I overclocked my PII 266 to 300 and upped the bus speed to 75 mhz. Now
when I boot Linux turns off DMA on my hard drives. Is this bad? What
does DMA do anyway?
By the way I am on 2.2.0-final (aka 2.2.0-pre9)

I have been developing application for DOS and Windows for many years
now, and have gotten bored with it, so I switched to Linux.
I have installed Red Hat 5.2 and have managed to set up the AfterStep X
environment with WindowMaker ( I think ).
Why isn't there a decent IDE to go with this beautiful Front End !

Hi all,
Just came across these sites that are useful for FOrtran90 and
Ratfor people. There are free Fortran to Java converters, Fortran90 and
Ratfor 90 compilers plus other stuff. Of interest is the free parallelization
Fortran library at www.linpac.ac.uk but this site must have moved since
the URL can't be found anymore; anybody know where it went?
Overall Fortran site stuff with links to the others mentioned below,
http://www.fortran.com/fortran and select free s/w
Free Fortran90 for x86 Linux and multiple parallelization fortran etc.

Subject: Kernel 2.2.0-final, broadcasts, am I the only one?
Date: 26 Jan 1999 09:33:11 GMT
hello,
since I run any of the existing 2.2 kernel, under my SuSE 6.0 Linux
system I have problems since no ethernet broadcast seems to reach any of
the other machines on our LAN. E.G ping <ip broadcast address> results
only in my machine answering. Snooping the network on another machine
shows no broadcasts coming from my linux box.
Everything else as far as networking is concerned runs just fine (e.g.
mounting NFS file systems, pinging a particular host, etc).
Booting a 2.0.36 kernel the answer to a ping <ip broadcast adress> is a
large list of all the machines on our LAN just as expected.
I posted this already some weeks ago, but received no reply. So am I
really the only one. Does anyone with a SuSE 6.0 system running a 2.2.x
kernel not have this problem ????
Thanks
Rainer

See the Linux <-> Windows HOWTO.
You can initialise any card in Dos/Windows and then use a batch file to
start Linux.
In short:
Copy LoadLin.exe and the kernel "vmlinuz" to your DOS/Windows
enviroment.
Make a batch file with the following contents:
loadlin.exe vmlinuz root=<linux boot>
for my system it is:
e:\linux\loadlin.exe e:\linux\vmlinuz root=/dev/hdb8
(I am using Red Hat 5.2, kernel 2.0.37)

I got exactly this error trying to build tonight. I compiled
2.2.0-pre8 w/o problem, but using the same config I tried the new
2.2.0 and I got the linker error at the same place.
However, I did not use the same config file, I remade mine from
scratch -- twice, to make sure that the first time wasn't a fluke.
AMD K6-233, using the "Pentium/K6" definition, if that matters.

Pointer freezing happens when the X server stops listening to what is
going on around it. This happens when the server gets swapped out, if
the server isn't getting any CPU time, if the server is loading
complex fonts, or if some application has a server-grab (that might
not affect pointer movement; it depends on the precise nature of the
implementation.) Kernel mods might have an effect on the first two
possibilities, but the last two are user/application-domain problems.
Swapping are my best bet for a cause of pointer-lockup.
If the pointer was a hardware-pointer it might be possible to do
something to alleviate the responsiveness problems (separate
thread/process that only handles cursor interactions, and that
communicates with the rest of the X server via shared memory in order
to prevent lockups over pipes... Or something like that.)

That is a new and fancy film scanner. I haven't gotten up the time or
the guts to actually obtain the device. I got technical specs from
Nikon, but they don't seem to be LS-2000 specific. Are you sure it
can't be driven with the LS-1000 drivers?

trust me, it's a feature, not a bug =) having a collection of machines
that answer to a broadcast ping is an excellent way to run an attack (smurf
attack, specifically).

Works fine on my boxes. Have you compared the broadcast address
you are using against the netmasks reported by ifconfig?

Yes they are correct. The strange thing is, that exacly the same machine
with exacly the same network configuration does not show this problem
when simply booting a 2.0.36 kernel (which does not affect things like
netmask or broadcast adress).
I also tried two different network adapters (Intel Etherexpress 100 and
a DEC Tulip based card). Both work, but without broadcasts.
Did you do anything particular after the base installation? What network
card do you use ?
Thanks Rainer

Subject: Help: Socket limits in Linux, Blackdown JDK 1.1.x
Date: Tue, 26 Jan 1999 11:19:42 -0500
I know this this has been discussed over and over but there seem to be no
real solution for this problem. Here's the problem:
I am developing a client/server chat application that requires at least 2048
simultaneous socket connections. The server portion is running on Linux
2.3.4 using blackdown's JDK 1.1.7. Somehow after reaching about 500
connections, the whole application fails.
I have attempted recompiling the kernel and updating OPEN_MAX, FD_SETSIZE
and NR_OPEN to 2048 - this causes a core dump when a 600 sockets connections
are established.
I've inserted the following in the rc.sysinit file and that did absolutely
nothing:
echo 16384 >/proc/sys/kernel/file-max
echo 32768 >/proc/sys/kernel/inode-max
What is the solution to this problem if any? Who do I need to contact to
resolve this issue? Is there a tested solution that someone can recommend.
