comment How would you send syslog *securely* over the public Internet?
UDP syslog has certain advantages when it comes not causing outages if the destination goes down for longer periods. Not a too big deal with syslog-ng, but can be a nightmare in rsyslog. Encryption's value is nothing I want to question by saying that.

comment When RAID 10 is SLOWER than RAID 1, why?
for the record, it's extremely uncommon to have a DBA that is smart enough to just differently store the different redo/archive logs on really different spindles. in that case it'll be as he described and you experienced. i've had dba's INSIST everything goes to a different filesystem on the same disk, but I've only encountered one like yours, out of maybe 30 i worked with. Consider yourself lucky.

comment Hiding hosts in Nagios
I dont see why this was downvoted, while hidden hostgroups are NOT available in each nagios version or clone it's one of the most elegant ways to do this.

comment Does two pfsense + CARP necessarily require two WAN IP?
Any VRRP / HSRP setup I've seen so far has not used IPs from the attached subnet for the cluster interfaces themselves.

comment Why should we purchase a dedicated load balancer when the firewall can do it?
While I think that you're right that failover is enough for your case, and I've seen nice "middle ground" as load balancer pools in Juniper firewalls or even pfSense... I still think you're wrong with one thing: the words "such a simple task". Don't assume anything is simple unless you've already mastered it. Load balancing is part of highly redundant infrastructures and we can aim to get it simple, but basically - do that for a job and one day you get the ticket that you spend days on and never really figure because it's some twisted tcp bug. Nothing is simple if you look closely.

comment How to generate netflow data in linux
This isn't freebsd where such software can be developed against already in place kernel features like netgraph. Hardly any way to do this without a custom module. The good thing (and that's why i'm commenting) is that the sources are now on github and it also has dkms support now. Looks pretty good. github.com/aabc/ipt-netflow

Thank you that's simple and elegant. I did not come up with that idea, as much as I tried ;)
