[Bug 505916] Re: UDHCPC not fetching lease from Windows DHCP server

2010-03-02 Thread Kai Pastor
In my case, it was completely impossible to get a DHCP lease - not even
the first (and only) terminal. The context is a large network with (I
suppose) Windows DHCP servers. It took me a while to get to the solution
indicated in the bug report.

Removing -c '' from the script solves the problem. Now I tested -c
"LTSP-i386" and found that it works, too.

While talking about client ID, I would like to draw your attention to a
line above the udhcpc call:

clientid_param=${clientid:+"-r $clientid"}

What I dislike is the inconsistency that the kernel command-line
parameter "clientid" is used for udhcpc parameter "Request IP address".

[Bug 182960] Re: Please set memory limits by default

2009-08-31 Thread Kai Pastor
Like Steve, I used to think that "the Linux kernel will kill off the
process responsible if it sees that too much memory is being used". But
just two days ago on our Jaunty server with lots of GB RAM and no swap,
a number of system processes were killed during a long-running memory-
consuming calculation, including dbus-daemon, syslogd, console-kit-
daemon. Although the server happily responded to ping, I couldn't login
neither through ssh nor at the console. In the end I was forced to
perform a hard reset.

It looks to me like there is a difference in the behaviour between a)
the system going out of memory and b) a process reaching its memory
limit. In case a) - i.e. no limit - the process to be killed is selected
according to some score.

Attached is a screenshot from the remote access console.

[Bug 505916] Re: UDHCPC not fetching lease from Windows DHCP server

2010-03-06 Thread Kai Pastor
Hi Gadi,

I share Robert's concerns. In fact, it took me hours to find out why
udhcpc is normally working but not with LTSP. IMO, most DHCP setups rely
on MAC address only, and udhcpc is working fine here unless forced to
send an empty ID.

After trying to find out what the client ID is good for, I don't see the
point of specifying an empty client ID as default. Clients are required
to have unique IDs. (It's interesting to see that my clients  are
working now although they are sending the same ID.)

-Kai

[Bug 1019252] Re: Crash in crypto_cert_subject_alt_name when connecting

2012-10-02 Thread Kai Pastor
It is not clear to me what changing the security means. The bug itself
is not neccessarily a security issue. The workaround might be. If HTTPS
doesn't work, would anyone suggest HTTP for online banking?

It's really time for a maintainer to look at the issue.

[Bug 1019252] [NEW] Crash in crypto_cert_subject_alt_name when connecting

2012-06-29 Thread Kai Pastor
Public bug reported:

Release: Ubuntu 12.04 LTS
Package: libfreerdp1 (1.0.1-1ubuntu2.1)

I observed crashes in crypto_cert_subject_alt_name() when connecting to
some hosts with remmina or xfreerdp. The particular DNS name is actually
realized by a cluster of machines, and this is reflected in the
certificate.

It seems to me that crypto_cert_subject_alt_name(...) allocates memory
for "int** lengths" as an array of pointers to integer, but not for the
integers themselves. After adding the additional memory allocation, I
had no more crashes at that point. (I must admit that I didn't check
whether/where the allocated memory gets released.)

I suppose this is not a bug in remmina but rather a bug in freerdp:

https://bugs.launchpad.net/ubuntu/+source/freerdp/+bug/1019252

That bug report [and patch !] has not yet gained any attention or

Since a few days only (Gnome Shell 3.2? New maximus release?), I also
see such an effect. It only happens with maximized windows that are
undecorated by maximus. In addition to the original report there is also
a clipping at the top of the window here.

[Bug 524281] Re: Tens of wakes per second in "[kernel scheduler] Load balancing tick" on Core 2 Duo even with only 1 core enabled

2011-04-29 Thread Kai Pastor
Only a few weeks ago I started looking for the root cause of my laptop's
noise and heat. I used Ubuntu Lucid 10.04 on a dual core laptop and
eventually found this bug.

I tried newer kernels from 
https://launchpad.net/~kernel-ppa/+archive/ppa?field.series_filter=lucid
Unfortunately, experience and reports 
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/760131) show that 2.6.38 
kernels introduce new problems.

I now switched to the latest 2.6.37 from that PPA: This configuration
appears to be the most silent in terms of powertop and fan noise in my
experience.

I'm really disappointed that the orginal issue has not yet been solved
for LTS release users, more than one year after reporting. Doesn't it
affect commercial clients (http://www.h-online.com/open/news/item/LVM-
insurance-company-switches-10-000-systems-to-
Ubuntu-10-04-LTS-1233194.html), too?

[Bug 513423] Re: cannot disable fbcon even when not requried by hw drivers

2010-06-17 Thread Kai Pastor
I faced a slow console in a Hyper-V/Ubuntu 10.04 environment. Simply
blacklisting fbcon doesn't work indeed. To really prevent fbcon from
being loaded, you must configure a placebo modprobe install action. So
this is the solution:

+0200
@@ -0,0 +1,2 @@
+install fbcon /bin/false

Don't forget to update your initramfs.
