My desktop is behind a router I don’t have access to, but I wanted to be able to RDP into it.

After some searching I found this article about how to do just that!
https://eviatargerzi.medium.com/how-to-access-rdp-over-ssh-tunnel-c0829631ad44

I already had a instance of lightsail on AWS so I just used it.

ensure openssh-server is installed, if not:

sudo apt update
sudo apt install openssh-server

Edit the sshd_config

sudo vim /etc/ssh/sshd_config

scroll to the bottom. Type “i” for insert then add the following lines

#Allow RDP Tunneling
GatewayPorts=clientspecified

To save: esc then “:wq” (command, wright, quit)

You can check that it’s in there by running

cat /etc/ssh/sshd_config | grep Gate

response:

#GatewayPorts no
GatewayPorts=clientspecified

Configure RDP Host

Eviatar suggests using Plink(Putty Link) on your host computer

Download: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

After installation, you may need to set the path.

You may be able to run

set PATH='C:\Program Files\PuTTY\plink.exe'

Close and reopen command prompt. If that doesn’t work, from the start menu search bar look for “environment variables” and open “Edit the System Environmental Variables”

Click “Environment Variables…” button under the Advanced Tab

Under “User variables” select “Path” then click edit

Click new and add C:\Program Files\PuTTY\plink.exe

Click OK, then restart command prompt and type plink to see if the system found it.

plink <user>@<ip or domain> -i <c:/users/user/.ssh/private_key_from_aws> -P 22 -2 -4 -T -N -C -R 0.0.0.0:12345:127.0.0.1:3389

-i – Set key location
-P – Set port
-2 – Force protocol version
-4 – Force use of IPv4 (and not IPv6)
-T – disable putty from attempting to allocate a pseudo-terminal at the server
-N – Prevents Putty from attempting to start a shell or command on the remote server
-C – Enables compression
-R – forward remote port to local address: Here port 12345 will be forwarded to 3389

This can be simplified using OpenSSH

Follow instructions from microsoft to install:
https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse?tabs=gui

  #aws server
  Host 123.123.123.123
    User bitnami
      IdentityFile ~/.ssh/id_rsa
      IdentitiesOnly yes
      ServerAliveInterval 60
      ServerAliveCountMax 10

Adding ServerAliveInterval sets the number of seconds the client will wait before sending a packet to the server to keep connection alive

ServerAliveCountMax sets the number of times the client will try to keep connection alive.

You can also add ClientAliveInterval to etc/sshd/ssh_config on the server

ClientAliveInterval 60
ClientAliveCountMax 10 #default is 3

Be sure to open up 3389 on your server’s firewall

ssh 123.123.123.123 -2 -4 -T -N -C -R 0.0.0.0:12345:127.0.0.1:3389

NPM documentation suggests installing from NVM since the node installer could cause permission issues down the line.

There’s an nvm port: https://github.com/coreybutler/nvm-windows

Once installed, open a terminal window (or close and reopen)

nvm install node

Search for Environmental Variables in Windows Search. This will open System Settings, click Environmental Variable, Edit “Path”, Create new and browse to your nvm install location for me it was C:\Users\USER\AppData\Roaming\nvm\v19.9.0

Save, then close your terminal window and open it again, so the new paths update.

npm --version

Download NHDPlus HR Data

You can find the Data on the National Map:

https://apps.nationalmap.gov/downloader/

Zoom into the area you need data for, check Hydrography, NHDPlus High Resolution, then HU-4 Subregion (HUC 4 areas) unless you need a smaller area then HU-8.

Click the big blue button Search Products

Download the products you need. Choose the “Zip” version which is the GDB. If you get the z7 version you’ll download the Raster version.

Once downloaded, unzip, then drag the GDB folder to the database folder in the Catalogue panel.

Under Hydrography, drag NHDFlowline to your contents panel, then drag the NHDPlusFlowlineVAA table to contents as well.

On Contents panel, right click on NHDFlowline, under Joins and Relates, click Add Join.

for input Join Field, select NHDPlusID.
For Join Table, select NHDPlusFlowlineVAA then add NHDPlusID to the Join Table Field if it doesn’t auto populate.

Now that the polypath has the data we need, right click NHDFlowline in Contents panel and select Symbology to open its panel.

When I first started working with tapered streams, I would use “Mean Flow Volume,” but I’ve found using the TotalDrainageAreaSqKm creates better results especially for delta areas where rivers split.

In the Symbology panel, select TotalDrainageAreaSqKm then take a look at the Histogram

It looks like there are values in the -9999 (likely meaning a stream segment without information available), then a tiny percentage of streams with the largest area. To fix this, double click on NHDFlowline in Contents panel to open its properties. Select Definition Query, hit the +, and add a new query Where upstreamCumulativeAreaSqKm is greater than 0 AND UpstreamCumulativeAreaSqKm is less than 400.

Now when you pull up the Histogram in Symbology, it will present something much more meaningful.

Set Classes to 5, switch to Manual Interval, then adjust the Histogram breakpoints until it look right.

Now we’ve got to add back those major trunk rivers. Right click on NHDFlowline, click copy, then right click on the map name at the top (unless you renamed it it may be “Map”) select Paste. Rename this feature set by clicking on the words once. Change its name to NHDFlowlineBigRiver

Double click to enter its properties, select Definition Query. Then edit the definition Where TotalDrainageArea is greater or equal to 100 .

Go back to your Symbology panel, create 5 classes between 1.5 and 2pt, then change adjust values in histogram as needed.

Part 2 coming soon.

I’m sure there’s a better way to convert a sketch layer into coordinates, but this worked for me.

Use Geoprocessing tool: Layer to KML

Then use KML to Layer to import it back in with the coordinate system the map is in.

Open the features table, calculate:

New field: Lon

Lon = shapeToY(!Shape!)

Code Block:

def function(shape):
   point=shape.getPart(0)
   return point.Y

Repeat for the calculation for x
