[Xymon] sslcert question

Thu Apr 14 02:00:18 CEST 2011

Nope, I'm not using that sslcert feature --- so maybe I should stay quiet on this one :)

I think xymonnet does the checking directly. Henrik does have a
"contest" program in the xymonnet src directory, I assume for
troubleshooting, but it doesn't return the ssl stuff, just the returned
header.

The other system is RHEL 4.6 which is running the websphere - I ran the
openssl and got 45 ciphers, so what xymonnet returns is correct for what
is configured in IHS. IBM don't use mod_ssl, they wrote their own thing.
In the IHS config, you can specify which ciphers to use, similar to the
CipherSuite statement in apache.

Do you use this sslcert feature, are you having this problem?
