Wondering if anyone out there has "successfully" configured the HP 693c
Color InkJet
printer under Linux. If so, how.
I have it working, sporadically. It will print some pages and then all
of a sudden just start spitting out
garabage. Any ideas?
I am running Redhat 6.2 and have it setup under printtool as an HP
Deskjet 550C (UP) on /dev/lp0
- Thanks

A little advice:
1. Make a detailed list of all hardware you have, including
settings. Also include BIOS settings.
2. Read a little about stuff you don't understand, then proceed.
3. Have a pencil and paper handy to record what happens, plus all
the information that springs forth during the install that will
be useful later.
OR
Just stick the CD in and go for it. In case of troubles, goto
step #1 above.

FDISK.EXE and fdisk write to the partition table, not any superblocks
that might be present. What you're looking for is "mke2fs", I think.
Linux doesn't use the partition type info in the partition table for
much of anything, preferring to read the superblock directly and deal
with the filesystem from there.

Now, if I understand correctly, you have two simultaneous distributions
on this machine, and you can't boot into either one. Is that correct?
If so, how far do you get into booting either of them, I know you say
you see a message "stage1", but is there any more, at all? IIRC, Mandrake
and slackware use two different boot loaders. Which one are you using?
It sounds from the "stage1" thing like you are having a problem with "grub".
Maybe booting from installation media, and poking around (or perhaps even
reinstalling grub) will help.

If you are installing Mandrake 7.1 just read the docs it has with it. I
have installed Mandrake 7.1 on many boxes and never had a problem on
anything more modern then a P90. It does a very good job at detection. If
you put the kernel where lilo can't reach grub is used automatically. The
mandrake 7.1 install is about the easiest linux install I have ever used.
That is why whenever I help a customer who wants to get rid of windows I
help them dual boot Mandrake and let them install it with me watching.
Usually they never ask me a single question during the install. Usually I
get comments about how easy it is to set up.

swprintf() should be in the C library, but it doesn't exist yet.
Some time ago, Ulrich Drepper asked about multibyte printf on
comp.lang.c.moderated (see <news:[EMAIL PROTECTED]>)
so I guess he'll be adding it in the next version.

You can print the output of this to a file so that you can have a record
to look at. Something like this.
/bin/grep "Packet log" /var/log/messages >
/home/user/filename/to/rocord/to
Or use the following to view the output to an xterm.
/bin/grep "Packet log" /var/log/messages | more

Hi,
My Gnapster 1.3.5 has been disfunctional for about a month. I know that
Windows Napster users are having no problems. My Gnapster keeps "Finding
best host" forever. It used to function perfectly before. Probably,
there was some change in Napster servers, so the native Napster could
handle it, while Gnapster couldn't.
I'd like to know what other Linux users are using instead of Gnapster
now.
Thanks in advance.

You will need to add the line below to /etc/fstab
This will allow all users to access the windoz partition from within
linux. They will also be able to delete files and/or destroy windoz if
they choose to.
YOU HAVE BEEN WARNED!!
These 2 lines should all be on one line in /etc/fstab be sure to use the
correct partition for /dev/hdaX
/dev/hdaX /mnt/w98 vfat
user,owner,exec,dev,suid,rw,noauto 0 0
Then "mkdir /mnt/w98"
Then to access it you would:
mount /mnt/w98
Hope this helps.

I'm new to the linux environment. I'm running Red Hat 6.0 and I'm trying to
get it to recognize my network card. I found the module for my card and
used the command 'insmod /lib/modules/2.2.5-15/net/3c509.o'. I set up all
of my network settings and everything works fine. When I restart the
computer, I have to type the insmod command again to get it back going.
Once that command is issued, shouldn't it stay in the kernel even after I
reboot? I basically want to set up my system so that I don't have to add
the module every time. Does anybody have any suggestions? Any help is

I'm not sure if it'll work (nor if it is a wise thing to do) but you

Does your mail logs and/or syslog say anything about denying SMTP
access from a host or something like that?
Did you just upgrade your MTA? Has it ever worked?

First create a mount point, an empty directory through while you can
access the windows partition under Linux. Doing something like
'mkdir /mnt/winc' will do. Now mount the windows partition like
'mount /dev/hda1 /mnt/winc' and you can access it at /mnt/winc.
Accessing a Linux partition under Windows is more difficult because
there is naturally no driver that comes as part of Windows. However
there are some free ext2 drivers for Windows available on the net
though I have not personally tried them.

Subject: Re: Kernel Panic: VFS: unsupported optional features
Date: Wed, 20 Sep 2000 03:33:49 -0400
I had the same error recently. I had an emergency and needed to boot with an
older
kernel (2.0.36) which couldn't read some of my ext2 filesystems ( / and /usr
unfortunately). When I managed to get a working 2.2.14 kernel back on the
system,
everything was fine again. If your disks were created on a different machine,
perhaps
a newer version of fstools was used than what you have installed? I haven't been
able
to find documentation of the reason for the error, but the difference in my case
was
only the relative age of the kernels and when the filesystems were created.
Hope this helps,
Bob

Under X or console?
Under X, you have already got some answers. Under console, figure out
which console you use, say /dev/tty3, and do (possibly from another
console) a
cat /dev/vcsX
where X is the console number. (3 in the previous example.)

The utmp file is a binary file. You *should* be seeing stars, yen
signs and at signs and stuff on your screen (and the speaker probably
beeps a bit too) if you view it with e.g. 'cat'.
If it (your problem) is indeed due to a corrupted utmp file, then one
may ask oneself why it is corrupted. Some bad crackers tries to change
the utmp file so that their cracker run isn't documented in it. If
they screw up, then they corrupt the file. BUT:
Note that the utmp struct from libc5 has changed in libc6.
Because of this, binaries using the old libc5 struct will
corrupt /var/run/utmp and/or /var/log/wtmp. Debian
systems include a patched libc5 which uses the new utmp
format. The problem still exists with wtmp since it's
accessed directly in libc5.
You may remove the utmp file and create a new empty file by 'touch'ing
it. My utmp file (on Debian 2.2 mind you) has the following
permissions set:
[hurd] ~ $ ls -l /var/run/utmp
-rw-rw-r-- 1 root utmp 8.6k sep 19 19:11 /var/run/utmp
Another way would be to "cat /dev/null > /var/run/utmp".
Before trusting me on this, search the LDP at
<URL:http://www.linuxdoc.org/> for info about the utmp file and what
you may and may not do with it.

If you have a fast link.
