Hello, I'm re-submitting this question, as my previous attempt had formatting issues.
I’m deploying guacamole on docker containers on Linux, and I’ve noticed that when I leave an SSH session idle for about 10 minutes (perhaps slightly less), any SFTP action fails. For example, when I try to view files in a directory (say /home), I get the error "Unable to read file /home” in the `guacd` logs, and the result is just an empty list of files in the file browser. After looking at the code, it seems this error occurs when the `libssh2_sftp_open` returns NULL, and according to the docs at https://www.libssh2.org/libssh2_sftp_open_ex.html";>https://www.libssh2.org/libssh2_sftp_open_ex.html NULL is returned “on failure”. Note that the SSH session is still very functional and working when the SFTP session fails to respond. When I reconnect the session, SFTP works fine. I suspect this might be due to lack of SFTP keep-alives, but I could not find any guacamole configuration to allow this. I did attempt using the ssh-keep-alive I’m using the dockerhub images of guacd and guacamole, tagged 1.3.0. I would appreciate any help/guidance on this, currently I’m just trying to figure out if this is a problem with my setup of guacamole or just a bug Thanks!
