[opensuse] Long standing serial port issue in openSuse
by Roger Oberholtzer 28 Aug '08

28 Aug '08

I have a C application that access a GPS receiver over a serial port. Over the years, using Linux (SUSE variants back a long way), I have experienced a problem that has never gone away. Although it appears on the surface to be a programming question, I think it is really a kernel / serial port issue. As I see it in openSUSE, I am starting my quest for a solution here. The problem is that, after a variable amount of time, reads of the serial port stop blocking (as the port has been configured to do) when there is no data, and start returning immediately with errno set to EAGAIN. This can happen after 5 minutes of running the app, or after 5 hours. There is no discernible pattern. The code in the application is childishly simple: 1. Open the serial port in the C application, controlling it via termio(). 2. Do a blocking read on the port. 3. When data arrived, write it to a disk file. 4. Go to step 2. We have done variations on this theme. For example, setting the serial port to send SIGIO when there is data, and not doing a blocking read. It works great for a while. But suddenly the kernel starts sending SIGIO over and over, even when there is no data. This implies that at some lower level, the kernel thinks there is data to provide, even though the subsequent read will disagree. I would think that, since PPP is using the serial port, Linux's serial port code would be bulletproof. But I also think that such stability is perhaps present when the serial port is used as PPP uses it. For example, I would think that PPP data is of known sizes (headers of known size that report data sizes to be read), and may not do reads of any size. Also, PPP writes as well as reads. Our app never writes to the port. I can provide code examples. I do not think they will indicate anything unusual. Anyone else using the serial port to record data over long periods of time? If it is not a kernel issue, is it possible that there is some application that runs (X? something else?) that wakes up and interferes with the serial port? No serial port specific things seem to be changed. Baud rate and flow control remain unchanged. But maybe just opening it resets the blocking mode for all users? We do not use PPP and, AFAIK no applications that use the serial port are enabled. Could there be any apps enabled in a rather standard SUSE install that may occasionally interfere with the serial port? -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Kapellgränd 7 P.O.

[opensuse] USB MODEM
by Danesh Daroui 28 Aug '08

28 Aug '08

Hi all, I want to buy a USB MODEM and wanted to ask if anyone has had such experience. I have read very disappointing stories about USB devices not working with Linux systems. But I have experienced external DVD drive and USB memory which work fine with OpenSUSE. Any tip would be appreciated. Thanks, Danesh -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

[opensuse] Joining an Airport network.
by Klaas. 28 Aug '08

28 Aug '08

Hello, I managed to solve a couple of prpblems on the road to connection, which I'll document later if I get this set up to work properly - loaded the firmware in openSuse - obtained the proper keyword for my Airport network. - Network Manager detects my network and joins it. Now however I still cannot get any response from any of the systems in my network or from the outside. This is with openSuse 10.3 - Gnome on a Mac Mini PPC. The internet connection functions well with a wired connection as well as under Mac OS X with a wireless connection. For the openSuse wireless I compared the Mac output from ifconfig to the output from the openSuse setup and changed some of the differences (Broadcast) with ifconfig. Actually I spend so much time on this that I am ready to give up. But maybe there is some kind person out there who can give me the last hint? greetings, Klaas Punt -- To unsubscribe, e-mail: opensuse+unsubscribe(a)opensuse.org For additional commands, e-mail: opensuse+help(a)opensuse.org

Re: [opensuse] opensuse 11.0 sound messed up.
by Vahe Avedissian 28 Aug '08

I sent this over the weekend but got no replies. I thought I'd re-send it... Vahe ----- Original Message ---- From: Vahe Avedissian <vyav(a)yahoo.com> To: opensuse(a)opensuse.org Sent: Saturday, August 23, 2008 10:03:40 AM Subject: [opensuse] opensuse 11.0 sound messed up. Folks, One of the latest YOU messed up my sound which worked perfectly (for many years). My sound driver is the snd-intel8x0(nvidia sound card). I can fix sound by one of two ways: 1. run these commands(http://en.opensuse.org/SDB:Sound_Card_Makes_a_Noise_After_KDE_Star…: * rcalsasound stop * rm /etc/asound.state * rcalsasound start * alsactl store 2. un-install my sound driver and then re-install it. The problem is after doing so sound works fine untill the next reboot. After a reboot soundstill works about 50% of the time, the rest of the time I have to repeat this procedure again and again. How do I make this a permanent fix? Also, I noticed (around the same time I made these updates) that if I run XMMS I get the "kdeinit CheckHardware executible not found" error message. I re-installed the "desktop-data-opensuse" rpm which provides this executible but that does not solve the problem. Any idea how I can fix this?

[opensuse] Problems with zypper and software repositories
by Claude Fuhrer 28 Aug '08

28 Aug '08

Hi Since a couple of day, I've trouble with the software repositories for zypper (opensuse 11.0 x_64). Yesterday, I've made a "zypper clean -a" and then a "zypper refresh" as root. Since then, I receive the following error message: The repository 'openSUSE-11.0-Oss' is invalid. Can't provide /suse/setup/descr/EXTRA_PROV : Can't copy /var/adm/mount/AP_0x00000006/suse/setup/descr/EXTRA_PROV to /var/cache/zypp/raw/repo-ossIZFALm Verify the URI for this repository I've tried to reset the list of repositories with yast ("Online update configuration"), but I receive an error there to ("Query product failed" after I've checked "Configure Now" clicked on "Details...") Please could you help me ? Is there an official list of software repositories that I can either compare with mine, or manually configure ?

[opensuse] 11.0 All lights on on keyboard (not flashing) box still working but no kbd?
by David C. Rankin 28 Aug '08

28 Aug '08

Listmates, I just checked on an 11.0 box, tapped on the keyboard and nothing happened. Then looked closer at the keyboard and the scroll lock, numlock, and caplock lights are on steady. That was strange, because moments earlier I was working from a samba share on the box. A quick ssh into the box and check of the logs and all is good - no errors. What happened to the keyboard? I know flashing lights means hardware failure, what do steady lights mean? What to try to get the keyboard back? (we have a kitten, so a prior tap-dance on the keyboard isn't out of the question) -- David C. Rankin, J.D., P.E.
