# Debugging
In the case where KasmVNC crashes and a backtrace is produced. Developers need a way to make the backtrace useful for debugging. This document covers where the backtrace is logged and how to use a debug symbol package and gdb to gain more information from the backtrace, such as filename, function name, and line number.
## Test Symbolization
If you want to induce a crash to test that you can symbolize a backtrace you can start KasmVNC and then issue the following command.
killall -SEGV Xvnc
This will cause KasmVNC to terminate with a backtrace similar to the following. You will find the backtrace in the log file at $HOME/.vnc/$HOSTNAME:$DISPLAY.log where HOME is your user's profile path, HOSTNAME is the hostname of the system, and DISPLAY is the assigned display number for the session.
(EE)
(EE) Backtrace:

## Debug Symbol Package
In order to make use of this backtrace, you will need to symbolize the backtrace. Each build of KasmVNC produced by our pipelines comes with a corresponding debug symbol package that can be downloaded. You need two pieces of information to get the package, the git commit ID of KasmVNC and the MD5 sum of Xkasmvnc binary on your system.
The git commit ID can be found using Xvnc -version:
ubuntu@matt-dev-vm-1:~$ Xvnc -version
Xvnc KasmVNC 0.9.94002f39917dca0ad82ac0c29a75c723b538b32b - built Feb 17 2022 15:21:01
Copyright (C) 1999-2018 KasmVNC Team and many others (see README.me)
See http://kasmweb.com for information on KasmVNC.
Underlying X server release 12010000, The X.Org Foundation
The MD5 sum can be obtained using the md5sum command:
md5sum /usr/bin/Xkasmvnc
57ee7028239c5a737c0aeee4a34138c3 /usr/bin/Xkasmvnc
With these two pieces of information, you can get the debug symbol package at https://kasmweb-build-artifacts.s3.amazonaws.com/kasmvnc/crashpad/[COMMITID]/[MD5SUM]/kasmvncserver-dbgsym.deb, in the above example it would be.
[https://kasmweb-build-artifacts.s3.amazonaws.com/kasmvnc/crashpad/94002f39917dca0ad82ac0c29a75c723b538b32b/57ee7028239c5a737c0aeee4a34138c3/kasmvncserver-dbgsym.deb](https://kasmweb-build-artifacts.s3.amazonaws.com/kasmvnc/crashpad/94002f39917dca0ad82ac0c29a75c723b538b32b/57ee7028239c5a737c0aeee4a34138c3/kasmvncserver-dbgsym.deb "https://kasmweb-build-artifacts.s3.amazonaws.com/kasmvnc/crashpad/94002f39917dca0ad82ac0c29a75c723b538b32b/57ee7028239c5a737c0aeee4a34138c3/kasmvncserver-dbgsym.deb")
Use wget or curl to download the debug symbol package and then install it.
wget https://kasmweb-build-artifacts.s3.amazonaws.com/kasmvnc/crashpad/94002f39917dca0ad82ac0c29a75c723b538b32b/57ee7028239c5a737c0aeee4a34138c3/kasmvncserver-dbgsym.deb
sudo dpkg -i kasmvncserver-dbgsym.deb
## Symbolize a Backtrace
With the KasmVNC binary and debug symbol package installed on the system, you can use gdb or addr2line to get more information, such as the filename, function name, and line number that the backtrace line is referring to.
Here is a single line from a backtrace. The following example shows how to retrieve additional information that can help with debugging the crash.
(EE) 8: /usr/bin/Xvnc (0x400000+0x13e674) [**0x53e674**]
echo info line ***0x53eaaa** | gdb -q /usr/bin/Xkasmvnc
(gdb) Line 223 of "/src/common/network/webudp/Wu.cpp" starts at address 0x53e674 <WuClientSendPendingDTLS(WuClient*, Wu const*, Wu const*)+68>
The following script will search the provide file for a backtrace and symbolize the entire backtrace.
#!/bin/bash
FILENAME=$1
grep "(EE)" $FILENAME | while read -r line ; do
BACKTRACE=$(echo $line | grep -Po '\[[0-9a-f]x[a-f0-9]{1,}' | sed -r 's#\[##')
echo $line
if ! [ -z $BACKTRACE ] ; then
SYMBOLIZED=$(echo "info line *${BACKTRACE}" | gdb /usr/bin/Xkasmvnc | grep "(gdb)" | grep -vP "\(gdb\)\s*quit$")
echo " ${SYMBOLIZED}"
fi
done
Using this script on the above example backtrace produces the following output.
ubuntu@hostname-1:~$ bash symbolize.sh ~/.vnc/hostname-1\:10.log

- Security - The RFB specification (VNC) limits the password field to 8 characters, so while the client may take a longer password, only the first 8 characters are sent. KasmVNC defaults to HTTPS with HTTP Basic Auth and disables the legacy VNC authentication method which is not sufficiently secure for internet accessible systems.
- Simplicity - KasmVNC aims at being simple to deploy and configure.
# Releases
Since this is a fast evolving project, the documents on the tip of master are chaning rapidly and will not match releases. Be sure to use the README and other documentation from the release branch that matches the version of KasmVNC you are using. Do not use the README from the master branch, unless you are compiling KasmVNC yourself from the tip of master. All releases starting at 0.9.3 have a branch named in the format 'release/0.9.3', for example.

%description
VNC stands for Virtual Network Computing. It is, in essence, a remote
display system which allows you to view a computing `desktop' environment
not only on the machine where it is running, but from anywhere on the
Internet and from a wide variety of machine architectures.
KasmVNC has different goals than TigerVNC:
Web-based - KasmVNC is designed to provide a web accessible remote desktop.
It comes with a web server and web-socket server built in. There is no need to
install other components. Simply run and navigate to your desktop's URL on the
port you specify. While you can still tun on the legacy VNC port, it is
disabled by default.
Security - KasmVNC defaults to HTTPS and allows for HTTP Basic Auth. VNC
Password authentication is limited by specification to 8 characters and is not
sufficient for use on an internet accessible remote desktop. Our goal is to
create a by default secure, web based experience.
Simplicity - KasmVNC aims at being simple to deploy and configure.

.TH kasmxproxy 1 "" "KasmVNC" "Virtual Network Computing"
.SH NAME
kasmxproxy \- proxy an existing X11 display to a KasmVNC display
.SH SYNOPSIS
.B kasmxproxy
.RB [ \-a|\-\-app\-display
.IR source\-display ]
.RB [ \-v|\-\-vnc\-display
.IR destination\-display ]
.RB [ \-f|\-\-fps
.IR FPS ]
.RB [ \-r|\-\-resize ]
.br
.SH DESCRIPTION
.B kasmxproxy
is used to proxy an x display, usually attached to a physical GPU, to KasmVNC display. This is usually used in the context of providing GPU acceleration to a KasmVNC session.
.SH OPTIONS
.TP
.B \-a, \-\-app\-display \fIsource-display\fP
Existing X display to proxy.
Defaults to :0.
.TP
.B \-v, \-\-vnc\-display \fIdestination-display\fP
X display, where source display will be available on.
Defaults to :1.
.TP
.B \-f, \-\-fps \fIframes-per-second\fP
X display, where the source display will be available on.
Defaults to 30 frames per second.
.TP
.B \-r|\-\-resize
Enable resizing. WARNING: DO NOT ENABLE IF PHYSICAL DISPLAY IS ATTACHED.
Disabled by default.
.SH EXAMPLES
.TP
.BI "kasmxproxy -a :1 -v :10 -r"
.B Proxy display :1 to display :10, with resizing on.
