Diary of a Network Geek

I’ve been doing a lot more on my phone lately.

I’m not really big into the latest and greatest phone technology.  I don’t go out and grab the latest phone just because it’s come out and has new bells and whistles.  No, really!  But, I have to admit, my new iPhone has pretty much taken over a significant portion of my technological life.  And, I’m pretty much okay with that, because I love it.  One of these days, Real Soon Now, I’m going to write up a review of the VNC software I use on it to manage my servers remotely.  But, until then, I’m going to give you a quick high-light of something absolutely miraculous: secure shell sessions for your phone.

Yeah, now, notice that I didn’t write “for your iPhone”, but, rather, “for your phone”.  There are actually secure shell clients for all three of the big smartphone players; Blackberry, iPhone and Palm.
Now, for those of you not sure what I’m talking about, that’s okay, it’s a geek thing.  Secure shell is a protocol that hardcore, professional geeks like me use to securely access remote systems.  In a nutshell, it’s like Telnet, another hardcore geek tool, but it doesn’t pass information like usernames or passwords in “clear text“, which makes it more secure.  And, that’s the reason guys like me use it.  It lets us securely access servers remotely over networks in ways that don’t endanger our networks or users.  It used to be really only for Unix and Linux, but there are secure shell clients for just about everything now.  Frankly, more professional geeks should be using it for a lot of reasons, but many don’t.

Regardless, I think we’ve reached the pinnacle of technology when I can get a secure shell client for every major smartphone out there.  What that means is I can securely access virtually any kind of server from my phone, where there is a speedy enough data link.  Think about that for a second.  From my PHONE, I can securely access servers, wherever I may happen to have the freakish whim to do so and can get a decent cell signal.
I remember back in the days when you had to have an actual dial-up MODEM to get into servers remotely.  There was no method, secure or otherwise, to get into a server from home or anywhere else.  Now, I can do it, securely, from my PHONE!  How crazy is that?  Seriously!
So, if you want to be able to do that, too, here are links to three reviews of SSH software for the various smartphones. They should all have links to where you can actually download the software, if you want it.
SSH for Blackberry
SSH for iPhone
SSH for PalmOS

Also?  There are lots of applications for managing Windows servers, especially for the iPhone.  Check out Managing Servers and other systems from the iPhone.  It’s why I couldn’t hardly wait for the prices to come down to reasonable levels and why I babble about how there’s an app for everything on this iPhone. Really, it’s made so many things so much easier for me, I cannot begin to tell you.
But, I may just try.

I lost one of my USB thumbdrives this weekend.

As cheap as they are, it’s not a big deal, really, except for the lost data. And one or two of the programs on it. In particular, the one that I was concerned about was the Mouse Tracks Windows Domain Report Manager tool.

One of the many things I’ve seen change over the years in the world of corporate computing is how portable and mobile and just plain fluid things have become. Now, I’m not complaining about that, not at all, but from my point of view, that kind of environment presents certain challenges. One of those is inventory of hardware, software and assorted configurations. In the event of a catastrophic disaster, it’s nice to be able to have a current list of hardware with what’s installed on it and how it’s all configured.

Now, there’s quite a market for computer inventory systems at every end of the market, but most of us don’t have a budget that allows for a project team from IBM, so we have to find some other solution. I started to try and work up a Perl solution, but, frankly, my Perl Fu is weak these days, so, I went looking for a cheap (ie. free) solution that was ready made. What I found was the Mouse Tracks Windows Domain Report Manager tool. It’s based on Windows Script Host, so it only works on Windows machines and, really, only finds devices that are part of your Windows Domain, but that’s all most of us have anyway and it is, after all, free. And, it was on that USB drive that I lost this weekend. So, yes, that means I carry an inventory tool in my pocket with me everywhere I go, just in case. Because, that’s just who I am.

So, really, dear readers, you’re benefiting from my loss, since I had to go find it again this week and, therefore, was thinking about it when it came time to post.
Enjoy!

I bought an iPhone on Saturday.

Well, as I’m sure is no surprise to my regular readers, especially those who follow me on Twitter, I finally gave in Saturday and got myself an “upgrade” to the iPhone GS. My data plan won’t kick in until September 17th, when I’ll also have unlimited text messaging and slightly fewer actual voice minutes. The overall effect is to raise my monthly bill just $5, while ultimately giving me more services and, yes, more fun.

I actually debated for quite some time about getting the iPhone, a Blackberry or the new Palm Pre. I have to admit, I was really excited about the Pre, because I’ve been a Palm fan since way back. In fact, at one point I was such a fan of Palm, as a company and a platform, that I registered HavePalmWillTravel.com. Well, that and there was a little joke about an e-mail address and a technological “gun-for-hire”. In any case, I decided against the Pre for a number of reasons, not the least of which is they weren’t on AT&T, where virtually all my contacts are. Also, they’re still unproven in the current market and there still aren’t as many applications for the Pre as both of the other two smartphone choices.
One of the things I really needed my smartphone to be able to do is remotely manage my server or servers. Now, I know that there are remote communication and control apps for the Blackberry, but, frankly, the touchscreen Blackberry just isn’t all that great and the other Blackberry devices have rather, well, puny screens. If I’m going to manage a Windows server, I’m going to need a big screen to see everything and make it all work. So far, no Blackberry device has a screen that I think is big enough to make that happen. So, that left me with the iPhone.

So, within just a day or so of getting my new toy, I had found the free Mocha VNC Lite. Now, I suppose I should have taken a screen shot of that, but, frankly, I didn’t want the hassle of finding a clean, safe shot of my Windows server at the office, so I decided to go with a different shot. Again, since my data plan hasn’t kicked in yet, I haven’t tried the VNC client via the 3G network, but it works disturbingly well over my wifi network at home. When I do get that chance, though, I may do a full review of all the remote clients that I’m willing to actually load on my iPhone to try out.
But, there are other apps that I think I may just get addicted to and this shot shows one of them. Yes, that’s a WordPress client on the iPhone from the same people who bought you the WordPress software itself. If you look closely, you can see that I’ve already set it up for this blog and another one that’s in the works. So, yes, when the data plan is active, you can expect to see both posts and, possibly, even posts with pictures shot on the iPhone. Who knows, maybe even video!

So, as the marketing gurus say, watch this space for further developments!

Because, this is totally why I got into computers.

Yeah, right, sure it is.
Look, these new ads by Intel highlighting the “rockstars” of the geek world are great.  They’re cute.  They’re funny.  But they work because this is so NOT how our society works.  Geniuses who invent things that change the way many of us live are mostly not appreciated in their time.  They don’t have trading cards.  They aren’t the subject of comic books.  They don’t get their faces on boxes of breakfast cereal.
But, isn’t that wrong?  I mean, shouldn’t that be what we reward?  Not the super-jocks who can throw a ball or run the bases or whatever, but the geniuses who actually change the world?

Maybe I live in a dream land, but, well, that’s how I wish it was.

There’s a new version of Wireshark out.

If that means nothing to you, then you’re not one of my geek readers.  And, that’s cool.  Hold on and something more interesting will be coming for you soon.

For those of you who are geeks, check this out, okay?  There are tons of improvements, including a Windows 64-bit installer, improved reports and assorted output, the inclusion of GeoIP lookups, and many, many more.  I’ve used Wireshark, on and off, for several years now and these are really good additions.  I especially dig the ability to lookup where IPs may be coming from more easily.  I often have to deal with international TCP/IP traffic and knowing which is from where can be really helpful.
And, yes, there is still a version for Mac and Linux, besides the new Windows versions.

So, go check this out.  If you didn’t want to fillow the link above to Lifehacker, you can just jump right to the Wireshark site to see their marketing pitch on the latest version.  And, of course, it’s still all free.

So, last month, I was talking about rolling your own distro.  This week, it’s rolling your own LiveCD.

Over at TechRepublic, they ran an article on using some tools built into Ubuntu to make your own, custom Ubuntu LiveCD.  For those of you not in the know, a “LiveCD” is a bootable version of an operating system, in this case Linux, that will run from the CD without installing on the workstation.  It’s a great way to try out a new operating system or bring a portable, emergency software toolkit with you without damaging or changing a PC.

The tool, for my fellow wireheads, is called Reconstructor and the article pretty well takes you through step-by-step on how to do it.  Well worth the read if you’re a Linux geek, most especially if your distro is Ubuntu.

It seems like this comes around on a regular basis.

Server names and naming conventions are a constant source of argument and irritation in big IT departments.  Everyone has their own idea of just what naming schema should be used for the servers and workstations and such on the network.  And, since it hasn’t shown up recently on Slashdot, we were about due for an article on it.  There is; Why do we name servers the way we do?  The comments, if you can be bothered to dig down deep into them and wade past some of the worst attempts at humor, are quite telling.  It doesn’t take long before the relative merits of using quirky, easy to remember names is being quite hotly debated.

The original article  over at IT World, titled Would a server by any other name be as functional?, seems to weigh in on the side of the more creative names.
I’ve worked both kinds of places, actually.  In one job, we used a very precise naming convention that had been put in place after some, apparently, very intense debate.  There, we used the LocationFunctionOperatingSystemNumber kind of naming system.  So that the first Accounting server in Houston running Novell Netware would be HOUACTNW01.  Perfectly clear to me, actually, because of that job.  It’s a logical system and works well enough, though it does lack a certain “zing”.
At most other jobs, though, we tended toward the other way.  Once, I worked with a guy who named his servers after dead musicians and actors, but that was only so he could ping his favorite router and see “Hendrix is alive” come back to him.  Another place, we used various things and it was, well, far less themed and much more confusing.  I think it’s best to choose from a very, very large mythology or naming pool so that you don’t have to switch themes mid-stream.  We had some servers named for “gods of the underworld” and others that were named after space shuttles at the same company.  There was no rhyme or reason to it, really, just what the last guy felt like doing.

I’m not sure what naming convention I’ll finally use when I finally get around to redoing my network at home.  It’s hard to get motivated, you know?  When you do it at work all day?  Makes you feel sorry for sex workers and gynaecologists, not to mention urologists, doesn’t it?
(Yeah, this is what happens when I stay up way too late.  Or is it too early?)

Well, okay, maybe not non-geeks, but non-network-geeks, at least.

As many of you well know, I am almost always pressed for time. That’s partly due to my work, which seems to include more and more front-line support and less and less networking coolness. It’s just the way things go. In any case, …

So, don’t be intimidated by this. You can diagnose most of your own network problems. Just head on over to the Linux Journal’s website, where Mike Diehl has written a pretty comprehensive article on Troubleshooting Network Problems. Oh, and don’t let the fact that it’s on a Linux website throw you, he has tips for Windows users, too.

Sorry there wasn’t a post yesterday, but I was pretty beat from a tough week at work. Also, I upgraded to WordPress version 2.8 on most of my sites last night.
Hopefully, you’ll be enjoying the extra speed it’s supposed to give me.

Okay, it’s not quite Apple’s Time Machine, but close.

Mac users know all about Time Machine. It’s a really great feature of OS X that makes small, incremental backups of your system. It lets you roll back changes to both system and data files to a particular time and day. The backups work pretty quietly and seamlessly, too. I have to admit, it’s one of the coolest features of OS X.

Well, if you’re a Linux user, now, you can get the same thing, more or less. It’s called Back In Time, and it requires a little more knowledge and setup, but the idea is basically the same. Oh, and it’s free, but if you all use it, and like it, they do as for donations to support their efforts.

If you use Linux, it’s worth checking out.

(And, yes, I know I’m late and this is not the post I talked about at the Geek Gathering Friday night.  I also overslept by an hour this morning.  I think it’s going to be a long week.)
