Sorry, error in my report. The RH8 servers are running ldirectord1.90 and
1.90 runs correctly on EL3. I guess the problem lies in the changes in 1.91.
If I can help in debugging please mail me.
Thanks,
Phil

Subject: Ldirectord Redhat EL3 SSL checking problem
Hi,
I had a pair of ultramonkey loadbalancers running Redhat 8. I rebuilt the
secondary with Redhat EL3 Update 3, installed the UM packages and
ldirectord1.92 and copied over the old ldirectord config. The EL3 server is
now failing to make the SSL tests that the RH8 box is still doing.
The webservers (Redhat9 Apache/2.0.40 and IIS4) being SSL polled by EL3 are
logging successful requests: [27/Oct/2004:15:33:34 +0100] <EL3 ultramonkey
IP> TLSv1 DHE-RSA-AES256-SHA "GET /hello.html HTTP/1.0" 5
The only difference I can see between the ultramonkey servers performance
that is that the RH8 server is defaulting to a different cipher:
EDH-RSA-DES-CBC3-SHA. However, I know that EL3's cipher (DHE-RSA-AES256-SHA)
is working correctly because OpenSSL's s_client uses it successfully against
the same server.
I've had fun with Redhat and SSL before, but I'm really not sure what's
going wrong here. I suspect the penultimate error log line below holds the
key, though I havn't been able to fathom it.
Below is ldirectord's relevant config and a debug log. Any ideas or pointers
gratefully received.
Thanks,
Phil
