Is your /tmp noexec by any chance?

@uishon you might have another password prompt waiting for you in a terminal. The terminal should have popped up by itself. But if it didn't check the terminals in the drop down of the Terminal panel.

[Stephen9s]

We are using PKI, which works direct but through the jump box, it does not. I also tried jumping through a jump box to a box that would require a password and was prompted. The error that appears is that the server isn’t x86_64 or something like that.

If you have to use a password to log in, then you will have to set remote.SSH.showLoginTerminal.

See https://code.visualstudio.com/docs/remote/troubleshooting#_enabling-alternate-ssh-authentication-methods for details

Let me know whether that helps

[uishon]

That helped. Thanks. I'm now connected and able to work remotely.

@uishon How are you dealing with the constantly changing IP address of Hyper-V? Everything works on my end except every time I wake the PC from sleep/restart, they ip address of the VM in Hyper-V is different and I have to change the host in ssh config.

[uishon]

I'm using a dns name. In my case it's the hyper-v Linux name with a ".
mshome.net" suffix. Works wakeup or reboot.

Okay thanks. I have a a linux vm called dev but ssh-ing to [email protected] but cannot resolve hostname. Am I doing something wrong?

[jovinbm]

I figured it out. I was using the hyper-v name given to the machine instead of the hostname of the linux machine. Works now. Thanks.
