CPU lines multiplying like rabbits?!?

By marty | Published: February 3, 2008

So, I admit it’s been a while since I really looked into x86 hardware, but I remember a time when Intel and AMD (and any other CPU manufacturer…) had 2-3 lines at most. There was the one aimed at servers pitched at a speed/feature set, the one aimed at desktops pitched at a price point and possibly a mobile chip pitched at a low power/long battery life scenario.

Now you have 47 different types.

I think their thought process must go:

  • Is it low power or high performance?
  • How many cores does it have?
  • Uniprocessor only or made for multiprocessor systems?
  • 32bit or 64bit?
  • Is it built down to a price or up to feature set?

…and then they make one of every possible combination!!!

And then throw in some variations in bus speeds and L2 cache sizes in the different models in the same line. To top it off give the models confusing names not based on any specification of the acutal CPU. Whimper.

Almost makes you want to be a luddite…

Many to one SNAT on Cisco IOS

By marty | Published: February 1, 2008

So, at $work[0] we needed to do a “many to one” SNAT on Cisco IOS. I’d only ever previously done this by SNAT’ing to an interface, however this required specifying the IP.

My Google-fu failed me, I could turn up how to do the “SNAT to interface” and “SNAT one to one from a network to a pool” but not quite what we needed.

So I thought I’d try having a pool with a single IP in it, ala:

ip access-list extended SNAT_SRC_ACL
permit ip w.x.y.z 0.0.0.63 any
ip nat pool SNAT_POOL a.b.c.d a.b.c.d netmask 255.255.255.0
ip nat inside source list SNAT_SRC_ACL pool SNAT_POOL overload

Which worked!

And then five seconds later a workmate found a site that described exactly this technique. Argh!

Back blogging again…

By marty | Published: January 30, 2008

So, it’s been a few years. A few things got in the way of having enough spare time to write anything down. Little things, like no longer being a student and starting a full time job. Meeting a girl and marrying her. Buying a house. Having a baby. Little things…

It’s taken me a little whilst to even get started again because of the old manky MovableType install which had been my previous platform. I’ve tossed that all aside in favour of Blosxom. When I find the time (!) I’ll try to extract some of the old entries out and put them here.
