Parse password file and populate variables


#!/bin/bash

#ypcat passwd > /tmp/passwd
cp /etc/passwd /tmp/passwd

while IFS=: read -r user pass uid gid gecos home shell
do
  echo "ipa-moduser -a -s \"$shell\" -c \"$gecos\" -d \"$home\" $user"
done < /tmp/passwd

exit 0


Another approach...


#!/bin/sh
# 1 is the nis domain, 2 is the nis master server
ypcat -d $1 -h $2 group > /dev/shm/nis-map.group 2>&1
IFS=$'\n'
for line in $(cat /dev/shm/nis-map.group); do
  IFS=' '
  groupname=$(echo $line|cut -f1 -d:)
  # Not collecting encrypted password because we need cleartext password to create kerberos key
  gid=$(echo $line|cut -f3 -d:)
  members=$(echo $line|cut -f4 -d:)
  # Now create this entry
  ipa group-add $groupname --desc=NIS_GROUP_$groupname --gid=$gid
  if [ -n "$members" ]; then
    ipa group-add-member $groupname --users=$members
  fi
  ipa group-show $groupname
done

P2V using dd for KVM-QEMU guest

Preface: I have certainly not exhaustively tested this process.  I had a specific need and found a specific solution that worked. Situation:  I was issued a shiny new laptop running Red Hat Enterprise Linux 7 (with Corp VPN, certs, Authentication configuration, etc...)  The image was great, but I needed more flexibility on my bare metal.  So, my goal was to P2V the corporate image so I could just run it as a VM. * Remove corporate drive and install new SSD * install corp drive in external USB-3 case * Install RHEL 7 on new SSD * dd old drive to a disk-image file in a temp location which will be an image which is the same size as your actual drive (unless you have enough space in your destination to contain a temp and converted image) * convert the raw disk-image to a qcow file while pushing it to the final location - this step should reduce the disk size - however, I believe it will only reduce/collapse zero-byte blocks (not just free space - i.e. if you de...

Sun USS 7100 foo

TIP: put ALL of your LUNs into a designated TARGET and INITIATOR group when you create them.  If you leave them in the "default" group, then everything that does an discovery against the array will find them :-( I'm struggling to recognize a reason that a default should even be present on the array. Also - who, exactly, is Sun trying to kid.  The USS is simply a box.. running Solaris .. with IPMP and ZFS.  Great.  If you have ever attempted to "break-in" or "p0wn" your IBM HMC, you know that there are people out there that can harden a box - then.. there's Sun.  After a recent meltdown at the office I had to get quite intimate with my USS 7110 and learned quite a bit.  Namely: there's a shell ;-) My current irritation is how they attempt to "warn you" away from using the shell (my coverage expired a long time ago to worry about that) and then how they try to hide things, poorly. I was curious as to what version of SunOS it ...

"Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1)"

"Error getting authority: Error initializing authority: Could not connect: No such file or directory (g-io-error-quark, 1)" One issue that may cause this to arise is if you managed to break your /etc/fstab We had an engineer add a line with the intended options of "nfsvers=3" but instead added "-onfsvers=3" and it broke the system fairly catastrophically.
