General Information
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.
ifconfig

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
The configuration file is at /etc/smartd.conf. The smartd.conf does a silent check, which only emails reports if the SMART health status comes back as failed. This smartd.conf will look different from alot of the other computers because it doesn't have a RAID card installed, so each disk is mounted seperately for backups.
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
