Very Computer

I am currently running a stable Linux system with a kernel version
1.2.13. Because I am about to add new hardware to my system (ISDN
adaptor board, CD-changer) I think a kernel upgrade is in order.

Can I just ftp and compile the 2.0.20 kernel source and leave the rest
of my Linux system unchanged? Or do I need to upgrade other parts of the
system as well? (C-libs?) If I just upgrade the kernel and nothing else,
will I still have a stable system that allows me to compile software
distributions without problems?

I could, of course, just install a brandnew Slacware distribution, but I
have spent considerable time installing and tuning things like PPP, X,
DOSemu and so on, and I don't really look forward to doing that all over
again.

Any advice appreciated. If you reply, please include an Email copy (to

regularly.

Thanks!

The file Documentation/Changes in the kernel source has detailed
upgrade instructions. Yes, you need to upgrade other parts of your
systems as well.

BTW, does everyone know whether the Changes file is somewhere on the
web? How about the rest of the kernel source?

Hi, I just upgraded from 1.2.8 to 2.0.12 (by reformatting my hard drive
and installing slackware 3.1.0) and now I can't seem to print anything
on my HP 5MP printer connected via a parallel port.  I send the file,
but printer doesn't even start flashing.  I read the Sept 10th version
of the Printing HOWTO, but that didn't help.  Someone please tell me
what's going on!  Thanks!!!

Some info:

------------------------
cat /proc/devices returns:

Character devices:
 1 mem
 2 pty
 3 ttyp
 4 ttyp
 5 cua
 6 lp    <---- I compiled in parallel port support into the kernel
 7 vcs
10 misc
14 sound
27 ft

Block devices:
 2 fd
 3 ide0
22 ide1

-----------------
My printcap file (I greatly simplified it and it still doesn't work):

test|test:\
        :sd=/var/spool/lpd/: \
        :mx#0: \
        :lp=/dev/lp0: \
        :sh:

-----------------

ps aux | grep lpd returns:

root      1088  1.0  1.0   788   312  ?  S    14:19   0:00 /usr/sbin/lpd
root      1090  0.0  1.0   796   320  ?  S    14:19   0:00 /usr/sbin/lpd
zzkaru    1095  0.0  0.9   864   300  p2 S    14:19   0:00 grep lpd

After a bit of screwing around, I finally fixed my printing problems.
Here is the printcap and associated filter that worked for me.

HP5MP printer hooked up via a parallel port:

lp|hpj:\
        :lp=/dev/lp1: \
        :sd=/var/spool/lp1: \
        :lf=/var/spool/lp1/errs: \
        :if=/var/spool/lp1/hp5mp_input_filter: \
        :mx#0: \
        :sh: \
        :sf:

contents of /var/spool/lp1/hp5mp_input_filter
BE SURE TO chmod a+x this file to make it executable!

#!/bin/sh
# above assumes bash shell
# 0 = numeral 0
# \\033 is the code for ESC in octal, followed by printer command code
# translate LF -> CR+LF:
echo -ne \\033\&k2G
#
# if you wan to wrap long lines:
echo -ne \\033\&s0C
#
# Send the file thru:
cat
#
# Add a final form-feed if you want:
echo -ne \\f

ftp shopping lists:

http://www.cviog.uga.edu/LinuxBleed.html
http://www.ecsnet.com/html/linux_other.html <- this site gives other
info too, like the step by step cheat sheet. That's where I started off.
the cviogog site is great too.

I had/have the following problems:

tzcode96l.tar.gz + tzdata96k.tar.gz needed downloading
several times to arrive without CRC errors.

procps-1.01.tgz needs X include- and other programs
to run make all completely.

can't make ld.so-1.8.0 due to missing define of LDSO_ADDR in some
program.
( will make separate post )

the ecsnet site lists RedHat .rpm files to be installed. I got
the rpm program but is needs some kind of database to do the
installation. I gave up for now. ( on rpm's )

Other from that - the kernel boots and runs fine - so far but I still
need to knit some things together ( ld.so ).  

Good Luck and enjoy!
