It should be emptied ( unless you use OpenSuse, who don't bother with
all the clean-up service nonsense )
. . . but if it isn't cleaned out, then anything for that user should be
listed to ask about a re-connection.
Also I think he tried all this last time.

That's a good idea.
However, the logic tests for that in a loop . . . and automatically
increments
SESS_DISPLAY
# Check if there is already an agent running on that display on that host
let AGENT_DISPLAY=$SESS_DISPLAY+6000
if $COMMAND_NETCAT -z "$SERVER_HOST" $AGENT_DISPLAY 2>/dev/null
then
log 2 "Warning: Stray nxagent without .nX$SESS_DISPLAY-lock found
on host:port $SERVER_HOST:$AGENT_DISPLAY."
let SESS_DISPLAY=$SESS_DISPLAY+1
continue
fi
# Now check for the other enabled services
let SAMBA_DISPLAY=$SESS_DISPLAY+3000
if [ "$(getparam 'samba')" = 1 ] && $COMMAND_NETCAT -z "$SERVER_HOST"
$SAMBA_DISPLAY
then
log 2 "Warning: Skipping $SERVER_HOST:$AGENT_DISPLAY as samba port
is not free."
let SESS_DISPLAY=$SESS_DISPLAY+1
continue
fi
let MEDIA_DISPLAY=$SESS_DISPLAY+7000
if [ "$(getparam 'media')" = 1 ] && $COMMAND_NETCAT -z "$SERVER_HOST"
$MEDIA_DISPLAY
then
log 2 "Warning: Skipping $SERVER_HOST:$AGENT_DISPLAY as media port
is not free."
let SESS_DISPLAY=$SESS_DISPLAY+1
continue
fi
let CUPS_DISPLAY=$SESS_DISPLAY+9000
if [ "$(getparam 'cups')" = 1 ] && $COMMAND_NETCAT -z "$SERVER_HOST"
$CUPS_DISPLAY
then
log 2 "Warning: Skipping $SERVER_HOST:$AGENT_DISPLAY as cups port
is not free."
let SESS_DISPLAY=$SESS_DISPLAY+1
continue
fi
If it hasn't continued (round the loop again), then it breaks ( out of the
loop ) here

This comes from nxnode, so we've got quite a way along . . .

By line 1531 now it should have written . . . .
