Connecting to Cisco Router console port using Linux

By arfs -
I tried to connect my Ubuntu laptop to Cisco Router console port. I did successfully.

What you will need:
  1. A roll-over cable (Cisco Console Cable). These are usually RJ-45 on the router side and serial on the PC side.
  2. If your laptop doesn’t have a serial port (like mine) you can get a 9-pin D-sub serial to USB cable. I got the BAFO USB Serial to DB9. I bought it in Ambassador Mall Kuningan Jakarta last night.
Get Connected:
  1. Connect all the cables: USB -> Serial -> Crossover –> Console Port
  2. Download and Install Putty.
    root@dion-laptop:~# apt-get install putty
  3. Make sure that the USB to serial cable is recognized.
    root@dion-laptop:~# dmesg | grep tty
    [ 0.004000] console [tty0] enabled
    [ 1.923508] tty ptyx4: hash matches
    [ 131.637904] usb 3-2: pl2303 converter now attached to ttyUSB0
    [ 173.768300] type=1503 audit(1243914954.561:5): operation="inode_permission" requested_mask="w::" denied_mask="w::" fsuid=0 name="/dev/ttyUSB0" pid=6127 profile="/usr/sbin/cupsd"
    Note:
    COM1 is /dev/ttyS0 in Linux.
    USB to Serial is /dev/ttyUSB0 in Linux.
  4. Run putty.
  5. Good luck!

Examining the DR/BDR Election Process

Routers Used : 3640 w/ NM-1FE-TX IOS : c3640-jk9s-mz.124-16a Objective : In this lab, observe the OSPF DR and BDR election processing using debug commands. Then assign each OSPF interface a priority value to force the election of a specific router as a DR. Scenario The backbone of International Travel Agency’s enterprise network consists of three routers connected using an Ethernet core. Asterix1 has more memory and processing power than the other core routers. Unfortunately, other core routers are continually elected as the DR under the default settings. In the interest of optimization, ensure that Asterix1 is elected the DR, because it is best suited to handle associated extra duties, including management of Link State Advertisements (LSA) for Area 0. Investigate and correct this situation. Step 1 Build and configure the network according to the diagram. Use the configuration files from the previous lab if available . Configure OSPF on all Ethernet interfaces. A switch or hub is req
