Adaptec AIC7xxx chipset SCSI controller support
CONFIG_SCSI_AIC7XXX
This is support for the various aic7xxx based Adaptec SCSI
controllers. These include the 274x EISA cards; 284x VLB cards;
2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and
motherboard based SCSI controllers from Adaptec. It does not support
the AAA-13x RAID controllers from Adaptec, nor will it likely ever
support them. It does not support the 2920 cards from Adaptec that
use the Future Domain SCSI controller chip. For those cards, you
need the "Future Domain 16xx SCSI support" driver.
In general, if the controller is based on an Adaptec SCSI controller
chip from the aic777x series or the aic78xx series, this driver
should work. The only exception is the 7810 which is specifically
not supported (that's the RAID controller chip on the AAA-13x
cards).
Note that the AHA2920 SCSI host adapter is *not* supported by this
driver; choose "Future Domain 16xx SCSI support" instead if you have
one of those.
Information on the configuration options for this controller can be
found by checking the help file for each of the available
configuration options. You should read drivers/scsi/README.aic7xxx
at a minimum before contacting the maintainer with any questions.
The SCSI-HOWTO, available via FTP (user: anonymous) at
ftp://metalab.unc.edu/pub/Linux/docs/HOWTO can also be of great
help.
If you want to compile this driver as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read Documentation/modules.txt. The module will be
called aic7xxx.o.

Setup no, operation yes. I'd suggest that you only use RAID0 as the O/S
level, do anything else (RAID1, RAID5, RAID10) at the hardware level. If
the box is doing any heavy work, RAID1, 5, or 10 will suck up lots of CPU
and saturate the bus if you do it at the O/S level. Do it at the hardware
level instead.
There's an hardware adapter from 3ware.com that supports RAID0, RAID1, and
RAID10 for IDE drives, is certified to work with Linux, and only costs about
$150 for the 2-channel model. There's also an IDE RAID adapter from ABIT
(www.abit-usa.com) that's only about $50 for a 4 channel (!!!), their site
states that it is supported by Linux, but the manual doesn't mention it.
Anyone familiar with this?

Anyone familiar with this ABIT product or any other ABIT product? Their

the manual doesn't mention Linux, only Win9x and NT. Anyone using one of
these in a Linux box? I've heard that ABIT makes quite good stuff, and this
board supports RAID0, RAID1, and RAID10 with up to 4 IDE drives, and is less

Pull out the harddisk drive (when they have the same size or it may
bebigger if you would like to keep the partitions the same). Hang it in
the working machine and type: dd if=/dev/hda1 of=/dev/hda2 bs=1024k
now a block to block copy will be made creating 2 exact harddisk copies.
When it's done (can take pretty long when the disks become big) hang the
drive in the other machine and start. Now you still might need to
correct any X-Server settings and Network card settings if they aren't
the same.

This has nothing to do with telnetd problems.
When you wait long enough (about 30 seconds the prompt would show also).
The problem that you encouter is pretty simple to solve. Telnet and FTPd try to
reverse lookup a client by it's ip address. That can take up to 30 seconds when
the server times-out talking to the DNS server.
You can solve this by enterring the hostname and ip address of the clients that
telnet to your either in a DNS (also the reverssed zone) or in the /etc/hosts
file form your RedNeck box. If you have a DNS running please insert the host in
the DNS it has less administrative overhead.
But you sound new to all this (no harmfull thoughts here), so my guess is that
you don't have a DNS running yet.

LVM is a wonderful tool. Works flawlessly here. You must have the
2.4.0-testX kernel, or else, patches for
older kernels. I know nothing about the patches, as I am using 2.4.0-test7
here. Also, all the tools are in this package, available at www.rpmfind.net:
lvm-0.8-0.i386.rpm. There's a really good install and configure document
available at http://ds9a.nl/lvm-howto. That's what got me going with it.

What are you aiming at? You mean to find a fully threaded
rpc-portmapper?
I haven't seen any on FreeBSD or Linux yet. Besides a few hundred
requests are no problem.
A portmapper does'nt do much. It just negotiates a free port between the
client and "server". Now the client can send RPC requests to be runned
from the server.
Personally I hate RPC's I also don't know what your application does.

You could also install VNC server on your NT box and VNC on your Unix box
and take control over the console and reboot it.
I don't know if you know how to program, but you could make an easy C or
Perl Socket server that when you telnet to the box and type a password that
the services cals a system("shutdown /r /c /y"); You need to get the
shutdown command from a resource kit CD when it is a NT4.0 system and no
TerminalServer.

This depends on your MTA used.
In sendmail you edit the virtusertable or virtual-user to do the following (I
assume that you client has a domain but you can also do this on a per user
basis).
@domain.com [EMAIL PROTECTED]
What this does is queue all mail for domain.com untill the user on
mailserver.domain.com sends an ETRN
when he wants the mail deliverred or when the next queue run flushes the queue
all the mail for domain.com will be send to mailserver.domain.com like a
ESTMP/bSMTP solution providers offer.
For more details look at my site: http://www.phonax.com

Hoi Dick ik ga effies verder in het engels
You don't gain a conciderable amount of computation power. It stringle depends
on the applications that you decide to run, whether they are multi-threaded or
multiple forked process.
I have experimented a fair bit with SMP on Linux, FreeBSD and NT. I noticed
that applications that are not specifically written for SMP that they might run
slower on all 3 of these OS's. Apache is a very good example, Apache on Linux
SMP doesn;t gain anything much but doesn;t lose much either. On FreeBSD the
whole performance dropped 40 to 50%!!! On Apache and NT you did get a massive
amount of performance since Apache on NT is multi threaded.
I wrote some instruction parallel processes my self, and I noticed that on
FreeBSD it might speed up and on NT and Linux slow down. Due to the fact that
my L2 cache was bigger on the BSD box. than on the other 2. And the data that I
was processing was bigger than the ammount of L2 cache on the other 2 boxes,
stopping the CPU's to get to the memory controller and asking for the specific
data.
So you can write very good SMP aware applications but they still are pretty
selective due to the CPU's. Intel SMP is still some what of a childsplay. Don't
expect to much from your second CPU, specially not when you are a standard
server or desktop user. If you like to calculate massive itterations, than you
can write your own SMP software that will use your hardware to the best.
The example of the other guy with DB2 is a good example, that application has
some deeper knowledge of SMP knowing how to behave. But even that performance
gain can differ betwen 5 to 95% on a other CPU, BUS, SCSI adapters etc etc etc.

I have been configuring & testing software RAID for a couple weeks
now. Using RAID-1 (mirroring), performance and recoverability are
excellent. Using RAID-5 (though not for the /boot or / filesystems) I
am having a problem, if drive 0 is removed the system won't mount the
RAID-5 filesystem. Working on that with RedHat at the moment.
Someone advised not to use software RAID. As CPU speeds increase,
this advice is less and less valid. With a fast CPU, the performance
penalty of software RAID can sink below zero. Because the CPU may be
faster than the processor on a [hardware RAID] RAID controller, the
RAID controller's processor could actually become the system
bottleneck.
Two bits of advice:
1. After installing RAID, test it, by disconnecting drives ONE AT A
TIME, while the system is powered off.
2. You will notice that after a drive is removed and replaced, the
system does not immediately put it online. You must (a) partition the
drive identically to the drive that was replaced (obviously you don't
have to do this if you have just disconnected and reconnected the
drive as a test) and then (b) use 'raidhotadd' to add the drive back
into the RAID array.

FWIW, I use Lynx almost exclusively, tiring long ago of Netscape "features"

naturally respect the choice of others, but will not tolerate whining about
"buggy~ fluffware as long as browsers like Lynx do the mundane so well.
Lynx is *FAST* and robust, if yeoman browser duty fits your bill.
Java? Forgetaboutit... :)

An alternative: customize the global Lynx configuration file--usually
/etc/lynx.cfg
in the "Proxy variables" section. Don't forget "no_proxy" settings, if that
is required (for firewalls etc.).
I personally prefer having each user copy this global config file to their
own homespace (to allow a better localized customization) and then use the
local version via startup command line; i.e.;
lynx -cfg=~/lynx.cfg
(etc.).
You can look over additional options by starting Lynx in help mode:

I see your problem, many people build a firewall with the wrong principle in
mind, the DMZ firewall is no solution. SInce you need to subnet your small rang
104-to-107 in order to route them. Leaving not much over.
I never evr use the DMZ 1 firewall since it is weak and it leaves you with
hardly any IP address left.
I always use the following idea (the 2 firewall creating a perimiter network)
Inet---[router with packetfilter]------------------[second firewall doing
NAT fi]--------
|- peer ip (mostly auto. assigned by ISP)
| |
|
--internal net
|---- perimiternetwork 104-107
The second firewall/router can have more then 1 NIC if you'd like to connect
more than one physical network.
The NAT and more packetfiltering will secure your internal network against any
attacks from the outside.
The first routing firewall (I often use Cisco's because they are relaible for
99.9999%) and there you provide access lists for the so called bastion hosts
(webserver, mail server etc etc etc). This way you have a more secure network.
Specially when you use 2 different firewalls.
Personaly I don't understand were all those pictures of the single firewall
idea come from I see them in all the magazines but it is not the ideal
situation by far. The only thing that it is cheap, but security is less due to
the fact that you only have 1 firewall (with all it's known exploits) second of
all iy you want to secure your webservers, you need to route them unless you
have your firewall connected to the internet by a dialup network asswell.

For background:
How is your mouse cursor config'd in the XF86Config file - hardware or
software?
Check under your video display settings - what does it say? Do you see
"sw_cursor"?
