Again there was a need to fix frickelsoftware. In that case i needed a permanent vpn connection via the fortigate vpn client . Problem is, that the tunnel disconnects after some time but the client does not exists and that input cannot simply piped into the executable.
I wrote an Expect script which works work around both issues:
#!/usr/bin/expect -f # cd into the 64 bit folder of the client # usage: efort.exp spawn ./forticlientsslvpn_cli --server <VPNIP>:<VPNPORT> --vpnuser <VPNUSER> 2>&1 log_user 0 send_user "Logging in\n" expect "Password for VPN:" send "<VPNPASSWORD>\n" # i needed ths for 'certificate error' expect "Would you like to connect to this server" send "Y\n" send_user "Beginning to connect\n" expect "STATUS::Tunnel running" send_user "Tunnel running!\n" # this is how long the next expect waits for pattern match, in seconds set timeout 90001 expect "STATUS::Tunnel closed" send_user "Tunnel closed!\n" send_user "Dying\n" close exit
At the end, enterprise-loop the script and we are done!
#!/bin/sh cd "$(dirname "$(readlink -f "$0")")" while sleep 1;do expect efort.exp echo "Restarting forticlient !" done
