[scponly] Re: Let users change their passwords?

[C.Schwabl at mobilkom.at]

Hello,

i have just played around with this topic and i think i found a solution for
non-chrooted
environments.

I changed the source so that the command passwd is a vailid command.

With this, users can change their passwords using a command like this:

ssh -t <user>@<hostname> passwd
passwd: Changing password for <user>
Enter login password: <old password>
New password: <...>
Re-enter new passwort: <...>
passwd (SYSTEM): passwd successfully changed for <user>
Connection to <hostname> closed.

Windows users can use a tool like plink (cmd-line ssh from putty 
http://www.chiark.greenend.org.uk/~sgtatham/putty/) to change their pwd.

Any commends on this?

Still searching for a solution on using this with a chrooted-environment.
Some mechanism to sync the password file in the chrooted /etc/passwd to the 
global /etc/passwd (or shadow)?

Would like to hear some opinions on this..

greetings, 
Schwabl Christian

btw: scponly is a great tool. keep on the good work...
