I just bought my sidekick (version 1) about... 3 hours ago. I went into the "Catalog" program and downloaded the 10 dollar SSH client. Woot! 48 characters wide. Haven't figured out how to toggle around in screen yet. Anyways, as a (barely) netadmin, this is like, the coolest thing in the world. I can telnet into the ciscos from the movie theater or while I'm out at a nice italian place with a beautiful gal. Yep. My life just got so much better. Yeeeeeeeep. uh huh. (facetious aside, the program is very usable, with a 3 second latency)
If you took your average SUV on the road and filled the passenger and rear seats with something crazy like cargo or people, most of us anti-suv folks would have a lot less of an issue with them. my 2 cents
yeah but each of us that gets it for free knows a guy who does nothing but buy brand new tech manuals and then stuff them under the passenger seat of their car three nights later.
I always thought military desks had two machines on them. A public internet and a military internet, and at no point were they ever interconnected. Is there any shade of truth of that *at all* in any branch of our military? It certainly sounds like any casual remark anyone might make at the watercooler, but it'd be interesting to hear from someone who's been there.
4 years ago I ended up with a Sparc Server 20, I think it was called. Down in an Urban School System somewhere in Rhode Island, my first time on a field dispatch.
I was doing an IP renumbering, and I reset the default route on their web server. I was telnetted in at the time, from another room. "Oops, I just broke the default route and I saved it in the start up file. I need to reset this at the console." The head IT lady goes "What's a console?" I explained it to her. She walked me up to the console, all remaining 50 keys on the keyboard and shattered monitor and everything.
Walked out of there with IIS running her website, lugging the sparc server 20 to the trunk of my car. It was a horrible first experience. I learned that you never get free hardware twice!
Two winters ago I had finally hit a breaking point of cruft. 11 computers weighed my personal space down, sparc servers and stations, sgi indigo2s and dumb terminals, countless x86 machines in varying states of decay. Sounds like you? In a panic, I updated my slashdot sig announcing that my lan was for sale, more of a joke to myself, a poke at my own sloth. Amazed at an almost immediate response with a serious inquiry, I reconsidered my offer and realized, "why not"? What had that pile of crap done for me? It caused me anguish, it made me think every single night coming home from work, "one of these days, I'm going to clean this place up". And so I went ahead with it, and sold everything on my lan for 400 dollars. I got 1 new machine with it, and 10 months later, an ibook (with other money) I haven't looked back since. In that time I've started, and completed, many of the mundane backburner projects that were always on-hold for seemingly forever. My point to this post is, if you haven't used a thing, and are keeping it because you think you might, why not just get rid of the thing (and this, a chance to do it properly, and for free!) and not let it vex you, sitting idle in the corner, calling out to your procrastinations... (admittedly, 2 of the 3 boxes i mailed were lost or destroyed. the third, the cables, was received a-ok. the buyer was upset until i told him i had insured them. somewhere, there's a little old lady with a bright purple indigo2 full of potting soil and philodendrons...)
i used to have a turkmenistan domain name, which ended with.tm (get it? the trademark domain! ha. oy. i was a dumb highschooler.) Anyways, my rdns pointed at the.tm address, and when I went to download the secureCRT package, with strong crypto, the website said to the effect of "Go home terrorist!" I had to update my DNS entry to download the darned software.
Hrm. One of the things I let my server do for me is emulate a giant grandfather clock. Cron plays the wave files. People always ask me where the clock is, but it's just coming out the stereo.
If I set it up to do quarter hour chimes, that would be a rather interesting way to announce network meta-data: The louder the volume, the more stuff going on that I probably don't want. I could make it two dimensional by using sound and pitch, and I wouldn't even have to do any fancy math stuff I don't know. I could just make 8 different pitches and gradiate using that.
I've been doing exactly this same thing for a while. I found that it got extrememly obnoxious, so I dumbed mine down to just play a wave file whenever I get pinged by someone pinging me from a command line ping. I don't know why the length is different than the crap pings that come in every 8 or 9 seconds, but with this swatch definition below, it seems to trigger only when I am pinged by hand.
So, put this in your swatch file that watches your firewall log:
That script just locks the darned thing so it doesnt pop and crack if i get pinged twice:
ping-wave.sh: if `grep OPEN/etc/pingwatch.lock 1>/dev/null`
then (echo -n >/etc/pingwatch.lock) && (/usr/bin/play/usr/local/site/etc/soun ds/$1) && (echo OPEN >/etc/pingwatch.lock) fi
I also used the naturalvoices website to make a nerdy computer lady announcing new entries in my arp table. You can grab wave file too if you want. Here's the script I have for that:
put this in your/etc/crontab or whatever:
0-59 * * * * root/usr/local/site/bin/arp-watch
and then make the above command contain this:
#!/bin/bash
for each in `arp -n |grep -v "Address"|grep -v "eth0"|awk '{print $3}'`
do
if grep $each/etc/arptable 1>/dev/null
then:
else/usr/bin/play/usr/local/site/etc/sounds/new.arp.entry.wav && echo $each >>/etc/arptable
fi done
if anyone can improve upon my bash, please, i have no ego.:D

Betcha you Windows guys didn't know I could build a video streamer using 2 lines in a Bash shell, did you? And people say Linux is sooo hard.
Doctors go to school for 8 years to write 2 lines on a prescription . . .
Wouldn't work for a data center, unless of course you wanted to run it inside a pool and send your techs in with scuba gear.
Hot damn! My techs smell worse than the gear -- anyone know how long they last underwater? (they're all MCSEs)

They got lucky.
i'm surprised i havent heard of a worm that modifies the host file on the machine in a similar manner.
yeah you should totally check ebay out online!! thay're A+++++++++++!!!!!!! HILEY RECOMENDED

agreed. make it so!

rumor has it that quite a few normal day activities transpired on that particular date.
Did it spit out 40 cents when you clicked the 'X'?
the weirdest place *i've* ever read slashdot from was the scooped out inside of an 800 pound miracle grow pumpkin, via my wireless ibook.
the sexiest solution is to get one of those 1 bay sized computers that mount right inside another, regular sized machine, and let it be your firewall.
Want to get rid of something for free?
I kid you not this ALWAYS WORKS.
Put it outside on a table with a hefty pricetag overnight, like a yard sale you didn't clean up.
Every single thing I've put out on the front lawn like that, including a carrion mini-fridge, groaning for burial, has been stolen!
