Subject Jsch issue with compression algorithm
Date Mon, 20 Oct 2014 04:16:53 GMT
Hello All, 

I have been able to narrow down this issue to below - 

1) I enabled client to server compression configuration on Jsch  by setting compression=2
as an option on camel route.
2) With this, Jsch sets client to server compression configuration as -  JSCH -> kex: client:
zlib@openssh.com, zlib, none
3) When server is configured as below the sftp connection is successful
  JSCH -> kex: server: none,zlib@openssh.com
4) However, if the server is configured as any of the below the sftp connection is not successful
 JSCH -> kex: server: none,zlib
 JSCH -> kex: server: zlib

So if zlib@openssh.com is not configured on server, Jsch fails with the exception below

Caused by: com.jcraft.jsch.JSchException: Algorithm negotiation fail
        at com.jcraft.jsch.Session.receive_kexinit(Session.java:583) ~[ftu-server-3.0.3.jar:na]
        at com.jcraft.jsch.Session.connect(Session.java:320) ~[ftu-server-3.0.3.jar:na]
        at org.apache.camel.component.file.remote.SftpOperations.connect(SftpOperations.java:115)
~[ftu-server-3.0.3.jar:na]

Has someone encountered this? Any ideas to resolve this. Thanks in advance.

Regards
Keshav

Subject: RE: JSch connection issue with Maverick SSHD server


Hello 

I am using Camel routing library to set up sftp routes to a remote sftp server. Camel user
Jsch library (version 0.1.50) for all sftp operations and jsch-zlib (version 1.1.3) for the
compression. However I encounter the exception below with this set up. Could someone advise/point
to a resolution? Many thanks in advance.

Subject: RE: JSch connection issue with Maverick SSHD server

Hello 

JSch has configuration parameters to set compression algorithm for client to server and server
to client transport. 

compression.c2s
    Compression algorithms for client-to-server transport. The default is "none", but this
library also supports "zlib" and "zlib@openssh.com". (Other compression algorithms can't be
put in, it seems.)

compression.s2c
    Compression algorithms for server-to-client transport. The default is "none", but this
library also supports "zlib" and "zlib@openssh.com". (Other compression algorithms can't be
put in, it seems.)

Is it possible to set this configuration parameter in Options part of Camel URI? 

The only Option I could see on Camel's FTP2 page is below - compression | Default Value =
0 | SFTP Only: Camel 2.8.3/2.9: To use compression. Specify a level from 1 to 10. Important:
You must manually add the needed JSCH zlib JAR to the classpath for compression support.


Does setting this Camel option (with JSch zlib on classpath) automatically sets both these
configuration parameters.

Keshav

Thanks for your reply Nodet, 

The sftp server is hosted externally and is outside our infrastructure. I can't make any changes
to the server, and need to make client work with the server configuration.  Would you know
how I can do it, found the below on Camel's ftp2 page and guess need to look at this - 

compression | Default Value = 0 | SFTP Only: Camel 2.8.3/2.9: To use compression. Specify
a level from 1 to 10. Important: You must manually add the needed JSCH zlib JAR to the classpath

Your server is configured with "zlib" compression only, while the client only supports compression
"none", so there's a mismatch and both can't talk to each other.  You need to configure the
server with both "zlib" *and* "none" compression factories.
