Yeah, and the technical expertise to recover the partition table, You all still
haven't explained why Disk Druid even accessed that drive, it was being used on a

Subject: Lockup solved! It was RAM not properly seated...
Date: Thu, 03 Jun 1999 11:32:15 -0400
Hello,
First of all, thanks for all your comments.
It was two sticks of RAM not properly seated or not-so-perfect
contact of RAM sticks in the memory banks.
Here's the scoop:
1. Originally, the machine was running fine with 2 sticks of 128MB
PC100 RAM (chip from Micron, PCB from nowhere).
2. The motherboard (Gigabyte 6BXD) has 4 memory banks. I added
two more sticks of 128MB PC100 RAM (chip from Fujitsu, PCB from
nowhere).
3. Soon, I added 2nd NIC (Linksys 10/100TX)
4. Now I see random lockups from netscape (once in a week or so)
and more seriously my fortran code, which normaly takes full 7
days to finish, catches signal 11 about once in 2 days. The
program dies with coredump and I'm devastated. I know bad codes
can generate segmentation fault, but I'm sure it's not the code's
fault.
5. I switched the slot locations of RAMs.
Fujitsu -> Bank 0,1
Micron -> Bank 2,3
While at it, I pressed the RAM sticks hard enough into the slots
almost breaking the motherboard PCB :^)
6. For a quick test, I compiled kernel-2.2.9 about 20 times.
Compiles fine every time.
My fortran code is running (two copies, making full use of SMP)
for 4 days without a hiccup.
7. Once again, I become a happy man.
Hope this helps anyone in a similar situation.

Side comment: have you actually looked at the kernel filesystem code? :-)
It's doing *exactly* this -- although it's implemented in C, not
C++, so the virtual tables have to be explicit.
But here's a representative sample, from ext2:
static struct file_operations ext2_file_operations = {
ext2_file_lseek, /* lseek */
generic_file_read, /* read */
ext2_file_write, /* write */
NULL, /* readdir - bad */
NULL, /* poll - default */
ext2_ioctl, /* ioctl */
generic_file_mmap, /* mmap */
#if BITS_PER_LONG == 64
NULL, /* no special open is needed */
#else
ext2_open_file,
#endif
NULL, /* flush */
ext2_release_file, /* release */
ext2_sync_file, /* fsync */
NULL, /* fasync */
NULL, /* check_media_change */
NULL /* revalidate */
};
struct inode_operations ext2_file_inode_operations = {
&ext2_file_operations,/* default file operations */
NULL, /* create */
NULL, /* lookup */
NULL, /* link */
NULL, /* unlink */
NULL, /* symlink */
NULL, /* mkdir */
NULL, /* rmdir */
NULL, /* mknod */
NULL, /* rename */
NULL, /* readlink */
NULL, /* follow_link */
generic_readpage, /* readpage */
NULL, /* writepage */
ext2_bmap, /* bmap */
ext2_truncate, /* truncate */
ext2_permission, /* permission */
NULL /* smap */
};
(and there's ext2_dir_operations, ext2_dir_inode_operations,
and ext2_symlink_inode_operations. I won't bore you with
the details, but all of this is in /usr/src/linux/fs/ext2
in various *.c files.)
static struct super_operations ext2_sops = {
ext2_read_inode,
ext2_write_inode,
ext2_put_inode,
ext2_delete_inode,
NULL,
ext2_put_super,
ext2_write_super,
ext2_statfs,
ext2_remount
};
Neat, huh? :-)
I don't know offhand where all of these structures are referenced
and called, but it's obvious we've got a little OO going on internally.

On the other hand, Sybase is a proven enterprise-class database

If you're serious about using a database in a critical environment
(say, where money's being tracked) you'll be glad that MySQL comes
with source because you'll be rewriting it to be transaction-based...

$20 solaris is for personal use only. Solaris' system requirements is quite high

Hi. I installed kde and I was trying to run kdm when.
I got an ancient slackware that I've been upgrading, it's got
kernel-2.2.9 and latests everythings.
My problem is that the kde login only lets me enter in the
failsafe mode. Every other seems to start but comes back
to the login screen.
When I run in failsafe I got to do
. /etc/profile
startkde
I've been reading docs and wandering deja news
unsuccessfull. What am I missing ?
I just installed kde-1.1.1 and keeps doing the
same.

I need to restore two tapes of data (QIC-80 tape backup) into a Xenix 386
(2.3.4) system.
Because I was not able to install the tape driver in Xenix I installed it
in Linux, and copied the tapes to
to the Linux harddrive (ext2 fs).
Then, I tried to mount the xenix harddrive as a second harddisk in Linux,
but the mount command
does�nt recoginize the filesystem.
I compiled the kernel to support xenix, sysv and coeherent filesystem. But
still doesn�t work
If I do �fdisk /dev/hdd� the xenix partition is shown but mount does not
work.
What can I do?
Thanks in advance.

in my opinion the best way to get icq working without an icq daemon is to
run a firewall which also works great with masquerading. the best way is to
install masquerading which is quite easy to do and then run my firewall
script which can be obtained at http://rage.chroot.net/firewall. just
download it and chmod it 755. that way you can excute it. it supports both
eth0 and ppp0 so basically it takes any packets which doesn't resolve and
foward them to ppp0 (the internet). works quite well with icq. you can also
download an icq module (check linuxapps.com). good luck and feel free to
mail me for addition help.

It can hurt, most IDE drives are not designed to be low-level formatted.
Low-level formatting was used with the old MFM/RLL drives, but is not intended
for modern IDE drives. Performing a low-level format on a drive that is not
designed to handle it can destroy the drive.

Don't use ICQ, it's got some incredible security holes. Use IRC, it's been
around for ages, works well, clients are available for many more platforms
than ICQ, and there are many servers to choose from. TTYL!

Or, in other words: It's much better to completely crash and burn than
to produce results that look valid, but aren't. One of the first lessons

Some fax software obeys the lock convention. Ie, try putting the
lock
option into for example /etc/ppp/options.
The fax getty may if it notices some stuff happening on the line, look
for the lock file before it tries to answer the line and grab the fax.
This is how mgetty for example works.d
Arfe you really receiving faxes on your modem. If you are just sending
them, then the faxgetty should not need to run.
But it all depends on exactly which fax software you are running.

Not quite that bad, Oracle wants about $6K, and if you can
convince them that your web site's low traffic and will only
have five connections at a time you should be able to get
away with the $1400-ish 5 user base license (their cheapest).
All these commercial engines are total overkill for most of
us doing database-backed sites, though and come with
significant administrative overhead.
Postgres is easy to use, still too flakey, but getting better
and is transaction based. As it continues to mature, it
should be a good choice for the kind of smaller db-backed
web sites you'll likely run on an x86/Linux box.
Meanwhile, MySQL seems like a good choice if you don't
need the transaction model.

Windows 9x is so selfish it takes the first partition on the C drive and the
whole Master Boot Record to itself!
Might be easiest if you bought another hard disk, made it master (ie c: ),
and jumpered the Linux disk to be slave.
Make a boot disk for Linux and test it works.
Install windows.
Boot linux with the boot disk.
Configure and run Lilo, and you should be right -- ie back to dual-boot
system
