| This page is a starting point for debugging kio_sftp. Please also read [[Development/Tutorials/Debugging/Debugging_IOSlaves|how to debug IO slaves generically]].
| | Moved to the [https://community.kde.org/Guidelines_and_HOWTOs/Debugging/Debugging_IOSlaves/Debugging_kio_sftp Community wiki]. |

| = Overview =
| |
| | |
| When you point file manager to sftp://''user''@''target'', [http://websvn.kde.org/trunk/KDE/kdebase/runtime/kioslave/sftp/kio_sftp.cpp?view=log the sftp kioslave] uses [http://www.libssh.org libssh] to open a connection to the sftp server.

| = Reporting Bugs =
| |
| | |
| If this is your first bug report please read the following document:
| |
| | |
| [http://www.chiark.greenend.org.uk/~sgtatham/bugs.html How to Report Bugs Effectively]
| |
| | |
| Then got to http://bugs.kde.org/ and create a bug report. Tell us:
| |
| | |
| * The KDE you're running
| |
| * The libssh version installed
| |
| * The sftp server version (e.g. the openssh version on the server)
| |
| * If you use ~/.ssh/config show us your special host config
| |
| * Provide log files if possible (see below)
| |
| | |
| = Logging =
| |
| | |
| You may want to switch on logging for kio_sftp.
| |
| | |
| In this example, we want to log the output to /tmp/kio_sftp.log. Open a konsole or run the command 'kdebugdialog --fullmode'.
| |
| | |
| In the "Debug Area" select "7120 kio_sftp". In the Information box select 'Information' as the "Output" and use '/tmp/kio_sftp.log' a the "File".
| |
| | |
| To enable logging you have to reload the slave system. You can do this by calling:
| |
| | |
| 'kdeinit4'
| |
| | |
| = Logging with libssh debut output =
| |
| | |
| To enable libssh debug messages in addition you have to set an environment variable before calling kdeinit.
| |
| | |
| KIO_SFTP_LOG_VERBOSITY=1 kdeinit4
| |
| | |
| = Enable logging in openssh =

| ==(Both of the instructions below refer to sshd, the server--these should not affect client operations, e.g. running ssh or sftp. I don't think these instructions are correct.)==
| |
| | |
| == SSH Logging ==
| |
| | |
| Edit /etc/ssh/sshd_config
| |
| | |
| Look for LogLevel and set it to:
| |
| | |
| LogLevel DEBUG
| |
| | |
| == SFTP Logging ==
| |
| | |
| Edit /etc/ssh/sshd_config
| |
| | |
| Look for the sftp subsystem and change it to:
| |
| | |
| Subsystem sftp /usr/lib64/ssh/sftp-server -l DEBUG
| |
