Installasjon

daemontools og ucspi-tcp

1. daemontools

   Se http://cr.yp.to/daemontools/install.html.

   Create a /package directory:

   mkdir -p /package
   chmod 1755 /package
   cd /package
   

   Unpack the daemontools package:

   gunzip daemontools-0.76.tar
   tar -xpf daemontools-0.76.tar
   rm daemontools-0.76.tar
   cd admin/daemontools-0.76
   

   En liten endring:

   cd src
   cp conf-cc conf-cc.orig
   echo gcc -O2 -include /usr/include/errno.h > conf-cc
   cd ..
   

   Compile and set up the daemontools programs:

   package/install
   

2. ucspi-tcp

   Se http://cr.yp.to/ucspi-tcp/install.html

   Unpack the ucspi-tcp package:

   gunzip ucspi-tcp-0.88.tar
   tar -xf ucspi-tcp-0.88.tar
   cd ucspi-tcp-0.88
   

   En liten endring:

   cp conf-cc conf-cc.orig
   echo gcc -O2 -include /usr/include/errno.h > conf-cc
   

   Compile the ucspi-tcp programs:

   make
   

   As root, install the ucspi-tcp programs under /usr/local:

   make setup check
   

qmail

1. hent source:

   wget http://www.netqmail.org/netqmail-1.05.tar.gz

2. Opprett brukere og grupper:

   groupadd nofiles
   useradd -g nofiles -d /var/qmail/alias alias
   useradd -g nofiles -d /var/qmail qmaild -s /nonexistent
   useradd -g nofiles -d /var/qmail qmaill -s /nonexistent
   useradd -g nofiles -d /var/qmail qmailp -s /nonexistent
   groupadd qmail
   useradd -g qmail -d /var/qmail qmailq -s /nonexistent
   useradd -g qmail -d /var/qmail qmailr -s /nonexistent
   useradd -g qmail -d /var/qmail qmails -s /nonexistent

3. Opprett kataloger og linker:

   mkdir /var/qmail
   if [ -d /usr/man ]; then
      ln -s /usr/man /var/qmail/man
   elif [ -d /usr/local/man ]; then
      ln -s /usr/local/man /var/qmail/man
   fi
   mkdir /etc/qmail 
   ln -s  /etc/qmail /var/qmail/control
   ln -s /usr/sbin /var/qmail/bin
   
   mkdir -p /var/qmail/supervise/qmail-send/log
   mkdir -p /var/qmail/supervise/qmail-smtpd/log
   
   chmod +t /var/qmail/supervise/qmail-send
   chmod +t /var/qmail/supervise/qmail-smtpd
   
   mkdir -p /var/log/qmail/smtpd
   chown -R qmaill /var/log/qmail

4. Pakk ut kildekode og kompiler:(endret med netqmail-1.06)
   

   cd /usr/local/src
   tar zvxf <DOWNLOADDIR>/netqmail-1.05.tar.gz
   cd netqmail-1.05
   ./collate.sh
   
   cd /usr/local/src/netqmail-1.05/netqmail-1.05
   make setup check
   
   ./config-fast <hostname>

5. Lag boot-script, /var/qmail/rc:

   #! /bin/sh
   
   # Using stdout for logging
   # Using control/defaultdelivery from qmail-local to deliver message by default
   
   DELIVERY=`cat /etc/qmail/defaultdelivery`
   if [ -z "$DELIVERY" ]; then
      echo "/etc/qmail/defaultdelivery is empty or does not exist" 1>&2
      exit 1
   fi
   
   exec env - PATH="/var/qmail/bin:$PATH" qmail-start "$DELIVERY"

   Fila kan også hentes her.

   Så:

   echo "./Mailbox" > /etc/qmail/defaultdelivery
   chmod 644 /etc/qmail/defaultdelivery
   chmod 755 /var/qmail/rc

   ./Mailbox kan også være ./Maildir/
6. Lag oppstartscript

   Lag ei fil /var/qmail/bin/qmailctl:

   Lag link og gjør scriptet eksekverbart:

   chmod +x /var/qmail/bin/qmailctl
   ln -s /var/qmail/bin/qmailctl /usr/local/sbin
   ln -s /var/qmail/bin/qmailctl /etc/init.d/qmail
   chkconfig --add qmail

7. /var/qmail/supervise/qmail-send/run:

   #!/bin/sh
   exec /var/qmail/rc

8. /var/qmail/supervise/qmail-send/log/run:

   #!/bin/sh
   exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t /var/log/qmail

9. /var/qmail/supervise/qmail-smtpd/run:

   OBS: Verdien spesifisert (max minne) til  softlimit kommandoen må muligens økes avhengig av operativsystem og hardware. Dersom forsøk på å koble seg til port 25 feiler, eller andre maskiner ikke klarer å sende mail kan de t være at du ser meldinger som:

     /usr/local/bin/tcpserver: error while loading shared libraries:
     libc.so.6: failed to map segment from shared object: Cannot
     allocate memory
   

   prøv å øke verdien til 3000000 eller 4000000
10. Lag fila concurrencyincoming:

    echo 20 > /etc/qmail/concurrencyincoming
    chmod 644 /etc/qmail/concurrencyincoming

11. /var/qmail/supervise/qmail-smtpd/log/run:

    #!/bin/sh
    exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t /var/log/qmail/smtpd

12. Gjør filene eksekverbare:

    chmod 755 /var/qmail/supervise/qmail-send/run
    chmod 755 /var/qmail/supervise/qmail-send/log/run
    chmod 755 /var/qmail/supervise/qmail-smtpd/run
    chmod 755 /var/qmail/supervise/qmail-smtpd/log/run

13. link supervise katalogene i /service:

    ln -s /var/qmail/supervise/qmail-send /var/qmail/supervise/qmail-smtpd /service

    qmail starter så etter kort tid. dersom du ikke vil ha qmail kjørende ennå:

    qmailctl stop

14. La localhost få sende via SMTP:

    echo '127.:allow,RELAYCLIENT=""' >>/etc/tcp.smtp
    qmailctl cdb

15. Filer som må/bør endres:
    • /etc/qmail/me (vanligvis navn som skal vises utad)
    • /etc/qmail/locals (f.eks localhost og gjeldene domene)
    • /etc/qmail/smtproutes (spesiell ruting av mail, sjekker ikke MX)
    • /etc/qmail/rcpthosts (domener som mottar mail her)
