[Bug 459730] Re: rsyslog doesn't create /dev/xconsole

[Thomas Schweikle]

/dev/xconsole isn't created if it isn't there. If /dev/xconsole exists
it is not taken to output logs as given in
/etc/rsyslog.d/50-default.conf.

Creating /dev/xconsole and changing user:group doesn't help. service
rsyslog restart doesn't have access to this pipe. It doesn't matter if
apparmore is active or not. The reported error is in all cases the same:

Jun 13 15:25:59 nc158-muc rsyslogd-2039: Could no open output pipe '/dev/tty12': Permission denied [try http://www.rsyslog.com/e/2039 ]
Jun 13 15:25:59 nc158-muc rsyslogd-2039: Could no open output pipe '/dev/xconsole': No such file or directory [try http://www.rsyslog.com/e/2039 ]

# ls -la /dev/tty
crw--w---- 1 root tty 4, 12 Jun 13 15:18 /dev/tty12

/dev/xconsole is destroyed every reboot.

If xconsole is installed /dev/xconsole should be created and used by
rsyslog. If /dev/tty12 is configured to printout all logs it should be
used by rsyslog if at least groups match!

# grep syslog /etc/group
tty:x:5:syslog

# ps axu | grep syslog
syslog    5886  0.0  0.0 257916  1260 ?        Ssl  15:25   0:00 rsyslogd

Title:
  rsyslog doesn't create /dev/xconsole

Status in One Hundred Papercuts:
  Fix Released
Status in rsyslog package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: rsyslog

  Looks like this was missed in the move to upstart.

  This function was called in init.d/rsyslog start:

  create_xconsole() {
          if [ ! -e /dev/xconsole ]
          then
                  mknod -m 640 /dev/xconsole p
                  chown root:adm /dev/xconsole
                  [ -x /sbin/restorecon ] && /sbin/restorecon /dev/xconsole
          fi
  }

  I can't find any reference to it now. If this is old school then it should be re
  moved from the config.

  rsyslog:
    Installed: 4.2.0-2ubuntu5
