Hi, thanks for sharing this issue and logs.

To help figure out what’s going on, could you please provide the following?

  • What version of the remote ssh extension are you using?
  • What operating system is your remote machine?
  • Have you tried clicking the reinstall server button, and is it this error every time?

Thanks!

8
  1. [version] remote ssh extension = “remote-ssh-1.0.8” and “remote-ssh-1.0.11”
    2, operating system is your remote machine
    |Distributor ID:|Ubuntu|
    |—|—|
    |Description:|Ubuntu 20.04.6 LTS|
    |Release:|20.04|
    |Codename:|focal|
  2. Have you tried clicking the reinstall server button
    [yes] I also delete cursor server folder in the remote machine
10

Could you also share the output of running cat /home/shicc/.cursor-server/bin/88a47f0edd42a2ba73afb018ada9fe9eda7df750/node /home/shicc/.cursor-server/bin/multiplex-server/1f3345b44ce6674a5b8be03c6dceb7e47d7d58164d5611843746561cfb16f620.js on your remote machine?

It would be helpful to know what is actually being written into this file. Thanks!

I run the code
"cat /home/shicc/.cursor-server/bin/88a47f0edd42a2ba73afb018ada9fe9eda7df750/node"
too much binary code, can you tell me what key info you want? Node.js is “v20.18.2”

17

Thanks, yes meant to ask for just the script file, not the node binary.

It looks like there is some sort of escaping / encoding issue that is causing corruption of the script. Version 1.0.12 switches how the encoding is performed to make it more resilient. Could you try upgrading to that version and share whether it works for you? Thanks!

18

Sure I delete all versions and configs in my computer and then reinstall cursor
It seem ok now
thanks you~
