10 May 07 Adventures with the Cisco 871W (Part 1)
I just bought a Cisco 871W Integrated Services Router for home. This is an attempt to add to my mad skillz by adding IOS and having a little fun learning in the process.
The box arrived today. Inside were the router, a power supply, serial and ethernet cable, manuals, and antenna for the back of the unit.
I plugged the 871 into the wall and used the serial cable to attach it to my laptop. Boot up hyperterminal and set the serial settings to 9600 baud, 8 bit, no parity, 1 stop bit and no flow control. The router shows a splash screen telling you to log in with the username cisco and the password cisco. Since factory passwords are bad, that is the first thing I wanted to change.
I logged in with the credentials provided and then floundered about for a bit trying to remember my ancient IOS skillz.
First I needed to get the machine into configuration mode. Since the account (cisco) that I logged in with was already at privilege level 15 I did not need to enable privileged EXEC mode.
yourname# configure terminal
yourname(config)#
There we go! Now I was in configuration mode. Now I needed to add my new administrative user and password to the config.
yourname(config)# username admuser privilege 15 secret 0 secretpasswd
yourname(config)#
Now I could log out of the cisco account and into the admuser account.
yourname(config)# exit
yourname# exit
Press RETURN to get started.
User Access Verification
Username: admuser
Password:
yourname#
We have access as the admuser account, however the cisco account still exists. Need to fix that…
yourname# configure terminal
yourname(config)# no username cisco
yourname(config)#
Much better. Now, as you may know, when you have made a change to a Cisco IOS config, you are editing the running configuration. This means that we need to save the running configuration. Prompt more floundering on my part until I realize that you cannot save the configuration in config mode.
yourname(config)# exit
yourname# copy running-config startup-config
Destination filename [startup-config]? ENTER
Building configuration…
[OK]
yourname#
Woohoo! Got my first configuration change saved in the startup configuration. Now for some more floundering before my next post.
