[SOLVED] Internet lag on slackware

drigohighlander · 03-24-2012, 06:55 PM

Hi,
I'm using Slackware 13.37 and Windows 7 in dual boot.
I use Slackware since it was hotplug, very old..but since 12.1 version I had the same problem.
The internet in windows 7 works very fine, I type the address of the desired site in the mozilla firefox bar and press enter, and it loads very faster, very very faster.
But in Slackware, in the same mozilla firefox version, when I press enter key, appears a balloon that say : looking up <site> ... so after, waiting to <site>... and then transfering.. that is very boring because it is a crazy lag, sometimes it blow your mind, I don't know what is wrong, my motherboard have two network output and everything is configured to the first one, I don't know if it is the problem, the slackware get the ip of a router, everything is automatic.
Somebody can help me?
It is a old problem for me.
thanks.

Just a few questions. You aren't giving us a lot to go on besides "it works in Windows but not in Slackware."

Are you using fixed IP or DHCP?
What happens when you access a www site via its IP address and not name?
Type of router?
DSL, cable modem, or ...?
What is output of ipconfig and lspci?
What is your network chipset?
Wrong kernel module?
Are you sure the second network port is disabled?
What happens when you plug both ports into your router?
Did you forget a setting in rc.inet1.conf, resolv.conf?
Conflict in /etc/network or /etc/sysctl.conf?

Oh yeah, sorry, I thought that it was simple, and not need to go deep.
Okey answering:

1 - I'm using dhcp. My /rc.inet1.conf is:

Code:

# Config information for eth0:
IPADDR[0]=""
NETMASK[0]=""
USE_DHCP[0]="yes"
DHCP_HOSTNAME[0]=""

...
# I put yes only for eth0, the other are all left in blank.

# Default gateway IP address:
GATEWAY="192.168.1.1"

...
# All configuration not showed here is default.

2 - Dude it's very fast, seems like windows or more fast, but there are websites that have half loaded and stuck in looking up...and have the same lag in this part, I guess that is maybe a external link, I don't know...

3 - Sorry, don't understood the question, Are you asking if it is wireless or not? If yes, it is wired, sorry for the (if is) stupid answer..

4 - DSL, but the modem is intregrated in the router, so when I turn it on, The router connect automatic on the internet, and I only have to put a cable in my pc up to router and run dhcp.

5 - I don't have ipconfig command in my distribution, lspci is:

(Yes I have 5 gpu plugged on it..)

6 - lspci says that it is Realtek Semiconductor Co., Ltd. RTL8111/8168B.

7 - I don't know lsmod show that use r8169 but it is automatic loaded.

8 - I don't know, ifconfig show only eth0 and lo, so I think that the second one is disabled.

9 - I don't know, I will try, I will get another cable. I don't have one now to test.

10 - The rc.inet1.conf I already showed, the resolv.conf is:

Code:

bash-4.1# cat /etc/resolv.conf 
# Generated by dhcpcd from eth0
# /etc/resolv.conf.head can replace this line
domain homestation
nameserver 192.168.1.1
# /etc/resolv.conf.tail can replace this line

11 - I only have /etc/networks (you wrote network, but must be the same..I guess..) in my system.

Code:

bash-4.1# cat /etc/networks 
#
# networks	This file describes a number of netname-to-address
#		mappings for the TCP/IP subsystem.  It is mostly
#		used at boot time, when no name servers are running.
#

loopback	127.0.0.0
localnet	127.0.0.0

Thanks for help.
And sorry for the big post and my bad english.

Sorry, I did mean "ifconfig" see thats what happens when you switch between Windows and Linux too often! And you: crazy kid with 5 GPU. Nuts.

You have the same network chipset as I do, so the kernel driver is not the problem. Type of router: You answered in part that you are using a DSL modem + router combination. What manufacturer and model? I have found that some are rather odd with Linux support.

If using direct www IP addresses is fast, you could have issues with your DNS access via your router. Also, I see that localnet is the same as the loopback; this could cause problems. If using direct www IP addresses is fast, you could have issues with your DNS access via your router.

I have a couple of suggestions:

in /etc/networks try changing "localnet 127.0.0.0" to "localnet 192.168.1.0"
access your DSL router web configuration and change your ISP provided DNS servers to another set. You can place these into resolv.conf above "nameserver 192.168.1.1"

I use OpenDNS.

Code:

208.67.222.222
208.67.220.220

Another idea, since you are wired, is to set up a static IP. Just make sure that your static IP doesn't conflict with some other device.

rc.inet1.conf:

Code:

# Config information for eth0:
IPADDR[0]="192.168.1.2"
NETMASK[0]="255.255.255.0"
USE_DHCP[0]=""
DHCP_HOSTNAME[0]=""

...

# Default gateway IP address:
GATEWAY="192.168.1.1"

/etc/resolv.conf

Code:

domain homestation
nameserver 208.67.222.222
nameserver 208.67.220.220

Also, check your /etc/hosts

Code:

# For loopbacking.
127.0.0.1		localhost

should be the only entry unless you want to do some ip to name mappings without running a local name server.

BTW, "lo" is the default loopback interface or your computer. Is is mapped to 127.0.0.1 and allows things like accessing the local web configuration utilities (http://localhost:631 for CUPS).

Sounds like DNS issues to me. Three remedies I've applied:
- edit resolv.conf (as above) to avoid using local router
- blacklist ipv6 module
- stop firefox from using ipv6 first via a setting in about:config (can't remember exactly how but a web search will find it quickly)

If you are using DHCP with a DSL modem/router then the default gateway will be supplied.
Try changing to

Code:

GATEWAY=""

Also you should not need this line in /etc/resolv.conf

Quote:

domain homestation

This is probably the cause of your problem. The DNS resolver is expecting to find a DNS server on your local system, which is not present, and so has to time out before the other nameservers are tried.

drigohighlander · 03-25-2012, 11:52 AM

Thanks for all answer guys.

I Tried some approaches, only one for time, and I will say what works and what not.

1 - change localhost in /etc/networks - sorry I not tried it yet.

2 - config my router to another isp - I don't have the admin pass of my router, them come pre configured from the internet provider, I don't know the pass, it's really cumbersome. (Some day I will ask, don't need it now, and its a fiberhome hg 110-b model)

3 - changing the dns of /etc/resolv.conf to 208.67.222.222 and 208.67.220.220 helped a lot! (Besides I have no idea what these numbers are, sorry). But some sites still stuck in the half loaded and then looking up... the same lag but only in some sites and when it will load external links...and I guess that is not the perfect solution because when I run rc.inet.1 (and it happens everytime when my pc turn on) all entry in resolv.conf are erased and its put homestation again (fu*k kidding me --).

4 - Left blank the GATEWAY in rc.inet1.conf didn't change anything.

5 - My /etc/hosts file is okey.

6 - I not tried to blacklist ipv6 module because...(see item 7)

7 - I do stop firefox using ipv6 via settings manager, and really it solves everything!!! (Even the /etc/resolv.conf with the homestation entry, the problematic entry). thanks a lot!!!

Thanks for your help guys.
2012 fall can came now...\o/ ha (I couldn't die with this very old problem.)

mrclisdue · 03-25-2012, 12:39 PM

Those *numbers* in your resolv.conf are for the opendns servers which will be overwritten on reboot unless you do one or both of the following.

In /etc/rc.d/rc.inet.conf, add this line;

DHCP_KEEPRESOLV[0]="yes"

and/or, issue this command:

$ chattr +i /etc/resolv.conf

This makes the file /etc/resolv.conf immutable (can't be changed, even by root). To undo, $ chattr -i /path_to_file

cheers,

Or set up a static ip address, which also prevents overwriting of resolv.conf.

Glad it worked out for you and thanks for the update on what happened.
