Hi Lou
Your query is a bit unspecific (there is a lot of information missing
such as OS to be used or a reason [stats, monitoring, ...]) but maybe
you can use this approach:
(echo "" | openssl s_client -connect <hostname>:<portnumber> -showcerts
| openssl x509 -text | egrep -i "not (before|after)") 2>/dev/null
I use it for monitoring. It works with all ssl wraped protocols (ie.
smtps ftps, imaps pop3s). It does not work with other encrypted services
such as ssh or sftp.
Regards
Martin
