Hardware Configuration

  • I removed the 3.5" bay as it was bulky and blocked air flow. It was replaced with simple 3.5" to 5.25" bay adapters.
  • Both PCI slots are filled. Bottom PCI slot is the Actiontec PM560LKI modem. Top PCI slot is the D-Link DEF-500TX NIC.
  • Top fan was unplugged as it was determined to not help cooling as power supply cables were blocking airflow. It added 3 watts as measured by the kill-a-watt.
  • LG GH22NP20 DVD burner was placed on the top drive bay.
  • Memory was placed in the first two slots leaving two open slots.
  • The smart fan from the 3.5" bay that I removed was reclaimed and swapped for the rear fan. With this swap, I can now see the fan's RPMs.
  • All cables were tied off and tested to ensure they won't touch and fans or heat sinks.
  • Died with no warning!Seagate ST31500341AS hard drive was placed in the 3rd from the bottom bay with the 3.5" to 5.25" adapters.
  • OS Drive: MKNSSDCL120GB-DX (Serial # MKN1247A0000148853) hard drive was placed in the 3rd from the bottom bay with the 3.5" to 5.25" adapters.
  • DATA Drive: ST2000DL003 (Serial # 5YD3452G) hard drive was placed in the bottom bay with the 3.5" to 5.25" adapters.

BIOS Configuration

  • BIOS was upgraded to version 1602 build date 3/27/09, and I tweaked the following settings in the BIOS:
 Main->Legacy Diskette A: Disabled
 Advanced->Chipset->Internal Graphics->Primary Video Controller: IGFX-GFX0-GPP-PCI
 Advanced->Chipset->Internal Graphics->UMA Fram Buffer Size: 64MB
 Power->APM Configuration->Restore on AC Power Loss: Always On
 Boot->Boot Device Priority->1st Boot Device: SATA
 Boot->Boot Device Priority->2nd Boot Device: CDROM
 Boot->Boot Device Priority->3rd Boot Device: Disabled
 Boot->Boot Settings Configuration->Full Screen Logo: Disabled
 Tools->Express Gate: Disabled

*NOTE* DO NOT DISABLE THE "Memory Hole Remapping" AS YOU WILL LOSE 1GB OF RAM
*NOTE* IGFX = Internal Graphics (aka on board), GFX0 = PCIEx16, GPP = PCIEx1, PCI = PCI

Boot Up Errors

  • I installed AMD64 Debian 6.0.7 / Squeeze and I deselected the "desktop" packages as I want to run headless.

Error 1

  • I was seeing the following error at boot up:
 Your BIOS doesn't leave a aperture memory hole
 Please enable the IOMMU option in the BIOS setup
 This costs you 64 MB of RAM
  • To fix the above message, I added "iommu=noagp,noaperture" to the kernel line. Based on some research and a bunch of googling, it appears this issue is somewhat related to the fact that I don't have an AGP card. Either way, the two values for the iommu kernel parameter mean the following:
 noagp = Don't initialize the AGP driver and use full aperture.
 noaperture = Ask the IOMMU not to touch the aperture for AGP.

Error 2

  • I was also seeing the following error at boot up:
 PCI: Not using MMCONFIG.
  • To fix the above message, I added "pci=nommconf" to the kernel line. Based on some research I understand that the "pci=nommconf" parameter tells the kernel to ignore mmconfig when identifying PCI devices, thus it will use other methods to identify PCI devices such as the BIOS or direct querying. With that said, I checked the all the pci devices with "lspci -v" and they all appear to be detected properly with the "pci-nommconf" parameter.

Error 1 & 2 Solution

  • Tweaks to fix the above boot errors is as follows:
 vim /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet iommu=noagp,noaperture pci=nommconf"

 update-grub

Error 3

  • I then saw the following error:
 Error: Driver 'pcspkr' is already registered, aborting...

Error 3 Solution

  • To fix the above error, I blacklisted snd-pcsp to avoid the conflict during boot, as such:
 vim /etc/modprobe.d/blacklist.conf

  #FLC# Getting rid of error at boot about 'pcspkr'
  blacklist snd-pcsp

Initial Configuration

  • I installed the following packages:
 aptitude install htop rsync ssh
  • Configured sshd to deny remote root login
 vim /etc/ssh/sshd_config
  • Find and change "PermitRootLogin yes" to "PermitRootLogin no", as such:
 PermitRootLogin no

Configuring dial-in server / mgetty / ppp

Server Settings

  • I installed the following packages:
 aptitude install mgetty ppp
  • Querying modem info:
 dmesg | grep "irq = `lspci  | grep Communication | awk '{print $1}' | xargs -n1 -i lspci -v -s {} | grep IRQ | awk -FIRQ\  '{print $2}'`"
 lspci  | grep Communication | awk '{print $1}' | xargs -n1 -i lspci -v -s {} | grep IRQ | awk -FIRQ\  '{print $2}' | xargs -n1 -i grep {} /proc/tty/driver/serial
 cat /proc/interrupts
 cat /proc/tty/driver/serial
  • I determined the modem was on /dev/ttyS1, so I modified initab and uncommented the last line and changed it to ttyS1
 vim /etc/inittab 

T3:23:respawn:/sbin/mgetty -x0 -s 57600 ttyS1
  • Added nasty gram in issue.mgetty
 vim /etc/issue.mgetty

-------------------------
Private server, stay out!
-------------------------
  • Configured PPP, I changed the /AutoPPP/ line as shown below:

vim /etc/mgetty/login.config 

/AutoPPP/ -     a_ppp   /usr/sbin/pppd auth -chap +pap 192.168.0.3:192.168.0.4 login auth debug proxyarp

*NOTE* The first IP is the servers (different from eth) and the second IP is the clients (dial-up)
*NOTE* If I want, I can disable non PAP logins (aka terminals) by changing "/bin/login @" to "/bin/false"

  • Changed the default speed for mgetty
 vim /etc/mgetty/mgetty.config

speed 57600
  • Allowed ppp users
 vim /etc/ppp/pap-secrets
  • Find the section called "Every regular user can use PPP and has to use passwords from /etc/passwd" and change to the following (replace username with actual username, left out here for obvious reaons):
"username"       *       ""      *
  • In order to get routing working, I needed to create the following files:
 vim /etc/ppp/ip-up.local

#!/bin/bash
/bin/echo 1 > /proc/sys/net/ipv4/ip_forward
exit 0

 vim /etc/ppp/ip-down.local

#!/bin/bash
/bin/echo 0 > /proc/sys/net/ipv4/ip_forward
exit 0

 chmod +x /etc/ppp/ip-up.local
 chmod +x /etc/ppp/ip-down.local
 reboot
  • At this point, I can either use a terminal program, such as minicom, to login or I can use ppp

Client Settings

*NOTE* This is *NOT* done on griffin. This is was performed on my lappie that I used as a client to connect to griffen. It's documented here for completeness.
*NOTE* I tried gnome-ppp, but it didn't like my modem for some reason and I didn't care to mess with it at the time as I prefer command line utilities for ease of use via ssh

  • I tested with minicom for fun, then move on to setting up ppp, as such:
 aptitude install ppp pppconfig
  • Configure ppp connection
 pppconfig
  1. Choose "Create Create a connection"
  2. Give it a name, I gave it flc
  3. Choose "Dynamic Use dynamic DNS"
  4. Choose "PAP Peer Authentication Protocol"
  5. Give it the username you defined while editing "pap-secrets" from up above
  6. Password of the usernames account
  7. I left the speed as the default of 115200
  8. I left the default value of "Tone"
  9. Enter the proper phone # of the dial-up server
  10. I selected, no and defined the modem as /dev/ttyUSB0 as I was using my Belkin USB->Serial adapter to a USR Modem
  11. Select "Finished Write files and return to main menu."
  12. Select OK, then "Quit Exit the utility"
  • Now everything was set to connect:
 pon flc
  • I tested ssh into the server's IP 192.168.0.103 and it worked, likewise I tried pinging a server on the network and it responded. I had to set my resolv.conf manually and once I did I was able to, slowly, browse the Internet.
  • To disconnect, use:
 poff flc
  • For logging info, use:
 plog

Headless VirtualBox

  • Get and installed virtual box (not ose as it currently doesn't support RDP for management, which I didn't see any other way to manage as I'm running completely headless)
 wget http://download.virtualbox.org/virtualbox/4.2.10/virtualbox-4.2_4.2.10-84104~Debian~squeeze_amd64.deb
 dpkg -i virtualbox-4.2_4.2.10-84104~Debian~squeeze_amd64.deb
  • Virtual Box wanted some extra packages
 aptitude install libcurl3-gnutls libgl1-mesa-glx libgl1 libpng12-0 libpython2.6 libqt4-network libqt4-opengl libqtcore4 libqtgui4 libsdl1.2debian libxcursor1 libxinerama1 libxmu6 libxt6
  • Setting up the VM
 VBoxManage list vms
 VBoxManage createvm -name "WindowsXP" -register
 VBoxManage modifyvm "WindowsXP" -memory "512MB" -acpi on -nic1 nat
 VBoxManage createhd --filename /share/vm/Windows\ XP\ VM.vdi -size 10240 -register
 VBoxManage modifyvm "WindowsXP" -hda /share/vm/Windows\ XP\ VM.vdi 
 VBoxManage modifyvm "WindowsXP" -dvd /share/Windows.iso 
 VBoxHeadless -startvm "WindowsXP"
  • Remove attached CD
 VBoxManage modifyvm "WindowsXP" -dvd none
  • Port forwarding
 VBoxManage setextradata "<VM NAME>" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/<DESCRIPTIVE NAME>/Protocol" <PROTOCOL>
 VBoxManage setextradata "<VM NAME>" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/<DESCRIPTIVE NAME>/HostPort" <LOCAL/HOST PORT> 
 VBoxManage setextradata "<VM NAME>" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/<DESCRIPTIVE NAME>/GuestPort" <VM/GUEST PORT> 
Example: 
 VBoxManage setextradata "WindowsXP" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/RDP/Protocol" TCP
 VBoxManage setextradata "WindowsXP" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/RDP/HostPort" 13389
 VBoxManage setextradata "WindowsXP" "VBoxInternal/Devices/pcnet/0/LUN#0/Config/RDP/GuestPort" 3389

Windows Guests

  • You need to install the guest additions, mount as such: (then in the guest, go to the dvd and install)
 VBoxManage modifyvm "WindowsXP" -dvd /usr/share/virtualbox/VBoxGuestAdditions.iso

Samba

  • I installed samba to share some miscellaneous files.
 aptitude install samba
 mkdir /share/<some_dir_here_I_aint_tellin>
 chown -R <my_user_account>:<my_group> /share
 vim /etc/samba/smb.conf
  • I changed following options:
   workgroup = asgard
   socket options = TCP_NODELAY
  • I added following options:
   security = user
   guest account = <my_user_account>
  • Add a samba user

UPDATE I changed the "security = user" from above to "security = share" to get Windows to properly mount and then I needed to add a samba user as such: 

   smbpasswd -a ohayden
  • I then added the following share:
[share]
   path = /share/<some_dir_here_I_aint_tellin>
   available = yes
   browseable = yes
   public = yes
   writable = no
   guest ok  = yes
   directory mask = 0775

  • I install the apcupsd package and configured it to call the email_power.sh script below to keep me informed of power outages. Don't forget to have apcupsd load at init.

Final Touch Ups

  • Since this server is going to be 1725+ miles away, I figured it would be best if I ran a burn in test with memtest86+. Why memtest86+ over memtest86? According to wikipedia, the latest version of memtest86 has issues with computer having 4GB of RAM. From wikipedia: "The 3.5 version is known to fail on some (or many, or most) computers with 4 gb of installed memory (the failure results in a spontaneous system reboot soon after the program starts running). The MemTest86+ 2.11 version does not exhibit this behavior."
 apt-get install memtest86+
 cat /usr/share/doc/memtest86+/examples/grub-menu.lst >> /boot/grub/menu.lst
  • Clean up the memtest86+ entry
 vim /boot/grub/menu.lst
  • I ran memtest86+ for 32.5 hours and it had 19 passes all with success. Initial watt usage is about 90 watts.

  • Installed a few more utilities for monitoring and power saving
 apt-get install lm-sensors hddtemp hdparm powertop ethtool
  • Installed even more utilities
 apt-get install screen iputils-arping bwm-ng iftop
  • Added the following to /etc/crontab

Movie Script

This is used for Al to easily move movies he's seen to the old folder.

  • Install tiny/turbo/throttling HTTP server
 apt-get install thttpd
  • Remove the users directory as it's not needed
 cd /var/www

  • Create the cgi-bin directory
 mkdir cgi-bin
  • Create a dummy index.htm to avoid directory listings

  • Modified thttpd config
 vim /etc/thttpd/thttpd.conf
  • I changed following options:
 #FLC#choot
 nochoot
 #FLC#user=www-data
 user=ohayden
  • I restarted thttpd to have the new settings take affect
 /etc/init.d/thttpd restart

NOTE: Setting nochoot and changing to user to my account is a major security risk. However, this is minimized as it's only served on the local lan and is closely monitored. Please DO NOT do the above if you provided wan access, otherwise you're begging to get hacked deservedly so.

Reclaiming Disk Space

Reserved blocks is defaulted to 5% on ext3, which is a bit high for newer drives nowadays. I pushed mine back to 1% to reclaim a bit of space with the following command 

tune2fs -m 1 /dev/sda1

Power Saving

  • Ran sensors-detect for lm-sensors
  • Ran pwmconfig for fancontrol, but it seems to cause the fan to stay at full blast so I deleted the /etc/fancontrol configuration file. I suspect it's conflicting with the BIOS as it appears to want to control the fan. I did figure out that playing with /sys/class/hwmon/hwmon1/device/pwm1 would slow down or speed up the fan by echoing 1 to 255 respectively.
# Enabled for the HDA controller; power down after 10 seconds:
echo 10 > /sys/module/snd_hda_intel/parameters/power_save
# Power down hard drive after 5 minutes:
hdparm -S 60 /dev/sda
# Up kernel caching to 15 seconds:
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs
# Enable laptop mode:
echo 5 > /proc/sys/vm/laptop_mode
# Enable SATA ALPM link power management:
echo min_power > /sys/class/scsi_host/host0/link_power_management_policy
# Enable noatime on filesystem:
mount -o remount,noatime /

NOTE: After testing with a kill-a-watt for a week, the power savings was negligible so I opted not to implement them for now. The only thing I ended up doing was leave one case fan off.
