    DNS Root domain forwarder

    I believe ( I haven't done this in a while) but you can declare the NS servers for the domain .xyz seeded in your root cache. The root cache is just a hint (for .) so your would add this to the root cache. xyz. 3600000 NS nameofxyzdnserver.xyz...

    Bind9 wildcard to redirect ALL IP's

    Using DNS for this is a poor choice. A port forward can do it trivially for port 80.

    Virtual Host issue

    You can always bind that one to a different IP and host it on the same server, whether or not if it is virtual hosting.

    failed to copy 1 huge file

    So we know the reading is from usb device. What I am unclear is where are you writing. Use the "df directory_that_you_are_writing" to figure out what physical device your are writing on. Is it NFS or an ext3 device. If ext3, what is the block size.

    Concurrent Connection Limits, protection from surpassing, planning for

    All the tuning parameters are on the server end, which means if he is hosted he probably cannot change any of them. We typically twiddle MaxClients, ServerLimit, MaxRequestsPerChild, ListenBackLog, MaxSpareServers, MinSpareServers in Apache, and a host of OS related stuf like NumProcs, file...

    failed to copy 1 huge file

    Yeah, I am still not sure if you are writing on the NAS or hard disk. Do the df thing to make absolutely sure you which physical device you are writing. You said "NAS" attached, is this an automount? If you did the "wc -l" that eliminates the usb because that reads all bytes.

    failed to copy 1 huge file

    what is the failure? Is it logging in /var/log/messages anything? Is it a read (I would run "wc -l THEUSBFILE". This is a simple test, wc needs to read all the bytes to calculate things. So this verifies the reading. But first, in the directory you are writing, go "df -k ." to verify you have...

    DNS forwarding doubt

    What flavor is the external DNS server? Typically one can solve this with Split Horizon DNS such that the external has a different "view" of the internal. I don't believe windows DNS has split horizon, however.

    DNS service or server with this feature??

    I haven't done it in a while, but wildcards on bind work on A records. So you would specify the records for dean and myweb. dean in A 1.2.3.4 myweb in a 2.3.4.5 * in A 6.7.8.9 ;for the rest. This also works for CNAMES. www in a 6.7.8.9 * IN CNAME www.alvazan.com. BTW, @ means the domain...

    Listening for SMTP (MS Exchange) on redundant routers

    The smtp/mta protocol already handles this; it tries both MX records if they are weighted the same. So as long as both can route mail, advertise both at the same MX precedence. If one goes down, then the other will be tried. If you prefer one over the other, make the preferred one at a lower...

    Virtual Host configuration

    I stand corrected. Yes, you probably can integrate virtual host with multiple proxies. Here is the first google doc that has an example: http://confluence.atlassian.com/display/DOC/Using+Apache+with+virtual+hosts+and+mod_proxy you see it has a name based virtual host, and uses the proxy...
