Issue

• 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...

Solution

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"
fi

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 "$comm" in
    dbus-daemon|dbus-launch)
        echo "Killing '$comm' (PID $pid) ..."
        kill $pid
        ;;
    esac
done

This is depressing to think about nonfree firmware eating the world:

Uncompressed source code of Linux 5.16.7: 1.1GB

The "source" of nonfree firmware: Over 700MB and growing so it's a good percentage of the size of the ENTIRE KERNEL ITSELF.

Free firmware with actual source code? 24.5MB and not growing

Hey folks! It's been a long time, but as usual we had to get everything just exactly perfect, and you just can't rush that. We are very happy to announce the availability of the new Slackware 15.0 stable release. There have been way too many changes to even begin to cover them here, but for our dedicated user base suffice to say that you'll find things modern but also familiar. We've gone ...

Cet article est un petit mémo sur la configuration de yum derrière un proxy.

Yum est le gestionnaire de paquets RPM utilisé sous Red Hat, CentOS ou encore Fedora.
Cependant, si la machine est dérrière un proxy Yum ne pourra pas accéder aux différents mirroires sur internet. Pour ce fair, il faut aller modifier son fichier de configuration yum.conf.
