Pop Quiz Friday – Redirect Users Web Traffic Going Out
This will be the maiden flight of my pop quiz series. I’m going to try and do them at least every other Friday, if not every Friday. I’ll give you until the following Thursday to put your answer in the comments section. Without further delay, here’s today’s quiz.
You have decided that you don’t want users going to GregSowell.com anymore…how unfortunate hehe. Instead of blocking GregSowell.com you want to redirect the users to an internal webserver at IP 192.168.2.2. The internal server will host a page that says something to the affect of “You are not allowed to view this page.” You are using public DNS, so no DNS query trickery 
Also, no squid or other proxy services.
I can quickly think of a couple of ways to accomplish this:
One way takes only a single command, but is the most basic.
The second takes 3, but is a little more clever in design.
MUM Poland
I saw that the Poland MUM is like a month away. Any of you guys going?
Looks like they will have some security lectures that should be interesting.
10Gb Routing and NOT From One Of The Biggies
So I got yet another Vyatta email…they send out a lot of updates. This one was touting 10 gig capability in their 3500 series 2U appliance.
Reminds me of a Jack and Jills from the 70s...hehehe
For the uninitiated, Vyatta is a routing platform built off of open source packages…sounds familiar, eh…hehe. Vyatta configs in files and doesn’t have a GUI and such. They thought a lot of speed. Anyway, back to the point of the post.
They say that you can do 10gig…what would keep Mikrotik from doing 10gig? They would need a 10gig interface for one, right. In steps the Neterion x3110 PCI Express 10Gb NIC.
This guy looks like it MSRPs for around $1000, which isn’t thaaaaat bad. You could snag a motherboard like this that runs around $230. I’m thinking you could pull everything off for less than $3000. 10 gig routing/firewalling for less than $3K is pretty impressive. Of course, MTK would have to add the drivers into ROS, but I assume if you wanted to really do it, they may oblige you.
Juuuust me thinking.
My Pan-Tilt Mikrotik
Posted by Greg in Hardware, Mikrotik, Networking, Wireless on February 1st, 2010
I had the desire, not the need, to be able to pan/tilt my Mikrotik AP from inside my house. It is a huge pain to go outside, climb the ladder, sit on the roof with my laptop and tune my AP. Yes I occasionally have to tune my AP. So I came up with a simple and relatively inexpensive option…A Pan-Tilt mount for a surveillance camera.
I found this guy on ebay for $99 with $20 shipping. Here’s my install:
As you can tell, the PT unit is about the size of a milk jug, so it’s pretty big.
The whole shibang
I used a tailor light hookup kit to connect my cat5 hookup wire to the PT unit.
Heat shrink and liquid electrical tape...I'm high dollar.
My superfly custom brackets that I bent…I bent them on my BBQ pit
I doubled it up.
I attached a piece of PVC to the top of the unit to hold the rootenna to. I then spray painted it to look, in the words of Rob, less “redneck.”
Soooo perdy.
A full 360 degree pan takes about 45 seconds.
I really only use pan, so I unhooked the tilt once I got it set.
Mikrotik R52Hn
Looks like MTK has put out a new high power version of their N card. See specs below. Looks like they will be retailing for around $50 over at Baltic.
Looks like a wireless card to me
Find Mikrotik OIDs
When looking for Mikrotik OIDs to do SNMP monitoring, you can issue the following CLI command:
1 | print oid |
An example would be:
1 2 3 | [admin@MikroTik] /system health> print oid
active-fan: .1.3.6.1.4.1.14988.1.1.3.9.0
voltage: .1.3.6.1.4.1.14988.1.1.3.8.0 |
Fun Boot Error From Mikrotik Server
This was an apartment server we had running off of a compact flash drive. After a reboot, it didn’t come back. When we got it back in the office and on a monitor, this is the error it presented.
Please attach it somewhere else
Where exactly would you have me attach it? hehehehe One of my favorite error messages
