Replit's terminal provides a lot of features that are very similar to any Linux terminal. At first, I thought the site was using SSH to link a remote terminal to the website but when I ran the following command service ssh status, then the output was
* sshd is not running. This indicates that the site is not using SSH to link the terminal.
Does this mean the developers have created a custom terminal for their website or is there a way to show this output for remote users for security purposes?

I have PyCharm Pro. I am trying to do remote development on a server. I have read the following Jetbrains tutorials:
Deploying Applications
Remote Development on Raspberry Pi
as well as the very helpful tutorial:
Remote debugging with pycharm the missing tutorial
While I seem to be able to set everything up, authentication fails when I try to connect to the remote server using the 'SFTP' protocol. I can make an SSH and SFTP connection from the CLI in a terminal so I know the ssh configuration settings are correct. However, in my case authentication requires ssh and having a Yubi key connected to my laptop. Does that make a difference?
Has anyone had a similar issue? If so, how did you resolve it?
On MacOS the challenge is where the IDE is getting it's ssh socket agent. To make this work in my case I have to launch the PyCharm Pro IDE from a terminal.
Go to '/Applications/PyCharm.app/Contents/MacOS' directory and launch with './pycharm'
I found a strange thing when using ssh -X to connect to two servers.
Ubuntu16.04 is installed on one server, while Ubuntu 18.04 is installed on the other. I upload a simple shell script as following to both servers:
#!/bin/bash
tab=" --tab"
options=()
cmds[1]="echo Banana"
cmds[2]="echo Cat"
for i in 1 2; do
options+=($tab -e "bash -c '${cmds[i]} ; bash'" )
done
gnome-terminal "${options[#]}"
exit 0
You know this script will open a new terminal window on server with two tabs. One tab will print "Banana", and the other tab will print "Cat".
Then I using ssh -X to remotely login into the first server (Ubuntu 16.04) and execute this script on server, I got a new terminal opened with two tabs on my pc. That is I saw the remote terminal GUI of server on my own computer. However, if I repeated these steps on the second server(Ubuntu18.04), I will got nothing to show on my computer.
The I execute commandgedit on the ssh login terminal when using ssh -X to login into both servers, I could see the GUI on my computer for both the cases.
I guess Ubuntu 18.04 cannot transport terminal's GUI through ssh -X to my pc. I was very confused about this. Could you please to explain the reason? And BTW, how can I see terminal's GUI of server in this case? Thanks a lot!
ssh -X doesn't transport a terminal. It tunnels a X11 connection.
X11 in its core is a network based display protocol. The programs (X clients) connect to a X server (a program running on your local machine) and instruct it to create windows and draw stuff to it. There is no graphical rendition of any kind anywhere else than the X server!
ssh -X does not operate like Windows Remote Desktop, where there is an actual graphics environment running on the remote machine. Hence if you create two separate ssh -X connections (maybe even from different machines), these connections are completely independent from each other. Hence you cannot use ssh -X to connect with a preexisting X session!
What you want is either Xvnc or Xpra, where the graphics environment is actually run on the remote machine, and only the output is transferred to your local machine.
I need to connect to my university server (S) from home using my laptop (L). Since I am off campus (and my VPN does not work for some reason), I am required to first login (SSH) to my desktop (D) at the university, and then connect to S (since the server only accepts connections from computers on the campus network).
I am using Cygwin on Windows 8. I would like to know how I can create a script to auotmate this process - currently I have to manually SSH from L to D, and then again from D to S. I am new to unix.
Any help will be appreciated. Thanks.
--- Edit ---
Specifically, I would like to know how I can automate this process so that I don't have to enter my password every time.
ssh accepts a command to execute at the remote host after connecting. You can use that to launch a second ssh session:
ssh -t D ssh S
You'll be prompted for your desktop password first, then for your server password.
By the way, I recommend looking into GNU screen if you're not already using it. It prevents losing any work in case your SSH connection drops out.
To automate this even more, stick it in a bash file called "connect-university.sh":
#!/bin/bash
ssh -t D ssh S
You can then run that file from the Cygwin commandline via:
./connect-univiersity.sh
Note that the ./ part is essential, as Cygwin doesn't usually look for executable files in the current directory for security reasons.
I want to run my application (based on OPEN API) on a server on which Bloomberg Terminal is not installed. But I have to pass by a Bloomberg server.
Look at "Figure 7-2: Server API: Server Mode: Authorization by IP Address" on page 80 of "blpapi-developers-guide.pdf".
Please let know how this can be done.
Or how setup EMRS in order to allow an application to be given entitlements and services to consume?
Thank you.
IMPORTANT: This method is not compatible with Bloomberg licence agreement. Use it only for debug purposes.
Download PasPort application from here and install it. PassPort is a simple port forwarding utility. The program runs as an NT Service. It is easily manageable with a simple Windows GUI.
For example your computer with Bloomberg terminal has ip 192.168.8.40, then you need to setup PassPort application as following:
Don't forget to add a rule to the firewall in Windows:
Now you can access terminal from any computer on the local network. Furthermore, you can setup access to terminal behind a firewall.
For example you can run on computer with ip 192.168.8.41 the such command:
java -jar SimpleFieldInfoExample-3.6.1-0.jar -ip 192.168.8.40 -p 8194
And it is working now!
Of course you also need to run bbcomm.exe on Bloomberg terminal using Start menu:
It is possible to activate bbcomm without any window using command:
java -jar SimpleFieldInfoExample-3.6.1-0.jar -ip localhost -p 8194
Or you can launch the "Bloomberg API DEMO" application.
There is a simpler way to pass a port:
netsh interface portproxy add v4tov4 listenport=8194 listenaddress=192.168.0.101 connectport=8194 connectaddress=localhost
I need to run some scripts in a windows remote machine from a terminal linux, I've tried using telnet however in the windows machine it's unable and there isn't installed a ssh server. So I need other way to run the command remotely without a graphical interface.
I have the possibility for run the command from a windows machine, however I need to open a SSH Tunnel to see the remote machine, I've used psexec but it didn't work for me.
Do you have access to install software on the remote server?
Your SSH client will not be able to connect to the remote machine unless that machine is running an SSH server to respond to your client's connection request.
There are a number of possible options for SSH servers to run on Windows.
(Google for ssh server windows)
Because SSH gives an external user some access to/control over your server it is designed to be a secure tool. I would therefore recommend using an SSH server which is still actively maintained, and keep it up to date. Servers which are old and no longer supported are are likely to contain known security issues which may never be addressed, thereby leaving your server vulnerable.
There are a number of good free open-source solutions for this, so you shouldn't need to buy anything.
In the past I've worked with Windows machines running Cygwin, with the OpenSSH ssh server installed. Depending how much of the Cygwin system you choose to install, it can make the target Windows host rather like logging into another Linux box in terms of environment.
You can download the installer for Cygwin from http://www.cygwin.com/
