SCW Version 1.9

This is certainly due to the way we are handling remote command executions on Windows.

Can you run scw -D logs 14a75140-43df-4cdf-b1db-586042aacbac (with debug), you should get the command we try to run, something like ssh 1.2.3.4 /bin/sh -c dmesg

Then can you try to run this command manually from your shell and paste us here the result of these two commands ?

@QuentinPerez, I think we should bullet-proof the utils.SSHExec() function for Windows

Can you try to run the four following commands and tell us if any of these succeed:

ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -l root 163.172.142.208 -t -t -- /bin/sh -e -c "\"dmesg\""

ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -l root 163.172.142.208 -t -t -- /bin/sh -e -c "dmesg"

ssh -o UserKnownHostsFile=NUL -o StrictHostKeyChecking=no -l root 163.172.142.208 -t -t -- /bin/sh -e -c "\"dmesg\""

ssh -o UserKnownHostsFile=NUL -o StrictHostKeyChecking=no -l root 163.172.142.208 -t -t -- /bin/sh -e -c "dmesg"

I think we have a least a bad path on windows: /dev/null should be NUL, I also have a doubt about the double-escaping

commented

All four work. /dev/null is expected to work from Bash and I think ssh.exe has special handling for it.

commented

works fine now
