Ubuntu :: Queue - Prevent From Starting Automatically Upon Logging In?

May 8, 2010

I have a couple apps that I cannot figure out how to prevent them from starting automatically upon logging in. They are NOT listed in my Startup Applications under preferences. For example, pidgin. Pidgin automatically starts at each login even though it is not in the startup apps nor can I find an option in pidgin itself. Tomboy is another. I always get an error that tomboy cannot be added to my panel when I restart. The error in the tomboy panel log is that tomboy is already running. Does ubuntu have a hidden "start up" folder like Windows does in the start menu? Where can I clear this file/folder?

Ubuntu Networking :: Prevent Apache2 Server From Starting At Boot?

Nov 18, 2010

One of my ubuntu 10.04 boxes starts apache2 server automatically at boot. I know from the output of the command:


sudo /etc/init.d/apache2 status

I can't remember even setting that up, and I don't think it does so by default, since my other box in fact does not even have apache2 server installed. I can stop the server once I login, but is there a way to stop it from automatically starting the server, or even better, completely uninstall the daemon. I tried


sudo apt-get remove apache2

but that does not work. I guess the daemon is part of some bigger package.

Server :: Ssh: Prevent Disconnection After A Command?

Aug 19, 2010

I wish to create aliases to log into a server and go to a specific folder. For example, I have two aliases:


alias REP1='ssh me@server cd /REP1'
alias REP2='ssh me@server cd /REP2'

and of course, I'm disconnected after cd commands. I found no ssh option which prevents this disconnection to occur. I also tried the following trick:


ssh me@server "cd /REP; bash -i"

but it left me with a crappy shell (no color, directions keys printing ^]]A, ...)

Ubuntu Security :: How To Prevent Grub Command-line Boots

May 18, 2011

The ability to manually boot using the Grub command-line constitutes a big security risk in Linux, IMO.Any OS can be booted in this manner from a PXE-LAN, USB, or CD/DVD drive, circumventing BIOS-imposed boot restrictions. (Once a foreign OS is booted, of course, it can be used to access any part of an unencrypted hard drive.) Placing passwords or locking menu items (in the Grub configuration files) does not prevent a user from booting manually using commands entered at the grub command-line.

As it stands now, when presented with the Grub menu (or after bringing up a hidden Grub menu with the "ESC" key), a user only needs to hit "c" to enter the Grub command-line mode to facilitate any type of bootup whatsoever. (They can then enter manually the Grub commands to boot an OS on any device.) This is extremely insecure and allows any passerby to boot the computer with a few keystrokes and a bootable USB drive. How do I configure Grub so that it will require a password in order to enter the command-line mode (and thereby restrict boot options to the menu, which can then be password protected/locked) ?

Ubuntu :: Prevent System Freeze Due To High RAM Or CPU Usage

May 1, 2011

I have been using ubuntu for 4 years now on my decent laptop with 2 Gb RAM, dual core centrino, etc etc. Yet, in all those years I have been using this superior OS, I still have to do hard shutdowns because some program runs wild. I have lately 2 scenarios where I have to interfere with the process:

1: amarok crashes and leaves the python script for the gnome shortcut keys running at 100% CPU. Or: thunderbird-bin keeps running after apparently clean close of Thunderbird. That's not really bothering me, I just kill both processes.

The bigger problem is scenario 2: 2: VLC starts eating all my RAM (for no reason), my SWAP starts filling and my computer becomes unusable for 10 minutes. Or: my matlab script is too big and eats up too much RAM -> same. Note: I have nothing against SWAP because at many other times it's very useful

These are stupid and annoying problems where there is an easy solution:

1) automatically kill the stupid process that runs at 100% CPU
2) automatically kill the stupid process that eats up all my RAM

OpenSUSE :: Prevent Web Browsers From Using The System's Default Colors?

Aug 1, 2009

I have two problems related to color scheme. First, is there any way to prevent web browsers from using the system's default colors? I use a dark scheme, specifically Obsidian Coast in KDE and Industrial in GTK. This doesn't behave well on web pages in Firefox, Arora, and Konqueror. (Opera is fine.) Sometimes a site's stylesheet will specify a text field's text color to be black, but its background is not specified, so it defaults to black-on-dark-gray. I've also seen such a field's background color specified as white while the text color was not, so it ended up being light-gray-on-white. Is there any way to keep browsers from ruining web pages? Also, even if the stylesheet doesn't specify the colors, the dark text fields and buttons still stick out like a sore thumb on a warm or bright page.

My second problem is this: I have a saved session that brings up my applications every time I log in, but the GTK apps Pidgin and Evolution don't match the GTK color scheme until I quit and start them up again. Is there some way of fixing or working around this problem?

Ubuntu Security :: Prevent Fork Bombs From Bringing The System To Grinding Halt?

Mar 18, 2011

So I am basically just curious about this, but is there a way to prevent fork bombs from bringing the system to grinding halt in Ubuntu, without setting hard limits on the resources available to users? I read about fork bombs on Wikipedia, and being the masochist I am (and not having any unsaved work), I tried entering those 13 characters into terminal. Wow. I have never seen a computer freeze up so fast.What really peaked my curiosity is that the same fork bomb has almost no effect on the performance of Mac OSX (10.6). I know that one can limit the availability of resources to specific users. Is that essentially what Snow Leopard is doing?

Slackware :: Prevent File System Corruption On Hard Lock-up?

Apr 5, 2010

I've recently had my file system irrecoverably corrupted after a hard lock-up. This has happened to me before, a couple weeks ago, and both times I've had to reinstall. I don't know what is causing the lock-ups (possibly the binary nvidia driver..), but I would like my file system to be intact or at least recoverable next time it happens.What is the "safest" way to mount things?

I'll be using ext3 with data=journal, but I've read that disk write caching combined with a kernel crash or power loss can still screw things up. Supposedly, mounting with barrier=1 helps some, but doesn't work with LVM? Would it be wise to turn off disk write caching completely? I understand there's a performance penalty, but if it helps keep the file system consistent in case of disaster.

Ubuntu :: Starting App Command Not Working Correctly?

Jan 2, 2011

why this command:

/usr/bin/freepopsd -vv > /home/shocker/Desktop/Freepopsd.log

doesn't write the log in the Desktop folder? It's written exactly like that in the Ubuntu startup program control panel and according to the ps command I understand it's correctly running:

$ ps aux | grep freepopsd
shocker 1676 0.0 0.1 227264 9128 ? S 13:22 0:00 /usr/bin/freepopsd -vv > /home/shocker/Desktop/Freepopsd.log
