Nabble apparently stripped out the Nginx config portion from its email
to the list. For the sake of those subscribed normally (and for the
sake of the mail archives) here is the portion which was stripped:
server {
listen 80;
...
...
client_max_body_size 1M;
location {
otherstuff
}
}
For reference:

Re: [SSH] Guacamole only allows <1MB file uploads
I do use nginx to proxy my Guacamole. That was the issue! Resolved by adding the following to my /etc/nginx/conf.d/domain.conf file. -- View this message in context: http://apache-guacamole-incubating-users.2363388.n4.nabble.com/SSH-Guacamole-only-allows-1MB-file-uploads-tp410p412.html Sent from the Apache Guacamole (incubating) - Users mailing list archive at Nabble.com.

If you're using Nginx to proxy the Guacamole connection, that's a more likely cause, as it's default upload limit is 1 MB, which matches what you're seeing exactly. Other than that, Guacamole itself imposes no such limits. - Mike
[SSH] Guacamole only allows <1MB file uploads
Hello, Guacamole only allows for files less than 1 mb to be uploaded over an SSH connection in my setup. Anything over 1 mb gives me a permissions error. I have been unable to find any permissions errors in my tomcat log, in debug output from guacd, or in my SSH secure log when set to debug. I'm using the MySQL + LDAP authentication plugins, and the behavior seems to be present regardless of whether these plugins are enabled or not, used in combination, or not. My current theory is that there is some sort of file size limitation in tomcat that is preventing me from being able to upload files larger than a certain size, but I'm not sure what that limit specification is or how to modify it. My attempts to modify any sort of filesize limit via web.xml files have been unsuccessful so far. (referring to this as a guide on file size limitations: http://tecadmin.net/increase-tomcat-upload-file-size-limit/) Looking to the guacamole forums for guidance and consultation. Let me know if any specific information is needed. Please advise, and thanks in advance! Currently using 0.9.10-incubating.

Re: Problem guacd timed out.
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? - Mike On Wed, Feb 15, 2017 at 9:46 AM, Jorge Camara wrote: > Hi people. > > I did not receive any response and would appreciate it if I had. > I would also like to know if anyone has at least been through this. > > Best Regards. > Jorge > > > > 2017-02-06 10:08 GMT-02:00 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.

Hi people. I did not receive any response and would appreciate it if I had. I would also like to know if anyone has at least been through this. Best Regards.
