I've only ever installed two programs that came in .tar.gz's with their own install.sh scripts. Each one recommended to be saved in /opt.What is opt? Should all .tar.gz programs with their script installer be handled in the opt directory?
View 6 RepliesI have the following scenario:
- Server installed in wired network. The server has a static IP. It has Ubuntu Server 9.10 installed.
- I have two Ubuntu notebooks (Ubuntu Desktop 9.10) and I want them to connect (mount) to the server on bootup (fstab or equal) if the network is available.
- I don't want to store the password in cleartext in the fstab file. So what other options do I have? What would be the most common practice here?
Description of problem:
I try to install ncl-5.1.1-3.el5.x86_64.rpm.
Missing Dependency: ncl-common = 5.1.1-3.el5 is needed by package ncl-5.1.1-3.el5.x86_64 (/ncl-5.1.1-3.el5.x86_64)
I try to install ncl-common-5.1.1-3.el5.x86_64.rpm
Missing Dependency: ncl = 5.1.1-3.el5 is needed by package ncl-common-5.1.1-3.el5.x86_64 (/ncl-common-5.1.1-3.el5.x86_64)

I'm just slightly confused here, but... what the? Why does installing grub-doc remove BOTH grub-pc, and grub-common? So basically it seems like by installing grub-doc, I have uninstalled grub totally (yes, it is still there as the bootloader, but i have no way of updating it now!) from my system. What's the conflict between grub-doc and grub-pc, such that grub-pc has to be removed?

I'm writing you to ask some help with administrating a server remotely.
I have a machine I use remotely when I have to travel, some time for quite long periods like from one to three months.
Last time it happened to me that after upgrading I send the reboot command
and the machine didn't turn down, so I couldn't be able to access it.
My question is: how can I avoid such situations?
Is there any best practice to follow?

View 12 Replies View RelatedRecently I've been going over a few resources (like Guide to the Secure Configuration of Red Hat Enterprise Linux 5) some forum members have provided and I've been using other resources I use for work (like the UNIX STIG requirements). I would like to improve my skill-set on hardening a linux server (for work and personal interest). Is there a specific linux distro I can install that is purposely corrupted/vulnerable where the sole goal is to secure it, and then have the means to scan it to make sure all vulnerabilities are patched and secured?
View 6 Replies View RelatedAm investigating processor affinity theory and practice, am somewhat surprised at the paucity of information on something that has been a part of many Windows Enterprise type applications for more than a decade and although I haven't investigated would assume is supported by big iron UNIX.What it is Processor Affinity is the *NIX terminology for "soft" assigning a process and its threads to a specific processor core. On multi-tasking machines and particularly those which run heavy loads it can be useful to "advise" the Scheduler to isolate/assign heavy loads to a core separate from other processes. I also have a specific situation where I would like to run more than one instance of a specific app, but cannot when sharing the same processing environment.
What I've found so far By default, any and all processes are assigned an affinity that permits running on any and all available processors.The taskset utility can be used to modify the affinity for any process, which means that once an application/service/process has been launched, only then can the affinity be modified.It seems that the RH platform may also have a utility called tuna which might provide some tuning capabilities in addition to setting affinity but does not seem to be in the SuSE repositories and I cannot find source.Is there a reference or utility that can launch an application with a specified processor affinity?
I was about to post a new thread and saw that there are several answers out here already and I have done the new group permission one on my server -- actually on my test server I just added "my user" to the group "root" to gain rw access to /var/www/htdocs/.Someone suggested that the proper way might be to do symlinks to the directory in a real production environment and I wanted to find out if that is the *best* way to go or whether to actually make a group "www_admin" (pick your favorite flavor of this) and add my users to that group?
I guess I am looking for the "best practice" in a real corporate production environment that is most secure.
I am new to Slackware but I'm a bit familiar with Ubuntu. I normally partition my ubuntu using /swap, /root and /home. In ubuntu it is recommended to separate /home and /root partitions so that later on if something to be changed in the system we just need to apply on that /root without affecting our old data in /home. Is it the same way in Slackware applied? If so, is it the same as having /swap, /root and /home partitions as well? Can anyone suggest for the harddisk distribution of my 320GB space..

For instance, the system is already broken with what is mentioned in the question so that I can focus only on solving the problem rather than breaking it first.

This guide isn't going to be updated anymore, as there is gNatty, and I've switched to Lubuntu. The reason? GDM kept crashing and issues kept coming up that reduced the overall functionality of my own computer. The PPA seems like it changes slightly to where things may break, if something does break, try to run: sudo apt-get install gnome-shell gnome-session again, as it looks like a lot of the time gnome-shell and gnome-session aren't being installed. FIX for issue opening certain applications (like games) Do the following in terminal:
Code:
echo "PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"" | tee -a ~/.profile Logout and log back in and that should fix the issue. NOTE: You have to do this for each user that logs into the system if they can't access games or that. FIX for .ICEauthority issue! There's another method besides this one, and it involves just installing the following:

View 1 Replies View RelatedI was looking for a converter to use on common avi files and maybe some others and came across this thread. I followed it all the way to where it asks me to install ConvertIt by adding the repos and then running Synaptic. I found convertit and marked for install and clicked apply and got this error:
Code:
convertit:
Depends: gambas2-runtime (<2.1) but 2.13.1-1ubuntu1 is to be installed
Depends: gambas2-gb-qt (<2.1) but 2.13.1-1ubuntu1 is to be installed
So i check synaptic for that and i had them installed already from the guide. So i marked them all for reinstall since i installed them in the terminal the first time. Reinstalled and i still get the same error.
Any idea whats wrong? Or is there a better movie converter thats easier? I just want to re encode the files so the will play on my 360.

I am running a fresh install of Lucid 64bit with Desktop effects enabled and the latest driver from Nvidia 195.36.24 (but had the problem also with the ubuntu repo driver. The issue can be reproduced as follows. Set AWN to group common windows (I believe this is the default) Open several gedit windows (or any other app) Then open firefox and maximize the window (or simply move the window so it's directly above your gedit dock icon.) In the AWN dock, select the gedit icon and try and select an open gedit window. When you click the gedit icon in the AWN dock, you'll see a popup with all of your gedit windows. If you move the mouse to attempt and select one of the gedit's, the menu disappears and you can't select anything.

i have been trying to figure out how to get my CAC working on my laptop so i can log into service portal sites and do things while i am TDY that require CAC logins. I have followed this tutorial [URL], and i got as far as getting the module installed into firefox, but it wouldnt aknowledge my card being inserted and wouldnt prompt me to select a certificate or anything. Then i tried OpenSC, but for one it wouldnt acknowldege my card being inserted and the module wouldnt load in firefox.
I mainly want to use this for logging into AirForce Portal, DTS, and Webmail while im TDY so i dont have to find a GOV computer to do that stuff on. I would ultimately like to get it setup to where i can use my CAC to login to my laptop just like a Government computer, but if i cant do that right now i wont cry over it.
Im using a SCM SCR3340, i havent seen it on any supported hardware list yet, but so far coolkey and opensc have both detected my reader, just opensc didnt detect my card being inserted.
