Subject Ubuntu 18.04.1 + Docker -> Installed version of FreeRDP lacks support for the preconnection PDU
Date Mon, 01 Oct 2018 18:37:05 GMT
Hello,

I installed a new virtual machine, docker, docker-compose, configured the
system – I am referencing guacamole/guacd and guacamole/guacamole from my
docker-compose.yml.

 

Connections to Hyper-V VMs are disconnected immediately (didn´t test
anything else). 

Docker logs guacd reveals the following:

 

guacd[86]: INFO:        Security mode: NLA

guacd[86]: WARNING:     Installed version of FreeRDP lacks support for the
preconnection PDU. The specified preconnection BLOB and/or ID will be
ignored.

Error: protocol security negotiation failure

guacd[1]: INFO: Connection "$fbccda9f-4170-4a4c-87ab-e824d1ae8434" removed.

 

docker exec -it guacd xfreerdp --version

This is FreeRDP version 1.0.2

 

Is this a known issue? How can I check the freerdp library version? Can I
upgrade the container? What else can I do?

Thanks & Best Regards, Joachim
