comment Create a /16 (255.255.0.0) local network
@TomO'Connor I'm not sure this practical question is answered directly in the canonical answer about IPv4 subnets.

comment Can VPNs reduce latency?
@HopelessN00b I disagree. It's absolutely and completely a request for expert answers related to managing computer systems in a professional capacity.

comment Can VPNs reduce latency?
@HopelessN00b I'm thinking about offering a very latency sensitive gaming service. I need to know what can be done to improve the experience and what the limits are and where are they. This is totally on topic from that POV, IMO.

For admins: this is a similar question, but different enough to warrant different answers. @3molo: I also wish you could.

@michael_n Don't all VPNs use some kind of encryption? That's what I meant. You can of course send/receive encrypted data and not partake in a VPN.

comment How do I find if there is a rogue DHCP server on my Network?
Depends on the amount of people you are serving. You can disrupt the service for a couple of minutes in most cases and nobody will notice, especially in the middle of the day when most people have their lease already.

Not sure, you should probably now open a followup question on how to tune / debug SYN queue issues

comment Some Apache requests are slow, most complete instantly
I would personally try to use a big number, like 16 or 64K to make sure it's not an attack (on an attack virtually every limit would get surpassed), and if it's not an attack, I would gradually diminish the queue size until a good small value is found)

comment SYN flooding still a threat to servers?
I think that enabling them when needed is better than enabling them by default. They might be spec compliant, but they also reduce the amount of the spec you can use...

comment Some Apache requests are slow, most complete instantly
That message means your SYN queue gets repeatedly full. That may be due to legitimate requests or not. If the requests are legitimate, you can increase the size of the queue with tcp_max_syn_backlog. See linuxinsight.com/proc_sys_net_ipv4_tcp_syncookies.html and redhat.com/archives/rhl-devel-list/2005-January/msg00447.html

Cached set of credentials was it. Deleted them and voilà.

comment \\NAME\share gets permission denied whereas \\IP\share doesn't
Edited the question with more info I thought about after reading your answer. But, how do I know if Windows is using a cached set of credentials? I've already tried rebooting.

comment RAID 5 with big SATA disks. Do or don't?
Is a 500GB enterprise class HD safe enough for RAID5? (that's the other alternative for me)

@Chopper3 That's a fine argument. Let's see if I can make it fly.

Are the disks that advertise "works 24/7" really trustworthy? For example seagate.com/www/en-us/products/consumer_electronics/sv35_series

comment RAID 5 with big SATA disks. Do or don't?
@Evan: That's all well and cool, but the cost is too high, especially when (as is my case) performance is non critical. So I guess RAID 6 it should be

in the last part, did you mean ip route add default via 10.0.1.1 metric 1000?
