We started using Nagios just over a year ago as something quick and simple while we were building our infrastructure (was still beta in those days). It does the job if you have a small site, but does not scale well. We've just switched over to OpenNMS. It does take a lot more effort to configure and get up and running (especially as we're not running it on Linux), but it's worth it for the additional flexibility and features you get. It helps if you have someone who understands Java for the implimentation as the documentation is a LOT more incomplete than Nagios.
If you understand SNMP and systems monitoring and management then OpenNMS is for you. If not, then go for Nagios.
1. This is not a feature of Solaris, but a feature of the Veritas File System if you purchase that package. Linux would have it too if Vertias made a Linux version.
2. Linux does this too. Maybe not schedulers yet (let's not get into that battle) but protocols, filesystems, etc can all be modules. Not too sure about the architecture stuff though...
3. Have you ever had a close look at a Solaris binary patch? Most of them are just new files/libraries/drivers. RPM spring to mind? Even if it is a kernel patch, Linux still does that. One thing that Solaris does that RPM does not do (can't comment on.deb or yast - never used them) is keep old patches, so that if you apply a patch and it does not work, it's easy to back the patch out and revert to the old one in one command.
4. Never tried on Linux. I have done server failover of NFS and use a VIP with the service. Works a treat.
5. Never played with the automounter on Linux or Solaris so can't comment...
6. K, something I agree on.:D
7. Hehe. Yes it is a stupid thing to say, but if someone donated enough hardware to the author to test all scenarios he'd be able to change his wording...
8. Yup, would be good.
9. OK, small clarification here. To jumpstart a Solaris machine you do need console access. First off you read the MAC address from the boot prom. You then define the client on the jumpstart server, assign and IP address. All this is linked to the MAC address of the box. Then you go back to the new machine and type in "boot net - install". Then you go back an hour or so later and it's done. RedHat does have something similar to jumpstart. It's called KickStart...
10. LiveUpgrade is nice. Never used it, heard a LOT of horror stories about it. We just do upgrades the traditional way - helps us sleep better a night...
I used to work for a company that provided a lot of bulk SMS services (NOT SPAM!), and we worked with all the major service providers here in the UK. We found that particularly during peak times, most of the operators would have no problems with dumping a batch of messages from their SMSC's, particularly if they had not been delivered for a few hours (phone memory full, phone off, that kinda thing).
I used to shop a lot online when I lived in Denver, CO from King Supers. When I moved to the UK I thought I'd try the same, but had the same problem as veg. Deliveries are almost always late, quality sucks, stuff missing, rude delivery guys...
I tried again not so long ago with a new UK company called Ocado. They're much better than all the rest! The only problem is they only serve the London area, but they've only been delivering for about a year now, so they're probably waiting to make more money before expanding...
Highly recommended if you're fed up with Tesco's and the rest...
I think RedHat are going a good thing. Why waste the effort on a SPARC version of Linux when Sun is shipping Solaris 8 for the price of the Media ($75). You still have all the same old tools available. Sure you can't do the ultimate lazy thing and just grab RPM's, but all the source is out there, as well as the EGCS compiler.
I'm very happy running Solaris 8 on my little Ultra 5 workstation. Still use WindowMaker as my WM, still run all my happy DocApps - life is good...
RedHat can now focus on important things for the disto as a whole and for the other platforms that are not as well loved by *nix vendors, like Alpha...
If you're willing to sacrifice a bit of speed, then why not move your web sites to South Africa. Here are a few reasons:
1) AFAIK there are few laws here regarding the Internet related things. Child pornography is the only one they come down hard on. 2) Even if there were, our Law Enforcement groups are so useless that the only crime rate that is on the decline are traffic violations, which they are coming down hard on. 3) Free speech is very well protected here, especially in relation to our political past. 4) There are a few companies that will host your domain and give you self administration for a very low cost - for less than US$50 per month for 10Mb hosting. This price is dropping as our currency declines along with the situation in Zimbabwe.
The reason I say you'll sacrifice speed is because we still have a monopolistic Telco, and bandwith is _EXTREMELY_ expensive. It will change in the next fews years though...
As a citizen of South Africa, a country which manages to be both 1st and 3rd world at the same time, I think I am fairly accurate when I say that the Internet is not an issue with those in the 3rd world. They have more important things to consider, like feeding themselves. Most of them don't even know what a computer looks like. I think that once things like the extreme poverty, hunger and debt which exists with the majority of these societies, then they may have time to start looking at what the rest of the world is doing.
For those of us who are involved in IT, bandwidth is hard to come by and extremely expensive. Hopefully that will change once the communication monopolies crumble.
There is a company here in South Africa who has successfully done this for about 3000 workstations (AFAIK). They are called UCS. I don't know how much they'll tell you, but it never hurts to ask...
I've got a lot of emails come in with various questions, and all I can say at the moment is this: Watch the NVidia web site in about 2 weeks time (that is when they told me they would make some formal announcements).
Also, the TNT does not have 3D support. I don't have any details on the 3D implementation for the TNT2, but my guess would be Mesa.
I've emailed my contact to ask him if I can publish the message he sent me and maybe his email address, so if I get it I will add it to these comments...
Until then, let's see what appears on their web site...
