root password does not work

[jfoucry]

Hello,

It MUST be me, but, the default root password seems to not work on https://mfsbsd.vx.sk/files/images/12/amd64/mfsbsd-se-12.1-RELEASE-amd64.img image.

I check with a friend who cannot connect to my machine too.

Password for root@mfsbsd:
Password for root@mfsbsd:
Password for root@mfsbsd:
root@xxx.xxx.xxx.xxx: Permission denied (publickey,keyboard-interactive).

Thank you for the notice! I have replaced all 12.1 images.

@mmatuska I was just about to click submit on a long bug report on this :) Good to see that it was already addressed. The issue was that no root password was set at all (empty), therefore ssh login didn't work.

I'll just leave this little script that I used to poke into various images while I was looking into the issue here, maybe it'll be useful for someone else in the future:

#!/bin/sh

set -e

MDUNIT="md11"
mdconfig -l -u ${MDUNIT} && /usr/bin/false
MDDEV="/dev/${MDUNIT}"
TEMPDIR=/tmp/mfsbsd$$
mkdir -p ${TEMPDIR}/mnt

for file in "$@"; do
  stat -f "%N (%Sm):" "${file}"
  mdconfig -f "${file}" -u ${MDUNIT}
  if echo ${file} | grep -Eq "\.iso\$"; then
    fstype="cd9660"
    device="${MDDEV}"
  else
    fstype="ufs"
    device="${MDDEV}p2"
  fi
  mount -t ${fstype} ${device} ${TEMPDIR}/mnt
  zcat ${TEMPDIR}/mnt/mfsroot.gz >${TEMPDIR}/mfsroot
  umount -f ${device}
  mdconfig -du ${MDUNIT}

  mdconfig -f ${TEMPDIR}/mfsroot -u ${MDUNIT}
  mount ${MDDEV} ${TEMPDIR}/mnt
  if [ -e ${TEMPDIR}/mnt/root.txz ]; then
    tar -xOf ${TEMPDIR}/mnt/root.txz rw/etc/master.passwd | egrep "^root"
  else
    egrep "^root" ${TEMPDIR}/mnt/etc/master.passwd
  fi
  umount -f ${MDDEV}
  mdconfig -du ${MDDEV}
  rm ${TEMPDIR}/mfsroot
done
rmdir ${TEMPDIR}/mnt
rmdir ${TEMPDIR}

Usage:

# ./check_mfsbsd_root_password.sh mfsbsd*.i??

@grembo thank you for the script! I would go one step further as Cirrus CI supports FreeBSD 12 VMs we can test the whole build process online.

Thanks for your job and your fast answer.
