Telnet autorization

IR.AddListener(IR.EVENT_RECEIVE_TEXT, IR.GetDevice('AV_Driver'), function(text)
{
 IR.Log("text = "+text);
 
 if (text.indexOf('User') != -1)
 {
 IR.Log("User >")
 IR.GetDevice('AV_Driver').Send(['admin',13,10]);
 } else if (text.indexOf('Password') != -1)
 {
 IR.Log("Password >")
 IR.GetDevice('AV_Driver').Send(['admin',13,10]);
 }
})

I too am having a similar issue. I have used the examples above however my telnet server will respond with 'box' and #. I am running telnetd on Ubuntu and I'm trying to use telnet to remotely control parameters on the computer from my iRidium control panel. 

When using a terminal program, this is what I get:

Ubuntu 20.04 LTS
NUC-test login: iainbrew
Password:

I modified the code above to be:

IR.AddListener(IR.EVENT_RECEIVE_TEXT, IR.GetDevice('AV_Driver'), function(text)
{
 IR.Log("text = "+text);
 
 if (text.indexOf('NUC-test login:') != -1)
 {
 IR.Log("NUC-test login:")
 IR.GetDevice('AV_Driver').Send(['iainbrew',13,10]);
 } else if (text.indexOf('Password:') != -1)
 {
 IR.Log("Password:")
 IR.GetDevice('AV_Driver').Send(['super_secret_password',13,10]);
 }
})

However all I get back in log is 'box' and #

I once solved this with another device which only required password, by sending the password in every command i.e.

'password',0x0D,'command_string',0x0D
 

But this doesn't work for Ubuntu login (with username and password)

I think you have now confused SSH and TELNET - these are different protocols

Hi Aleksandr - I confirm I installed telnetd and tcpd on the Ubuntu machine and have been using Telnet to connect to it deliberately (as I believe SSH isn't supported by iRidium yet). I also tried sending a packet to the Ubuntu computer on port 23 via TCP and it sends back the telnet handshake request. I believe this is where I am stuck - the handshake request (escape #) is coming back to iRidium but not showing login etc as the handshake is not completed. 

Some other thoughts to try (and happy to take your advice) would be to:

1) Have iRidium call a script (the interface will run in Windows) which instead can be executed on the windows machine in the background to trigger the 6x Ubuntu computers to shutdown

2) Install iRidium Server on the 6x Ubuntu machines and have them locally execute commands. I have tried this, but have not been having luck installing iRIdium on Ubuntu 64 bit. 

The command I am trying to issue is "sudo shutdown -P now" followed by admin password. My ultimate goal would be to use iRidium server to send through commands to Zoom to have them joined a specified call (i.e. instead of http:// I would use zoom:// to trigger the app to load and connect to the correct meeting ID and meeting password).

This is all part of a system I am building to have a master zoom computer (Windows, Host) whereby 6x slave devices (Ubuntu on NUC) can connect as participants to the main call with various video inputs for remotely directed education. 

1. You can use IR.Execute (https://dev.iridi.com/Systems_API/en#IR.Execute) for call to script.

2. This is bad idea, because it will be 6 different licenses (1 license = 1 server).

For shutdown command you should make a bash script with permissions.
