+- add dialog to ask for username
+- rename() causes SSH to die
+- How to handle overwrite?
+- After the user cancels with the stop button, we get ERR_CANNOT_LAUNCH_PROCESS
+  errors, until we kill the ioslave. Same thing after trying the wrong passwd
+  too many times.
+  This is happening because TDEProcess thinks that the ssh process is still running
+  even though it exited.
+- How to handle password and caching?
+  - Write our own askpass program using kde
+  - set env SSH_ASKPASS_PROGRAM before launching
+    -how to do this? TDEProcess doesn't give us access to env variables.
+  - Our askpass program can probably talk to the tdesu daemon to implement caching.
+- chmod() succeeds, but konqueror always puts permissions to 0 afterwards. The properties
+  dialog is right though.
+  Nevermind - ftp ioslave does this too! Maybe a bug with konqueror.
+- stat does not give us group and owner names, only numbers.  We could cache the uid/name and
+  gid/name so we can give names when doing a stat also.
+  
+7-13-2001 - ReadLink stopped working. sftp server always retuns a file not found error
+          - Need to implement 64 bit file lengths-->write DataStream << for u_int64
+            Still need to offer 32 bit size since this is what kde wants. ljf
+          - rename() isn't exactly causing ioslave to die.  The stat of the file we are
+            going to rename is killing the slave.  The slave dies in the statEntry() call.
+            I don't know what I am putting in the UDS entry that is causing this. ljf
+7-14-2001 - got put, mimetype working ljf
+          - fixed readlink problem - I was sending the wrong path. doh! ljf
+7-17-2001 - If the user changes the host, the slave doesn't change host! setHost() is not
+            called, nor is another ioslave spawned. I have not investigated the problem
+            yet. ljf
+7-21-2001 - got slave working with kde 2.2 cvs
+7-22-2001 - probable solution to getting password prompt -- open with controlling
+            but don't connect stdin/out to terminal. duh!
+8-9-2001  - Doh! I haven't kept very good logs. Look at the cvs logs for better info.
+          - At this point kio_sftp is using KSshProcess which I wrote in order to make
+            a standard interface to the various version of ssh out there. So far it is
+            working fairly well.  We also now report host key changes to the user and
+            allow them to choose whether or not to continue. This is a big improvement.
+          - Todo: support use of keys and ssh agent
+                  put()'s resume functionality needs some work
+1-26-2002 - Rewrote put() following the ftp::put() so it should behave the same way
+          - increase the size of the data packet we ask for in ::get up to 60k.
+            Through-put increases nicely.
+          - Call closeConnection() from construction. Keeps from having unused ssh
+            processes laying around after failed operations.
+2-19-2002 - get() now emits mimetype, fixes problem with konqi not downloading file for
+            viewing in kpart.
+          - get port number using getservbyname instead of hard coding it.
+2-27-2002 - testing before committing back to cvs, test with openssh 3, ssh 3
+6-?-2002 - rewrote openConnection() to using new KSshProcess connect proceedures
+7-20-2002 - Don't put up a message box when auth fails because of now or changed key,
+            the call to error() will put up the dialog.
+          - Connect fails and no more password are prompted for when we get
+            ERR_AUTH_FAILED from KSshProcess.
+9-15-2002 - stuff
+9-29-2002 - the last i18n string updates, fixed problem with uploading files to
+            openssh server.
+5-8-2003  - check whether operation types are supported by the negotiated sftp
+            protocol version

+DEBUGGING
+
+The best way to debug this slave is to send debug info to a
+file using 'kdebugDialog --fullmode'. Then you can 'tail -f' the file to 
+see debug messages in real-time.
+
+I also suggest getting the openssh source and recompiling sftp-server to 
+send messages to the auth log.  This can be done in sftp-server.c be defining
+DEBUG_SFTP_SERVER.
+
+You can do the same with the ssh client by finding the two calls to log_init() 
+in ssh.c and changing the last argument from 1 to 0 and recompiling.

+ * See the KSshProcess header for examples on use.
+ *
+ * This class uses a hacked version of the PTYProcess
+ * class.  This was needed because the tdelibs PTYProcess does not provide 
+ * access to the pty file descriptor which we need, because ssh prints the
+ * password prompt to the pty and reads the password from the pty.  I don't
+ * feel I know enough about ptys to confidently modify the orignial
+ * PTYProcess class.
+ *
+ * To start ssh we take the arguments the user gave us
+ * in the SshOptList and build the ssh command arguments based on the version
+ * of ssh we are using.  This command and its arguments are  passed to
+ * PTYProcess for execution.  Once ssh is started we scan each line of input
+ * from stdin, stderr, and the pty for recognizable strings.  The recognizable
+ * strings are taken from several string tables.  Each table contains a string
+ * for each specific version of ssh we support and a string for a generic
+ * version of OpenSSH and commercial SSH incase we don't recognized the 
+ * specific ssh version strings (as when a new SSH version is released after
+ * a release of KSshProcess).  There are tables for ssh version strings,
+ * password prompts, new host key errors, different host key errors,
+ * messages than indicate a successful connect, authentication errors, etc.
+ * If we find user interaction is necessary, for instance to provide a 
+ * password or passphrase, we return a err code to the user who can send
+ * a message to KSshProcess, using one of several methods, to correct
+ * the error.
+ *
+ * Determining when the ssh connection has successfully authenticationed has
+ * proved to be the most difficult challenge.  OpenSSH does not print a message
+ * on successful authentication, thus the only way to know is to send data
+ * and wait for a return.  The problem here is sometimes it can take a bit
+ * to establish the connection (for example, do to DNS lookups).  This means
+ * the user may be sitting there waiting for a connection that failed.
+ * Instead, ssh is always started with the verbose flag.  Then we look for
+ * a message that indicates auth succeeded.  This is hazardous because
+ * debug messages are more likely to change between OpenSSH releases.
+ * Thus, we could become incompatible with new OpenSSH releases.

+ *    passwordPrompt - pty

+ *    authSuccessMsg - stderr (OpenSSH), 
+ *    authFailedMsg - stderr
+ *    hostKeyMissing - stderr
+ *    hostKeyChanged - stderr
+ *    continuePrompt - stderr
+ * 
+ * We will use a select to wait for a line on each descriptor. Then get
+ * each line that available and take action based on it.  The type
+ * of messages we are looking for and the action we take on each
+ * message are:
+ *   passwordPrompt - Return false, set error to ERR_NEED_PASSWD.
+ *                    On the next call to connect() we expect a password
+ *                    to be available.
+ *                    
+ *   passpharsePrompt - Return false, set error to ERR_NEED_PASSPHRASE.
+ *                      On the next call to connect() we expect a
+ *                      passphrase to be available.
+ *   
+ *   authSuccessMsg - Return true, as we have successfully established a
+ *                    ssh connection.
+ *   
+ *   authFailedMsg - Return false, set error to ERR_AUTH_FAILED. We
+ *                   were unable to authenticate the connection given
+ *                   the available authentication information.
+ *   
+ *   hostKeyMissing - Return false, set error to ERR_NEW_HOST_KEY. Caller
+ *                    must call KSshProcess.acceptHostKey(bool) to accept
+ *                    or reject the key before calling connect() again.
+ *   
+ *   hostKeyChanged - Return false, set error to ERR_DIFF_HOST_KEY. Caller
+ *                    must call KSshProcess.acceptHostKey(bool) to accept
+ *                    or reject the key before calling connect() again.
+ *

+ * Provides version independent access to ssh. Currently supported
+ * versions of SSH are:
+ *   OpenSSH 2.9p1
+ *   OpenSSH 2.9p2
+ *   OpenSSH 3.0
+ *   OpenSSH 3.1
+ *   Commercial SSH 3.0.0
+ * Other versions of OpenSSH and commerical SSH will probably work also.
+ *
+ * To setup a SSH connection first create a list of options to use and tell
+ * KSshProcess about your options. Then start the ssh connection. Once the
+ * connection is setup use the  stdin, stdout, stderr, and pty file descriptors
+ * to communicate with ssh. For a detailed example of how to use, see
+ * ksshprocesstest.cpp.
