deathkrush Posted June 8, 2004 Report Share Posted June 8, 2004 I am running Mandrake 10 Official, 2.6.3-13 kernel and Mozilla Firefox as my browser. I never had any problems with internet connection until last week when I installed and started using MLDonkey file sharing client, OpenVPN and sshd. When clicking on a link Firefox would sometimes show a "Document contains no data" error. All I had to do was click on the link again and voila the website opens. But now this happens for every new link I click and it takes more than one click to connect to a website I want (eBay takes about five clicks). The strange thing is that once I do connect to a given URL, that website works fine for the rest of my browsing session, but every new link I click results in the error. I confirmed this to be a problem on all browsers (Konqueror gives me a similar error), on instant messaging clients, on both wireless and ethernet connection, on both DHCP and STATIC internet configurations. I tried disabling my firewall in the router and even setting my laptop as a DMZ host but that had no effect. I also disable IPv6 as some people suggested and tried using only one DNS entry in lookup.conf, still no luck. Clearing Firefox cache does nothing, because this is not a browser problem. Turning off MLDonkey OpenVPN and sshd services and restarting the computer doesn't cure the problem. Please help, I am going mad about this. I thought Linux was supposed to work well with Internet. This problem is inexistent on the same laptop with Windows XP running. Here is my ifconfig: eth1 Link encap:Ethernet HWaddr ***private*** inet addr:192.168.1.6 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3986071 errors:0 dropped:0 overruns:0 frame:0 TX packets:4885954 errors:9 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:826236594 (787.9 Mb) TX bytes:803140251 (765.9 Mb) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:402630 errors:0 dropped:0 overruns:0 frame:0 TX packets:402630 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:32028207 (30.5 Mb) TX bytes:32028207 (30.5 Mb) Quote Link to comment Share on other sites More sharing options...
fissy Posted June 8, 2004 Report Share Posted June 8, 2004 does sounds like a dns problem have you tried changing servers? Quote Link to comment Share on other sites More sharing options...
Cannonfodder Posted June 8, 2004 Report Share Posted June 8, 2004 Also, try this from a windows machine and see if the same problem exists. It would help you isolate whether the problem is OS related.. or outside your box.. Quote Link to comment Share on other sites More sharing options...
liquidzoo Posted June 8, 2004 Report Share Posted June 8, 2004 ...until last week when I installed and started using MLDonkey file sharing client, OpenVPN and sshd. Are all of these running when you're experiencing these problems? My guess is that something (most likely MLDonkey) is sucking up all of your bandwidth. Try throttling it down so it only uses, say, 50% of your available bandwidth and see if the problem still exists. For how to throttle it, see the MLDonkey website or the program's docs.

deathkrush Posted June 8, 2004 Author Report Share Posted June 8, 2004 Well I just went to resolv.conf and commented one of the DNS entries. This sort of helped and the error is not so frequent. eBay and Hotmail still give me major problems though because they use a lot of different servers. Windows XP on the same machine works fine as do all other computers in my home network. Quote Link to comment Share on other sites More sharing options...

I already disabled MLDonkey, sshd and OpenVPN and it didn't help. Also I have noticed that the same error sometimes happens for local addresses: 192.168.1.1, 127.0.0.1, etc. Quote Link to comment Share on other sites More sharing options...
streeter Posted June 8, 2004 Report Share Posted June 8, 2004 Are you using a proxy? Either on your PC, or at your ISP. Chris Quote Link to comment Share on other sites More sharing options...
Gowator Posted June 8, 2004 Report Share Posted June 8, 2004 This could be becuase something is sucking you BW like LZ says and hence the dns queries are timing out OR like streeter says a problem with the proxy. Since your ALSO using Windows have you tried Firefox in windows ? perhaps the ISP proxy is set using a MS specific script ? Have you tried just resolving addresses from the cli like nslookup or dig etc. on a name ? also then try this iwth the distributed ones like akamai, yahoo etc. and see what happens, it could be stale cache info .... My proxy at work today has decided google is in german today... LOL ahh well, Quote Link to comment Share on other sites More sharing options...
deathkrush Posted June 8, 2004 Author Report Share Posted June 8, 2004 I am not using a proxy, my provider is Comcast cable. I use Firefox as my default browser in Windows and it's fine no probems. I tried nslookup ebay.com and it worked, gave me an address 66.135.192.87. When I enter it into Firefox it results in document contains no data error but when I do it the second time it works as usual. The pictures don't show up but I hit refresh and they do. AOL Instant Messenger takes 10 retries to connect. The strangest thing is that when I am not running any appplications my bandwidth monitor shows constant 1Kb/s transfers. Maybe it's natural because I'm on wireless. Quote Link to comment Share on other sites More sharing options...
deathkrush Posted June 9, 2004 Author Report Share Posted June 9, 2004 I just installed Mandrake on another computer in my network, works great, no problems. This is definitely a software configuration issue. Quote Link to comment Share on other sites More sharing options...
streeter Posted June 9, 2004 Report Share Posted June 9, 2004 Any chance of connecting directly to your router by cable, thus ruling out/narrowing it down to the wireless connection? Also, can you post a detailed description of your network, ie what connects to what, through what etc (if that makes sense!) Please also post: Contents of /etc/resolv.conf Output of "iptables -nvL" Output of "iptables -nvL -t nat" Output of "ps aux" Output of "route -n" Are you 100% sure you are not going through a proxy - check the settings in Firefox. It is also possible you are getting routed through a proxy without your knowledge (that's what some of the above -might- tell us). I have seen exactly this behaviour before with squid and a satellite internet connection. Chris Quote Link to comment Share on other sites More sharing options...
Gowator Posted June 9, 2004 Report Share Posted June 9, 2004 Things that sprinmg to mind then: perhaps a issue with the network driver or way the card is configured ? something when you installed the VPN client ?? One thing to do is maybe to install webmin (if you havn't already) and delete the interface eth0 and everything to do with networking then reinstall .the interface and network.. I guess you could do it from the Mandrake wizards if they worked the first time ?? but I prefer doing it by hand or webmin and understanding..... Just out of interest.... perhaps try running apache on the second PC and connect to this over the LAN. That should at least say if its a routing problem or something else. and just a last check.... to see if the firewall somehow got activated ... ps -ef ¦ grep iptables see if it comes back with anything .. and ps -ef ¦ grep shorewall Quote Link to comment Share on other sites More sharing options...

Please also post: Contents of /etc/resolv.conf Output of "iptables -nvL" Output of "iptables -nvL -t nat" Output of "ps aux" Output of "route -n" Yes, I have tried it through a cable directly to my router, I disabled wireless just to make sure. Didn't help much, I am still getting the same error. Basically I have this all-in-one Linksys router (hub/gateway/router/wireless) that connects to a cable modem.

streeter Posted June 10, 2004 Report Share Posted June 10, 2004 Well, your firewall is wide open, so it's not that causing the problem. Any chance of doing a "ps aux > ~/log.psaux" ? This will send the output to a file called log.psaux in your home directory, which you can cut and paste from - reason being, the output above is truncated. I believe _pluto_adns is something to do with freeS/WAN, but don't know much about it, so perhaps the problem lies there - anybody? Perhaps all your data is being tunnelled through this VPN, and this is causing the problem?? As an aside, you have a few daemons running in there you may not need - rpc, portmap - best turned off if you don't need them. Chris Quote Link to comment Share on other sites More sharing options...
