DBUS_SESSION_BUS_ADDRESS enviroment variable is not set

[tomasvilda]

DBUS_SESSION_BUS_ADDRESS environment variable is not set on teleport session

What happened:

When logged to remote teleport host DBUS_SESSION_BUS_ADDRESS is not set in environment, because of that user systemd is not accessible

root@host:~# systemctl --user status
Failed to connect to bus: No such file or directory

What you expected to happen:

DBUS_SESSION_BUS_ADDRESS should be set as on usual login using terminal or ssh session.

For example for root session:

DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/0/bus

systemctl --user status command should return current status of systemd for user space

Reproduction Steps

1. Login to remote host using teleport
2. run command env
3. DBUS_SESSION_BUS_ADDRESS should be set

Does the permit_user_env option help here?

See:

• https://goteleport.com/docs/setup/reference/config/#teleportyaml
• Read user environment when creating child session #1020

No it doesn't help with this problem. Also enabled PAM, but that doesn't solve the problem. No XDG_* and DBUS env variables appear on teleport session.

I've just hit the same issue. It makes using systemctl out of the box a bit complicated
