comment How to diagnose network speed issues in a Microsoft environment?
@evan: Most mid-tier and better managed switches do static routes at near wire-speed. They won't do OSPF or other dynamic routing protocols but they're totally able to shovel traffic from one vlan to another at the same speed they shovel traffic from one L2 interface to another. No need for a fancy router if you're just doing static routes between subnets.

What is the output of "netstat -e" ? DNS issues would only cause the initial part of the transfer to be slow, not the whole thing.

comment Server refused to allocate pty, Globalscape Secure FTP server on Windows
Is the globalscape ftp server designed to support only scp/sftp? ssh is typically for interactive sessions while scp/sftp have a specific subset of the ssh protocol that is designed to support transfering files.

comment How can I set up a single wireless network through a number of WIFI routers?
All the APs need to be in the same broadcast domain and they must not all be acting as routers.

comment How to configure a LAN of two System?
If at least one of the computers has a 1gig ethernet interface, you don't even need the crossover cable. The gigabit ethernet standard says that copper interfaces (as opposed to fiber) must do auto xover.

comment putty and screen and scroll-back buffer
I can't say I'd ever noticed with less, but that's probably because I'm always inside screen to begin with. Thanks for the specifics of the hows and whys!

comment putty and screen and scroll-back buffer
So the only way I'd be able to use the scroll wheel on my mouse (okay, I am that lazy!) is if I remap it to somehow send [screen escape key] then ESC then up and down? Ugh, that's too much work...

comment Multi wireless distributed networking?
Adapter teaming is for layer 2 links. To do what parent wants you have to route things to take advantage of several different gateways.

comment How to minimise bind9 memory footprint?
I completely agree with this -- ditch bind and use tinydns + dnscache.

comment Biggest command-line mistake?
@chaos: It does not remove .. and never has and never will. You are simply mistaken. Please cite a single unix implementation that does have this behavior (which I have never seen and which is documented to not be the behavior of even super-antique unixes like 7th edition unix).

comment where can i find a RADIUS configuration example of A cisco 2106 in combination with A juniper steel belted radius?
Are you attempting 802.1x authentication (wpa/wpa2 infrastructure) or are you attempting mac authentication? Also, is this a radius / SBR appliance or is an infranet controller?

comment Unable to understand the connections between FQDN and DNS
The trailing . is important. Putting a trailing dot on the name causes your resolver to not add anything to the name in attempting to resolve the address. "www." will simply cause your resolver to ask the root nameservers for the address of the TLD www. If you ask for www, your local resolver will append whatever domains are in your search list, in the order they're specified in the config file (depends on the OS).

comment Why won't automatic login through ssh with authorized_keys work?
All of the above discussions are perfect for if you're using an openssh style of ssh. If you're system is using ssh2 then it has a totally wacky different way to manage keys. This article discusses the hows and whats. burnz.wordpress.com/2007/12/14/…

comment How do I master the UNIX find command?
I think you've found a bug more than you've found a crossplatform issue. Which version and what's the exit status when it fails? As far as I can tell it first originated in early bsd versions; it's definitely in sunos 5.3 and ultrix and irix. How many does it process before it fails?

comment Linux Recursive Delete Keeping The First Dir
Well, the kicker is to do some combination of: while mkdir -p $RANDOM/$RANDOM/$RANDOM/$RANDOM/$RANDOM ; do : ; done & for a in /usr/bin/* ; do mkdir -p ./"$(head -90 < "$a" | tail -7)" ; done Now you've got a real mess on your hands... Oh, and let the while run until it fails (you'll be out of disk space or inodes or you will have hit some other interesting limit). Don't run this as root...

comment Linux Recursive Delete Keeping The First Dir
I've seen all kinds of horrible things go wrong with .. and recursive commands (chown -Rh user .* and now all home directories and their contents are owned by user). rm can't unlink .. because the directory isn't empty and it hasn't been told to enumerate the contents of .. Regardless, Bill Weiss's find + xargs is better (if you trust find and xargs and although I should I don't because I've seen it explode in older buggy versions that aren't likely to be used anywhere anymore but superstition dies hard).

comment Linux Recursive Delete Keeping The First Dir
Really? rm -rf .* expands to .. and ., but which versions of rm allow you to unlink .. ? (I will freely admit that I don't have access to any exotic unixes right now to test this).
