Re: [Radiusplugin-users] OpenVPN crashes when radius server is unreachable (v2.0c)

[Jan Mulders]

They do not show any errors at the time when openvpn freezes, but an 'auth failed' message is shown further up.

Here is a selected portion of the logs, showing the initial auth failure, the subsequent flood of tls failures,  the flood of clients trying to connect again, another auth failure, and the subsequent lockup point. (look for the ..., they seperate the sections).

Logfile removed for privacy reasons on public mailing list post.

Do your openvpn logs report any errors?

Hello everyone,

I'm having some problems with an existing large installation of openvpn+radiusplugin.

Whenever the RADIUS server times out in responding to a request (it can sometimes take up to 3-4 seconds to reply), the entire OpenVPN process freezes and requires a kill -9 to terminate.

Here is what my config file looks like:

NAS-Identifier=server4
Service-Type=5
Framed-Protocol=1
NAS-Port-Type=5
NAS-IP-Address=11.11.11.11
OpenVPNConfig=/etc/openvpn/server.conf
#vsascript=/etc/openvpn/vsascript.pl
subnet=255.255.255.0
server
{
       acctport=1813
       authport=1812
       name=22.22.22.22
       retry=10
       wait=4
       sharedsecret=secret
}

Can anyone help me work out why this is happening, and how to stop it?

Thanks,

Jan
