Michael Jumper commented on GUACAMOLE-407: ------------------------------------------ Being able to specify {{debian:stable}} as a base image is also a plus. > Update guacd Docker image to build against more recent dependencies > ------------------------------------------------------------------- > > Key: GUACAMOLE-407 > URL: https://issues.apache.org/jira/browse/GUACAMOLE-407 > Project: Guacamole > Issue Type: Improvement > Components: guacd-docker > Reporter: Sven Gottwald > Assignee: Michael Jumper > Priority: Trivial > > The version of libssh2 within CentOS 7 lacks support for the more-recent > versions of SSH key exchange methods and MACs. As the [guacamole/guacd Docker > image|https://hub.docker.com/r/guacamole/guacd/] uses CentOS 7, it also lacks > this support. > Currently, the following key exchange methods are supported: > * diffie-hellman-group14-sha1 > * diffie-hellman-group-exchange-sha1 > * diffie-hellman-group1-sha1 > and the following MACs are supported: > * hmac-sha1,hmac-sha1-96 > * hmac-md5,hmac-md5-96 > * hmac-ripemd160 > * hmac-ripemd...@openssh.com > More recent libssh2 includes support for SHA2 and curve25519.
