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!

I am not very familiar with the use of FTP, and trying to run it I found out that standard "ftp" is not working" but "sftp" is.
If sftp is allowed will that block ftp ? and if so where is this set ?
I thought there is no relationship, is that right ?
If so look here:
