Diggnation - Get your tech news

Wed, 24 Sep 2008 13:36:50 +0000
I recently stumbled upon Digg Nation, a kind of mangled subsidiary of digg.com. Basically two guys, Kevin Rose and Alex Albrecht sit down frequently and discuss the articles on digg.com that have got the highest amount of diggs.
There is some pretty whacky stories included but it’s an excellent video and kept up to date frequently, ...]

IE Dynamips Lab2

Thu, 09 Oct 2008 02:42:43 +0000
I’ve always believed, as some say, that breaking things and then fixing them is the best way to learn.  Well, I must have learned a frickin’ great deal after breaking redistribution on this lab.  Unfortunately I could not move past this section to the other items until it was working properly.
After cheating a bit (okay ...]

The Poor Man’s CCIE Lab Near Complete

Fri, 29 Aug 2008 18:36:28 +0000
I’ve been accumulating a bunch of equipment now for quite some time…trying to get to the point where I could finally put together a half way respectable home lab for studying.  Last night I pulled an all nighter setting up most of my home lab!  My goal was to replicate the IPexpert R/S topology the ...]

IP Expert Lab 3 - Script Feedback

Wed, 24 Sep 2008 18:31:30 +0000
Below is a response I had from Tyson Scott at IP Expert - he is the guy who writes the grading scripts. Its good to see that they feedback in this way, and have made the appropriate changes to the grading script.
Strange to me how you can issue the same command on five different routers.

CME - Caller ID block

Sun, 16 Jul 2006 22:06:47 +0000
For both internal and external calls
ephone-dn
caller-id block
* This does not apply for E1R2, because caller id blocking is a flag in the setup messages and E1R2 does not support that. This does not apply for FXO, because caller id is controllerd by Telco on FXO. Use translation patterns to change caller ID to null
Only external ...]

IPCCX - provisioning CTI port and Media termination groups

Tue, 25 Jul 2006 00:29:41 +0000
CTI ports take only 1 ms to reinitialize (ie, to get back to operation after a call is disconnected), but CMT groups will take upto 200 ms to reinitialize. IPCCX will not answer calls if there are no CMT ports available. So make sure you provision 10% more CMT ports than CTI ports.
