Re: Problem guacd timed out.

[Anburaj Palraj]

Hi Jorge ,

you are saying "soon after giving the timeout error if I click on
reconnect, the connection will normally no problem"

i would suggest you to capture the packets using tcpdump command for both
the cases from Ubuntu server and analyse , then you will get to know where
it is failing  .

tcpdump -nX -s0 -i any host XX.XXX.XX.XX and port 22/3389 .

if you want to save and analyse in wireshark , use the below command

tcpdump -nX -s0 -i any host XX.XXX.XX.XX and port 22/3389 -w /tmp/1.pcap


also you to can do  continues check (telnet or check_tcp ) the port (22 or
3389) from this guacamole machine .

i hope this will help you  .

 Hi,

 I made a new install of Ubuntu 16.04.1 LTS and Guacamole
 0.9.11-incubating released on February 3rd.

 Since the last version, I have occasionally had trouble connecting to
 some servers at random.

 An example is as we can see below. I clicked to connect to a server and
 it stays in this screen:


 [image: Imagem inline 1]

 After a while this screen appears:

 [image: Imagem inline 2]


 If I click on "reconnect" the connection will go normally. But if I
 wait a few minutes and try to reconnect to the same server, the same
 problems happen again.

 Below is the output of the guacd log in debug mode and tomcat8.

 I'm just using tomcat8, with mysql. Apache or nginx is not installed.

Re: Problem guacd timed out.

[Jorge Camara]

We have no proxy on the network. And the antivirus on my machine is turned
off.
And as I said, soon after giving the timeout error if I click on reconnect,
the connection will normally no problem.

It is a fresh installation of the ubuntu server on Virtual Machine and
guacamole. All servers are all from the same network as well.

I also tried to use the browser in anonymous mode but it has the same
effect. Linux server also has no active firewall.

Maybe some parameter on the linux server I've gone unnoticed, or something
else.

My intention to use Guacamole is only to record the remote connections for
audit purposes.

If you have something else that I can clarify please let me know.

Thanks

Re: Problem guacd timed out.

[Mike Jumper]

As both guacd and the web application are reporting that the other is not
responding, the most likely explanation from my experience would be:

1) There is something on the network between the browser and the Guacamole
server which is eating/buffering the data stream (such as a proxy or
certain virus scanning software)
2) guacd is waiting for a response from the client before sending further
data
3) With the client waiting for guacd, and guacd waiting for the client,
both timeout at the same time.

Do you know if there might be a proxy between the browser in question and
the Guacamole server?

Problem guacd timed out.

[Jorge Camara]

Hi,

I made a new install of Ubuntu 16.04.1 LTS and Guacamole 0.9.11-incubating
released on February 3rd.

Since the last version, I have occasionally had trouble connecting to some
servers at random.

An example is as we can see below. I clicked to connect to a server and it
stays in this screen:


[image: Imagem inline 1]

After a while this screen appears:

[image: Imagem inline 2]


If I click on "reconnect" the connection will go normally. But if I wait a
few minutes and try to reconnect to the same server, the same problems
happen again.

Below is the output of the guacd log in debug mode and tomcat8.

I'm just using tomcat8, with mysql. Apache or nginx is not installed.
