Slackware :: Screensaver Password Not Being Asked For
Jul 19, 2009Slackware64, 13.1, Xfce: Sreensaver is configured to Lock Screen After 5 minutes. This works fine. My problem is that 90% of the time, when I go to wake the screensaver, it won't ask for a password and won't come out of screensaver. The only reliable method I have for getting the password prompt is to switch to a console and then switch back to the X session. Then, the screen saver doesn't display, it just asks for a password.
If I move the mouse when the screensaver is active, the screensaver animation freezes for ~20s and then resumes. If I touch a key (Esc, Shift, space, Enter), the animation freezes for ~30s and then resumes. I never see the Enter Password dialog. Screensaver is configured for Random. I haven't reliably gotten it to work often enough to offer any info as to when it works, but it has worked a couple of times. Keyboard and mouse are configured properly (HAL reports "Logitech Logitech USB Keyboard" for my Logitech Elite keyboard and X uses xkbrules evdev; the mouse is an MX Laser, identified as "Macintosh mouse button emulation").

Ubuntu :: Install WINE Screensaver In Gnome-screensaver Possible?
May 19, 2010There's an OSS screensaver on windows that I love called PixelCity (links:blog post, github). it's pretty cool. and it runs fine on my Ubuntu (Karmic 9.10) with wine.Is there a way I can tell the gnome-screensaver about it so I can use it as one of my screensavers? I'm still fairly new to Gnome and the whole "screensavers as themes" thing is still confusing me.I've found my themesdir and tried to create a .desktop file for it, but obviously I've gotten something wrong as it just doesn't show when I open the screensaver prefs dialog, no error, no message, it's just not there.
Installing the xscreensaver packages added the extra screensavers I was missing, and I'm a pixelcity away from perfection..Of course the perfect solution would be if someone ported the screensaver natively to linux, which shouldn't be too hard as the source is open, it already runs on openGL and tries to confine most windows stuff to a single file. But I don't know C++ or 3D code or win/linux internals so I wouldn't know where to start..
General :: Setting Setuid Without Execute Bit?
Jan 24, 2010setuid bit allows the process to execute the file with the uid of the file. But, what is the purpose of setting setuid without execute bit? The man page tells that if a file is setuid without execute flag, the permission will be displayed as 'S' (capital s) in ls command. Why should anyone set the setuid without execute flag? Does setting setuid without execute flag have any special meaning?
View 1 Replies View RelatedProgramming :: SetUID On Different PID Or Child Process
Aug 18, 2010I have a root process (on linux) that forks a child and the child process then drops privileges by doing a setuid() to a normal user. After the child setuid()'s, it is of course impossible for it to gain root again by itself. But since the main process is still running as root, i was wondering if there was a simple/smart way of getting the root-master-process to elevate the child back to root (or maybe just to another non-privi uid). Is there some way to do a setuid() on another pid? or maybe something can be done through /proc/<pid>/? Killing the child is not an option (because its what it does today and im trying to find a smarter way). (The program is apache2's mpm-itk worker and the "child" is the actual apache2 process serving a page.)

View 3 Replies View RelatedGeneral :: Setuid Process Cannot See Processes Owned By That User
Nov 2, 2010I would like to give a non-root user (nicollet) the ability to detect and send a signal to processes started by Apache2 (those processes are FastCGI scripts and the signal tells them to empty their cache). The processes are owned by the web user (www-data), and I'm running on Debian unstable.
I can't find any way to have the nicollet user see those processes.
The processes are running and can see by both root and www-data:
root@linux-01:~# ps -Af | grep baryton
www-data 17649 17648 0 10:27 ? 00:00:00 baryton
www-data 28145 1 0 Nov01 ? 00:00:12 baryton --bot
root 18701 18700 0 10:46 pts/0 00:00:00 grep baryton
root@linux-01:~#
[Code]....
The most surprising is that the grep process is indeed run by www-data (because it's started from a setuid executable) and is visible, but the baryton process isn't.
What's going on here? Why can ps run by www-data show those processes, but ps run by a setuid executable running as www-data cannot, when it's started by nicollet?
Security :: "Outbound" Messages And Checksecurity.log Setuid Changes
Aug 11, 2010I am using ubuntu 10.04 on an iMac 7.1. What do the following log entries mean? I recently had a "sbin/init infected" alarm with chkrootkit (or rkhunter, I forget which) and reinstalled, and I thought I was rid of the problem, whatever it was (could have been a kernel panic), but now the checksecurity setuid stuff reappeared (the checksecurity.log only appears in the log file viewer after resetting it with gconftool-2 --recursive-unset /apps/gnome-system-log, which seems suspicious; why is the log hidden by default?); also there are "outbound" messages that I don't understand. I have another ubuntu install on another Mac which seems to be unaffected (and also has checksecurity installed; I just ran it manually and also got setuid stuff, but there is no "outbound" and ufw.log is empty). I can't really think I have a rootkit (I don't notice any effects except these anomalous logfiles, and my browsing habits don't include sleazy websites). And what exactly are bound sockets? There is a lot of information about sockets on the net but it's all rather technical. I continue to look of course. I ran chkrootkit and rkhunter again, and they read clean (if I can trust them).
Is it possible that the trouble is related to the Mac's BIOS emulation? (Apple does not seem to take security very seriously; Snow Leopard does not even ask for a password for Software Update - I asked my premium reseller and he confirmed it. I should not be surprised to find out that the iMac's BIOS emulation is unsafe. I'll need to get a real computer). The MacBook Pro 5.1 has a newer firmware (for instance, it will boot ubuntu from external disks which the iMac will not), and as I said that install seems to be unaffected (The setuid stuff is probably normal, but I'm not sure the "outbound" messages are). I use grub legacy, which seems to install to the Mac's EFI partition as /dev/sda (GParted shows 18.1 MB of 200MB used on both computers with ubuntu on them, whereas an HFS+ disk without ubuntu, or with GRUB in a partition, will show 3.09 MB used).
Does it make sense to reconfigure checksecurity to check for setuid changes daily (change CHECK_WEEKLY="SETUID" in /etc/checksecurity.conf to CHECK_DAILY="SETUID")?
checksecurity.log:
messages (part):
There also was a lot of terminal output similar to the iMac's which I forgot to save, and when I ran checksecurity again it was blank. (Incidentally, the list of setuid programs on Mac OS is a lot longer)

Jun 7, 2010I have recently upgraded from 9.10 to 10.04, and I have the following problem.My computer is set up to start the screensaver and lock the screen after 5 minutes of inactivity and to use a blank screen after 15. Whenever I come back after some moments of inactivity and move the mouse, the screensaver doesn't go away. Instead of having a box whereinput a password, I'm left with a still image of one frame of the screensaver. I can still input the password and press enter to unlock the screen, but it is a bit annoying nevertheless. Moreover this does not happen if the screen is blank: in that case I see the expected box.
View 2 Replies View RelatedDebian :: Screensaver Goes On When It Is Disabled
Aug 26, 2011I have this strange problem with screensaver (in fact i dont know if it is the problem, but it seems to be), i describe the problem next:I have a computer with debian squeeze installed. I use this computer only as a dumb terminal for showing information about companies, this means that it have no mouse nor keyboard connected to it. I configure autologin for a not-provileged user and autorun one app.
I disabled the screen saver for obvious reasons. This all works very fine. The problem is that when connect to the computer with ssh and reboot it, 10 minutes after started the monitor goes dark, as if the screensaver gets activated, then i connect a mouse and do some moves the screen goes to the normal functional state, then disconnect the mouse and it never goes dark again, after 1 day even!. When i turn on the computer with mouse and keyboard connected, just 20 seconds after started i disconnect those both, it do the same (after 10 minutes goes dark), but if wait for 1 minute usgin the mouse and keyboard and then disconnect both, the screen goes dark thing never came out. It just appear to happen at some point when the system does not detect any input.
