Actually, in some old *nixes, that absolutely was NOT the case. If the shell in/etc/passwd returned a non-zero value (note that/bin/false always returns 1), 'login' would drop them immediately to an emergency shell for 'maintenance'- usually a statically-linked Bourne shell, and sometimes a setuid root version!
Not that this behavious persists today, but just to be safe, use/bin/true instead;).
Unfortunately, the NIC can still introduce errors and whatnot onto the segment... Also, don't forget that not all traffic on an ethernet segment is IP!
The biggest problems are:
A switch can mangle the packets a little before they're port-mirrored
How exactly DOES one monitor >100mbit full-duplex traffic using only a single 100mbit port:) ? (dropped packets are a significant reality on a busy network)
'Course, what you REALLY need is a good, *electrically* transparent impedance matching tap, like one of these.

Dolly Parton is buying up three grocery store chains: Big Star, Piggly Wiggly, and Harris Teeter. The new conglomerate will be called Big Wiggly Teeters.

Nothing that I know of, but that's an awesome idea. It would probably require a new extension (well, codec).
The way we've solved that problem to date is with VPNs, which incidentally solve other problems, such as QOS.
They won't directly teach you how to be a good admin, but they have a lot to offer:
All good admins had good mentors. A good college or university is the place to find them.
While at college, you can choose a less challenging curriculum and still do some admin work on the side.
At the end of your college career, you'll already have 2 or 3 years of experience under your belt.
Stick with Unix- don't waste time with NT or Win2K. Then windows admin market has two dubious issues: A. The market is saturated, making them a $28k/year commodity; and B. It's much harder to distinguish yourself in the industry in a saturated market.
Beer, women, and community. Those reasons are enough to make me want to go back almost every day:) .
I can seriously vouch for #'s 1, 2, and 5. By the time I left school, I had 2 years of sysadmin under my belt, and excellent skills because of a good mentor. I was even able to take my time and choose between a couple gigs > $70k.
I am in the process of moving, and for the potential of ditching HellSouth, considered Vonage. I had several issues with them:
Their notion of "regional" calling is fairly "interesting" (read: vague!)- it's not clear what constitutes a local call (except for their list of area codes, none of which seem to correspond to geographical locations...)
When people geographically near to me call me, do they pay long distance tolls? (it sure seems that way, since you are assigned a "Vonage" area code...)
They require a 12-month contract
No 911 service...
[3] wouldn't be so bad, except for [1] and [2].
I'm certainly willing to forgive [4] considering availability of my cell phone.
I would love to hear any reports from current customers...

Summary: Neither Intel or Compaq could/would help me, even discouraged me by telling me it couldn't be done. But, with a nice set of tools from these guys, I got it to work, and was even able to contribute to the project so that this device would be supported in the future.
Oh yeah. I also CC'ed Compaq and Intel's technical support;).
By the way, the builtin eepro100 was supported well by rh7.2's stock kernel, FYI (proof that integrators and distro maintainers are valuable methinks).

How are they going to build 106 cpu boxes with opterons?
Maybe somebody more familiar with the architecture can chime in here...?
You must be the proud administrator of a Solaris box running Solstice DiskSuite.
Or iPlanet/ONE- I can't tell from your post.
Hey man, $30 is alot of money for a paperweight!
If a full-blown 64-bit machine is a paperweight, what does that make your 32-bit peecee?
It really is much more secure.

A CPU that only runs half as fast as you expect. Wouldn't that be a Cyrix or an AMD k5?
Or a Pentium4?

What cookbook would be complete without a great chicken wing recipe?

"A fool and his money are soon parted."
Nice...
OT: WTF with no manpage for ntptrace (Redhat 7.2)? or info?
Who sells them in the US?
We (HCS Systems) sell them, and we're in the US (Raleigh, NC). Shoot me an email and I'll hook you up.

Check this out for another linux-based VoIP, standards-compliant (both SIP *and* H323) phone.
It's been out for quite awhile, over a year. My company is a reseller. They're cheap (~ $199 each) and they rock.
Sun has had this for awhile. Well, it's not as easy as cabling up boxes- but the architecture is similar, if not better.
Check out the Ultra Port Architecture. Basically a meta-bus that you can put CPUs, memory, and other buses (PCI, SBUS, etc) on.
It has always been up.

It's been said before and it bears repeating...
If it can be done, chances are that someone has been doing it for a long time.
This info sounds about 23 days late to me.

I just got it working.
Check here to see how.
This is because RPM can't do something like "a.rpm needs library X, let's see if any of the other RPM's in this directory have library X in them.
No it isn't, it's because you don't understand shell metacharacters. Do this instead:
ls *.rpm |xargs rpm -Uvh
A: There would be a current flow.
Was that the human or the kzin that asked that question?
