There is a gvfs-list (CCed).

At the moment the timeout is hardcoded in the sftp backend in
daemon/gvfsbackendsftp.c:

#define SFTP_READ_TIMEOUT 40   /* seconds */

It was recently
(http://git.gnome.org/browse/gvfs/commit/?id=a86f1a8fb7ecd5a8e3e22d7f95c4f022ba3e7211)
bumped from 20 to 40 seconds due to a similar request.

We have long wanted to add per-mountpoint config support, but this has
not happened yet, so its not possible to set this yourself.

What kind of timeout do you require?

Thank you for your reply. The timeout to ssh into the machine is just over 20 seconds :(. Which version of gvfs did this patch make it into? 

Also, what are the problems with adding support for per-mountpoint config support? i.e. would it require a major re-write or would it be relatively simple? From my understanding it would simply require adding support for a 'TimeOut' variable under '/usr/share/gvfs/mounts/sftp.mount' and then using this variable in the appropriate places in the code i.e. the two places in 'gvfsbackendsftp.c' in the link which you sent.

Thank you
