Subject: Scanjet IIp, SANE & hpscanpbm
Date: Sun, 17 Sep 2000 14:27:05 -0500
I'm stuck. I'm trying to install a HP scanjet IIp on a RH6.0 machine,
kernel 2.2.16 with SCSI already enabled:
(scsi0) <Adaptec AHA-294X SCSI host adapter> found at PCI 0/20/0
(scsi0) Narrow Channel, SCSI ID=7, 16/255 SCBs
(scsi0) Downloading sequencer code... 416 instructions downloaded
scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 5.1.28/3.2.4
<Adaptec AHA-294X SCSI host adapter>
scsi : 1 host.
(scsi0:0:2:0) Synchronous at 5.0 Mbyte/sec, offset 8.
Vendor: IBM Model: HP35480A !C Rev: 9
Type: Sequential-Access ANSI SCSI revision: 02
Detected scsi tape st0 at scsi0, channel 0, id 2, lun 0
scsi : detected 1 SCSI tape total.
I started looking and asking a few weeks ago, have downloaded SANE
[rj@localhost sane]$ ls
sane-1.0.1-4.i386.rpm sane-1.0.1-4.src.rpm
and hpscanpbm-0.3a.tar.gz
Since I really didn't know where to start, I untarred hpscanpbm and
attempted to compile it according to the instructions in the source file
-- and immediately hit a brick wall.
[rj@localhost hpscan]$ cc hpscanpbm.c -o hpscanpbm
hpscanpbm.c:169: /usr/src/linux/drivers/scsi/sg.h: No such file or
directory
Sure enough, there isn't a file named 'sg.h'. I looked in my original
source for kernel 2.2.5 and the file isn't there, either. Where do I go
from here? Will some kind of magic be worked if I go ahead and install
the SANE rpm? Am I going to have to drop back and recompile my kernel?
As should be obvious to the most casual observer, I am thoroughly
confused at this point.
Thanks in advance for giving me a shove in the right direction!

Hello,
I've had an accident which damaged a part of my hard disk.
Fortunately I can still boot Linux and use the apps there, but I also have a
vfat partition with Windoze (that I need sometimes) and it can't boot. It
freezes everytime it tries to read some of the damaged data.
I've tried to use DOS bootdisk with Norton disk doctor, but it freezed too.
Is there some "disk doctor" for Linux?? I really need it, because Linux is
the only OS I have, that doesn't crash when using the damaged disk.
Thanks

I've used netscape 4.7x to download the oracle 8.1 distr of 384 megs that
is just 1 file; so, large file download is ok. Also have just downloaded
the msoffice service pack that is 52+ megs. Both downloads were done
in SuSE. Also have used ncftp to get 20+ meg filesizes without problems
while in linux.
Your "problem" may be just the max users for the site or when "everyone"
is downloading the everything. What "speed" is your access...

Hi
AFAIK, you need to excecute the file

perhaps you need to do a chmod +x

Could you be more specific about that? The last time I checked the
ext2 code, it merely had the same limitation as VFS + LIBC.
I expect Alexander Viro can comment on this more competently than
anyone else, as VFS is basically "his baby."
For those that don't want to go through those details should
take a look at /usr/include/stdio.h, particularly at the
call signature for fseek(stream, long int offset, int whence).
File sizes are limited by the fact that on 32 bit platforms, a
"long int" is normally 32 bits long.
And cacheing doesn't work out too well if you can't map files onto
virtual memory.

Subject: can't connect to napster
Reply-To: [EMAIL PROTECTED]
Date: Sun, 17 Sep 2000 20:50:27 GMT
Hello:
I run IP masqerading on a Linux box to share a cable modem with my
roommate. He's running Win98 on his computer and can use Napster without
any problems (connects okay, downloads fine, etc).
I used to use the gtk-napster client version 0.201 until it started to
consistently time out on every connection attempt. I figured it was the
software and upgraded to v0.301. Here I selected "autoget best server"
from the connect screen, and it returns a "Warning -- connection refused"
back on the terminal from which I started gtk-napster.
I tried some other clients and had similar problems:
- with TekNap I get these results:
Attempting to get host from 12.18.122.252:8888.
Connected. Attempting Login to 12.18.122.252:8888.
blah!* banned: do not unban
do_server() Connection closed from 12.18.122.252: Remote end closed
connection
- with nap-1.4.4 I get stuff such as this:
Getting best host...
Connecting...
Error connecting socket
Getting best host...
Connecting...
Error connecting socket
- I also tried the client lopster-0.9.3, it just times out on
connections to the "Official Server" while searching for the best
server.
For a while I thought that my IP was banned somehow---but if my roommate
connects okay, that certainly isn't the case. Also I thought my username
was banned, but I also tried connecting with my roommate's password, and
that didn't work either. Also I thought my IP masquerading setup was in
error, but again, if my roommate's works okay, shouldn't mine?
Anyone have any ideas? I am just missing something obvious here?
Thanks,
Matt

What I am saying is that a "Paranoid" security mode is fine for
beginners, however one should truly ~LEARN~ how to harden a machine
from ~SCRATCH~. I have never found it particularly benificial to
depend on any particular vendor (save OpenBSD) for security issues.
It is good that Mandrake simplifies the operation, but ultimately I
would not feel secure until I had done the usual patching, plugging,
checking, etc... (inetd.conf, rc.d dirs, SUID scans, tripwire, etc..).

First, if someone cracks your machine, ~STOP~, do not pass go do not
collect $200 US. ~YOU HAVE LOST CONTROL~, there is only one sure way
to get it back. Remove your network connection, halt your machine, wipe
the disk, and reinstall. Even restoring from backup at this point
poses an extreme risk, I would not, but if your information is that
important, restore, but be careful. While your machine is down, and
before you reconnect to any network, read all you can on hardening a
machine, then put that knowledge to good use. Get the most UNIX savvy
person you know to attempt to break in. After you have carefully
assessed the security of your host, and are ~SURE~ that it is OK,
return it to its normal duties.
Now, to anwer you question "Does a cracker install software on your server?"
Yes a cracker does all that. Think of the force, there is a dark side
to the force, those who belong to the dark side are crackers, those who
belong to the good side are hackers. Most of the people who are
hackers (you are not a hacker until another hacker calls you one) will
be quite upset at the flagrant misuse of the term. It takes much
effort to become a hacker, to see other script kiddies who break into
machines for kicks called hackers is simply wrong.
The above is an over-simplification of reality. For a more in depth
discussion of the subject read Eric S. Raymond's _The Cathedral and
the Bazaar_. It is good reading anyway.
All the Best!

Actually I find the tragedy of the Kursk to be an extreme horror of the
consequences of war. Though actual war was not the direct cause of it's
sinking it was a vessel of war none the less.
I also find the movie "The Day After" which tells of the tragedy of the
consequences of war. But I also respect the fact that if a nuclear war
were to ever be as severe as in the movie we won't have to worry about
what to fight World War IV with.
Sticks and stones will be plentiful if we are still here to fight.
