You can provide two arguments on the command line, the first one is the hostname that will +accept passwordless login and the second one is the username on that machine. + +If the second argument is ommited, the username will default to the username on the client machine and if both arguments are omitted, they will be asked interactively. + + +evision: _sha1_ + +Build date: |today| + diff --git a/utils/infra_setup/passwordless_SSH/set_passwordless_ssh.sh b/utils/infra_setup/passwordless_SSH/set_passwordless_ssh.sh new file mode 100755 index 00000000..cbca6b20 --- /dev/null +++ b/utils/infra_setup/passwordless_SSH/set_passwordless_ssh.sh @@ -0,0 +1,52 @@ +#! /bin/bash + +#this script is copied from https://github.com/guioconnor/Passwordless-SSH. +#the Bottlenecks project needs to set the machines login each other passwordless, this script is appropriate. + +filename="id_rsa" +path="$HOME/.ssh" + +if [ $1 ] +then + hostname=$1 + if [ $2 ] + then + username=$2 + else + username="$USER" + fi +else + # Read the host and username to store public key (the host/username accepting passwordless ssh from this computer) + echo "What host you want to grant passwordless SSH from this computer?" + read hostname + echo "What is your username on $hostname?
