In bash, you need the -e option to echo for it to process \-escapes,
like: echo -e 'hello\012there'

I looked for a Visio-like application for Linux about six months ago and
it seems like there was something in release or about to be released, but
I don't know if it was file compatable with Windoze Visio. I got
sidetracked and never chased it down. If you find something, post it here.

Reply-To: [EMAIL PROTECTED]
Hi,
I've run up on a "cute" problem with receiving scsi bus resets under
heavy load.
Please help me or give me a hint at least how to solve the followng
cutie :(
Actually the error is :
============
Aug 22 13:25:30 perun kernel: scsi : aborting command due to timeout :
pid 269474, scsi0, channel 0, id 0, lun 0 Write (10) 00 01 0e 1a 98 00

00 80 00
Aug 22 13:25:31 perun kernel: SCSI host 0 abort (pid 269475) timed out -
resetting
Aug 22 13:25:31 perun kernel: SCSI bus is being reset for host 0 channel
0.
Aug 22 13:25:34 perun kernel: (scsi0:0:0:0) Synchronous at 40.0
Mbyte/sec, offset 16.
============ from /var/log/messages
It is definitely not a problem with a specific kernel as I the error
persists on kernels 2.2.14-16 with several different aic7xxx patches.
It's not a distro error either both RH and Debian were tested, if anyone
starts doubting about this.
the error is received during the following test script:
-- test script --------
#!/bin/bash
/opt/home/tiobench-0.3.1/tiobench.pl --dir /group --block 2048 --block
204800 --threads 1 --threads 100 --threads 200 --size 1500
2>spectrum.err | tee spectrum.log
==========
the exact location is on the 204800B block size with 1 thread run.
Ok. I understand that ithis is overkill, but I need a robust system -
so this is part of the testing process.
Since I don't have the sufficient knowledge and information to start
tampering with the scsi codes/erorrs and I don't have a similar
hardware to run equivalent tests on it I can't identify the source of
the error :
- kernel/aic7xxx driver bug ?
- hardware (scsi controller) error ?
- cabling error sources are eliminated by several ( 5 ) tests with
different cables, overall bus length is under 2m.
- the "HD" error /buggy firmware chance is quite low - this is a
second box of this type I'm testing (with different firmware vers.
though )
Hardware details
============
Motherboard - ASUS P2B-DS SCPI Rev1012
Award bios v4.51p6
with onboard Adaptec 7890 bios v.2.11
"HD" - ZERO-D 400 IDE-RAID system, firmware v.2.2W
Thanks,
Vlado

Just what do you mean by that? It sound like a lot of empty talk devoid of

Speak of your desires and do not attribute them to others. Still I ask,
what does that have to do with software installation procedures?
By the way, do you know what it means to program a station? I don't think
you do, or else you would not have used, "the station I programmed on the
Internet", since it does not belong in this discussion.
> We can't do all of this by coping all our files onto our bin directory.
I never mentioned anythng about copying anything into bin. I never even
mentioned bin. Further, I would never suggest putting ALL our files into
bin let alone onto bin. The installation method has nothing to do with what
the software can do once it is installed.
You are begining to sound like a person how has come up with a half baked
idea to solve a problem that does not exist and is now trying to convince
others that they have a problem so that your can sell them your solution for
it. Yes sir you have trouble right here in River City!

For some devices the data is stored as numbered fixed length blocks. For
other devices it is not even that structured, just a continuious stream of
bytes or bits.

Without the abstrations the the OSs impose on DASDs (Since that is the type
of storage devices that seem to concern you), your would have to be deal
with fixed size records where one record is one sector. You would have to
determine into which sectors to place you data. You would then have to
refer the the files by the address of the first sector and the number of
sectors you have set aside for it. If the file out grows that space you
have allocated for it, you would have to allocate an additional extent for
it then your programs would have to be informed and account of the multiple
extents when processing the file. Is that what you are really proposing?
That is what your wording would call for.

Thank you for supporting my position.

You seem to care, for some strange reason.

There you go again! While all programs can be stored on disk as data, not
all data are programs. You seems to be suggesting again that you idea of
structured data can some how replace programs. And that the programs should
be platform independent at the executable level. I do hope you are
experience enough to see the fault in that logic and so why that can not be.

Oxymoron.

I have made no such claims.

Do you realize ehat "the storage level" means? That is at the hardware
level. At the hardware level that are no files, directories, or attributes;
there are only way of encoding bits or bytes which are (in the case of
DASD's) offered to the system in the form of fixed length blocks named
sectors.

Oxymoron!

Pardon?

Again, thank you for supporting my position.

Does Solaris use Microsoft Windows terminology that you have used in this
thread? If any of us have made a error as the the platforms you are used to
using, it is as a result of the terminology that you have selected to use to
present your ideas.

Technologies that already exist, assuming that the latest permutation of
your position is what you are really proposing.
The are many things that don't map well or at all from one OS to another.
How would you handle those details?
Consider file and directory attributes and permission settings. They don't
map from one OS to another very well. The installation process needs to be
OS specific in this and in many other areas.

Use the -e option to echo, to enable escape sequence interpretation.
echo -e hello"\012"there
In the bash man page, you want to look in the section titled
SHELL BUILTIN COMMANDS for a description of echo and its
options. You can find that easily while using the man command
by doing a search. At the prompt, type in /echo and hit return.

Red Hat's Powertools (which is on the ftp sites) has C-Kermit. Powertools
seems to be a grab bag of open source stuff that didn't make it into the
distro and "free beer" stuff that can't be distributed on CD.
Red Hat's pinstripe beta has gkermit, but this version does not make
connections!:
G-Kermit is a UNIX program for transferring files using the Kermit
protocol. Kermit is a file transfer protocol for transferring text and
binary files without errors between diverse types of computers and over
potentially hostile communication links.
G-Kermit features include: support for text and binary file transfer on
both 7-bit and 8-bit connections; files can be transferred singly or in
groups; automatic startup configuration via the GKERMIT environment
variable; and configurability as an external protocol.
Kermit protocol features include: automatic peer recognition, streaming on
reliable connections; selectable packet length from 40 to 9000 bytes (4000
is the default); single shifts for 8-bit data on 7-bit connections;
control-character prefixing for control-character transparency;
control-character unprefixing for increased speed (incoming only);
compression of repeated bytes; and per-file and batch cancellation.
G-Kermit does not support the following features: making connections:
character-set translation; interactive commands and scripting; and file
date-time stamps.

aloha!
i have a partition that i want to be able to mount
(r/w +reliably) both under linux/2.2.16 and freebsd/4.1release.
its all on the same computer and the same IDE disk.
which filesystem-type should i choose?
the puter is a so-called leafnode used by only me
(almost no longer newbie).
that partition will just be mounted occasionally, to store
some user- and configfiles, and to (reliably) move data between
freebsd and linux.
current config:
hda1: fat32, 5gig
hda2: ext2fs, 3gig (/ +swap)
hda3: ufs, 3gig (/ +swap)
hda4: ?, 1gig
ufs isnt reliably written to under linux (i got some errors,
not good...).
i heard ext2fs has new features that freebsd dont
recognize, is that true? (slack7.1 made my ext2fs)
fat32 doesnt preserve fileattributes...
nfs? setting up servers and clients and such, isnt
that too much hassle for my usage?
is there some ideal answer?
thanks for any ideas / alex k
