To change the password on your Subversion/Trac account you simply connect to the server using SSH (as user passwd with password passwd). Example:
$ ssh -l passwd crux.nu <Type "passwd" as password>
You will be asked for your username and old password, then asked to type your new password twice. When you are done the server will automatically disconnect. Example:
+------------------------------------------------------+ | | | | | Change password for CRUX Subversion/Trac account | | | | | +------------------------------------------------------+ Enter username: foobar Enter old password: Enter new password: Re-enter new password: Updating password for user foobar Connection to crux.nu closed.
