uptimes
Monday, October 20, 2008, 12:09 PM
If you need to measure uptimes on windows machines, then you need to
download the uptime tool. It gives essentially the same information as: Posted by Administrator net statistics server | find "Stat" but it can be run against a variety of OSs from a single host. I run it on a Vista machine against XP, 2003 and 2008 servers. |
Good/Bad/Ugly
Monday, October 20, 2008, 09:54 AM
We use a variety of software and services, and I have experience with a
variety of companies, so I thought it might be helpful to share my
experience and opinions.Posted by Administrator * AIX - I've worked off and on with AIX for a couple years now and I've found it to be an extremely stable and reliable platform, but not a terribly easy one to work with. I'd recommend using BSD or Linux or even Windows if you're developing a new project instead, but if you need a stable system and have AIX available, it will do nicely. Support is expensive and you need RISC to use it, but uptimes and hardware are comparable to what you'd expect from big iron. * CentOS - This is the Linux distribution I'd recommend for most enterprise systems. It has all the goodness of Red Hat's commercial software without the price tag. If you're capable of managing your own Linux systems and need enterprise class software as inexpensively as possible, then CentOS is a good choice. * RHEL - Red Hat Enterprise Linux is going to cost you, but when you pay for it you get the benefit of updates from a team committed to providing secure and reliable systems. I recommend this for platforms that will be exposed to the Internet (for the sake of security) or for platforms where you expect more than a thousand users in a day. * Network Box - This is a managed network gateway and security system. Essentially it will filter all your Internet traffic, scanning for viruses and keeping the system * EMC - I loathe EMC. I've talked to several salespeople who promise everything that you can imagine and when you pay for something, they start having a vary hard time backing up any promises. They kill good companies like VMWare and Legato. Having talked to other IT people, I know I'm representative of the majority of their customers, stuck with them because they sold us something so expensive that we feel obligated to make it somehow work but with a deep loathing for the providers. (I got a new job, so I'm not stuck with them anymore.) * SEP - I don't particularly care for Symantec as a company and I don't care for their software, but Symantec Endpoint Protection is a decent package for the money with decent network administration controls. SEP is definitively better than previous generations of anti-virus. |
NFS with AIX
Wednesday, September 10, 2008, 09:24 AM
In the past I've experimented using NFS served from Linux and mounted
on AIX. Some issues led me to far that sync was not handled correctly
for AIX 5.3 with default choices, but just for reference, I'd now
recommend exporting something like:Posted by Administrator example.com(rw,insecure,all_squash,anonuid=0) |
Spam sucks
Friday, September 5, 2008, 10:48 PM
I've been getting dozens of spam entries as comments on my blog daily.
They don't show up because I enabled a comment moderation script a long
time ago and regularly delete all the entries. Today I decided to go
ahead and test the associated spam block tool, just to keep down the
amount of maintenance I've been having to do. If you've made a comment
and wondered what happened to it, well I deleted it. So much spam on the
blog means that I don't even take the time to read the comments
anymore. Hopefully this will clean it up somewhat.Posted by Administrator Update: This was applied on September 5, 2008. On that day I received 27 SPAM entries. After September 5th, I have received none. |

Okay, this totally cracked me up:Posted by Administrator http://www.angryalien.com/1205/starwarsbuns.asp It's Star Wars reenacted in 30 seconds, by bunnies. In other news, openbsd rocks, but the people who use it, not so much. |
Economic news

When I heard about the Freddie Mac and Fannie Maye "bailout" (actually
relaxing of regulations and potential for additional credit) my gut
reaction was displeasure. Now I hear that they are held in large part by
foreign investors, and chartered by the US government.Posted by Administrator On the plus side, the dollar gained again. Woo-hoo! |

Vigilante Justice
Sunday, April 20, 2008, 10:09 AM
I was just following a poll about identify theft and considered how
much more effective enforcement would be in this area if the victims
were allowed to go after the criminals.Posted by Administrator After I pondered this for a couple minutes, I thought, so why can't they? Is it illegal to find someone committing identity theft and detain them until the police come to take them (and probably you) into custody? A quick skim over a wikipedia article on citizen's arrest and the answer is maybe. It certainly might be. Are we as a society unwilling to do anything about crime? |
IP management
Friday, April 18, 2008, 03:52 PM
You need to know what is on your network, and you need to keep your
information current. How? Well, why not ping everything in range and
then do arp and dns lookups for the active ones? Here is the script I
used:Posted by Administrator
