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 "z...@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 "z...@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.
Regards
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 for compression support.

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.
