2007-12-15: Formatted the fresh drive and installed all the components in our second Antec case.

New 250 GB drive, with the following partitions:

Using the same script as on archon (just changed the directory to the one I am jusing):

#!/bin/bash
#
# check_nfs_mounts.sh
# quick check if we have our NFS directories mounted... if not... mount them!
# - dlr 2008/11/12
 
MOUNTEDTEST=`df | grep '/mnt/nfs/vault' | wc -l`
 
if [ $MOUNTEDTEST -ne 1 ]; then
  mount /mnt/nfs/vault
fi

Using mdadm, I have the following running from /etc/rc.d/rc.local:

mdadm --monitor --daemonise --mail MY.EMAIL@MY.SERVER --test /dev/md0

Set our clock hourly to nist's time server: /etc/cron.hourly/set_clock_via_network.sh

#!/bin/sh
/usr/sbin/ntpdate time-a.nist.gov >/dev/null 2>&1

Since my mythbox hard drive seems to be dead (that was my dhcp server), I'll attempt to put it on here.

1. Install the dhcpd server:

   yum install dhcp.x86_64

2. Modified my /etc/dhcpd.conf to give out local IPs:

   # dhcpd.conf
   #
   # Configuration file for ISC dhcpd (see 'man dhcpd.conf')
   #
   # archon.lattice.net dhcpd.conf - dlr 20070322 (spring is here!)
    
   # If this DHCP server is the official DHCP server for the local
   # network, the authoritative directive should be uncommented.
   authoritative;
    
   #Sets the domain name and our default DNS servers
   option domain-name                      "lattice.net";
   option domain-name-servers              10.0.0.1, 10.0.0.2;
   option netbios-name-servers             10.0.0.1;
   option netbios-dd-server                10.0.0.1;
   option netbios-scope                    "";
   option netbios-node-type                8;
    
   #Sets the time loan time in seconds before computers must renew thier leases
   default-lease-time                      86400;
   #Set the maximum amount of time a pc can hold a lease for
   max-lease-time                          864000;
    
   # I was told to do this :)
   # ddns-update-style ad-hoc;
   ddns-update-style none;
   ddns-ttl                                86400;
    
   #This is a subnet which the dhcpd server controlls, note the { this is required
   subnet 10.0.0.0 netmask 255.255.255.0 {
     #Sets the network gateway / router
     option routers                        10.0.0.1;
     #Sets the network broadcast address
     option broadcast-address              10.0.0.255;
    
     #Defines a range of ips to be used as leases
     range 10.0.0.100 10.0.0.200;
    
   # specific host definitions
     host david {                           # Set the hostname of the client computer
       hardware ethernet 00:50:8d:ed:aa:dd; # Registers the MAC address of the client computer.
       fixed-address 10.0.0.42;             # This line specifies the IP address for david's computer
     }
     host krysalis {                        #Set the hostname of the client computer
       hardware ethernet 00:10:dc:a1:d3:aa; # Registers the MAC address of the client computer.
       fixed-address 10.0.0.40;             # This line specifies the IP address for christine's computer
     }
     host wirelesslan {                     # Set the hostname of the client computer
       hardware ethernet 00:30:bd:66:4d:b2; # Registers the MAC address of the client computer.
       fixed-address 10.0.0.11;             # This line specifies the IP address for the wireless lan (inside)
     }
    
   }

3. Ran setup and checked the box next to dhcpd.
4. Manually started it normally:

   service dhcpd start

Well, selinux has to go apparently

setup  # and disable it

Need to install the server (it doesn't come with it by default)

mysql-server.x86_64

I also am installing http://www.phpmyadmin.net/, and I needed to install the mysql plug for that

yum install php-mysql.x86_64
yum install php-mbstring.x86_64
service httpd restart

The named.conf file goes here: /var/named/chroot/etc

The directory root where all the files go is /var/named/chroot/var/named

chkconfig named on

Shares go in /etc/exports

Stopping nfs:

service nfslock stop
service nfs stop
service portmap stop
umount /proc/fs/nfsd

Starting nfs:

service portmap start
service nfs start
service nfslock start
mount -t nfsd nfsd /proc/fs/nfsd

For windows sharing, I'm going to set this up like the other machines.

Modified /etc/samba/smb.conf to share up my directory on the local LAN only.

[global]
workgroup = DCGAMER
netbios name = SAGE
# wins support = yes
server string = Sage Samba Server
# don't log, we get hammered from the outside
# log file = /var/log/samba.%m
max log size = 50
interfaces = eth1 lo
hosts deny = ALL
hosts allow = 10.0.0.0/24 127.
security = share

[david]
    comment = David on Sage
    path = /usr/local/home/david/
    public = yes
    only guest = yes
    writable = no
    printable = no

Need to set the smart host for sage to archon (our mail guru)

Edit /etc/mail/sendmail.mc so that MAILHOST is not commented and set to our local IP

m4 sendmail.mc > /etc/mail/sendmail.cf

1. For network monitoring I installed snmp:

   yum install net-snmp.x86_64
   yum install net-snmp-utils.x86_64

2. Edit /etc/snmp/snmpd.conf to contain the following:

   #       sec.name  source          community
   com2sec local     localhost         archcomm
   com2sec mynetwork 10.0.0.0/24       archcomm
   com2sec mynetwork 71.127.151.0/24   archcomm
   
   ####
   # Second, map the security names into group names:
   
   #               sec.model  sec.name
   group MyRWGroup v1         local
   group MyRWGroup v2c        local
   group MyRWGroup usm        local
   group MyROGroup v1         mynetwork
   group MyROGroup v2c        mynetwork
   group MyROGroup usm        mynetwork
   
   ####
   # Third, create a view for us to let the groups have rights to:
   
   #           incl/excl subtree                          mask
   view all    included  .1                               80
   
   ####
   # Finally, grant the 2 groups access to the 1 view with different
   # write permissions:
   
   #                context sec.model sec.level match  read   write  notif
   access MyROGroup ""      any       noauth    exact  all    none   none
   access MyRWGroup ""      any       noauth    exact  all    all    none
   
   ########  and down the road...
   
   syscontact "david <david@lattice.net>"
   syslocation "Ellicott City, MD USA"

3. Verify that the daemon is up at running in our run levels:

   chkconfig named on

4. Start the service:

   service snmpd start

1. Modify your firewall rule so that ftp can see into your home directory:

   /usr/sbin/setsebool -P ftp_home_dir 1

2. Modify /etc/vsftpd/vsftpd.conf so that at the bottom, you have this:

   pam_service_name=vsftpd
   userlist_deny=NO                   # <- so the list is ONLY who CAN ftp in
   userlist_enable=YES 
   userlist_file=/etc/vsftpd.ftpusers # <- let the daemon know exactly the list you are using
   tcp_wrappers=YES
   log_ftp_protocol=YES

3. Add just the users you want to ftp into the system to /etc/vsftpd.ftpusers
4. Enable ftpd:

   chkconfig vsftpd on
   service vsftpd start

1. Install the cronjob yum update:

   yum install yum-cron.noarch

2. Turn on the cron job for our run levels:

   chkconfig yum-cron on

3. Kickstart the service manually:

   service yum-cron start

Remove this as it appears to be broken

yum remove yum-updatesd

Modify the network settings for the second ethernet by directly modifying the startup script.

 vi /etc/sysconfig/network-scripts/ifcfg-eth1

Modify /etc/resolv.conf to add archon as our primary dns.

My old mst3k 500GB drive is

Vendor: ATA       Model: SAMSUNG HD501LJ   Rev: CR10
500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       60801   488384001   83  Linux

The new Seagate drives are

Vendor: ST350063  Model: 0NS               Rev: H
Type:   Direct-Access                      ANSI SCSI revision: 02
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

I had the old Hitachi 500gb drive that used to be my MST3k repository die, so I think I'm going to go with a clean and unencrypted raid this time around (now that I know how to do it, I'd rather have the speed).

Creation Date: — David Lloyd Rabine 2008/10/16 06:45

1. Turned off the server, and swapped out the Hitachi with the new Seagate ES.2 500gb drive.
2. Create a partition on the new drive (just take up the entire disk) with fdisk on each as the primary partition.
3. Use mdadm to create the array

   mdadm --create /dev/md0 --chunk=64 --level=5  --name=spaceraid --raid-devices=5 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1

4. Format the device as ext3:

   mkfs.ext3 -m 0 /dev/md0 -L /space # I am not leaving any reserve since this is a data drive only

5. Mount the raid

   mount /dev/md0 /mnt/raid/space/

Creation date: — David Lloyd Rabine 2008/02/12 09:49

A lot of this is coming directly from here and the man page for mdadm.

1. Installed the 4 Seagate drives in the removable cartridges, and the Hitachi disk (as my 5th disk) in the main case below the root drive (gray SATA cable).
2. Create a partition on each drive (just take up the entire disk) with fdisk on each as the primary partition.
3. Use mdadm to create the array

   mdadm --create /dev/md0 --chunk=64 --level=5  --name=spaceraid --raid-devices=5 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1

4. Create a mapping from our device to an encrypted device: (found this cryptsetup stuff here)

   cryptsetup -c aes -h sha512 -y create chaoticspace /dev/md0  # and you will want to supply a password (good one)

5. Create our partition on the encrypted device:

   mkfs.ext3 -m 0 /dev/mapper/chaoticspace -L /space # I am not leaving any reserve since this is a data drive only

6. Make a directory to mount to:

   mkdir /mnt/raid/
   mkdir /mnt/raid/space

7. Symbolically link that to our root directory:

   ln -s /mnt/raid/space /space

8. Manually mount our new data castle:

   mount /dev/mapper/chaoticspace /mnt/raid/space

To add keys:

cryptsetup luksAddKey /dev/md0

To mount: (after a reboot you're going to need to manually mount the drive (with password))

1. Assemble the software raid:

   mdadm --assemble /dev/md0 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1

2. Map the device:

   cryptsetup -c aes -h sha512 create chaoticspace /dev/md0

3. Mount the encrypted partition (via the mapper) to our mount point:

   mount /dev/mapper/chaoticspace /mnt/raid/space

To unmount:

umount /mnt/raid/space  
cryptsetup remove chaoticspace

Some notes I got from here:

After you’ve created the array it’s time to encrypt it. Running the following command will create /dev/mapper/storage which is effectively your encrypted device.

# cryptsetup -c aes -h sha512 -y create storage /dev/md0

You will now need to create the file system. If you plan on resizing the array at any time I would recommend you use reiserfs.

# mkreiserfs /dev/mapper/storage

Finally you will need to mount it

# mkdir /mnt/storage
# mount /dev/mapper/storage /mnt/storage

After a shutdown or restart you will need to mount the storage manually. The mdadm init script should have assembled the array, you can check by viewing /proc/mdstat. If your raid device hasn’t assembled you can do it with this command :

# mdadm --assemble --run /dev/md0 /dev/sdb1 /dev/sdc1 /dev/sdd1

Now you’ll need to run cryptsetup and mount the device. Notice the command is silightly different to the command issued when creating the encrypted device :

# cryptsetup -c aes -h sha512 create storage /dev/md0
# mount /dev/md0 /mnt/storage

Just use your slackware box with the package that is in the 'extras' directory (bit torrent and bit tornado so you can use that headless client in screen). I need to compile and install a fair number of packages to get this to work.

I wanted to run the SpeakEasy speed test page, so I wanted to install a browser.

yum install firefox
yum remove firefox.x86_64  # the 64 bit version won't do flash

This requires x11 (and flash too)

Go to adobe's download site, and install the repository for adobe / flash

yum install flash-plugin.i386

I edited /etc/yum.repos.d/adobe-linux-i386.repo afterwards and disabled it by default

yum install gcc
yum install compat-gcc*

I can't seem to live without jed. Need to modify /etc/yum.conf to not check gpg keys for this to work.

wget ftp://rpmfind.net/linux/fedora/core/development/x86_64/os/Fedora/jed-0.99.18-5.fc6.x86_64.rpm
yum localinstall jed-0.99.18-5.fc6.x86_64.rpm

yum install lynx

For hatter, a nwn server

I compiled these libraries on the 32 bit sage before he died.

cd /
tar -zxvf /tmp/mysql_for_nwn.tgz  # md5sum = 1ef1a9e95a2c6c759b6da21d5298d681
yum install compat-libstdc*

1. Since this has become the main server, I migrated the servervault over using this command:

   rsync -va --checksum /mnt/nfs/vault/nwn/servervault/ /usr/local/home/nwn/servervault/

2. Modified /etc/exports to share up the drive for writing (since the other server will need to write here):

   # WARNING!  Sage is currently WRITING TO /usr/local/home so DO NOT REMOVE or DISABLE NFS!!!
   # - dlr 20080212 (primary voting day!)
   /usr/local/home              10.0.0.1(rw,no_root_squash,async,subtree_check)

3. Enable NFS on bootup:

   chkconfig nfs on

4. Restart NFS daemon:

   service nfs restart

5. Mount that drive on archon with the following entry to /etc/fstab:

   # DO NOT REMOVE without first shutting down nwn server!  It is writing to this directory
   10.0.0.2:/usr/local/home   /mnt/nfs/sage/local/home  nfs     defaults,rw,soft        0       0

6. Modified both nwn.ini to point to the same server vault:

   ### archon ### 
   SERVERVAULT=/mnt/nfs/sage/local/home/nwn/servervault
   ### sage   ###
   SERVERVAULT=/usr/local/home/nwn/servervault

Found another package on DAG repository

wget http://dag.wieers.com/rpm/packages/pine/pine-4.64-3.el5.rf.x86_64.rpm
yum localinstall pine-4.64-3.el5.rf.x86_64.rpm

Need screen to run the servers in the background.

yum install screen

yum groupinstall "X Window System"

Got to have my xterm… and you need xauth installed or else it won't do the X11 forwarding.

yum install xterm
yum install xauth

Here is a way to add the users from a root console:

adduser -u UID USERNAME -g GROUP -s SHELL
