I've setup a new proftpd server with mod_sftp for SSH support, that I'm able to login to when I use a password. But when I try to use my SSH key, I'm unable to connect.
Here's the full proftpd.conf file:
[root@myers log]# cat /usr/etc/proftpd.conf ServerName "Develop CENTS" ServerType standalone DefaultServer on Port 2215 UseIPv6 off # Umask 022 is a good standard umask to prevent new dirs and files # from being group and world writable. Umask 022 MaxInstances 15 User nobody Group nobody DefaultRoot ~ AllowOverwrite on # Bar use of SITE CHMOD by default <Limit SITE_CHMOD> DenyAll </Limit> <IfModule mod_auth_pam.c> AuthPAM off </IfModule> <IfModule mod_sftp.c> SFTPEngine on SFTPHostKey /usr/etc/proftpd/rsa_key SFTPHostKey /usr/etc/proftpd/dsa_key Port 2216 SFTPAuthMethods publickey MaxLoginAttempts 4 SFTPCompression delayed <VirtualHost www.mydomain.com> SFTPAuthorizedUserKeys file:/home/mydomain.com/.ssh/authorized_keys DefaultRoot ~ </VirtualHost> </IfModule>
Here's a line I see in /var/log/messages regardless of the authentication method used:
Mar 19 10:41:51 myers proftpd: myhost.com - unable to create namebind for 'www.mydomain.com' to IPAddress#21: No such file or directory
Other than that, the only thing appearing in the log file when I attempt to connect with a SSH key, is that the client does reach the server and a SSH2 session is opened, but the very next line indicates the SSH2 session is closed.
