I checked the website; it has nothing relating to the problem I'm

I installed RH7 from the "respin" cd's (downloaded and burned), and
installed on the last 3 gigs of my 30 gig hard drive.
Installed LILO to the mbr but LILO doesnt show up. So now how should I go
about making a bootdisk to get into my Linux system?
thanks in advance to any replies

Subject: Sound problems with kernel 2.4.0
Date: Fri, 12 Jan 2001 14:45:47 -0600
I've upgraded my kernel to 2.4.0 and now I can't get my soundcard
working.
Here's the situation:
Soundcard: Creative Soundblaster AWE64 Value
Kernel configuration for sound:
# Sound (From my saved config file, all snipped lines are commented
out)
#
CONFIG_SOUND=m
<snippage>
CONFIG_SOUND_OSS=m
CONFIG_SOUND_TRACEINIT=y
CONFIG_SOUND_DMAP=y
<more snippage>
CONFIG_SOUND_SB=m
CONFIG_SOUND_AWE32_SYNTH=m
<snip the rest>
Everything built okay. I generated the appropriate (I thought) lines
for modules.conf using Red Hat's sndconfig program from the 6.0
distribution after I found a way around the "couldn't find soundcore.o
problem and fixed it.
(For anybody who's searching Deja for a fix for this,
cd /lib/modules/2.4.0
ln -s ../kernel/drivers/sound misc
)
The appropriate lines from /etc/modules.conf read as follows:
# load the sound modules
alias sound sb
alias char-major-14 sb # I tried this this line to see if it would
help after pouring over the
#
/usr/src/linux-2.4.0/Documentation/sound docs
pre-install sound insmod sound dmabuf=1
options opl3 io=0x388
alias midi awe_wave
post-install awe_wave /bin/sfxload /etc/midi/GU11-ROM.SF2
options sb io=0x220 irq=5 dma=1 dma16=5 mpu_io=0x330
and the "options sb ... " line is correct, according to "pnpdump
--dumpregs".
Now for the symptoms:
Every time I try to play a .wav file, two errors show up in
/var/log/messages. They are:
modprobe: Can't locate module sound-slot-0
modprobe: Can't locate module sound-service-0-3
I feel reasonably sure that I could fix this with an alias in
/etc/modules.conf, but I can't seem to find any clarification in any of
the sound docs, which, incidentally, don't seem to have been updated
since kernel 2.1 development.
Any help anyone can give with this will be greatly appreciated.
Regards,
ninewands

Indeed, I see no evidence of an L2 cache. The results are roughly consistent with
there
not being one. I'm not prepared to go into a second order analysis!
By the way, I have an old P100 on which the results are flat at 20MB/s as far as the
eye
can see. I suspect it has a broken mobo cache.

You'd have to graph it to see if the slope changes here. You might have a read cache.

It tells you at least what percentage of your write falls in the L1 cache!
You need to look at the first and second derivative to learn more.

Date: Fri, 12 Jan 2001 21:00:54 GMT
Hi,
I installed a Linux ADSL-Router with Masquerading and the
Suse-Firewall. It rather works fine, except two strange problems:
1.) I can access most websites, but there are a few I cannot access at
all, e. g. www.consors.de and I don�t understand what�s the difference
to "normal" websites? I can ping to the site, no problem. Netsace
won�t show the site at all. It searches to death!
2.) A normal traceroute to certain sites (e. g. www.consors.de) in the
internal net works fine. But on the router itself I get response for
about 5-7 hops an then timeout. I have no explanation for this. ping
works fine!
Has anyone an idea?
Thx,
Peter

Unless they have changed the install setup you can use the rescue choice
when you get to the boot prompt during the install and get back into the
system by entering:
rescue root=/dev/hdaX # hdaX being the root partition
Then use "mkbootdisk --device /dev/fd0 x.x.xx"
# where x.x.xx is the kernel version.

I need to expand my /usr directory a little and want to take some space from

need to destroy my existing partitions for the larger one? I was going to
make a .tar backup of /usr and repartition then recopy back the data. Is
there a better way?

Propabily you are using ipchains to make Masquerading/Firewalling. With
ipchains you can test "the cicle of live" of a packet.
You can try to test a packege with "source ip" yourself and "destination ip"
www.consors.de's IP. Then ipchains show the reason of packet's death.
I don't remember the flag to use ipchains as tester, i can't see manual now.
Sorry.

Well, I don't have a multi-GB database to back up each night. It's hard

For "astute beginner", Using RedHat Linux from Que (includes 6.2 CD)--if
you're not opposed to using RedHat. Rather complete and well done.
Also well done, (and based on RedHat), is Linux Network Servers from
Sybex. Covers general Sys Admin in addition to being network-oriented.

Actually, now I look closer, there is evidence for a 32KB cache, and then
a 512KB or a 1MB one. It may be that your cache is not all of it set up to
cache writes (writeback? writethru?)

Here it's clear that on read there is a 64KB cache.

I meant to say: a cache that works for reading but doesn't do a lot on writing .. i.e.
it
goes through synchronously on write. Writethru?

Hi!
How can I profile memory usage of my program, i.e.
the maximum amount of memory used and whether it deallocated all
dynamically allocated memory at the end?
Thank you.
