Hi-
Probably an FAQ but it's not documented in man rsh
and I'm not sure where else to look.
Is a command such as "rsh localhost ls"
permitted as root?
Thanks,

I beleive that VMware is available for Linux an NT only, not Win98.
I would suggest runing Linux as the main OS and run Win98 under VMware.

Hello to everybody
does someone know why the startup of vim is so slow, especially for long
distance telnet ?
And possibly how to avoid this ?
I tried switches like -n (no swap file) but it didn,t help. I don't have
any rc-files.
Thanx,

The way I'd do this is to convert the file to Postscript using a2ps, then
use psselect to select the odd and even pages for printing. Better yet,
use the psmandup script, which handles odd/even page selection and printing
automatically.
a2ps and psmandup are in the a2ps package, and psselect is in psutils.
You probably want to convert the file to Postscript first anyway, since
this gives you a lot of control over fonts, formatting and layout.

I'd use vmware instead, because you can run several OS's at the same

Date: Mon, 22 May 2000 15:57:26 GMT
Hi,
This is almost 3 years old Slackware system, and today I noticed
for the first time a message which I never ever saw previously.
After usual "shutdown -r now" (I have to use MS Office to stay
compatible with the rest of my group) I noticed a new message,
which appears last after all the typical shutdown messages I used
to see for years:
...
On the next boot fsck will be FORCED
(and systems goes to reboot)
What makes me wonder is that in fact, _nothing_ is happening
on new reboots, I rebooted several times to see what will happen,
I'm just getting this message again and again.
I'm just wondering why is that ??
Thanks for any info and hints,
Rgds,
Andrei

This doesn't make a bit of sense from a user's perspective. You
are saying that I can use the code only as long as it isn't linked
to something else that I might happen to need that is under
someone else's control. I don't think the internet would exist
as we know it today had it not been for the reference BSD code
that does allow use in proprietary works as well as additional
free ones.

Subject: Debian 2.1 Linuxbox won't ping my other Linuxbox
Date: Mon, 22 May 2000 12:19:47 -0400
Hi,
I know that my hardware is ok because I had Redhat 5.1 on
the system and it was networked well with my other computer.
I just installed Debian 2.1 on the same computer by changing drives
so only one system is on and one drive in the system.
When I do ifconfig, I get both lo and eth0 listed with
my assigned ip of 10.0.0.2 for the computer. I can ping 10.0.0.2
but I can't ping my other computer. I can ping localhost also.
I don't now where the various config files are for the network
in Debian. The the file that I know of is /etc/networks. I don't
know what the minimum config that is needed to set up
a network card. If I do lsmod, it lists the ethernet modules
for my card. The only thing that I can think of at this point
is maybe the route has to be set up properly.
Anyone know if there is a network setup utility in Debian?
Thanks

Subject: hisax (isdn driver module) won't load...
Date: Mon, 22 May 2000 19:28:28 +0300
I have a Terton 128i passive isdn card. I'm told they are either WInbond
6692 or HFC PCI based, so I compiled hisax support for both in my
kernel, hisax as module. Then I installed isdn4k and isdn4linux and ran
"isdn setup".
Then, "modprobe hisax type=35 (or 36, tried both) io=0xd400 (this is
correct, I checked)" prints out:
/lib/modules/2.2.14-5.0/misc/hisax.o: init_module: Device or resource
busy
/lib/modules/2.2.14-5.0/misc/hisax.o: insmod
/lib/modules/2.2.14-5.0/misc/hisax.o failed
/lib/modules/2.2.14-5.0/misc/hisax.o: insmod hisax failed
and "insmod hisax type=36 (or 36) io=0xd400" prints:
/lib/modules/2.2.14-5.0/misc/hisax.o: init_module: Device or resource
busy
What could this mean? The sound card has the same irq as the isdn card,
but that works fine in windows and the sound card works in linux too.
What can be done?

I find it interesting that that number is mentioned so often. On 2.2.9
and 2.2.14, with ulimit-ing off, 1024 was the maximum open files. On
2.2.15, I also get 1024 from ulimit -a.

And, on 2.2.9 and 2.2.14, trying to increase the number dynamically didn't
work. Only by editing the source (as was recommended in previous versions)
would increase it....

Arun,
Goto /etc/X11 and edit your XF86config file so that it will look stg like
below:
Section "Device"

# Option "pci_burst_on"
# Option "xaa_benchmark" # DON'T use with "ext_eng_queue" !!!
# Option "ext_eng_queue" # Turbo-queue. This can cause drawing

The above setting starts the X server with 16 bit colors and 1024x768
resolution by default. My AOPEN PA55 card doesn't work properly without
"no_bitblt" and "sw_cursor". You may want to try without them.
Also set your monitor's refresh rates in section monitor like below:

Good luck,

I'd rename the directorys that you want to delete, leave them there but
renamed eg: "rm ./sparc sparc_tmp" for about a week or so and if you aren't
having any problems then delete them.
But having said this, if I'd upgraded my kernel I don't think I'd be in a
rush to delete any of the files that were used. You may need to recompile
the kerned again for some reason, and it may require the other directories
for some of it's information.

Note that at this time, the kernel developers are not answering bug
requests for earlier kernels, but instead are concentrating on
developing 2.3.x version kernels and maintaining 2.2.x version
kernels.

Go into a directory where you want to delete some stuff eg: home/jim/docs/tmp
do ls -l and you should get a list that hells you who owns what:
drwxr-xr-x 5 sjlen root 1024 May 20 22:49 sounds
-rw-r--r-- 1 sjlen root 5270 Apr 2 00:00 stsky.zip
drwxr-xr-x 3 sjlen root 2048 May 15 18:56 text
-rw-r--r-- 1 sjlen root 15723 May 19 00:50 title.jpg
The above listing tells me that the user sjlen owens both the
directories and both of the files listed.
You can change the owner of a file with the chown command do:
$ man chown
Then you can change the attributes of the file or files in
question with the chmod command see the chmod man page
for details, (briefly this command lets you change the read,
write, execute and other such attributes).

Only thing I can suggest is go through your setup routine for the NIC and
see if there's anything you've missed, and also go through the ADSL-HOWTO
and see if there's anything in there that helps.
If you havn't got the HOWTOs they're available from:

Well, you've heard from the Debian side, and they've given you a very
good argument for Debian, so as a long-time Slackware user I'll just add
in my two cents. :) Slackware does force you to learn to do
configuration by hand, though there ARE some utilities to help you in
that regard (pppsetup, whatever the network config is, etc). However,
this is better, IMHO, because that way you're not tempted to use the
nice graphical utilities as a crutch, and are a little less helpless
when those utilities fail you for some reason or another. :) I've TRIED
Debian, but I could never get into it. The two reasons are twofold:
one, Debian, like a lot of distros, goes for an
"everything-but-the-kitchen-sink" approach to what software they include
with the distro. Slackware is a lot slimmer, by comparison. Second,
neither Slackware's nor Debian's installation system is particularly
pretty, but Debian's had me tearing my hair out. I just found it
extremely arcane and unwieldly. That alone convinced me not to use
Debian anymore.
Anyway, that's just my $.02. My best recommendation, though, would be
to go to LinuxMall or Cheapbytes and buy $2 CD's of each, and try them
both out. Decide what YOU like best. :)

I assume you mean linux2 here.

In all the above, you may be getting confused; I see quite a few cases of
the same partition being assigned two different mount points, as in
/dev/hdc3 being both /usr and /home in the linux2 case. If these are
simple typos, then fine. If you thought these were correct as-is, then you
don't understand partitioning, Linux device files, and/or the mounting of
partitions. In brief, each device file (/dev/hda2, /dev/hdc3, or what have
you) is a unique partition that can be mounted on ONE mount point (/home,
/usr, or what have you) at a time. The same partition can be given
different mount points on different Linux installations to the same
computer, and you can even un-mount it and re-mount it under a different
name on a single Linux installation if it's not a critical partition like
/usr, but you cannot have it simultaneously mounted under two mount points
(as in /usr and /home at the same time).

Because the "mount table," as you call it, is stored in a file in the
/etc directory (/etc/fstab, to be precise), the problem is a non-problem.
When you boot linux1, / (and hence /etc/fstab) is on /dev/hda2, whereas
when you boot linux2, / (and hence /etc/fstab) is on /dev/hdc2. The
/etc/fstab file is AUTOMATICALLY different for the two Linuxes.
You will need to configure LILO (or some other boot loader) to handle two
Linux installations, but that should be too tricky. Yours might look
something like this:
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
image = /boot/bzImage-1
label = linux1
root = /dev/hda2
read-only
image=/linux2/boot/bzImage-2
label=linux2
root=/dev/hdc2
read-only
You'd install this lilo.conf file from linux1, with the linux2 root
partition (/dev/hdc2) mounted under /linux2. There are many variants on
this that would get the job done, too.
FWIW, I cover many of these issues in my book, _The Multi-Boot
Configuration Handbook_ (http://www.rodsbooks.com/multiboot/). Several
HOWTOs contain relevant information, too, particularly on basic
information like partitioning and use of LILO. Check
http://www.linuxdoc.org for these, or look on your Linux CD.

Hi all,
How do you format a floppy in linux?
I would like to format it with a linux filesystem so that I can mount it
and save some linux files on it. Thanks.
George
