The problem reproduces on my system. I'll have a look when I can.

[John]

hi there, did you get a chance to fix the issue.

[Shachar Shemesh]

I'm sorry. I've been very busy lately.
Atypically for sshpass, the problem is a logic problem, not a system problem. I think the state machine doesn't realize that the password prompt has been satisfied, and doesn't move on to the part where it acts as a passthrough.

[John]

No worries, take your time I am in no rush, fix it whenever you can.

Snippet from sudo's strace

ioctl(10, TIOCGPTPEER, 0x102)    = 11
dup3(11, 0, 0)                   = 0
dup3(11, 1, 0)                   = 1
dup3(11, 2, 0)                   = 2

Essentially, it opens its own controlling TTY, and then sets that as the standard output, error and input for the process. This is the reason it doesn't print to the terminal: it's printing to sshpass.

We can, perhaps, set sshpass to forward the output, but that won't work completely either. In order to work, we need to also redirect the input, and I'm not sure it makes sense to do that.

i am not sure about it. you can fix it the way you like. i have no idea am the end user.
