[rtl] Virus and spam emails
We are working on solving the problem. We have denied email submission from several of the originating sites but there are a lot of them. We do use DNS RBL blacklist rejection of open-relays and reject email from known spam sites with explicit rules. Spam email is not as simple as it was 6 months ago. Blocking solutions are slow to keep up and sendmail is even slower. The problem will be solved. In the meantime, I ask for patience while we work on it. -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl Your_email" | mail [EMAIL PROTECTED] -- For more information on Real-Time Linux see: http://www.rtlinux.org/rtlinux/
[rtl] PROBLEM WITH HAUPPAGE BOARD AND RTLINUX
Prof. Barabanov, I have a problem about RTLinux that I asked by maillist but nobody one has been able to help me to solve it. You are my last possibiliy. I have a PC with two kernel, the first the 2.2.17 , the default RedHat distribution , and the last compiled for RTLinux ( 2.2.18 + RTL3.0 ) . I have a real time application for the control a magnetic levitator . This application is a remote application . In order to allow the user to watch "as life" through his own computer I installed an Haupage board ( Bt878 ) that by the VIC ( videoconference ) application allows the vision When I use the board with the 2.2.17 kernel the video conference is possible, but when I use the same board ( I try with two Bt878 board ) something is wrong and the vision is impossible. I tried to change the interrupt, to verify the possible I/O conflits, I even tried to change the board but until now nothing t o do. ! Are you able to help me to understand what is happening, why the Hauppage board does not work under RTLinux ? Thank you for your help .

(I'm assuming the problem is that you can't run 'insmod' directly from the PHP server, as that would require the latter to have root permissions - which would not be a very good idea...) How about executing 'modprobe rtl_app_modules' or something like that? You'd have to edit the modules.conf for modprobe to define which actual modules 'rtl_app_modules' should represent. Other possibilities might be running a shell script with su root, or start it via sudo. The advantages of these methods is that you have a lot more control than if you'd trust PHP with permission to use insmod directly. //David .- M A I A -. | Multimedia Application Integration Architecture | | A Free/Open Source Plugin API for Professional Multimedia | `-- http://www.linuxaudiodev.com/maia -' .- David Olofson ---. | Audio Hacker - Open Source Advocate - Singer - Songwriter | `-- [EMAIL PROTECTED] -' -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl Your_email" | mail [EMAIL PROTECTED] -- For more information on Real-Time Linux see: http://www.rtlinux.org/rtlinux/

You're just not going to get away with writing to write protected memory

RE: [rtl] print_rtl during remote login
I borrowed a piece of code a while back and here is one thing that I saw.
printk("0my message here\n");
I changed it to
rtl_printf("0my message here\n:);
and in both cases the message was broadcast to all open windows and also logged to be
viewed by dmesg.
I do not know how this performs when remotely logged in.
I don't know why this works this way but it could be useful.

Hi Siva,
Typing dmesg at the remote terminal does allow viewing of the kernel ring
buffer on the other machine. It does what I want, although it would be
nice if you didn't have to type dmesg all the time. Probably the only
other way to get the print messages out of the rtl module is through a
fifo?
Thanks very much

RE: [rtl] print_rtl during remote login
Yes, "0my message here\n" really works. It gets printed on the remote
terminal as well. However, it does have a side effect. The speaker beeps
with each line of output and inserts another line "Message from
syslog@mymachine at Thu Apr 5 01:04:30 2001 ..." between each line of
output. It looks (and sounds) like one of those broadcast messages that
operators send to users before shutting down.
Nevertheless, it does work, and I might just disable my speaker. I have
not yet tried Eric Peterson's suggestion (man klogd(8)). I am indeed
grateful for all the responses on this question.

[rtl] Blocking read from FIFO in Linux app?
I installed RTLinux 3.0 on Kernel 2.2.18 on a dual processor PIII 500MHz. All I
need is a 60Hz signal to a Linux app. I originally tried modifying the Kernel Hz
from 100 to 960 but for some reason there were a tremendous amount of jitter
whereas 100Hz was fairly stable.
For my second attempt, I installed RTL 3.0 and cobbled up a pair of programs
from the examples. In my test program everything is fine and the jitter is quite
low no matter what I try to peturb it. When I try to use the read in a large Ada
program it works for a while and then I start getting zero bytes back from the
FIFO sometimes instead of blocking until the FIFO is non empty. I put in code to
read the FIFO again if the read returns zero bytes but instead of blocking on
the FIFO my CPU utilization is 100%.
I like having the FIFO return a structure which is the tic count and the elapsed
time from the RDTSC instruction because it allows me to detect frame overruns
but I could use a semaphore if anyone has a reliable example.
