Thanks,

I will do the setup of Nginx .but I am not too much aware of Nginx so kindly 
help me to configured the Nginx to access the guacamole on web through https.

Re: HTTPS support for Guacamole

[Manoj Patil]

Thanks Nick.

I have one another doubt is when I am using a nginx that time I am stop the 
tomcat which is installed automatically when installed guacamole.

I have install the setup guacamole 1.0+tomcat 8 +xrdp in one machine and this 
machine is accessible over WAN . But in a day a “Unstable network “ message is 
flash and disconnect a connection .

This setup is accessible at client side  and those network are  good but in 
client side have 10 machines and the “unstable network message “ is not flash 
all the machine it flash randomly in machines.  

I am test same setup of new server at my side for  another client which is 
another  state those have also  issue.

From 2 days  I do a one of  setup Xrdp+centos 7 + tomcat 8 , this setup I am 
accessible through MSTSC web  HTML page at same client side and there is no 
issue of disconnect the server in whole day. From last 2 days this running fine 
.

So I request you what happen when I am going through the  this setup  guacamole 
1.0+tomcat 8 +xrdp and message is flash “Unstable network”

Please guide us

HTTPS support for Guacamole

[Manoj Patil]

Dear,

We implement the Guacamole with XRDP on centos 7.5 with HTTPS please confirm 
the guacamole run over tomcat with  https smoothly .

In my case I not used NGINX i am use  tomcat with HTTPS certificate. But I see 
I saw a “network connection is unstable message” in my WAN environment so I 
request to guide us 

If there any lack of network issue is occur .

Re: Required help for reducing High Bandwidth Utilization of Guacamole

[Manoj Patil]

ivanmarcus,

Thanks for cooperation .

Xrdp observation--

As per observation and experience i think the measure issue at Xrdp side .
Xrdp send the images in bitmap and jpeg compression but i could not see the
compression is done or not.

second thing is when you move the mouse pointer on RDp session then it also
send the bytes .

third one is , its calculate the RDP desktop in BPP,Width and Hight and
show  this bitmap to client . (rendering)

TLS 1.2 calls is default implemented in and it send request(read write) in
100 ms .

At Guacamole Side---

When Browser to Guacamole in idle no send receive .

But when connect to RDP session its continuously checking keepalive then
some bytes to be increased .

When at client side latency is 400-500 guacamole disconnected frequently .

 can you help in this to increased the parameter for checking the
connection to keepalive and checking latency.

Re: Required help for reducing High Bandwidth Utilization of Guacamole

[Manoj Patil]

Dear,

When i am connecting through MSRD client to xrdp --

In idle mode Bandwidth utilization is low ,but when i move mouse pointer
over windows and run my application bandwidth is utilized high.

In reverse i am connect MSRD client to MSRD (windows) host  in idle
condition bandwidth is low , when i am move mouse pointer over windows or
run application on windows host the utilization of bandwidth is very low.

When connect to FreeRDP client-> xrdp ,bandwidth utilization is also High
in idle condition.  In running condition using freerdp client utilization
is High.

Re: Required help for reducing High Bandwidth Utilization of Guacamole

[Manoj Patil]

Dear ivanmarcus,

To be specific. You say MSRDWC uses a lot less bandwidth than Guacamole,
however (if I understand correctly) from what you say you're using
Guacamole with a Xrdp client machine, and MSRDWC with a MSRD client
machine. I suggest you should first test with Guacamole to the MSRD client,
and then MSRDWC to the *same* client with the *same* parameters and the
*same* series of tests. IOW the *only* change in the lineup is MSRDWC vs
Guacamole - NOT the client machine as

I am done the setup of MSRDC at my place and measuring the sam scenario
Guacamole to xrdp client 

When connecting through browser to guacamole it's low bandwidth . when
connect guacad to xrdp host its huge bandwidth.

Guacamole to MSRDC client--

We test this setup with guacamole to MSRDC host through client there is
also a bandwidth utilization . we measure theough wireshark

MSRDC to same client --

When i am connected to  MSRDC with same parameter of bpp, width , height
etc and measure through wireshark there is tremendous different , its take
very low bandwidth .

When I am in idle mode in guacamole to xrdp its continuously check
keepalive and bandwidth utilizated that time.

When i am in idle in MSRDC there is no keepalive checking see in wireshark
hence bandits is very low .

Re: Required help for reducing High Bandwidth Utilization of Guacamole

[Manoj Patil]

Dear

I know the discussion is going on .., but still we try to minimised the
bandwidth utilization. I see in xrdp code there is a bitmap and jpeg cache
and compression with respectively bpp(bit per pixel), width and height .
but guacamole can done the compression and cache the bitmap and jpeg.

We see in guacamole they used ping and webp so I think the cache and
compression is mismatch.

Please if it correct?

The MSRDP setup is done at my end for testing purpose with same user ,same

What tool u used for measuring bandwidth.

Is there any resolution?

As per your snanshot RDP take to much bandwidth utilization . if u also 600
active connwction then the bandwidth utilization is around 40- 45 mbps.

Re: Required help for reducing High Bandwidth Utilization of Guacamole

[Manoj Patil]

Dear,

Thank For your appreciation .

The only thing that I noticed is that there is no compression between the
server and the client.
Meaning that full sized base64 encoded PNG images are send to the client,
which causes a high network load.

i am try to find out why more bandwidth is required for 600 connection and
how to reduced it.

My Observation is---

we observe that in my colleague company those people used  Microsoft remote
desktop Web client (using activex) for 1200 connection in 10 Mbps for huge
transaction. and

we used Xrdp+wine+Guacamole with 600 connection with 50 Mbps bandwidth .

what protocol they are used  ( Microsoft remote desktop Web client ) is
taking less bandwidth compare  with  Guacamole.

if we tune guacamole like that  Microsoft remote desktop Web client it is
valuable for all in low bandwidth.

without your help we can not do any changes in guacamole server.

Please guide.

Re: Required help for reducing High Bandwidth Utilization of Guacamole

[Manoj Patil]

Dear Mike,

Today we have measured bandwidth utilization using another verified tool on
our server and had below observations :

1. It seems that whenever *single *user session is in idle mode (No screen
change) , the bandwidth utilization is almost 707 B/s (which is low)

2. And whenever *single * session is active(means Screen changes with user
inputs) ,  the bandwidth utilization is almost 30-40 KB/s which is too high
for us for single  user session.

>From these observations, We might say that whenever screen changes on
remote session, frames for whole screen are transferred every time over n/w
and hence causes high data flow which leads to high bandwidth utilization.
(This also happens whenever same screen/window is opened repeatedly).

FYR i have attached screen shots for  single  user session in both idle and
active state.

Urging you to check the same and guide us further to work on frames
transferred over n/w and how to tune it ?

Re: Required help for reducing High Bandwidth Utilization of Guacamole

[Manoj Patil]

Dear Mike/Nick,

For your below question, PF below reply.

Sean makes a really good point, and, really, it brings us back to one of
Mike's questions, Manoj: what problem are you trying to solve?  Are you
seeing congestion on the network when you use Guacamole?  Is the Guacamole
connection unreliable or slow or choppy?  Are you seeing high resource
utilization for the Guacamole components or the web browser?

*--Our problem is high bandwidth utilization (around 90 kbps per user
connection) and we want to reduce this anyhow. Because we have only 50 mbps
MPLS link and we have deployed and running more than 600 user sessions in
parallel. So this bandwidth is not sufficient and s/w gets slow with
degraded performance. *

*--Is there anyway using which we can reduce this bandwidth (90 kbps) to at
least 10-20 kbps ?  or can we increase tunnel keep alive checking timeouts
at guacamole client and server side so as to reduce frequent data transfer
over network.*

*--If so please do let us know. this will greatly appreciated and our
clients will be more happy to use our solution.*

Re: Required help for reducing High Bandwidth Utilization of Guacamole

[Manoj Patil]

Hi nick,

Yes , I am seeing encoded images at idle connection and frequently packet
send recive ACK and SYN through server to client and vice versa .

I am  seeing high resource utilization for the Guacamole components on the
web browser.

I am also cross check bandwidth utilization RDP with using MSTSC ActiveX
control its too less (1.3 kbps) in running mode . in idle mode they can not
utilized network .

Re: Required help for reducing High Bandwidth Utilization of Guacamole

[Manoj Patil]

The only thing that I noticed is that there is no compression between the
server and the client. Meaning that full sized base64 encoded PNG images
are send to the client, which causes a high network load (~1.8mb/s)

Mike,

I am really see on chrome when I am open a forms or any gui  those are  see
at client side network tab.
I think this is rendring.

Hi mike

Help me in that matter how I am decrypt the tcp packet. And find out what

I am using domain name with https connection.

Hi ,

 I am see in browser Guacamole send full-screen images from the server to
the client.
Can this is utilized bandwidth?

[Manoj Patil]

Thanks Mike ,

I am continuously check http request and capture the packet I see ACK is
continuously from server to client side and client to server s oh side in
idle session .

Please help us in how can I check at my end to find out where is the
problem of high bandwidth utilization.

Dear mike,

In last reply of  Nick he said there is any traffic of audio and I am check
the http traffic and send you I see the the word in this traffic is
guac_audio . but I am not enable the audio settings .

Please check http request and guide us

Hi all

Today I am see in tcp and web socket packet there is audio traffic is
found  but I am not enable the audio I think by default audio is enable
when guacamole is install .

Please guide us how to disable the audio communication from server to
client and viceversa .

I am using mysql authentication.

Re: Required help for reducing High Bandwidth Utilization of Guacamole

[Manoj Patil]

Hello Mike,

We have investigate further and there in we found that there's an
continues ACK/SYN/PING traffic flows between server and client for an
absolutely idle session.

Due to which number of packets and in turn data exchange
increases continuously for an absolutely idle session.

Can you please guide us on how to stop continues server PING/NOP/ACK/SYN ?

can we configure some parameters in guacamole-client to achieve this ?

Re:

Yes, we have verified the same that local browser cache is caching .js
files not downloading them from server for subsequent requests.

But we also observed that Xhr,images and css files always get download from
server with transfer size almost 3 MB per login page request.

PF below attached screenshot FYR.

Is there any way to have these files also locally cache so as to save
network bandwidth ?

Re: Scoket in CLOSE_WAIT

[Manoj Patil]

Hello Nick,

Technically we can understand what you are trying to tell us and we are
appreciating your reply too.

But after digging so much we haven't found any work around for our problem
which we are facing.

Also we have deployed our solution on production for lots of our clients.

so at least at this stage we need some kind of work around for problem
instead of root cause solution.

Will you please guide us on how to initiate socket close/disconnect request
to xrdp from guacamole to release CLOSE_WAIT STATE ?

Your guidance will be greatly appreciated.

Re: Scoket in CLOSE_WAIT

[Manoj Patil]

It seems that XRDP is not cleaning sockets(CLOSE_WAIT state)  as because
it's not receiving last close acknowledgment from guacamole/client side.

Can we initiate socket close from guacamole periodically ?

Re: User disconnected

[Manoj Patil]

Yes, i am clicking on “Logout” with guacamole at that time what happen when i 
am reconnecting through guacamole usernames and password the message is user is 
connected .

At that time i am refresh the guacamole link means 
“http://domainname:8080/guacamole/ <http://domainname:8080/guacamole/> “ and 
then connect that time successfully connected.

so my question is is any chance to refresh link when i am logout with guacamole.
