Thanks Norman, that article above solved the problem (downgraded the BIOS
to AO2). I'm not sure how I missed that one when I was googling though..

network performance tuning
by fedora
As I have mentioned before I am working on creating various Fedora
server loads at http://www.packetstorm.org/fedprj/
So far I have the core load done and I am almost done with the log
server load http://www.packetstorm.org/fedprj/core/log_server.htm
While looking into network performance tuning options, I ran across the
following setting tweaks that could be made on the system
net.ipv4.tcp_rmem = 10000000 10000000 10000000, sets min/default/max TCP
read buffer, default 4096 87380 174760
net.ipv4.tcp_wmem = 10000000 10000000 10000000, sets min/pressure/max
TCP write buffer, default 4096 16384 131072
net.ipv4.tcp_mem = 10000000 10000000 10000000, sets min/pressure/max TCP
buffer space, default 31744 32256 32768
net.ipv4.tcp_sack=0 turn SACK support off, default on
net.ipv4.tcp_window_scaling = 0, turn TCP window scaling support off,
default onnet.core.hot_list_length = 300000, maximum number of skb-heads
to be cached, default 128
net.ipv4.tcp_max_tw_buckets = 2000000, sets TCP time-wait buckets pool
size, default 180000
net.ipv4.tcp_timestamps=0 turns TCP timestamp support off, default on
net.core.rmem_max=524287 maximum receive socket buffer size
net.core.wmem_max=524287 maximum send socket buffer size
net.core.rmem_default=524287 default receive socket buffer size
net.core.wmem_default=524287 default send socket buffer size
net.core.optmem_max=524287 maximum amount of option memory buffers,
default 10240
net.core.netdev_max_backlog=300000 number of unprocessed input packets
before kernel starts dropping them, default 300
For the log server I focused on socket buffers as I noticed that udp
packets were getting dumped due to high syslog volume. But does anyone
here have a really good explanation on the settings above? Can they be
used as a general performance tweak on any system configuration? I read
in one place some of these settings should not be used on multi-user
systems.
Is there a Fedora tuning guide? Any recommendations for a good baseline?
Is there a reasoning behind the default Fedora settings listed above?
Not that I disagree but that I want to understand it.
FYI here is a SPEC doc I found in google where some of these settings
were mentioned

dulug.duke.edu mirror

Anyone else noticed that this rsync mirror isn't deleting packages when
it syncs with Fedora development? Seems to now have 2-4 versions of the
same package instead of deleting the older ones.

Fewer partitions are better (Re: Disk Layout/Partitioning Practices)
by Keith Lofstrom
Ron Herardian <rherardi(a)gssnet.com> writes:
> When installing everything and allowing for future updates and packages
> I am using the following disk layout:

It may be time to rethink multiple partitions. For legacy reasons,
I build my systems with multiple partitions, but if I had it to do
over again I would probably do it with 3 partitions:
/boot (because it has to be small)
swap (about 2 GB)
/ (everything else, including multiple drives if LVM)
For the average system, the swap probably should be smaller, but I
run huge, poorly designed CAD apps for days that tend to fill VM.
With RAM so damned cheap these days, I agree with other folks that
make swap a lot smaller than 2x physical RAM. Paging more than a
few hundred megabytes of swap is just too damned slow, regardless
of the amount of RAM that you happen to have in your system.
If I had a problem with users writing huge files that filled the disk,
I would put quotas on the individual users, not on their partition as
a whole. If anything goes wild, and fills up /, the system is in
trouble anyway, and repair time is not significantly improved by
limiting the fillup to one of many partitions. In fact, a lot of
problems happen because /tmp fills, or /var/mail fills and /var/log
doesn't work. I subscribe to the Andrew Carnegie maxim "Put all
your eggs in one basket - then WATCH THAT BASKET".
My past excuses for multiple partitions were: (1) limited disk sizes
and (2) managing backup tapes. Both are invalid now. With large
drives and LVM, there is no practical limit on partition sizes for
most systems. With disk-to-disk random access backup, there is no
need for complicated partition arrangements to fit data onto small,
slow tapes. I control backup frequencies and depth by directory,
not by partition.
On mild excuse for retaining multiple partitions is to minimize
boot time - if you are running a journalling file system, it will
occasionally delay booting for significant time to fsck one or two
of the partitions. But if you have a very large /home, the time
saved by peeling off a bunch of smaller partitions is not that
significant. There are probably better ways to schedule fsck.
I expect strong opinions differing from the above; no doubt I've
forgotten something. Newbies should keep following this thread and
see where I've erred. But a lot of the reasons we do things are
traditions that stem from past restrictions that no longer apply.
We should acknowledge these changes in our system designs.

Re: usb-storage

I have a similar problem with a Lexar Jumpdrive USB 2.0.
Before it runs, I have to add this command:
modprobe usb-storage
Then it works.

Yes, I did it, but it still shows the ip address and I went to the hostname
file in /etc, it showed AMD_FC1, is there anywhere else that I need to
change?
Thanks in advance for your comment/suggestion

If I change the hostname, will it cause problem when I connect to internet

provider, using their domain name, once I change it, will I still be able to
connect?

Link 2 computers thanks to a "crossed" network cable
by Coume - Lubox.com
Hello,
I have been using Fedora Core 1 since it came out, but there is still
one thing that I cannot manage to get working :(
I cannot manage to create a network between my linux laptop and another
computer under windows (or linux). It was working fine with Mandrake :(
I'm able to log onto the university network and then access the
Internet.
BUT if I connect my laptop directly to another computer thanks to a
"crossed" network cable, I cannot get the computers to "speak" together.
Is one of you managed to plug 2 computers like that??
Thanks in advance
Regards,
Ludovic
