sudden internet slowdown when using suse, but not xp
 
i am currently running windows xp. this afternoon, our internet connection suddenly had a breakdown. the router did not seem to get signals and our provider told us we'll have to wait for technician. when i came back from training one of the people i live together with told me that internet was up again about one hour after i went out. running suse 10.1 i wanted to check my mail and loaded a forum, too. that worked very well until suddenly i lost connection again. no progress with firefox, opera or konqueror.
what could be the cause!? is it possible that my suse-system is being infected by a kind of virus!?

Kind of a guess on my part, but I'd run fsck to see if I hadn't gotten a disc error somewhere. There aren't many virii that can affect Linux so I'd be doubtful there. (That said I do have an anti-virus program just in case.)

thank you for your answer! what is "fsck"?
Code:

ungua@ungua:~> fsck
bash: fsck: command not found
ungua@ungua:~>

which program are you using? the problem for me is that our provider is very bad, i never know where the problem really lies.

Try running fsck as root. Run man fsck for more details.

thank you for your help! i'm very sorry if this is too newbie again, but i am not quite sure which option to choose from the manual. running "fsck" only, i get this message:
Code:

reiserfsck --check started at Sat Jan 27 12:16:54 2007
###########
Partition /dev/hda7 is mounted with write permissions, cannot check it
fsck.reiserfs /dev/hda7 failed (status 0x10). Run manually!

you can't fsck a disk you are mounted to. You have to unmount it first. Hopefully /dev/hda7 is not your root partition. If it is you will need to boot a livecd of Linux and run fsck from there. BTW, fsck is the program which inspects your filesystem for errors. If it finds them it will attempt to make repairs or will follow whatever instructions you give it, (such as those you find in "man fsck"

yes, hda7 is my "linux native" drive. i can run fsck from knoppix, is there anything i have to watch out for!?

If you know what format hda7 uses you should execute it this way...(I.E. you have ext2) fsck.ext2 /dev/hda7 and add any switches you desire. If you have reiserfs or jfs or whatever you would type fsck.something just the same substituting your particular format. If you don't know the format I think fsck can tell and will pick it if you just type fsck /dev/hda7 Just run it without any switches first and see what it says. If it says the volume is clean or not flagged dirty, there is a switch to make it do a check anyway. I always do that myself because fsck will sometimes refuse to do a check if the dirty flag is not set.

Open YaST, go to Network Services, DNS and Hostname and make sure you check that it "recieves dns from DHCP"

ungua 01-30-2007 11:39 AM

it norwegian it says something like "change host name via dhcp", i guess it is the same. it was not checked, so i am looking forward to find out if this has an effect! :) and i'll try the other tip soon, just have to have enough spare time first.
