Hi, I'm a student attempting to use JSP in Linux but i notice few
questions in linux newsgroup on JSP. I would appreciate it if anyone had
used JSP in Linux and could share their experiences with me, good and
bad.
Also in particular, which free JSP implementations should i use
1) GNU ServerPages by bitmechanic, or
2) GNU JavaServer Pages by klomp
Thank you very much.

You are describing NIS (also called YP.) It's been a standard in *NIX forever.
Home directories automounted when someone logs in via automount, NIS
passwords and NIS automounts.

Hi, I am using redhat 6.2 on kernel 2.2.12, on an hp ppro 200 system
with so and so mb memory.
Problem: I installed in.pop3d version 1.005l for my server and didn't
have any problems for 3 months. All of a sudden I am getting this error
message: "-ERR being read already /var/spool/mail/user"
I had this problem once before, but only with a single user. I simply
had to remove the lock file for that account from /var/tmp.
This current problem is affecting all of my users simultaneously and has
brought down my entire system.
Furthermore I tried to install GNU-POP3d but also had problems. I know
that sendmail is working, because I can access my mail through pine.
Gnu-pop3d gave me a similiar error: "-ERR bad login"
If anyone has had similiar problems, or if anyone has any suggestions as
to what I could do, I would be most appreciative.
Thanks in advance.

In principle, the installation should have created a boot
floppy for you. (If it didn't, reinstall but use the
upgraded Anaconda installation floppy images from the RedHat
Errata or a mirror site. Actually, you could probably just
choose the upgrade option if you have already installed.)
Boot from that and use fdisk to
show your partitioning. For IDE disks,
fdisk -l /dev/hda
fdisk -l /dev/hdb
will exhibit the partitioning information. That way we can
tell if you have encountered the 1024 cylinder limit.
For completeness, also show us what
more /etc/lilo.conf
shows, but I expect that would not be the problem.
If you aren't encountering the 1024 cylinder limit problem,
there could be some geometry mismatch. You would have to give
us more detail about your BIOS and whatever else you can tell
us. And of course, there could just have been some glitch
in the installation such that lilo was not run properly and
doing again will resolve the issue.
If you are encountering the 1024 cylinder limit problem,
although there is a new version of lilo which overcomes the
problem, you probably can't use it because your BIOS probably
doesn't support the extended BIOS call that is necessary.
You can try adding the linear option and see what happens,
but either you will have to repartition with /boot in
a partition below cylinder 1024, use loadlin or something
similar, or just boot from a floppy.

if you check lilo.conf, it specifies where the root partition is and
all the other partitions are mounted onto that. Ihis root partition
can be hardcoded into the kernel using rdev but normally lilo memorizes
it.
Everything you run lilo, it figures out the location on the drive of the
kernel and remembers its cylinder, and sector.

I had the same problem and could not get 3.1 to work for love, money, or
threats. So I had to "back level" to 3.0.4. Luckily, I figured out a way
to do this since rpm itself couldn't. Find the rpm file for your old release.
Copy it to say, /tmp/rpm. Now do "rpm2cpio rpm-3.0.4.rpm >x.cpio". You must
change the first to the name of the rpm file. The second doesn't matter, it
just going to be a work file. Now extract from the "x.cpio" file that you
created. The command I used was:
cpio -i --make-directories --no-absolute-filenames <x.cpio
You will now have a file /tmp/rpm/bin/rpm . this is the version of rpm that
was in the rpm-3.0.4.rpm file. You can now run this and do a --oldpackage
and --force to reinstall the old version of rpm.
/tmp/rpm/bin/rpm --Uvh --force --oldpackage /tmp/rpm/rpm-3.0.4.rpm
Please change the file names to be what you need them to be. Oh, and once
the 3.0 version of rpm is installed, feel free to "rm -r /tmp/rpm". Or
maybe save it "just in case".
Hope this helps,
John

The users are only going to use LINUX terminals connected to a LINUX server
the problem is having them log onto a remote machine where work is going to
be stored and where their logon passwords can be authenticated instead of
duplicating every users account on every machine.
ps. Secondary problem is that the different users may need to log onto

Ok, so many partitions allow the OS to be broken up into seperate pieces. Your
mentioned a malicious user filling up space so I guess one advantage to
partitioning the OS into smaller pieces is to better manage memory? So
partitioning the OS into seperate pieces is basically for security?

You are just about on to what I am trying to do. Using a third HD to backup
both my Windows HD and my Linux HD. When I backup Linux, the backup HD is hdb.
Yes, that is precisely what I am trying to acheive. If lightening should strike
and I somehow lose data on my primary Linux drive I want to be able to boot the
backup and use it as my primary until I arrange another backup situation. Do
you see what I am saying? Now my problem has been the inability to boot the
backup with everything working. Its like I am trying to cloned the primary.
With Windows I simply use a tool that copies one partition to another. Since
Windows is all on one partition, presto! your done and you can run the backup as
your primary if you wanted. But with Linux I don't know that there are any
tools to do that so it is being MUCH, MUCH more difficult (its rather
discouraging that I have to go through so much hell to do this).
I have to mount the two backup partitions onto the primary drive. I am using
"mount /dev/hdb5 /backup" and "mount /dev/hdb6 /backup/usr". I copy directories
that I want on the backup hdb5 to /backup. Then the rest of the directories I
copy over to /backup/usr which is hdb6. Since the primary is all on one
partition (not including Swap) I have to correct the fstab file on the backup to
reflect its two partitions (not including Swap). Now with LILO installed on the
backup I boot it. What happens on the backup is the Xwindows system is screwed
up, the file system is read only and either both partitions are not mounted
(even though fstab says they should be) and/or the /usr directory on what is now
hda6 looks like /usr/usr/local/..., /usr/var/..., /usr/usr/home/..., etc. Not a
pretty site. All this seems like it should be so easy but Linux is not allowing
it to be.
Can anyone see what I am trying to do and what could be going wrong here? This
to me is should be the best way to backup my software on just a standalone PC.
Linux is simply not allowing me to copy all files from one drive to another
seamlessly.

Winlinux's file names are not %100 compatible
with fat from my experience, so you will probably
have to reinstall. I have had scandisk "correct"
\linux entrys, and it is then unusable. I
believe almost any fat-fat32 conversion will do a
check of all file names before conversion to
prevent converting a corrupted disk. Also
winlinux takes much less space under fat32 due to
the high number of tiny files.

No. For maintainability and managability (which you may call security).
You might, for example, probably expect to have one /boot partition shared
between all your o/s's, and also one /usr/X11R6 partition shared between
all your distros (if the distros have done it right) since XF86 isn't
controlled by anyone except xfree86 so the layout shouldn't be meddled
with (RH, you hear?).
You might also expect to have a small / partition (say 32-64M) to
minimize the chanze of a stray disk head wiping your root and also
to allow you to copy and restore it quickly (I mirror it to the
other end of the disk). And you'd expect to have a separate /usr/local
partition so you could share your additions between distros, and
also keep them safe from distro upgrades.

Via Tar.gz:

That should be all you'll need to do. If you have any other questions,

OK, Peter, thanks. That's what I'll do. I am sensing that understanding partitioning
and how the file system interacts with it is key to becoming good at using Linux.
Right now, obviously, I am a little green with that understanding.
If you are so inclined can you tell me if you backup your Linux files and if so how do

As root run crontab -e and comment out whatever these jobs are. I have
SuSE 6.2 and I can't recall what some of the cron jobs do (and they may
have added others since 6.2). I think one of them rebuilds the locate

I think you also mentioned that rm itself doesn't work so I would

This is a dump of the process image at the time of failure. It is used by

is/should be an option to disable "core" images from being created. There

There's AFS but only the client part has been ported. It's much better

Herein lies one of my biggest complaints about the Linux development

rely on undocumented "catch-all" calls to accomplish simple tasks. The
"man ioctl_list" page is a complete waste of time-- it's hopelessly out of
date and only contains the argument type for each command without any
explaination of where, why or how each should be used. Application
programmers shouldn't have to resort to sifting through the kernel source
code to figure out how to perform simple and common tasks.
People who write device drivers or kernel modules should provide a proper
man(2) or man(3) page. Ideally, we should kill off the ioctl() function
and place all accessible driver variables in /proc.

To be pedantic, I believe the C standard reserves all names that begin
with an underscore so you shouldn't use one in your variable or tag
names.

You can mount SMB share in Linux as well. Although, those don't
seem to be any better than NFS. (Yes, I've tried both head to head)
