I'm not verey experienced with bandwidth limiting. I did play with mod_throttle, and all it did was actually allow all traffic until the limit was reached, and then deny the next new connections. Hmm, not too great actually.
I'm planning to try out mod_bandwidth, but I dunno if it works different. Bad link (sorry, I don't feel for html now): http://www.cohprog.com/v3/bandwidth/doc-en. html
I tried playing with QoS on linux 2.4. According to the documentation it's actually quite hard to have that functional, because if you have a 10 Mbit connection, it will shape the traffic elative to that. But 10 Mbit is not always the same. If you have lots of lost packets it will behave different then with a perfect connection. In my experience I couldn't reliably limit the traffic on a 10 Mbit connection down to 80 kbit (almost 1% of the 10 Mbit). My cable connection of 16 kbyte still could get choked. Maybe I should just get a card of 1 Mbit and try again, the numbers might be better then. Or hey, a card of 100 Kbit:-) should be doing perfect.
Hey, does ext3 have 3 options. It has journal, ordered and writeback. Now I don't want to lose data, so I'd use journal, which is also the slowest option. In the benchmarks posted here last week between reiserfs and ext3, it was ext3 which was faster. But it was only benchmarked with ordered and writeback. So using journal will be slower, which would make it camparable with reiserfs (with notail). Interesting.
Now, I'm not interested in XFS, sorry, but if XFS has options like this, using the "don't-lose-data" option will make it "just as slow" then.
Forgent has the sole and exclusive right to use and license all the claims under the '672 patent that implement JPEG in all "fields of use" except in the satellite broadcast business.
I assume JPEG2000 is still JPEG, only a bit different, so that would be covered here too.
Are rpms still such a pain in the ass to create? With dpkg, all you need is a "make clean" and "make install" target, and 2 minutes with dpkg-make and you've got a deb of your own software.
In essence, Yes. You make a specfile which mostly consists of macros; like %configure, %make, %makeinstall.
Of course you have to specify other Metadata, like License, Source, Patch1, Patch2, Url.
You can make a filelist yourself, where you choose which files end up in the package.
And if you're packaging something that uses libaries, dpkg-buildpackage will automatically figure out what libraries you're using, what packages provided those libraries, and then automatically add them to the package's dependency list.
Yup, rpm uses on mandrake the scripts/usr/lib/rpm/find-requires and find-provides.
You can manually add Requires or Provides to the specfile, like Provides: smtpdaemon. A difference is that rpm uses mostly files from libraries as dependencies, while dpkg uses packages. In the end that should just work the same.
Combine that with the ability to easily make your own sources for apt, and making many workstations is as easy as creating one deb file that depends on all the packages you want to have on a workstation. Just add your local source to/etc/apt/sources.list on a new workstation, apt-get update, and apt-get install ourworkstationload and it downloads the latest version of everything and installs.
Well, if you use apt together with rpm, you can just do the same I suppose. If you use urpmi with rpm, you can use genhdlist which makes a hdlist.cz file with the rpm-headers. You can then use "urpmi.addmedia name ftp://ftp.bla.org/RPMS with hdlist.cz" and install packages from that repository. And for the fake package, you can make a specfile without a real tar.gz and filelist, but with your own defined dependencies.
apt and dpkg rock compared to rpm.
There you go again. You can compare dpkg and rpm. And you can compare apt+dpkg and apt+rpm or urpmi+rpm. You cannot compare apt to rpm, in the same sense that you cannot compare apt and dpkg.
rpm of course isn't anywhere near as snazzy as dpkg: you basically can't do remote, incremental upgrades without reboot
I always thought that it were the "losers" in de Debian userbase who don't know anything, but it seems that it even counts for project leaders. Dpkg and rpm can do just about the same. You can use a frontend for them to handle the dependencies, like apt or urpmi. With rpm you can do incremental upgrades. I'm running Mandrake Cooker for about one and a half year, and it mostly works (ok, it's a development version of Mandrake). Rpm can do post-install scripts and all the rest. And you can upgrade from a gcc-2.96 distro to a gcc-3.1 distro. It annoys me to hell when I read messages from Debian users on forums or on Usenet like "rpm sucks" and then try to explain why. Now, if even project leaders talk this kind of shit, it explains to me why the Debian userbase sucks. Well, I can only assume he hasn't seen rpm in 5 years or so..... That's the only excuse I can think of.
You did not mention which Linux dostro's you actually tried. I assume there's a lot of difference between RedHat/Mandrake and RedFlag, which is aimed at the Chinese market/userbase.
Of course you can't put real value into statistics without finding out what the reasons are from people changing their webserver.
But I find it odd that when an expoit, worm or virus comes out for a certain webserver, that webserver rises in marketshare. Like the rise of Microsoft IIS, after Code red, and now the rise of Apache. Would it then be true that bad news is even better marketing then no news? Is that why Microsoft Windows is even so successfull?
yeah great lets see them actually use gcc3.1 before redhat
Nice flamebait. They are already using gcc 3.1 in Mandrake Cooker, their development distro. They built everything with it short after the release of 8.2. They tried before, with Mandrake's rpm-rebuilder robot, but a lot of software didn't build with gcc 3.0 then. With gcc 3.1 and 3.1.1 things look better.
They were the first with devfs in mdk 8.0 I believe, allthough that might have been a bit early. They were the second distro to use apt-get (after Connectiva), but they switched to their own tool, urpmi, which is working rather good nowadays (apt-get for rpm isn't perfect yet too, you know). So all in all, it seems to me you put out a rather cheap flamebait; you mostly lack the right information.
Yup, this is something I'd like to see improved as well.
Like changing your Resolution and RefreshRates on the fly might be a nice option.
No more fiddling to get 85Hz as a VertRefresh out of a videocard/monitor that can handle that just as a maximum.
There are several distro's that can run from cd. There's Demolinux, which is quite nice. It comes with gnome and kde and so. There's the Linuxcare cd, which is like 100 or 200 Mb in size I believe. There's also the Suse live evaluation cd, which I have no experience with. Suse also offers custom firewalls running from cd.
I'm not into it that much too. But simply said it starts different processes. The parent process starts with root priviliges, and the child processes handle the actual connections, and do not run with root priviliges. For things like authentication the child communicates with the parent. Hmm, would that mean a new connection needs to authenticate itself twice then? (in 1 login) I assume so. If the child gets corrupted, or someone tries to break in, he will not have the root priviliges of the parent process.
In previous ssh versions it was always running with root priviliges, even if you were logged in as user. So every exploit in openssh is immediately a remote root exploit.
This is sort of the same model that Apache has, one root parent, the rest runs as user www or whatever. The same as postfix, the secure alternative for sendmail, which also runs only as root I believe).
I am already frightened by Mandrake. I believe it is a poor choice for Linux users. Linux has not yet become "dummy" enough for the vast majority of users and Mandrake makes it too easy to use and create problems for people.
I'm using Linux now for three years, but I think the "dummy" tools are excellent.
For example; in the beginning I used lpr, ghostscript and apsfilter for printing.
Nowadays almost every distro uses Cups, which had horrible docs a year ago. And I didn't understand one thing of it. There were a few frontends like the webbased interface, but it just didn't want to work with my Epson inkjet.
There comes Mandrake with Cups and printerdrake. Just turn on your printer while installing, or while running printerdrake, and it gives you a recommended driver setup.
No problem with cups since then.
This is just one example, but the Mandrake stuff is quite good imo.
Invididuals that buy this package are going to be open to plenty of exploits, problems, etc. It is going to create a large headache for the rest of us.
Mandrake in Walmart may frighten you, but comments like these frighten me.
What exploits do you mean?
Every piece of software has exploits. After a while there will be known exploits. As long as you install the updates it all should be fine.
Now the question is how many people will actually use the updates, but that's the same story on every OS, especially Microsofts OS's.
I just hope that Mandrake realizes this and moves to at least limit the possiblity of widespread issues that MS has due to the same reasons.
I agree with you here.
I just hope it will have no services installed, and the services that are installed, are only listening on the localhost interface.
Correct me if I am wrong, but I'm pretty sure the rules of "first sale" do not include the right to photo-copy the book and sell the copies or even give them away for free.
Yup, I guess you're right.
After all;
mv != cp
move != copy
moveright != copyright
It might be offtopic, the topic is restricted to UnitedLinux, but I can't believe the topic will generate 10 interesting or funny questions.
I was wondering what the longterm plans are for OpenServer and OpenUnix. From what I heard, you will be releasing an updated version of OpenServer. Is it just bugfixes, or are there new features added? And will it be the really, really last release of it?
And OpenUnix, it's a great system, especially for smp or fail-over clustering. It will be around for x86/ia32 for some years. Will it be ported to Intel or AMD 64 bit machinery?
And also, are there parts of those systems that you are planning to release under the GPL? You have released some old Unix utilities, like awk. Is there anything interesting, we should look forward to?
It's just that KPN and Qwest do not want to invest much more money in KPNQwest. So the plan might be to just let it explode, buy the remaining assets, and start a new company.
That's a likely scenario here in Holland. It is what happened to DAF (trucks) and other companies. They go broke, and in the same time they start a new company with the bought assets of the old one. Your debts are cleared, and the tax accountants aren't wanting money from you anymore.
Still I expect it would cost money to buy the assets, so if they really do not want to invest anything in that network anymore, it makes my story just a wild guess.
Actually you can use Gecko in Konqueror. I believe kmozilla is part of kdebindings. Install it, and set your preference for html to kmozilla, instead of khtml.
When all you have is an encrypted SSL session how are you going to figure out if its a legitimate bit of ebusiness with a related company or someone in your company uploading your entire company customer database?
I dunno if I can agree here.
What exactly would be the difference between running ipsec over a firewall?
All the firewall admin will know is that there is data going over the ipsec interface.
That's just as much as when there is encrypted.net going over it (whatever.net is?).
Odd, but I always thought AMD was a bigger supporter of Open Source software. At least they are nice supporters of Mandrake, they supported the webserver of mandrakeuser.org i believe (or was it mandrakeforum.org?). On a lot of exhibitions they share their space with the guys from mandrake.
There is no real API on Linux for Multimedia. Right now it's all loose apps and libraries. The people of Gstreamer have started Gstreamer as a project to build such a standard, and to make it easy to build applications to use the Gstreamer framework. It's not ready yet, but it is being worked on.
Or you can just install gv. Galeon will embed the pdf into its window. Well, that used to work for me, but currently it doesnot, and I haven't looked into it. If you use Konqueror, install kghostview, and it will embed it too into a Konqueror window.

Q: Are rpms still such a pain in the ass to create?
A: In essence, Yes.
Duh, I meant No. And Yes, they are rather easy to build.
I never built deb packages though, so I can't really compare them.
