The SSH server performs a reverse DNS lookup on the connecting IP address. If there is no reverse DNS record for that IP address or the name server is foobar'ed, the SSH server will wait until timeout on the DNS lookup, then prompt for password and log the connection by IP. I usually put UseDNS no in my /etc/ssh/sshd_config to avoid this problem. If I need to know the DNS name associated with something in the log, I can always look it up later.

If the extender is a 802.11g device, I'd expect it to produce the same throughput as the original source. When dealing with a half-duplex broadcast network like this, it's helpful to think of bandwidth in terms of time. A range extender has to take the time to listen to a packet, then it has to take the same amount of time to transmit that packet. (In a half-duplex network you can't talk and listen at the same time.) So it takes twice as much time to send a packet through a range extender as it does to send it direct. This halves the available bandwidth. Likewise, copying from a wireless device to another wireless device, through an access point, gives you half the bandwidth you'd get going from a wireless device to a wired device; the access point has to listen to each packet, then resend it. This is also why having 802.11b devices on an 802.11b/g network tends to lower throughput dramatically; the b packets take up more airtime, leaving less bandwidth available. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

It's actually pretty hard to get the full bandwidth that 802.11g promises. In particular, there can't be any other networks on the same channel, or on overlapping channels. (802.11 signals are three channels wide, so networks on adjacent channels affect yours.) A scanning tool such as Kismet can be helpful in picking a clear channel. If you have lots of close neighbors it may be impossible to find one. In that case using 802.11a, which runs on a different frequency band, may be an option. (Assuming the 5 GHz band is legal to use in your country.) You can't have any 802.11b devices on the network if you want to get full speed. They greatly slow things down just by virtue of the 802.11b packets taking longer to transmit, thus tying up the network for longer. Other devices that use the 2.4 GHz band can also cause problems for 802.11g. These include microwave ovens and some wireless phones.

Also, there is a job priority, so that important Pending jobs jump to the front of the line, and less important jobs fall to the rear. Just like with at, jobs can be scheduled to run at various times. Of course, if the execute slots are all full at a job's run time, it goes not to Executing but to Holding state. This sounds pretty similar to what Condor does for clusters: http://www.cs.wisc.edu/condor/ It queues up jobs and executes them on available CPUs, either locally or on other systems in the cluster.

There are some exceptions; for example, if a previous delivery to the same server failed, Exim won't try any messages until the retry timeout has expired, so those messages will stay in the queue for a while. default/exim4: 2) does stuff leave the que ONLY when it is 'run' ? if yes, then by default, email will only leave the que every 30 minutes [minimum] (QUEUEINTERVAL='30m' is the installed setting) So If this is correct, then I, personally, want Email leaving 'immediately'. So is there any reason I should NOT set queueinterval=1m ?? As I said, if the server is up email will be sent immediately.

The click was meant to simulate the action of the typewriter ball smacking the paper for those of us who learned how to type on typewriters. Right, that's the real trick. The click is supposed to cue your brain to stop increasing pressure on that key and start pressing the next one. All good keyboards have some kind of tactile feedback before the key hits its stop; the IBM clicky keyboards have a sharper and more defined version of this than most. I noticed the importance of this pretty early when I realized how much faster I could type on an IBM keyboard than on a Apple or Commodore. The keyboards on the latter two machines had no tactile feedback -- the keys just bottomed out.

Incorrect technique is far more risky than using a clicky keyboard. Uh huh. I'd go farther and say that those wrist rests they sell for desktop keyboards are snake oil. Actually, they're worse than snake oil. They actually encourage carpel tunnel syndrome, by tempting people to place their wrists at a sharp angle.
