How about this ? ( tested on my debian 3.0 and FreeBSD 4.6 with 5 test
accounts )
on linux box
$pwunconf
$cp /etc/passwd /root/passwd.conv
$awk -F":" '{print $1":"$2":"$3":"$4":put login class here:put pass change
time
here:put pass expire time here:"$5":"$6":"7}' /root/passwd.conv >
/root/passwd.bsd
$scp /root/passwd.bsd user@freebsd:~/
on freebsd box
$vipw
for within vipw , go to last line
:r! cat ~/user/passwd.fbsd
save
test , done
let me know if it worked ( it did for me )
NOTE: dont forget to delete the passwd.conf and passwd.fbsd files and to run
pwconv on the linux box .
