ssl: unsafe legacy renegotiation

[sashk]

Hello,

I have a very old device, which I cannot replace, but would like to monitor. It uses TLSv1 for SSL and I’d like to check that it is online by querying its https port. I have following check:

check host cable_modem with address 192.168.1.1

if failed port 443 protocol https status = 200 with ssl options {version: TLSV1, verify: disable} for 2 cycles then alert

But when monit checks, it reports following error:

failed protocol test [HTTP] at [192.168.1.1]:443 [TCP/IP TLS] -- SSL connection error: error:0A000152:SSL routines::unsafe legacy renegotiation disabled

Is there a way to allow unsafe legacy renegotiation only for this particular check? It seems re-configuring OpenSSL it is possible to do systemwide, but I would like to avoid doing so.

Thanks in advance
