I recently installed ssh in cygwin, but when I tried to run it, absolutely nothing happens. No error, no waiting, it just goes directly to the next line in cygwin. I tried the same exact command on the same network with my friend's version of cygwin and it worked. Any ideas?
It seems others have had this problem, take a look at this thread
https://serverfault.com/questions/26150/ssh-does-nothing-no-matter-what-command-line-it-get-cygwin
It seems the recommended fix is a reinstall.

I am trying to get Autossh to work with Cygwin.
I followed this guide loosely:
http://tutorialspots.com/how-to-create-ssh-tunnel-on-windows-by-using-autossh-2984.html
I managed to get as far as setting up my ssh keys ad ssh'ing into my server. I did that by copying my windows .ssh folder into the one that Cygwin uses with the cp command, so I skipped the key-generating section of the guide since I have my own.
I installed the packages AutoSSH, OpenSSH, OpenSSL, Zip, Unzipsnd also vim.
So here's the really weird part:
I copied the ssh keys, ssh'ed into my server and all went fine. Then tried to use autossh with the -M command, but everything was gone. It's like the /usr/bin folder disappeared.
Then I saw that the installation file i got from https://cygwin.com/ also disappeared. And the shortcuts on my desktop and start menu has also deleted itself.
This has happened twice now after successfully ssh'ing into my server once. So it seems on the second attempt, everything deletes itself.
Even worse, when I try to download the installation file into my Downloads folder in my user directory, chrome says "Failed: Insufficient permissions".
Interestingly it only does this with the installation file. I can download any other files from any other location(it seems). If I tell chrome to use a different download folder, I can suddenly download cygwin again.
I am so confused.
Can anyone help?
I have installed Ubuntu 18.04 for windows subsystem for linux on windows 10, after enabling WSL in Powershell (instructions here: https://learn.microsoft.com/en-us/windows/wsl/install-win10).
I've done this before on a desktop but now I'm doing it on a laptop. I had no issues with the previous installation but this time around ubuntu will not launch. I get the ubuntu console popping up briefly before disappearing.
Also trying to run bash.exe from the command line fails silently (doesn't hang, just exits with no message), which may be related.
I'm struggling to figure this out as I have no idea where any error messages might be logged. Does anyone know how I can investigate further why this is happening?
Setup is a windows 10 Pro, os build 17134.376, everything up to date.
I'm struggling to figure this out as I have no idea where any error messages might be logged. Does anyone know how I can investigate further why this is happening?
Check with wslconfig.exe /l all registered distros, try to deregister the one you have problem with ( e.g. wslconfig.exe /u Ubuntu [^1]) and run the ubuntu.exe in your distro once again. Just a wild guess, it might be also a problem, if you have more than one copy of the linux distribution in you home directory.
[^1]: Warning: deregistering will delete all the associated files!
I want to automate the Ubuntu installation (a fully unattended installation without questions). I also want to run a script right after the installation is finished.
What I did is that I managed to have a fully unattended Ubuntu installation. I am doing this by providing a pre-seed file and using boot parameters to preseed the questions that are asked before the preseed file is loaded. The installation went okay but the problem lies with running the script right after the installation completion. I am using Ubuntu 14.04 LTS desktop version thus I am not using the late command as I have read that it won't be noticed by the installer. Instead, I am using the Ubiquity/success_command. I have the following code at the end of my pre-seed file.
ubiquity ubiquity/success_command string \
mkdir /target/dev-master/; \
cp -r /cdrom/dev-master/* /target/dev-master/; \
chroot /target bash /dev-master/SCRIPT;
The problem is nothing happens. I think the command went unnoticed as well.
I am not sure if I am approaching the problem correctly.
What am I doing wrong ?
Is there any other alternatives that might provide the desired result ? Any help would be appreciated and thanks.
I have installed (and re-installed) Octave 3 times on Windows 8, and I still can't get it right. The first and most obvious problem is that the prompt is missing; the screen only shows the flashing underscore that follows the prompt. This is not a major problem since the system properly responds to commands.
The major problem is that Octave crashes whenever it encounters a syntax error, instead of politely giving a diagnostic. This makes for extremely tedious software development.
Is there a way around this problem, or do we just have to wait for one side or the other to come up with an accommodation?
I encountered the same problem. I solved it by this:
create a shortcut to octave.exe, then right click->property-> change the "target" to something like:
C:\Program Files\Octave\Octave3.6.*_gcc*.*.*\bin\octave.exe -i --line-editing
Then it won't exit if u have syntax errors.
I don't understand the meaning of the parameters yet.
reference:
http://exciton.eo.yzu.edu.tw/~lab/?p=1121
Type octave --help can check the meaning of parameters.
-i also --interactvie, to force Octave interactive behavior.
Maybe Octave run at non-interactive mode at default, that means prompt should not be shown and it should terminate immediately when encountered error when reading a file.
I don't know if this will solve your problem, or if this is too bloated of a solution for you, but I use Octave on Windows 7 through Cygwin without any problems.
If you can't get Octave to run on Windows 8, you may consider running Octave through Linux via computer virtualization technology (virtual computer). Two, off the top of my head that you could use are VirtualBox by Oracle or VMWare Player
Once you have it installed, you can go to any number of sites that have pre-built Linux images that you can download and then run inside of Windows 8.X. Do a Google search of for 'Virtualbox images' or as 'VMWare appliances'. You can then download and use that to run the lastest version of Octave. I hope that helps.

Developing a program on OSX using Java and IntelliJ. Deals with network sockets and ICMP. Hence, the program needs to be run as root or sudo'd on OSX. Program runs fine from a terminal window outside IntelliJ under sudo. However, I would like to debug and run it from IntelliJ (V9). In IntelliJ it errors (I need root privs to enumerate network devices). I know how to pass program and VM parameters in IntelliJ but now how to hit Run and/Debug and have it run under sudo? What is needed is basically sudo java ...... MyProgram instead of java ..... MyProgram Any ideas or workarounds.
I came out with an answer and wanted to share it just in case anyone else runs into this. To solve the problem, I took my cue from what I do with QT & QT Creator when doing network programming.
On OSX, I opened up a terminal window and cd'd down to/Applications/IntelliJ IDEA 9.0.3.app/Contents/MacOS. There you will find a file called idea which launches the IDE. I ran that as sudo (sudo ./idea). That took care of permissions on anything Intellij launched and I could debug and step through my code as needed.
sudo /Applications/IntelliJ IDEA 9.0.3.app/Contents/MacOS/idea
Since this is a dev machine and I am in control of it security is not an issue in this case.
Hope it helps someone else out.
Inside a terminal:
sudo -s
give access to the root user.
from there you could run the Idea IDE using the script:
/Applications/IntelliJ\ IDEA*/bin/idea.sh
and in this way I'm able to work on network where permission errors where printed before.
Debugging of sudo programs is disallowed by the operating system unless the debugger is running as root, for security reasons.
So, even if you can figure out how to get IntelliJ to use sudo it won't do you any good.
I know this is not what OP directly asked -
In case someone needs to do this on Linux (Ubuntu), e.g. in order to update Idea, just run from command line:
sudo /usr/local/bin/idea
Only make sure once the Update and Restart is finished to actually close Idea and start it normally
I agree with #Darron, it is not recommended to execute IntelliJ with sudo.
You can execute with IntelliJ terminal instead.
I maintain my project in IntelliJ. When I need to execute a unit test that requires sudo access, I just open IntelliJ terminal and type:
sudo gradle test
Good luck!
