There are two related issues here, both of which prevent connecting to Microsoft's Azure SFTP server, and presumably others which are strict to the RFCs. The client version string as listed above, and using a single LF vs. CR+LF after it. Fixing these two issues allows connection to Azure. Both changes are in Session.java. Line 71: private byte[] V_C=Util.str2byte("SSH-2.0-JSCH-"+JSch.VERSION); // client version needs to change to: private byte[] V_C=Util.str2byte("SSH-2.0-JSCH_"+JSch.VERSION); //...

I know this is old, but it appears that you are using CoZ:SFTP on the z/OS side. Can you try specifying the remote file as: /-/!DTS4.UP.G5TB.S60301 This is one of the documented formats for specifying z/OS file names in the CoZ:SFTP documentation.

This looks very much like a threading issue since the reproduction is so unpredictable. For a while, I thought this was caused by our own app threads, or a failure of the library to protect itself from being used in a multithreaded context. But, as my test case evolved, it became apparent that it was not our use of threads causing the problem. I synchronized all the JSch calls so that only a single one of our threads can use the lib at a time, and it still reproduced. Since app threads are reduced...

Why do you see that as a problem? Theis method's purpose is to send an absolute path. So it's checked if the given path is absolute and if not, the working directory is added in front. That's exactly what's happening with your example, so the path being sent to the server is e.g. /home/myuser/../../../etc/password. There are completely valid reasons why you want to send a path like this to a server, it's the server's obligation to restrict access to /etc/password no matter how the path is received...

I have retried the very same opration with wagon-ssh-external which uses ssh(1). No hang here. So must be an issue with JSch.

This new code has been introduced in WAGON-537. The fundamental difference is that the previous code request to stream the only remaining amount of bytes and the new one the at most the amount of bytes available to the buffer which is more than 916,

One particular command kills processes, but this intermittently fails, just does nothing, not even an exception. public static Session getSession(String ipAddressOfLinuxBox) { try { JSch jsch = new JSch(); Session session = jsch.getSession("root", ipaddress, 22); session. setPassword("blahblah"); session.setConfig("StrictHostKeyChecking"; "no"); } catch (JSchException je) {throw je;} } public static List executeExecCommand(String...

It's been a while since I wrote my fix, so the details are a bit vague. But I wrote a unit test that fails on 0.1.54 with the error in question, and succeeds on 0.1.55. So I think the 0.1.55 release does actually fix this issue. I'm a little bit disappointed that the JSch team did not contact me, or mention me. Oh well, that's life I suppose :)

The release notes of jsch-0.1.55 which was released 3 days ago among other says: -bugfix: fixed 'Invalid encoding for signature' errors in ssh-dss. I 'm wondering if this fixes also this issue....
