Hi,
I've written a complex them to handle systemimager imaging process.
Everythings works perfectly and I can even image a system and finish boot
without rebooting.
I'm now in the process og having deployemnt onver an ssh tunnel.
My dracut module is able to handle local ssh keys, retreive a public key using
curl or rsync, but a more simple way would be to ask for ssh password.
I'm testing on CentOS-7 latest update.
My theme (script) works fin asking for a password, but I'm totally unable to
retreive it or use it.
I've tried 3 aproaches.
1/ without using the --command => unable to retreive the password from standard
input.
SSHPASS="$(plymouth ask-for-password --prompt 'Please, enter password:')"
sshpass -e ssh oscar-server 'hostname' > /tmp/result
=> Doesn't work. $SSHPASS is empty.
plymouth ask-for-password --prompt 'Please, enter password:' > /tmp/password
=> creates an empty password.
2/ using the --command => I must type the password twice???!!!
plymouth ask-for-password --prompt "Please, enter password:" --command "ssh
my-server 'hostname'" --number-of-tries=3 > /tmp/result
=> 1st time I tiype password: the password dialog close when I hit enter. Then
I type blindly and it works :-/
In text mode, I see the plymouth password prompt, I type the password, hit
enter and then I get the ssh password propt, I reenter password and it works.
3/ using systemd-ask-password => doesn't display password dialog under plymouth
and not available on centos-6...
SSHPASS="$(systemd-ask-password 'SSH password')" sshpass -e ssh oscar-server
'hostname' > /tmp/result
=> Works in text mode. In GUI mode, no password dialog appears.
=> Not available on centos-6 (that I have to support as it's still maintained).
Any advise or help would be greatly apreciated.
