Most major browsers will display an error or block access entirely to self-signed certificate sites, correct. If your site's users are willing and able to import your CA they would then automatically trust your certificates.

comment Is it possible to pass /dev/urandom through from the host to a qemu/kvm guest?
I can see a way to do what you are asking but it seems terribly kludgy: cron script pulls a buffers worth of data on host OS into a file (cat), copy it into a file which has a filesystem (dd mke2fs cp), which is loop mounted and shared into kvm to its guest ... yuck.

comment Does changing web hosts (changing a domain's nameservers) affect the private nameservers / glue records created under that domain?
"Now, we're thinking of switching web hosts (not domain registrar just the host) which means I have to change mydomain_a.com's nameservers to the new host." I at least don't understand how B requires A here?

comment Is it possible to migrate OS X Server user passwords to Linux?
In general securely stored password (those stored with a strong salted hash, etc) can't be migrated any more than they can be easily cracked. In almost all cases of migrations such as these mass password resets are inevitable.

comment Possible rooted debian (wheezy) server?
@debianuser That really sounds like an IP conflict or some other network malfeasance. I'm not aware of any DRAC software, just the firmware for the cards. Agree on odd :)

comment Possible rooted debian (wheezy) server?
DRAC (Dell Remote Access Controller) is a expansion card for Dell servers that presents a web interface and not a software module so it is probably not installed on your SuperMicro :D. As above that part of your question sounds like a network problem (arp or DNS cache?). Without a little more information about your system it maybe hard to suggest how you should proceed, but you can certainly run a rootkit detection program such as in serverfault.com/questions/124151/…

comment Firewall blocking some strange communications from source-port 22 to over-seas ip addresses. Should I be concerned?
You may want to determine if there is an open SSH process on your server at the time of the log message and trace what started that process. You can start by using netstat or lsof to find the open ports/sockets on your server. Without additional detail bout your firewall, port forward, network setup it may be hard to tell more.
