[gentoo-user] Creating a wireless router
Greetings, I want to setup a wireless router for the first time using WPA. Here is the setup I want... Internet---Gentoo Wireless Router---My Computer I have configured my kernel properly from what I can tell and emerged madwifi. However when I modprobe ath_pci nothing shows up. When I do ifconfig -a I get... ath0 Link encap:Ethernet HWaddr 00:19:5B:80:F2:D8 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) eth0 Link encap:Ethernet HWaddr 00:0E:0C:C4:A8:87 inet addr:66.11.182.5 Bcast:66.11.182.255 Mask:255.255.255.0 inet6 addr: fe80::20e:cff:fec4:a887/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:75109 errors:0 dropped:0 overruns:0 frame:0 TX packets:48454 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:100 RX bytes:95609829 (91.1 Mb) TX bytes:6195064 (5.9 Mb) Base address:0x9000 Memory:ec02-ec04 eth1 Link encap:Ethernet HWaddr 00:0E:0C:C4:43:0F inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0 inet6 addr: fe80::20e:cff:fec4:430f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:66264 errors:0 dropped:0 overruns:0 frame:0 TX packets:111528 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7189540 (6.8 Mb) TX bytes:96020126 (91.5 Mb) Base address:0x9400 Memory:ec04-ec06 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:177 errors:0 dropped:0 overruns:0 frame:0 TX packets:177 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:99775 (97.4 Kb) TX bytes:99775 (97.4 Kb) ppp0 Link encap:Point-to-Point Protocol inet addr:66.11.182.5 P-t-P:192.168.200.1 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1452 Metric:1 RX packets:74713 errors:0 dropped:0 overruns:0 frame:0 TX packets:47995 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:93641841 (89.3 Mb) TX bytes:4912135 (4.6 Mb) sit0 Link encap:IPv6-in-IPv4 NOARP MTU:1480 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) wifi0 Link encap:UNSPEC HWaddr 00-19-5B-80-F2-D8-38-80-00-00-00-00-00-00-00-00 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:199 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:11 However my computer doesn't show a wireless network to connect too.

When I do ifconfig -a I get... Hi there, I assume you've read http://gentoo-wiki.com/HOWTO_Building_a_Wireless_Access_Point ? When I wrote this I was using a Prism54 card, not an Atheros-based one. I have used Atheros since (and would as a matter of choice), but it appears I never got around to updating the wiki (and I won't update it in the future because, basically, maintaining wikis is a lot of work). Further reading reveals inaccuracies in the current article. Madwifi requires an extra step when creating the interface: wlanconfig ath0 create wlandev wifi0 wlanmode ap http://madwifi.org/wiki/UserDocs/SimpleAccessPoint IIRC you can do this in your modprobe or udev rules (preferable), or as a preup stage in /etc/conf.d/net IIRC a udev (??) rule is created automagically when you first create the interface and it's this you can edit to make it so that it automatically comes up as an AP, rather than in client mode. You state that However when I modprobe ath_pci nothing shows up, but the interface HAS come up - it's shown as wifi0 in the ifconfig output you post. I don't use WPA but when using WEP (which I would advise you to get working first) you then have to: ifconfig wifi0 up iwconfig wifi0 mode Master essid foobert channel 11 iwconfig wifi0 essid foobert channel 11 key aabbccdd (or, obviously, the equivalent in /etc/conf.d/net - this is well documented in /etc/conf.d/net.example) Anyway, Google madwifi master mode should give you plenty of fodder to get things up on a one-off basis using manual commands so that you can see it's working. You then just have to figure out how to integrate what you've learned into the Gentoo bootscripts - hopefully Google gentoo madwifi master mode will help. However my computer doesn't show a wireless network to connect too. I assume you mean your OTHER, client, computer by this. When posting problems it helps to be as explicit as possible - for example when posting the ifconfig output it would've been beneficial to post EVERYTHING you did in order to get there. Oh! Also, the great thing about the madwifi drivers is that you can great virtual APs - as long as they all have the same channel then you can have wifi0, wifi1 and wifi2 on the same card (just `wlanconfig ath0 create wlandev wifi1 wlanmode ap wlanconfig ath0 create wlandev wifi2 wlanmode ap`). You can run one of these open, one as WEP and (presumably) one as WPA, bridging the secure networks with your wired LAN (for best integration) and NATting the open network using iptables (so you can give clients free or filtered internet access without having to worry about them accessing LAN services. This is useful if you have a Nintendo DS, which doesn't support WPA). Please post back any problems. Stroller. -- gentoo-user@lists.gentoo.org mailing list

It said to go to another article when using MADWIFI which told be to use the command... ifconfig ath0 down wlanconfig ath0 destroy wlanconfig ath0 create wlandev wifi0 wlanmode ap Right. I didn't see that when reading the HOWTO today, but it is the same command as I gave in my message. Which I did, but now when I try to startup net.ath0 I get the following... penguin init.d # /etc/init.d/net.ath0 start * Starting ath0 * Starting wpa_supplicant on ath0 ... ioctl[SIOCSIWMODE]: Invalid argument Could not configure driver to use managed mode [ ok ] * Starting wpa_cli on ath0 ... [ ok ] * Backgrounding ... This.. ioctl[SIOCSIWMODE]: Invalid argument Could not configure driver to use managed mode [ ok ] ...was not there before, what do I do? Give fuller information. What does `dmesg` say? What does /var/log/messages (or whatever) say? What do wpa-supplicant logs say? I believe it's possible to compile wpa-supplicant with / without madwifi support, so you should check that. I'd also imagine it might be possible to compile madwifi with or without mastermode support, so you may need show that relevant kernel options have been compiled. I believe that ioctl errors are generally associated with trying to tell hardware to do stuff it can't do. So drivers may be the cause here and I would certainly expect `dmesg` to be more verbose. I would STRONGLY advise you to get the access-point working in master mode UNENCRYPTED before continuing to WEP or WPA configuration. Making *incremental* changes help isolate the problem. Finally, unlike some, I have no objection to top-posting. What pisses me off immensely is *changing* the quoting-method of the thread. If you are the first person to reply to a post then by all means top- post; subsequent replies top-posted may be logical and readable. But if someone has replied by bottom-posting then top-posting breaks the continuity of the message. I have to read one level of quoting at the top of the message and another level at the bottom. Leaving aside any other debates about top- versus bottom-posting this does not make any sense AT ALL. Please do not do it! Stroller. -- gentoo-user@lists.gentoo.org mailing list
Re: [gentoo-user] Creating a wireless router - I got it working!
ok, I got it working without encryption. Here is what I did I configured my kernel according to these webpages... http://madwifi.org/wiki/Requirements and http://madwifi.org/wiki/UserDocs/KernelConfig ...then I configured my system as follows... 1)Add madwifi to USE flags 2)emerge wpa_supplicant 3)emerge madwifi-ng and madwifi-ng-tools 4)cp net.eth0 net.ath0 5)rc-update add net.ath0 default 6)nano /etc/modprobe.d/ath_pci and add the following... options ath_pci autocreate=ap 7)add the following to /etc/conf.d/local.start ifconfig ath0 down wlanconfig ath0 destroy wlanconfig ath0 create wlandev wifi0 wlanmode ap 8)nano /etc/conf.d/net and add mode_ath0=Master essid_ath0=CarsonNet config_ath0=( 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255 ) wpa_supplicant_ath0=-Dmadwifi Then I configured dhcpd and bind which I won't get into and it all worked. I now have a wireless access point with Gentoo! So my question now is, how do I enable WPA encryption? -- gentoo-user@lists.gentoo.org mailing list
