Hi,
|
|
|
|
I am thinking of purchasing a 9GB seagate drive (Elite 9) for use with
|
|
Linux.
|
|
|
|
Does anyone know if this would cause a problem?
|
|
|
|
Anyone out there using big drives with Linux and regretting it?
|
|
|
|
|
|
All answers would be greatly appreciated.

um, not really, since most 486dx2/66 motherboards are in to $2-300 range,

Subject: ftape works!!

|
Date: 23 Sep 1994 15:00:56 GMT
|
|
|
|
I finally have ftape working reliably with my colorado 250! Since I
|
|
started using the newer kernels, I have had a problem with it getting
|
|
stuck in a loop whenever it found an error on the tape. :< I am using the
|
|
latest ftape, ftape-1.13b, and I have used every kernel to try to get it
|
|
to work. It would write fine, but when I would read it back to verify
|
|
it, about 100 megs into it, it would get an error and back up and read
|
|
again. It would just keep doing this untill I killed the process. I
|
|
knew it was not the tape or drive, because it workes fine under dos.
|
|
|
|
To get it to work, all I had to do was increase the buffers in the kernel
|
|
to 10. It takes a little bit of memory ( I only have 8 megs ), but it
|
|
works. I have created a 240 meg (two tapes) backup of compressed data,
|
|
verified it and repeated this several time. I have not had it loop
|
|
once. I also upgraded to 1.1.51 at the same time, but I don't think that
|
|
did anything for my problem.
|
|
|
|
I am posting this, because I have heard of other people having the same
|
|
problem. I hope that this trick will help some other sould out there...

Wouldn't using 64-bit REAL numbers provide exact integers of at least

If so, you wouldn't need any software conversion routines.

I'm trying to install Linux on my new PC. But somehow Linux has a problem

My 2nd linux HD thus also uses the LBA setting and has the same problem.

The X documentation recommends a minimum of 16Mb memory (combination of

|
RAM plus swap space) to run well. I understand that Emacs is also a

|
memory hog, and I expect that LaTeX is similar, so you probably want to

Uhmmm... I hate to burst your bubble, but simply "not developing" this tool

access to the system, I can probably boot any OS I want. I can also access

ANY disk on the system. So the system is INHERENTLY insecure. A much better

security precaution is to not put any files on the system that you don't want

|
damaged/stolen/viewed/etc.
|
|
|
|
Besides, if someone is _truly_ devious, _THEY_ will develop the tool
|
|
themselves. I say we should develop a tool that requires a password to
|
|
access the Linux filesystems. Certainly no more secure than the current

system, but it will make some people feel better about themselves (and it

could keep my 4yo kid from trashing my Linux fs...)

Pardon my ignorance...
|

A bit ago I went to a class at Hewlett-Packard and the instructor said that
|
|
on Unix fragmentation was actually a benefit, or not as much of a deterrent as
|
|
on DOS. The reason was since you have a multi-user system that will probably
|
|
be accessing all sorts of files all over the place, the fragmentation helps
|
|
out.

anyone?

IT IS ALL MY FAULT - DON'T BLAME LINUX!
|
|
|
|
Confessions of Network Administator:
|
|
|
|
I did 3 things wrong that caused all my problems with PPP and IP Forwarding:
|
|
|
|
1. DNS/BIND mismatch between my primary server, and my providers server
|
|
My Internet Provider runs a secondary name server for my domain, and I
|
|
made changes to my primary DNS tables (including re-assigning the IP of my DOS
|
|
box)... BUT I FORGOT TO CHANGE THE SERIAL NUMBER IN THE DNS TABLES. The serial
|
|
number is how secondary servers determine that DNS needs to update... So the
|
|
two servers had different IP addresses for the same host name... OOOPPPS!
|
|
|
|
2. DOS TCPIP Routing MisConfiguration
|
|
Netmanage Chameleon has two separate configurations for routing... the
|
|
Default Route, and a Routing Table... I had set up an entry in the routing
|
|
table for my Net Provider that pointed to a router that was available on the
|
|
old network that I was connected to.. and that entry over-rode the Default
|
|
Route that pointed to the correct router (took me 4 days to find that one)
|
|
|
|
3. Gratituously updating Linux versions
|
|
My initial response to this problem was to blame Linux 1.0 and to
|
|
attempt to install a later rev of the system (1.1.49 to be exact). This
|
|
ofcourse created all sorts of additional problems requiring the installation of
|
|
updated applications and utilities, which I thouroughly botched in my haste to
|
|
get the system working as a router.... Since I found the other problems, and
|
|
did a complete re-install of 1.0.... everything has worked fine...
|
|
|
|
Advice to the Wannabe Network Administrator:
|
|
|
|
Erasing and application and doing a clean install may not be a bad
|
|
idea. All of the configuration may look right.. but some leftover trash may be
|
|
spoiling your whole day.
|
|
|
|
Request to the Linux Developers:
|
|
|
|
I had a *ell of a time figuring out what patches and utilities went
|
|
together to make a fully updated version of the system... Grouping the Patch
|
|
files with the utilities required to accomodate the update would really help.
|
|
|
|
Other than that... KUDOS TO YOU ALL... Linux is the best system I've
|
|
worked with since I started working with MicroPort and Venix 6 years ago.. It
|
|
certainly beats even the latest release of UnixWare in terms of ease of
|
|
installation and loads of applications and utilities right outa the box...
|
|
|
|
Before I shoot myself in the foot again.....

|
|
The AC3200 driver is for the Ansel Communications EISA ethercard based on a
|
|
shared memory 8390.
|
|
|
|
It's unrelated to the NE3200, which will probably never have a Linux driver.
|
|
|
|
Both are unrelated to the Intel EtherExpress32. I don't have any
|
|
documentation on the EE32 (or an EISA machine to develop a driver on), but
|
|
Intel might release it if you ask them.
