Hi Keshav, Looking at SftpOperations.java[1] it is obvious that both these configuration parameters are set automatically when defining a compression level above 0.

RE: JSch connection issue with Maverick SSHD server
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 for compression support. Regards Keshav -Original Message- From: Guillaume Nodet [mailto:gno...@apache.org] Sent: Monday, September 15, 2014 2:15 PM To: users@camel.apache.org Subject: Re: JSch connection issue with Maverick SSHD server 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. 2014-09-15 7:39 GMT+02:00 Baweja, Keshav keshav.baw...@jpmorgan.com.invalid : Hello I am using Camel 2.13.2 in my application to build up routes to download files from sftp server locations.
