Currently has ethernet cable to switch, accessing outside world via the VLAN functions of the switch.


/etc/sysconfig/network-scripts/ifcfg-farm

/etc/sysconfig/network-scripts/ifcfg-lo

DEVICE=lo
IPADDR=127.0.0.1
NETMASK=255.0.0.0
NETWORK=127.0.0.0
# If you're having problems with gated making 127.0.0.0/8 a martian,
# you can change this to something else (255.255.255.255, for example)
BROADCAST=127.255.255.255
ONBOOT=yes
NAME=loopback

Access Configuration

/etc/security/access.conf

# NPG Config:
# Allow direct root logins only from console and einstein
+ : root : LOCAL einstein.unh.edu einstein.farm.physics.unh.edu lentil.unh.edu lentil.farm.physics.unh.edu

# Allow only administrators
- : ALL EXCEPT domain_admins : ALL

Backup Configuration

/etc/rsync-backup.conf

# Backups are 'pull' only.  Too bad there isn't a better way to enforce this.
read only       = yes

# Oh for the ability to retain CAP_DAC_READ_SEARCH, and no other.  
#uid            = root
# XXX There seems to be an obscure bug with pam_ldap and rsync whereby 
# getpwnam(3) segfaults when (and only when) archiving /etc.  Using a numeric
# uid avoids this bug.  Only verified on Fedora Core 2.
uid             = 0

# There's not much point in putting the superuser in a chroot jail
# use chroot    = yes

# This isn't really an effective "lock" per se, since the value is per-module,
# but there really ought never be more than one, and it would at least 
# ensure serialized backups.
max connections = 1
