NAME
xauthority-hostname-updater - Daemon that keeps hostname in the Xauthority files up-to-date
SYNOPSIS
/usr/bin/xauthority-hostname-updater [OPTION...]
DESCRIPTION
xauthority-hostname-updater watches org.freedesktop.hostname1 for hostname changes, and update hostnames in Xauthority files for all active displays. When hostname is changed, xauthority-hostname-updater performs the following steps:
- Determines display names: uses $DISPLAY as the local display name and filter the /proc/net/tcp records by PORT > 6000 and real UID to identify remote displays
- Changes hostname in Xauthority files ($HOME/.Xauthority and $TMPDIR/xauth-$UID-_$DISPLAY) in records where:
- family of the record matches with the FamilyLocal (means non-network connection, usually UDS)
- hostname of the record matches with the previous hostname (the hostname before it was changed)
- display name of the record is contained in the list of display names generated at the 1st step
- •
- Remembers the hostname and sleeps for the next signal from the org.freedesktop.hostname1
