# Dropbear Connect Script (DBC) - Developed by acidvegas (https://git.acid.vegas/void)
|
|
|
|
# Dropbear config must be stored in pass in the following format:
|
|
# NAME USER HOST PORT JUMP
|
|
#
|
|
# JUMP is optional and can be used to specify a host that should use your jump host.
|
|
# If JUMP is set to x, the script will use the jump host to connect to the end host.
|
|
# There should only be one jump host in the config file and it should be named 'jump'.
|
|
#
|
|
# Example:
|
|
# jump acidvegas 68.192.37.5 5902
|
|
# hatebox acidvegas 100.151.45.10 2023 x
|
|
# aws admin 45.16.150.203 22
|
|
#
|
|
# Useful commands:
|
|
# Git usage : git config core.sshCommand "dbclient -i ~/.ssh/key"
|
|
# Generate private key : dropbearkey -t ed25519 -f ~/.dropbear/key
|
|
# Get public key : dropbearkey -y -f ~/.dropbear/key | head -n 2 | tail -n 1
