Hi,  
i want to use the [https://flows.nodered.org/node/node-red-contrib-telnet-client](https://flows.nodered.org/node/node-red-contrib-telnet-client) Telnet Node.  
When i install i can setup the telnet connection, but when i want to deploy it i get an error that says that the telnet connection node is missing.  
After rebooting node red the telnet connection settings are gone and i cannot use the package.

Can anyone help me?  
Is there a way to report bugs direct on a package?

Do you mean you get the Flows Stopped Due To Missing Nodes message?  
If so then open a terminal and go to your .node-red folder and run  
`npm install node-red-contrib-telnet-client`  
and if, at the end, it says it has failed then copy/paste the output here please. When pasting it in use the `</>` button at the top of the forum text window.  
If it appears to have succeeded then stop node red and start it in the terminal and post that log here too.

There was just an update in the last couple of minutes (but the page says 2 months ago).  
Now i have V 1.0.1 and this bug is gone - it's not working (doesn't read the telnet data) but i have no more error.

Unfortunately the node does not seem to have a github repository and so there is no obvious way to report a problem. You could try contacting the author directly.

Do you have to use telnet, can you not use ssh?

Jeah i sadly have to, ssh is not supported.  
now the package bugs after rebooting and says that 2 other nodes of the package are missing - very weird.  
Looks like this:

Install log looks like so:

Have you searched the flows site and the forum for telnet to see if there are alternatives?

I could try to use the tcp node but i'm not sure how to send sth with the tcp node.  
I already tried but it didn't work

```auto
[{"id":"15b71cd6.054763","type":"inject","z":"ea4157b9.422548","name":"","props":[{"p":"data","v":"MCa","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","x":640,"y":500,"wires":[["7267fa9d.915f24"]]},{"id":"7267fa9d.915f24","type":"tcp out","z":"ea4157b9.422548","host":"192.168.178.84","port":"23","beserver":"client","base64":false,"end":false,"name":"","x":920,"y":500,"wires":[]}]

```

And the tcp in Node does not only listen but it blocks all other connections - so telnet would be better.

Also i could not find any contact information about the author of the telnet package.

When i install the package with the terminal i see a lot more output - also some errors (probably the reason why it doesn't work)

Then i had to enter (because i couldn't build bcrpyt)  
`npm i request`

Then i was able to run  
`npm install bcrypt@5.0.0`

and after that  
`npm install node-red-contrib-telnet-client`

but it was missing in the ui and also not there after restarting the container. so i tried the same command as seen in the ui.

`npm install --no-audit --no-update-notifier --no-fund --save --save-prefix="~" --production node-red-contrib-telnet-client@1.0.1`

And i have the problem i had before `npm i request`. (Some errors building)

...... When i install via terminal of the Docker container it's missing in the UI and when i install via the UI it's broken after deploy like in post before.

You don't need to worry about the apparent errors, the fact that it ends with

```auto
+ node-red-contrib-telnet-client@1.0.1
updated 1 package and audited 1071 packages in 31.975s

```

means that it installed ok.  
[Edit] though it might be worth while removing it then re-installing, since that just updated a package that was already installed  
`npm remove node-red-contrib-telnet-client`

I was just trying to use this node as well and was having issues. I'm guessing it has to do with some references in some of the files. I see this error:

- Error: Cannot find module 'C:/Users/Charles-Andre.HOME/source/repos/telnet-engine/index.js' (line:4)
- Error: Cannot find module 'C:/Users/Charles-Andre.HOME/source/repos/telnet-engine/index.js' (line:4)

I'm not Charles-Andre, I'm guessing that is the author.

The problem was a local File Path in 2 of the Nodes. This was fixed by the dev ([https://github.com/CABrouwers/node-red-contrib-telnet/issues/1](https://github.com/CABrouwers/node-red-contrib-telnet/issues/1)) also i had to request refresh in order to update it in Node Red.  
Problem solved.

And much thanks to @Colin for his very fast reply - i'm not used to this in forums.

I am the node owner. Thanks for your help. I have now created a Github repository and yesterday I uploaded a corrected version on npm (1.0.4). However, the version hasn`t been picked up by node-red yet. If anyone has an idea why, please let me know.
