I am having some problems with my ppp setup, I am using zipslack. I have
entered all the information (found out from my ISP) but when I give the
ppp-go command it says 'Connect script failed'.
I would be very gratefull to anyone who can tell me what could cause this
error.
Thanks

I downloaded the two RH7.0 iso images off of a redhat mirror. I burned the
first one to CD using EasyCD creator 4.0... i was under the impression that
it was a bootable. That .iso file is the only thing on the cd, however no
system will boot off the CD. If I put my Win2K Pro CD in, those systems
boot fine off the CD.
What did I miss?

err, sorry, I just thought I might reduce the noise pollution. Thanks for
caring.
Mainly my discovories are [which might be hints for newbie helping docs]:
A boot disk has two types:
one that just contains the MBR
one that has more --- a rescue disk
one that has even more: a linux complete on a floppy... ok 3rd type.
also I never expected it to be true that one could just
edit menu.lst and not even run a command and it would affect things---true
in some cases. This is diffrerent than lilo it seems. one still needs to run
lilo.
All these newbie things aren't really mentioned often.
A question I have is "installing lilo/grub on windows hda or hda1"
there are apparantly seveal degrees to such an installation.
one would be just writing to the MBR of hda.
another degree would entail more space on hda or hda1, but is there
such space waiting or will a windows thingy get ruined in the process.
I'm thinking the best thing would be if the boot process would not invold both
hda hdb abd floppy. i.e., revove the windows disk and still can boot linux,
remove linux disk and still boot windows----all with the minimal amount of
reconfiguration.

though I had to take out the 81-80-80-81 crossmap stuff to get into windows...
this is a clue to me as I mentioned in a more recient missive. ok thanks.

indeed, i'm sure if I finally give in and overwrite MBR of hda, all will be
simple...
I just thought I could get away with overwriting MBR of hdb for the same
effect..

hello,
talk is a rpc service and therefor needs the rpc-portmapper running.
you dont really want this stuff on your box tho since the whole
rpc-crap is wellknown for a long, dark history of bugs, slips and
remotely exploitable security holes.
the portmapper also is required for the unfamous
ugly-but-still-hardly-avoidable nfs service.
so if you export nfs-shares you may as well run talkd, just be sure to
read up on and _understand_ the potential security problems nfs/rpc
usually introduce.
i would recommend to rather set up an ircd or instant messenger
service if you need external<->internal live communication, the
talk/rpc stuff is broken by design and should - imo - be avoided
whenever possible.
i will very soon release a console/ncurses-based multiuser splitscreen
chat utility (very similar to talk) on freshmeat. i wrote it up
because i wanted to offer the users on the boxes i admin a simple,
secure way to communicate w/ each other.
the daemon as well as the client both run w/o root-privilegs and
should be rather bulletproof against any kind of attack.
keep an eye on freshmeat.net for "partyline" or if you cant wait drop
me a line and i'll send you a beta-tarball.. :)
the whole thing is almost done, just still got to make it customizable
(config-file), write some documentation and finish off/tidy up the
code...
regards, m.k.

Well, remove the files you installed. Get the list from the tar.gz (I

Subject: I'm screwed!!! Gnome menu fonts GONE!
Date: Tue, 05 Dec 2000 18:08:37 -0700
hi all,
I desperately need some help. This morning when I booted X the gnome
main menu was very skinny and only showed the icons but no fonts! Same
thing with the menus when I right-click on the desktop, etc. Also, with
the Control Center I am missing many fonts in that dialog as well. I've
restarted, reinstalled helix-gnome, rebooted, etc. but to no avail.
But note that all of my fonts in Netscape (I'm writing this from the
same machine right now) and the gnome-terminal windows show up fine
(except for the menu at the top of the gnome-terminal window).
I am running the following:
RH 6.2
Helix Gnome (yes, I reinstalled the whole thing again today after I had
this problem, but it didn't help!)
256 MB memory
PIII 733
Has anyone seen or heard of this before? I have exhausted almost every
possible option, but nothing seems to help.
Thanks in advance.

Sorry, I do not know or use smb. But right now you want to get a decent boot up.
a) let it go for a half hour. See if what ever is hanging the boot times out.
b) remove smb and see if that fixes it. Right now you want to narrow down the
problem. You can later add in what you need.
c) Put both the nickname and the fully qualified names for the various hosts into
/etc/hosts.

I never noticed the Linux extended type when I set the hd up(probably
selective seeing).
If I change the System to Linux extended on hdb3, will I need to do
anything to hdb4? Hdb1 and hdb2 should be okay, right?
I will back it all up anyway and redo the drive in the next couple of
days.
Noble Pepper, I was having trouble seeing hda from hdb, therefore could
not put the kernel on hda3. Fixed that problem but used your advice
about the image parameter. I missed the perfect example on the MAN
page. (More of that selective seeing!)
Appreciate your help Noble Pepper and Eric.

You cannot. What you can do so can others. YOu can limit the logon to coming from
some specific host or group of hosts (ie if you only ever intend to log in from

Steve,
Thanks for your help.
I do not know why I said fdisk. I realize it is for partitioning the
hard drive not for formatting. I allowed the setup from the disk to
format the partition. There must be something wrong with it or the way
I used it. The reason I say this is because I ran mke2fs on the
/dev/hda3 partition and reloaded Slack7.1. Everything went fine. Ran
LILO from my original distro, rebooted and was able to get to /dev/hda3.
I also had the same problem after installing Slack7.1 on /hdb2. This
made me think about running mke2fs on both ( after reading your post of
course). By the by, the partitions were created at least a year ago in
preparation for checking out different distros of Linux.
Again, Thank you for your help.

I don't think there are only very few people doing it, as it's a good
thing (tm)!
As for the kernels: 2.2.17pre6 is the default kernel in Debian 2.2 r0
(as 2.2.16 is even more broken). [ Btw, in 2.2 r2, 2.2.18pre21 is the
default kernel for an analog reasons ;) ]
I needed 2.2.18(prewhatever) as I needed USB. That just to
explain. Basically, its not the kernel causing the "failure" here. I
actually tested it with 2.2.17 stable AND 2.4.0-test<something> as
well.

Actually, the problems were on two raid0s, one 12 G, the other about 5 G.

Still not finding any info about how to exactly specify the "chunk size"
in the kernel parms, I made a exhaustive test. The results for
my two raid0s are:
mdtab : /dev/md0 raid0,16k,0,802eab69 /dev/hda3 /dev/hdc2
kernel args: md=0,0,2,0,/dev/hda3,/dev/hdc2
^--"chunk size": 2 works
mdtab : /dev/md0 raid0,8k,0,08716985 /dev/sda3 /dev/sdb1 /dev/sdc1
kernel args: md=0,0,1,0,/dev/sda3,/dev/sdb1,/dev/sdc1
^--"chunk size": 1 works
Other values for the chunk size (factor) (tested 1-16) do NOT
work. Obviously, "mdtab-value == kargs-value x 8k" must be met. This
really should be in kernel's md.txt, imho.

My normal disk / fs layout is to only have a small /boot partition on
a bios-secure place and some swap space partition. All the rest is
root-raid. This obviously has two advantages:
1. Speed (striping).
2. No fixed space mounted partitions (which is REALLY annoying).
I don't have a clean "old-style" root partition any more to boot
from. I get security by other means. Previously, I had that, using the
raid via symlinks, but that solution has some disadvantages, besides
the fact that it is ugly !

Stephan
