Subject RE: Jsch issue with compression algorithm
Date Mon, 20 Oct 2014 06:38:41 GMT
Hi, 

I just check the configuration, “none” means the compression will not be done if sshd
doesn’t support to compress the data from sshd to jsch. 

Current release has supported following properties,
* compression.s2c: zlib, none
  default: none
  Specifies whether to use compression for the data stream
  from sshd to jsch.  If "zlib,none" is given and the remote sshd does
  not allow the packet compression, compression will not be done.

Did you try to set the compression option to 0 ?
BTW, you can change the code to see if it works any way :)
