Re: Openfoam
by David Gaden
(First post, am I doing it right?)
I saw you guys were looking at OpenFOAM, and Richard attempted a build but gave up. I suspect this was bad timing - the guys at OpenCFD just patched their repository to accommodate the DSO linking changes (i.e. yesterday). Also, as an (independent) OpenFOAM developer, can I be of assistance?

UEFI installation is non-functional in F16B - grub/grub2
by little.owl
Hi all,
I have decided to install Fedora 16 Beta on my netbook Lenovo Ideapad S205 - an AMD E-350 based system. The laptop has UEFI, without any possibility to use a legacy BIOS mode. The system is supposedly designed for Windows 7 only; the future is coming.
The standard way using the installation DVD (a hybrid image -> USB disk) doesn't work. The installer could be booted and the system installed without any errors and warnings. It doesn't boot in EFI mode, regardless there is an EFI directory. After the installation, the hardisk has GPT layout, without EFI System partition. The UEFI - Phoenix SecureCore Tiano - is not able to load the OS, there is a BIOS Boot partition with grub2 and no boot records in NVRAM.
The EFI installation using the file efidisk.img from the <dvd>/image/ directory doesn't work. The EFI boot image is based on legacy grub and as a result of that (?) Anaconda tries to install both loaders: legacy grub and grub2. There is a conflict during the package dependency resolution and if the installation continues, the final error is "grubby fatal error: unable to find a suitable template". Anaconda creates the EFI System partition, with the correct GUID and flags, but it is HUGE ~9GB, for layout without LVM ~8GB. Yes, GIGABYTES. Why? Me and Microsoft think that 200MB is a good default value, maximum 500MB. There is no boot record in NVRAM and when I install UEFI shell and run grub.efi, which is installed in directory <EFI System partition>/efi/redhat/grub.efi, the loading of the system fails.
In the final attempt I decided to create a basic GPT layout manually, following the Microsoft's recommendation. The EFI System partition is the first one, having size 200MB and all needed flags/GUID. I repeated the UEFI installation, ignoring all errors. After that I uninstalled the legacy grub in the rescue mode. As a fall-back solution I copied UEFI shell to <EFI System partition>/efi/boot/bootx64.efi; the PC now boots reliably to the shell.
The next steps are:
(1) to install grub2 in EFI mode
(2) edit UEFI boot records in NVRAM
At the moment, I am struggling with the first point, grub2 and EFI; I am really tempted to use the legacy grub. When I have some functional grub[2].efi somewhere, I would like to run it from the startup.nsh script and edit EFI boot records using efibootmgr.
I found annoying that in the gdisk is missing in the default installation, including the rescue mode and Live CD; the fdisk is useless for GPT and the [g]parted doesn't allow the precise control over the GPT partitioning.
I should fill bugs, I just need to clarify what is a bug, what is a feature, what is an unimplemented feature, what are my mistakes and if the problems are in anaconda or grub2.
The grub2 and all (U)EFI stuff are completely new for me, so any hints or links are welcome.

Gnome shell memory leak in F16 TC2 ?
by Pratyush Sahay
Hello all,
Have a fully updated F16 TC2. Gnome-shell's memory footprint is ballooning
like anything, making the GUI sluggish. Observed especially after running
system for long hours or when unseen notifications accumulate alot in the
bottom panel. Today, in 7hrs it jumped from 40-50 MB to 430 MB.
Doing a Alt+F2 and 'r' brings gnome-shell back to normal levels. Guess
people have seen it in F15 too earlier [1]. i didnt experience it much with
F15 though.

LUKS type passphrase twice
by Jeronimo
Hi Folks,
I have / and /home luks encrypted, and until today the passphrase was
used to decrypt both partitions, as they are actually the same one.
From now, i have to type twice, one time per partition.
I have read about it, and seems that whenever /etc/rc.local gets
modified it can lead to that behavior.
Any way to get that fixed?
Cheers,

Cannot configure printer that is on a windows server
by Paolo Galtieri
Folks,
I have a printer issue that I cannot figure out what is going on. Here's
the issue:
I run system-config-printer and I select add a network printer. I select
the "Windows Printer via SAMBA" option and enter
TALOFASYSTEMS/TALOFA01/
and click browse. After a few seconds an SMB Browser popup is displayed
with TALOFASYSTEMS as the share name and TALOFA01 as the comment with an
arrow in front of the share name. A couple of seconds later I get an
authentication popup indicating I need to login to TALOFA01, which is the
windows system where the printer is, requiring I enter a username and
password. This is the output from s-c-p
Caught non-fatal exception. Traceback:

The username it fills in is root, the domain name is TALOFASYSTEMS. Trying

Back in the Fedora 12 time frame I had no problems configuring a printer, to
the same system, using samba. Since Fedora 14 I can longer do so.
If I configure the printer on Windows 7 I'm not asked for any authentication
information and no authentication information is configured on the windows
server side.
Anybody have any pointers as to how to configure a printer via samba?
Also my mother, who is running scientific linux, is having the same problem.
I have stopped iptables service and disabled the firewall and it still
fails.
Any assistance is appreciated.
Thanks,
Paolo

fail2ban vs. logrotate
by Mike Wohlgemuth
I've installed fail2ban on Fedora 15 to block repeated failed ssh
connections. It works great up until logrotate kicks in. When it
rotates /var/log/secure then fail2ban stops noticing failed ssh
attempts. Using fail2ban-client to reload the jail fixes the problem,
but it also causes fail2ban to forget all currently banned IP
addresses. I've found scripts online that will allow for extracting the
current bans before reloading, and then applying them again after, but
that seems pretty extreme. I can't help but think I must be missing
something simple that will get fail2ban to notice that the logs have
been rotated. Has anyone else seeing this issue? I see some reports in
bugzilla about fail2ban, but nothing that is definitely this problem.
Thanks

F15 - Apache and PHP
by Steven F. LeBrun
Hi,
For the past month or two, I have been developing a web site on my
laptop using Apache 2.2.21 with PHP 5.3.8 on Fedora 15. Everything was
working as expected until a few days ago. One day, my Apache HTTPD
server stopped processing the PHP code in the files with "php"
extensions, the very files that worked correctly the day before.
I have gone over all the changes that I have made to php.ini (made no
changes to the httpd configuration files). I am not sure what changed
to cause Apache to pass the PHP code in the HTTP response back to the
browser. It is possible that my system was updated using yum via
yumex. There are no signs of errors in the httpd error_log or messages log.
At the moment, my browser is receiving the full PHP files including the
embedded php code.
Any suggestions on how to fix or find the cause of this problem are welcome.

Why the difference ? Perhaps there is an error in one of the update packages ?
