Apps : Get-Console : When iPad meets Cisco

-

Despite all reservations to iPad as a device which might be useful in day-to-day IT Pro activities (was thinking about it more as a toy than tool) I found it really handy after some time. One of main reasons I found iPad cool IT tool was ability to connect to Cisco console port and configure Cisco devices.

Yes, it is possible to have Cisco console cable which connect to iPad and application which allows to configure Cisco via Console from iPad 🙂

Config snippets : Cisco : Turning lightweight Cisco 1142n into autonomus Cisco 1142n AP

-

So, finally I got 6 brand new Cisco 1142n wireless access points. They all are lightweight access points, which means that more less Wireless Controller is required to get them to work. Unfortunatelly due to many circumstances I have purchase of Wireless Controller delayed, so for now have to turn all of those into autonomus wireless devices. That means that IOS has to be replaced on those devices to allow 1142n be fully configured.

  • Original software which came on devices was: c1140-rcvk9w8-mx.
  • New software I had to deploy on all of them to make them autonomus is: c1140-k9w7-tar.124-25d.JA1.

But how the whole process happenes? Here are all steps I took to make lightweight AP become autonomus wireless access point:

Config snippets : Configuring static IP address on Debian 6.0

-

Just quick config snippet for Debian 6.0 which I came across when setting up few Debian Linux 6.0 virtual machines for recent network LAB. By default network adapter is set to get IP address from DHCP.

/etc/network/interfaces – dynamic IP address configuration

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface auto lo iface lo inet loopback
# The primary network interface allow-hotplug
eth0 iface eth0 inet dhcp

How-to : Using WebSVN as RANCID repository access tool

-

In previous articles in the RANCID series I described:

So, we have RANCID collecting configuration from network devices to repository with version control. Only question is how to get access and make use of information collected there.

In this part of RANCID stories I will show how to install and configure WebSVN to access RANCID repository via web browser.

How-to : Adding devices to RANCID

-

Some time ago I described How to : Install RANCID on openSUSE 11.4 “Celadon”. However, just after installation RANCID will do nothing without proper configuration.

So, in this lab I will show how to:

  • create group of devices in rancid
  • add information about credentals to RANCID
  • add 2 Cisco routers to that group
  • collect configuration from routers
  • setup cron task to run rancid automatically

Systems which will be used to demonstrate how to add device to RANCID and collect configuration:

  • lab-gw-01 – IP: 172.16.90.5 – openSUSE witn RANCID – installed on VMware Workstation
  • lab-r1 – IP: 172.16.90.123 – Cisco router – started on GNS3
  • lab-r2 – IP: 172.16.90.124 – Cisco router – started on GNS3
