Hi Atsuhiko,
Jingran Xiao gave me a new jsch-0.1.43.jar which has the patch and also has the
zlib code in it. I loaded the source code from jsch-0.1.43.zip and made a
jsch-0.1.43.rc2.jar. Unfortunately both of the new versions hang at the same
place in the code:
Session session=jsch.getSession(user, host, port);
session.connect();
Channel channel=session.openChannel("sftp");
channel.connect(); --------------------------------------------debugging
has shown that the process hangs here
ChannelSftp c=(ChannelSftp)channel;
The host I tried to SFTP to is HP ProCurve switch. The ProCurve Network OS has
SSH server(including SFTP) but they do NOT have the SSH client.
Here is the version string of that remote sshd:
Connected to host.
Escape character is '^]'.
SSH-2.0-OpenSSH_3.7.1p2
Here is the SSH information of a ProCurve switch:
SSH Enabled : Yes Secure Copy Enabled : Yes
TCP Port Number : 22 Timeout (sec) : 120
Host Key Type : RSA Host Key Size : 2048
Ciphers : aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc,
[email protected],aes128-ctr,aes192-ctr,aes256-ctr
MACs : hmac-md5,hmac-sha1,hmac-sha1-96,hmac-md5-96
I can make a connection to the switch using FileZilla. Please let me know if I
can try some other approach.
Best regards,
Bin Jiang

Subject: Dose JSch SSH/SFTP follow to SSH RFCs
Hi Atsuhiko,
I have sent following questions to you via yahoo mail last Monday. I would
greatly appreciate it if you could give me your response as soon as possible.
On my current project, I use JSch library to support SSH/SFTP with HP ProCurve
switches. Our switch SSH supports all RFCs describing SSH in the followings.
Could you please let me know if JSch SSH/SFTP follows to these SSH RFCs?
* SSH Assigned Numbers (RFC
4250)<http://www.snailbook.com/docs/assigned-numbers.txt>
* SSH Protocol Architecture (RFC
4251)<http://www.snailbook.com/docs/architecture.txt>
* SSH Authentication Protocol (RFC
4252)<http://www.snailbook.com/docs/userauth.txt>
* SSH Transport Layer Protocol (RFC
4253)<http://www.snailbook.com/docs/transport.txt>
* SSH Connection Protocol (RFC
4254)<http://www.snailbook.com/docs/connection.txt>
I have got the same "java.io<http://java.io.IO>.IOException: channel is broken"
problem as Scott Halepaska had when I transmit files from ProCurve switches.

You mentioned in your exchanged mail that the version
jsch-0.1.43-rc2.zip<http://www.jcraft.com/jsch/jsch-0.1.43-rc2.zip> can correct
this problem. Where can I find this version
http://www.jcraft.com/jsch/jsch-0.1.43-rc2.zip?
Best regards,
Bin Jiang
