Iperf helps you run tests that measure maximum TCP and UDP bandwidth performance. It allows the tuning of various parameters and UDP characteristics reporting bandwidth, delay jitter, datagram loss: <a href="http://openmaniak.com/iperf.php" rel="noreferrer">http://openmaniak.com/iperf.php</a>

,And

<a href="http://www.bitwizard.nl/mtr/" rel="noreferrer"><h1>MTR</h1></a>

MTR (My Trace Route) is also a pretty good tool. It combines the functionality of the 'traceroute' and 'ping' programs in a single network diagnostic tool. Like traceroute except it gives more network quality and network diagnostic info. Leave running to get real time stats. Reports best and worst round trip times in milliseconds... It shows latency, jitter (average/best/worst): <a href="http://www.bitwizard.nl/mtr/" rel="noreferrer">http://www.bitwizard.nl/mtr/</a>

A magentized paperclip on a string. I dropped a screw in a full rack once. It was w-a-y down there. I had a strong magnet stuck to my desk but it didn't have any way to attach a string to it. So I found a thicker paperclip and magnetized it after tying some pull-string to it. I g-e-n-t-l-y fed it down the left side of the rack in the space between the server rails and the cabinet door. It took some poking, but it found the screw I needed. It took a few tries before I could pull it all the way back to the top without dropping it again.

Delicate work. At the time I was swearing vociferously that I clearly hadn't played enough 'Operation' as a kid.

Although all SysInterals tools are great, the tools which helped me the most, were the monitoring tools:

Here's my list of things I didn't see mentioned yet:

sticky stuff (like wall tack or putty) to pick up little bits in that fall into tight spots (little screws on motherboards)

non-oily lube (like teflon bike chain lube) for tight or frozen bolts on racked gear (esp. great for tight-back-of-rack situations where there's not much room to get good leverage)

strong knife, v. stiff putty knife, or very thin-tipped prybar for popping the head off stripped bolts. Drills work OK too but there's the vibrations and the metal shavings all over.

locking vice grips including small &amp; needle-nosed. In some cases, almost as good as an extra set of hands.

velcro strapping not just permanent cable management but hold things out of the way in packed racks w/o creating tangles or rats' nests.

slim-edge rack tool for popping the rack nuts in and out. I keep several in my bag "just in case"...they are commonly included with new rack-mount hardware but not always and they rarely are handy when you have to move something months or years later. Saves me a lot of ripped up fingers. They are also often just right for depressing the lock-clip on a tight network cable (esp. one with a boot) or a lock-clipped fibre patch for those of us with stubby or snausage fingers.

another use for a cellphone: some (easy) way to light up the screen as a quick flashflight for checking stuff out in the backs of cabinets

Back in my desktop days, I had kept a handful of CMOS batteries in my bag. This was esp. helpful when dealing with labs and offices where the PCs were 2+ years old and resolved many "head scratchers" in short order.

I once used office chairs in place of one of the fancy scissor-jack devices Chopper3 mentioned. I needed to relocate the UPS's in a rack, I do not know why they were half way up in a wheeled rack, but they were. I'd scheduled the maintenence window on a Sunday. My helper had a family emergency, and could not make it. I had my 9 year old duaghter with me. I could not manhandle the UPS to the ground by my self, and she wasn't strong enough. So I pulled the UPS out as far as I could on the rails, but a chair under it, and had her hold the chair while I lowered the UPS on to the chair. After resting and re-gripping, I lifted the UPS, and she pulled the chair out, so I could lower it the rest of the way down onto a set of blocks I'd brought to help hold the bottom UPS at the right height for the bottom of the rack. Then the remaining UPS's when onto the stack so they where roughly at the right heights as well.

I try not to use too many "nonstandard" tools. That is, tools that aren't easily available between operating systems or out of a particular distribution's software repository. I work on a Macbook, and I do testing on a variety of different Linux/Unix platforms. 

That said, I like <a href="http://github.com/opscode/ohai" rel="nofollow noreferrer">ohai</a>(1). It is the node data collection tool used by Chef. It outputs data in JSON, so it can be manipulated with a variety of JSON parsing libraries. Since I work on Chef :-), it's a "nonstandard" tool available on every system I work with.

(1) Disclosure. I work for the company that wrote Chef and Ohai.

It's not exactly a small cli tool as such, but I can heartily recommend <a href="http://www.zenoss.com/product/network-monitoring" rel="nofollow noreferrer">Zenoss Core</a> for network and system monitoring. It has restored my faith in monitoring-and-alerting software.

Where tools like Nagios, Cacti, etc. all have steep learning curves and seem to be good at only one thing, most often you have a need for an all-in-one solution, and Zenoss Core provides that for free (and Free).

It's hard to summarize, but basically it's an application with web-interface that autodiscovers devices on your network, then monitors tons of parameters, logfiles, ports, services, software, hardware, amount-of-pages-printed, etc. If anything fails or crosses a threshold you get an alert. It's easy to get started: enable/install snmp on each device you want to monitor, install Zenoss on a server, and open the web interface.

The free Core version is good enough for small and medium businesses, while the commercial Professional and Enterprise versions provide some advanced features.

If you ever thought about Nagios, Cacti or the like, be sure to evaluate Zenoss as well.

Paperclip (other use) - if a system is hung (particularly on a single processor, single core, CPU) and you don't want to reboot it, and all else fails, shove a paper clip in a USB port. I've found this to create a fault that allows the CPU to handle user input.

Rubber band - our office has dozens of printers, many of which are connected locally to their computers for security reasons. The parallel cables often pop out ... tying a rubber band around them holds them in place.

Fist - a quick slap on a rattling AC unit, or even a spotty fax, is often all that is needed to keep it going until a Service Tech can arrive.

dsh

Distributed SHell. With dsh you can perform a command via ssh on multiple servers. I find it quite handy when doing a lot of the same things on a serverfarm, at least when it's not complicated. For instance, doing a reboot of the whole farm is just 'dsh --all reboot'. I wouldn't recommend it for using it interactively.
With dsh you can make lists of servers, like a list of all your webservers or all servers located in .uk, and only perform the action on that list. 

ClusterSSH

Sort of the same, it spawns multiple ssh sessions and you can input in multiple sessions at the same time. It's extreme usefull when you've got interactive commands, like aptitude dist-upgrade. I found this very usefull when upgrading a serverfarm from etch to lenny.

The rule engine allows you to do things like: notify me if 80% of the disks in the system are busy 90% of the time over the last 5 minutes; notify me if disk space grows at a rate of more than 1Gb/min; notify me if all processors are more than 75% busy during work hours; notify me of swap space used is increasing more than 5% per second for the last minute.

The tool also allows you to run the programs not only in real-time - even against hosts across the network - but also over an archive file acting as if it was in real-time.

If you want a cheaper version of hotplug you just need a server with bonding and redundant power supplies =)

get your extension lead going to your new rack location and a network cable that will fill that length, plug them in then disconnect the localised rack power and network, move the server then plug back into the racks new network/power =)

Excellent bootable CD (or floppy) for completely wiping the contents of a hard drive. I use it in two ways:

<ol>
<li>Zeroing out a hard drive before installing or reinstalling an OS.</li>
<li>Securely wiping a hard drive before shelving it or destroying it.</li>
</ol>

It's great, and it's easy to use. It runs in about an hour on most of the disks I have ever tried it on, it may require more time for terabyte-class drives, I'm not sure.

This is one example of a good tool that performs one function and performs it right.

Big fan of the camera phone over the last couple of years for documenting consoles/error lights on switches/servers. 
My new favorite tool to carry in my backpack is a FLIP camera. I find it very useful for documenting wire racks/trays, or remote maintenance closets that I need to have a 'view' of from my desk while on the phone with a tech. Plus, it is great to document when someone in the office goes nuts.

I'm wondering about tools that are powerful and that most system administrators either don't know about or don't use (but should).

For one thing, I like the possibility of finding out about a tool that is good and that I should be using - or at least, trying out. I also find that giving these tools their time in the sun (again) can be a positive, letting others know about the wonderful tools that are out there.

Thus, things like sudo, vi, emacs, dtrace, ps, and top are out. I have some ideas but I just hate to skew the statistics...

I'll just wait and see if anyone mentions my favorites.

What tools should every sysadmin use that no one's heard of?

我想知道哪些工具是强大的，大多数系统管理员要么不知道，要么不使用(但应该使用)。首先，我喜欢找出一个好工具的可能性，我应该使用它--或者至少，尝试一下。我还发现，让这些工具在阳光下度过(再次)可能是一个积极的结果，让其他人知道那些很棒的工具。因此，像sudo、vi、emacs、dtrace、ps和top之类的东西就过时了。我有一些想法，但我不想歪曲统计数据.我就等着看有没有人提到我的最爱。
