[Bug 584048] Re: kvm images losing connectivity w/bridged network

2011-04-10 Thread Derek Simkowiak
I have the same 4-second bridge freeze when using LXC containers and
lxc-start or lxc-stop.  (I am using a custom script to create my LXC
containers.)  I saw the reference to this above:

https://www.redhat.com/archives/libvir-list/2010-July/msg00450.html

I changed my custom script from this:

MACADDR=00:16:3e:`head /dev/urandom | md5sum | sed -r
's/^(.{6}).*$/\1/; s/([0-9a-f]{2})/\1:/g; s/:$//;'`

...to this:

MACADDR=fe:16:3e:`head /dev/urandom | md5sum | sed -r
's/^(.{6}).*$/\1/; s/([0-9a-f]{2})/\1:/g; s/:$//;'`

...and now the freezing is gone.

Since this is my own custom script, I'm not sure what package it would
belong to.  Just be aware that this is a fundamental bridge issue and
not limited to libvirt, KVM.  It shows up with LXC and probably any
other system where you add a new MAC.

[Bug 673705] Re: running guests freeze when a guest is powered down

2011-04-10 Thread Derek Simkowiak
This bug is probably a duplicate issue as this:

https://bugs.launchpad.net/ubuntu/maverick/+source/qemu-kvm/+bug/584048

The problem is with Linux bridging.  When adding or removing a MAC
address (like for KVM, VirtualBox, or even LXC) then if the bridge
changes its MAC, this symptom happens.  See comment #60 at the URL
above, and also see this:

https://www.redhat.com/archives/libvir-list/2010-July/msg00450.html

The workaround is to use a MAC address that starts with fe (or any
high really high number) for your guests.  This causes the kernel to
default to the hardware MAC for the bridge.

[Bug 578930] Re: qemu-kvm: ksmd should have a less CPU-hogging default config

2010-12-31 Thread Derek Simkowiak
I'm getting burned by this too, and I disagree with Mr. Kirkland's
assertion that Ubuntu should just use the upstream default.

There are many, many Ubuntu packages which alter the upstream default
to make Ubuntu a more user-friendly experience.  One could even argue
that Ubuntu's best feature is that it changes the upstream defaults of
the world to be something that actually works for human beings.

Please, set this to a reasonable value (200ms?).  As has been pointed
out, the upsteam default is not even considered a reasonable value by
the upstream maintainers.

Ethically speaking, this bug is causing more CPU power consumption (and
thus, global warming) for absolutely no reason whatsoever.

[Bug 563805] Re: mount.cifs won't mount shares; set uid bit not set

2010-05-28 Thread Derek Simkowiak
I disagree with Dietmar's comment #5, which says that 9.10 didn't
have the setuid bit.

Here is my Ubuntu 9.10:

r...@cst6:~# ls -la /bin/mount /sbin/mount.cifs 
-rwsr-xr-x 1 root root 78096 2009-10-22 21:28 /bin/mount
-rwsr-xr-x 1 root root 36296 2010-03-22 15:27 /sbin/mount.cifs

Here is my Ubuntu 10.4:

r...@cst5:/etc/samba# ls -la /bin/mount /sbin/mount.cifs
-rwsr-xr-x 1 root root 82256 2010-03-22 10:57 /bin/mount
-rwxr-xr-x 1 root root 35648 2010-04-09 10:38 /sbin/mount.cifs

As an aside, I see that /sbin/mount.nfs are still set to be setuid
(in Ubuntu 10.4):

r...@cst5:/etc/samba# ls -la /sbin/mount.nfs
-rwsr-xr-x 1 root root 94544 2010-03-23 23:18 /sbin/mount.nfs

[Bug 551655] Re: open-whois.org is cybersquatted and its rules should be removed from Spamassassin

2010-04-19 Thread Derek Simkowiak
If I understood Mathias' comment, he just wants somebody to do steps one
and two of the update procedure to justify backporting this bug.

So, here goes:

Step 1: The bug is fixed in the latest branch, and it is flagged fixed
released (as per above).  Done.

Step 2: I am updating the bug description with the required information
below.

Step 2.1: The impact is that users of 8.04 are getting false positives
from SpamAssassin.  I'm seeing it on an eBox system (eBox is an email
system based on Ubuntu that includes SpamAssassin).

Step 2.2: The bug was addressed as per this bug report.  (See above.)

Step 2.3: Patch: I don't have one, sorry.  The patch is just to remove
all the open-whois.org from /usr/share/spamassassin/72_active.cf ; the
patch used above should suffice.

Step 2.4: To repro the bug: let SpamAssassin filter a mail and flag it
(as per defaults).  You'll see a header like:

X-Spam-Status: No, score=2.431 required=5
tests=[DNS_FROM_OPENWHOIS=2.431]

Once the fix is in place the DNS_FROM_OPENWHOIS rule (and all other
open-whois.org rules) should be gone.


Step 2.5: I don't see how a regression could inadvertently be affected.  The 
open-whois.org service is dead, the domain has been taken by a squatter, and 
100% of all SpamAssassin installs should have these rules removed.


I hope the lack of a patch won't prevent this from getting backported.  I'm 
as excited about 10.4 as anyone, but I won't be upgrading my email systems for 
several weeks or months.  (The OpenLDAP upgrade is broken, due to cn=config and 
bugs like #364531, so moving from 8.04 to 10.4 for my email systems will be a 
huge investment of time.)


Thank You,
Derek Simkowiak

[Bug 442498] Re: openldap install bare bones need default DIT separate package

2010-04-08 Thread Derek Simkowiak
In my opionion, the new (useless) slapd package should not have shipped
until the accompanying slapd-dit was ready.  It basically broke LDAP for
everyone but experts, and now Mathias doesn't have time to fix it.

Mathias, can you make slapd-dit a priority?  It's been several months
since a usable slapd has been available for Ubuntu.

** Changed in: openldap (Ubuntu)
   Status: Triaged = Confirmed

[Bug 253937] Re: Local login fails without LDAP server

2010-02-04 Thread Derek Simkowiak
Same thing here on Ubuntu 9.10.

Here is a (possibly) relevant nss_ldap thread:

http://old.nabble.com/No-timeout-for-nss_ldap--td14576190.html

Unfortunately, that thread ends with I am looking at fixing this now and 
providing some time outs on the soft
path as well. Will keep you informed.  That was back in 2008.

In my opinion this is an important bug.  One of the major reasons for
using LDAP+nss is for high availability in corporate networks... and
this bug breaks that completely.

[Bug 442498] Re: karmic openldap cut-to-bone-and-beyond install, why ????

2009-12-16 Thread Derek Simkowiak
*** This bug is a duplicate of bug 463684 ***
https://bugs.launchpad.net/bugs/463684

Please, provide a working default configuration with the common schemas
(inetOrgUser, sambaUser, maybe virtual mail domains).

Do we really need to argue the benefits an easy-to-install network LDAP
server?  As of 9.04 the client installation was very straight-forward...
but right now the fastest way to get a usable Ubuntu LDAP server is to
install eBox, which comes with hundreds of megs of stuff that we really
don't need.

Even though I know how to configure a slapd server by hand, doesn't mean
I want to waste my time doing it.

The latest 9.04 package 4.76-0ubuntu4 is still broken.

Can we get a backport?  I'm not moving to 9.10 because of all the new
bugs it introduced... (I can't use 8.04 LTS because I need some of the
newer 9.04 packages.)
