Monitor your Linux boxen with iStat for the iPhone

So I came upon an app the other day while browsing on my iPhone. iStat. It monitors your uptime, network I/O, RAM usage, etc.. There was another app that just needed SSH access but that was another $2. Anyways, iStat has a Mac OS X, Linux, FreeBSD and Solaris port of the agent. Just simply install the agent on your boxen and done!

 

It's pretty simple to get it working, I'll go over the steps that I used on Lenny.

Pourquoi?

I've come to realize that no one reads a blog where people (such as me) babbles on about their life. Know why? No one cares. People dig tutorials on the internet, if they wanted to read stories they'd pick up a book.

 

I'm in the process of upgrading my Hackintosh from 10.5.2 to 10.6. Shouldn't be too much of a pain in the ass, but oh well.

 

I've gotten a serial terminal working on my Thinkpad. I can know get a [virtual] terminal, via serial to one of my servers which is great. I could SSH into them, but plugging shit in is much more fun. I'd suggest those who want a quick terminal to check this out.
 

Schematics

I've been profoundly confused on what to do with two new servers. At the moment, I have a total of three servers; a BitTorrent tracker, web server and NAS (NFS server). Now, what I was thinking was setting up a load balancing scheme using VS via NAT. Essentially, build one of the servers as a load balancer and turn the other one into a http node. The only problem with that is redundancy. Say if the load balancer fails for whatever reason, I'm screwed.
 

Dual booting Debian

Getting Debian set up to dual boot with XP is extemely easy. I installed it to a second harddrive, installed GRUB to the MBR of the first drive and auto detected XP! The only thing now that's pissing me off is trying to get the NVIDIA drivers to work, so I can have triple monitors under Debian. Gah! I've tried everythimg but it's not working.

I built a Twitter PHP bot (sorta) the other day. It updates itself if one of the servers are down. I'll release the source or something.

Anyway, I'm off to go watch TV or something....mmmm TV...........

Log server/firewall

Flippy, my webserver which died back in December/November-ish has been sitting my desk, lifeless. So, I decided to turn it into a log server and firewall (running Debian, of course). I'll post some pics and specs later on.
I was looking into getting a switch (over a hub, which I have now). I think it would greatly improve my network performance (A D-Link DES-1024D 24 port 10/100).

Anyway, I haven't made any money with AdSense or PayPal donations, so that sorta sucks....

Bored

This is probably going to be a boring and pointless post.
I got a rack for all my computers (except my main quad-monitor one). So, I got my server plus 2 other computers & 3 monitors...add the router and switch on the rack (I also have another computer but with no case). Surprisingly, my server is running quite cool @ 26C (CPU) and 27C (Mobo).
I installed Fedora 9 'The Spin' version last night on an old Dell. Quite slow (only 128MB RAM in the system) so now I'm installing Easys, a Slackware based distro (Running KDE (which isn't old-computer friendly)).

Furthermore, I installed Xubuntu 8.04 (8.10 on the 30th!) on an old Thinkpad (which I love). I got it running pretty good, considering I was using Fluxbuntu 7.10 before.

Debian Web Server

Well, I turned one of my [8] computers into a file/web/FTP/SSH/etc.. server. I got a no-ip.org free DNS so far, and its working great. And of course, its running Debian, the greatest distro of all time. Instead of wasting time installing PHP, Apache, etc.. separately, I just used LAMPP (XAMPP), which isn't very secure, or so I've read. I also got another HDD mounted as /opt so all the files are mounted on their. Oh, thats right..the spec of the server:
Intel Pentium III @ 450mhz
512Mb RAM
10GB HDD as /
40GB HDD as /opt
