Denial of service
by Karl Larsen
I thought the German Nazi was trying to get into my computer again.
So I turned off sshd but that didn't stop the problem. I am getting hit
several times a second by someone. I would sure like to at least know
the IP they are from.

Re: Rescuing files from an LVM partition

I agree. I got into LVM through fc4 defaults. It has
really not been a problem, but I have worried about it
because I have found the documentation terse to the
point of being opaque. However, I recently added a
bigger disk and thought to add some more space to my
LVM / partition, which is supposed to be the advantage
of LVM. It was really painful I ran "man lvm" and it
just dumped a bunch of tools infront of me with no
guide to how to use them. I did get it figured out
finally.
Now I am getting ready to "yum upgrade" and it seems
like LVM may help there. After that, I want to get rid
of LVM. Is there a guide somewhere on how to do that?
One of my worries is; if I copy my setup ( /) onto a
new ext3 partition, will the new one then be an LVM
setup? Will it copy all the confog files (wherever
they are?) or do I have to delete some? If I leave
/dev behind, is that enough to get rid of LVM?
That probably gives you a clew as to my level of
understanding of LVM. I don't think I am a dunce and I
have spent many hours trying to upgrade my grasp of
this system with no luck so I want to get it gone.

Try it again, but let it sit for a while. I saw the same thing on one
attempt at an install of 8rc2. I rebooted and tried again. I got
distracted at that point by a phone call, and as I talked, I saw it
suddenly continue.
There is a LONG delay which is probably some some 'wait-for-it' timeout.
Undoubtedly a structural error as it does not happen with F7.
On the subject of 8rc2, unless I did something wrong on a requested
reboot after the main install (leave the DVD in, or take it out? I took
it out) the installer does NOT ask you to create a user....I ended up
with a graphical boot, which does NOT allow a root user, but NO normal
user. (Had to switch to a console and mess around a lot with adduser and
passwd....).

'audit2why' was what I was thinking of.
'getsebool' shows only 2 Exim booleans, both off by default. Turning
these to 'on' made no difference. Running audit2allow, and following the
man page, changed things but the mail still fails. I now get (for
example):
==================================================
2007-10-04 12:40:07 H=tracy.csd.plymouth.ac.uk [141.163.177.2]
F=<condor-users-bounces(a)cs.wisc.edu> temporarily rejected RCPT
<john(a)jhorne.csd.plymouth.ac.uk>: require_files: error
for /home/john/Maildir/: Permission denied
==================================================
Now this isn't an selinux error, but, as said before, this was all
working fine. The directory Maildir certainly hasn't changed. I think
I'm basically going to have to disable selinux (because the mail works
then) and send the problem up to bugzilla so that it can be fixed in the
next update.
Thanks for your help,
John.

Sudden exim selinux problem
by John Horne
Hello,
I'm running F7 on my work PC, and use the Exim MTA to receive mail on
the PC from our central mailhubs. This has not been a problem since I
first installed F7, and I have been running it with selinux enabled.
However, for the past couple of days Exim has been rejecting
(temporarily) the mail due to what seems to be an selinux problem.
The exim mail log shows:
2007-10-04 11:07:06 cannot accept message: failed to stat spool
directory /var/spool/exim: Permission denied
The directory /var/spool/exim has not changed at all. However, if I
disable selinux using 'setenforce 0', then the mail comes though okay.
When the mail fails, the audit.log shows:
=========================================================
type=AVC msg=audit(1191493092.844:2346): avc: denied { getattr } for
pid=19983 comm="exim" name="/" dev=sda2 ino=2
scontext=user_u:system_r:exim_t:s0 tcontext=system_u:object_r:fs_t:s0
tclass=filesystem
type=SYSCALL msg=audit(1191493092.844:2346): arch=c000003e syscall=137
success=no exit=-13 a0=555555612ef0 a1=7fff8f28bf70 a2=0 a3=0 items=0
ppid=25399 pid=19983 auid=500 uid=93 gid=93 euid=93 suid=93 fsuid=93
egid=93 sgid=93 fsgid=93 tty=(none) comm="exim" exe="/usr/sbin/exim"
subj=user_u:system_r:exim_t:s0 key=(null)
=========================================================
I have yum automatic updates enabled, and can see that
selinux-policy-targeted has changed (updated to
selinux-policy-targeted-2.6.4-45.fc7), but cannot see any reference to
any Exim changes in the changelog. Exim itself has not been updated.
Anyone else noticed this, or any ideas about it? I'm currently looking
for that F7 utility that explains the audit.log entries a bit better and
how to (possibly) correct the problem. Trouble is I can't remember what
it is called! :-)
Thanks,
John.

I installed various updated alsa packeges (1.0.15-rc2) from development
I still have no sound
Any help???

If I remember correctly, I think I've gotten failed installs of grub by adding ,0 at setup
- not positive though. ----gary
