Windows 7 SP 1 fresh installed and not updating? svchost stuck at 100% CPU?
PC-WELT-Fix Windows Update not helping? WSUS Offline Update not working?
This HOWTO from skanthak worked
for me:
[...] Download at least the last cumulative (security) update package for Internet
Explorer 8, 3124275 alias MS16-001, and the latest (security) update package for
the Windows Update Client, currently (September 20, 2016) 3161647; the latter is
available only as part of the "July 2016" (optional) update rollup package
3172605. [...]

When using wget with a proxy that requires authentication, special characters
need to be URI encoded, e.g. # becomes %23. Using for example pa##word:
https_proxy='http://username:pa%23%23word@proxy:8080' wget https://google.com
On top of that when using gem the colon seperator between the username and
pasword needs to be escaped, e.g. \::
http_proxy='http://username\:pa%23%23word@proxy:8080' gem fetch hiera-eyaml
Also note, gem will use the http_proxy environemt variable even if it is
connecting to a https:// url.
But when using gem from a puppetlabs installation, e.g.
/opt/puppetlabs/puppet/bin/gem, you must not escape the colon, but use
HTTP_PROXY.
When installing gems into puppetserver 4, pass -p to gem install:
puppetserver gem install -p http://username\:pa%23%23word@proxy:8080 hiera-eyaml
Tired of typing puppet://$server/module/$module/...? Here to the rescue:
module Puppet::Parser::Functions
newfunction(:here, :type => :rvalue) do |args|
"puppet://%s/modules/%s/%s" % [ lookupvar('servername'), lookupvar('module_name'), args[0] ]
end
end
Put it in $module/lib/puppet/parser/functions/here.rb, use with:
file {
ensure => ...
...
source => here('foo.txt');
}
Following this RPi U-Boot Howto .
I setup a
cross compile chroot to
build u-boot for my Raspberry 1:
sudo debootstrap sid sid
sudo chroot sid
dpkg --add-architecture armhf
apt-get update
apt install git-core gcc-arm-linux-gnueabi
cd /tmp
git clone git://git.denx.de/u-boot.git
cd u-boot
export CROSS_COMPILE=arm-linux-gnueabi-
make rpi_defconfig
make -j5 -s
Download the latest
Jessie Lite Image and wrote it
to my SDCARD (/dev/sdb in my case):
cd /tmp
wget https://downloads.raspberrypi.org/raspbian_lite_latest -O raspbian_lite_latest.zip
unzip raspbian_lite_latest.zip
dd if=2016-05-27-raspbian-jessie-lite.img of=/dev/sdb bs=1M
Setup NFS root, copy the Kernel to the tftproot and install u-boot:
cd /tmp
mkdir pi
mount /dev/sdb2 pi
mount /dev/sdb1 pi/boot
mkdir /var/lib/tftpboot/pi
cp pi/boot/kernel.img /var/lib/tftpboot/pi/zImage
cp pi/boot/*.dtb /var/lib/tftpboot/pi/
mv pi/boot/kernel.img{,.old}
cp /tmp/sid/tmp/u-boot/uboot.bin pi/kernel.img
cp -a pi /mnt
umount pi/boot
umount pi
Setup NFS export:
/mnt/pi 10.0.0.1(rw,no_root_squash,async,no_subtree_check)
Configure dhcp:
host pi1 {
hardware ethernet TH:AT:IS:MY:MA:C0;
fixed-address 10.0.0.1;
filename "/pi/boot.scr.uimg";
option root-path "/mnt/pi";
}
Create the boot script that actually loads and boots the kernel
/var/lib/tftpboot/pi/boot.scr:
setenv fdtfile /pi/bcm2708-rpi-b.dtb
setenv tftpblocksize 1024
usb start
tftp ${kernel_addr_r} /pi/zImage
tftp ${fdt_addr_r} ${fdtfile}
setenv bootargs earlyprintk console=ttyAMA0 console=tty1 ip=dhcp root=/dev/nfs rootwait smsc95xx.macaddr=TH:AT:IS:MY:MA:C0
bootz ${kernel_addr_r} - ${fdt_addr_r}
I needed to set my MAC as it would generate a new one on every boot.
Convert boot script to something u-boot can handle:
cd /var/lib/tftpboot/pi
mkimage -A arm -O linux -T script -C none -n boot.scr -d boot.scr boot.scr.uimg
Boot the Pi, interrupt u-boot and
setup it’s environment :
setenv bootcmd 'dhcp; source ${fileaddr}'
saveenv
reset
I havn’t found a way to set config.txt options though.
While trying to install FreeBSD via the bootonly image resulted in
mount failed with error 19
But using
dhcp/tftp servers on Wheezy
packages syslinux, syslinux-common and pxeboot from Jessie
mfsBSD SE USB memstick Image
I was able to install FreeBSD via netboot with ZFS on /.
Copy syslinux files to the tftp root:
cp -r /usr/lib/syslinux/modules/bios /var/lib/tftpboot/syslinux
Download mfsBSD image, gzip and copy to
/var/lib/tftpboot/syslinux/freebsd
Configure pxelinux:
label freebsd
menu label freebsd
kernel memdisk
initrd freebsd/mfsbsd-se-10.0-RELEASE-i386.img.gz
After booting, look for disk and install:
geom disk list
Geom name: ada0
Providers:
1. Name: ada0
zfsinstall -d /dev/ada0 -s 256M -u http://www1.de.freebsd.org/freebsd/releases/i386/10.3-RELEASE/
Exporting configured mail accounts and their aliases from the PSA database to
csv:
SELECT
concat(mail.mail_name,"@",domains.name) AS address,
group_concat(mail_aliases.alias) AS aliases,
mail.account_id
INTO OUTFILE
'/tmp/result.csv'
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
ESCAPED BY '\\'
LINES TERMINATED BY '\n'
FROM
mail,domains,accounts,mail_aliases
WHERE
mail.dom_id=domains.id
AND mail.account_id=accounts.id
AND mail_aliases.mn_id = mail.id
GROUP BY
address
ORDER BY
address;
If you use a global template zone, make sure to not specify global=true on
your satelite, e.g.
object Zone "global" {
}
If you have multiple hosts in one zone …
… upstream of you, it’s HA
… downstream of you, it’s Loadbalancing
