Ubuntu – Why won’t Cyberduck connect via SFTP

sftpUbuntu

I'm receiving the following error when trying to connect via Cyberduck SFTP to an Ubuntu 9.10 server that I am able to successfully ssh into:

[main] ERROR ch.cyberduck.core.sftp.SFTPSession - Connection attempt canceled

I have other Ubuntu servers that I am able to successfully SSH into and Cyberduck is able to SFTP into. I've reviewed /etc/ssh/sshd_config and am now at a loss as to what else to check.

If your .bashrc or shell login is producing output sftp or scp will fail: FAQ. Try issuing a remote command via ssh:

ssh cookiemonster@myserver.com /bin/true

If the above spits out any text, you need to fix the offending text generator in the cookiemonster account's login scripts. No fortune cookies upon login for sftp. ;(

Ssh – SFTP – couldnt read packet: connection reset py peer

sorry i can't comment, so i have to answer directly.

the permissions with the build-in chroot system is a little bit tricky, i use the same method to create sftp only users:

part of my sshd_config:

Match group developers
    ChrootDirectory /home/%u/userdata

where %u matches every username here

assuming the following path

/home/developername/datadirectory/upload

permissions:

developername root:root rwxr-xr-x
datadirectory root:root rwxr-xr-x
upload developername:developers rwx------

if a user logs the directroy listing of / shows "upload"

SSH – cannot start sftp-server when trying to force internal sftp

Do you use "ChrootDirectory"? That would explain "file not found" if your "/usr/libexec/openssh/sftp-server" exist.

You should use "Subsystem sftp internal-sftp" instead (or give up on Chroot)
