Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I run Privoxy on the same machine as my browser. Until recently, everything worked just fine, but now it refuses to upload. When I tried to enter a site, it took extremely long to load. I tried other sites too, but same problem. I checked my network speed at www.speedtest.net. The ping check seemed to never finish, but when it did, it showed more than 10 sec ping. I found out that my download speed is just fine. My upload is another story. I have 1000 kbit upload, but the test showed just 30. I tried again without going through privoxy, and everything went back to normal.
I have tried to purge privoxy, and then reinstall it. No difference. I have tried both Opera and Firefox. Same problem. OS is Ubuntu.
I checked my network speed (..) The ping check seemed to never finish, but when it did, it showed more than 10 sec ping.
Your ping trouble makes me think of ISP-side network problems, not trouble with Privoxy. When the problem occurs again what would be interesting are network test results using something else that uses TCP like 'tcptraceroute' or 'lft' (not 'traceroute' as it uses UDP and not 'ping' as it uses ICMP). Sure you could post (attach?) your Privoxy configuration (please remove comments with 'grep -v "^#"' and remove empty lines), your network (and firewall) settings, and then some but I'd rather see network test results first.
Did a basic tcptraceroute. Didnt understand much of lft.
Here is the output of tcptraceroute:

Did the problem occur again, or was this a tcptraceroute "just because you can"? When the problem occurs again it would be good to trace a few more common sites like Sourceforge, Slashdot, Google, whatever else you fancy. That might help paint a better picture of network conditions. (Sure it would be more thorough to also use some Looking Glasses in geographically different locations using different backbones too, but OK...)
I did post the config further up in the thread. Anyway, i think i might have found the problem. It was not privoxy, but my router. I started to suspect that after i connected to another accesspoint on my network, and everything was just fine. I found a ticked checkbox marked "DNS relay", and unticked it. Now it seems like everything works again. Dont understand why that would confuse privoxy and not other network dependent programs though. Thanks for your help anyway
