Description Ronny Buchmann 2004-04-23 04:50:38 EDT
Description of problem:

"scp userx@host1:file usery@host2:" doesn't prompt for password of
usery@host2 and fails


Version-Release number of selected component (if applicable):
3.6.1.p2-19

How reproducible:
always

Additiional Info:
A password is only read from /dev/tty, but when running scp (or ssh
with a 
command), you don't get a tty.

in sshconnect2.c:
userauth_passwd()
...
         password = read_passphrase(prompt, 0);


One can try:

ssh -t -x userx@host1 "ssh usery@host2"

wich actually works (as it forces tty allocation), without -t you get
the same 
error, as when doing remote to remote scp.

So to scp between remote hosts, you need to:

ssh -t -x userx@host1 "scp file usery@host2"

fix for scp

I think this fixes scp, but I did not test it yet.

second attempt

this one actually works, but I don't know if the removal of -n has any security
implications. I hope someone can comment on this.
