Strange init 3 behavior,
by akonstam＠trinity.edu
Has any one seen this behavior on FC4 systems, and know what to do about
it?
You go into a text terminal and wan to change to
init level 3, so you execute the command init 3. The machine hangs. (more about
this later)
So just to try something you enter init 1 instead of init 3. The machine
goes to init level 1. Aha you say. I know what to do and you type init 3
The machine not to be bested by a mere user changes to init
level 5.
A kind of work around>
If you go into a terminal and you type init 3 and it
hangs in various places depending on how long you wait and whether you hit
return. Now you hit ctrl-alt-f7 the screen goes black. You then hit
ctl-alt-f1 and eureka you are in init level 3. Is that obscure enough a
procedure for you. I tried this on three machines and it worked
every time.
What is happening here? Does any one know?

init 3 problem revisited.
by akonstam＠trinity.edu
People's answers to me have set me on the right track and here is what
I have observed now. I just can't understand that no one else has
noticed this glitch.
I made the shifting to init 3 in a terminal more mysterious than it
really is. crl-alt-f1 takes you into a terminal. Login as root and
run init 3. The machine seems to be hung but typing ctl-alt-f2 takes
you into another terminal window where of course you are not logged
on. Then typing ctrl-alt-f1 again will take you back to the first
terminal where you are logged on and in into level 3.
So as people have suggested the going into init level 3 is occurring
but what is not occurring is the last step in a problem we used to
have on previous fedoras where going into init 3 would stop at the
anacron stop step. To get a prompt you would have to hit return.
Now the return is not accepted and the machine seems to be hung.
Maybe a bugzilla is needed.

The problem with any unwritten law is that you don't know where to go

Rebuilding FC3 base kernel from source
by Philip Prindeville
What do I need to do to install the FC3 kernel sources and
build exactly the same kernel that comes with this distribution?
Somehow my install got hosed, and when my system boots I
get a lot of messages that insmod can load /lib/dm*.ko (at least
that's what I think it was).
Sigh.
Thanks,

Share internet connection/make a small server
by Antonio Olivares
Dear folks,
Recently at work, the network administrators
changed from static ip's to dhcp. They made changes
to use static dhcp using the mac address of the
machines connected to the network. Before I could
connect to the network using something like
[root@rio ~]# ifconfig eth0 10.154.20.157 netmask
255.255.248.0
[root@rio ~]# route add default gateway 10.154.16.1
[root@rio ~]# echo nameserver 10.128.0.4 >>
/etc/resolv.conf
Here's the info of that machine's connection after
system administrator connected the machine using mac
address.
[root@rio ~]# ifconfig -a
eth0 Link encap:Ethernet HWaddr
00:50:2C:A6:19:28

[root@rio ~]#
Now I cannot get network access. Even with dhcp
enabled. The network identifies the mac address of
the machine and assigns the same ip throughout.
I want to add an extra NIC/LAN card to this machine
call it eth1 and use the machine as a host for a small
network so that I can use/share the internet access
with other machines. I ask for advice/help on this
issue. I have read the following
http://www.tldp.org/HOWTO/DHCP/index.html
and
http://www.linux-mag.com/2000-04/networknirvana_01.html
but I am not sure how to begin. I have not placed the
nic card yet on the machine but I will do so tomorrow.
The machine has Fedora Core 3 with an everything
install. What do I need to setup a mini dhcp server
from this machine?
Thanks in advance,
Antonio

Bad magic number during fsck
by Smugzilla
Something really strange happened to my FC3 server running ext3 a few
days ago. It logged a "journal commit I/O error" and things started
getting screwy. The system isn't frozen, but my man pages are gone and I
can't get "ls" to show me anything. I tried running fsck last night and
got the following response:
[root@bender ~]# fsck
fsck 1.36 (05-Feb-2005)
e2fsck 1.36 (05-Feb-2005)
/: recovering journal
fsck.ext3: Bad magic number in super-block while trying to re-open /
e2fsck: io manager magic bad!
Then this morning, while typing up this message I tried fsck again and
got:
[root@bender ~]# fsck
fsck 1.36 (05-Feb-2005)
fsck.ext3: Unable to resolve 'LABEL=/'
I'm in way over my head here. Is there any way for me to fix my file
system, either using fsck or with Knoppix, or should I just backup as
much data as I can and reinstall the OS? And just as important, does
anyone know how this might have happened in the first place?
By the way, "ls" doesn't work for root, but it does work for other
users.
Thanks,
Pete S.

Re: [TLUG]: FC4: Ways to use PalmPilot
by pking123＠sympatico.ca
I found I was able to use JPilot, and it appears to do what I want.
But I seem to have run into a "feature" in FC4 which resets the
permissions on /dev/ttyS0 to 660 from 666.
I have looked through the kernel docs, and I do not suspect the
kernel is doing this. Any suggestions as to what is responsible for
resetting these permissions, and how do I make these changes
permanent?

To add more detail:
- no extended partitions ... just two primary ones
- the exact error is *** STOP 0x0000007B
(0x81826B10,0xC000014F,0x00000000,0x00000000)
INACCESSIBLE_BOOT_DEVICE ... followed by some chkdsk /f verbage.
- I just reproduced it by simply adding a primary linux type
partition taking up the rest of the space on disk and got rid of it by
deleting that partition
-w2k is on the first (and only) primary partition that is 150GB big and
the drive is 250 GB total and is SATA. I don't know if it is supposed to
but w2k does not report any free disk space after its partition when you
go into the disk management dialog.
I went through all the steps again so that they are fresh in my mind
- after adding the second primary partition, I booted to the recovery
console and tried:
- CHKDSK
- gives the informative and useful "The volume appears to
contain one or more unrecoverable problems." when the second primary
partition is present
(recovery) - removing the second partition causes w2k to boot
normally
- FIXMBR
- complains that the computer has a non-standard or invalid
master boot record and warns of dire consequences
- ... going through with it anyways has no effect other writing
a new MBR to \Device\Harddisk0\Partition0
- which clobbers grub if was there and the blue screen persists
with the first hex number after the bracket changing to 0x81877CB0
(recovery) - but after the second partition is removed, w2k
boots normally.
- FIXBOOT
- warned that the bootsector was corrupt after thinking that
the file system on the startup partition is unknown.
- It then checked the file system type and detected that it was
an NTFS system and wrote a new bootsector.
- This had no effect other than hooping the system such that it
wouldn't even begin to start the ntloader (A disk read error occured ...
Press Ctrl+Alt+Del to restart)
- looking at the output of sfdisk -d /dev/sda ... it appears to
have seriously pooched the partition table also making 4 overlapping
primary partitions
(recovery) - restoring the mbr (containing the 2 partitions)
from the backup image didn't make it work again but I got the blue
screen again (with a different hex number again like after the FIXMBR step)
(recovery) - removing the second primary partition caused w2k
to boot normally
So somehow w2k is getting seriously confused on my system ... turning on
/bootlog and /sos in w2k boot.ini and removing /fastdetect was not
illuminating.
I took dd snapshots at each step with Knoppix. Does anyone know of a
good hexeditor that I could view them in or ideally compare two binary
files?
My next step is to experiment with hidden partition types. If that works
I will file an RFE against anaconda to write more failsafe grub rules by
hiding the linux partitions.
Preliminary experiments would indicate that changing the partition to a
hidden type doesn't help. I am not sure if that is all the "hide"
command does in grub.

Thats an interesting way of doing it. I'll have to test that out too.
