Hardware Problem - 9.2 PRO first Installation ...
Hi, im new to Linux and have decided to start with SuSe 9.2 PRO. Now i have a SuSe Linux working 90% (to start with), just need some help with two hardware issues [SCANNER & WiFi adapter]. 1.- I have a HP ScanJet 3770 USB scanner that YAST doesnt recognise. Is there a way to set it up? I tried Generic HP ScanJet but it doesnt work. 2.- I have 3CRDAG675 PCI WiFi network adapter that YAST recognises. I set it up without encryption and it works ok, but when i try to set it up as it should be, with encryption, things dont work. The info as shown in the AP is: SSID: cmp1 Channel: 6 SSID Broadcast: Disabled Security Mode: WEP WEP Encryption: 64 bits 10 hex digit Default transmit key: 1 Passphease: notthisone key 1: B02C84841C AP MAC: 00:00:00:00:00:00 (not real) whats the correct way to set it up using encryption? Is there a way to force a connect to a different AP (cmd2...)? 3.-When SuSe starts i see a black screen showing lots of infos and a green DONE beside it, but there is a RED failed that scrolls too qickly and i just cant read it. Is there a log where i can check whats going on? I hope someone can help me or at least point me to a correct place where i can get more info. Thanks in advance.

You will notice your model is not even listed, so there is little hope to get it working reliably. The Epson scanners seem to be best at working with Linux and many of the HP's I've seen that do work, are not the best quality or most reliable. -------------- regards, Lee -- --- KMail v1.8 --- SuSE Linux Pro v9.2 --- Registered Linux User #225206 There's no problem so awful that you can't add some guilt to it and make it even worse! ...Calvin & Hobbes

Not exactly true.... The HP ScanJet3770 is listed on the Sane website... but as unsupported: http://www.sane-project.org/unsupported/hp-scanjet-3770.html A little Googling will lead you to this SaneFAQ: http://www.xs4all.nl/~ljm/SANE-faq.html and in section 3.2 there is a specific reference to the HP 3770 and a link to this site: http://www.cyberbaladeur.fr/telechargement.htm l which.... has a driver for this scanner. The readme file in the tar.gz file is fairly detailed... looks to be good install instructions.. refernces to the various dependancies and where to get them etc. I have a different HP scanner, so I can't vouch for how good this 3770 driver works. By the way... found this info in about 15 seconds of Google searching <hint hint> :-) C.

Okay, I *think* I know what might be causing your WEP problem: it's that "passphrase" setting. WEP encryption is standard across all brands of Wifi gear, but *generating a key* from a passphrase isn't. So, assuming I understand your information correctly, it looks like your AP has been set up to create a WEP key from the phrase 'notthisone'. The hex key is 'B02C8481C' -- which you should probably change, btw, now that you've made it public. What you need to do is make sure that the hex key matches on both ends. In YAST, when you type in the key, select the little button for "hexadecimal" and type in what your AP shows as "key 1". This should match up both unit's WEP keys to match each other. You'll probably see that both your AP and your card have settings for "passphrase." What that does is generate a hex key from whatever you type in, but even if you type in the same phrase on both ends, YAST probably generates the hex key using a different algorithm than your AP does. So you need to make sure that the 'raw' hex key matches on both ends. Hope this helps. As far as the other: the commands you want to study are iwconfig and iwlist. They both operate with a lot of options. You'll want to read up on them. They're very useful, but I have encountered some problems with them, in that my YAST settings seem to periodically overwrite settings I set with iwconfig and iwlist. So far, when I want to change between my home network and a public hotspot, I have to go into my YAST settings, change my encryption, and reboot. There's been quite a bit of mail going around on this list just in the past couple weeks concerning my (and others') problems with this -- checking the archives might help you. It's been suggested that I install a program called wificonfig, which is supposed to help manage multiple wifi connections, but I haven't got around to it yet (maybe this week...).

I hope nobody minds if I add a few points. One is that WEP isn't truly secure, even with the shared-key technology. If the NIC is capable, you're better off using WPA-PSK. I haven't found this one used much in cybercafes though. Second, you don't have to reboot just to inject new settings into your wireless configuration. Just make the changes in your ifcfg-boofar file in /etc/sysconfig/network/ and run "ifup boofar". Second + 1, you don't need wificonfig... at least not if you're using v.9.3. Just rename a successful ifcfg-* file to, say, ifcfg-homewifi. And rename the ifcfg-* file that works at your cybercafe something like ifcfg-mochajava. Then, when you want to start up your wifi for one of these places, left-click on the graphical "X" in the top panel and, voilà, those configurations-- homewifi and mochajava-- will be appear in a drop-down... click on the one you want, it will be loaded, and the card started up with it.
