[SOLVED] Can't browse/surf but transmission downloads.

Laxman_prodigy · 09-06-2012, 06:29 AM

Hi.
So, suddenly while browsing, it got very very slow accessing the webpages and started failing totally. Its Slackware 13.37 and the browsers are mozilla and opera. While Opera kept on opening pages later before the mozilla died on it. I can play Urban terror online with no problem. I have always used dhcpcd way to connect to the web. I am posting this from the Windows partition since its a dual boot and I kept it for the times like these.

I have tried to kill dhcpcd and re-run it with /sbin/dhcpcd. It forkes itself to the background, like the way it says. And the same story. No net browsing. I tried lynx to open google. It fails again. I am quite new to Slackware but have gotten that far from where I have become quite competent enough to troubleshoot any problems and hiccups with the great help of you guys.

Any info I should provide?

Thanks.

P.S And the browsing is fine with Windows 7.

Could be a DNS issue. Can you access websites by typing the IP instead of the domain name?

Hi WetDreams.

I understand what you mean but how do I know the IP address of sites I am browsing?! Still posting here from Windows installation coz its fine here. And it was fine under slackware too until recently. I have ran into no net issues until now. All I have been doing is running /sbin/dhcpcd as root sometimes polling used to cross the polling time limit while booting.

Send the results of the

# ping google.com

and

# route

and

# ifconfig -a

and

# tcpdump -v -i eth0

commands and the contents of /etc/resolve.conf

Note that on Slackware you should also have dhclient, try it.

Are you behind any firewalls?

business_kid · 09-06-2012, 08:26 AM

dhcpcd rewrites /etc/resolv.conf, which is a PITA, because if your router doesn't supply sensible dns servers, you end up with something like 192.168.0.1(the router) as dns :-/.

There is /etc/resolv.conf.head, which is a top for the new resolv.conf, and /etc/resolv.conf.tail, which is a bottom. I have opendns in the 'head file, so i see that. Also, if you pepper the RC scripts with DHCP_KEEPRESOLV="true" (rc.inet1.conf & rc.wireless.conf) it helps, although they still get overwritten occasionally :-/.

Hi everyone..

I'm not behind any firewalls. I will try the commands given and post the results soon. It seems that I can ping the sites and the lynx works too,just not the GUI browsers.I even tried installing opera through wine and it worked for a while but soon it failed too.

You do not need wine for Opera. It is possible to install it via a Slackware package created by a slackbuild from slackbuilds.org. I recommend uninstalling mozilla-firefox and re-installing via slackpkg.

Laxman_prodigy · 09-06-2012, 09:54 AM

I meant to say that I even tried through wine,I already had opera installed through slackbuilds but it wasn't working so I removed it. I had mozilla too from the slackbuilds.I have again installed opera through slackbuild as I had the build already in my Downloads.The problem is no matter what browser I install I can't surf. I can ping,can download through bittorrent,play online but just can't browse!It sometimes used to happen in windows too and I used to manually change IP addresses and it used to work,though I've currently put it to automatic IP setting and its working nonetheless. And what about the outputs I posted? Any clues there?

Laxman_prodigy · 09-06-2012, 12:45 PM

Hey guys...I resolved the issue. It seems like a DNS issue. I had to edit the /etc/rc.d/rc.inet1.conf and put the IPs,mask and gateway manually and I disabled DHCP too. I also gave the DNS name servers in the resolv.conf manually and restarted the rc.inet1. And now its working fine. Thanks for the support.

ChrisAbela · 09-06-2012, 01:44 PM

I am glad you resolved it (practically on your own).

Laxman_prodigy · 09-07-2012, 01:41 AM

Not without the tips here!
