I have a machine that I want to install Nessus on it.
Nessus supports many Operating Systems:
Microsoft Windows
Mac OS X
Linux
FreeBSD
The full list is here: [URL]... What would the best OS to install Nessus on for performance be?
i want to install Nessus gui by using yum .HOw to Play with it .i want to conduct
Vulnerability assessments on the victim machine/ip.Can we use it for online scaning.if yes ?then how to perform ?
I successfully installed the nessus. It was .deb file . first of all, I type
"sudo dpkg -i Nessus-4.2.2-ubuntu910_amd64.deb".
The output of this command was "You can start nessusd by typing /etc/init.d/nessusd start"
That's why I type that command and I get " $Starting Nessus : ." There is nothing like interface of this software, when I try to search GUI from synaptic package manager. So What should I do ?
I just wanted to know if having my laptop set to ondemand, will this affect performance in any way? I realize it increases the clock speed to performance when the CPU is under load, but does the time it take to go from ondemand to performance affect speed? Will there be any noticeable difference between the two setups? I have a dual core intel at 2.2GHz when in performance. When ondemand is set with no load it downclocks to 800Mhz.

sudo apt-get install nessus
I get a message that the package is not available and anther package replace it. However I am interested in nessus and not in openvas-client (the other package). So how can I get the nessus package.
Whether NessusCleint and Nessus Server are available as two different packages or they have been merged into a single package.
Earlier there used to be 2 diff packages one for Nessus Cleint and other for Server. But now i was not abel to find any package for clinet and in the only package thats available on nessus.org also does not contain any cleint in it.
I have a backtrack distro on a usb stick. I wish to do the following :-
(a) Partition the usb stick to have a ext3 filesystem, so that the instln may be persistent for the changes. But the fdisk utility creates partitions as dev/sdb1p1 and /dev/sdb1p2. These however, could not be accessed by mkfs utility. How to overcome this problem.
(b) Next , I downloaded the nessus .lzm file and put it in the /base/module dir. But unable to start the nessus daemon. It suggests an error regarding unable to create /opt/nessus and /etc/nessus/nessusd.conf. I think starting nessus as root would help but the problem persists!
I am using nessus to evaluate the security of a web server. I have started up the nessus daemon on the server, here's the netstat output:

It's listening on the default nessus port 9390. I am trying to connect to the nessus server instance using Open-VAS Client. I have generated the client and server certificates, I have pointed the client at the User Certificate File, the User Key File and I have a CA cert. I have created a user account on the nessus server. The problem is that when I try and log in from the Open-VAS client it keeps saying it can't connect. Is there anywhere I can check to see if it's being caught in a firewall, or where I can see if the connection is even making it to the server..
I am using nessus 4.2.2. When running with command line:
nessus -q -x -T html 127.0.0.1 1241 myUser myPassword listTarget.txt output.txt
1241 is default port of nessus
The error throw out:
nessus : Could not open a connection to 127.0.0.1
But when I running nessus GUI by browser with localhost on port 8834 is ok.
Fedora 12
Nessus: 2.2.11-5
Authent: using passwrd
Client: GTK version
User: added with no rules
nessus-mkcrt: has been ran
Hosts.allow: hole made for localhost to nessusd with nessusd:127.0.0.1 (this took care of my ssl error)
Upon trying to log into daemon I get the cert then prompted with failed login. I am also not getting anything showing up in my logviewer (gnome). For most other daemons I have had them automagicaly pop up (denyhosts for example) how can I get nessus to show up as well.
After running
Code:
nessus-fetch --register <Activation Code>
I got
Code:
nessus-update-plugins could not be found in your $PATH
When I try to run a scan on localhost I get the message "nessusd returned an empty report".
Here's the entry in nessusd.messages
Code:
[Mon May 25 00:30:03 2009][13188] user mickey.harvey : testing 127.0.0.1 (127.0.0.1) [13189]

I would like to get the scan working and make sure that nessus is updating the plugins. I have been looking though the nessus documentation and tried searching on Goggle without any success.
after some tweaking i managed to get nessus installed on my machine. However i'm running into an issue when trying to add a user.The nessus daemon is running on my machine, i've registered. I think everything is peachy in that regard, but when i run:
Code:
zachadmin@ubuntu:~$ sudo /etc/init.d/nessusd restart
$Shutting down Nessus : .
$Starting Nessus : .[code].....
Obviously the command not found is my error, from what i understand there isn't a default user placed in the first time.So essentially i have thie program installed, but i can't access it.
I have a large HD (1 TBytes) on my Server and I need to install 11 SP1. I want to use this server for software development (Web apps with Oracle DB and Oracle Forms). Can You suggest how to partition my HD for best use and performance ?
View 2 Replies View RelatedI have an 11.2 laptop and thought it was time to upgrade to 11.4. I downloaded the 11.4 X86-64 live cd and thought that I would check how it ran on my 11.3 desktop. This is a core i5 760 with an Nvidia GT240 graphics card and 4GB of DDR3 ram. The 11.4 live system shows the nouveau driver. The graphics performance is terrible. In particular windows are very very slow to resize and often don't resize properly. There are also some artifacts in some graphics. I eventually downloaded Flash which did seem to work moderately well, especially in full screen mode. The screen resolution is 1920x1080. I have never seen a windowing system work so slowly
While I always use the Nvidia proprietary driver, I don't know how I can test it via a live CD. The Nvidia driver in the repository is the 270 version and I think that I have seen reports of severe problems with the 270 version so that needs to be tested too. I always install the nvidia driver the really easy way via yast
Has anyone any idea why the KDE Live graphics are so slow? I will not go anywhere near 11.4 unless the graphics system is very much faster. Is there any way to test the nvidia proprietary graphics driver without installing 11.4?
The kvm and qemu packages are integrated into a single package, but this doesn't mean qemu is integrated into the kernel now in any way does it? I should still install kqemu to the the performance improvements, right?

This may just be more idle curiosity than anything else since the server still works. . . but it's really bothering me because I can't explain it.
My (limited) understanding is that the devel files are just the source files and shouldn't actually affect peformance.
Yet, prior to installing httpd-devel (and its dependencies), /etc/init.d/httpd restart takes about 2 seconds total. After installing httpd-devel, the "stopping" phase of the httpd restart take 5-7 seconds (which seems really long when you're just sitting there waiting on it.
yum install httpd-devel also installs the following for dependencies:
db4-cxx
db4-devel
cyrus-sasl-devel
apr-devel
apr-util-devel
openldap-devel
expat-devel
All but one of those are devel files as well. And here's the real kicker: Uninstalling them through YUM doesn't put things back to normal (even after reboot).
I'm no linux expert. But I wouldn't think installing devel files would have this effect or any effect like this since they're just source code files (?). Can anyone explain what's happening or give me tips on how I can watch the apache process stop and see what's hanging it up?
I'm running 32 bit Ubuntu 10.04 with 2GB RAM. Is my processor (AMD Athlon 64 X2) running sub-optimally?Given that a larger addressing space will make no difference to me (right now) would there be a performance gain or any other advantage to switching to 64 bit Ubuntu.

I'm using RADClock instead of the NTP client to synchronise my desktops.
Modern systems seem to be EFI based, and while there's a specific version of lilo that works with it, i can't seem to find any mention of a efi varient of grub (edit - on modern debian derivative systems there's grub-efi. Most references to it seem to be about various bugs in/for it tho) . In general, how well is EFI supported on linux?In addition, apparently windows 7 uses EFI to enable faster boot - 12 seconds or so with some systems. While a properly tweaked linux system could probably come close, are there any enhancements to the linux booting procedure that take advantage of EFI?

I have noticed that the HDD light is constantly flashing so I wondered if I couldnt use some of the Ram to create a ramdrive to speed things up . So ..my question ... what should I put on my ramdrive? My own thoughts were the var and usr directories. I would load the ramdrive at startup (which would slow down my startup) And Rsync back again on shutdown.Has anyone done this? Ive had a look through the forum but cant see anything ..but my search terms may not be all that good.

Does anyone here has any experience with the proprietary compilers? OpenWatcom, Intel and Pathscale? Does the performance gain is noticeable regarding the gcc...?In number crunching applications, i may say that ifort/ icc/ mkl yeld faster binaries than gcc.has anyone here already tinkered with OpenWatcom/PathScale...?

I have written a script as follows which is taking lot of time in executing/searching only 3500 records taken as input from one file in log file of 12 GB Approximately. Working of script is read the csv file as an input having 2 arguments which are transaction_id,mobile_number and search the log file having these two strings with one more static string that is "CustomCDRInterceptor",then format the searched data in prescribed format.
Code of script written is as follows:

My Firefox configuration is tricky:
Firefox runs at separate restricted user account which cannot connect to main X server.
Firefox uses Xvfb (virtual "headless" X server) as X server.
x11vnc is running on that Xvfb.
On the main X server there is vncviewer running that connect to this x11vnc
On powerful laptop (Acer Extensa 5220) it seems to work more or less well, but on "Acer Aspire One" netbook it is slowish (on a background that firefox is loaded with lots of extensions).How to optimise this scheme? Requirements:
Browser cannot connect to main X server.
Browser should be in chroot jail (no "suid" scripts, readonly for many things)
Browser should have a lot of features (like in AutoPager, NoScript, WoT, AdBlockPlus)
I'm using mplayer and libcaca on Gentoo. My framebuffer (uvesafb) is running at 1920x1200 (I don't know how many characters that is) and mplayer has problems filling up the screen, so video and audio lose synchronization.
View 1 Replies View RelatedIs there a 'top' like command for monitoring the GPU and memory usage of a video card? I am most interested in Linux commands, but and OS would be interesting. I strongly suspect that for a group of my systems the video cards are being under-utilized (but I have no idea by how much) and would like to re-allocate funds to other bottle-necks. We are using higher end cards, so the price difference between cards is significant.
View 1 Replies View RelatedI've recently been experimenting with glxgears, but found people saying this is not an ideal benchmark tool as there are many variants; for example resizing the window affects the FPS tremendously.
I'm interested in testing the difference between using the proprietary ATI driver and the open source driver and also the performance under various distributions.
What's the best software to benchmark graphics cards?
I am running openSuse 11.2 (32-bit), my CPU only supports 32-bits. I have a hardware RAID device. My system has 4GB of RAM. When I configure my system to only use 3GB, 2GB, or even 1GB, using mem=1024M in grub, my RAID performance is much better then when letting my system use the default 4GB available.Can anyone explain to me why this is? Is there anything I can do, i.e. kernel configuration, that will help performance when running with all 4GB enabled?
View 5 Replies View Relatedif I make more partitions rather than creating single one, will I get more data access performance? E.g Instead of keeping 1,5TB partition, create 5x300MB and keep different data in different partitions? Logically hard drive will spend less time on finding data in smaller partition then in bigger one, right? Is there any statistics for performance vs size?
