Client Test Configuration

Create a file named .amandahosts in the home directory of the Amanda user on the client. It should contain an entry with the hostname of the Amanda server and the Amanda user on the server:

su - amanda
echo "amanda.example.com amanda" > .amandahosts
exit

Since version 2.5.0, the .amandahosts file also requires strict permissions. Also, the home directory of the Amanda user (containing the .amandahosts file) should be write-protected from modification by any other user:

chown amanda ~amanda ~/.amandahosts
chmod 755 ~amanda
chmod 600 ~amanda/.amandahosts

Create an empty file /var/amanda/amandates and change its ownership to the Amanda user:

mkdir /var/amanda
chown amanda:backup /var/amanda
touch /var/amanda/amandates
chown amanda:backup /var/amanda/amandates

Make the file /var/amanda/dumpdates writable by the Amanda user:

touch /var/amanda/dumpdates
chmod 664 /var/amanda/dumpdates
chgrp backup /var/amanda/dumpdates

If the dumptype for this client uses GNU-tar, then you must create a directory for it. Create the directory, making sure the Amanda user has write permission:

mkdir -p /var/lib/amanda/gnutar-lists
chown -R amanda:backup /var/lib/amanda
exit

xinetd configuration

yum install xinetd

Create /etc/xinetd.d/amanda:

#o Either:
#  - Add this to /etc/xinetd.conf
#  - Or create a new file called /etc/xinetd.d/amanda
#
#o Entry for /etc/inetd.conf:
#  - amanda dgram udp wait backup /usr/sbin/tcpd /usr/lib/amanda/amandad
#
#o Don't forget that:
#  - 'bind' is the ip address of the interface on which the amanda client
#    will respond on.
#  - 'only_from' is the amanda server's ip address that the client will talk
#    to.
#
#o Translation for xinetd:
#
service amanda
{
         socket_type     = dgram
         protocol        = udp
         wait            = yes
         user            = amanda
         groups          = yes
         server          = /usr/local/libexec/amanda/amandad
         bind            = client_ip_address
         only_from       = server_ip_address
}
service xinetd restart

Daemontools configuration
Install netcat from source (Centos 5 RPM no workie!:

cd /extra/src
wget http://internap.dl.sourceforge.net/sourceforge/netcat/netcat-0.7.1.tar.gz
tar zxvf netcat-0.7.1.tar.gz
cd netcat-0.7.1
./configure
make
make install

Make the service directory:

mkdir /var/service/amanda

Create /var/service/amanda/run:

#!/bin/sh
exec /usr/local/bin/setuidgid amanda \
/usr/bin/netcat -l -u -p 10080 \
-e /usr/local/libexec/amandad >/dev/null 2>/dev/null

Make it executable:

chmod 755 run

Create the log service:

mkdir -m 755 log
cd log
wget http://qmail.jms1.net/scripts/service-any-log-run
mv service-any-log-run run
chmod 755 run

Create the symbolic link to start the service:

ln -s /var/service/amanda /service/amanda
