Hi Sean, Sorry, there is no error message in the server form the vsftpd service. Below you can find the information for both connections (with and without pam_exec), also add the information from the client, hope it help to fix this issue. Regards, António This is the log when pam is used for login without calling pam_exec: ** Server log Jun 20 11:01:03 cmdev vsftpd[12152]: pam_unix(vsftpd:session): session opened for user administrator by (uid=0) Jun 20 11:01:03 cmdev vsftpd[12152]: [administrator] OK LOGIN: Client "192.168.8.1" Jun 20 11:01:03 cmdev systemd-logind[552]: New session c85 of user administrator.

As it stands you have not provided enough information for a Debian contributor to investigate the problem. Could you provide a log including the error? Thanks. -- Saludos / Regards / Cumprimentos, António silva |
