Secure Wireless Internet on openSuSE 10


hello there!
I've recently installed openSuSE 10 (first time I try Linux) so I'm a newbie here. It was all going very well at home, the installation seems to have detected my wireless internet and it was working perfectly. However, everytime I go to university it will not detect the secure internet there, so I would have to boot in Windows to work on the internet in my university. I could live with that so I didn't complain. However, just today, my brother decided to put a security on our wireless conncetion at home and ever since I wasn't able to connect to the internet from home.

I'm trying my best to learn more about Linux, so I'm sorry if I seem to be too needy, but if anyone willing to help needs any information about my system, can you please tell me how to get it as well?

Thanks alot!

What type of encryption is being used. It sounds like you previously had an open wireless system at home, and you brother enabled either wep or wpa. If this is a wireless router like a Linksys, you can hook up directly ( wired connection ) to the switch and browse to the web interface. ( Assuming that the default password "admin" wasn't changed. ) From the interface you can cut and paste the key(s) from the browser to the yast configuration, or into the /etc/sysconfig/network/ifcfg-wlan0 configuration file.

The SuSE administrator's manual has full instructions on configuring the interface.

hi!
What do you mean by "web interface"? Do you mean the internet browsers? Where could I find those keys?

Yes, Linksys cable/dsl routers have a web interface at 192.168.1.1. A log-in dialog pops up. Initially the username should be left blank and the password is "admin". Other routers also have web based interfaces but the IP address may be different. The web-based configuration interface will be the same IP as the default gateway.

I would recommend using a 32 byte random number for the preshared wpa key.
I use the random device to generate on.
Code:
> dd if=/dev/random bs=1 count=32 | od -t x1 | sed -e '3d' -e 's/^.\{8\}//' -e 's/ //g' | tr '\n' '\000' ; echo
This one-liner will print out a 64 digit hexadecimal random key. Cut and paste it from the konsole output to the web interface key input field and your interface configuration. All devices will need the key, but a random key will be harder to guess than a passphrase.
