password,keyboard-interactive Using ssh public key file /home/cdr/.ssh/id_dsa.pub Using ssh private key file /home/cdr/.ssh/id_dsa SSH public key authentication failed: Username/PublicKey combination invalid Authentication failure What was exact command? However, ssh authenticates OK using RSA. ssh -v shows: Next authentication method: publickey Offering public key: /home/cdr/.ssh/id_rsa Server accepts key: pkalg ssh-rsa blen 279 read PEM private key done: type RSA Authentication succeeded (publickey). Again: What was exact command? -- WBR, Andrey Repin (anrdae...@freemail.ru) 03.11.2011, 19:51 Sorry for my terrible english... -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

Why does curl insist on using the DSA key, when ssh is quite happy with the RSA key? I tried appending the public DSA key from the client to known_hosts on the server, but that didn't change anything. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

Correction: What I did was to append id_dsa.pub from the client to authorized_keys on the server, and to delete known_hosts on the server in case there was a conflict with prior data. There was no change in the behavior of either ssh -v host or curl -v -O sftp://host/path;. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
