wpa_supplicant

Hi,

I am running Centos 4.1 on a Dell D610 with ipw2200.

Any good howto for running wpa-psk?

I have searched and not found much related to RHEL or CentOS.

Faced with a similar dilemma a couple weeks ago, I just rolled my own and installed madwifi and wpa_supplicant manually. I'd guess dag or someone has them in RPM format somewhere.

I built an extremely simple launching script (below) and did minor tweaking to /etc/wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=0 eapol_version=2 ap_scan=1 fast_reauth=1 network={ ssid="YourNetworkID" psk="YourObnoxiouslyLongSharedKey" scan_ssid=1 key_mgmt=WPA-PSK }

It's by no means an exemplary system, particularly the init script which does no error checking and fails to handle return codes correctly. In the meantime, however, it works....

I'm pulling my hair out as I read this email. I tried getting this working this weekend. Compaq Presario with an Intel ipw2200. Seemed pretty safe. Wanted to get it running with WPA, same as you. I never got it to work and just ended up returning the wireless router (it was malfunctioning anyway, resetting even on the cabled computers) and giving up on it. It was a sad situation. I tried everything, including Ubuntu (which has some good how-tos), but nothing worked. I eventually I talked to some people on #wireless who said WPA wasn't ready for primetime on Linux. I don't know.
