Hi,
are your /etc/hosts and /etc/hostname files set up correctly?

Hi,
I think it is a problem with your /etc/resolv.conf where your DNS server are stored. If you have no network connection your computer hast to wait for a timeout before he can continue.
Perhaps you should try to insert your own computer into /etc/resolv.conf

Hi,

I just installed a fresh copy of Mandrake 9.1 with KDE 3.1 and had this same problem.

When logged in as a user applications took about 10 seconds to load. If I su'ed to root (sudo or su -) the same applications loaded nearly instantly.

I added the ip address and host name to the dns system and the problems went away... now just to see what happens when I go home and login...

I added both the forward and reverse address btw.

It sounds like the time-out thing for sure. Had a similar problem when I installed Linux at work. I had enabled the option to get the hostname through the DHCP server, which made KDE slow, since the server never delivered a hostname.

I have exactly the same problem, although I have a very unreliable provider instead of a laptop :roll:
anyway, when i'm connected i can use the internet and everything wokrs fine, but as soon as i get disconnected (which could happen any moment now), kde becomes unbearable slow.

now, i'm a real rookie, installed linux (SuSE 8.2) a couple of hours ago. I have absolutely no idea, where to put what in the files you just mentioned. Does anyone know where i can find good tutorials for this kind of stuff?

thanks

Out of curiosity - What is the time-out length by default when a DNS request is botched?

I *believe* I am having this same problem (well, I have the same symptoms - but I am not sure it's a derivitive of the same actual problem). My issue is just about as unpredictable... except it happens _very often_ so I'm not completely sure it's the DNS server... even still, I will add myself to resolve.conf

My particular symptoms are the above, except this hang can happen any time. It won't happen unattended as far as I can see... meaning it's not like it just up and crashes (but it could, i havent had it running long enough to tell). When I do something - nothing, or anything - in KDE that somehow triggers that... be it open a file menu and select an option that has a sub menu... or go to a web page... etc... The system will selectively hang. It is fun to watch actually... either everything will become unavailable, or it will slowly go dead in stages... just the task bar, then just anything network related... or, if I try to run the "top" command - it doesn't go... it hangs. If I am able to catch this and ctrl-alt-backspace and by rare luck get out of kdm/X and am dropped to a hostname login: prompt --- when I enter a username (any username), the login just hangs... you all seeing a pattern here? IT HANGS constently.

So far my transition off of Windows onto the OS I'm more at home on hasn't gone as expected. I hope someone can shed some light onto why this is happening... is it the same issue? What should I do to try and narrow down the bug?

Thanks!

digital_usa,

The timeout on DHCP is 10 seconds. It can be adjusted by adding -tx to the line that calls the daemon. (x being the amount of time to wait.)

Your hangup problem sounds rather like a daemon using all the resources.
Maybe you can find a correlation between what you are doing just prior to the "hang" everytime?

Firstly - I meant a DNS query, not a DHCP query..

As for narrowing the last action down... I can't say that any particular action or action group has been singled out at all. It happens as root, and as a normal user... happens with much running or little running...

Well, let me give you some background and enviro information

I'm running:
AMD AthlonXP 1800+
1 Gig of Ram
240 Gigs of HD space in the following denominations:
-- 100 gig /dev/hde (two ntfs partitions (40 gig), 4 swap/ext3 partitions (60 gig))
-- 100 gig /dev/hdg (one ntfs)
-- 40 gig /dev/hdh (one ntfs)

nVidia GeForce2 Ultra 64
3Dfx Banshee PCI (in all its lame VESA glory)
3Dfx Voodoo 3 PCI

Gentoo 1.4
KDE 3.1.1a
XFree86 4.3.X
Xinerama mode for use on three monitors, all at the same resolution of 1280x1024
All Xinerama options enabled in KDE (does not affect the hang case)

Input --
Microsoft 'blue' USB optical mouse (/dev/input/mice w/ zAxixMapping and IMPS/2)
Microsoft Natural Keyboard Pro

So far I've been able to hang the system by:

Clicking "Tools" or "Buddies" in gaim and selecting a sub menu *SOMETIMES*
Going to a unresponsive website *SOMETIMES* (made me think DNS)
While screwing around doing normal stuff like opening program menus etc from the K Start menu... etc...

Pretty much anything and nothing triggers it... its completely random in appearance... but im sure there is a root cause. What's strange is... when a process hangs... like when gaim hung, I can't kill -9 it... it just goes HAH IM STILL HERE! and gives me a slightly amused look, followed by another shell prompt as a way of mocking me. Sometimes I will assert my supposed superiority with a "reboot" command or even "shutdown -p now"... but it claims diplomatic immunity (no basis outlined) and refuses to comply... *SOMETIMES*

This is a very wierd hang point that can *sometimes* be waited through... but not usually.

Thanks for all your help!

Doh, :oops:

Need coffee...., should have reread the post.

You will have to disable things you can (KDE related) and see what help. maybe it is sound related (Do you have sound effects enabled?) disable arts and see if it helps.

Hey,

Possibly a good call there - I *may have been* running xMMS either streaming from www.di.fm or playing locally of a mounted ntfs drive (is that advisable?) in each case it hung...... but it kept playing through the hang... even if it was streaming. Many things continue working until they too become defunct.... so i don't know :-/

I run Gentoo(updated weekly for the last year and a half ) and I listen to streams all day long, but it could have to do with the specific hardware/software combo's. The sound is just the first thing that came to mind. I would also take out the extra two video cards for a test....

ahh! cant do that! Taking out video cards is not an option :-/ I know that it would help in testing, but right now - I cant afford to lose more time on this than I have... I would prefer to pull the cards out of the config ... this box is all big and full of stuff... pulling video cards out is a big dramatic production :-/

I was trying to eliminate hardware conflicts as well, but failing that just taking them out of the X11 config could help. Try disabling arts first though.

I had the same problem with my laptop. I have a Mandrake 9.1 installed. My problem is that everytime I launch an application under KDE it takes a lot of time to spawn just doing nothing. If I unplug the ethernet cable it's hell. Every application needs over 10 seconds to be displaied. This is really unbearable. It looks like all my applications need to comunicate with the dns server everytime they start up.

I tried to catch the packets and I found two connections: the first one to the dns server and the second one to the multicast dns (I mean 224.0.0.251:5353). I don't know what these connections are for.

I tried to debug the problem and it looks like this nasty thing is related with the kdmserver. But I'm out of ideas now. I don't know why it had to do a dns request everytime I open an application and I don't know how to prevent this. Once the DNS server had gone down and on my computer was hell. Is this possible?

If you have some ideas please answer this post.

Thank you
Giulio

Ok, I've worked around the problem. It seems that everytime I launch a KDE application it needs to resolve mycomputername address. Why this? I don't know. However it was enough to add the following line to the file /etc/hosts:
127.0.0.1 mycomputername
So everytime it needs to resolve the computer name it no longer ask this to the dns server.
I think, however, that this is a really nasty bug. How could a newbie installing the Mandrake for the first time manage a problem like this? Shouldn't someone correct it?
