Hi all, I've put up Dropbear 2013.57 as usual at https://matt.ucc.asn.au/dropbear/dropbear.html
As well as a few bug fixes it has significant improvements to the number of round trips required to set up a connection - useful for high latency links. Cheers, Matt 2013.57 - Monday 15 April 2013 - Decreased connection setup time particularly with high latency connections, the number of round trips has been reduced for both client and server. CPU time hasn't been changed. - Client will send an initial key exchange guess to save a round trip. Dropbear implements an extension [email protected] to allow the first packet guess to succeed in wider circumstances than the standard behaviour. When communicating with other implementations the standard behaviour is used. - Client side: when public key or password authentication with $DROPBEAR_PASSWORD is used an initial authentication request will be sent immediately rather than querying the list of available methods. This behaviour is enabled by CLI_IMMEDIATE_AUTH option (on by default), please let the Dropbear author know if it causes any interoperability problems. - Implement client escape characters ~. (terminate session) and ~^Z (background session) - Server will more reliably clean up utmp when connection is closed, reported by Mattias Walström - Don't crash if /dev/urandom isn't writable (RHEL5), thanks to Scott Case - Add "-y -y" client option to skip host key checking, thanks to Hans Harder - scp didn't work properly on systems using vfork(), thanks to Frank Van Uffelen - Added IUTF8 terminal mode support (Linux and Mac OS). Not standardised yet though probably will be soon - Some verbose DROPBEAR_TRACE output is now hidden unless $DROPBEAR_TRACE2 enviroment variable is set - Fix using asymmetric MAC algorithms (broke in ) - Renamed configure.in to configure.ac to quieten autoconf, from Mike Frysinger
