It seems to me this would be much more useful info to a newbie
if you explained what and where "dag" is,
since it is not a standard part of the yum setup on Fedora-3.

Eg I have
=======================================
[tim@martha ~]$ cat /etc/yum.repos.d/dag.repo
[dag]
name=Dag RPM Repository for Fedora Core
baseurl=http://apt.sw.be/fedora/$releasever/en/$basearch/dag
gpgcheck=1
enabled=0

Aha! Yep, I forgot "this isn't windoze" .... you know that being a Win user
is like being an addict. You always want to go back to that needle.

Anyway, you advice sounds great. I read about the rpm and yum remove but
was nervous ... now I know why!

I'll start with a few of the more obvious culprits and get back to the
group.

Thanks!

In addition, the OP might like to check the postfix FAQ and if
this doesn't help try the postfix mailing list, more likely to
get specific help, then here.

Good luck

Fedora Core 3 Installation Hangs

Posted: 23 May 2005 10:52 PM PDT

thanx for ya'll suggestions.

i tried to install WinXP too and got a similiar hanging/freezing. And it's
not bad RAM because I've successfully installed Fedora Core 3 on a Dell
Optiplex GX110 (PIII 667MHz) with the same RAM modules.

I'm told the MSI motherboard and/or the 1 GHz CPU was fried before I
received it. So I'm assuming one of those are the actual culprit.

Anyways, the Dell system seems to be running it okay, so I'm gonna stick
with this setup for now (maybe even test the 1GHz CPU in the Dell mobo
later).

Thanks again people

That's not much, the slowest system I keep around is a PII-350
(196MB memory), bought it used some years ago for a few bucks
(ebay). It's just for playing around, but have to admit, it runs
Debian (Sarge) with KDE3 like a charm.;) The key is of course
enough memory, bought it with 128MB and put in a spare 64 MB
stick flying around. IIRC it can't handle more.

I'd look out for something in the lines used if you need a more
powerful box, amazing how many of those systems are sold for more
or less nothing. Not uncommon systems with perfectly working
hardware but a totally broken doze on it are replaced with a new
system (doze preinstalled), just because people are unable to
recover/reinstall the box.

Knoppix 3.8 - Install to HD

Posted: 23 May 2005 02:06 PM PDT

Thanks Jimbo - it was under the Penguin Icon > Configure > Create
PERSISTENT Knoppix Image

It asked me which partition and it seemed to install fine.

Now, my question is how do I get in? When I remove the disk and restart
- I can only choose Windows XP and Windows 98.

How do I get into Knoppix, and if possible - How do I add Knoppix into
this list?

SeLinux: syslogd cannot access /var/run? Needs nfs_t:dir search?

Posted: 22 May 2005 04:09 PM PDT

I just found the cause of this problem. Reiserfs and selinux combined
do not work, but support for this combination will appear in the
upcoming linux kernel 2.6.12.

The problem is that selinux relies on "xattr" file attributes, and in
reiserfs, xattr attributes are stored in separate files. As the selinux
code tries to access the xattr attributes of a file, selinux is
triggered again to allow or deny access to the xattr file. This leads
to a bad deadlock.

In order to work around the deadlock, the policies distributed with
fedora contain a mapping that maps all files on reserfs systems to
system_u:object_r:nfs_t. This is where the "nfs_t" comes from. This
mapping is applied to all files without accessing any xattr attributes
of the files.

However, the ls -Z option does access the xattr attributes of the files
as stored in the fs, and shows them. Similarly, the selinux programs to
label or relabel the file systems do set xattr attributes of the files
without regard to this mapping. In this way, when investigating the
problem, I could not see where the "nfs_t" came from. The files
appeared to have the correct attributes.

While waiting for the next kernel version to appear as an official
fedora rpm package, I have:

1. Installed selinux-policy-targeted-sources and checkpolicy
2. Run "dmesg | grep 'audit.*denied' | audit2allow
3. Added the output to
/etc/selinux/targeted/src/policy/domains/program/syslogd.te
4. In /etc/selinux/targeted/src/policy, run "make" and "make reload"
5. Run service syslogd restart

6. Repeated steps 2-5 until syslogd starts cleanly and no new audit
messages appeared.

This is quite clumsy, because as soon as syslogd gets a new permission,
it fails on the next operation. Many rounds are required.
A couple of other daemons also need access to /var, and so more rounds
are required.

There is a better approach, to set selinux in permissive mode where all
accesses are permitted, but also logged. This log can be fed into
audit2allow to generate the list of permissions required to run in
non-permissive mode. This is still not perfect if a daemon does certain
accesses only in particular circumstances. But I have not yet
investigated how this is done.

Anyway, the permissions I have ended up with so far are:

allow dhcpd_t nfs_t:dir { add_name remove_name search write };
allow named_t nfs_t:dir { add_name remove_name search write };
allow ndc_t nfs_t:dir { search };
allow ntpd_t nfs_t:dir { add_name search write };
allow portmap_t nfs_t:dir { add_name search write };
allow syslogd_t nfs_t:dir { add_name remove_name search write };
allow dhcpd_t nfs_t:file { append create getattr link lock read
rename unlink write };
allow named_t nfs_t:file { append create getattr lock read unlink
write };
allow ntpd_t nfs_t:file { append create getattr lock read write };
allow portmap_t nfs_t:file { append create getattr lock read };
allow syslogd_t nfs_t:file { append create getattr ioctl lock read
unlink write };

When the next kernel arrives I will have to remove the mapping to
nfs_t. The mapping is in the file genfs_contexts in the src/policy
directory. Run make and make reload as above.

When a new version of the rpm package selinux-policy-targeted appears,
you should probably remove the *-sources package, or else the new
policy will not be installed. (I guess it will appear as *.rpmnew.)

Regards.

If you need to setup a dialup connection try pppsetup or

If it is an external modem (a real modem) and you need fax
