SFTP not working in the background
I'm modifying some code to SFTP files because the remote servername and user are changing. The keys have been correctly installed and I'm using the -B option to automate the actions following connection e.g. cd, put etc. This is all working nicely. However, when I wrap this up to call it from a daemon process, it hangs! Investigation seems to show that I'm getting a SIGTTOU message and the sftp process stops. The process seems to work fine to the old server - both old and new sftp servers are windows based!
Are there any SFTP server configurations that define whether the client must run interactively or daemonised?
If the server can't be changed, what options do I have at the client end? Do I catch the SIGTTOU and ignore it?

Well just rechecked connectivity to the old server which used to work but doesn't any longer, so looks like it may be a client side issue!

gesftpserver

gesftpserver(8) 					      System Manager's Manual						   gesftpserver(8)

NAME

       gesftpserver - Green End SFTP Server

SYNOPSIS

       /usr/lib/gesftpserver [OPTIONS]

DESCRIPTION

       gesftpserver implements the SFTP protocol.  It is normally run as an SSH subsystem but can be run in other contexts if necessary.

CONFIGURING OPENSSH

       By  default,  OpenSSH  will  use its native SFTP server in response to requests for the SFTP subsystem.	To use gesftpserver instead, add a
       suitable Subsystem command to sshd_config (and remove the existing one if present).  For example:

       Subsystem  sftp /usr/lib/gesftpserver

IMPLEMENTATION DETAILS

       gesftpserver supports up to version 6 of the SFTP protocol and the following extensions:

       newline
	      Reports the server's newline convention to the client.

       space-available
	      Equivalent to df(1).

       supported
	      v5 capability details

       supported2
	      v6 capability details

       text-seek
	      Used for resuming text file downloads.

       vendor-id
	      Reports server name and version to client.  gesftpserver reports a vendor of "Green End" and  a  server  name  of  "Green  End  SFTP
	      Server".

       versions
	      Lists available versions.

       version-select
	      Select version.

       posix-rename@openssh.org
	      Provides POSIX rename semantics even in pre-v5 SFTP.
