Re: [Wlug] Information for Linux newbies?

by Brian A. Dewhirst

One of the most basic things that I had to learn with ubuntu was how to access the support which exists... and there is a lot of it on the web. Googling "howto ubuntu FOO" can kill half of my problems in the first ten hits. Synaptic and the Update manager etc. are also key.

I dunno, it's more of an urge to do something else, not a true desire to move off. Also, I have noticed that alot of packages are still staying with 7.3 or 8, and that 9 hasn't seemed to be as popular. Hard to tell...

See Charles> http://fedora.redhat.com/ for more info about the project. But none of this exists right now, and I want to rebuild my system this weekend if I can. :] Of course, nothing says I can't play with this stuff later one. Also, some of the rpmbuild and rpm commands have really ticked me off, since I consider the syntax and errors messages to be really baroque and unhelpful. Especially when trying to build a SRPM package, and it dies for no frigging obvious reason. And since I'm planning a fresh install, I've got the Debian and RH9 disks to play with. So maybe I'll just go with Debian for now and see how it goes long term. Thanks for the input. John

"bryon3245(a)netzero.com" wrote: > > What firewall under linux would you suggest, > what would the best way to set up a firewall-router box with two nic's? I suspect this depends upon the distro. I recently upgraded my gateway box from SuSE 6.3 to SuSE 7.2 and found that the default "Personal Firewall" was exactly what I wanted. (I just use the web for browsing and email so all my connections are started by me and so can easily be "masqueraded" --- hidden from the web). It seems to give you essentially the same thing as that Linksys box Steven Daukas (is that a real name?) suggested --- basically masquerading stuff coming from within and blocking anything unrelated from outside. Again, setting up the nic's is the same with all distros if you approach at the under the hood level but will differ if you use their administrative tools since the latter again are distro dependent. In the SuSE case, their Network Manual, pp 149 guides you through reasonably painlessly while still providing some idea of what is going on. Now, all bets are off if you want to provide some service like a web site or ftp server because then you have to do more than just masquerading and that does require you to become more familiar with how a firewall works. As to the two nics, basically you will set up one, say eth0, which is connected to your cable/dsl modem as a dhcp client which will get its ip address from the isp (I assume that, since you are asking a basic question, you did not spring for a fixed ip address which is more expensive; I also assume that you have a broadband connection since you specify two nics). The other nic, say eth1, you set up with a fixed IP address on your local net, for example, 192.168.1.1. If, at this point, your head is swimming, you can either look at the slides from an old WLUG presentation on networking (go to WLUG site, find "Past meeting information" and go to the March 2001, stuff. Slides 47 and 48 give a back to basics summary of the difference between a hub and a switch incidentally) or look into the manual(s) that come with your distro and see if they are as useful as those for SuSE or, get back to me (I suggest directly so we do not clutter the WLUG mail list more than I have been doing lately :-) ) and I am quite willing to try to walk you through the process on a slower one-on-one step-by-step process. The hazards here are that (1) I can easily get in over my head (but, I believe, am willing at least to let you know when that happens) and (2) you may end up wishing as in the Tom Lehrer song "You should never have let me begin ... " :-) doug

Maintaining Gentoo x64 > isn't terribly hard, and you can use memory more efficiently. Gentoo user here, too. Although I haven't done a fresh install in quite a while, I just keep updating. What I like best about Gentoo is picking and choosing which packages to include and leave out, both applications and libraries. For example, the other day I wanted to install "gtkpod", but I really don't want to have Mono or QT4 installed on my system, for various reasons. Doing a test install, I can verify that they are left out: # emerge -ptv gtkpod These are the packages that would be merged, in reverse order: Calculating dependencies... done! [ebuild N ] app-pda/gtkpod-1.0.0 USE="aac flac mp3 ogg -curl" 1,856 kB [ebuild N ] media-libs/libgpod-0.8.0 USE="gtk iphone python udev -mono -static-libs" 975 kB [nomerge ] media-libs/libgpod-0.8.0 USE="gtk iphone python udev -mono -static-libs" [nomerge ] sys-apps/sg3_utils-1.30 [ebuild N ] sys-apps/rescan-scsi-bus-1.48 21 kB [ebuild N ] sys-apps/sg3_utils-1.30 863 kB [ebuild N ] app-pda/libimobiledevice-1.0.4 USE="python" 404 kB [ebuild N ] app-pda/usbmuxd-1.0.6 57 kB [ebuild N ] app-pda/libplist-1.3 67 kB [ebuild U ] dev-util/cmake-2.8.3-r1 [2.8.0-r2] USE="ncurses -emacs -qt4 -vim-syntax" 5,310 kB ... The USE= "-mono" and "-qt4" flags indicate that the listed packages will be built without that support. Gentoo handles that by passing the necessary options to "configure" when it builds the package, and that is IMO the main point of using a source-based distribution. If you *did* want support for mono, you could edit "/etc/make.conf" (system-wide) or "/etc/portage/package.use" (package-specific), add the "mono" flag (or remove "-mono"), and try again. For better or worse, I think gentoo kind of peaked in popularity several years ago.

more on event correlation...

by Mike Peckar

Nice meeting you tonight, Chuck, and THANKS for the redhat cd's... sec was the freeware event correlation tool I spoke of tonight: It is a straightforward perl script and doesn't implement a full state machine, but it nevertheless provides some inklings of what more complciated event correlators do. Check it at http://kodu.neti.ee/~risto/sec/ The best commercial event corellation tools IMHO are Nervecenter, Taave, Smarts, and Netcool. Each has its niche where it's best in class, and there are others, like HP's ECS, Logec, G2, etc. My friend Doug Stevenson is a specialist in event correlation and wrote the Maji spec: the open source event correlation engine being developed under the umbrella of OpenNMS (yeah, so, it'll be java - but it will also be very feature rich). He masterfully defines some of the layers of granularity that one might see amongst the different offerings in the Event Correlation space. Types we talked about tonight include event correlation (reducing traps) and device correlation (mapping switch states to events). His definitions are listed below... Mike <snipped message> OK... Here goes... § Event Correlation § Alarm Correlation § Device Correlation § System Correlation § Service Correlation § Performance Correlation § Security Correlation Event Correlation - This is a correlation where multiple events are filtered and processed, thereby reducing the number of events presented. This is primarily done with event tally counts and trap problem verification. Alarm Correlation - This is a correlation of alarms and alerts depicting true problems or root causes and their current status. Side effect alarms or alarms occurring as a result of a root cause alarm are suppressed or become subordinate to the root cause alarm. Device Correlation - This is a correlation of devices, their specific internal components (both hardware and software), and the device's behavior with other devices. Additionally, device correlation lends itself toward configuration management as it is a dynamic inventory of devices, subsystems, components, and behaviors. System Correlation - This is a correlation of devices and managed objects as they pertain to an overall system. This level of correlation enables one to manage and classify a conglomeration of managed objects as a manageable entity. Service Correlation - This correlation is used to determine the devices and systems that make up an IT service. In essence, this is the correlation of managed objects and systems to business rules; similar to a translation of terms from computers and systems to business services. The Service Correlation can be extended to customer impact analysis, business profitability impact analysis, etc. Performance Correlation - This correlation is used to determine the effects performance has with regards to a fault. It is unique in that performance correlation can be applied to enhance the correlation of all of the other categories. Security Correlation - This correlation is used to determine the degree of threats caused by security incidents. It is unique in that security correlation is embedded among all the other six categories described above. HTH, Doug...

No costs are involved to be a member. We may have to buy some tapes; they use miniDV for digital recording. Anyone who uses the equipment must get a bit of training. That's not a big deal.
