We recently moved a web server running Fedora 2 and Plesk 8.2.1 to a virtual machine. Since then, qmail has been refusing to send messages to certain servers, complaining in the mail log that "TLS_connect_failed:_error:24064064:random_number_generator:SSLEAY_RAND_BYTES:PRNG_not_seeded". Evidently this is an OpenSSL problem related to the switch from actual to virtual hardware. Is there a way to change where OpenSSL is getting its random data from, or at least to tell qmail to fall back on non-secure protocols SSL/TLS doesn't work?
Within our co-located networking closet, we have control over two ranges of 254 addresses, e.g. 64.123.45.0/24 and 65.234.56.0/24. The problem is, if a host has only one IP address, or a block of addresses in only one range, it can't contact any of the addresses in the other subnet.
- All of our hosts use our hosting provider's respective gateway, e.g. 64.123.45.1 or 65.234.56.1
- A host on the 64.123.45.0/24 range can contact the 65.234.56.1 gateway and vice-versa
- Everything in our closet is connected to an HP ProCurve 2810 (a Layer 2-only switch), which connects through a Juniper NetScreen-25 firewall to the outside world
What can I do to enable communication between the two ranges? Is there some settings I can change, or do I need better networking equipment?
