after spending a couple of hours debugging my brother-in-law’s crashing computer (& in german, just to make it easier), I ran into this site http://www.dumpanalysis.org/ which is so good I might just have to buy a few of the books listed on it.

first up, kick off an EC2 ubuntu/hardy instance, ssh in as usual

apt-get install openafs-fileserver
# set cell name to muse.net.nz
# set cache size to 10Gb
# set cellDB to afsdb.muse.net.nz
# update /etc/openafs/CellServDB
>muse.net.nz #home
121.73.27.12 #afsdb.muse.net.nz
rm /etc/openafs/server/CellServDB; ln -s /etc/openafs/CellServDB /etc/openafs/server/CellServDB
# sweet!

three changes required -

  • configure sendmail to use a remote host for all mail in /etc/mail/submit.cf
    # changes to fwd mail directly to smart host
    #D{MTAHost}[127.0.0.1]
    D{MTAHost}[smtp.muse.net.nz]
  • configure local aliases mapping to remap users to a destination address in /etc/mail/aliases
    # Well-known aliases — these should be filled in!
    # root:
    root: root@muse.net.nz
  • permit relaying on smart host (postfix in my case) in /etc/postfix/main.cf
    mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, akai.$mydomain
