Connecting to windows remote machine with parallelly::makeClusterPSOCK hangs #96

Tadge-Analytics · 2023-01-22T04:12:29Z

When I run the following code...
It hangs and doesn't end up connecting.

This is me connecting to another Windows 11 machine.
I have been able to SSH into it.

Any tips?

Here is a video of me troubleshooting with dryrun = TRUE
https://youtu.be/857DRD-k-DA

ip <- "10.0.44.224"

# Path to private SSH key that matches key uploaded to DigitalOcean
ssh_private_key_file <- "/Users/Julian/.ssh/id_rsa"

# Connect and create a cluster
cl <- 
  parallelly::makeClusterPSOCK(
    ip,
    user = "Julian",
    rshopts = c(
      # "-o", "StrictHostKeyChecking=no",
      # "-o", "IdentitiesOnly=yes",
      "-i", ssh_private_key_file
    ),
    master = "10.0.44.234",
    homogeneous = TRUE,

        dryrun = TRUE
    # dryrun = FALSE
    
  )

Hi. as a starter, make sure you can do what's in Section 'Failing to set up remote workers' of https://parallelly.futureverse.org/reference/makeClusterPSOCK.html.

Thanks for the video, but unfortunately, I cannot really see the text, because I've only got a 14-inch screen, so the fonts are too teeny. But, as a follow up on the above tests, look at the commands outputted when you do dryrun = TRUE. On Linux, it's something like:

'/usr/bin/ssh' -R 11045:10.0.44.234:11045 -l Julian -i /Users/Julian/.ssh/id_rsa 10.0.44.224

but you'll get another ssh command if you do this from MS Windows. Make sure you can cut'n'paste the call you see and that get's you into the remote machine. Does that work, or does it stall there? It could be that the reverse tunneling -R causes problems with MS Windows on the other end (just guessing).

HenrikBengtsson · 2023-01-22T04:34:16Z

Also, you could set options(parallelly.debug = TRUE) to get more output. It should show where it stalls.

Tadge-Analytics · 2023-01-22T04:36:18Z

Thanks for these @HenrikBengtsson I'll give them a quick try

Tadge-Analytics · 2023-01-22T04:39:04Z

I did try the 'Failing to set up remote workers" section...
The one-line thing works...

I get the following debug output... I'll take a look into it

When I try to run the code suggested when I do dry run... Interestingly the quotation marks break the connection process... when I take those quotation marks out it connects fine

Tadge-Analytics · 2023-01-22T04:48:13Z

When I try the full command (first time including the quotation -just to show what I get when I copy and paste verbatum... second time with some quotation mark cleaning up) I get the following:

HenrikBengtsson · 2023-01-22T04:50:31Z

Can you paste in as plain text instead of screenshots? Then I can cut'n'paste from it

Tadge-Analytics · 2023-01-22T04:52:34Z

Sure thing. Just let me know which ones you need.
Here is what dryrun instructs me to paste in...

  "C:\WINDOWS\System32\OpenSSH\ssh.exe" -R 11750:10.0.44.234:11750 -l Julian -i /Users/Julian/.ssh/id_rsa 10.0.44.224 "'C:/PROGRA~1/R/R-42~1.2/bin/x64/Rscript' --default-packages=datasets,utils,grDevices,graphics,stats,methods -e 'options(socketOptions = \"no-delay\")' -e 'workRSOCK <- tryCatch(parallel:::.workRSOCK, error=function(e) parallel:::.slaveRSOCK); workRSOCK()' MASTER=10.0.44.234 PORT=11750 OUT=/dev/null TIMEOUT=2592000 XDR=FALSE SETUPTIMEOUT=120 SETUPSTRATEGY=sequential"

HenrikBengtsson · 2023-01-22T05:06:59Z

AFAIU, you said:

C:\WINDOWS\System32\OpenSSH\ssh.exe -R 11750:10.0.44.234:11750 -l Julian -i /Users/Julian/.ssh/id_rsa 10.0.44.224

workers, but then, in your last screenshot, you got an error:

C:\WINDOWS\System32\OpenSSH\ssh.exe -R 11750:10.0.44.234:11750 -l Julian -i /Users/Julian/.ssh/id_rsa 10.0.44.224 'C:/PROGRA~1/R/R-42~1.2/bin/x64/Rscript' --default-packages=datasets,utils,grDevices,graphics,stats,methods -e 'options(socketOptions = \"no-delay\")' -e 'workRSOCK <- tryCatch(parallel:::.workRSOCK, error=function(e) parallel:::.slaveRSOCK); workRSOCK()' MASTER=10.0.44.234 PORT=11750 OUT=/dev/null TIMEOUT=2592000 XDR=FALSE SETUPTIMEOUT=120 SETUPSTRATEGY=sequential
The system cannot find file specified.

So, maybe it cannot find 'C:/PROGRA~1/R/R-42~1.2/bin/x64/Rscript' on that other machine. I'm a bit puzzled why it does not use 'Rscript' here. Oh... wait, I see you're using homogeneous = TRUE. Remove that one (or explicitly set it to homogeneous = FALSE).

And now I also see that you're setting master = 10.0.44.234, which explains why it shows up in the reverse tunnel option and MASTER=10.0.44.234; that causes the workers to try to connect back via that IP number, which requires setting up port-forwarding in the firewall, instead of the reverse SSH tunnel that is always on localhost and that circumvents the firewall.

So, retry with:

cl <- parallelly::makeClusterPSOCK("10.0.44.224", user = "Julian",
           rshopts = c("-i", ssh_private_key_file), dryrun = TRUE)

and see if the proposed full call works, i.e. doesn't give that error.
