I installed guacamole from source after a few hours of toil and trying out serveral outdated guides. But at this point I can go to the site and log into the guac web interface and connect to the guacd alright.
Though I couldn't find out what is the correct syntax to be used in the user-mapping.xml in order for me to have a root account that can have all the perms. Right now my account is only limited to joining rdps or vncs I allow within that conf.
Can someone shed some light?
I tried to create a vnc session on centos 8 but it showed the below message.
Please read /usr/share/doc/tigervnc/HOWTO.md for more information.
I followed below instructions,
and when I checked the service wasn't enabled.
I have a server setup with 8 cores and 32gb of RAM. I am using it to launch as many java applications as I can and hope to make the most efficient use of my resources. Upon launching I notice the server begins lagging fairly badly and Xtightvnc is using up 100% of my cpu. Only 1 core is being utilized while the other 7 are sitting comfortably. Is there any way to allow tightvnc to utilize the rest of the cores or is tightvnc only optimized to use a single core? If not are there any alternatives for me to access my server remotely while being able to run as many applications as possible? Thank you in advance.
I am using putty from a windows desktop to make an X tunnel so I can access my KVM VMs VNC console (I am using TightVNC) but the putty connection dies after a few minutes. I have other ssh connections from my windows box (actually using MINGW64 bash console) and it stays connected for a long time. Any idea how to sort this out?
I am trying to get a remote access approach (open source) working involving openssh and tightvnc that deals with NAT, that allows someone to remote to my server and then allows me to vnc back to their machine w/o having to mess with their firewall and allows me to use a static WAN address down the road. I've been trying to rough this out in small steps to manage the unknowns (for me, a lot:). It would appear others have gotten this to work, but am stumped.
For starters, have have gotten passwordless reverse ssh working between two windows 10 virtual machines (hyperv) on my laptop (i.e., I'm not trying to deal with port forwarding on my firewall or the static WAN address yet) but can't get the vcn to work over the reverse ssh tunnel, though it works just using the lan IP address instead of "localhost" for the reverse ssh.
I am wondering if my overall approach is flawed or not. It is:
Machine A/Person A (wants help)
currently a win10 vm
ssh client (native on win10)
tightvnc server
Machine B/Person B (help desk role)
currently win10 vm (same LAN as machine A at present)
ssh server (optional win10 add on)
tightvnc client
The idea would be Person A on machine A starts the VNC server on machine A, and connects over reverse ssh to machine B (so far so good). At that point person B on Machine B could VNC back to machine A and help.
My assumption which may be the problem is to use reverse ssh from A->B (I've tried the -L option too instead of -R), and then use tightvnc to access machine A back from B. After starting the vnc server on machine A, an example of the initial ssh command I've gotten to work from A to B is:
ssh -R 5902:localhost:5901 user@lanaddressMachineB -i ~/.ssh/id_rsa -vv
This part works. The vnc server on A has port 5902 (I have turned loopback on and off, tried listening server). I'm hoping this is something like I'm confused about which is the local host or something like that.
The error I'm getting on Machine B trying to vnc back to machine A over the ssh tunnel using "localhost::5902" is "connection has been gracefully closed". The vnc connection works if I just use the lanip of the vnc server on A from B.
There is nothing in the "tviewer.log" on either the client or the server. I've tried changing some settings in sshd_config (e.g., AllowAgentForwarding yes) with no result.
Q is my design flawed or workable? Is it the way I'm configuring things and can be addressed, possibly using a different ssh command?
Q do I need ssh server on both machines (am hoping to avoid this as means have to install it on other people's machines)?
I know there are various paid for and some free options to all of this, but am hoping to get it going.
Thank you.
