Hello, I'm not so sure...
From RFC4251 http://tools.ietf.org/html/rfc4251 : "The Transport Layer Protocol [SSH-TRANS] provides server authentication, confidentiality, and integrity. It may optionally also provide compression. The transport layer will typically be run over a TCP/IP connection, but might also be used on top of any other reliable data stream." From RFC4253 http://tools.ietf.org/html/rfc4253#section-6.2 : "The following compression methods are currently defined: none REQUIRED no compression zlib OPTIONAL ZLIB (LZ77) compression " So now I am even quite sure of the opposite... The reason for this topic was some lecture about lbxproxy (R.I.P.), and the conclusion of the developer: "The only useful changes to the wire protocol are the use of lossless image compression within X or a full wire-level compression proxy such as SSH underneath X." I think we'll try to compess the traffic. If we'll have some results, we will send them for the discussion Greetings, Wojtek Rob Owens schrieb: > On Wed, Feb 04, 2009 at 06:29:35PM +0100, Wojtek Polcwiartek wrote: >> Hallo, >> >> We watched the 'ps' output on the client and saw that the 'ssh'-process >> starts without '-C' switch.
