[SOLVED] Internet 'delay': Web browser and even pacman don't connect

jtheripper93 · 2014-06-19 02:00:29

Hello arch community. I'm a new arch linux user. Right now I'm very excited running and discovering Arch and the Wiki. Thank all the community efforts to make this the great distro it is.

It is very wierd. Everything that uses internet connection don't work the first try. This affects all my programs: curl, firefox, and even pacman.
Using networkManager with Cinnamon. NetworkManager is using dhcpcd.
Because this is my desktop PC, I'm using a wired connection. On my other Linux (linux mint), everything is fine.

e.g, with pacman:

I open a terminal and try to install some package with pacman:

Packages (8): clucene-2.3.3.4-8  hyphen-2.8.6-1  libreoffice-common-4.2.4-2  libreoffice-pt-BR-4.2.4-2  raptor-2.0.13-2  rasqal-1:0.9.32-1  redland-1:1.0.17-2
              libreoffice-writer-4.2.4-2

Total Installed Size:   334.92 MiB

then, right after that, if I try again:

It works normally.

As a diagnostic test, you could (temporarily) disable IPv6.

samiam · 2014-06-19 02:08:41

Sounds like a slow DNS server somewhere, or one that's down.

for H in $(grep nameserver /etc/resolv.conf | cut -d ' ' -f 2); do echo "Asking ${H} for mirror.nl.leaseweb.net"; time host mirror.nl.leaseweb.net ${H}; done

Thank you both for the quick answer.

I'm going to try that right away. But, if it matters, I did configured NetworkManager to ignore ipv6 settings..

I did that, and:

$ for H in $(grep nameserver /etc/resolv.conf | cut -d ' ' -f 2); do echo "Asking ${H} for mirror.nl.leaseweb.net"; time host mirror.nl.leaseweb.net ${H}; done
Asking 192.168.1.1 for mirror.nl.leaseweb.net
Using domain server:

Aliases: 

mirror.nl.leaseweb.net has address 94.75.223.121
Host mirror.nl.leaseweb.net.domain.name not found: 5(REFUSED)

real	0m0.376s
user	0m0.003s
sys	0m0.007s

Hope it helps.

What the ... ?!

Run 'hostname', 'domainname' and 'cat /etc/resolv.conf' and report back

That's what I figured. Every time your system does a DNS lookup it first does it for whatever.you.typed.com.domain.name before doing it correctly. That's being set by your DHCP server, which I'm guessing is a consumer router. Remove that line from resolv.conf and see if things improve. If they do, find that setting in your router and remove domain.name.

EDIT: And actually - it might be that your router thinks it's a DNS server when it isn't. Try this too:

host www.google.com 192.168.1.1

Indeed it worked! Thank you! Problem Solved!

I did removed the domain line from resolv.conf, then worked in my router and found the domain thing. Erased that line from the form and now it's fine.
