Installing Minicom to connect to Cisco router using console cable.
I bought this Connectland usb/serial connector to configure my Cisco routers. Since now I’m using Ubuntu, this Linux just picks up the connector.
[4309733.840000] usb 2-2: new full speed USB device using uhci_hcd and address 5
[4309733.936000] pl2303 2-2:1.0: PL-2303 converter detected
[4309733.940000] usb 2-2: PL-2303 converter now attached to ttyUSB0
Then I installed minicom.
$ sudo apt-get install minicom
Run the minicom program and using command CTRL-a z o (inside minicom) to configure the minicom serial port. Make sure the configuration look like this.
A - Serial Device : /dev/ttyUSB0
B - Lockfile Location : /var/lock
C - Callin Program :
D - Callout Program :
E - Bps/Par/Bits : 9600 8N1
F - Hardware Flow Control : Yes
G - Software Flow Control : No
Save the configuration with whatever name you want. In this case is “cisco”.
Next time you want to configure your router using minicom, just type “minicom cisco”
Installing and setting TFTPD in Ubuntu
1. Install tftpd and related packages.

{
protocol = udp
port = 69
socket_type = dgram
wait = yes
user = nobody
server = /usr/sbin/in.tftpd
server_args = /tftpboot

$ touch /tftpboot/hda.txt $ chmod 777 /tftpboot/hda.txt $ ls -l /tftpboot/ total 0 -rwxrwxrwx 1 davids davids 0 2006-03-27 23:04 hda.txt $ tftp 192.168.1.100 tftp> put hda.txt Sent 722 bytes in 0.0 seconds tftp> quit $ ls -l /tftpboot/ total 4 -rwxrwxrwx 1 davids davids 707 2006-03-27 23:07 hda.txt
(Stupid) City Manager vs. Computer Engineer
Fate can sometimes lead someone who has inexorable stupidity to have big responsibilities. For those who has been working as an engineer, most of you, I believe, had come across to find somebody that inevitably stupid and be one of your supervisor.
CentOS engineers had several times trying to explain to this person the root of the problem yet he still arrogantly trying to report this case to FBI. It makes me wonder, It must be hard enough to manage a city and being a system administrator.

Reporting a Bug to Microsoft(tm) and get charged 35 USD
I wrote an article about Fernando Gont, a person who had problem submitting a bug to Microsoft (and several other vendors). Actually he did manage to file the bug and I was not sure whether Microsoft(tm) charged him or not (probably not). However, this person got charged 35 USD for filing a bug on Outlook(tm) and Outlook Express(tm) and don’t forget this mere mortal had to go through complicated procedures just to file a bug!.
