[Ssh-sftp-perl-users] How to detect a "closed" connection ?

[hugues <Hug...@af...>]

Hi,

I'm using Net::SSH::Perl, and i'm having trouble finding the right way
to test if a connection (i.e, a Net::SSH::Perl object) is still
'connected'.

I'm working on an application than handles delivery to remote sites
with "long-life connection handles" through which it send data when
there is.

The application keeps the connection objects open and sends data when
available.

The problem is that the remote server may close its end of the
connection, and i need a way to detect that so i can re-establish
connection when that happens.

What i'm actually trying to do if  the following:

- try the operation (e.g 'put file') when i must
- if the operation fails, then check connection state, and reconnect
  if the check tells me that the connection is closed/broken.

I first thought i could use the Net::SSH::Perl::sock(), but that does
not seems to work, as it still returns me a valid socket object even
when the connection has been broken.

I tried to invoke the fileno() method on the returned socket, but that 
also works (returns me a valid file number instead of 'undef').

Any help would be greatly appreciated.

PS: I can provide more details if needed.
