Expect script to connect to an AnyConnect VPN server on OSX using only oathtool and openconnect (not the Cisco AnyConnect client)

vpn.expect

!/usr/bin/expect -f
set timeout 30
log_user 0
 
puts stderr "Generating OTP"
spawn oathtool --totp YOUR_SECRET_KEY_HERE
expect -re \\d+
set otp $expect_out(0,string)

puts stderr "Connecting to VPN server $server"
spawn env SPLIT_DNS=YOUR_SPLIT_DNS_DOMAINS_HERE openconnect --script ./vpnc-script https://YOUR_SERVER_HERE --cafile=cacert.pem
expect "GROUP:"
send "YOUR_GROUP_HERE\n"
expect "Username:"
send "YOUR_USERNAME_HERE\n"
expect "Password:"
send "YOUR_PASSWORD_HERE\n"
expect "Password:"
send "$otp\n"
 
interact

thanks! this script was super handy!
