comment DELL switch CAM table don't show MAC from different network
Caution: Do not enable portfast on any port that might get connected to anything other than an end station. (Unless you know exactly what you're doing.)

comment DSL :: Connection top speed is ok, but acceleration is low
The odd thing is, when I trace that same path (but in the other direction), I get normal pings. I see about 5ms on that hop.

comment Determine performance of disk cache in Linux 2.6.32+
@GoldenNewby: The vast majority of books are unpopular. But having so many unpopular books makes a great bookstore. But you are correct that Linux could, in principle, keep sufficient information to simulate the affects of different cache sizes. However, that's really much more complicated than it sounds. (Think about the bookstore trying to figure out which books it would have decided to carry and not carry in the past.)

comment WWW record in DNS (type CNAME) pointing to a site is recommended?
Working together. If you just make www.somedomain.com a CNAME for, say, www.microsoft.com, it may or may not work.

Or you'd have to be coordinating with website.com. Because of Host headers, HTTP usually won't "just work" if you redirect your DNS to point to a stranger's server.

comment VLAN routing issue
Because servers typically have such filtering enabled by default and switches and routers typically have such filtering disabled by default, if they're even capable of it.

What do you mean by "spare" memory?

comment Will anycast helps me in my case and how to implement it?
Why do you want a single IP address rather than single DNS name?

It is much more likely the server is doing it.

comment Timekeeping between various Windows computers on network (but not all)
It's really hard to figure out what you're asking. What kind of problems are you concerned about? What do you think might be bad about this? You've stated the textbook, simple/obvious way to get the job done.

comment Why is connecting to a web server listening on an IPv6 link-local address unreliable / How is IPv6 neighbor discovery expected to work?
Don't use link-local addresses for this purpose. That's not what they're for.

comment VLAN routing issue
It's very unlikely that it's the switch filtering it.

comment does scp affect performance
scp has a limit option to limit the bandwidth used. It also winds up limiting the CPU and disk usage too, but you can use nice/ionice and whatever other tools your platform offers to minimize its impact.

comment multiple subnets on the same cisco switch port
More likely, they just put each IP (other than the first) in its own subnet and routed them to the host as /32s. You can also put multiple subnets in the same VLAN. I'm not sure why you think that won't work in your environment.

comment multiple subnets on the same cisco switch port
@EugeneM: It doesn't require bonding, it just requires trunking. Providers add additional IPs without requiring you to reconfigure your server because the IPs are in the same subnet.

comment multiple subnets on the same cisco switch port
"Trunking" is practically defined as "having multiple VLANs on the same port". Why don't you trunk to the server?
