Networking :: Bonding Of For Fault-tolerance (active-backup)?
May 14, 2010Just for the learning sake, I was going through this document for Bonding of Two Ethernet Cards for Fault-Tolerance (active-backup). Here, /etc/modprobe.conf is as
Code:
alias bond0 bonding
options bond0 mode=1 arp_ip_target=192.168.1.1 arp_interval=200 primary=eth0
Now, I just wanted to to know,
- What parameter is arp_ip_target and why it is used.
- Why the IP is 192.168.1.1, whereas the IP in /etc/sysconfig/network-script/ifcfg-bond0 is 192.168.1.5.
- Can I use the below /etc/modprobe.conf ?
Code:
alias bond0 bonding
options bond0 miimon=100 mode=1 primary=eth0
Debian Configuration :: Fault Tolerance / High Availability
Aug 19, 2015I work for a data center where we use a whole lot of VMware's "Fault Tolerant" Solution. As a personal project, I want to piece together an alternative solution out of open source software.
Here's my punchlist:
*Configure Debian (or build from scratch) to be as slimmed down as possible so that I may call it "Just Enough OS" or "baremetal"
*Install and configure Xen with XenMotion
*Prove that both the physical and virtual fail-overs work as intended
*Prove the automatic repair of failed virtual machines.
Fedora :: Boot Message Failure - Segmentation Fault
Aug 26, 2010Every time I boot up FC13 I get a boot message which is showing a failed task. The line is as follows:
Enabling the nvidia driver: /etc/rc.d/init.d/functions: line 530: 1174 Segmentation fault "$@"[FAILED]
Everything appears to be running fine on my system. This message is more nuisance that a functionality message. But I could be wrong.

Jun 19, 2010My laptop's been locking up in Linux (Ubuntu, Backtrack, Puppy) periodically for a while now. When it locked up, it was always immune to the magic of SysRq, which I thought might indicate a hardware problem. It became so bad that I had to stop using the laptop.
Today, when I turned it on and tried to boot into Fedora 12, I got the following error (just once, it just locked up at various points during the splash screen after this once):
double fault: 0000 [#1] SMP
last sysfs file:
CPU 0

RIP: 0010:[<ff
All the seemingly missing letters were really missing, not my typos.
As you can see, kernel version is 2.6.32.11-99.fc12.x86_64 and my laptop is a Sony Vaio TZ 250N (Core 2 Duo ULV 1.2GHZ). Note that with the other remaining kernels from the updates, nothing ever happened other than the locking up. The core temperatures hover pretty high, about 55-60C peak but this is still below the critical temp. Memtest came up clean when the problem first started happening.

Ubuntu Networking :: 'internal Fault. Hal Has Failed To Initiate' And The Wifi Connection Does Not Work
Jan 27, 2011I have an Acer one with this peculiar operating system which I don't understand. I have had it a couple of years and it has hardly been used. It has always worked well and connected up to my WiFi until today when after it has booted I get 'internal fault. Hal has failed to initiate' and the Wifi connection does not work. I am perfectly familiar with Windows but I haven't a clue with this one. Have found a post on this forum relating to this fault but I am afraid it was double Dutch to me. I don't even know how to access it's inner system let along enter any commands.

May 30, 2011there have been many posts about trying to use FF4 with graphic acceleration and i ran into an article that discusses some of the ramifications in doing so: Context and from the information presented, it appears that mozilla's approach is to blacklist graphic drivers that are not sufficiently "malware-proof" since code from the webpage is presented directly to the graphics driver.
i was not aware of this side issue and figured many others were also uninformed, but my thoughts are that some careful consideration should be done before implementing this new functionality. Perhaps someone more knowledgable could chime in with more concise information.

View 1 Replies View RelatedServer :: Implementing A Mailing List?
May 17, 2009Myself and a friend have our own small IT business; we mainly design and build web sites for other small businesses. One of the things we would like to offer to clients is the ability to relay email addressed to their company's domain to their own personal email address (either web-based, or hosted by their ISP).
Now, clearly there is a risk of our mail relay being marked as "open", and therefore becoming black listed as a source of spam. Not something that we want to happen!setting up such a system? I understand how I would go about configuring an MTA like Postfix or Sendmail to perform such a task, but I'm unsure how I would ensure that relayed mail is delivered and we're not labeled as spammers.
I did wonder if perhaps the "mail forwarding" options in a mail server like Zimbra would get around the issue by forwarding on messages inline or as attachments within new emails (so the messages would appear to be from the account hosted on our server).
Programming :: Implementing A Garbage Collector In C++?
Aug 27, 2009I'm interested in writing a generational garbage collector in C++. This is for a Python-like programming language project. I have used Boehm's garbage collector before, but I'm worried that it will have noticeable pause times (unacceptable for interactive programs). Since I can't really find any other C++ established GCs out there, I have been thinking of simply writing my own.
However, there are two essential ingredients I need for this:
- Some kind of write barrier mechanism that will notify my collector when something is written to a part of the heap
- A way for me to know the addresses and sizes of the stack, heap and global storage (the root sets)
how to implement write barriers (and how to get the stack, heap and global storage information) on the Linux platform? As an alternative, if you know of C++ GCs other than Boehm, I would also be interested.

What is the usage of inode? there are soft and hard items in columns 3 ,4 and 6,7. Which of them should be configured? here is the example by CentOS documents.

Debian Programming :: Implementing PyGtk For Python 3.3 In Wheezy
Sep 12, 2013I run Wheezy Xfce 64-bit. I went through the Synaptic listings and added Python 3.3.2 and Tkinter for it, and that works fine; but for some reason PyGtk is available only for Python 2.7, not for Python 3.3, unless I'm just using the wrong way to try to find it. Is there a PyGtk available for Python 3.3 in Wheezy, and, if so, how do I install it and then import it once it's installed?
View 1 Replies View RelatedProgramming :: Data Structure For Implementing A Text Editor?
Nov 15, 2010Options:A double linked list with fixed size character arrays. New nodes will be added when previous ones get filled. Dynamic arrays using realloc(). Linked list has the disadvantage of not having an O(1) search like an array but I think using realloc() will be more dangerous since it moves the whole block to a new location and if the new location is not big enough to hold the whole block, realloc fails !! this case will not occur with the linked list since its nodes are scattered.
