Lentil performs backups. Its backup script needs further investigation to determine exactly how it works.
Network Configuration
Hostnames: lentil.unh.edu, lentil.farm.physics.unh.edu
Currently connected to the unh and farm networks via the switch and VLAN.

Access Configuration
/etc/security/access.conf Any valid user can log into lentil from any machine on the Internet.
Backup Configuration
Location of Backups
/mnt/npg-daily/34/
All backup related scripts are:
/etc/auto.npg-daily /usr/local/bin/rsync_backup.pl /etc/cron.daily/0rsync_backup /usr/sbin/vgcfgbackup /etc/rsync-backup.conf
/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
[usr_local]
path = /usr/local
comment = unpackaged software
[opt]
path = /opt
comment = unpackaged software
[etc]
path = /etc
comment = conf files
[var]
path = /var
comment = user and system storage
SNMP Configuration
/etc/snmp/snmpd.conf Copied from Pepper.
Smartd Configuration
This configuration file will run smartd to check the status and performance of all the hard drives.
/etc/smartd.conf
# *SMARTD*AUTOGENERATED* /etc/smartd.conf # Remove the line above if you have edited the file and you do not want # it to be overwritten on the next smartd startup. # Sample configuration file for smartd. See man 5 smartd.conf. # Home page is: http://smartmontools.sourceforge.net # The file gives a list of devices to monitor using smartd, with one # device per line. Text after a hash (#) is ignored, and you may use # spaces and tabs for white space. You may use '\' to continue lines. # You can usually identify which hard disks are on your system by # looking in /proc/ide and in /proc/scsi. # The word DEVICESCAN will cause any remaining lines in this # configuration file to be ignored: it tells smartd to scan for all # ATA and SCSI devices. DEVICESCAN may be followed by any of the # Directives listed below, which will be applied to all devices that # are found. Most users should comment out DEVICESCAN and explicitly # list the devices that they wish to monitor. # DEVICESCAN # First (primary) ATA/IDE hard disk. Monitor all attributes # /dev/hda -a # Monitor SMART status, ATA Error Log, Self-test log, and track # changes in all attributes except for attribute 194 # /dev/hdb -H -l error -l selftest -t -I 194 # A very silent check. Only report SMART health status if it fails # But send an email in this case /dev/hde -H -m root /dev/sda -d ata -H -m root /dev/sdb -d ata -H -m root /dev/sdc -d ata -H -m root # First two SCSI disks. This will monitor everything that smartd can # monitor. # /dev/sda -d scsi # /dev/sdb -d scsi # HERE IS A LIST OF DIRECTIVES FOR THIS CONFIGURATION FILE # -d TYPE Set the device type to one of: ata, scsi # -T TYPE set the tolerance to one of: normal, permissive # -o VAL Enable/disable automatic offline tests (on/off) # -S VAL Enable/disable attribute autosave (on/off) # -H Monitor SMART Health Status, report if failed # -l TYPE Monitor SMART log. Type is one of: error, selftest # -f Monitor for failure of any 'Usage' Attributes # -m ADD Send warning email to ADD for -H, -l error, -l selftest, and -f # -M TYPE Modify email warning behavior (see man page) # -p Report changes in 'Prefailure' Normalized Attributes # -u Report changes in 'Usage' Normalized Attributes # -t Equivalent to -p and -u Directives # -r ID Also report Raw values of Attribute ID with -p, -u or -t # -R ID Track changes in Attribute ID Raw value with -p, -u or -t # -i ID Ignore Attribute ID for -f Directive # -I ID Ignore Attribute ID for -p, -u or -t Directive # -v N,ST Modifies labeling of Attribute N (see man page) # -a Default: equivalent to -H -f -t -l error -l selftest # -F TYPE Use firmware bug workaround. Type is one of: none, samsung # -P TYPE Drive-specific presets: use, ignore, show, showall # # Comment: text after a hash sign is ignored # \ Line continuation character # Attribute ID is a decimal integer 1 <= ID <= 255 # All but -d, -m and -M Directives are only implemented for ATA devices # # If the test string DEVICESCAN is the first uncommented text # then smartd will scan for devices /dev/hd[a-l] and /dev/sd[a-z] # DEVICESCAN may be followed by any desired Directives.
rc.local Configuration
This script is modified to run commands when the system is done powering on.
/etc/rc.local
#!/bin/sh # # This script will be executed *after* all the other init scripts. # You can put your own initialization stuff in here if you don't # want to do the full Sys V style init stuff. touch /var/lock/subsys/local #This will send the boot.log to npg-admins everytime the pc is started. mail -s "$HOSTNAME Started, Here is the boot.log" npg-admins@physics.unh.edu < /var/log/boot.log
