Hi everyone:
I'm studying for the ICDN1 exam and I bought an old catalyst 2900 Series XL to have something to play with for studying.
I'm in a Linux only environment and my laptop doesn't have a serial connection, but I did find a USB to RJ45 cable that looks like a rollover cable. Has anyone tried this setup and had success? How did you configure things to work in Linux? I downloaded minicom but I can't seem to find the device to connect it to.
Thanks,
Rick

Comments: I did not need an usb to serial converter cable. It worked out just fine.
- Install minicom
- Find the name of your usb port with the following command
dmesg | grep tty
[ 0.000000] console [tty0] enabled
[4369985.708013] usb 3-1: FTDI USB Serial Device converter now attached to ttyUSB0
[4370808.468473] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
[4370998.270624] usb 3-1: FTDI USB Serial Device converter now attached to ttyUSB0
[4372325.714145] ftdi_sio ttyUSB0: FTDI USB Serial Device converter now disconnected from ttyUSB0
[4372359.720319] usb 3-1: FTDI USB Serial Device converter now attached to ttyUSB0
- sudo minicom -s
- Configure minicom
- baud 9600
- Hardware flow NO
- Change the device /dev/ttyUSB0 (Your output from the dmesg command)
- "Escape" to go back to the main menu.
- Next, you need to select "Save setup as dfl" and hit "Enter" to save these settings to the default profile. Then select "Exit Minicom" to exit Minicom.
- Restart minicom sudo minicom
