Setting ROOTPW not properly documented in fai-guide?
Hi, When trying to figure out hot to change the default rootpassword of installed clients by just changing the variable "ROOTPW" in a class .var file, I believe that the information in the fai-guide and comments in the configs is not helpful to get a new password. The only things I found that worked is * copying a password value from a real /etc/shadow file * using mkpasswd as written in http://www.mail-archive.com/linux-fai@uni-koeln.de/msg00210.html Both of these ways are not documented in the FAI-guide, and the hint on crypt or md5 in the guide/comments would lead me to use the crypt command (in the mcrypt package) or the md5sum command - both did not work for me. any experiences with this, or other ways how to do that?

Re: Setting ROOTPW not properly documented in fai-guide?
Hello!
I can confirm that it works at least under FAI 3.1.8 (etch). I prepare
my encrypted passwords from the plain text with
makepasswd --clearfrom $PLAINFILE --crypt-md5 --randomseed NNN | awk '{
print $2 }'
(NN is an integer)
and store them in a closely guarded file. During FAI installation one of
my .var scripts extracts the correct encrypted password from that file
and sets ROOTPW to the value.
The actual password setting occurs in scripts/FAIBASE/10-misc (from the
sample scripts which came with FAI) and the corresponding lines are
# set root password
echo "root:$ROOTPW" | $ROOTCMD chpasswd --encrypted
Maybe you have modified that script, or it is not run at all in your
setup?

No - you misunderstood me a little bit :) The question was not if/how it works with mkpasswd - I got this working as you write it - just with less security as it's less critical and without all those options for mkpasswd. The question is why using mkpasswd is not documented in the fai-guide, and if/how the things documented in the fai-guide (it says only "use crypt/md5") can be made to work. Henning
FAI on a thumper
Hi all we are currently trying FAI 3.3.3 on a thumper (Sun Fire x4500) but right now it does not like it too much: [...] Executing: parted -s /dev/sdy unit chs print free Executing: parted -s /dev/sdz unit TiB print Executing: parted -s /dev/sdz unit B print free Executing: parted -s /dev/sdz unit chs print free Executing: vgdisplay --units m -s Executing: mdadm --detail --scan --verbose -c partitions INTERNAL ERROR in setup-storage: Invalid device /dev/sdy1 Please report this error to the Debian Bug Tracking System. the device /dev/sdy is there (I can query it via smartctl) but sdy1 is not (yet) there. If I run against another disk, e.g. sdc all is fine, but this machine can only boot from very specific disks :( When enabling debugging the output get *very* lengthy, but I can try to capture it, if people would like to see it. Any ideas how I can proceed? Cheers Carsten
