I've read that you can safely delete "core" files (aka core dumps) if you're
not going to do any debugging. Is the file "kcore" one of these "core"
files? (ie kcore=core)

Did you change your shell? This is one of the more common reasons
for suddenly not being able to ftp in.
It depends on what ftpd you're using, of course, but 'man ftpd' on my system
lists 3 relevant conditions that must be satisfied for ftp access:
-you must be in /etc/passwd and you must not have a null password
-you must _not_ be in /etc/ftpusers
-your shell must be OK according to getusershell (which effectively means
it has to be in /etc/shells)

I am running the 2.2.16 kernel with Gnome and I can't seem to get my
PalmPilot to sync all the components with the Gnome desktop (e.g.
Calendar, Address Book,...). The sync log shows that the first object
synchronizes and then the conduit seems to break. Anyone heard of this?
BTW, I am running this on an IBM Thinkpad 390X.
Many thanks

No. /proc/kcore is a phantom file, dynamically mapped to the kernel
memory. In other words, you shouldn't try to delete it, even if the
system would let you.

Subject: mkisofs -graft-points / multisession syntax
Date: Mon, 02 Apr 2001 10:06:01 -0500
Hello all,
I am a relative newbie at using mkisofs/cdrecord to burn CDs, and I am
having some trouble getting mkisofs to do what I want it to do. I am
setting up a script to automate multisession writes to CDR, based on
information found in a particular directory. What I would like to do is
to write each session to a separate directory under the root of the CD.
My preference would be to create the directory names on the fly,
grafting them into the existing iso and then filling them with the
information from the directory I want to back up. I have not been
successful in doing this. I have also tried creating the iso with a
number of subdirectories. When the directory /backup contains several
[empty] directories, the following has been successful in writing those
directories:
mkisofs -R -o [path]/isoimage.raw /backup
cdrecord -v speed=2 dev=0,1,0 -eject -multi [path]/isoimage.raw
Next, I tried to graft the backup files into one of the subdirectories
of /backup:
mkisofs -v-o [path]/$isoname -r -C $session -M 0,1,0 -graft-points
backup/$backname/*=/tmp/backup
cdrecord -v speed=2 dev=0,1,0 -eject -multi [path]/isoname
where $isoname is a unique name for the iso image, $session is the
output of cdrecord -msinfo -dev=0,1,0 and $backname is the name of the
subdirectory of the original iso image. The above cdrecord command
appears (from the report from cdrecord) to write the data in /tmp/backup
to the CD, but that data is not visible either in the $backname
subdirectory or in the root of the CD. I have also tried
mkisofs -v -o [path]/$isoname -r -C $session -M 0,1,0 -graft-points
backup/$backame=/tmp/backup
mkisofs -v -o [path]/$isoname -r -C $session -M 0,1,0 -graft-points
backup/$backname/*=/tmp/backup/*
with the same result, and
mkisofs -v -o [path]$isoname -r -C $session -M 0,1,0 /tmp/backup
fails to dump the contents of /tmp/backup into the root directory of the
CD. This failure occurs both when the original iso consists of an empty
directory, and /tmp/backup contains a directory holding a data file, and
when the original iso has multiple subdirectories, and when /tmp/backup
has in it only a single file.
Now, suppose, I try making the initial iso that of /tmp/backup. Then
the most recent mkisofs command (the one without the -graft-points),
with cdrecord, writes the contents of /tmp/backup to the disk. If I
want to take advantage of the multisession feature, and make another iso
of the (changed) /tmp/backup and write it to the CDR, I can still only
see the initial contents of /tmp/backup.
I have read README.multi and the man pages for mkisofs and cdrecord, yet
I clearly do not understand the syntax for mksisofs (particularly with
respect to -graft-points and multisession writing). Any light shed would
be greatly appreciated! In particular, for a multisession CD that will
be reading from a particular directory that will be changing every day,
1) what kind of iso should I initially make?
2) how can I get mkisofs to write the changed contents of the directory
to the CD (multisession)?
3) what is the syntax of -graft-points with regard to creation of
directories? what is its syntax with regard to grafting directories
onto the the initial iso?
BTW, I am using mkisofs 1.13 and cdrecord 1.9.
tia,
Cindy Huyser

This is a weird one, but whenever I write a disk with my IDE CDRW, any
downloads via my dial-up modem stop immediately. If I stop writing the
CDR, then the download resumes. I have tried this on two different
computers, and two different distributions, Mandrake 7.2 and Mandrake
8.0b2. I have tried my own kernel builds also. CD writer is set as
secondary master. This only seems to occur when using the ide-scsi
emulation for atapi CDR's. If I don't load ide-scsi, I can run
"cat /dev/hdc > /dev/null" or another such heavy I/O operation without
this problem.

kcore is a pseudofile representing the system memory. Only files
with the explicit name 'core' may be core files. If you have any
doubts use
file filename
If the file with name 'filename' is a core dump, the command will
tell you that.
There are a few files or directories on the system with the name 'core'
which are not core dumps. Do
locate core
to find them. But don't remove any files which are parts of the
system without being sure they are core dumps.

Hi
I can think of 3 reasons:
1. You arent doing something right, although it sounds like your pretty IT
literate, so that probally isnt the case.
2. The hdd may have gone bad.
3. You may have 'virus protection' turned on in the BIOS. If so, turn it
off, as it stops any programs from modifying the boot sector. If a setup
program cant write to the boot sector, the os will get installed, but the
boot loader (eg, lilo) wont. Also, just double check to make sure that you
hdd is in the boot sequence - sometimes it's the silly things that get
ovelooked that are the problem! :o)
I hope this helps,

I'm debugging/re-writing a very large shell script ( /bin/sh ).
Does anyone know if "sh" has a "goto" statement? It would be
quite helpful to "goto" a section of script ( bypassing code
that was already tested ) and pick up execution from there.

Why should you need goto?
There are other solutions available, post some real data, may be
someone knows what to do and is willing to share his knowledge
with you.
However, there is a ng comp.unix.shell, which may be better suited
