Dec 10, 2009I am having some trouble getting a VNC session to a new OpenSuse 11.2 32bit machine I have just installed.Fresh off the DVD, tried under KDE4 and Gnome with the same result (each time a fresh install).In YAST, I enabled remote administration, open the firewall ports, and then try and connect from remote client (in this case I have tried RealVNC from windows, and krdc from a Suse 10.x client and via HTTP) all result in the same blank black screen (http does get an X cursor echoed on the screen)

Aug 19, 2010I can't seem to get Remote Administration (vnc) working for the life of me. I tried the ip4/ip6 fix and every other work around I could find. I simply can't figure things out. I can't say I'm new to Linux but I can say that I am quite new to openSuse and the RPM world in general. My actual error isn't much of an error but that of the vnc window just being a black window that eventually times out.
As of now I access and configure the box vis ssh.I'm using:
openSuse 11.3
Gnome Desktop
Installed from gnome live CD
Ubuntu Networking :: Remote Administration Without Server Over Ineternet?

Ubuntu :: Setting Up Remote Administration On A Distant Machine?
Oct 30, 2010I'm try to assess the viability of of setting up remote administration on a distant machine. Just for background, the computer I wish to administer is located on a boat in Southern Ireland while I'm in SE England. Sadly, the the boat operator is a far better fisherman than computer user and every now and then some rogue sensor numbers get captured by the boat's computer and these eventually need operator intervention. Anyone who has tried to talk a non PC literate user through correction routines over a dodgy mobile telephone while the said user is trying to operate mouse/keyboard in an Atlantic swell will appreciate the problem.
However, there is a fairly good mobile phone broadband signal available in the area so I was wondering if there was anyway I could set up a point to point connection with the boat over this medium. That would allow me to administer the machine remotely.

Jun 21, 2011I'm currently trying to find ways to get in-depth knowledge of the Linux OS. To give a brief overview of where I am at right now, I am a computational science graduate student who does all of his work on *nix scientific clusters.I also took a lot of computer engineering and computer science courses in college, as well as being the stereotypical standard computer nerd growing up, so I'm somewhat familiar with computer architecture, though more from the hardware side.So I'm familiar (though I wouldn't claim to be an expert quite yet, by any means) with using Linux and C programming, and I have a basic grasp of generic computer architecture, but what I feel I really lack knowledge in is the specific details of the Linux. All the details of the boot process, exactly what the kernel does, how Linux handles memory management, etc. I'm having difficulty finding any information on this;all I can find is generic information targeted towards people who are just starting out, and the stuff I've found that talks about the kernel seems more oriented towards "you change setting X and Y happens" rather than what the kernel is doing.

Oct 10, 2010I just recently installed Fedora Server on my computer and I am planning on hosting my website on this server instead of paying for hosting.All of my files for my website are currently using php but for some reason when I moved them here to "test" them before launching the final switch, the PHP does not work.I have further investigated this issue to learn that my php files were written using:<? and ?> to start the scripts
Apparently I have to write <?php and php?> to make these scripts work now.Is there a way I can edit a system file to allow me to use both instead of having to change all my files?

General :: Looking For Ways To Manually Rebuild A Partition Table?
Dec 14, 2010I need to find a program or a way to edit the partition table and set the values and addresses for the partition boundaries manually. A while ago I had a very messy data loss that left me with a disk full of data but without a partition table (and without file indexes for some of the partitions on the disk). So, for recovery reasons I need to try lots of combinations of starting and ending addresses for each partition. Additionally it would be extra nice if I could do this with a live cd since I don't have the faulty drive attached to a working computer at the moment.

Unless there's a way to unlock it with software, I'll try switching the insides with the casing of another. I just want to know what is the best type of SD card or Mini SD adpter to do the trick, i.e. what has the best lock.

General :: Perl Useful In System Administration And Application Development On UNIX?
Sep 11, 2010It is just a general discussion on "How Can Perl Be Useful in System Administration and Application Development on UNIX and Linux Platforms"? I am doing pretty much well with Bash and PHP. In fact, I am learning and experimenting in depth in those two domains. The project that I am working for these days has several scripts which are written in Perl and Ksh. They interact with Ab Initio graphs and perform extensive jobs. Anyways, my current role doesn't require me to have knowledge of Perl but I don't see any harm in learning something new.
So, before I take it, I want to know how Perl can help me and what I can do with it as a UNIX / Linux System Administrator and Application Developer? I just looked at some of its keywords, functions, and commands. Perl Variables are identical to those of PHP. Conditional Statements, Loops, etc. are also much the same as found in any other computer languages. So, at first glance, I have got this feel that it wouldn't be much difficult for me to learn it. But what do you say? Do I really need Perl when I am focusing on PHP and Bash?

View 2 Replies View RelatedUbuntu Networking :: Cannot Get NFS To Work Both Ways?
Jun 15, 2010I have been using another Linux distro(Xandros) for 3 years on one computer and have just installed Ubuntu 10.04 on a different computer. I am trying to network the 2 computers via simple ethernet cards and a crossover cable so that I can gradually migrate applications, data and peripherals from Xandros to Ubuntu. I am completely new to Ubuntu and I am really struggling to get NFS to work. Each computer
can ping the other, so the hardware connectivity seems OK. I have shared the relevant directories from each computer. I have followed malco2001's ellent HowTo guide and have now reached the stage where Xandros, as client, can mount directories on Ubuntu, as server, and see the files but I cannot get Ubuntu, as client, to mount directories on Xandros. When I attempt this from Ubuntu, using the command
# mount -t nfs 192.168.1.2:/home/richard /mnt/PC2_richard
(I have already issued from Ubuntu: # mkdir /mnt/PC2_richard)
I get the message:
mount.nfs: mount to NFS server '192.168.1.2:/home/richard' failed: RPC Error: Success
The configuration of various files etc. is as follows:
Ubuntu
IP address: 192.168.1.1
[Code]...
I should mention that Xandros does not have nfs-kernel-server installed; instead it has nfs-user-server.I am sorry if I have omitted or done something really stupid but I have spent best part of a week on this with only partial success.

View 2 Replies View RelatedHardware :: Ways Of Measuring FLOPS
Sep 25, 2010I've found various programs and methods to measure FLOPS, but I don't seem to understand them. What is wrong with the following?
test-flops.py
Code:
#! /usr/bin/env python
float_increment = 1.03 # random
start = 57.24 # random
floating_point = start
for i in xrange(10 ** 6):floating_point += float_increment
Code:
PROMPT$ time ./test-flops.py
As far as I can see, this times a program that performs 1 million FLOPs (namely incrementation).
This outputs about 1.2 seconds on my (reasonably fast) machine, giving 840kFLOPS, which is much too low.This post may be in the wrong section; a C translation increments the result by three orders of magnitude (ie, py sucks), but this is still considerably less (~ 7-fold) than published values.
Programming :: Ways Of Handling The ADT Interface?
Nov 30, 2010During my read, "Code Complete",the author described the different ways of handling the ADT interface.He has wrote this passage:
Quote:
Option 2: Explicitly provide the data used by the ADT services. In this approach, you declare the data that the ADT uses within each routine that uses an ADT service. In other words, you create a Font data type that you pass to each of the ADT service routines. You must design the ADT service routines so that they use the Font data that's passed to them each time they're called. The client code doesn't need a font ID if you use this approach because it keeps track of the font data itself. (Even though the data is available directly from the Font data type, you should access it only with the ADT service routines.This is called keeping the structure "closed.") The advantage of this approach is that the ADT service routines don't have to look up font information based on a font ID. The disadvantage is that it exposes font data to the rest of the program, which increases the likelihood that client code will make use of the
ADT's implementation details that should have remained hidden within the ADT.
The problem is that it is a bit subtle in terms of coding for me. Can anybody give more concrete example, in working codes, especially in Java?
