“The Dude” Abides

“The Dude” Abides

It wouldn’t be a stretch for you to think that I’m referring to the one and only “Dude”, that’s right, the White Russian drinking, carpet stealing, Dude from LA. But in fact, I’m talking about one of Mikrotik’s latest releases: The Dude Network Monitoring System.

The Dude network monitor is a new application by MikroTik which can dramatically improve the way you manage your network environment. It will automatically scan all devices within specified subnets, draw and layout a map of your networks, monitor services of your devices and alert you in case some service has problems.

If you happen to be using Mikrotik routers, The Dude also features seamless integration, allowing for a more unified network management platform. Best of all, The Dude is entirely FREE, thanks Mikrotik!

Microsoft Windows 7

Microsoft Windows 7

I have had a chance to toy with Microsoft’s latest beta offering, and I must admit that I am not too impressed. I am still complaining about bugs in their current stable Vista platform. Most people are still holding off on upgrading to Vista, and many are actually downgrading to Windows XP.

Windows 7 seems to be a minor update to Vista. I have found nothing spectacular with this system. The biggest improvement is what the MS camp is touting to be a more compartmentalized system that will (Finally!) allow components like Internet Explorer to be removed. The ultimate goal being to provide a smaller footprint on custom systems, such as netbooks or Media Center PCs where Linux systems are gaining a higher market share.

Microsoft is releasing it’s stranglehold on Internet Explorer to focus on it’s Windows Live endeavor. It now seems that Microsoft is swapping focus from their desktop applications and are now focusing more on Internet SAAS. This move is obviously an attempt to compete with Google’s online applications. Windows Live is a big part of Windows 7 and Microsoft is using this to funnel users into their services.

In conclusion, Microsoft is still the same old Microsoft. Windows 7 has no new innovations and is just another avenue of income for the folks in Redmond.

Graphing Tranzeo Wireless SNMP Stats Using Cacti

If you are trying to graph the link and noise levels of your Tranzeo wireless equipment on Cacti and are running into problems, changes are that you need to download this graph file TranzeoCactiGraph.xml.

Loading this file into Cacti will allow you to create Tranzeo specific graphs for any wireless Tranzeo equipment that may be deployed on your network. Simply make sure that SNMP is turned on in the Tranzeo control panel and you should be ready to start receiving the wireless statistics in Cacti.

Bonding/Bridging NIC/Network Adapter with Debian Etch

Bonding/Bridging NIC/Network Adapter with Debian Etch

Run: apt-get install ifenslave

Then edit /etc/modprobe.d/arch/i386:

alias bond0 bonding
options bonding mode=2 miimon=100 downdelay=200 updelay=200

Then edit the file /etc/network/interfaces and insert something like the following (as a replacement for the configuration of eth0 that you might currently be using). Note that XX:XX:XX:XX:XX:XX must be replaced by the hardware address of one of the interfaces that are being bonded or by a locally administered address.

Edit /etc/network/interfaces:

auto bond0
iface bond0 inet static
pre-up modprobe bond0
hwaddress ether 00:02:55:E1:36:32
address 10.0.0.199
netmask 255.255.255.0
gateway 10.0.0.1
slaves eth0 eth1

The special file /proc/net/bonding/bond0 can be used to view the current configuration of the bond0 device.

/etc/init.d/networking restart
