I'm moving to Vietnam soon and was wondering if anyone knows of the best native linux way to circumvent the internet censorship there without slowing it down too significantly. I used to use proxy servers to access Wikipedia in China, but they were slow and unreliable. Not to mention, it was a pain to enable/disable it.
View 4 RepliesI have recently started using Ubuntu, so far I am quite satisfied with the switch in OS. This time my question has more to do with privacy, govt. sniffing of private/personal communications, Internet censorship and what to do about these issues. I live in a South American country where the govt. wants to impose Internet censorship such as the one currently in place in Iran, Cuba or China. They plan to set up a single node for all Internet communications out-going and in-coming. I would not be surprised if they are already monitoring people`s communications illegally.
1. what can be done to avoid being censored? they will be able to monitor my email accounts, facebook, twitter and so on. They want to force the Internet Service Providers and telecom companies to censor their users, since those companies will be responsible for the content of the emails, sms, tweeter messages, etc.
2. What can I do to avoid their censorship of certain contents which are critical of the govt. or contrary to the regime`s views? I need to be able to read what other people are saying beyond the borders of this country. We can`t tolerate living with this ban. Certain contents coming from abroad will be blocked.
3. How can I protect my email and bank operations? Is a proxy server an option? I really don`t know what a proxy server is, how much it would help us avoid govt. sniffing in private matters for political reasons.
4. what additional measures can be taken? is using encrypted messages an option to communicate with my relatives in order to prevent the govt. from reading my emails?
When I am running Ktorrent it takes about 30 seconds for a web page to open, in stead of 1 or 2 seconds. The download speed is very slow 200B/s and the status of most of the torrents is "Stalled". If have opened TCP and UDP ports 36477 4444 6881, 7881, 8881 and added them to the port forwarding list in my router. No difference.

The manufacturer put a password on there so that only it's program could open it. I do not use that program, but it has information I need. Is there a way to find that password or circumvent the password altogether?
View 1 Replies View RelatedHas anyone else noticed that file transfers on Maverick are significantly slower than on Lucid? A review of Maverick on Tom's Hardware finds that it is considerably slower. My own test says: On 10.10, file copy between two NTFS drives maxes at 30 MBytes/s; on 10.04.1, the same operations clock in at 40 MBytes/s. Both drives are capable of rw speeds of 70-90 MBytes/s, which I got on WinXP, and hdparm's cached read results back that up. Any ideas why file transfers are so slow, and especially why Maverick is even slower than Lucid?

Whilst I get between 18 and 19 mbs on Vista I only get 4.5 on Ubuntu - how do I fix this - is it an issue with my ethernet drivers or my setup?

Months ago one of my computers died. I have bought a brand new one laptop, but I have a problem at the moment I wanted to install Ubuntu in dual boot with Windows 7: the new partition that windows 7 reserves for securing system files.
There are three partitions: Windows 7 principal, Windows 7 for securing system files (at the drive's beginning) and the recovery partition that HP puts there. Then I only have option to resize the Windows principal partition and get another principal partition. My question is if you know how to deal with this?
The other option you can help me is to advise me about some external hard drives to install ubuntu in them and don't touch the internal disk of my laptop.
I have a single 6.2Gb file that needs to go on a fat32 format hdd, does anyone know of a way to split the file so it will fit.

Does Wubi perform significantly better than an Ubuntu version installed on VMWare or VirtualBox?

I don't know about you, but I have found the linux kernel to read pretty much any usb drive or sd card, while many bioses, especially, when they are older fail miserably. Now if you got yourself a machine which bios cannot boot from your 16 giga stick, wouldn't it be possible to use linux as kind of a bootstrap, install it on a 1 giga medium, that the bios can boot from and then when the linux kernel is running, give control to the other media that you really want to boot from. This should be doable.
It is basically going from a running kernel and its inird to give control over to another grub or syslinux. Does anybody know if this exists already? Truth is that many bioses are just garbage, old and fail at pretty much all new hardware, so why not use a linux kernel as a crutch, to get away from this old piece of junk? I did similar things already with a software raid, where i had a machine that couldn't boot from a HD that was larger than 150 giga.
I installed a 10 gb HD to put /boot on it and then give control over to some "fancy 21st century technology that can boot from this HUUUGE disks" (as from my dripping from sarcasm voice you can tell that pretty much all BIOSes are a thorn in my side and a P.I.T.A. for me, too often they only do 30% of what I expect them to)
I'm running Ubuntu 9.10 on Athlon Barton 2600+ 2.2GHz, 1GB RAM and ATi Radeon X800 computer at 1600x1200 resolution with 2d (no compositing like Compiz).
Looking into the trouble of slow windows resizing I ended up with the observation that for 1280x1024 it's reasonably fast while at 1024x768 it's extremely fast. But 1600x1200 is my LCD's native resolution.
At 1600x1200 my computer is quite slowly responding, resizing windows or moving columns width makes it stumbling, you can see the action clearly does not go right with mouse, it's always late. KDE 4.x is way slower than Gnome.
I've tried many graphic cards (ATi, NVidia) with all possible drivers - open and proprietary, with or without 3d compositing.
Some graphic parameters:
GL_VERSION: 1.5 Mesa 7.6
GL_VENDOR: DRI R300 Project
GL_RENDERER: Mesa DRI R300 (R420 4A4A) 20090101 AGP 8x x86/MMX+/3DNow!+/SSE TCL
Glxgears gives ~4000fps with windowed mode and ~400fps at 1600x1200 maximized window. What is extremely amazing for me is that windowed mode takes 100% processor usage while 1600x200 maximized window (with window decorations) takes 30% of it, don't understand it.
Windows XP seems not to take care about 1600x1200 resolution, it's really fast.

A few months ago I invested in a very nice, expensive high performance mouse with very high resolution tracking. In Fedora 12 it is just too fast for me though, and I'm already well on the way to Carpel tunnel syndrome..
I have turned the sensitivity and acceleration down as far as they go but it is still too fast. The old ways of adjusting xorg parameters are, I understand it, now null and void due to the hotplugging HAL framework.

about every second time when I start up my Ubuntu 10.4, my hard drive starts to work heavily. While it's doing so I see in the system monitor that the gnome-settings-daemon has the status 'uninterruptible'. After about 3 minutes the hard drive calms down and the status of gnome-settings-daemon switches to 'sleeping'. so from that I guess the heavy working of the hard drive is somehow related to that process. Sometimes gnome-settings-daemon seems to crash completely so that my theme is gone.
So is there a solution to that? because it's annoying that it slows down the system for about 3 minutes after start up. On the net I've found some old threads from 2004 and 2006 which describe crashing of gnome-settings-daemon. But there didn't seem to be a solution.

View 3 Replies View RelatedAs mentioned in another of my recent posts, I have set up a small network for my job, in which I am utilizing 4 Servers running Ubuntu 9.04 Jaunty Jackalope Gnome GUI and Ubuntu Server running underneath (yes I need a GUI for what I am doing). However, I am having a problem when bringing Ubuntu out of "locked" state, and any time that I am required to authenticate (i.e. sudo bash). After I type in my password, everything hangs for a good 3+ minutes.
To test this, I disconnected the Ubuntu Servers from the network, and I tried to authenticate again. With the server off the network, authentication did not hang, and the GUI came up in seconds. Also, I checked my syslog and memory utilization and both are well within acceptable range that they would not be causing sluggish performance.
With all of this said, I believe that there is some kind of resolution going on when trying to authenticate while the servers are connected to the network (i.e. Kind of like how doing a traceroute in a cmd prompt in Windows without the "-d" takes forever because of name resolution checking).I should also mention that my network DOES NOT have an internet connection by design.

when calling 'top' dbus is having load of activity ('dbus-monitor --session') outputs also a lot of action (see attachement). this has effect that my machine is slowing down and normal work takes ages.I have no clue where the activity is coming from. I also had a look at https://bugs.launchpad.net/ubuntu/+s...or/+bug/441828. But there are no unnormal devices plugged in... (just keyboard + cordless mouse).when starting the machine the cpu load is ~9%. After a while (after 1 day) it goes up to 70-80%. the started applications do not change during that time. so i guess somewhere there is a leak.

I have a tenda wireless adaptor running on 11.04 natty. The USB id is: 148F 3070
Using the already installed drivers rt2800usb it can connect to all 13 channels but is very flaky, transfers slowing and stopping regularly. The rt2870sta driver is a lot more stable, but it will only connect to channels 1-11, but I need to use channel 13 due to massive wifi congestion on other channels...
I've tried iwpriv but it says there are no ioctls for the device.
Is there any way to get the installed driver rt2870sta to scan and connect to channel 13?

Today I noticed my Desktop was being controlled remotely from over the Internet even though I had it set for 'local network only'. Foolishly I relied on this setting and hadn't specified a password or other security. The remote user had opened my Firefox passwords page and was perusing this when I pulled the plug.
All external checks confirmed that my router/firewall is actively blocking correctly. How could this happen? How can I prevent this in the future? I had recently install the Firefox extension for Weave Sync and wonder if that had anything to do with it?
I administer a desktop computer with ubuntu 8.04 in an university library. Since it works almost all night, to enable students to study, after some time I noticed some misuses of the computer during the evening, when there isn't many students. My goal was to disable users from accessing internet from 7pm to 7am, but also enable it if certain user was logged in (I use that user for torrent, and I seed on that computers from time to time). So I created a script that's being called by root's crontab, and here is the script's code:
Code:
#!/bin/bash
NUM=`who|grep myuser|wc -l`
#echo $NUM
if [ $NUM -le 0 ]; then
/sbin/ifconfig eth0 down
else
/sbin/ifconfig eth0 up
fi
Since I created the script, I actually never seeded anything, so I'm wondering now if that's going to work at all, and (also) is there a better solution for this.
