Cannot connect my Host system to Cassandra running on my Guest VM

I found a different way which is to use the:
Local Network or Host-only Network on your Virtual Machine

Today I did my first full install of Snap on a VM in my Ubuntu development system that runs VirtualBox.

This took me about 1h between getting all the files ready from our own APT repository, and then finding out all the setups needed (we have a few working installations, but we added all the necessary magic with time and did not clearly document all the steps yet... argh! so much to do!)

At some point, I wanted to setup the "domains" and "websites" tables on the VM. ...

Using non-default private key for Launchpad

As I was looking around for the way to specify the correct key for launchpad, I could not find it. Luckily the ssh process is running when it asks for the passphrase so I could see the URL used to access the launchpad server from Bazaar. It is:

bazaar.launchpad.net

The address is not visible by default because you use the lp: protocol instead of a full URI to access launchpad.

  Host bazaar.launchpad.net
    HostName bazaar.launchpad.net
    User <your launchpad username>
    PasswordAuthentication no
    HostbasedAuthentication no
    IdentitiesOnly yes
    IdentityFile ...

Useful online network tools

I'm starting this page and hope to think about it again at a later time when I find additional tools... but as I have network problems I often need these types of services to make sure I can get the information I need.

Apache log says: client denied by server configuration

I work with Apache a lot. It is a really good web server that has many options and features. Unfortunately, maybe it has too many of them!

I ran in a problem where a notification from one server to another would fail with the following error:

[Fri Oct 11 19:43:50 2013] [error] [client 162.226.130.121] client denied by server configuration: <path to file>

Looking at the error, I was first thinking that my script was generating the error. The fact is that my script does not generate error 403. It has a 400 and 500 but not 403.

So looking at the error I thought, maybe that's an ...

Setting up my home server with the NVG510 router on AT&T Uverse

My Rant

I got a new router as AT&T forced me to a new product called U-Verse. They are actually forcing all their users to switch to that new systems as the new optic cables are now installed and they probably have a goal to turn off their old infrastructure soon.

The old router I had would generate a gateway on their side. The router was just a router ...

A C++ implementation of a UDP client/server

I have noticed that quite a few people were trying to create UDP communication and I thought that proposing my class could help them. This is very basic as it does not define anything such as the size of a packet or any protocol to ensure arrival of the packets. However, it can be useful if you want to send a signal from one process to another, which is exactly how I use this implementation.

This code is part of the Snap! C++ implementation. It can be found in the corresponding SourceForge.net repository.

Installing a Nook on my Static IP Network

Barnes and Noble Nook (Electronic device to read books anywhere!)Introduction

Today I was requested by my wife to make her Nook work on our wireless network (she usually can use our neighbors but the connection drops all the time.)

The Nook makes use of DHCP only. So on my static IP address only network, it's kinda not going to work as is! (I must have static IP addresses for security so I can setup a strong firewall.)

So I had to go through a few hoops as follow to get everything to work. Interestingly enough I have not found another website that was talking about such things and their solutions on Linux.

Oh! Wait! Nookers are probably not Linux ...

Too many authentication failures for <username>

Today I tried to make use of sftp to transfer a website to SourceForge.net. Unfortunately, it kept giving me an error:

Received disconnect from <IP address>: 2: Too many authentication failures for <username>

I looked around why that would happen and could not really find anything decisive... until I found an issue in the trac system that SourceForge.net uses. That issue mentioned the fact that the ssh-agent could be the culprit.

It was. Somehow the ssh-agent was sending key after key after key... exhausting the number of keys that SourceForget.net will accept and thus made it

QEMU networking problems when trying to get it to connect with the host (bridging not working)

Virtual Box Bridging

I have a computer with Ubuntu 11.04 (the host) on which I installed a version of Ubuntu 11.10 (the guest) using QEMU. Both are 64bit on an i5 quad.

What I'm trying to do is allow the host to access the guest via a br0 bridge and possibly using all static addresses so they don't change on me (there still seem to be some DHCP going on the guest side and maybe that's part of the problem.)

When I start qemu with nic/user, it works as expected (well... somehow the nameserver 10.0.2.3 fails now... since I installed my br0 bridge, but I can fix the ...

Attack by Bots

Since the ZmEu attack, I've been watching my logs a little closer. I also found a page that I could not read (but Google could and was kind enough to provide a cached version.) That page listed many bots that are not nice bots. So? I decided to block some of them, especially those that use very bad URLs or load many pages too quickly.

The result is that I'm getting more and IP addresses in my firewall. Although they get removed in a schedule that I will not state here, I can tell you that each time I block tenth when not hundredth of useless hits (worst than that at times those could be
