|
|
Hei dudes,
I have looked and looked in the forum nad the wiki, and did not resolve the problem:
1. I want to use wireless ONLY if eth0 failes, i.e. if my regular lan is not connected. This way I don't need to wait 40 seconds until it scans the ath0 and does not find any wireless. Moreover, I don't want any wireless if I have lan cable connected.
2. How do I use wireless without ssid , I mean, I want to use wireless in a cafe or in hte university, so the ssid changes all the time (or was it essid? sorry, I am quite a n00b in wireless). it is an unsecure connection also. How do I do that, I mean, how the configuration file etc/wpa-suuplicant.conf should look like?
Thanks a lot
Nadi |

Get ifplugd to control your wired interface. This is well documented.
A combination of baselayout-1.12.0_pre4 and wpa_supplicant-0.4.x will allow net.ath0 launching wpa_supplicant, and timing out after 1 second but we stay active scanning for AP's and when one comes in range we configure the interface correctly. Any earlier version of baselayout or wpa_supplicant won't do this.
I'm not sure if wpa_supplicant allows connecting to a non-defined ESSID yet. |

thanks UberLord. I will look into it today. I think I read that essid will work on the other method (iwconfig), so I will give it a try.

Although iwconfig (via baselayout) can connect to any publically available access point and configure for it there are some drawbacks
1) It's one time only - scanning and association only happen when net.xxx is run so you have to manually restart it to try and connect to something else
2) It will delay your boot times. baselayout-1.12.x supports backgrounding iwconfig scanning and connection, but this is experimental and may not work to your tastes. _________________ Use dhcpcd for all your automated network configuration needs

Hi,
I recently upgraded to baselayout 1.12.x, too. I have to network interface: eth0 and ath0. ath0 is my builtin atheros wireless card. I use /etc/init.d/net.eth0 and /etc/init.d/net.ath0 as symlink to net.lo since a while.
Code: | egrep "^\s*[^#]" /etc/conf.d/net
modules=( "wpa_supplicant" )
wpa_supplicant_ath0="-Dmadwifi" # For Atheros based cards
associate_timeout_ath0=20
config_ath0=( "dhcp" )
dhcpcd_ath0="-N -t 10"
config_eth0=( "dhcp" )
dhcpcd_eth0="-N -t 20" |
I use net.ath0 in a different runlevel and it shouldn't start up for default.
But since baselayout 1.12 net.ath0 starts up too. thereis the ath0 device, it is connected to my AP and net.ath0 -status says: started
rc-status does not show net.ath0 to be started.
So what's the problem?
Thank you in advance[/code] |
