SFTP transfers in LXD container


(Del) #1

I have an Ubuntu 16.04 host with Ubuntu 16.04 container. I’m using SFTP jail (internal-sftp functionality) for transferring files. When I’m trying to detect partial uploaded files, by using fuser command, fuser doesn’t report any PIDs ( expected behaviour is to show SFTP PID during file upload). Strange thing is that this is an issue only with SFTP transfers , for example SCP transfers doesn’t have this issue. I will appreciate any ideas of why this is happening and eventually how to be fixed.


(Del) #2

I’m suspecting that apparmor prevents fuser to get information about SFTP process. Is there any way to disable apparmor for a certain container?

I believe its:

lxc config set <containername> raw.lxc lxc.aa_profile=unconfined
lxc restart <containername>

I don’t have an example lying around but I had to do that for a project awhile but, however those commands ended up not working and I instead had to make a new profile with them set and then create the container off that profile.
