[pfsense]fixed warning open vpn cache password in

The issue is that I am disconnected from my OpenVPN server after exactly one hour, and I’m not sure what directive or choice is to blame. Is it possible that it’s a client issue? I’ve tried a variety of Windows operating systems and VPN clients. The Linux clients are functioning normally, with no interruptions.
Your authentication configuration appears to be the source of the problem. You’re using the /usr/share/openvpn/module/lib/openvpn-auth-pam.so login plugin, which requires the client to link with a correct username/password combination. This appears to be needed when rekeying, and your OpenVPN client appears to be unable to obtain the user name from stdin (ERROR: could not read Auth username from stdin).
The explanation why increasing reneg-sec in your server configuration does not help matters is that the parameter must be defined in both the server and client configurations in order to be effectively increased above the default of 3600 seconds (which happens to cause the one hour – disconnect you are seeing).

“Cannot load certificate register,” says an OpenVPN log entry. XXX.crt: error: 02001002:system library:fopen: XXX.crt: error: 02001002:system library:fopen: There isn’t a file or directory with that name: When using a TAP link, OpenVPN can show a series of these messages. error: 20074002:BIO routines:FILE CTRL:system lib: error:140AD002:SSL routines” Although a few of these messages are natural, if they appear for more than a few seconds and the link is never formed, try connecting with DNS/WINS set to “Set nameserver (alternate 1).”
You attempted to link to a VPN without first creating a configuration file. To access configuration and other files or details required to change the sample file, contact your network administrator or VPN service provider. See Having VPN Service for more information.
Changing the addresses of your local LAN is another choice. This is accomplished by altering the configuration of your router. For some routers, you specify the first three numbers of the LAN (for example, 192.168.77); for others, you specify the router’s address (e.g. 192.168.77.1).

Please understand that this is not a cause for concern. It is visible to everyone, so there is no issue with your device. The warning suggests that if anyone had access to your (virtual) memory, they might potentially steal your VPN password. Real, but if a hacker already has access to your RAM or page file, your VPN password should be the last thing on their mind.
When connecting to a server using *.ovpn files, simply add the line “auth-nocache” to the config file of the server you want to link to, and the alert will vanish. This is currently not possible with the HMA VPN client, but as previously mentioned, implementing this alternative does not boost your protection or close security leaks.
