Re: anyone still using fail2ban

[Mark Barber]

thanks mate but i came across that one somewhere, unfortunately it's not 
working for me on ubuntu server 16.04, tomcat 9.07, guacamole 9.14 java 10..
just wish the syntax itself wasn't so obscure.

to cover guacamole?
using it to protect a webmin instance but the default gucamole filter doesn't 
work and all the documentation i can find regarding syntax for filters is out 
of date.
Any hints please?

Re: State of Audio Input ?

[Mark Barber]

I used to use something similar that was for home editions of windows which do 
not have RDP funtionality.It is worth noting that page states "at reduced 
functionality" so may not actually support audio.

Well, that's aninteresting...project :-).

I don't know of a reason why Guacamole's audio input would not work
with that - at least, no reason related to Guacamole itself. Has audio
input been tried with another RDP client - either Microsoft or
Xfreerdp, against this same host, and is proved to work correctly?
Also, have you tested Audio Input from your Guacamole instance against
a host _not_ using RDPWrap to make sure that it works that way, as
well?

Re: Can't connect with the Guacamole

[Mark Barber]

Not examined the container myself but the most likely answer is the deployed 
file does not have the correct permissions from being deployed separately, they 
need to be the same  or close enough to the acct the guac instance is running 
under

I have checked again and it is listening on 0.0.0.0:4822
now I have successfully put the guacd.conf (Thanks by the way. adding double 
space helped for some reason) with the bind_host as 127.0.0.1, yet the 
container is still listening on 0.0.0.0:4822.

Now I still receive the "Connection refused". Is there anything I can try?

(Thanks for all your help)

Make sure guacd is running and listening on the expected address.

If it is running, check whether your Linux distro defines both "::1" and 
"127.0.0.1" for localhost, as that would cause TCP connections to 
localhost to round-robin between IPv6 and IPv4, whereas guacd will only 
listen on either IPv4 _or_ IPv6.
