putty tips and tricks windows on top

If you use Putty on a daily basis or have only encountered it in the CCIE lab exam then you will know what a great tool it is. Simple and effective (with no tabs!) Most people though may not use putty on a daily basis preferring something like SecureCRT so will not be familiar with changing putty settings. Here are a few of my putty tips and tricks. In this short blog post I will go through some of the changes I make to my putty client. When you are sitting the CCIE Lab exam you have 8 hours in front of a different keyboard, mouse and monitor. You want to try and make the experience as familiar as possible, well you can't change the mouse or keyboard or monitor,  but what you can change is the putty settings. The most annoying one … [Read more...]

BGP Peer in wrong AS

ccie 6 us 31oct12

When configuring BGP with a remote peer you might get the error message BGP peer in wrong AS *Apr 18 08:39:15.455: %BGP-3-NOTIFICATION: received from neighbor 10.0.12.2 passive 2/2 (peer in wrong AS) 2 bytes 0002 This means that you have mis-matched AS numbers in your BGP configuration. You can phone up the remote end and ask them what their AS number is. But if you cannot do that there is one way. The answer to this problem is given to you in the log message. The HEX number at the end of the log message 0002 is telling you that the remote AS is 2 If you change your neighbor statement to be 2 the peering should come up.

flux icon on rogers ccie blog

Ever notice how people texting at night have that eerie blue glow? Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen? During the day, computer screens look good—they're designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn't be looking at the sun. f.lux fixes this: it makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day. It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better. I have just installed this and an very impressed. At night it makes the … [Read more...]
