Unable to Specify -ohostkeyalgorithms=+ssh-dss

[arununzer]

Hello Team,

I need to use this github actions to login to a machine and to run a shell Script.

• name: executing remote ssh commands using password
  uses: appleboy/ssh-action@v0.1.10
  with:
  host: ${{ secrets.BILLING_HOST }}
  username: ${{ secrets.BILLING_USER }}
  password: ${{ secrets.BILLING_PASS }}
  port: ${{ env.PORT }}
  script_stop: true
  script: ssh -ohostkeyalgorithms=+ssh-dss user@20.x.x.x "echo Hello"

However, i need to pass The host key Algorithm to login.. May i ask how to pass the same ?

@arununzer Hi sorry for the late response. Your scenario is the following flow:

     +--------+       +----------+      +-----------+
     | Laptop | <-->  | Jumphost | <--> | FooServer |
     +--------+       +----------+      +-----------+

right?

Hello @appleboy , No jump hosts .....its from Github action runner (hosted in EKS) ...i need SSH directly to the instance using this :

ssh -ohostkeyalgorithms=+ssh-dss user@20.x.x.x "bash ./billing.sh"

@arununzer

pass environment variable to shell script

Try https://github.com/appleboy/ssh-action#pass-environment-variable-to-shell-script

@appleboy

can you please share as an Example keeping this ?

• name: Run SSH command
  uses: appleboy/ssh-action@master
  with:
  host: ${{ secrets.BILLING_HOST }}
  username: ${{ secrets.BILLING_USER }}
  password: ${{ secrets.BILLING_PASS }}
  port: 22
  use_insecure_cipher: true
  debug: true
  script: |
  echo "${{ steps.generatedpassword.outputs.pass }}"
  ssh -ohostkeyalgorithms=+ssh-dss a.krishnakumar@1x.x.x.x "bash ./billing.sh"

Like Where i should pass the hostkeyalgorithm ? As the Above is not working

[arununzer]

@appleboy Can You let me know how i can pass the hostkey algorithm for the Above example ?

[arununzer]

ignore this as it didnt work..

did a workaround and used it in this way directly

export SSH_OPTIONS='-o StrictHostKeyChecking=no -ohostkeyalgorithms=ssh-dss'
sshpass -p *** ssh $SSH_OPTIONS @ "touch arun.txt"
