Start your SSH as soon as you open your terminal so you don't have to keep entering your passphrase throughout that session. Enter this at the bottom of your .bashrc file
SSH_ENV=$HOME/.ssh/environment
# start the ssh-agent
function start_agent {
echo "Initializing new SSH agent..."
# spawn ssh-agent
/usr/bin/ssh-agent | sed 's/^echo/#echo/' > ${SSH_ENV}
echo succeeded
chmod 600 ${SSH_ENV}
. ${SSH_ENV} > /dev/null
/usr/bin/ssh-add
}
if [ -f "${SSH_ENV}" ]; then
. ${SSH_ENV} > /dev/null
ps -ef | grep ${SSH_AGENT_PID} | grep ssh-agent$ > /dev/null || {
start_agent;
}
else
start_agent;
