did you have any success disabling SSLv3? I would like to disable any
old ciphers and turn on Forward Secrecy. Do you have experience with
this and perdition?

AFAIK, this enables STARTTLS in the port instead of starting a
purely encrypted connection.
nc -vv imapproxy01i 993
Connection to imapproxy01i 993 port [tcp/imaps] succeeded!
* OK [CAPABILITY IMAP4rev1 SASL-IR SORT THREAD=REFERENCES
* MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN NAMESPACE
* LOGIN-REFERRALS STARTTLS LOGINDISABLED] perdition ready on
* imapproxy01i 00028de7
I haven't tested but I think this may not change the list of
accepted cyphers. After reading the manual and some messages in
the list, it seems that all references to TLS in the
configuration are aiming at STARTTLS and the only way to change
the valid ciphers is with *ssl_listen_ciphers* and
*ssl_outgoing_ciphers*. Am I mistaken?

i have a system that has both ipv4 and ipv6 addresses configured in dns,
but if i use that name as the bind address for perdition, it seems to
only bind to the v6 version. for now i have hacked things by using
separate names, but i'd like to have a single name for both v4 and v6.
am i missing some obvious way to force perdition to listen to both?
I have following problem:
Host Ubuntu 14.04 desktop
VMs Ubuntu 14.04 desktop/server edition
I have several websites running on VMs, each with its own domain/subdomain and internal IP address. But I have only one Fixed IP/External IP.
Could Perdition help me out? If YES please advise where can I find relevant document of its setup?
All VMs are Apache server running WordPress. My problem is I have only ONE Fixed IP. I can create many internal IPs on router.
Several years ago I made use of Perdition to setup several mail servers on VMs but served with only ONE Fixed IP. It worked seamlessly. All emails were delivered to their own servers. Maybe I can dig up the respective documents on my database. But I have no idea whether it also work on web-server?
