  • When processes needing dbus are launched remotely (via ssh, LSF, or a similar tool), dbus processes keep running even after the main process is closed, blocking the remote session and preven...


For interactive use, make sure to launch dbus-run-session before the shell. For instance, add this to .bashrc:

if test -z "$DBUS_SESSION_BUS_ADDRESS" ; then
  exec dbus-run-session -- bash
  echo "D-Bus per-session daemon address is: $DBUS_SESSION_BUS_ADDRESS"

Write bash_logout script which will be in charge of killing remaining dbus-* programs for the session, assuming it's the last bash

# ~/.bash_logout

# Check if we are the "parent" shell in a ssh session
[ "$(cat /proc/$PPID/comm)" == "sshd" ] || return

cgroup=$(awk -F ':' '$2 == "name=systemd" { print $3 }' /proc/self/cgroup)
[ -n "$cgroup" ] || return

# Search for "dbus-[daemon|launch]" programs running for this session

for pid in $(cat /sys/fs/cgroup/systemd/$cgroup/tasks 2>/dev/null); do
    comm=$(cat /proc/$pid/comm 2>/dev/null)
    case "$comm" in
        echo "Killing '$comm' (PID $pid) ..."
        kill $pid
