openssh unix dev - Jun 2013 - PTY allocation?

I'm running a 5.0p1 derivative SSH server (that for various reasons I
can not upgrade), on a host system that does not support PTYs.

 

Attempts to connect to that sshd via sftp are failing due to an
inability to allocate a pty.   I can't really see a reason that an sftp
session requires a pty.   Is this addressed in later versions?   Should
I patch my system to avoid even trying to allocate a pty for an sftp
session?

 

Thanks

me either.

Requesting a tty is a function of the client, not the server.

maybe.  which client software are you using?  OpenSSH has the
RequestTTY option, but it looks like the default of "auto" doesn't
request one with sftp sessions.
