[Jsch-cvs] downloading concurrent files

[Vijaya N. <vi...@hp...>]

Hi,
Is there an example for concurrent file transfers using jsch library in 
the examples directory ?

In order to achieve concurrent file transfer, do I need to open two 
sessions, connect,
and open different channel from each sessions ?

The reason i am asking that question is If I just use one session and 
open two different channels
then i am not actually getting the same transfer rate.
somehow, the speed is split into half ? is it true ? or something wrong 
in my setup ?

One more question regarding the performance.
In one of the network setup, compression level "3" works great, the 
performance is matching up to globus-url-copy,
where as in another setup, setting up compression to any level is 
working very bad. Do you know what could be reason for that.

If any one could tell what are the key parameters needs to be set in 
order to speed up the performance.

Thanks a lot.
Viji

[Jsch-cvs] Using jsch in a batch process

[J.D. R. <jd...@gm...>]

Hi.  New guy here.

I've recently embarked on a (possibly foolish) mission to learn Java by
porting a suite of scripts from Perl, starting with one that does
non-interactive SFTP.  I'm not wholly unprepared for this journey, as I've
programmed in a variety of other languages, but the (ahem) limited
documentation of jsch has me somewhat stymied.

The general flow of my program goes like this:

* Establish connection using login information held in environment variables
(userid, hostname, password) [getting via java.util.Properties].
* Automatically accept host key (or not) based on boolean parameter.  Throw
exception if accept=false and key not known.
* Execute get or put for named file.
* Disconnect.

Simple, right?  Maybe.  It's not obvious to me from reading the examples
where the acceptance of the host key happens. I've hacked the session
connection enough that I think establishing the connection will work, but
I've got to get the whole session established (host key and all) before I
can test, as there's no interactivity.

Can anyone help?  Has anyone else here done something similar?  Code
snippets are appreciated.

thx

JD

[Jsch-cvs] invalid data when reconnecting using keyboard interactive authentication.

[Patrick O. H. <PH...@co...>]

I can connect a session using keyboard interactive authentication,
but if I disconnect and try to connect again (using the same session
object), I get "invalid data," thrown from Session.connect().
this does not happen if I use password authentication.

are there any workarounds for this?

Patrick
