What you're talking abot is ToS (Type of Service) and QoS (Quality of service)

 

if you are using ICMP packets, you can setup a router to prioritize (spelling :) ) the ICMP packet.

You have to manually prioritize the packet-type though, right? It's not a case of it being in some tcp/ip standard that has been included in a premium-brand routers' tcp/ip stack that can be utilized by swiching an extra bit in your ip-header?

If the packet is undefinable and you cannot use ToS, the you could invest in a couple of VLAN 802.1q routers that will do Port based QoS.

Won't that rely on the network-priority of the VLAN that has been set up? VLAN uses (I thought three) bits for setting priority. You wouldn't by chance know if it would be possible to 'melt' that into, say, ICMP packets / mask a VLAN packet like ICMP for a router, perhaps still keeping the rest of it's functionality intact?

Is a network standard that defines certain network packets having some primacy or state of urgency over another packet, what in turn would possibly have a router handle that one 'more important' packet first?

Fictitious Problem:

Let's say that I would have a mission-critical packet containing data that engages an emergency override/stop function on a piece of machinery. The goal would be to have emergency-stop buttons connected to one or more machines over a real busy ethernet cable (that is used for a broad number of other applications) without sacrificing any or all response time. Every second does after all count!

Could I in such a situation preferably use an ICMP packet because it is more 'important' than a standard data-packet, or is there no such thing in router-land?

Did your maxtor contain a swap partition when you where booting? Maybe you forgot to make one because -you know who- also just dumps theirs in the C:\ (oops, was that too obvious?).

Just wondering.

No one knows nothing?

[Deleted explanation]

Well, there's a better explanation then that I could of done ;)

Sean

Well... in windows you would use the obvious scandisk app...

Mandrake checks the filesystem every x-number of boots, so I don't think that that should worry you that much... Although! Might you want to check you linux file-systems manually you could use the 'fsck' application that can be found in the console --> Type 'man fsck' in the console for more info.

I hope to have informed you enough with this all...

Hi,

When I boot MDK 10.0, my 'lisa' seems to almost constantly take 80% or more of CPU resources... when I want to even ping a local machine on my network, this is what happens:

[root@h4x0r init.d]# ping 10.0.0.150

connect: No buffer space available

When I kill the 'off the scale' "lisa" PID, my 'buffer' seems to work once more... Weir.

Does any-one have a cure for this cold?

Sean

Help! I upgraded linux MDK my laptop from 9.1 to 10.0... I had a real good font for in Konsole (under KDE) and after the update it seems to be...lost?

Anyway... I am looking for a font that solves the problem of me having my MC drawn with 'blocks' instead of the usual lines... :S And it has to be small yet readable under 1024 x 768.

Does any-one have any tips???

Sean

UPDATE:

Hi guys... I found some info on the kernel-secure versions of the MDK kernel...

Name : kernel-secure-2.6.6.0.rc3.1mdk

Version : 1 Vendor : MandrakeSoft

Release : 1mdk Date : 2004-05-07 14:06:10

Group : System/Kernel and hardware Source RPM : kernel-2.6.6.0.rc3.1mdk-1-1mdk.src.rpm

Size : 19512141

Packager : Thomas Backlund < tmb_mandrake_org>

Summary : The Linux Kernel compiled for SECURE machines.

Description :

This package includes a SECURE version of the Linux 2.6.6

kernel. This package add options for kernel that make it more secure

for servers and such. See :

http://www.nsa.gov/selinux/

for list of features we have included.

For instructions for update, see:

http://www.mandrakesecure.net/en/kernelupdate.php

GrTz,

Sean

I think just every body knows about tripwire, hell, I even have their poster... I also know that there are similar products by other people on the web... The question: Who's tha bestest? :P (Spelt bad on purpose ofcourse!)

Sean

Ah, nice :) That shed some light ;)

Lol, you having nvidia driver problems with 2.6? I don't really have any driver problems as my 2.6 machine operates with minimal hardware anyway (home based server...).

I wonder if my laptop (with a ATI M 6000) will have any trouble as soon as I upgrade to 10... (Still on 9.1 on my laptop).

Sean

Sean is wondering what the exact differences are between say, these pre-compiled kernels:

kernel-2.6.6.0.rc3.1mdk-1-1mdk.i586.rpm; Standard issue kernel compiled with defaults?

kernel-BOOT-2.6.6.0.rc3.1mdk-1-1mdk.i586.rpm

kernel-enterprise-2.6.6.0.rc3.1mdk-1-1mdk.i586.rpm; Special load balancing for servers?

kernel-i686-up-4GB-2.6.6.0.rc3.1mdk-1-1mdk.i586.rpm; Custom compiled for efficientcy on i686 arch with upto 4 Gbyte of ram?

kernel-p3-smp-64GB-2.6.6.0.rc3.1mdk-1-1mdk.i586.rpm; For P-3 With up to 64 Gbyte of ram?

kernel-secure-2.6.6.0.rc3.1mdk-1-1mdk.i586.rpm; This would be extra secure?

kernel-smp-2.6.6.0.rc3.1mdk-1-1mdk.i586.rpm

What is the difference between the bunch, is there any one that could tell me what is special about every one of these pre-compiled kernels?

I have been running the 'kernel-secure-2.6.*' kernel-versions for the past couple of months, they are nice and stable... Why is this kernel more secure than any of the others [if it is so]?

I didn't seem to find much on this subject in my frantic search, so it would be cool to know more!

Sean

Steve,

Your a life-saver... Thanks mate!

Sean

p.s. 1 of 4 now running on 2.6 !!!

Hi guys,

First of all I am happy to hear that the official release of Linux 2.6 is out on te prowl! I want to thank all the hard-working kernel developers and contributers for their fantastic work. Keep it up!

My problem: I got MDK 2.6 kernel RPM from the great MDK-Cooker... Now when I want to urpmi the package is tells me that it needs like 4 dependencies. I have 3 of the 4 installed and am having problems with #4.

The package is "udev". It needs kernel >= 2.60 to install... yet 2.60 needs udev to install... HELP?

Thanks,

Sean

Okay, here is my problem:

My HP Omnibook 6100 (and another machine) don't seem to take full advantage of the 100Mbits NIC.

* When I copy files over my network, it doesn't go fasten than 3 Mbyte per second... SMB or FTP... Same thing...

Does any-one have any suggestions? I am on MDK 9.1.

Sean.

Whazzup, fellow MDK-Users?

I have 9.1 installed on a remote location, only now I am having web-server problems... Apache seems to be fine it self, but a php script that a friend made doesn't. No, it isn't the script... it has been tried on a server or two and seems to work fine!!!

I also heard from a friend that MDK 9.1 --> Apache + PHP --> Php was missing out on php.ini... might that be my problem???

I would love to hear the answer to my problem asap :P Then again, who wouldn't.

Sean

I am going to have my self a private dig on urpme & options/switches...

The only thing is that I might indeed only want urpmi to download the packages and let me install them, but I have to check it all out first. I am scared that the config might get f*cked up or something... Then again, I will need to find a way to backup certain stuff automatically anyway, so why not back it all up.... That would be the best option imho.

Anyway... urpmi it is then? Check it out, I shall... Find the path I will... And... I will keep you updated, would be cool if you would do the same :D

Sean.

One of these coming days I will most probably be planting a MDK box at the office as a general file server etc.

In MDK control centre you can click update, select updates, dload updates and it installs them automatically. Now, I want to keep the ammount of work to a minimum so I have 2 options.

- I don't update at all.

- I find a way to have the MDK box update automatically (without using/starting XFree).

I can help my self with the first option, but I can't even talk about the second one. Is there any-one that has any experience with, or knows of any way to create some form of an automatic update.

Would be cool to get some feedback....

Sean.

IF IT AINT BROKEN, DON'T FIX IT!!!

Those are wize words indeed....

Too bad that the editor is internal. Then again.. who cares... as long as it stays there! It's a real nice editor, and I am loving it. As just about every system comes with MC, I shouldn't care.. Just go MC then F4, and I am in ;)

Ow well...

Sean

What do you care if it is an active project or not... You can still fool arround with it if it isn't active.... Once your Java skills are 'sharp', you can start developing it further your self... Who knows.. Maybe become project leader or something.... ;)

The text-editor that can be found in MC, under the F4 Function key. Does it have a name, and is it something external? Does any-one know what it might be called?

Thx,

Sean

My favorate C tools are 2 Shells in X-Windows both running in one konsole window, the first one running 'MC' and it's F4 Editor, to do the actual C, The second for compiling the app that I am working on, without having to leave the F4 editor.

Windows can be swapped using the SHIFT + <--(arrow keys)-->.

If the possibility of opening 2 shells under a single konsole does not exist, I use ctrl+o to get to a clean shell to compile my program, and back into MC's editor without even shutting it.

What's your programming preference?

Sean.

Anyone try Thunderbird(mail)?

 

Thunderbird is a Mail-News client meant to compliment the Mozilla Firebird.  Thunderbird has support for IMAP, POP3, NNTP, multiple accounts, powerful filters, spell checking and a smart junk mail filter. Thunderbird is now built with Xft enabled and is my prefered Email program.

http://www.mozilla.org/projects/thunderbird/

As a matter of fact, I was looking at thunderbird. I haven't dloaded it as of yet though. It sounds good, and I am going to try it for sure!
